All the following are true about Regional anesthesia Except
Davis et al. showed that spinal anesthesia decreases blood loss during hip replacement surgery. Christopher et al. showed that compared with general anesthesia, epidural anesthesia is associated with a lower incidence of reoperation for inadequate tissue perfusion and therefore main be advantageous for this surgical population. The paper showed 50 % reduction in the overall incidence of shivering in patients who received fentanyl, and there was some evidence to suggest that low-dose epidural fentanyl might reduce shivering by an influence on thermoregulation. Epidural analgesia with bupivacaine and morphine provided the best balance of analgesia and side effects while accelerating postoperative recovery of gastrointestinal function and time to fulfillment of discharge criteria in relatively healthy patients. The presence of epidural analgesia was associated with a significantly lower odds of death at 7 days.
Increases blood loss
Less complications after vascular surgery
Decreases Shivering after induction of anaesthesia
Less Complications after colon surgery
General anaesthesia
