Abstract

Introduction: Upper gastrointestinal endoscopy requires effective airway management to ensure patient safety, procedural ease, and hemodynamic stability. The LMA Gastro™, is a second-generation device with a dual channel for simultaneous ventilation and gastric access. This study aimed to evaluate its clinical performance, hemodynamic response, recovery profile, and complication rates in participants undergoing upper GI endoscopy under general anesthesia. Materials and Methods: A prospective observational study was conducted at a tertiary care hospital after obtaining ethical clearance (Ref. No: GEMREC01012022). One hundred adult participants (ASA I-III) scheduled for elective upper GI endoscopy under general anesthesia using LMA Gastro™ were included. Standard monitoring was applied, and hemodynamic parameters (pulse rate, systolic and diastolic pressures, SpO?) were recorded at predefined intervals. Procedure duration, recovery time, postoperative complications, and endoscopist satisfaction were noted. Data were analyzed using SPSS v27, applying Friedman, Chi-square, and non-parametric tests, with p < 0.05 considered significant. Results: The mean age of participants was 56.15 ± 16.16 years. Successful LMA insertion was achieved on the first attempt in 90% of participants. Significant but clinically acceptable reductions were noted in pulse rate, SBP, and DBP intraoperatively (p < 0.001), while SpO? remained stable (>99%). The mean procedure duration was 32.25 ± 17.66 min, and recovery time averaged 9.78 ± 2.41 min. Complications were minimal (12.9%), with sore throat being most common. Endoscopist satisfaction was high (median 4, IQR 4-5). Conclusion: LMA Gastro™ provides a secure airway with stable hemodynamics, rapid recovery, and minimal complications, making it a safe and efficient option for upper GI endoscopy.
