The objectives of this analytical-descriptive study were determinig the incidence of nosocomial pneumonia as a result of aspiration among the hospitalized patients in the intensive care units of Tehran university of medical sciences in 1999.For collecting data, the applied instruments consisted of: Glucose oxidase tape, thermometers, blood tests, chest radiography, culture from endotracheal secretions and checklists.The samples, consisting 80 patients, were assigned into 2 groups according to the day starting gavage: the first group included 50 patients from the first day connecting to ventilator and second group included 30 patients from the second day connecting to ventilator.Following nearly 5 months of sampling incidence of nosocomial pneumonia resulting from aspiration estimated to 31.2%with an interval estimation of 21%<<41 %. Moreover, incidence of nosocomial pneumonia lacking aspiration estimated to 18.7% with an interval estimation of 1 l%<<27%.The results indicated that remaining the nosogastric tube and early gavaging of the patients under ventilation can be effective risk factors in the incidence of nosocomial pneumonia. Furthermore, the most pulmonary infiltration was happened in the upper lobe of the right pulmonary. Therefore, it could be supposed that the patients during aspiration had been mainly slept on their back.

Background & Objective: The mortality rate of pneumonia caused by mechanical ventilation is about %25-30. Pneumonia prolongs length of stay in hospital to more than 13 days. There are various approaches to decrease rate of pneumonia in medical wards. The aim of this study was to assess the effect of planned passive respiratory exercise on prevention of pneumonia in coma patients undergo ventilation.

Methods & Materials: In this quasi-experimental study, 76 patients were assigned into two experimental and control groups. The control group (n=38) received usual care in the ICU. The experiment group (n=38) received planned respiratory care within six days. The procedure was done in five minutes/six hours for a three day period and then in 10 minutes/six hours for the next three days. Laboratory tests were done before the intervention and in the third and sixth days of the intervention. The respiratory care planning included respiratory passive exercises along with the common respiratory care.

Results: The results indicated that there were significant differences in the results of lab tests between two groups after the intervention (P<0.0001).

Conclusion: The results of this study showed that planned respiratory care had positive effect on prevention of respiratory infection in coma patients.

  Background & Aim: The ventilator associated pneumonia is a common problem in critical care units. It is associated with increased mortality, cost and length of stay. Nurses have great role in preventing the ventilator associated pneumonia. The aim of this study was to assess nurses' performance in prevention of ventilator associated pneumonia .

  Methods & Materials: In this descriptive study, 110 nurses working in selected hospitals affiliated to Tehran University of Medical Sciences were selected using convenience sampling method. A 32-item observational checklist was provided based on the ventilator associated pneumonia prevention guideline. The nurses' performance was observed three times. Data were analyzed using descriptive statistics in the SPSS-16 . 

  Results: This study showed that the mean score of the nurses' prevention was 46.8±5.79. Most of the nurses (66.4%) had poor performance and 36.6% had relatively good performance. There were no nurses with favorable performance in the prevention of ventilator associated pneumonia. The highest score was in contact precaution (72±9.67) and the lowest score was in mouth hygiene (18.78 ± 17.4) .

  Conclusion: The majority of nurses had poor performance in prevention of ventilator associated pneumonia. More attention should be paid for planning appropriate training programs for nurses and giving adequate facilities to improve health care quality .

Background & Aim: Poor oral care for the ventilated patients in intensive care units (ICU) can result in the accumulation of pathogens and respiratory infections. In this regard, in addition to the chemical methods, a mechanical method has been recommended to be added. However, concerning its effect on pneumonia, different findings have been reported. Therefore, this study was conducted to compare the effects of chlorhexidine solution with or without toothbrushing on the development of ventilator-associated pneumonia among patients in ICUs.

Methods & Materials: This was a single-blind, randomized controlled clinical trial conducted in two selected hospitals of Ahvaz city in 2014. A convenience sample of 68 ventilated patients was randomly allocated to the toothbrush group (34 patients) or the gauze swab group (34 patients) using R software. Both groups received 0.2% Chlorhexidine solution. The intervention was performed in both groups for 3 minutes twice a day for five days. At the end of the fifth day, the development of pneumonia was assessed using the Clinical Pulmonary Infection Score (CPIS). Data were analyzed by Chi-square and t-independent test through SPSS v.16.

Results: The two groups were similar for age, sex, cause of admission, level of consciousness, medication and tobacco use. The majority of patients (58.8%) were diagnosed with pneumonia (Group A: 55.9% and Group B: 61.8%). The Chi-square test showed no significant difference between the two groups for the development of pneumonia (P>0.05).

Conclusion: The use of Chlorhexidine solution with toothbrushing compared to using Chlorhexidine with swab could not reduce the development of pneumonia. However, due to its importance, further research is needed in this regard.
