Abstract:
Objective To evaluate the effect of deep and moderate neuromuscular blockade on surgical conditions during minor laparoscopic gynecologic surgery.Methods Sixty-five patients,with expected surgery time ＜ 3 h,aged 18-60 yr,with body mass index＜30 kg/m2,of American Society of Anesthesiologists physical status Ⅰ orⅡ,scheduled for elective laparoscopic gynecological surgery,were allocated into deep neuromuscular blockade group (group D,n =33) and moderate neuromuscular blockade group (group M,n=32) using a random number table.After induction of anesthesia,the patients were tracheally intubated and mechanically ventilated.Cisatracurium was continuously infused to maintain the degree of neuromuscular blockade in both groups to achieve the target degree post-tetanic count of 1 or 2 in group D and train-of-four (TOF) count of 1 or 2 in group M.Surgical conditions were assessed and scored after surgery.The recovery index,time for TOF ratio returning to 0.7 and 0.9,surgery time,mean intra-abdominal pressure,extubation time and TOF ratio at extubation were recorded.Results Compared with group M,the mean intra-abdominal pressure was significantly decreased,and the extubation time and time for TOF ratio returning to 0.7 and 0.9 were prolonged in group D (P＜0.05).There was no significant difference in the other parameters between the two groups (P＞0.05).Conclusion Moderate neuromuscular blockade can provide better surgical conditions for minor laparoscopic gynecological surgery with shorter recovery time.
