Application of the modified rapid sequence induction combined with laryngeal mask airway i-gel in laparoscopic gallbladder surgery

Objective: To observe the effects of the modified rapid sequence induction combined with laryngeal mask airway(LMA) i-gel on the hemodynamics during induction period and surgical site grade in laparoscopic gallbladder surgery.Methods: Eighty laparoscopic cholecystectomy patients scheduled by laparoscopic gallbladder surgery were randomly divided into the modified rapid sequence induction group(group M)and conventional rapid induction(group C)(40 cases each group).The group M were induced with gradation dose combined without artificial positive pressure ventilation,the group C were induced with conventionally intravenous way.The arterial pressure and biochemical indexes in two groups were detected by radial artery puncture under local anesthesia before anesthesia induction.The speeds of the injection and transfusion were 1 ml/s and 10 ml·kg^-1·h^-1 in two groups,respectively.The heart rate,mean arterial pressure,pulse oxygen saturation,arterial blood oxygen partial pressure and arterial blood CO₂ partial pressure of two groups were recorded at the time of pre-induction,post-induction 2 min,post-insertion LMA 1min and 5min,and the operation field was rated.Results: Compared with group C during induction,the hemodynamics of group M was stable.The fineness rate of the operation field grade in group M was higher than that in group C(P<0.05).Conclusions: Compared with the conventional rapid induction,the modified rapid sequence induction is stable hemodynamics and no lack of oxygen and carbon dioxide accumulation,which is suitable for induction in laparoscopic gallbladder surgery,can avoid the reflux,aspiration and gastrointestinal flatulence,and has a good prospect of clinical application.
