Randomized Controlled Trial Comparative Study Clinical TrialAnalgesic efficacy and safety of preoperative versus postoperative ketorolac in paediatric tonsillectomy.
Tonsillectomy is a common procedure in childhood resulting in significant morbidity due to pain. The aim of this study was to evaluate the analgesic efficacy and safety of a single dose of ketorolac i.v. given before or after tonsillectomy, compared to placebo. ⋯ This study indicates that a single dose of ketorolac 1 mg.kg-1 i.v. administered either before or immediately after surgery improves postoperative analgesia in children after tonsillectomy without evidence of increased incidence of bleeding.

Randomized Controlled Trial Comparative Study Clinical TrialTotal intravenous anaesthesia with propofol and remifentanil in paediatric patients: a comparison with a desflurane-nitrous oxide inhalation anaesthesia.
Remifentanil is a new rapid-acting and ultra-short acting mu-opioid receptor agonist with few reports from use in children. Therefore, we compared a propofol-remifentanil-anaesthesia (TIVA) with a desflurane-N2O-anaesthesia (DN) with particular regard to the recovery of characteristics in children. ⋯ In children, TIVA with remifentanil and propofol is a well-tolerated anaesthesia method, with a lower peroperative heart rate and less postoperative agitation compared with a desflurane-N2O based anaesthesia.

Randomized Controlled Trial Clinical TrialPorcine-derived surfactant treatment of severe bronchiolitis.
It is hypothesized that surfactant treatment helps to improve severe bronchiolitis by restoring surfactant system activity. This study aims to assess the effect of surfactant on gas exchange, peak inspiratory pressure and duration of mechanical ventilation and intensive care unit (ICU) stay in children with severe bronchiolitis. ⋯ Surfactant treatment of severe bronchiolitis appeared to improve gas exchange, reduce PIP and shorten CPPV and ICU stay. However, these initial results must be confirmed by a larger and more rigorously controlled study.

Case ReportsAn unusual toxic reaction to axillary block by mepivacaine with adrenaline.
An increase in blood pressure, accompanied by atrial fibrillation, agitation, incomprehensible shouts and loss of consciousness, was observed in an elderly, ASA classification group II, cardiovascularly medicated male, 12 min after performance of axillary block with mepivacaine 850 mg containing adrenaline 0.225 mg, for correction of Dupuytren's contracture. After intravenous administration of labetalol, metoprolol and midazolam the patient's condition improved, and 15 min later he woke up. ⋯ Postoperatively, the patient refused DC cardioversion and was treated medically. Both the temporal relationship of events and the response to treatment suggest that a rapid systemic absorption of mepivacaine with adrenaline and/or interaction of these drugs with the patient's cardiovascular medications were responsible for the perioperative complications.

Randomized Controlled Trial Comparative Study Clinical TrialModified double burst stimulation of varying stimulating currents.
Using modified double burst stimulation (modified DBS), sufficient level of recovery from neuromuscular blockade (train-of-four (TOF) ratio > 0.7) can properly be diagnosed. Modified DBS may often be applied in awake patients in the postanesthetic care unit. As the stimulating current decreases, the neurostimulation-induced discomfort becomes less for awake subjects. It is relevant to investigate the usefulness of the modified DBS delivered at low currents. ⋯ Modified DBS-induced discomfort becomes less as the stimulating current decreases. However, when stimulated at 30 or 20 mA, fade in response to modified DBS is felt in too many cases, even after neuromuscular blockage subsides to an adequate level.
