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: 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.
