Abstract
|
|
|
Increases in heart rate and blood pressure are common during light planes of anesthesia at the end of operation and just prior to extubation. Increases in heart rate and blood pressure produce an elevation in cardiac work and oxygen demand and in patients with cardiovascular disease, can lead to myocardial ischemia. This study was undertaken to investigate and compare blood pressure and pulse rate responses to endotracheal extubation during awake and anesthetized.
Forty patients who received elective operation under general anesthesia were selected and divided into two groups, such as followings. group I: awake extubation group II: anesthetized extubation The results were as followings 1) systolic, Diastolic pressure and mean arterial pressure during and 1 minute after extubation were significantly increased in both group. but in group II, the degree of increment was reduced. 2) Heart rate and rate pressure product during and 1 minute after extubation were significantly increased in both groups I suggest that anesthetized extubation may alleviate the cardiovascular responses.
