Abstract:
Objective To assess the efficacy of laryngeal mask airway (LMA) i-gel in patients required insertion of nasogastric tube before laparoscopic surgery. Methods Fifty-five ASA Ⅰ - Ⅲ patients ( Mallampati Ⅰ -Ⅲ ), aged 26-64 yr, weighing 54-73 kg, scheduled for elective laparoscopic surgery were randomly divided into 2 groups: group Ⅰ ( n= 28) and group Ⅱ ( n = 27). The size of i-gel LMA was chosen based on the patient' s weight, and i-gel LMA was inserted after induction of anesthesia with TCI of propofol and remifentanil, and iv injection of rocuronium. In group Ⅰ , the nasogastric tube was inserted through the drain tube of i-gel LMA. In group Ⅱ , the nasogastric tube was inserted through the nostril before operation. The hemodynamic parameters, SpO2 ,PETCO2 and peak airway pressure were monitored during operation. The fiberoptic laryngoscopy scores were assessed and nasogastrice tube displacement was recorled after successful LMA placement. The LMA placement time, success rate of LMA placement at the first attempt, airway sealing pressure, the occurrence of air leakage of LMA, and nasogastric tube drainage were recorded. The problems after removal of the LMA were observed and the adverse reactions within 24 h after operation were recorded. Results The hemodynamics was stable and the SpO2,peak airway pressure were within the normal range during operation in both groups. There was no significant difference in the LMA placement time, success rate of LMA placement at the first attempt, nasogastric tube drainage rate, airway sealing pressure, incidence of air leakage, fiberoptic laryngoscopy scores, problems after removal of the LMA and adverse reactions between the two groups ( P ＞ 0. 05). Conclusion i-gel LMA can provide adequate ventilation and does not interfere with the nasogastric tube drainage during laparoscopic surgery and can be used effectively for the patients required insertion of nasogastric tube before operation.
