Supreme喉罩与i-gel喉罩用于俯卧位腰椎手术患者气道管理效果的比较

目的比较Supreme喉罩和i-gel喉罩用于俯卧位腰椎手术患者气道管理的效果。方法择期行俯卧位腰椎手术患者264例,采用随机数字表法将患者分为两组,每组132例。麻醉诱导后S组和I组分别置入Supreme喉罩和i-gel喉罩。记录喉罩置入次数、置入时间;记录仰卧位和俯卧位时的通气质量、气道峰压、气道密封压,并采用纤支镜观察喉罩位置,行喉罩对位分级;记录喉罩血染的发生情况;记录喉罩相关并发症的发生情况。结果 I组有1例患者于仰卧位时3次置入喉罩均失败,被排除。两组患者置入喉罩型号、置入时间、仰卧位和俯卧位气道峰压和纤支镜评级差异无统计学意义。与S组比较,I组喉罩尝试置入次数明显增多,俯卧位通气质量明显升高,俯卧位和仰卧位气道密封压明显升高(P0.01或P0.05)。两组患者喉罩相关并发症发生情况差异无统计学意义。结论俯卧位腰椎手术患者气道管理中,相比Supreme喉罩,i-gel喉罩置入难度较大,但具有更高的气道密封压。

Comparison of the efficacy of laryngeal mask of Supreme and laryngeal mask of i-gel for the airway man-agement in patients undergoing elective lumbar vertebral surgery in prone position

Objective To compare the efficacy of laryngeal mask of Supreme and i-gel for the airway management in patients undergoing elective lumbar vertebral surgery in prone position. Methods A total of 264 patients,ASA physical status Ⅰ or Ⅱ,scheduled for elective lumbar verte-bral surgery in prone position under general anesthesia were divided into two groups (n =132)using a random number table:laryngeal mask of Supreme group (group S)and laryngeal mask of i-gel group (group I).The laryngeal mask of Supreme or i-gel were respectively placed in group S and group I im-mediately after anesthesia induction according to manufacturers’specification.Volume-controlled ven-tilation was used to observe the ventilation quality.The number of laryngeal mask insertion,laryngeal mask insertion time and the ventilation quality in supine and prone position were recorded,as well as the airway seal pressure.The position of laryngeal mask was evaluated by fibero ptic examination in both supine and prone positions.The blood on the laryngeal mask was noted.Finally,the occurrence of laryngeal mask related complications was observed.Results One patient in group I was excluded due to the failure of laryngeal mask insertion after three attempts.No significant difference in type of laryngeal mask,insertion time,adjusted cases,peak airway pressure,and fiber optic examination in both supine and prone positions between two groups.Compared with group S,group I required signif-icantly more attempts of insertion (P < 0.01 ).Nevertherless,ventilation quality in prone position was improved and airway seal pressure in supine and prone position increased (P <0.01 or P <0.05) in group I.No significant difference was found in the occurrence of laryngeal mask related complica-tions.Conclusion In the airway management of patient undergoing elective lumbar vertebral surgery in prone position,laryngeal mask of i-gel is more difficult to be inserted but can maintain higher air-way seal pressure compared with laryngeal mask of Supreme.
