title: Epidural anaesthesia and analgesia for surgery: still going strong?
abstract: OBJECTIVE
  The discussion on the value of epidural anaesthesia and analgesia for surgery is fuelled by current controversies regarding effects on postoperative morbidity and mortality, potential benefits for outcome and the fear of rare, but catastrophic neurological complications. This review of the most recent publications on the topic since April 2002 illustrates some of the aspects contributing to the ongoing discussion.
  
  
  RESULTS
  In contradiction to previous meta-analyses, recent trials could not demonstrate significant improvements of overall morbidity or mortality by epidural anaesthesia and analgesia. However, the technique was shown again to provide superior analgesia and a reduction of perioperative stress response and respiratory complications. Analysis of the current literature strongly supports that epidural anaesthesia and analgesia remains a safe practice with a low rate of severe complications, in particular in paediatric surgery. Several developments in equipment, techniques and especially drugs have been reported, resulting in improved balanced anaesthesia and analgesia and contributing to the safety of this technique.
  
  
  CONCLUSIONS
  In an era of evidence-based medicine, further meta-analyses and well-planned large randomized trials have to address the controversial issues of epidural anaesthesia and analgesia and postoperative outcome. In the context of a more holistic 'rehabilitative' management of the perioperative period, this technique might well represent a key factor to improve outcome, reduce hospital stay and thereby healthcare costs. Recent innovations and developments in techniques and drugs as well as established guidelines should further minimize potential errors and harmful complications.
