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.
