Comparison of haemodynamic changes following tracheal intubation by using laryngoscope with intubating laryngeal mask airway

ABSTRACT

To compare haemodynamic changes following tracheal intubation using direct laryngoscopic technique with intubating laryngeal mask airway technique. Randomized control trail [RCT]. Military Hospital Rawalpindi from Jan 2008 to Dec 2008. After approval by the hospital ethics committee, 100 patients admitted for elective surgery from OPDs were randomly distributed equally in groups I and 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. 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]. Intubation with ILMA produces less haemodynamic response as compared to direct laryngoscopy
