ABSTRACT
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<0.05). In combined group, the cardiovascular instability was far less, only a slight increase was noted at the time of extubation (p>0.05). The use of halothane was far less in combined group than that in control group (p<0.05). Mild general anesthesia combined with continuous epidural anesthesia is a good modality of anesthesia that can obviously decreased cardiovascular instability during peri-extubation.
