Comparative evaluation of three different techniques (standard, reverse and rotation) of I-Gel insertion in patients undergoing surgery under General Anaesthesia

This randomised, controlled trial aims to compare the efficacy of the three techniques of iGel insertion in adult patients undergoing elective surgeries under general anaesthesia. A total of 264 ASA I–II patients will be randomly divided into three groups: standard technique (Group S), reverse technique involving a 180° rotation (Group R), and rotational technique using a 90° rotation (Group T). After standard anaesthetic induction and neuromuscular relaxation, the i-gel will be inserted using the assigned technique. Key outcome measures included first-attempt success rate, insertion time, oropharyngeal leak pressure, ease of gastric tube placement, fibreoptic grading, and the incidence of complications such as sore throat, blood staining, and dysphagia at 1 and 24 hours.

By providing a comprehensive head-to-head comparison of standard, reverse, and rotational i-gel insertion methods, this research intends to generate clinically relevant evidence that can enhance anaesthetic practice. The findings are expected to assist anaesthesiologists in selecting the most effective technique for i-gel placement, thereby improving patient safety and procedural efficiency in airway management.
