Abstract
Background: Significant increase in heart rate and arterial blood pressure due to laryngoscopy and tracheal intubation
have been associated with acute left ventricular failure, ruptured cerebral aneurysm, cardiac dysarrythmia and ischemia
electrocardiographic changes. Objective: To assess changes in the haemodynamic parameters after laryngeal mask
airway insertion. Methods: In this study, 80 patients of ASA grade I and II were randomly divided into two Groups A and
B. All the patients of both the Groups were posted for elective surgery. Informed and written consent was obtained from
the patients. Group A patients received Inj Lignocaine (Xylocard) 1.5 mg/kg intravenously 90 seconds before LMA
insertion. Group B patients received inj. placebo (0.9% normal saline). Heart rate, blood pressure and SpO2 were
recorded at various periods. Results: There were significant changes in all the haemodynamic variables except DABP
after LMA insertion. Intergroup comparison at ten minutes after LMA insertion shows significant changes in the heart
rate and MAP only and the changes in the SABP and DABP were not significant. Conclusion: LMA insertion improves
the conditions for LMA insertion. Although it does not abolish the pain of injection of Propofol completely, it does
decrease the intensity of the pain in majority of patients.
