i-gel喉罩用于妇科腹腔镜手术患者气道管理的效果

Efficacy of laryngeal mask airway i-gel in patients undergoing laparoscopic gynecological surgery

目的 评价i-gel喉罩用于妇科腹腔镜手术患者气道管理的效果.方法 择期全麻下拟行妇科腹腔镜手术患者60例,ASA分级Ⅰ或Ⅱ级,年龄21～64岁,体重45～90 kg,Mallampatti分级Ⅰ～Ⅲ级,采用随机数字表法,将其随机分为2组（n=30）：i-gel喉罩组（I组）和Supreme喉罩组（S组）.根据体重选择喉罩型号,麻醉诱导后置入喉罩,经引流管放置胃管,行机械通气.记录喉罩置入时间、置入次数、胃管置入次数、喉罩密封压、纤维支气管镜检查分级、术中血液动力学指标、通气指标、麻醉时间和苏醒时间,记录拔除喉罩后咽喉痛、吞咽痛和声音嘶哑的发生情况.结果 两组麻醉时间、苏醒时间、喉罩置入时间、纤维支气管镜检查分级、术中血液动力学指标和通气指标差异无统计学意义（P〉0.05）.两组喉罩和胃管置入成功率均为100%.与S组比较,I组喉罩密封压升高,咽喉痛和吞咽痛发生率降低（P〈0.05或0.01）.结论 i-gel喉罩气道密封性可靠,并发症少,可安全有效地应用于妇科腹腔镜手术患者的气道管理.

Objective To assess the efficacy of laryngeal mask airway （LMA） i-gel used in patients undergoing laparoscopic gynecological surgery. Methods Sixty ASA Ⅰ or Ⅱ patients, aged 21-64 yr, weighing 4590 kg, undergoing elective laparoscopic gynecological surgery, were randomized into 2 groups （ n = 30 each）：LMA i-gel group （group Ⅰ） and LMA Supreme group （group S） . Mallampatti test was performed before operation in both groups. Anesthesia was induced with target-controlled infusion of propofol （target plasma concentration 2.5-4.0 μg/ml） and remifentanil （target plasma concentration 3-6 ng/ml） . After the patients lost consciousness, rocuronium 0.6 mg/kg was given to facilitate the LMA insertion. LMA i-gel and LMA Supreme were inserted in I and S groups respectively. A gastric tube was inserted through the drain tube of the LMA. In group S the air was injected into the cuff to make intracuff pressure reach 60 cm H2O after successful LMA insertion. The LMA placement time, the number of attempts of LMA insertion, the number of attempts of gastric tube placement, the airway sealing pressure, the parameters of hemodynamics and ventilation, and complications （sore throat, odynopliagia,hoarseness） were recorded. The fiberoptic laryngoscopy scores were assessed after successful LMA placement. The anesthesia time and recovery time were also recorded. Results There was no significant difference in the anesthesia time, recovery time, LMA placement time, fiberoptic bronchoscopy scores and the parameters of hemodynamics and ventilation between the two group. The success rates of LMA and gastric tube placement were 100% in both groups. The airway sealing pressure was significantly higher, while the incidence of sore throat and odynopliagia was significantly lower in group I than in group S. Conclusion LMA i-gel provides adequate ventilation during operation with fewer complications and can be used effectively for gynecological laparoscopic surgery.
