The observation of response to cardiovascular system at periextubation period after continuous epidural anesthesia combined with general anesthesia.

The observation of cardiovascular response at peri-extubation period after continuous epidural anesthesia combined with mild general anesthesia was studied. Fifty patients of carcinoma esophagus were randomly divided into two groups, general anesthesia + epidural anesthesia combined group and control group (only general anesthesia), each 25 cases in one group, using a multifunctional monitor, continuous monitoring and recording was done for ECG, systolic pressure (SP), diastolic pressure (DP), heart rate (HR), oxygen saturation (Spo2) and rhythm of heart during the peri-extubation period. Severe cardiovascular instability was detected in control group during peri-extubation period, especially at the time of extubation, even higher than the baseline values (p<0.
