The Evaluation of Proseal Laryngeal Mask Airway as an Alternative to Endotracheal Intubation in Patients Undergoing Laparoscopic Cholecystectomy
Journal Title: Indian Journal of Anesthesia and Analgesia - Year 2019, Vol 6, Issue 1
Abstract
Context: Proseal laryngeal mask airway is a supraglottic airway device with an additional drainage tube and a dorsal cuff which provides better seal and prevents aspiration. Aims: 1) tocompare the efficacy of PLMA with standard intubation in patients undergoing laparoscopic cholecystectomy. Methods and Material: After approval from institutional ethical committee a prospective randomized controlled study was conducted in sixty ASA class 1 and 2 patients. After induction Proseal LMA was introduced in group P and endotracheal tube was introduced in group E. Details of insertion, haemodynamic parameters, ventilatory performance were recorded. During surgery, oxygenation and ventilation variables were adjusted to maintain SpO2 > 95% and EtCO2< 45 mmHg. Statistical analysis used: Data was analysed using computer statistical software system openepi (open source epidemiological statistics for public health). The two tailed students t test was for unequal variance was used for intergroup comparisons except where specified. Probability values p < 0.05 were considered significant and p < 0.001 were considered highly significant. Results: There was no failed insertion of devices. The mean time of insertion of Proseal (80+43.56 seconds) was greater than conventional intubation (23+17.71 seconds). The difference was statistically highly significant (p<0.01). There were no statistically significant differences in oxygen saturation (SpO2) or endtidal carbon dioxide (EtCO2) between the two groups before or during peritoneal insufflation. There was no case of inadequate ventilation, regurgitation, or aspiration recorded. Conclusions: Proseal provides a safe alternative to endotracheal intubation for airway management in patients undergoing laparoscopic cholecystectomy.

Comparative Study of the Effect of Dexmedetomidine v/s Fentanyl on Intraoperative Hemodynamic Response in Robot Assisted Lower Abdominal Onco-Surgeries in Steep Trendlenburg Position
Introduction: Carbon dioxide insufflation for pneumoperitoneum causes increase plasma levels of catecholamines and vasopressin which leads to hemodynamic disturbances. These effects are exaggerated by the Trendelenburg p...
Effect of Dexmedetomidine on Haemodynamic Response to Pneumoperitoneum in Patients Undergoing Laparoscopic Cholecystectomy
Background: As laparoscopic cholecystectomy is a routinely performed surgery, it is desirable to have a stable intraoperative haemodynamic status. This study is designed to evaluate the efficacy of single intravenous bol...
