Abstract

Background and Aims: ProSeal Laryngeal Mask Airway (PLMA) has been proven to cause minimal hemodynamic fluctuations and postoperative complications when compared to cuffed Endotracheal Tubes (ETT) in laparoscopic surgeries. Hence, present study was done to compare ABG analysis and hemodynamic parameters in patients undergoing laparoscopic cholecystectomy. Materials and Methods: Present study included fifty American Society of Anesthesiologist Class I patients weighing 30–70 kg within age group of 20–60 years posted for elective laparoscopy cholecystectomy after the ethical committee clearance and were randomly allocated to either PLMA (Group I) or ETT (Group II) group with 25 in each group. Hemodynamicr esponses, ABG analysis and postoperative complications were noted and compared. Results: There was no demographic difference. When we analyzed heart rate, systolic and diastolic blood pressure, mean arterial
pressure values, they were found to be comparable throughout except for those after insertion (p < 0.05). The ABG analysis and EtCO2 before pneumoperitoneum and one hour after pneumoperitoneum showed no
significant difference (p > 0.05) with either of the device. No case of regurgitation or aspiration found in either group. Postoperative complications were mainly seen with ETT Group. Conclusion: Metabolic effects of either PLMA and ETT during laparoscopy cholecystectomy were similar but PLMA affects the hemodynamic parameters to a lesser degree making it a better choice.
