Eligibility

Inclusion criteria

Inclusion criteria: ASA Grade 1 and 2. Age 21-50 years. Undergoing surgery under general anaesthesia in supine position.

Exclusion criteria

Exclusion criteria: Refusal to participate. Patients with anticipated difficult airway. Patients having upper respiratory tract infection. Patients at risk of GE regurgitation. Patients with limited mouth opening. History of upper GI surgery. Mass in pharyngeal/laryngeal cavity. Unsuccessful I-gel insertion even after three attempts.

Design outcomes

Primary

MeasureTime frame
To compare the incidence of malposition of I-gel (by assessing the fiberoptic score) between blind and macintosh laryngoscope guided insertion, in anaesthetized adults. To compare mean oropharyngeal leak pressure between blind and macintosh laryngoscope guided insertion groups.Timepoint: Time for placement of SGA device in seconds at baseline.—

Secondary

MeasureTime frame
To compare insertion characteristics (ease of insertion, number of attempts) in both the groups. To determine any difference in hemodynamic changes (BP, HR, SPO2). To determine incidence of complications (laryngospasm, tissue trauma, nerve injuries) if any, in both the groups.Timepoint: Time required for successful insertion of SGA in seconds at baseline.—
