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 .
Epidural Anesthesia and Analgesia in High‐risk Surgical Patients
The authors conducted a r and omized controlled clinical trial to evaluate the effect of epidural anesthesia and postoperative analgesia ( EAA ) on postoperative morbidity in a group of high-risk surgical patients . A total of 53 patients were admitted to the study , 28 received EAA , and 25 received st and ard anesthetic and analgesic techniques without EAA . Surgical “ risk ” was evaluated preoperatively and found to be comparable in the two groups . When compared to control patients , patients who received EAA had a reduction in the overall postoperative complication rate ( P = 0.002 ) and in the incidence of cardiovascular failure ( P = 0.007 ) and major infectious complications ( P = 0.007 ) . Urinary cortisol excretion , a marker of the stress response , was significantly diminished during the first 24 postoperative hours in the group receiving EAA ( P = 0.025 ) . Finally , hospital costs were significantly reduced for patients who received EAA ( P = 0.02 ) . The authors conclude that EAA exerted a significant beneficial effect on operative outcome in a group of high risk surgical patients
