喉镜辅助喉罩置入方法在下腹部手术中的临床价值

Clinical value of laryngoscope assisted laryngeal mask placement technique in hypogastric surgery

目的探讨喉镜辅助喉罩置入方法在下腹部手术中的临床价值。方法将择期行下腹部手术的60例患者随机分为喉镜辅助组(喉镜组)及经典徒手组(徒手组),每组30例,分别使用喉镜辅助法和徒手法置入喉罩。比较2组患者一次成功率、二次成功率、改插导管率、喉罩表面有血迹及术后咽痛的发生率,以及T0(诱导前)、T1(置罩前)及T2(置罩后即刻)收缩压(SBP)、舒张压(DBP)和心率(HR)的变化。结果喉镜组一次置入成功率高于徒手组,但差异无统计学意义。徒手组喉罩表面有血迹及术后咽痛发生率显著高于喉镜组。2组各时间点SBP、DBP、HR比较,差异均无统计学意义。结论在喉镜辅助下插入喉罩较徒手法置入喉罩可提高一次插入成功率,降低术后咽喉不适感。

Objective To explore the clinical value of laryngoscope assisted laryngeal mask placement technique in hypogastric surgery. Methods Sixty patients with elective hypogastric surgery were divided into laryngoscope auxiliary group （laryngoscope group） and classic unarmed group （unarmed group）, with 30 cases in each group. One-off and quadratic success rates, rate of changing into catheterization, incidences of bloodstain on laryngeal mask and postoperative pharyn- galgia as well as changes of systolic blood pressure （SBP）, diastolic blood pressure （DBP） and heart rate （HR） at To （prior to induction）, T1 （prior to mask placement） and T2 （immediately after mask placement） were compared in two groups. Results One-off success rate of placement in laryngo- scope group was higher than that in unarmed group, but the difference showed no statistical signifi- cance. The incidences of bloodstain on laryngeal mask and postoperative pharyngalgia in unarmed group were significantly higher than those in laryngoscope group. Compared with SBP, DBP and HR at each time point in two groups, and all differences showed no statistical significance. Conclu- sion Compared with laryngeal mask placement by hands, laryngoscope assisted laryngeal mask placement can improve one- off success rate of placement and decrease postoperative laryn- gopharyngeal discomforts.
