摘要
目的观察乳腺癌根治手术中运用喉罩通气对血流动力学和通气功能的影响。方法择期行乳腺癌根治术患者50例，年龄25～65岁，ASAⅠ-Ⅱ级，随机分为气管导管组（T组）和喉罩组（L组），每组25例。记录患者人室安静5min时（TO），插管前即刻（T1）、插管后即刻（T2）、插管后3min（T3）、拔管时（T4）和拔管后3min（T5）的平均动脉压（MAP）和心率（HR）；记录间歇通气10min时（T6）、30min时（T7）和60min时（T8）的气道峰压（Ppeak）、分钟通气量（MV）、潮气量（VT）、呼气末二氧化碳分压（PETCO2）和脉搏血氧饱和度（SPO2）。结果阿组插管时、间歇通气10min、30min时MV、VT、SPO2的差异无统计学意义（P〉0.05），L组间歇通气60min时的Ppeak和PETCO2高于T组（P〈0.05），L组插管后即刻、插管后3min、拔管时和拔管后3min的MAP和HR较T组降低（P〈0.05）。结论喉罩通气麻醉操作简便，对心血管系统刺激性小，通气可靠。
Objective To investigate the effects of using laryngeal mask airway（LMA） for mechanical ventilation on hemodynamics and ventilation in patients undergoing mammary cancer radical operation. Methods Fifty ASA Ⅰ-Ⅱ patients aged 25-65 years undergoing mammary cancer radical operation were enrolled in the study. The patients were randomized to receive either LMA （n = 25） or endotracheal intubator （n=25） . HRand MAP were measured at 5 minafter entering the surgery （TO） ,before inserting LMA or intubator （T1） ,immediately after inserting （T2） ,3 rain after inserting LMA or intubator （T3） , immediately after extubating LMA or intubator （T4） and 3 rain after extubating LMA or intubator （T5）. Peak inspiratory airway pressure （Ppeak） ,minute volume （MV） , tidal volume （VT） ,SPO2,and PET CO2 were recorded at 10 rain of intermittent positive pressure ventilation （IPPV） （T6）,30 min （T7） and 60 rain （TS） Results There was no significant difference in MV,VT,SPO2 at 10 min and 30 min of IPPV between the two groups （P〉0.05） . Ppeak and PETCO2 in L group were higher than T group at 60 rain of IPPV（P〈0.05）. The changes in MAP and HR in L group at T2,T3,T4 and T5 were less than in the T group （P〈0. 05） . Conclusion LMA is superior to endotracheal intubation in reducing insertion response and removal response and is efficacious for mechanical ventilation.
