Summary

This prospective randomized study aims to compare two second-generation supraglottic airway devices (SGAs), the I-Gel and the laryngeal mask airway (LMA) Protector, in patients undergoing laparoscopic cholecystectomy under low-flow desflurane anesthesia. The study evaluates the devices in terms of respiratory mechanics (dynamic compliance, peak inspiratory pressure, plateau pressure, and airway resistance), non-invasive perfusion parameters (oxygen reserve index, perfusion index, and pleth variability index), hemodynamic stability, ease of insertion, oropharyngeal leak pressure, and postoperative complication rates.

Conditions

  • Laparoscopic Cholecystectomy
  • Anesthesia, General

Interventions

DEVICE

I-Gel supraglottic airway

Placement of an appropriate size of i-gel supraglottic airway device for airway management during general anesthesia. Anesthesia maintenance is provided with desflurane in a fresh gas flow of 1 L/min (low-flow anesthesia).

DEVICE

LMA Protector supraglottic airway

Placement of an appropriate size of LMA Protector supraglottic airway device for airway management during general anesthesia. Anesthesia maintenance is provided with desflurane in a fresh gas flow of 1 L/min (low-flow anesthesia).
