ABSTRACT
Background: Anesthesia is quite remarkable and attenuation of pressor response is one of the most keenly researched subjects in the field of anaesthesiology, the reason being the non-availability of a ‘procedure/drug of choice’ for the same. Patients with arterial hypertension generally exhibit excessive pressor response to stress such as laryngoscopy, intubation, surgical incision and extubation, which can lead to arrhythmias, myocardial ischemia and cerebrovascular accidents. Exchange extubation with LMA Supreme can be used to overcome or blunt the excessive pressor response following extubation. Objective: To compare the hemodynamic changes during traditional awake extubation and extubation using LMA supreme in controlled hypertensive patients. Methods: The prospective study was carried out in the department of Anaesthesiology, Shaheed Tajuddin Ahmad Medical College Hospital, Gazipur, Bangladesh from January to December-2021. Fifty (50) patients were randomized by permuted blocks into two groups. After complete pre- anesthetic check-up and investigations. Controlled hypertensive patients with ASA (American Society of Anesthesiologists) grade II, between the age of 17 and 65 years, undergoing elective, non-oral surgery were included in the group. Hemodynamic stress response between traditional awake extubation of the endotracheal tube (ETT) and that following exchange extubation of ETT by using a laryngeal mask airway (LMA Supreme) in terms of Post Extubation Heart Rate (H.R), Systolic Blood Pressure (S.B.P), Diastolic Blood Pressure (D.B.P), Mean Arterial Pressure (MAP), to determine whether this method is easy to perform, the amount of experience needed to perform the exchange well and to calculate the time delay in extubation caused by adopting this method. Results: There was highly significant increase in pulse rate in Group A (ETT Group) as compare to LMA SupremeTM group, which was statistically significant till 15min. of extubation.
