摘要
目的比较盲探徒手与喉镜辅助置入喉罩在婴幼儿麻醉应用时一次成功率及对婴幼儿血流动力学的影响,同时比较术后拔除喉罩时并发症的发生情况。方法选择择期行下腹部手术的患儿50例,分为盲探徒手组(徒手组)和喉镜辅助组(喉镜组),各25例。记录麻醉前(T0),罩前(T1),罩后(T2),拔罩前(T3),拔罩后1min(T4)、5min(T5)的收缩压(SBP)、舒张压(DBP)、心率(HR)和末梢血氧饱和度(SPO2),并记录1次成功插罩率、2次成功插罩率和改行导管插管率,同时观察拔除喉罩时喉罩带血和术后患儿是否发生喉痉挛等并发症的发生情况。结果与T0比较,两组患儿在T1时SBP、DBP、HR均明显降低(P<0.05);在T2、T3时两组差异无统计学意义,在T4、T5时,徒手组的SBP、DBP、MBP、HR比喉镜组明显升高(P<0.05);喉镜组的一次成功率96.00%明显高于徒手组72.00%(P<0.05);术后拔除喉罩时,喉镜组无患儿发现喉罩带血,徒手组8例(P<0.05);术后喉镜组有3例患儿发生喉痉挛,徒手组有5例,两组比较差异无统计学意义。结论喉镜辅助置入喉罩在婴幼儿麻醉应用时,可提高其成功率,减少应激反应,术后咽部并发症少。
Objective To compare the success rate of the laryngeal mask airway with the aid of the classic unarmed or the laryngoscope auxiliary in infants anesthesia and its effect on the hemodynamics,and to compare the incidence of complications after the surgical remove the LMA.Methods Undergoing selective lower abdominal surgery in children with 50 cases,divided into classic unarmed group(unarmed group)and laryngoscope auxiliary group(laryngoscope group),25 cases in each group.Recorded systolic pressure(SBP)and diastolic blood pressure(DBP),heart rate(HR)and peripheral oxygen saturation(SpO_2)at before anesthesia(T_0),prior to mask placement(T_1),immediately after mask placement(T_2),before the removal of laryngeal mask(T_3),after removing the LMA 1min(T_4),5min(T_5) and record one-off and quadratic success rates,rate of changing into catheterization,incidences of bloodstain on laryngeal mask and the complications of laryngeal spasm.Results Compared with T_0,SBP,DBP and HR in two groups were decreased at T_1(P<0.05);two groups at T_2 and T_3 showed no statistical significance;SBP,DBP and MBP,HR in the unarmed group increased significantly at T_4,T_5 than the laryngoscope group(P<0.05);laryngoscope group one-off rates of 96.00%was significantly higher than that of the unarmed group of 72.00%(P<0.05);removed the laryngeal mask after the surgical,laryngoscope group no children found laryngeal mask with blood,but in the unarmed group found 8 cases(P<0.05);postoperative and removed the LMA,in laryngoscope group 3 cases occurred laryngeal spasm,in unarmed group occurred 5 cases.Conclusion Laryngoscope assisted laryngeal mask placement technique can increase the success rates,reduce stress reaction,and reduce the postoperative complications of the throat in infants anesthesia.
