Abstract： 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.
