Title: The Research of the Application of Laryngeal Mask Airway under Direct Vision in Minimally Invasive Cholecystectomy
Abstract: Objective To observe the influence of laryngeal mask and tracheal intubation on mean arterial pressure(MAP) and heart rate(HR)under direct vision in minimally invasive gallbladder removal surgery.Methods The patients were randomly divided into two groups:laryngeal mask and intubation group,20 cases each.For the induction of anesthesia,midazolam 0.03 mg/kg,fentanyl 3-4 μg/kg,propofol 2-2.5 mg/kg,and vecuronium 0.1 mg/kg were administered.After administration into the laryngeal mask or endotracheal tube,patients′ MAP and HR changes were observed before and after laryngeal mask or endotracheal tubeat different time points.Medication during the surgery,consciousness regaining time,throat complications after the surgery discovered during the follow-up were observed.Results Compared with entering the operating room(T0),after induction MAP and HR were obviously lower(P0.05)at different time points in both groups with statistically significant differenceDifference between the laryngeal mask group and intubation group was statistically significant(P0.05).At two different time points intubation group MAP and HR fluctuations were obviously higher than the laryngeal mask group(P0.05).Conclusion In minimally invasive direct vision gallbladder surgery,the use of laryngeal mask airway anesthesia is featured with shorter recovery timeand stable MAP and HR,which is worthy to be popularized.
