Randomized comparative study between ProSeal laryngeal mask airway (PLMA) and Endotracheal tube (ETT) for airway management in laparoscopic cholecystectomy under general anesthesia

Abstract

Background: The anesthetic technique employed in laparoscopic procedures offers many challenges and is limited most frequently to general anesthesia with controlled ventilation. Till date cuffed endotracheal tube is being considered ideal for such procedures but lesser invasive devices like PLMA are being successfully used nowadays. Aims: The present study was conducted to compare PLMA and ETT for airway management in laparoscopy cholecystectomy under general anesthesia. Material and Methods: The clinical trial included 50 patients scheduled for elective laparoscopy cholecystectomy. The ethical committee clearance and written consent were taken and patients were randomly allocated to either PLMA or ETT group. Insertion characteristics of PLMA and ETT and of nasogastric tube (NGT) via PLMA and ETT were noted. Hemodynamic responses, intra-operative as well as postoperative complications were also compared in both the groups. Results: There was no demographic difference. The difference in insertion attempts as well as the time taken for insertion was significantly less in PLMA group than ETT group. We observed that HR,SBP, DBP, MAP values were comparable at all intervals except for those after insertion. There was no case of regurgitation or aspiration noted in any of the patients in each group. Post-operative complications were mainly seen in ETT group with no statistical difference. Conclusion: PLMA and ETT show similar efficacy during laparoscopy cholecystectomy under general anesthesia and so PLMA is an efficient and safe tool for airway management.
