Abstract:
Objective To assess the efficacy of the laryngeal mask airway i-gel (LMA i-gel) in patients umdergoing laparoscopic cholecystectomy. Methods One hundred and twenty ASA Ⅰ or Ⅱ patients of both sexes,aged 34-62 yr, weighing 45-90 kg, undergoing elective cholecystectomy using fiberoptic laparoscope, were randomized into 2 groups (n =60 each): LMA i-gel group (group I) and LMA ProSeal group (group P). After induction of anesthesia with sufentanil 0.2 μg/kg, propofol 2.5 mg/kg and vecuronium 0.1 mg/kg, LMA i-gel and LMA ProSeal were inserted in group I and P respectively. A gastric tube was inserted through the drain tube of the LMAs. The number of attempts, success rate, success rate of gastric tube placement, airway seal pressure, SpO2 ,PETCO2, peak airway pressure and complications (hypoxemia, nausea and vomiting, choking hoarseness, sore throat and regurgitation of gastric contents) were recorded. The fiberoptic laryngoscope scores were assessed after sccessful LMA placement. The anesthesia time, duration of surgery, extubation time and emergence time were also recorded. Results There was no significant difference in the anesthesia time, duration of surgery, extubation time and emergence time between the two groups ( P ＞ 0.05). The SpO2, PETCO2 and peak airway pressure were within the normal range during operation in both groups. The first attempt success rate of LMA placement and fiberoptic bronchoscopic scores were significantly higher, and the LMA placement time was significantly shorter in group Ⅰ than in group P (P ＜ 0.05). The success rate of LMA and gastric tube placement was 100% in both groups. The incidence of sore throat was significantly lower in group I than in group P ( P ＜ 0.05). Conclusion LMA i-gel can provide adequate ventilation during operation with less complications and can be used effectively for cholecystic laparoscopic surgery.
