Although morphine and fentanyl remain the predominant epidural opioids, sufentanil offers some unique advantages. Because of its greater lipophilicity and mu-receptor binding capacity, sufentanil has a faster onset of action and longer duration than epidural fentanyl. Compared with morphine, sufentanil has been associated with a lower incidence of side effects, particularly delayed respiratory depression. The effective doses and adverse effects profile of epidural sufentanil are relatively well understood. Ventilatory depression is minimal with both bolus and continuous administration. Rapid vascular uptake after large epidural bolus, however, has been associated with acute-onset respiratory depression and even respiratory arrest. Sufentanil is more ideally suited than morphine to continuous epidural administration. The faster onset in comparison with fentanyl may make sufentanil the ideal agent for patient-controlled epidural analgesia. The synergistic effect of combined sufentanil and low-concentration bupivacaine offers advantages over sufentanil alone. High doses of epidural sufentanil have been uniquely associated with cessation of shivering and hypothermia. As with fentanyl, the intrathecal administration of sufentanil for postoperative analgesia is limited by its short duration of action.

The purpose of the present study was to determine the most effective time interval between the administration of sufentanil long acting (LA) and the induction of sevoflurane anaesthesia in dogs. The occurrence of sedation, analgesia and other marked side-effects were evaluated in addition to the possible dosage-reducing effect of sufentanil on sevoflurane in dogs. Forty clinically normal beagles aged 1-2 years and weighing between 8.4 and 13.6 kg were included. Two control groups were used: one group of dogs (A) received sufentanil LA (50 microg/kg i.m.) and a second group (B) the sufentanil vehicle followed by standard inhalation anaesthesia of 90 min. After premedication with sufentanil LA immediately before (C0), 15 min (D15) or 30 min (E30) prior to induction with thiopental (i.v.) the dogs were anaesthetized for 90 min with sevoflurane in oxygen. Pain and sedation scores were evaluated every 10 min during sevoflurane anaesthesia and at 2 (T120), 4 (T240) and 24 h (T1440) after initiation of anaesthesia. The occurrence of adverse reactions such as hypothermia, lateral recumbency, ataxia, noise sensitivity, vomiting, defaecation, salivation, nystagmus and excitation was observed at the same time-points. During the recovery period pain scores were lower and sedation scores higher in the sufentanil LA groups. In many dogs acceptable pain and sedation scores persisted during 24 h. Several dogs showed ataxia, lateral recumbency, arousal on auditory stimulation, defaecation, salivation and excitation at several time-points after sufentanil LA administration. Sufentanil LA in addition to sevoflurane anaesthesia offered beneficial dosage-reducing analgesic effects up to 69.8% for thiopental and 78.3% for sevoflurane; although several typical opioid side-effects occurred. To achieve this advantageous dosage-reducing effect 15 min should be respected between sufentanil LA administration and induction of sevoflurane anaesthesia.
