Supreme喉罩与Proseal喉罩用于小儿全麻疝气手术的效果比较

Comparison of Efficacy for LMA Supreme Versus LMA Proseal in Children With General Anesthesia Undergoing Hernia Surgery

目的比较Supreme喉罩和Proseal喉罩在小儿全麻疝气手术中的临床应用效果。方法选择100例ASAⅠ~Ⅱ级择期全麻疝气手术患儿,依据数字表法随机分为S组(Supreme喉罩组,n=50)和P组(Proseal喉罩组,n=50)。依患儿体质量选择适合型号的喉罩置入。比较两组置入喉罩时间、首次置入喉罩成功率、总成功率及麻醉期间通气质量。记录并比较包括恶心、呕吐、返流、误吸、喉罩染血迹、术后哭闹躁动、声音嘶哑、胃胀气等合并症发生情况。结果 S组置入喉罩的时间明显短于P组(P<0.05)。S组置入喉罩一次成功率明显高于P组(P<0.05)。两组置入喉罩总成功率均为100%,麻醉期间通气质量差异无统计学意义(P>0.05)。S组喉罩染血迹、术后哭闹躁动及声音嘶哑的发生明显少于P组(P<0.05)。两组相关并发症发生率差异无统计学意义(P>0.05)。结论 Supreme喉罩和Proseal喉罩均可安全用于小儿全麻疝气手术,但Supreme喉罩操作更容易,成功率高,并发症少,更适合用于小儿此类手术。

Objective To compare the clinical effects of laryngeal mask airway Supreme（LMA Supreme） and LMA Proseal used in paediatric patients with general anesthesia undergoing hernia surgery. Methods Selected 100 cases ASA physical status I-II elective hernia surgery in children with general anesthesia were randomly assigned to either the Supreme group（S） or the Proseal group（P）（50 children in each group）.The insertion of appropriate device size was chosen according to children＇ body weight. The insertion time, first attempt success rate, total insertion success rate, quality of airway during anesthetic maintenance were compared and analyzed between two groups. The complications of anesthesia including nausea, vomiting, regurgitation and aspiration, blood staining of the device, crying restless, postoperative hoarseness and gastric insufflation were recorded and compared during each operation. Results Insertion time of the group S was shorter than group P（P〈0.05）. First attempt success rate was higher in group S than that in group P（P〈0.05）. Total insertion success rate was 100% in two groups. The ventilation quality during anesthesia in two groups was no statistically significant difference（P〈0.05）. The incidence rate of blood staining of the device, crying restless, postoperative hoarseness were found significantly lower than those in group P（P〈0.05）. The incidence of related complications to other similar between both groups has not statistical significant（P〈0.05）. Conclusion LMA Supreme and LMA Proseal are safe for the pediatric hernia surgery with general anesthesia, but LMA Supreme insertion was easier and first attempt success rate was higher with fewer complications, making it can be more suitable for such an operation.
