The administration of epidural opioids is alternatively used in the management of postoperative analgesia. However, the administration is associated with side effects, including respiratory depression, somnolence and pruritus. A rational opioid selection between the hydrophilic and lipophilic opioids morphine, hydromorphone, alfentanil, fentanyl and sufentanil is discussed in this mini-review. ⋯ The same holds true for alpha 2-adrenoceptor agonists as adjuvants. However, multicenter dose-ranging studies are necessary to determine both the ideal concentrations of the drug combinations and the general outcome. Moreover, we must also determine cost effectiveness for our postoperative analgesic techniques.

Many patients still suffer from unnecessary pain in the postoperative period. Waiting for new technologies or drugs will not improve the status of acute pain management. The establishment of an acute service is needed to reduce the incidence of postoperative pain. Acute pain therapy is one of the great challenges we have to take up.

Although the need for the implementation of a quality management concept for the German emergency medical system (EMS) has been discussed for more than 10 years, such a concept has not been realised on a broad scale. Standardised national data sheets were developed many years ago. They are used by many local agencies, but a data-gathering system on a state or national basis is still lacking. ⋯ Quality control works on the basis that all EMS team members are motivated to perform on a professional level to ensure that each patient is treated adequately. It evaluates the system to create circumstances that enhance the achievement of this goal. Quality management is not only concerned with mishaps, because areas with documented good performance also provide important information.

Effects of anaesthesia and analgesia on postoperative morbidity and mortality remain controversial. Numerous studies have demonstrated that epidural anaesthesia and pain relief by epidural analgesia reduces perioperative stress responses and thus may reduce postoperative morbidity and mortality. In patients undergoing vascular surgery, epidural anaesthesia diminished postoperative hypercoagulability. ⋯ One reason for this disappointing finding may be the missing integration of improved postoperative pain relief into general surgical care. A multimodal therapeutic approach, which consists of preoperative patient information, sufficient analgesia, early mobilisation and enteral feeding, may solve this discrepancy. Therefore, prospective controlled studies are needed to assess the influence of this perioperative approach on outcome.

Postoperative neurological sequelae in patients that have received epidural anaesthesia are not necessarily caused by the epidural anaesthetic technique. As a whole, adverse neurological outcomes following epidural anaesthesia may be subdivided into 3 different ethiological categories. A first category involves events that are not at all caused by the epidural, but merely due to the interference of anaesthesia and/or surgery with a preexisting medical condition. ⋯ These complications include some of the most dramatic sequelae of major neuraxial blockade, such as spinal epidural abscess, spinal infarction, and spinal hematoma. Although extremely rare, the latter complications often result in permanent major neurological deficits. The present manuscript is a review of the most recent, literature addressing post-anaesthetic sequelae, and will discuss their incidence, pathophysiology, clinical course, diagnosis, prevention, and treatment.
