AbstractSufentanil, an opioid analgesic, is an analogue of fentanyl, and has been used for the induction and maintenance of anaesthesia, and for postsurgical analgesia. It has shorter distribution and elimination half-lives, and is a more potent analgesic than fentanyl. In clinical practice, however, intravenously administered sufentanil produces essentially equivalent anaesthesia to fentanyl and is a better anaesthetic than morphine or pethidine (meperidine) for major surgery. It would appear to maintain haemodynamic stability during surgery better than other opioids or inhalational anaesthetics. Postoperative respiratory depression has been reported in a few patients. For outpatient surgery, intravenous sufentanil produces equivalent anaesthesia to isoflurane or fentanyl. Recovery tends to be more rapid after sufentanil and the requirement for postoperative analgesia is less. Initial clinical trials with sufentanil administered epidurally to relieve pain during labour have produced encouraging results, but further studies are required to establish the drug's role in this indication. Epidural sufentanil produces a more rapid onset and better initial quality of analgesia than morphine, buprenorphine or hydromorphine when administered postoperatively, but the duration of analgesia is shorter. Thus, sufentanil's primary place in therapy at this time would appear to be as high dose anaesthesia for major surgery such as cardiac surgery, and as low dose supplement to balanced anaesthesia in general surgery. In addition, low doses administered epidurally seem to have a potential role for analgesia during labour or after surgery although further studies are required to clarify this situation.
