Abstract: Objectives: Intubating laryngeal mask airway (ILMA) offers a new approach for endotracheal intubation and is expected to produce less cardiovascular stress responses. However, the available studies provide inconsistent results. The present study was designed to compare the haemodynamic response during intubation by conventional direct laryngoscopy and intubation by ILMA. Materials and methods: After obtaining approval from the ethics and scientific committee, 100 ASA grades I?II, aged 18 - 60 years of either sex scheduled for elective surgery under general anaesthesia requiring endotracheal intubation, were randomly allocated into two groups. Patients of Group M were intubated using Macintosh laryngoscope and Group I with intubating laryngeal mask airway respectively. The general anaesthesia technique was standardized. Time to intubation, heart rate, systolic, diastolic, mean arterial blood pressure and rate pressure product were noted at various time intervals. All analysis was 2 tailed and P value of <0.05 was considered significant. Results: The two groups were comparable in terms of demographic variables. The haemodynamic parameters were higher in both the groups post endotracheal intubation when compared to the baseline values. Heart rate and rate pressure product were significantly higher in laryngoscopy group as compared to ILMA group. Systolic, diastolic and mean arterial blood pressure were higher in direct laryngoscopy group when compared to Intubating laryngeal mask airway group, but it was not statistically significant. Time to intubation was significantly higher in the Intubating laryngeal mask airway group than direct laryngoscopy group (55.0?12.1 s versus 18.8?3.8 s, P<0.001). Complications like sore throat and hoarseness were higher in direct laryngoscopy group as compared to Intubating laryngeal mask airway group. Conclusion: Use of intubating laryngeal mask airway results in significantly lower haemodynamic response as compared to direct laryngoscopy for tracheal intubation.
