Background: Postoperative vomiting (POV) is one of the most serious complications in pediatric patients undergoing strabismus surgery. This study was conducted to test the hypothesis that gastric decompression (GD) could prevent POV caused by gastric distension after mask ventilation.
Methods: A total of 60 pediatric patients (ASA PS I?II, aged one to 10 years) were randomly allocated to two groups; Group D (n = 30) and Group C (n = 30). Induction of anesthesia was performed with careful face mask ventilation with 100% O2 (3 L/min) and sevoflurane 3 vol% to limit airway pressure below 20 cmH2O. Endotracheal intubation was done after confirming adequate neuromuscular blockade. Then, the patients in Group D received GD, while patients in Group C did not. After the surgery, POV was assessed during the emergence from anesthesia in the operating room and postanesthetic care unit (30 min and 60 min).
Results: During the emergence, POV was significantly decreased in Group D compared to Group C (Group D 3.3% vs. Group C 30.0%, P = 0.006). The odds ratio analysis showed a lower incidence of POV in Group D (odds ratio = 0.080; 95% confidence limit: 0.009?0.685) during the emergence period. There was no significant difference in the incidence of POV in the postanesthetic care unit (Group D 6.7% vs. Group C 4.3% at 30 min, P = 1.000; 0% in both groups at 60 min).
Conclusions: GD reduced the incidence of POV in pediatric patients undergoing strabismus surgery during emergence.
