Application Of Laryngeal Mask Airway In Total Intravenous Anesthesia For Laparoscopic Cholecystectomy
Objective: To evaluate the safety and feasibility of laryngeal mask ai rway(LMA) in total intravenous anesthesia for laparoscopic cholecystectomy.
Met hods: 68 ASA I or II patients scheduling for laparoscopic cholecystectomy employ ing total intravenous LMA anesthesia were involved. Blood pressure(BP),heart r ate(HR) and pulse oxygen saturation(SpO2) were observed and recorded at patien ts entering operation room,anesthesia induced and LMA placed respectively.Whet her LMA placed successfully and air leakage were evaluated.End-tidal partial pr essure of carbon dioxide(PetCO2),airway pressure(Paw) and tidal volume(Vt) w ere recorded before and after pneumoperitoneum.Intraoperative awareness and rec overy form anesthesia were investigated.
Results: It was abortive to place lary ngeal mask airway for 4 patients.Laryngeal mask airways were placed successfull y without air leakage when controlled ventilation in 64 patients.After pneumope ritoneum Paw was increased significantly.The variation of Vt was stable.Pneumo peritoneum caused a little increase in PetCO2 which recovered normal after modif ied respiratory parameters.Hemodynamic parameters were stable during anesthesia.All patients recovered smoothly and rapidly after operation.None had intraope rative awareness and postoperation everse events.
Conclusion: Application of la ryngeal mask airway in total intravenous anesthesia for laparoscopic cholecystec tomy is safe.
