This study was designed to investigate the cardiovascular effects related to tracheal extubation or laryngeal mask airway (LMA) removal in children.
Sixty children, ASA physical status 1, 4-10 yr of age, undergoing minor elective surgery (inguinal hernia and phimosis) were allocated randomly to have their surgery performed with endotracheal intubation (Group ET, n = 30) or LMA (Group LMA, n = 30) and were studied for cardiovascular responses related to extubation or LMA removal. Changes in heart rate (HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured before and 1, 2, 3, 5, and 10 min after tracheal extubation or LMA removal when the patients were awake.
The maximal changes in HR, SBP and DBP were less in Group LMA than in Group ET during the observation period (HR; 12 vs 26, SBP; 14 vs 28, DBP; 9 vs 13, median, P < 0.05).
Laryngeal mask airway removal elicited less haemodynamic change than tracheal extubation in paediatric patients.
本研究旨在调查儿童气管拔管或喉罩气道（LMA）移除相关的心血管效应。
60例年龄4 - 10岁、ASA身体状况为1级、接受小型择期手术（腹股沟疝和包茎）的儿童被随机分配，分别接受气管插管（ET组，n = 30）或喉罩气道（LMA组，n = 30）进行手术，并研究与拔管或LMA移除相关的心血管反应。在患者清醒状态下，于气管拔管或LMA移除前以及移除后1、2、3、5和10分钟测量心率（HR）、收缩压（SBP）和舒张压（DBP）的变化。
在观察期内，LMA组HR、SBP和DBP的最大变化小于ET组（HR：中位数12对26，SBP：14对28，DBP：9对13，P < 0.05）。
在儿科患者中，移除喉罩气道引起的血流动力学变化比气管拔管少。
