Randomized Controlled Trial
[Effects of epidural analgesia using different concentrations of bupivacaine during combined general and epidural anesthesia].
Thoracic epidural analgesia, combined with general anesthesia, is an established anesthetic choice for abdominal aortic surgery. However, there are controversies about the level of anesthesia as well as the dose and concentration of the local anesthetic used. The aim of the study was to compare the effects of two different concentrations of epidural bupivacaine on sevoflurane requirements and hemodynamic parameters during aortic surgery under combined epidural/general anesthesia. ⋯ When 0.5% bupivacaine is used in combined thoracic epidural/ general anesthesia for aortic surgery, the sevoflurane concentrations are lower and less variable. In addition, the blood loss and fluid requirements are reduced.
