Abstract
Background: One of the critical unit in each hospital is intensive care unit (ICU). The United States’ Environmental Protection Agency (EPA) recommends to control the noise level of this unit in order to not exceed 45 decibels (dBA) during the day and 35 dBA at night. In this study, our goal was to evaluate the noise level at adult and neonatal ICUs at some Sanandaj’s hospitals, Iran. Methods: This cross-sectional study was conducted from May 4th to June 4th 2012 in adult and neonatal intensive care units at three major hospitals in Sanandaj (Besat, Tohid and Tamin-Ejtemaei). In order to assess the noise level properly, measurements obtained during the days and nights. At a given day, a unit was selected randomly and measurement of sound levels obtained successively within two-hour periods. The noise levels were measured in decibels using a sound level meter (SLM). This process took four weeks to be completed (one week per unit). In the end of study, the total of 336 records of noise levels were obtained. Descriptive analysis as well as fitting a mixed effect models were used to interpret collected observations. All statistical analysis performed using R developed by R core team. Results: The preliminary analysis of observations showed that mean level of noise varied from 65 to 71 dBA among ICUs under study. Noise levels during the day were slightly higher than that of were observed during the night. Descriptive analysis of observations showed no major differences between the noise levels over the time and between the days/nights. Fitting a mixed-effects model showed significant differences of the noise levels between ICUs (P< 0.001). Conclusion: We found the noise levels were always above the EPA thresholds at all three hospitals both during the day and night. It is recommended to train hospital officials and staffs for keeping noise levels to an acceptable level.

Abstract
Background: Over the last two decades invasive candidiasis has become an increasing problem in neonatal intensive care units (NICUs). Colonization of skin and mucous membranes with Candida spp. is important factor in the pathogenesis of neonatal infection and several colonized sites are major risk factors evoking higher frequencies of progression to invasive candidiasis. The aim of this study was to detect Candida colonization in NICU patients.
Methods: This cross-sectional study was conducted on 93 neonates in NICUs at Imam Khomeini and Children Medical Center Hospitals in Tehran. Cutaneous and mucous membrane samples obtained at first, third, and seventh days of patients’ stay in NICUs during nine months from August 2013 to May 2014. The samples were primarily cultured on CHROMagar Candida medium. The cultured media were incubated at 35°C for 48h and evaluated based on colony color produced on CHROMagar Candida. In addition, isolated colonies were cultured on Corn Meal Agar medium supplemented with tween 80 for identification of Candida spp. based on their morphology. Finally, polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was performed for definite identification of isolated species.
Results: Colonization by Candida spp. was occurred in 20.43% of neonates. Fifteen and four patients colonized with one and two different Candida spp., respectively. Isolated Candida spp. identified as; C. parapsilosis (n: 10), C. albicans (n: 7), C. tropicalis (n: 3), C. guilliermondii (n: 2), and C. krusei (n: 1). In present study non-albicans Candia species were dominant (69.56%) and C. parapsilosis was the most frequent isolate (43.47%). Using Fisher's exact test, the correlation between fungal colonization with low birth weight, low gestational age, and duration of hospital stay was found to be statistically significant (P=0.003).
Conclusion: The results of this study imply to the candida species colonization of neonates. Neonates in NICU are at the highest risk for severe infection with Candida parapsilosis. Therefore, isolation of C. parapsilosis as the most common species (43.47%) in present study was noteworthy.

Abstract
Background: Fungal infections especially Candida species are frequent cause of mortality and morbidity in very low-birth-weight (VLBW) infants receiving intensive care; Candida infections are tissue invasive. This infection increases the risks of adverse neurodevelopmental sequelae. Prevention and treatment of fungal infection is so important in very VLBW infants. The aim of this study was to determine the prophylactic effect of fluconazole in decreasing the mortality and morbidity in VLBW infants (less than 1500gr) admitted in NICU.
Methods: This prospective case control study were conducted among 102 Infants (weighing less than 1500gr at birth at born) admitted in NICU department of Ali Asghar University Hospital from 2012 to 2013, Tehran, Iran. Weigh of birth in cases and groups were less than 1500 gr and both were culture negative. Cases received oral fluconazole 3 mg/kg in 3 days in 1st and 2nd weeks, alternate day in 3rd and 4th weeks, daily in 5th and 6th weeks. Control groups had not received fluconazole. Mortality and morbidity and hospital stay were compared between cases and controls groups.
Results: We studied 49 very low-birth-weight infants with negative culture as cases (received fluconazole prophylaxis), 46 VLBW infants without fluconazole profilaxy (controls). No significant difference in gestational age (P=0.2), and mean weights (P=0.4) were observed between cases and controls. The mortality rate 8.7% (n=4) in controls (without prophylactic fluconazole) observed vs 2% (n=1) mortality rate in VLBW cases (with prophylactic fluconazole). Although the mortality rate in controls was 4 times higher than cases, but without significant differences (P=0.1). Indeed, mean duration of hospital stay in controls was longer than cases (28.41±9.93 vs 19.85±6.19 days, P=0.00001).
Conclusion: Although prophylactic fluconazole in VLBW could decrease the mortality of cases (control the fungal infection) 4 fold in compare with controls (no treatment), it was not significant. The prophylactic effect of fluconazole might decrease the length of hospital stay of VLBW neonates in NICU. Due to limited number of cases and control. For further decision about prophylactic use of fluconazole, prospective RCT studies with larger cases and control would be helpful in future.

Abstract
Background: The ability to recognize the severity of the disease in those who their survival depend entirely on admission to the intensive care unit, is very valuable clinically. This study aimed to evaluate the clinical effectiveness of modified sequential organ failure assessment (MSOFA) scale to predict mortality and length of stay in intensive care unit patients respectively.
Methods: This was a retrospective cross-sectional study conducted on hospital records of patients admitted to the intensive care unit. All patients’ records who admitted to the intensive care unit of Kowsar Hospital, Semnan city (the capital of the province), Iran, in 2015 considered as the sample. Collecting data were done during 4 weeks in April and May 2016. The data collection tool was a demographic questionnaire and modified sequential organ failure assessment scale. Exclusion criteria included discharge in the first 24 hours after admission, the patient died a few hours after admission and incomplete information to complete the modified sequential organ failure assessment form.
Results: The study of 105 patients' records of the intensive care unit showed that 45.7% of patients were died, 15.2% and 39% were discharged and moved to other wards respectively. The results of logistic regression analysis and receiver operating characteristic (ROC) curve showed that this criterion had moderate sensitivity and specificity for prediction of mortality and length of stay in ICU patients (Area=0.635, CI= 0.527-0.743) and each unit increase in modified sequential organ failure assessment score is accompanied by increasing 32 percent chance of death (OR=1.325; 95% CI:1.129,1.555; P= 0.001(. Also each unit increase in modified sequential organ failure assessment (MSOFA) score accompanied by increasing 19% length of stay in ICU (OR=1.191; 95% CI: 1.034, 1.371; P= 0.015(.
Conclusion: The results of this study showed that the modified sequential organ failure assessment scale is not useful tool to predict the length of stay and mortality of patients admitted to the intensive care unit.

Abstract
Background: Bacterial sepsis is a main cause of mortality and morbidity especially in preterm newborns. The aim of this study was to search the bacterial etiologies of neonatal sepsis in NICU admitted preterm neonates.
Methods: A descriptive cross-sectional study had done in NICU of Ali Asghar Hospital, Tehran, Iran from March 2007 to March 2009. Seventy septicemic preterm newborns (<37 weeks) were studied. At admission day, for blood culture, 1-2 ml of venous blood was drawn after swabbing the venipuncture site with alcohol. After centrifugation of blood samples, deposits were cultured on sheep blood agar and incubated in a candle jar at 37 °C for 48 h and followed by subcultured. Isolates were identified using standard techniques (Nima pouyesh, Iran). Type of isolated bacterial organisms determined. Its correlation with gestational age, birth weight, premature rupture of membranes (PROM) and other variables determined we used the nonparametric two independent sample test, Mann-Whitney U test. Chi-square values (CI 95%, P< 0.05) were calculated for all categorical variables. P-value less than 0.05 considered statistically significant.
Results: Of 70 studied septicemic preterm cases, 17 (10.6%) cases had positive blood culture. Overall gram-negative organisms were more frequent than gram-positive organisms, Klebsiella (K.) pneumoniae, Escherichia (E.) coli and Staphylococcus (S.) aureus organisms were the 3 common causes of bacterial sepsis in studied cases. Early onset sepsis produced by K. pneumonia (40%), E. coli (20%) and S. aureus (20%). K. pneumonia, E. coli, S. aureus had equal incidence in late onset sepsis (26.8%). K. pneumonia was more frequent in early onset sepsis (P= 0.05), and in low birth weight (< 1500 g) neonates (P= 0.005, and PROM (P= 0.05).
|
Conclusion: Three causes for sepsis in premature newborns were determined: K. pneumonia, E. coli and S. aureus, it is so important for initial antibiotic treatment in admission day. Low birth weight, prematurity, and, PROM were the common risk factors for sepsis in cases. By preventing of low birth weight, low gestational age, and PROM the risk of sepsis could be decreased. We recommend empiric antibiotic in septic preterm newborns which can cover: K. pneumonia, E. coli and S. aureus in our center. |

Abstract
Background: Prolonged mechanical ventilation and the need for tracheal intubation are the main indication of tracheostomy. This procedure can be done, in two ways: surgical tracheostomy or percutaneous tracheostomy. In this study, surgical tracheostomy was compared with percutaneous method in the intensive care unit.
Methods: This clinical trial study was performed on 61 patients admitted to the intensive care unit of Ayatollah Rohani Hospital of Babol University of Medical Sciences from April 14, 2013 to April 14, 2016. In the first group (44 cases), tracheostomy was performed in percutaneous (PDT) and in the second group (17 patients) surgically. The early complications and waiting time (intubation to tracheostomy) for tracheostomy were compared in two groups. All data were analyzed by SPSS software, ver. 22 (Armonk, NY, USA), Analysis of variance (ANOVA) and P values of less than 0.05 were considered significant.
Results: The mean age of the patients was 59.87±8.15 years. The mean age of the male patients was 59.66±6.35 years and the female patients were 60.35±6.41 years. In this study, the average waiting time (time from intubation to tracheostomy) was 14.19 days in the PDT group and 20.69 days in the tracheostomy group, with a significant difference between the two groups (P= 0.001). The incidence of preoperative bleeding after surgery was five cases (8.2%). In the PDT group, two cases (3/3%) and the surgical group was three cases (4.9%) and the two groups did not have a significant difference (P= 0.46). The incidence of wound infection (during the period of admission and up to ten days later) in two groups was two patients (3.3%), one case (1.6%) In the PDT group, and one case (1.6%) in a surgical group and the two groups did not have a significant difference (P= 0.43). Other complications such a subcutaneous emphysema and posterior tracheal wall trauma and rupture was not shown in both groups.
Conclusion: The findings of this study showed that the complications (bleeding and wound infections) did not differ between the two groups. Due to the lower waiting time and the lack of need for patient transfer outside of the intensive care unit, percutaneous tracheostomy can be a safe alternative to the surgical tracheostomy.

Abstract
Background: Infant mortality is important as a standard indicator for the development of health, educational and social health systems in each country. Considering the fact that in different studies of the country there are different statistics on the prevalence of infant mortality in the intensive care unit and the general statistics on the prevalence of mortality in neonates in the country are unclear and unclear, the aim of this study was systematic review and meta-analysis for determine the prevalence of mortality in infants admitted to the intensive care unit (ICU) of hospitals in Iran.
Methods: A meta-analysis was performed for relevant articles in scientific databases including scientific information database (SID) and Magiran, ScienceDirect, Scopus, Medline (PubMed) and Google Scholar. Entrance criteria included cross-sectional studies between March 2000 to September 2018. The search process in these databases was performed using keywords: Neonatal, Intensive Care Unit, Mortality, and Iran. Non-relevant articles included review articles, interventions, cohorts and case-control studies, excluded from the study list. Heterogeneity of study was checked using I2 index and the possibility of publication bias by funnel plot and Egger test. Data were analyzed using the comprehensive meta-analysis software, version 3 (Biostat, Englewood, NJ, USA).
Results: The overall prevalence of infant mortality in ICU hospitals was 21.8% (95% CI 14.4-31.6%), the highest prevalence of infant mortality in Isfahan was 64.4% percentage (95% CI 57.5-70.9%) and the lowest mortality rate in babies in Babol's intensive care unit with 5.1% (95% CI 3.8-6.7%). The results of the study showed that the prevalence of infant mortality was significantly reduced with increasing sample size (P<0.05). Also, with an increase in years of research, the frequency of infant mortality in the intensive care unit increases, which is also statistically significant respectively (P<0.05).
Conclusion: Considering the high prevalence of infant mortality in ICU hospitals in Iran, health policy makers need to take effective measures to raise awareness of parents as well as effective measures to reduce infant mortality.

Abstract
Background: Congenital heart diseases are the second group of congenital anomalies in infants. These disorders are a major cause of death in the first year of a child's life. Early detection helps to treat these diseases better. In this study cardiology consultations of hospitalized infants in the neonatal intensive care unit were evaluated.
Methods: In this cross-sectional study, two hundred and fifty pediatric cardiology consultations conducted in Shahid Beheshti Hospital in the year 2012 were reviewed. Information such as the cause of consulting, delivery type, age of parents, relative couples, family history of congenital heart disease, maternal medications, maternal background diseases, the final diagnosis, and prognosis follow-up of the patients were recorded in a designed questionnaire. Finally, the data were entered into the SPSS software, version 16 (IBM SPSS, Armonk, NY, USA) and analyzed using descriptive statistics and chi-square test. P-value of less than 0.05 was considered significant.
Results: The mean age of the consulted neonates was 4.845±5.14 days with a gestational age of 33.933±3.65 weeks. Male sex and cesarean section were the most frequent. Fifty-six percent of consulted infants were male. The present study revealed that prematurity (76%), murmurs (30.8%), respiratory distress syndrome (14.4%) and cyanosis (13.2%) were the most common causes of the cardiac consultation seeking among infants. Seventy-six percent of infants were consulted due to prematurity. Eighty-four percent of infants had a normal conditions. Septal defects (ventricular or atrial septal defect) and patent ductus arteriosus were the most common disease diagnosed with the prevalence of 27.5 and 17.5%, respectively. There was a significant relationship between preterm labor and congenital heart disease (P<0.001). Additionally, prematurity associated with respiratory distress syndrome and using assisted reproductive techniques.
Conclusion: The higher prevalence of congenital heart disease in the present study, compared with other studies, reflects the fact that cardiology consultation based on clinical suspicion leads to the more identification of congenital heart disease that means the right referral of newborns for consultation was accompanied with a higher incidence of heart failure.

Abstract
Background: Health care associated infections (HAIs) are a class of infections that infect patients during hospital admissions and receive medical services. These infections occurs within 48 to 72 hours of admission and up to 6 weeks after discharge. Surveillance of device-associated infections (DAIs) in intensive care units (ICUs) is substantial in planning healthcare strategies. This study was conducted to determine the device-associated infections' burden and antimicrobial resistance patterns.
Methods: In this descriptive-analytic study, three common device-associated infections included central line-associated bloodstream infection (CLA-BSI), ventilator associated pneumonia (VAP), and catheter-associated urinary tract infection (CA-UTI), were assessed in intensive care units of Besat Hospital in Hamedan from April 2017 to April 2018. In order to determine the incidence of device-associated infections, the number of device-associated infection cases was calculated during the study period and divided into the number of device-days used. The device-days included all days of exposure to that device (vascular catheter, endotracheal tube (ventilator), or urinary catheter) in all patients in the study population.
Results: Out of 1806 intensive care unit admitted cases, 168 patients (9.3%) were device-associated infection with distribution of 92 cases (55%) of ventilator-associated pneumonia (VAP), 56 cases (34%) of catheter-associated urinary tract infection (CA-UTI) and 20 cases (11%) of central line-associated bloodstream infection (CL-BSI). The incidence of VAP, CA-UTI and CL-BSI was 44.7, 17.5, and 21.61 days, respectively. The most organisms were Acinetobacter (27.4%), Klebsiella (18.3%), Escherichia coli (E. coli) (15.4%). Vancomycin-resistant enterococcus (VRE) was 75%. Acinetobacter resistance to colistin and carbapenem was 16.8%. About half of Pseudomonas isolates were resistant to meropenem.
Conclusion: According to the present findings of this study, a high incidence of device-associated infections and resistant organisms in our intensive care units were documented, which represents a need to reinforce the preventive and control programs. Various results in different studies can be due to differences in the level of health care in different centers and countries.

Abstract
Background: Intravenous (IV) injection of drugs is one of the most common methods of drug prescription in hospitals, which is a complex, potentially hazardous and erroneous method; accordingly, it requires control methods to reduce the potential risks. This study focused on determining the frequency and types of different medication errors while preparing and administering mostly used IV drugs in three intensive care units (ICU) and one general department in AL-Zahra hospital, Isfahan, Iran.
Methods: This cross-sectional observational study was conducted for 6 months from September 2017 to March 2018. To determine the frequency of different medication errors, a quoting sampling method was applied to select and observe 400 cases of IV drug administrations. All nurses from any studied department were included in this study. Different stages of preparation and administration of the observed drugs were compared to an instructed checklist prepared by the clinical pharmacist.

Results: Totally, 75 nurses were recruited from ICU-1 (N=29), ICU-2 (N=18), ICU-3 (N=19), and nephrology (N=9) departments. Type of department and occupation were the influential factors on nursing errors; also, a significant relationship was found between different work shifts and the occurrence of nurses’ errors, mostly seen in the evening work shift (P=0.037). The mean of nurses’ errors in IV drug administration was not correlated with other factors including age, work history, and the number of patients managed by each one. Also, a positive correlation was found between the number of nurses in each work shift and the number of errors (P=0.008).
Conclusion: Medication errors in each stage of drug administration may lead to the hazardous clinical outcome or serious side effects such as thrombosis, infection or eventually lead to morbidity or mortality. Therefore, being aware of these errors and establishing observational policies can prevent unpleasant events related to drug administration. |

Abstract
Background: Opioid poisoning is the most common type of poisoning in intensive care units (ICUs). This group usually includes patients who have been drug abusers for a long time and now require hospitalization either because of acute overdose or due to side effects of routine opioid use. This study aimed to compare the severity and prognosis of patients using common mortality predictors Sequential Organ Failure Assessment (SOFA), Simplified Acute Physiology Score (SAPS II), Acute Physiology And Chronic Health Evaluation (APACHE II, APACHE IV) on different days of hospitalization.
Methods: This cross-sectional study was performed on all patients with opioid poisoning admitted to the ICU, Imam Reza Hospital, Mashhad, Iran, from the beginning of April 2016 to March 2017 (Persian Calendar). For all poisoned patients enrolled in the study, the four mortality predicting tools were filled daily in the first three days of hospitalization and then every other day until discharge from the ICU or patient's death.

Results: Overall, 57 patients were evaluated of whom 72% (41 patients) were male. The mean age was 49.9±19.8 (median 53, range 18-94) years. The mean length of stay in the ICU was 13.5±17.5 (median 7, range: 75-75) days. The mortality rate was 17.5% (10 patients). The scores of SOFA, SAPS II, APACHE II, and APACHE IV were significantly higher in deceased patients than in discharged ones. The highest diagnostic accuracy (area under the curve) for all four predicting tools was observed in the second week of hospitalization. On the other hand, SAPS II (74%) on the first day, APACHE-II (76%) on the second day, APACHE-II (82%) on the third day, SOFA (77%) on day 4-5, and SAPS II (82%) on day 6-7 had the highest diagnostic accuracy.
Conclusion: In the present study scores of all four mortality predicting tools at admission were significantly associated with mortality. The accuracy of SAPS II, APACHE IV, and APACHE II are appropriate for estimating prognosis, especially after the second week of admission. |

Abstract
Background: Because deep vein thrombosis (DVT) is one of the most common problems in the intensive care unit, it may lead to complecating the patient's general condition. This study aimed to investigate the predictive factors of DVT in patients admitted to the intensive care unit (ICU) of Amin hospital in Isfahan.
Methods: In this retrospective study, all the records of patients admitted to the ICU ward of Amin Hospital located in Esfahan, from April 2015 to March 2018, were investigated and from all patients with DVT, 20 records were extracted and 40 cases of patients without DVT were also randomly selected. Information such as age, sex, Wells score, Apache score, nutritional status, clinical parameters, cause of hospitalization, length of stay, ICU induced disease and treatment were extracted from these records and compared between both groups with and without DVT.

|
Results: From 2000 patients admitted to the ICU ward, 20 cases were developed DVT. The age of patients in the DVT group was significantly higher (P=0.008). Factors such as increased Wells score, increased length of stay in the ICU, having ICU induced internal diseases and pneumonia increased the chance of DVT incidence as 18.75, 1.92 and 2.75 and 2.28 times, respectively and the increase of potassium level and use of heparin bandage for treatment reduced the chance of DVT by 2.31 and 2.55 times, respectively (P<0.05).
|
Conclusion: In the general intensive care unit, the incidence of deep vein thrombosis was higher in internal ward patients. Pneumonia was the most common disease associated with deep vein thrombosis and the risk of deep vein thrombosis was higher in the anemic patient. Patients with upper limited normal levels of potassium were less likely to develop deep vein thrombosis. It seems that potassium in the upper limit of normal reference can play a protective role against deep vein thrombosis. Further studies with larger sample sizes are suggested.

Abstract
Background: Early outcome prediction of hospitalized patients is critical because the intensivists are constantly striving to improve patients' survival by taking effective medical decisions about ill patients in Intensive Care Units (ICUs). Despite rapid progress in medical treatments and intensive care technology, the analysis of outcomes, including mortality prediction, has been a challenge in ICUs. Hence, this study aims to predict the mortality of patients admitted to ICUs using data mining techniques.
Methods: In this study, among the cases of patients who were admitted to ICUs of the Rasoul Akram and Firoozgar hospitals of Tehran City, Iran, from December 2017 to March 2018, the first 24 hours of the ICUs admission data of 874 cases were gathered. A new model based on the standard methodology CRISP was developed. In the modeling section, two well-known data mining techniques called artificial neural network (ANN), K nearest neighbor (KNN) and decision tree (DT) were used. WEKA 3.9.2 open-source software was implemented for data analysis. Finally, according to the accuracy, sensitivity, specificity criteria and AUC-ROC Curve, the superior model was introduced.
Results: Based on the WEKA results, 19 variables had the most impact on the mortality prediction of patients admitted to ICUs including Glasgow Coma Scale (GCS), mechanical ventilation, surgical service at ICUs admission, gender, temperature, serum creatinine, diabetes, Blood urea nitrogen (BUN), age, addiction, International Normalized Ratio (INR), PH, Partial Thromboplastin Time (PTT), albumin, hemoglobin, glucose, pulse rate, hematocrit (HCT), PO2. Based on the created models, some rules have been extracted which can be used as a pattern to predict the probability of mortality. Although the AUC of the three models was acceptable (KNN 81.5%, ANN 77.5% and DT 74.3%), but the accuracy of decision tree J48 (74.2%) was higher.

Abstract
Background: The decision to extubate the patient is crucial and challenging. The use of corticosteroids to reduce airway edema and extubation failure in intensive care patients is debatable.
Methods: In an observational prospective cohort study from April 2021 to July 2021, 110 patients undergoing head and neck surgery at Imam Khomeini Hospital's special wards were enrolled. Inclusion criteria: Patients undergoing head and neck surgery. Exclusion criteria: previous corticosteroid use, presence of tracheostomy tube, history of head and neck surgery. The intervention group (n=55) received intravenous dexamethasone 8 mg three times a day for the first 24 hours and 4 mg twice a day for the next 24 hours. The control group did not receive any corticosteroids (n=55). All the patients were weaned with the same protocol, including pressure support ventilation with pressure support 6-8 cm H20 and PEEP <5 cm H2o and FIO2 ≤0.4 for 1-2 hours without respiratory distress, hypoxia, tachycardia, and diaphoresis. Before extubation, the cuff leak test was done for all the patients with the cut-off point of 110 ml. The Chi-square or Fisher's exact test was performed for categorical variables, and a t-test was used to describe the quantitative variables. P-values less than 0.05 were considered statistically significant.

Results: The mean age was 52.1±14.1, and there was no difference between the two groups. Demographic characteristics, including sex, body mass index, duration of surgery, kind of intubation, and Acute Physiology and Chronic Health Evaluation (APACHE) II score, were not significantly different. The length of stay in the intensive care unit in the dexamethasone group was significantly longer than the control group (104 vs. 79-hour, P=0.001, CI 95%: 10.995-40.878). The rate of failure in extubation and postoperative stridor was not significantly different between the two groups (P=0.237).
Conclusion: Dexamethasone usage seems not to be effective in reducing airway edema, and its routine use is not recommended in reducing stridor after endotracheal tube removal. |

Abstract
Background: Coronavirus in 2019 was recognized as one of the leading causes of death worldwide. According to reports, the mortality rate in people who need mechanical ventilation varies from 50 to 97 percent. The aim of this study was to evaluate the outcome of Covid-19 disease based on different characteristics in patients and mechanically ventilated variables.
Methods: This descriptive-analytical study was conducted on 160 patients with a definite diagnosis of Covid-19 who were under mechanical ventilation and admitted to the intensive care unit of Alzahra Hospital in Isfahan from March 2020 to March 2021. Data was collected by checklist. The checklist included demographic information, including age, gender, as well as information such as underlying diseases, disease outcome, length of hospitalization, etc. After collecting the data, they were analyzed in SPSS software version 22 and at a significance level of less than 0.05.

Results: In this study, the overall mortality rate among mechanically ventilated patients was 62.5%. The mean age of patients was 69.99±17.87 years and the mean duration of hospitalization in surviving patients was 15.47±11.73 days and for deceased ones was 55.21±69.14 days. The mean age of the deceased group (65.71±16.59) was significantly higher than the surviving group 53±21.17 was (P=0.0001). The length of hospital stay in the deceased group was significantly longer than the surviving group (P=0.005). As a result, ventilator mode and inotropic agent intake during treatment increased the chance of mortality in patients under mechanical ventilation (P=0.001). There was a significant relationship between underlying diseases of hypertension, kidney disease and autoimmune disease with mortality in patients (P<0.05).
Conclusion: Various factors including the length of stay in the hospital, comorbidities such as hypertension, renal disease and autoimmunity may affect the outcome of critically ill ICU patients under mechanical ventilation. Patients who require long-term invasive ventilation and the use of inotropic drugs to maintain their cardiovascular status while hospitalized in the ICU are at higher risk for mortality. |

Results: In this study, the median of patients age was 67 and 10 (58.82%) of them were women. The median systolic and diastolic blood pressures were 170 and 95 mmHg on admission. 4(23.53%) subjects were not aware of the disease. Out of 13 people who were aware of their hypertension, 11(64.71%) were under the supervision of a physician. However, 7(63.64%) of the subjects, despite being under the supervision of a physician and acceptable drug adherence, did not have controlled blood pressure and expired.
Conclusion: This study is a warning for patients and health care providers to pay more attention to blood pressure control. Furthermore, educating the community as well as medical staff about the importance of timely diagnosis and accurate treatment of hypertension is highly recommended. |

Abstract
Background: Prolonged stay in intensive care unit (ICU) can worsen the patient's prognosis and represents a significant economic burden. Previous studies have reported the effectiveness of early mobilization in reducing length of stay in ICUs for adult patients; However, conflicting results have been reported regarding its effects on pediatric patients. Therefore, this research aimed to investigate the impact of early mobilization on the length of stay in the pediatric intensive care unit (PICU) in ventilated children.
Methods: This pilot quasi-experimental study was conducted on 60 children admitted to the Children's Medical Center hospital from March 2020 to June 2021. For the control group, routine care (standard physiotherapy) was started on the second day of intubation and continued until discharge from the intensive care unit. In this study, we used an early mobilization protocol including active and passive exercises. The intervention was implemented by Pediatric intensive care unit nurses under supervision of a pediatric critical care fellowship physician. In the intervention group, passive exercises were started on the second day of intubation. At each shift, the nurses check the level of sedation and presence of delirium in the patients using the Richmond Agitation-Sedation Scale and the Cornell Assessment of Pediatric Delirium questionnaire. If the results showed that the sedation was not deep and delirium was not present, then active exercises were initiated. If the child did not achieve an adequate score indicating the absence of deep sedation and delirium, the patient remained in the passive exercise phase. The length of stay was recorded based on the patients' records. Descriptive and inferential statistics were used for data analysis using SPSS version 23.

Abstract
Background: This study aimed to evaluate serum amylase levels in hospitalized COVID-19 patients and investigate its association with disease prognosis. Elevated serum amylase levels have been reported in some COVID-19 patients, particularly in severe cases. This increase may indicate pancreatic involvement (pancreatitis) due to viral infection. This cross-sectional study aimed to evaluate the role of serum amylase levels as a prognostic marker in COVID-19 patients.
Methods: This descriptive cross-sectional study was conducted on 150 hospitalized patients with confirmed COVID-19 at Baharloo Hospital, Tehran, over a one-year period (July 2021–July 2022). The results showed that 20% of patients (30 out of 150) had elevated serum amylase levels. Patients with high amylase levels had significantly longer hospital stays (mean 14 days vs. 8 days) and higher mortality rates (15% vs. 5%). Additionally, these patients were more likely to require intensive care (25% vs. 10%). Statistical analysis revealed that elevated serum amylase levels were independently associated with poorer clinical outcomes.
Results: These results have important clinical implications for patient management. Routine measurement of serum amylase at admission could help identify high-risk patients who may benefit from closer monitoring and early intervention. Further research is needed to determine whether specific treatments for pancreatic involvement could improve outcomes in these patients.
Conclusion: These findings suggest that measuring serum amylase levels at admission can serve as a simple and accessible marker for identifying high-risk patients. Elevated amylase in COVID-19 patients is an important biological indicator of multi-organ involvement (pancreas and kidney) and severe inflammation, which is associated with worse prognosis and higher mortality. Monitoring this marker may aid clinical decision-making and improve patient outcomes

Abstract
Background: Aspiration pneumonia is a significant and potentially preventable cause of morbidity and mortality in critically ill ICU patients. Prophylactic pharmacological interventions, particularly antiemetics like metoclopramide (a prokinetic agent) and ondansetron (a 5-HT3 receptor antagonist), are commonly employed to reduce gastric aspiration and subsequent pneumonia. Despite their widespread use, comparative efficacy data remains limited. This randomized controlled trial was specifically designed to rigorously compare the effectiveness of these two distinct antiemetic strategies in preventing aspiration pneumonia among high-risk, mechanically ventilated patients, aiming to provide evidence-based guidance for clinical practice.
Methods: This double-blind randomized clinical trial involved 116 individuals admitted to the ICU at Shahid Mohammadi Hospital, Bandar Abbas from March 2024 to March 2025. Subjects were randomly assigned to metoclopramide or ondansetron groups. Enrollment criteria consisted of patients between 17 and 70 years old in the ICU requiring intubation and mechanical ventilation. Monitoring continued for 72 hours, with evaluation utilizing the Clinical Pulmonary Infection Score (CPIS), chest X-ray (CXR) results, and physical assessments. Data were analyzed with SPSS version 21 employing descriptive statistics (mean, standard deviation, percentage, frequency) and inferential tests with significance set at P<0.05.
Results: Chi-square analysis indicated no statistically significant gender difference between groups (P=0.947). Mean age was 30.6±10.5 years for metoclopramide recipients and 32.9±6.12 years for ondansetron recipients. Further analysis revealed no significant differences in age or BMI between cohorts. No significant difference emerged between metoclopramide and ondansetron groups regarding aspiration pneumonia occurrence, with similar incidence rates in both arms. Multiple logistic regression demonstrated that statistically, no variables influenced aspiration pneumonia development.
Conclusion: The results of this randomized trial clearly demonstrate no statistically significant difference in efficacy between metoclopramide and ondansetron for preventing aspiration pneumonia in intubated ICU patients. Both agents showed comparable effectiveness in our study population, suggesting that either drug represents a clinically acceptable prophylactic option. This finding provides clinicians with valuable therapeutic flexibility based on individual patient characteristics, drug availability, and cost considerations. However, further multicenter studies with larger sample sizes are recommended to confirm these findings across diverse patient populations and settings.

Abstract
Background: Patients undergoing mechanical ventilation in the intensive care unit (ICU) are at higher risk for delirium. The present study aimed to compare the frequency of delirium in patients requiring anesthesia receiving the Presedex and fentanyl regimen with the midazolam and fentanyl regimen in the intensive care unit (ICU).
Methods: This historical cohort study was conducted on all patients hospitalized in the intensive care unit of Kowsar Hospital in sanandaj from May 2018 to December 2024 as a census with a sample size of 40 people in each group. Delirium and restlessness were assessed based on RASS criteria and the GCS scale was used to assess the level of consciousness of the patients. The data were entered into SPSS 24 software and a significance level of less than 5% was considered.
Results: The average age of the patients in Perdex, fentanyl, midazolam, and fentanyl regimens was 41.52 and 34.05 years, respectively. 53(66.3%) patients were male and the rest were female. The GCS score in the Presdex and Fentanyl group was 14(35%) and the Midazolam and Fentanyl group was 4(10%) with a level of consciousness above 7. The RASS score (5 patients in the Presdex and fentanyl group (12.5%) and the midazolam and fentanyl group (36 patients in the midazolam and fentanyl group (90%) had an anxiety score of zero or higher) was 0. The frequency of delirium based on CAM-ICU criteria in the Presdex and fentanyl group was 27(67.5%) mild delirium and 13(32.5%) moderate delirium, but in the midazolam and fentanyl group, 6(15%) mild delirium, 24(60%) moderate delirium, and 10(25%) severe delirium were present, and this difference was significant in the results of level of consciousness and restlessness and incidence of delirium (P=0.000).
Conclusion: The results showed that the use of Presedex and fentanyl would be more effective in reducing the incidence of delirium, and the use of this drug could be effective.
