COMPARISON OF INTRAOCULAR PRESSURE AND HAEMODYNAMIC RESPONSES TO INSERTION OF THE I - GEL AND ENDOTRACHEAL TUBE IN ELECTIVE OPHTHALMOLOGICAL SURGERIES

ABSTRACT Objective: To compare I-Gel versus endotracheal tube effects on hemodynamic stability and intraocular pressure in patients undergoing elective ophthalmological surgeries. Study Design: Quasi-experimental study. Place and Duration of Study: Armed Forces Institute of Ophthalmology, Rawalpindi Pakistan, from Nov 2019 to Oct 2020. Methodology: A total of 108 patients undergoing elective ophthalmological surgeries under general anesthesia from both genders, age range between 18-45 years, American Society of Anesthesiologists status I or II were included. General anesthesia given following standard procedures and monitoring. Heart rate, Systolic and Diastolic blood pressure monitored and intraocular pressure measured in each eye with Reichert ton open at baseline, upon insertion of airway device and 5 minutes after insertion. Results: Total 108 patients enrolled in the study with a mean age of 37.74 ± 6.0 years and age-range of 18-45. Heart rate at Insertion in I-Gel group was 78.14 ± 3.41 beats per minute whereas in intubated group was 97.20 ± 2.84 beats per minute, mean systolic blood pressure at insertion in group A and B was 115.28 ± 5.3 and 130.44 ± 2.81mm of Hg respectively. Intraocular pressure at insertion right eye in group A and B was 12.04 ± 0.48 and17.98 ± 0.42 mm of Hg respectively. Intraocular pressure at insertion left eye in group A was 12.12 ± 0.45 whereas in group B was 17.95 ± 0.38mm of Hg (p-value=0.001). Conclusion: I-Gel provides better hemodynamic profile and intraocular pressure stability when compared with endotracheal tube.
