Background: Airway management is the most essential manoeuvre during delivery of general anaesthesia. Traditionally, laryngoscopy and endotracheal tube (ETT) insertion has been the mainstay in providing adequate airway management and delivering anaesthesia. The laryngeal mask airway (LMA) offers a much less invasive way of maintaining the airway as it does not pass through the glottis and does not require the use of the laryngoscope. Laryngoscopy and ETT or LMA insertion are noxious stimuli which provoke a transient but marked sympathetic response manifesting as hypertension and tachycardia. Materials and Methods: A hospital based comparative study was conducted to determine the haemodynamic response elicited by laryngoscopy and ETT and compare it with that elicited by LMA in ASA I (American Society Anesthesiologist) and ASA II patients, undergoing elective surgeries at Manipal Teaching Hospital. Results: The change in hemodynamic parameters after laryngoscopy and ETT insertion were significantly greater than those elicited by LMA (p<0.0001). The increase took about 5 minutes to return to pre insertion values in the ETT group, whereas about 3 minutes in the LMA group. It took a significantly shorter time to insert an LMA (12.63 sec) compared to ETT (22.76 sec). Conclusion: The haemodynamic changes elicited by LMA are less and short lived compared to those elicited by laryngoscopy and ETT insertion. It takes a shorter time and is much easier to insert an LMA compared to ETT.

System Objective

Background Laryngeal mask airway insertion causes less changes of haemodynamic parameters. As haemodynamic changes during laryngoscopy and endotracheal intubation as result of intense stimulation of sympathetic nerves system. Objective To find out the effective airway management by LMA during controlled ventilation, to avoid laryngoscopic and intubation induced haemodynamic changes and to avoid laryngospasm and bronchospasm. Method A total number of 100 patients ASA grade I & II were selected randomly as per inclusion and exclusion criteria in two groups. Fifty in each group. In group A used LMA and in group B used ETT during general anaesthesia in intermediate duration of gynaecological operation. Pulse,NIBP,SpO2 were recorded in perioperatively. Result Pulse, blood pressure were significant between the two groups (p<0.00) but in SpO2 was insignificant except in 2 min of intraoperative which was significant. (p<0.013). Conclusion LMA insertion causes less changes of haemodynamic parameters when compared with that of ET intubation. Our finding suggests that LMA can be safe and beneficial alternative to ETT.
