: Compared with general anesthesia , neuraxial anesthesia may reduce the 0-to-30-day mortality for patients undergoing a surgery with an intermediate-to-high cardiac risk ( level of evidence moderate ) .
BACKGROUND : This analysis summarized Cochrane review s that assess the effects of neuraxial anesthesia on perioperative rates of death , chest infections , and myocardial infa rct ion .
Prospective, multi-centre trial of mortality following general or spinal anaesthesia for hip fracture surgery in the elderly.
In a prospect i ve r and omized multi-centre study , the mortality following internal fixation surgery for fracture of the upper femur was investigated in 538 elderly patients allocated to receive subarachnoid blockade or general ( narcotic-relaxant ) anaesthesia .  The 28-day mortality was 6.6 % with subarachnoid , and 5.9 % with general , anaesthesia . The difference was not significant ( 95 % confidence limits : -3.5 to + 4.8 ) . At 1 year following surgery , the mortality was 20.4 % . Increasing age , ischaemic heart disease , cardiac failure , preoperative arrhythmias and poor ASA status were all associated with increases in early and long term mortality . A delay to surgery of more than 24 h from admission was also associated with an increased 28-day mortality . Senile dementia and admission other than from the patient 's own home , were factors associated with a poorer long term outcome . From the point of view of mortality , subarachnoid anaesthesia did not appear to confer any advantages over general anaesthesia in non-prosthetic surgery for hip fracture in the elderly
