摘要
目的观察喉罩全身麻醉的通气功能。方法择期全身麻醉手术患者100例,ASAⅠ-Ⅱ级,按随机数字表法分为:喉罩组(LM组)和气管插管组(TI组),每组50例。全身麻醉诱导后,2组患者分别插入喉罩和气管插管,麻醉机控制呼吸。丙泊酚微量泵输入,监护仪监测麻醉诱导前,插管后1、5、10 min,拔管前,拔管后1、5、10 min,各时点生命体征数值,并在插管后30 min行血气分析。结果 2组患者各时点生命体征比较,气管插管后1、5、10 min TI组SBP高于LM组(P<0.01或P<0.05)。插管后1、5 min TI组DBP高于LM组(P<0.05),气管插管后1 min TI组HR高于LM组(P<0.01)。2组患者插管后30 min时点监护仪数值与血气分析比较差异无统计学意义(P>0.05)。结论喉罩机械通气效果良好,在监护仪的有效监测下全身麻醉应用是安全的。
Objective To observe the ventilation function of laryngeal mask airway（LMA） in general anesthesia.Methods One hundred ASA Ⅰ-Ⅱ patients were randomly divided into two groups：LMA group（n=50） and tracheal intubation group（n=50）.After induction of general anesthesia,laryngeal mask airway and tracheal intubation were used in LMA group and tracheal intubation group,respectively.Simultaneously,anaesthetic apparatus was used for controlling the breath.Anesthesia was maintained with intravenous infusion of propofol,and vital signs were observed with the medical monitoring equipment before induction of general anesthesia,1,5 and 10 min after intubation,before extubation,and 1,5 and 10 min after extubation.Blood gas values were measured 30 min after intubation.Results In tracheal intubation group,SBP increased 1,5 and 10 min after intubation（P〈0.01 or P〈0.05）,DBP increased 1 and 5 min after intubation,and HR increased 1 min after intubation（P〈0.01 or P〈0.05）.There were no significant differences in vital signs and blood gas values between the two groups 30 min after intubation.Conclusion LMA can effectively maintain ventilation.With a monitor,the application of LMA is safe in general anesthesia.
