Comparison of Frequency of Complications of i-Gel and Laryngeal Mask Airway Supreme™ in Laparoscopic Cholecystectomy

Abstract

Aim: To compare the frequency of complications of i-gel versus laryngeal mask airway supreme™ (LMA Supreme) in laparoscopic cholecystectomy. Study Design: Randomized Controlled Trial Place and Duration of Study: Department of Anesthesia, Jinnah Postgraduate Medical Institute Karachi from 16th September 2019 to 15th March 2020. Methodology: One hundred and fifty four patients having gallstones ≤5 in numbers (size <2cm) on ultrasound for >6 months requiring cholecystectomy and planned for elective list under general anesthesia of age ranges from 25-55 years of both gender were included. Patients with known or predicted difficult airway, oropharyngeal pathology, cervical spine fracture, GERD and hiatus hernia were excluded. In group A, airway was secured with i-gel while in group B, airway was secured with laryngeal mask airway supreme™. In all patients, anesthesia was given by one consultant anesthetist (at least 3 years 0f post-fellowship experience). All patients were followed by the researcher in the first 24 hours for presence or absence of dysphagia and sore throat. Results: The mean age was 34.78±6.30 years in group A and 34.38±6.37 years in group B. Majority of the patients 119 (77.27%) were between 25 to 40 years of age. There were 54 (35.06%) males and 100 (64.94%) were females with male to female ratio of ratio of 1:2.9. The complications of i-gel vs laryngeal mask airway supreme™ were found to be as follows; dysphagia on 0.0% vs 6.49% (p-value = 0.023) and sore throat in 3.90% vs 20.78% (p=0.001). Conclusion: The frequency of dysphagia and sore throat is less after i-gel use in laparoscopic cholecystectomy as compared to laryngeal mask airway supreme™.
