Comparative Study of Hemodynamic Responses to Airway Maintena nce Devices: Proseal LMA V/S IGEL Airway

Hemodynamic stress responses to tracheal intubation can precipitate adverse cardiovascular events in patients. In principal, techniques that avoid or minimise oropharyngolaryngeal stimulation might attenuate the hemodynamic stress response or reduce the incident of airway morbidity. We compared hemodynamic responses in 60 anaesthetized, paralyzed ASA-I and ASA-II patients among two airway maintenance devices: Proseal LMA (PLMA) and IGEL airway. Mean duration of insertion in each case of both groups was noted. Patients monitoring done for pulse rate, NIBP, ECG and SPO2 intraoperativly. Mean duration of insertion was significantly shorter in IGEL airway than PLMA. Changes in mean pulse rate were comparable in both groups. In mean arterial pressure, changes were significantly higher in group-I than group-II. No significant complication was noted in either group. It was concluded that IGEL is a better alternative airway maintenance device than PLMA because of ease of insertion and maintenance of hemodynamic stability.
