ReviewIntranasal fentanyl in the treatment of acute pain--a systematic review.
Due to its non-invasive mode of administration, intranasal (IN) application of drugs may be a valuable alternative to non-invasive pain management. With characteristics that appear to be ideal for IN application, IN fentanyl may have a place in the out-of-hospital treatment and the paediatric population. The objective of this systematic review was to evaluate the current evidence of IN fentanyl in the treatment of acute pain. ⋯ In the paediatric population, results demonstrated some analgesic effect of IN fentanyl following myringotomy, no analgesic effect following voiding cystourethrography, and finally, no significant analgesic difference after long bone fractures, in burns patients, and in post-operative pain relief when compared to IV morphine, oral morphine, or IV fentanyl, respectively. Significant analgesic effect of IN fentanyl was demonstrated in the treatment of breakthrough pain in cancer patients. However, the significant deficiencies in trials investigating acute and post-operative pain, and the paediatric population makes firm recommendations impossible.

Reliability and validity of the Swedish version of the modified Yale Preoperative Anxiety Scale.
The modified Yale Preoperative Anxiety Scale (m-YPAS) is an observational behavioral checklist that has been widely used as an indicator of pre-operative anxiety in children. The present study describes the translation process of m-YPAS into Swedish and the testing of its reliability and validity when used with Swedish children. ⋯ This validation study of the Swedish version of the m-YPAS shows good consistency, interrater validity, and construct validity when used by experienced assessors.

Case ReportsInborn oxidative phosphorylation defect as risk factor for propofol infusion syndrome.
Propofol is an anesthetic agent widely used for induction and maintenance of anesthesia, and sedation in children. Although generally considered as reliable and safe, administration of propofol can occasionally induce a potentially fatal complication known as propofol infusion syndrome (PRIS). Mitochondrial dysfunction has been implicated in the pathogenesis of PRIS. ⋯ Five days after start of propofol infusion, the patient died. The activity of complex I of the oxidative phosphorylation (OXPHOS) system was severely deficient in skeletal muscle. Our observation indicates that fulminate PRIS can occur in an adult patient with an inborn OXPHOS defect and corroborates the hypothesis that PRIS is caused by inhibition of the OXPHOS system.

Xenon is not superior to isoflurane on cardiovascular function during experimental acute pulmonary hypertension.
Acute right ventricular afterload increase is a known perioperative challenge for the anaesthetic regime especially for patients with a compromised right ventricle. The accused negative inotropic action of volatile anaesthetics, with the exception of xenon, might be crucial for the adaptation of the right ventricle. ⋯ These results do not support the idea that xenon is more beneficial than isoflurane in right ventricular failure during pulmonary hypertension. Isoflurane did not compromise systolic ventricular function during acute PHT it only led to vasodilation in contrast to xenon.
