A Randomised Controlled Study of Comparison of Intraocular Pressure and Haemodynamic Responses to Insertion of the I-Gel, Classical Laryngeal Mask Airway and Endotracheal Tube

Abstract

BACKGROUNDThe I-gel is a supraglottic airway device with soft gel like non-inflatable cuff. Compared to Classical LMA, I-GEL does not require cuff inflation. I-gel works in harmony with the patient's anatomy, so that compression and displacement trauma are significantly reduced. LMA and I-gel are supraglottic airways compared to Endotracheal Tube (ETT), which is inserted inside the trachea. This study was done to determine the: 1. Intraocular pressure and 2. Haemodynamic response and compare it between I-gel insertion, classical LMA insertion and laryngoscopy with endotracheal intubation.

Comparison of Intraocular Pressure and Haemodynamic Responses to Insertion of the I - Gel and Endotracheal Tube in Elective Ophthalmological Surgeries

“…These increases were significantly higher than which followed insertion of the I-Gel device. Results are relevant to our evaluation as enumerated (table-II) 20 .…”

Comparison of Thiopentone (1.25%) and Propofol (1%) for Insertion of Laryngeal Mask Airway in Paediatric Patients

“…Response to insertion of LMA was graded on 18-point scale suggested by P. Sivalingum et al (1999), 13 jaw relaxation, ease of insertion, gagging, coughing, laryngospasm and limb movements were noted & graded as excellent, good, satisfactory& poor for insertion of LMA Mean total score was good with Propofol and it was statistically significant (<0.05). 14 LMA was inserted in single attempt in 96% cases with Propofol whereas with Thiopentone 76% patients achieved single attempt insertion. 8% cases required abandonment of LMA in Thiopentone group, no such cases were noted with propofol.…”
