A Study of The Intraoccular Pressure and Cardiovascular Changes During Insertion of Laryngeal Mask Airway

Dr. Gauri Panjabi, Dr. Shivang Joshi

Abstract :

The study was carried out in 60 ASA I/II patients undergoing various elective surgery under General anesthesia. All patients were premedicated with I.V. Midazolam 1mg, Inj. Fentanyl 2�g/kg and Glycopyrolate 2mg, 10 minutes before surgery. 2 to 3 drops of tropical lignocaine 4 % was instilled into both the eyes. IOP was measured by an ophthalmologist with a Schiotz tonometer. Following Pre oxygenation for 3 minutes, induction of anesthesia achieved with propofol 2.5-3mg/ kg. LMA was luicated on the posterior surface and inserted after eyelash reflex lost. Anesthesia was maintained with oxygen, nitrous oxide and Halothane. The IOP and cardiovascular changes were recorded preoperatively as well as at regular intervals after LMA insertion. Mean IOP changes showed decreasing trend from baseline and remained low throughout the surgery. Mean pulse rate was increased at the time of insertion of LMA (5-10/min.) but reached to baseline values within 10 min. MAP and ECG showed no significant changes during surgery. The incidence of postoperative complications like cough, sore throat and vomiting were very less and mild in nature.
