So far , the evidence available from the studies included is insufficient to prove that neuraxial anesthesia is more effective and safer than general anesthesia for orthopedic surgery .
However , this systematic review does not rule out clinical ly important differences with regard to mortality , stroke , myocardial infa rct ion , length of hospitalization , postoperative cognitive dysfunction or pneumonia
CONTEXT AND OBJECTIVE Taking the outcome of mortality into consideration , there is controversy about the beneficial effects of neuraxial anesthesia for orthopedic surgery .
The aim of this study was to compare the effectiveness and safety of neuraxial anesthesia versus general anesthesia for  orthopedic surgery .
Mental function and morbidity after acute hip surgery during spinal and general anaesthesia
Forty elderly patients ( mean age 78.9 years ) undergoing acute surgery for hip fracture were given at r and om either spinal analgesia with bupivacaine 0.75 % or general anaesthesia with diazepam , fentanly and N2O/O2 . Mental function was studied pre‐operatively with an abbreviated mental test and 1 week and 3 months postoperatively in both groups . Mortality and number of complications was similar in the two groups , but a shorter time of ambulation was seen in the spinal group compared to the general anaesthetic group . No persistent impairment in mental function was found after acute hip surgery under spinal or general anaesthesia and the only advantage of regional technique was a shorter time of ambulation
