Randomized Controlled Trial Clinical TrialNeedle design does not affect the success rate of spinal anaesthesia or the incidence of postpuncture complications in children.
In adults, pencil-point spinal needles are believed to be less traumatic and therefore to be superior compared to cutting-point needles with respect to success rate and postpuncture complications. The aim of this randomised, parallel groups and prospective study was to record the success rate and to evaluate the incidence of complications following spinal anaesthesia with the two types of needles in children. ⋯ Both types of spinal needles can be used in children, and a free aspiration of CSF results in a high success rate of the spinal block. Postpuncture complications are as common in children as in adults.

Comparative StudyComparison of combined spinal epidural anesthesia and epidural anesthesia for cesarean section.
Epidural anesthesia (EA) is popular for cesarean section, but has some drawbacks such as incomplete block, inadequate muscle relaxation and delayed onset. Combined spinal epidural anesthesia (CSEA) has gained increasing interest as it combines the reliability of a spinal block and the flexibility of an epidural block. We investigated the efficacy of CSEA that combines the main spinal and the supporting epidural anesthesia, comparing with pH-adjusted EA, for cesarean section. ⋯ We can conclude that, when combining the main spinal and the supporting epidural anesthesia, CSEA has greater efficacy and fewer side effects than the pH-adjusted EA in cesarean sections.

Randomized Controlled Trial Comparative Study Clinical TrialCost comparison between three different general anaesthetic techniques for elective arthroscopy of the knee.
We compared three anaesthetic techniques for elective knee arthroscopy with special reference to cost-effectiveness. ⋯ From a cost-minimisation point of view, anaesthesia based on sevoflurane in oxygen:nitrous oxide is the technique of choice.

Coronary and systemic hemodynamic effects of clevidipine, an ultra-short-acting calcium antagonist, for treatment of hypertension after coronary artery surgery.
The aim was to evaluate the use of clevidipine, a new vascular selective, ultra-short-acting calcium antagonist for blood pressure control after coronary artery bypass grafting (CABG). ⋯ Clevidipine rapidly reduced MAP and induced a systemic, pulmonary and coronary vasodilation with no effect on venous capacitance vessels or HR. Clevidipine caused no adverse effects on myocardial lactate metabolism. Clevidipine thus appears suitable to control blood pressure after CABG.

Auditory evoked responses and learning and awareness during general anesthesia.
There is a major distinction between conscious and unconscious learning. Monitoring the mid-latency auditory evoked responses (AER) has been proposed as a measure to ascertain the adequacy of the hypnotic state during surgery. In the present study, we investigated the presence of explicit and implicit memories after anesthesia and examined the relationships of such memories to the AER. ⋯ The incidence of awareness in patients anesthetized with nitrous oxide and bolus supplementation was 6%. Thus, this anesthetic technique did not reduce the risk of awareness compared with the use of nitrous oxide alone. Implicit memory occurred during nitrous oxide and bolus supplementation. Recording AER during anesthesia may help to predict awareness and implicit memory, particularly the former. The short contents of most of the dreams which were recalled could hamper future studies in this area.
