Randomized Controlled Trial Comparative Study Clinical Trial
Recovery after remifentanil and sufentanil for analgesia and sedation of mechanically ventilated patients after trauma or major surgery.
We investigated the analgesic effect and the neurological recovery time after administration of remifentanil in mechanically ventilated patients in an intensive care unit. Twenty patients, after trauma or major surgery with no intracranial pathology, were randomized to receive either remifentanil/propofol (n=10) or sufentanil/propofol (n=10). A sedation score and a simplified pain score were used to assess adequate sedation and analgesia. ⋯ During the following 20 min, all patients with remifentanil emerged from sedation and complained of considerable pain. By contrast, in the sufentanil group, only six (7) responded to commands after 10 (30) min and their pain score remained essentially unchanged during the 30-min observation period. We conclude that, in contrast to sufentanil, remifentanil facilitates rapid emergence from analgesia and sedation, allowing a clinical neurological examination within 10-30 min in mechanically ventilated patients with no intracranial pathology.

Intracranial subdural haematoma is an exceptionally rare complication of spinal anaesthesia. A 20-yr-old male underwent appendicectomy under partial spinal and subsequent general anaesthesia. A week later, he presented with severe headache and vomiting not responding to bed rest and analgesia. ⋯ The patient improved without surgical decompression. The pathogenesis of headache and subdural haematoma formation after dural puncture is discussed and the literature briefly reviewed. Severe and prolonged post-dural puncture headache should be regarded as a warning sign of an intracranial complication.
