Prompt insertion and placement of supraglottic airway (SGA) devices in the correct position are required to secure the airway. This meta-analysis was performed to validate the usefulness of the 90° rotation technique as compared with the standard digit-based technique for the insertion of SGA devices in anesthetized patients in terms of insertion success rate, insertion time, and postoperative complications.
A literature search of PubMed, EMBASE, CENTRAL, CINAHL, Scopus, and Web of Science was conducted. Randomized controlled trials, without limitations on publication period, language, journal, or region, until July 2021, that compared the 90° rotation and the standard digit-based techniques for insertion of SGA devices in anesthetized patients were included.
The first-attempt (risk ratio [RR]: 1.16, 95% CI [1.09, 1.25], P < 0.001) and overall success rates (RR: 1.06, 95% CI [1.03, 1.09], P < 0.001) were significantly higher in the 90° rotation group. The insertion time was shorter in the 90° rotation group (mean difference: -4.42 s, 95% CI [-6.70, -2.15 s], P < 0.001). The incidences of postoperative sore throat (RR: 0.63, 95% CI [0.49, 0.83], P < 0.001) and blood staining (RR: 0.28, 95% CI [0.20, 0.39], P < 0.001) were lower in the 90° rotation group.
The use of the 90° rotation technique increases the success rate of SGA device insertion and decreases postoperative complications as compared with that of the standard digit-based technique in anesthetized patients.
在为患者建立气道时,需要将声门上气道(SGA)装置快速准确地插入并放置到正确位置。本荟萃分析旨在验证与标准数字技术相比,90°旋转技术在麻醉患者中插入 SGA 装置时的插入成功率、插入时间和术后并发症方面的有效性。
对 PubMed、EMBASE、CENTRAL、CINAHL、Scopus 和 Web of Science 进行文献检索。纳入无发表时间、语言、期刊或地区限制的随机对照试验,比较了麻醉患者中 90°旋转技术与标准数字技术插入 SGA 装置的情况。
90°旋转组的首次尝试(风险比 [RR]:1.16,95%可信区间 [1.09,1.25],P < 0.001)和总体成功率(RR:1.06,95%可信区间 [1.03,1.09],P < 0.001)显著更高。90°旋转组的插入时间更短(平均差:-4.42 s,95%可信区间 [-6.70,-2.15 s],P < 0.001)。90°旋转组术后咽喉痛(RR:0.63,95%可信区间 [0.49,0.83],P < 0.001)和血污(RR:0.28,95%可信区间 [0.20,0.39],P < 0.001)的发生率较低。
与标准数字技术相比,在麻醉患者中使用 90°旋转技术可提高 SGA 装置插入成功率,降低术后并发症发生率。
