Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of clevidipine with sodium nitroprusside in the control of blood pressure after coronary artery surgery.
We set out to compare the efficacy of clevidipine and sodium nitroprusside infusions in the control of blood pressure and the haemodynamic changes they produce in hypertensive patients after operation for elective coronary bypass grafting. ⋯ There was no significant difference between clevidipine and sodium nitroprusside in their efficacy in controlling MAP. The haemodynamic changes, including tachycardia, were less pronounced with clevidipine than with sodium nitroprusside.

Randomized Controlled Trial Comparative Study Clinical Trial
Sedation for neuroradiology revisited: comparison of three techniques for cerebral angiography.
Previous work in our department, prior to the advent of digital subtraction angiography, showed that anaesthetist-administered sedation for cerebral angiography using propofol infusion-bolus fentanyl resulted in significantly more patients with early recall than a bolus fentanyl and midazolam technique. Our present study reassessed, 10 yr after our original study, the effectiveness of sedation for neuroradiological digital subtraction cerebral angiography, using three techniques currently in use in the department. ⋯ Our results show that since the introduction of digital subtraction angiography we may have a different end-point of sedation compared to our original study, as well as a shorter angiogram time. Satisfactory anaesthetist-administered sedation can be provided for cerebral angiography by either infusion or incremental techniques. We feel that the success and safety of a sedation technique depends considerably on the skill and experience of the administrator such that these sedation techniques are only suitable for safe use by an anaesthetist.

Randomized Controlled Trial Clinical Trial
Prospective, randomized, controlled evaluation of the preventive effects of positive end-expiratory pressure on patient oxygenation during one-lung ventilation.
This prospective, randomized, controlled study evaluated the effects on oxygenation by applying a selective and patient-specific value of positive end-expiratory pressure (PEEP) to the dependent lung during one-lung ventilation. ⋯ The selective application of PEEP to the dependent, non-operated lung increases the lung-chest wall compliance during one-lung ventilation, but does not improve patient oxygenation.

Randomized Controlled Trial Clinical Trial
Sufentanil added to hyperbaric bupivacaine for subarachnoid block in Caesarean section.
Subarachnoid block is a widely used technique for Caesarean section. Its quality can be improved by adding opioids to the local anaesthetics. We studied the quality of the block and its maternal-fetal repercussions when different doses of sufentanil were combined with hyperbaric bupivacaine using the intrathecal route in pregnant women undergoing Caesarean section. ⋯ The addition of sufentanil 5.0 and 7.5 microg to hyperbaric bupivacaine provided adequate anaesthesia for Caesarean section and good postoperative analgesia. Pruritus was the most common side-effect and had a significantly higher incidence when a dose of sufentanil 7.5 microg was used.

Randomized Controlled Trial Comparative Study Clinical Trial
Randomized comparison between sevoflurane anaesthesia and unilateral spinal anaesthesia in elderly patients undergoing orthopaedic surgery.
This prospective, randomized study was conducted to compare unilateral spinal block using small doses of hyperbaric bupivacaine and single-agent anaesthesia with sevoflurane in elderly patients undergoing hip surgery. ⋯ In elderly patients undergoing hemiarthroplasty of the hip, induction and maintenance with sevoflurane provide a rapid emergence from anaesthesia without more depression of postoperative cognitive function compared with unilateral spinal anaesthesia. This technique represents an attractive option when patient refusal, lack of adequate co-operation or concomitant anticoagulant therapy contraindicate the use of spinal anaesthesia.
