喉罩通气全麻应用于老年人腹部手术的临床观察

Observation of Laryngeal mask airway general anesthesia used in abdominal surgery in the elderly

目的探讨气管插管和喉罩通气道用于老年全身麻醉对血液动力学的影响。方法将40例老年全麻腹部手术患者随机分为2组。喉罩组(L组):全麻诱导后置入喉罩;插管组(M组):全麻后喉镜下气管插管维持通气。分别记录诱导前(T0)、置喉罩或气管导管前(T1),喉罩置入或气插管即刻(T2),之后2min(T3),4min(T4),6min(T5),拔气导管或喉罩时(T6)等各时间的收缩压(SBP)、舒张压(DBP)、HR、EtCO2、Peak、SPO2。结果喉罩通气组循环稳定,MBP、HR的变化明显较气管插管组少。结论喉罩通气道用于老年全麻是一种安全可靠易行的方法。

Objective Making a research on tracheal intubation and laryngeal mask airway for general anesthesia on hemodynamics in elderly effects.Methods40 elderly patients with abdominal surgery general anesthesia were randomly divided into two groups.LMA group （L group）： Laryngeal mask insertion after induction of general anesthesia;Intubation group： laryngoscopy under endotracheal intubation to maintain ventilationafter general anesthesia.Data will be recorded before induction（T 0）,in the process of setting the laryngeal mask or endotracheal tube（T 1）,and laryngeal mask airway insertion or gas intubation（T 2）,and then 2m in（T 3）,4m in（T 4）,6m in（T 5）,pulling out the air duct or laryngeal mask（T 6）,and other different times′s systolic pressure（SBP）,diastolic blood pressure（DBP）,HR,EtCO_2,Peak,SPO_2.ResultsSteady circulation of laryngeal mask airway group.And the MAP,HR change was significantly less than the intubation group.Conclusion： laryngeal mask airway anesthesia in the elderly is a comparably safe and reliable method.
