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 0.05). 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.
