300例妇科腹腔镜手术中应用喉罩通气全身麻醉的临床观察

目的介绍和观察喉罩通气全身麻醉在妇科腔镜手术中的应用。方法选择全麻腹腔镜宫外孕输卵管切除术和卵巢肿瘤切除及腹腔镜下卵巢囊肿剥除术患者300例，均为择期手术。ASAⅠ-Ⅱ级，随机分为气管插管组（A组）150例和喉罩组（B组）150例，监测并记录两组插入喉罩或气管插管时（T1）、气腹时（T2）、苏醒拔管时（T3）的平均动脉压（MAP）、心率、呼气未二氧化碳分压（PETCO2）等变化。并对所有患者术后随访。结果①两组T1、13时的MAP比较，A组明显高于B组（P〈0．05）；②两组心率T1、仍时A组高于B组（P〈0．05），T2时差异无统计学意义；③两组PETCO2比较；B组与A组差异无统计学意义（P〉0．05）；④术后随访，A组咽喉痛、声音嘶哑、咳嗽等不良发生率反应的发生高于B组（P〈0．05）。结论喉罩通气静脉全身麻醉对血流动力学影响小，术中术后并发症少，麻醉效果可靠，操作简单，临床应用好。

Observation of laryngeal mask anesthesin in 300 cases gynaecological laparoscopic surgery

Objective To evaluate the application of laryngeal mask airway anesthesia for gynaecological laparoscopil surgery. Methods 300 ASA Ⅰ or Ⅱ patients that need elective gynaecological laparoscopic surgery were divided randomly into endotracheal intubation group(groupA n = 150 cases)and laryngeal mask airway group(group B n = 150 cases). Mean arterial presswre(MAP) , heart rate(HR) ,end-tidal partial pressure carbon dioxide (PETCO2) were recorded and evalated before intubation (T1) , when pneumoperitoneum (T2) and after extubation (T3). The patients of porstopertion following-up were also made to all cases. Results Diffierence of MAP and HR were sitnificant between group A and B (P＜ 0. 05) at T1 and T3. While the HR was significant difference at T1 and T3. When PETCO2 was measured. the incidence rat of sore throat, hoarseness and conghing was higher in group A than group B in postoperative follwing-up. Conclusion Largngeal mask airway anesthesia has less impact on hemodynamlis as well as less postoperative complications. The anethetil procedure is feasible and the effect is reliable and satisfging.
