Abstract

Introduction: Insertion of the laryngeal mask airway after induction of anaesthesia has been described to cause less haemodynamic changes than tracheal intubation

Aim: The purpose of the study was to compare hemodynamic response during insertion of Supraglottic device (laryngeal mask airway) and cuffed endo-tracheal tube.

Materials and Methods: This was a randomized double blinded prospective study of 60 patient of age group of 17-60 years and ASA I and II who were posted for elective surgeries requiring general anaesthesia. Patients were randomly allocated into two groups (n=30) Group “A” and “B” comprising of 40 patients each.Group A – included patients who were intubated with endotracheal tube.Group B – included patients in whom supraglottic device (LMA) was inserted. Patients were continuously monitored in the intra –operative period for the following parameters Pulse rate, percentage saturation of oxygen (SPO2), Non – invasive blood pressure (NIBP), Mean arterial pressure (MAP), Rate pressure product (RPP) and ECG.

Results: The rise in mean pulse rate in ETT group higher – following laryngoscopy and intubation, than supraglottic device group. All the groups were associated with significant increase in mean arterial but in LMA group this rise was significant. Similarily the rate pressure product was significantly raised in group A as compared to group B.

Conclusion: There was significant rise in mean pulse rate, mean arterial pressure, rate pressure product in group A during insertion of the endotracheal tube after two, five minutes than the LMA group. A significantly higher numbers of attempts were required for LMA as compared to endotracheal intubation there was a significant increase in the incidence of post-operative cough and sore-throat in the endotracheal group as compared to the LMA group B.

Keywords: Mean pulse rate, LMA, rate pressure product, hemodynamic.
