COMPARISON OF HAEMODYNAMIC CHANGES FOLLOWING TRACHEAL INTUBATION BY USING LARYNGOSCOPE WITH INTUBATING LARYNGEAL MASK AIRWAY

Intubating Laryngeal Mask Airway

Abstract

Objective: To compare haemodynamic changes following tracheal intubation using direct laryngoscopic technique with intubating laryngeal mask airway technique.
Study Design: Randomized control trail (RCT).
Place and duration; Military Hospital Rawalpindi from Jan 2008 to Dec 2008.
Material and Methods: After approval by the hospital ethics committee, 100 patients admitted for elective surgery from OPDs were randomly distributed equally in groups I & II for either direct laryngoscopy or laryngeal mask airway intubation respectively, as a part of general anaesthesia. A uniform protocol of general anaesthesia was followed. Heart rate and mean blood pressure were recorded before and at 1, 3 and 5 minutes after intubation.
Results: It was observed that increase in mean arterial blood pressure and heart rate at 1 and 3 minute was significant in patients intubated with laryngoscope as compared to patients intubated with Intubating laryngeal mask airway (ILMA).
Conclusion: Intubation with ILMA produces less haemodynamic response as compared to direct laryngoscopy.
