Effect of oral gastric tube insertion during anesthesia induction on nausea and vomiting of adenotonsillectomized patients

Nausea and vomiting are from the most common complications of surgery during recovery. Adenotonsillectomy is a common surgery among children, which can be followed by some complications such as nausea, vomiting, bleeding, and even death in some cases. There are some medical and nonmedical remedies to decrease nausea and vomiting. A nonmedical therapeutic procedure is reduction of abdominal pressure using oral gastric tube. This study aims to assess effects of gastric tube insertion during anesthesia induction on nausea and vomiting of adenotonsillectomized patients. This study was a clinical trial on 72 adenotonsillectomised children aged 6 to 12 years old in Shahid Montazeri hospital of Najaf-Abad. Patients were randomly divided to two groups of case group (36 Children with oral gastric tube) and controls group (36 children without oral gastric tube). Anesthesia method for both groups was similar. Frequency of nausea and vomiting were measured during the 24 hours following adenotonsillectomy. Data was analyzed using SPSS 15 and Mannwhithney U, Chi square, Spearman, Friedman and wilcoxon tests. Two groups were not significantly different regarding their demographic characteristics such as age, sex and weight (p>0.05). Frequencies of nausea and vomiting were significantly lower in the intervention group comparing to the control group in the first 2 hours in recovery room as well as in the first 2, 6, and 14 hours of patient attendance in the postsurgical ward (P ≤ 0/05). This study showed that the use of oral gastric tube during anesthesia induction can reduce nausea and vomiting after adenotonsillectomy.
