Volume 55, Issue 6 (8-1997)
Abstract
Sixty pregnant women with the gestational age of 6-14 weeks who met the following criteria were selected: 1) Presence of nausea and vomiting. 2) Absence of other medical conditions that cause nausea and vomiting. 3) Negative history of medical treatment for at last three days prior to admission. 4) Negative for threatened abortion, molar and twin pregnancy. Cases were randomly divided into two groups. Mean age of the cases was 25.16 y (range: 16-37 y) and not significantly different in the two groups. The two groups were also similar in gestational age, severity of nausea and vomiting, number of previous pregnancies and abortions, profession, working inside or outside the house, family income and education of patients and their spouses. In one group, Pe6 point of acupuncture was stimulated by TENS (once every 2 hours, 10 minutes each time, from the time of awakening). The other group received placebo. Both groups were hospitalized for 48 hours, and were evaluated for severity of nausea and vomiting, apetite, frequency of vomiting and VAS at their worst day, 24 hours prior to admission and 24 and 48 hours after admission. The two groups were similar in frequency of vomiting, VAS, appetite, and severity of nausea 24 hours prior to admission, and the worst degree of nausea and vomiting. However, a significant difference was observed in the severity of nausea and vomiting 24 and 48 hours after the adminission between TENS and placebo (P=0.000). In the group who received TENS, 24 cases (86.7%) reported improvement (compared to 23.3% in the control group). Of all the cases, 81.6% had received prior medication, only 18.3% of the latter reported improvement with medication. Level of VAS in the groups with severe and mild to moderate nausea and vomiting was not significantly different in the first and second days of admission. Fifteen percent of the cases reported a transient cutaneous rash. Five cases were hospitalized more than once. Of the cases who reported improvement with TENS, 5% had improved after two stimulations, and 47% reported a relapse of symptoms in less than 24 hours after cessation of TENS. In one of the cases who were re-admitted, TENS did not result in alleviation of nausea and vomiting, and 56.6% of all the cases suggested to use TENS at home, 45% were attracted to TENS by commercial advertisements. Disscusion: Stimulation of Pe6 (Neiguan) point alleviates the nausea and vomiting of pregnancy.

Abstract
Postoperative nausea and vomiting is a common complication that all anesthesiologist are familiar with the problems of its consequences. Although continued research on the recognition of factors affecting the incidence of PONV is being done but they are not sufficient and the need for research along with advances in anesthesiology and newer drugs are considered. In this prospective cohort study 400 children of 3 to 12 age who has been operated for general surgery (other than eye, thorax and upper abdomen) and orthopedic surgery in the Imam Khomeini and Children Medical Center Hospital has been evaluated. Of these, 200 children who had smoking parent and according to definition were passive smokers and the other 200 children had no smoking parents. Both the groups were matched for sex, age, and type of operation. With the analysis of data we noted that the incidence of PONV in both groups was 19.5 and there was no significant difference between the two groups. (Passive smoker 19 percent and non-passive smoker 20 percent). We also noted a relation between the duration and the incidence of PONV. So operation with more than 2 hours had higher incidence of PONV. There was also positive relation between PONV and controlled ventilation. However, there was no significant difference as the sex and type of operation was concerned. In conclusion, children of smoker parents suffer more PONV than children of non-smoker parents if operation takes longer than two hours or the patient is mechanically ventilated during operation.

Abstract

Background : Chemotherapy-induced nausea (CIN) in the anticipatory and acute phase is the most common side effect in cancer therapy. The purpose of this study was to investigate the effect of ginger capsules on the alleviation of this problem.

Methods : This randomized, double-blind, placebo-controlled clinical trial was performed on 80 women with breast cancer between August till December 2009 in Imam Khomeini Hospital, Tehran, Iran. These patients underwent one-day chemotherapy regime and suffering from chemotherapy-induced nausea. After obtaining written consent, samples were randomly assigned into intervention and control groups. Two groups were matched based on the age and emetic effects of chemotherapy drugs used. The intervention group received ginger capsules (250 mg, orally) four times a day (1 gr/d) and the same samples from the placebo group received starch capsules (250 mg, orally) for three days before to three days after chemotherapy. To measure the effect of capsules a three-part questionnaire was used, so the samples filled every night out these tools. After collecting the information, the gathered data were analyzed by statistical tests like Fisher’s exact, Kruskal-Wallis and Chi-square using version 8 of STATA software.

Results : The mean ± SD of age in the intervention and placebo groups were 41.8 ± 8.4 and 45.1 ± 10 years, respectively. Results indicated that the severity and number of nausea in the anticipatory phase were significantly lower in the ginger group compared with placebo group (P=0.0008, P=0.0007, respectively). Also, the intensity (P=0.0001) and number (P=0.0001) of nausea in the acute phase were significantly lower in the ginger group. On the other hand, taking ginger capsules compared with placebo did not result in any major complications.

Conclusion: Consuming ginger root powder capsules (1 gr/d) from three days before chemotherapy till three days after it in combination with the standard anti-emetic regimen can help to reduce the anticipatory and acute nausea.

Abstract
Background: Nausea and vomiting is one of the most important complications in chemotherapy. Serotonin and dopamine are important neurotransmitters in nausea and vomiting. It seems that oxygen therapy and increase oxygen saturation can cause decrease these neurotransmitters. The aim of this study was to investigate the relationship between arterial oxygen saturation (SaO2) of patients and chemotherapy-induced nausea and vomiting. Methods: A descriptive-analytical study was performed in Koosar Hospital in Semnan, Iran, from 19 September 2013 to 25 April. At first, SaO2 of 30 patients in three periods (pre, during and post chemotherapy) were measured. Severity of nausea and vomiting in three days after chemotherapy was measured with an index of nausea, vomiting and retching (Rhodes Index). Also during chemotherapy, anxiety and depression of patients was measured with Hospital Anxiety and Depression Scale (HADS). Results: In this study thirty patients were evaluated. Most of them were women (66%) with mean age of 55.07±11.9 years old. The most common cancer in patients was breast cancer (46.7%). Mean of SaO2 was 92.1%±3.4 that was not significant difference during the chemotherapy. Mean of nausea and vomiting severity in first day of chemotherapy was (3.27±5.5), in second day was (4.5±6.2) and in third day was (7.2±8.7). The Pearson correlation coefficient did not show the relationship between oxygen saturation with severity of nausea and vomiting (P>0.05). Although severity of anxiety of patients was significant relationship with nausea and vomiting in third day (P=0.03). Conclusion: In this study there was no significant relationship between oxygen saturation and severity of nausea and vomiting, but anxiety of patients was related to nausea and vomiting in third day. Chemotherapy-induced nausea and vomiting was more common in third day and it seems that further research is needed for relationship between oxygen saturation and nausea and vomiting in third day of treatment.

Volume 73, Issue 3 (6-2015)
Abstract
Background: Hyperemesis gravidarum (HG) starts between four and seven weeks after the first day of the last period, and ends at twenty weeks of pregnancy. The etiology of HG, is unknown. Recent studies worldwide show the Helicobacter pylori (H. pylori) infection as a possible cause of the severe nausea and vomiting in pregnancy, recent studies showed H. pylori to have a role in occurrence of it during pregnancy. The current study assessed the immunoglobulin G (IgG) and immunoglobulin M (IgM) titer to H. pylori in pregnant women with HG. Methods: This is a case-control study of the pregnant patients of a gynecologist's office in the Marvdasht city from April to September 2013. One hundred and twenty three patients were randomly chosen based on their conditions and were divided into two groups (case n1= sixty three and control n0= sixty). The IgG and IgM titers against H. pylori were measured by ELISA method. Data analysis was performed using Chi-square test, Mann-Whitney U-test, and T-test in SPSS software, version 20 (SPSS, Inc., Chicago, IL, USA). The significant level of the test was considered (P= 0.05). Results: Totally, 123 pregnant women were evaluated 63 women with hypermesis gravidarum and 60 without HG. Forty nine women out of 63 in HG group and 48 women in the control group were IgG positive for H. pylori. Also, mean serum level of IgG was 51.6 in the HG group (P= 0.685). Twelve women out of 63 in HG group and 20 women in the control group were IgM positive for HP. Also, mean serum level of IgM was 27.7 in the HG group (P= 0.675) Except for the mother's blood type, there were no other statistically significant differences found between the two types of antibodies against H. pylori. Conclusion: There is no relationship between helicobacter pylori and hyperemesis gravidarum in pregnant woman. Considering the high prevalence of H. pylori infection in our country, there is a need for studies with more samples and more diagnostic methods.

Abstract
Background: Nausea and vomiting is one of the most common complications after the strabismus surgery. In this study, we evaluated the efficacy of atropine versus ondansetron administration on the incidence of postoperative nausea and vomiting and duration of recovery stay in patients undergoing this procedure.
Methods: In this case-control study, 90 patients between 3 to 30 years old who were candidates for elective strabismus surgery in Farabi Eye Hospital, Tehran University of Medical Sciences, Tehran, Iran, from February to April 2019, were randomly divided into three groups (placebo, ondansetron and atropine group). Patients who had taken hypnotic drugs while entering the operating room were excluded. In all patients, after arriving into the operating room and installation of standard monitoring equipment and peripheral vein implantation, anesthesia was induced by receiving 0.05 mg/kg midazolam, fentanyl 1 μg/kg and propofol 2.5 mg/kg. After induction of anesthesia, placebo group was compared with ondansetron group and atropine group that received 0.1 mg/kg ondansetron and 30 µg/kg atropine, respectively. The rate of postoperative nausea and vomiting, duration of recovery stay and satisfaction of recovery nurses were recorded and compared between groups.
Results: There was no statistically significant difference between the three groups in terms of mean age, weight, and gender. It seems that group matching is appropriate and there are no confounding factors for demographic variables. Administration of atropine and ondansetron significantly reduces the incidence of nausea and vomiting postoperatively and in recovery. There was no significant difference in the incidence of nausea and vomiting between the atropine and ondansetron groups. Duration of recovery stay was decreased after ondansetron and atropine administration versus control group. Postoperative laryngospasm and bronchospasm were not observed in any of the three groups after surgery and at the time of recovery. The satisfaction of recovery nurses in both atropine and ondansetron groups were higher than control group.
Conclusion: It seems that the administration of atropine as much as ondansetron can be effective in reducing the incidence of postoperative nausea and vomiting and the length of recovery stay in patients who undergoing strabismus surgery.

Volume 80, Issue 9 (12-2022)
Abstract

Background: Migraine is a recurrent disease which its definitive mechanism is still unknown. Thus mitochondrial dysfunction and neurovascular damage are two hypothetical underlying mechanisms for migraine headaches. The effectiveness of some possibly effective compounds such a CoQ10 has been studied. In this study, we evaluated the efficacy of coenzyme Q10 in migraine headache prophylaxis.
Methods: This study was performed as a double-blinded randomized clinical trial on 112 patients with a diagnosis of migraine who were referred to the Neurology Clinic of Imam Reza Hospital in Kermanshah from March to September 2018. Then the patients were randomly divided into two equal groups (control and intervention). Both groups received propranolol 20 mg twice daily (totally 40 mg/d). The intervention group was treated by CoQ10 60 mg once daily, additionally. Finally, the quantitative and qualitative characteristics of migraine headaches such as nausea and vomiting, photophobia, phonophobia, severity, frequency and duration of attacks were evaluated by Student's t-test, Mann-Whitney U test and Wilcoxon tests.
Results: At the end, it was concluded that CoQ10 supplement of 60 mg daily with propranolol 40 mg daily in patients with migraine headaches improves symptoms more than receiving propranolol 40 mg alone. The results also showed that in the intervention group, nausea and vomiting, photophobia and the severity of headache in patients significantly improved compared to the control group (P values of 0.001, 0.114 and 0.001, respectively). However, the symptoms of phonophobia, frequency and duration of headache attack in the intervention group were not significantly different from the control group (P values were 0.062, 0.853 and 0.106, respectively).
Conclusion: In conclusion considering the main goal of this study, consumption of CoQ10 60 mg daily with propranolol 40 mg daily significantly improves symptoms such as nausea and vomiting, photophobia and severe headache compared to propranolol 40 mg daily. In conclusion, CoQ10 is a suitable choice in patients who do not respond adequately to the standard drug regimen.

Volume 80, Issue 11 (2-2023)
Abstract
Background: In this study, the effect of intravenous dexamethasone on pain, nausea and vomiting after laparoscopic ovarian surgery was investigated.
Methods: This randomized clinical trial was conducted from June 2019 to March 2019 on patients undergoing laparoscopic ovarian cystectomy in Beheshti Hospital, Isfahan. In this study, 88 patients aged 18 to 45 years were included in the study. Patients were randomly divided into two groups receiving dexamethasone (D) and normal saline (S). Two minutes before induction of anesthesia, the first group received 8 mg (2 ml) of dexamethasone and the second group received normal saline (2 ml). The duration of surgery and stay in recovery, the frequency of pain and nausea and vomiting, the need for analgesic and anti-nausea drugs, and the cardiovascular response during the study were evaluated and recorded.
Results:  No significant difference was seen in terms of demographic characteristics between the two groups (P>0.05). The frequency of pain during recovery (P=0.4) was not significantly different between the two groups, but at 2 hours (P=0.005), 12 hours (P<0.001) and 24 hours after the operation (P=0.005) (P=0) was significantly lower than S group. The frequency of nausea in group D during recovery (P=0.003), 2 hours later (P<0.001), and 12 hours (P=0.002) was significantly lower than group S, but 24 hours after the surgery, there was no significant difference between the two groups (P=0.15). During recovery, there was no vomiting in both groups (P=1), the frequency of vomiting in 2 hours (P=0.003), 12 hours (P<0.002) and 24 hours after the operation (P=0.48) in group D was lower than S. At the time of the study, the dose of diclofenac and metoclopramide received in group D patients was lower than group S. There was no significant difference in cardiovascular response between the two groups during the study (P>0.05).
Conclusion: Dexamethasone with a dose of 8 mg before induction of anesthesia can be effective in reducing pain, nausea and vomiting after laparoscopic ovarian surgery and reducing the need for analgesics and anti-nausea drugs.

Seyedeh Fatemeh Hosseini Nejad , Mahshid Vaziri, Ahmad Reza Mohtadi, Elham Kargar Zadeh , Mohammad Pakzadi,
Volume 82, Issue 3 (6-2024)
Abstract
Background: Postoperative nausea and vomiting (PONV) is a common challenge in cesarean surgeries, on the other hand, the use of dexamethasone has been proposed as an effective prophylaxis in the management of these complications. This study evaluated the effect of dexamethasone in reducing PONV.
Methods: This study was conducted as a randomized and double-blind clinical trial from April 2022 to September 2023 at Razi Hospital of Jundishapur University of Medical Sciences, Ahvaz. Elective cesarean section patients under spinal anesthesia were divided into two groups of 30 people. In this research, there were two groups: a group that received 0.1 mg/kg dexamethasone (Iran company) and a placebo group that received normal saline. The injections were done before the start of anesthesia, and both groups had received 500 cc of normal saline serum before drug injection. During the surgery and after that at specific time intervals, parameters such as blood pressure, heart rate, and the occurrence of nausea and vomiting were recorded through the V&N scoring table and shivering through the shivering scoring table. Recorded 1/2/4/6/12 after surgery.
Results: In this study the investigated variable is postoperative nausea and vomiting (PONV), since the investigated variable is a qualitative/nominal variable, to calculate the sample size from the formula P1- P2 ∕√P(1-P) used. The significance level of the tests is considered to be less than 0.05 and data analysis was done with SPSS type 23 software. Although no significant difference was observed between dexamethasone and placebo in the first hour after the operation, in the following hours, dexamethasone significantly reduced nausea and vomiting, on the other hand, heart rate and blood pressure decreased faster in the groups receiving dexamethasone.
Conclusion: Dexamethasone is significantly effective in reducing nausea and vomiting after cesarean surgery. It also has a positive role in reducing the heart rate and blood pressure and This drug is particularly effective in controlling complications after spinal anesthesia after the operation.

Volume 83, Issue 1 (4-2025)
Abstract
Background: Spinal anesthesia is a common method for elective cesarean sections; however, complications such as shivering and nausea may affect postoperative recovery quality. Bupivacaine is a standard drug used in this procedure, but its combination with opioids like sufentanil may have beneficial effects in reducing these complications. This study aimed to compare the incidence of shivering and nausea in women undergoing elective cesarean section who received either bupivacaine alone or a bupivacaine-sufentanil combination.
Methods: The present study was a double-blind randomized clinical trial conducted over a 6-month period from April 2021 to October 2021 on 30 patients undergoing elective cesarean section with spinal anesthesia at Motahari Hospital in Jahrom city. Patients were randomly assigned using a random number table into two groups: bupivacaine alone and bupivacaine-sufentanil combination. The frequency of nausea, vomiting, and shivering was recorded at different time points: before spinal anesthesia, after spinal anesthesia, 3 minutes before delivery, immediately after delivery, at 15, 30, and 45 minutes, upon recovery room admission, and upon discharge from recovery. The data analysis was performed using descriptive statistics indicators (frequency, percentage, mean, and standard deviation) and inferential statistical tests (t-test, Mann-Whitney, chi-square and Friedman) using SPSS software version 21. A significance level of p < 0.05 was considered.
Results: In the bupivacaine-sufentanil group, the highest frequency of shivering occurred at 30 minutes post-spinal anesthesia (20%) and upon recovery room admission (26.7%). In the bupivacaine-alone group, the highest frequency was observed upon recovery room admission (33.3%) and at discharge from recovery (26.7%). The highest nausea frequency was 33.3% in the bupivacaine-sufentanil group and 40% in the bupivacaine group at 3 minutes before delivery. However, no statistically significant difference was found between the two groups at different time points.
Conclusion: The present study showed that adding low-dose sufentanil to bupivacaine in spinal anesthesia protocols, while potentially having minor clinical effects on certain complications, did not lead to a significant difference in the incidence of shivering and nausea. Therefore, for more precise clinical decision-making regarding drug combinations in regional anesthesia, further studies with larger sample sizes and different drug dosages are recommended.
