Randomized Controlled Trial Clinical Trial
Enhanced pain management for postgastrectomy patients with combined epidural morphine and fentanyl.
To determine whether clinical advantages could be demonstrated by epidural fentanyl given in addition to epidural morphine for postgastrectomy analgesia. ⋯ The addition of 100 micrograms fentanyl to 2 mg or 4 mg epidural morphine provides clinical advantages over morphine alone for post-gastrectomy analgesia.

Randomized Controlled Trial Comparative Study Clinical Trial
Trial of three methods of intraoperative bupivacaine analgesia for pain after paediatric groin surgery.
To evaluate the relative effectiveness of three techniques of regional anaesthesia in the provision of postoperative analgesia in children. ⋯ All three methods achieved analgesia with 80% of the pain scores meeting our definition of satisfactory pain control. None of the techniques enjoyed any apparent advantage.

Randomized Controlled Trial Clinical Trial
Cardiovascular responses to tracheal extubation or LMA removal in normotensive and hypertensive patients.
This study was undertaken to evaluate the haemodynamic changes of tracheal extubation or removal of a laryngeal mask airway (LMA) in normotensive and hypertensive patients. ⋯ Removal of LMA is associated with less cardiovascular change than tracheal extubation in both normotensive and hypertensive patients.

Randomized Controlled Trial Clinical Trial
Interactions between nicardipine and enflurane, isoflurane, and sevoflurane.
During nicardipine induced hypotension, different inhalational anaesthetics may have different effects on haemodynamic variables, sympathetic function and drug metabolism. Therefore, the haemodynamic effects and pharmacokinetics of nicardipine were studied in the presence of the three inhalation anaesthetics enflurane, isoflurane and sevoflurane. ⋯ This study showed that the action of nicardipine is modified by different inhalational anaesthetic agents. Nicardipine has a prolonged duration of action in the presence of isoflurane and produces greater initial hypotension with sevoflurane.

Comparative Study Clinical Trial
Comparison of cerebral oximeter and evoked potential monitoring in carotid endarterectomy.
To assess the cerebral oximeter, which measures regional oxygen saturation (rSO2) continuously and noninvasively, as a cerebral monitor during carotid endarterectomy (CEA). The rSO2 was compared with Somatosensory Evoked Potentials (SSEPs) as an indicator for shunting and as a predictor of postoperative neurological deficits. ⋯ Clinical experience with this evolving technology is ongoing. Its role in neurovascular procedures has yet to be established.
