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.

Composition of the editorial/advisory boards of major English-language anesthesia/critical care journals.
Publications represent a central part of the research process. An analysis of who is responsible for acceptance of publications in major English-language anesthesia/critical care medicine journals was carried out. ⋯ Most editors/editorial board members of important Anesthesiology, Emergency and Critical Care journals came from the USA. Other countries play a significantly less influential role even in journals which are characterised as 'International Journals'.

Randomized Controlled Trial Comparative Study Clinical TrialContinuous epidural analgesia with bupivacaine-fentanyl versus patient-controlled analgesia with i.v. morphine for postoperative pain relief after knee ligament surgery.
Both epidural analgesia and intravenous patient-controlled analgesia (PCA) have been found efficacious after various types of surgery. We compared the efficacy, safety, side effects and patient satisfaction of these methods in a randomized double-blind fashion after elective anterior cruciate ligament reconstruction of the knee. ⋯ Epidural infusion of fentanyl (1 microg kg(-1) h(-1) or 0.5 microg kg(-1) h(-1)) and bupivacaine (0.1 mg kg(-1) h(-1)) provided better pain relief but more side effects than intravenous morphine patient-controlled analgesia after knee ligament surgery. Almost all patients in all groups were satisfied with their pain relief.

Randomized Controlled Trial Clinical TrialRecovery characteristics of sevoflurane or halothane for day-case anaesthesia in children aged 1-3 years.
Our objective was to compare the recovery characteristics of sevoflurane and halothane for short day-case anaesthesia in a specifically limited age group of children 1-3 yr. ⋯ In children 1-3 yr, sevoflurane provided more rapid early recovery but not discharge after anaesthesia of <30-min duration. Apart from more vomiting with halothane and more discomfort during the first 10 min after awakening with sevoflurane, the quality of recovery was similar with the two anaesthestics.

Randomized Controlled Trial Comparative Study Clinical TrialPlatelet dysfunction after intravenous ketorolac or propacetamol.
Paracetamol is a weak cyclo-oxygenase inhibitor in vitro. A recent study in children has shown that high doses of paracetamol are effective and safe. We studied the effect of propacetamol on haemostasis in adult volunteers. ⋯ Propacetamol 60 mg kg(-1) i.v. causes reversible platelet dysfunction demonstrated by a decrease in maximal platelet aggregation and TxB2 concentration. After 0.4 mg kg(-1) ketorolac i.v. platelet aggregation and TxB2 formation are inhibited more in comparison with propacetamol, and platelet dysfunction is still seen after 24 h.
