Compared with general anaesthesia , a central neuraxial block may reduce the zero to 30-day mortality for patients undergoing surgery with intermediate to high cardiac risk ( level of evidence , moderate ) .
BACKGROUND Various beneficial effects derived from neuraxial blocks have been reported .
However , it is unclear whether these effects have an influence on perioperative mortality and major pulmonary/cardiovascular complications .
OBJECTIVES Our primary objective was to summarize Cochrane systematic review s that assess the effects of neuraxial blockade on perioperative rates of death , chest infection and myocardial infa rct ion by integrating the evidence from all such review s that have compared neuraxial blockade with or without general anaesthesia versus general anaesthesia alone for different types of surgery in various population s. Our secondary objective was to summarize the evidence on adverse effects ( an adverse event for which a causal relation between the intervention and the event is at least a reasonable possibility ) of neuraxial blockade .
Anaesthetic techniques for surgical correction of fractured neck of femur. A comparative study of ketamine and relaxant anaesthesia in elderly women.
Ketamine has been compared with ' relaxant ' anaesthesia in operations for fractured neck of femur in elderly women . Ketamine was found to reduce early mortality principally by a reduction in thromboembolic complications , but at the expense of more unsatisfactory surgical results . It is suggested that the mortality after relaxant anaesthesia for these operations is unacceptable
