A study to compare the changes in the pressure in the eye, blood pressure and heart rate during insertion of tube in the trachea by direct laryngoscopy [ a tube meant for direct visualization of inside of the larynx] versus intubation through ILMA [ a less invasive device].

Design outcomes

Primary

MeasureTime frame
Rise in IOP is lesser in the ILMA group. Hence intubation via ILMA should preferred in patients of glaucoma or open eye injury patients.Timepoint: Baseline (Premedication room). After endotracheal intubation (Group DL â?? by direct laryngoscopy, Group IL- through ILMA, before removal of the device). 2 min. and 5 min. after intubation.—

Secondary

MeasureTime frame
Use of ILMA for intubation is also associated with lesser rise in blood pressure and heart rate compared to that in intubation via laryngoscopy. Hence, it should be preferred in patients at risk of myocardial ischemia or stroke.Timepoint: Baseline Before induction Before device or endotracheal tube insertion. Just after endotracheal intubation. 2 min, 5 min., 7min, 10 min, 15 min and 30 min after endotracheal tube insertion.—
