喉罩在小儿短小全麻手术中的应用

摘要

Objective:To Observe the safety of LAM applied in general anesthesia for pediatric micro-soma.Methods:Select 40 cases of selective pediatric operation and randomly divide them into LAM group(L group)and tracheal cannula group(T group),20 cases for each group,observe thoracic movement,waveform of PetCO2,and determine the position of LAM according to double-lung auscultation.Record Pmean,SpO2, PetCO2 and relevant complications.Results:In L group,to compare with that before,no obvious changes were found in HR and MAP after inserting LAM ,(P >0.05),in T group,instant HR and MAP had gone up after inserting and extubating compared with that before (P <0.05).Cases of complications occurred in L group was less than that in T group,the occurrence of dysphoria during recovery and discomfort in throat were ob-viously less than that of the T group(P <0.05).Conclusion:The application of LAM in general anesthesia for pediatric microsoma is easy to operate ,and there would be less stressful reaction,and the ventilation is satis-fying,and there would be less throat Complications,it is safe and reliable.%目的：：观察 LMA 喉罩在小儿短小全麻手术中的安全性。方法：择期小儿手术40例,随机分为喉罩组(L 组)和气管插管组(T 组),每组20例。通过观察胸廓运动、PetCO2波形、双肺听诊来确定 LMA 喉罩的到位情况。记录患儿 HR、MAP、气道平均压(Pmean)、Spo2、PetCo2及相关并发症。结果：L 组 HR、MAP 在置入喉罩前后和拔除喉罩前后无明显变化(P >0.05)；T 组 HR、MAP 在插管后即刻与插管前、拔管后即刻与拔管前比较明显升高(P <0.05),L 组并发症例数少于 T 组,苏醒期躁动、咽喉不适发生率明显少于 T 组(P <0.05)。结论：LMA 喉罩用于小儿短小全麻手术,操作简便,应激反应小,通气满意,且咽喉并发症少,安全可靠。
