Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialA comparison of anaesthesia using remifentanil combined with either isoflurane, enflurane or propofol in patients undergoing gynaecological laparoscopy, varicose vein or arthroscopic surgery.
Anaesthesia comprising remifentanil plus isoflurane, enflurane or propofol was randomly evaluated in 285, 285 and 284 patients, respectively, undergoing short-procedure surgery. ⋯ Anaesthesia combining remifentanil with volatile hypnotics or TIVA with propofol was effective and well tolerated. Times of extubation, postanaesthesia recovery and recovery room discharge were rapid, consistent and similar for all three regimens.

Randomized Controlled Trial Clinical TrialIntrathecal adenosine administration in abdominal hysterectomy lacks analgesic effect.
Adenosine (Ado) is known, from studies in both animals and humans, to produce antinociception when administered systemically or intrathecally (IT). The current aim was to evaluate, in a placebo-controlled, randomised, double-blind study, whether IT adenosine given before surgery could reduce anaesthetic requirement and the need of opioids during 48 h after visceral surgery. ⋯ IT adenosine did not influence the requirement of anaesthetic drug or postoperative analgesics after hysterectomy.

Clinical TrialRisk factors for postoperative anxiety in children.
Anxiety is defined as a set of behavioural manifestations that can be divided into state- and trait-anxiety. State-anxiety is a transitory emotional condition that varies in intensity and fluctuates over time. Trait-anxiety is a personality trait which remains relatively stable over time. The objective of this study was to identify and quantify perioperative risk factors for immediate postoperative anxiety in children. ⋯ High levels of preoperative state-anxiety, administration of less than 0.056 mg x kg(-1) of midazolam, absence of analgesic block and presence of moderate and intense postoperative pain constituted risk factors for immediate postoperative state-anxiety in children. Previous surgery reduced the risk for postoperative anxiety.

Case Reports Clinical TrialLow-dose prostacyclin in treatment of severe brain trauma evaluated with microdialysis and jugular bulb oxygen measurements.
The endogenous substance prostacyclin is a substance with the potential to improve microcirculation and oxygenation around contusions in the brain following a head trauma by its vasodilatory, antiaggregatory and antiadhesive effects. Microdialysis measurements of local concentrations of selected interstitial substances in the brain, and measurements of venous jugular bulb oxygenation reflecting overall brain oxygenation, might be useful to evaluate possible therapeutic effects of a specific therapy, such as treatment with prostacyclin. ⋯ The microdialysis data combined with the jugular bulb oxygenation data indicated that low-dose prostacyclin exerts effects compatible with improved oxygenation and reduced cell damage in the severely traumatised brain.

Case ReportsAnaphylactic reactions during induction of anaesthesia using rocuronium for muscle relaxation: a report including 3 cases.
Anaphylaxis during induction of anaesthesia is a dreaded complication with a mortality rate of 3-6%, most frequently associated with the use of muscle relaxants. Current knowledge on this matter is reviewed in relation to the presentation of 3 cases of anaphylaxis and bronchospasm associated with the use of the recently released nondepolarizing muscle relaxant rocuronium. Bronchospasm may be the sole sign of a serious drug reaction, triggered by precipitation of insoluble thiopental crystals when mixed with a muscle relaxant in the intravenous (iv) line. ⋯ It is recommended that serum tryptase is measured approximately 2 h after debut of the serious drug reaction. Allergy testing should be performed for all the drugs the patient was exposed to, 4-8 weeks after the incident, and due to cross-reactivity, including all available muscle relaxants. Doctors are urged to inform their patients, and systematically register adverse drug reactions.
