Multicenter Study Observational Study
Metamizole for postoperative pain therapy in 1177 children: A prospective, multicentre, observational, postauthorisation safety study.
Due to possible serious adverse drug reactions (ADRs), the use of metamizole for postoperative pain therapy in children is a subject of debate. Safety studies with large sample sizes have not been published as yet. ⋯ Single intravenous doses of metamizole used for the prevention or treatment of postoperative pain were well tolerated in more than 1000 children aged up to 6 years. The probability of serious ADRs (haemodynamic, anaphylactic or respiratory reactions) is lower than 0.3%. The sample size and follow-up was not sufficient to detect episodes of agranulocytosis.

Review Meta Analysis
Effects of melatonin premedication to prevent emergence agitation after general anaesthesia in children: A systematic review and meta-analysis with trial sequential analysis.
Emergence agitation is a common phenomenon in children recovering from general anaesthesia. An emergence agitation reaction increases the risk of injuring the surgical repair, the patient and the caregivers. ⋯ Compared with placebo, melatonin premedication may be effective in preventing emergence agitation in children (GRADE: low). This TSA suggests that further studies are required to confirm the results. Compared with midazolam, high-dose melatonin might have a significant effect in preventing emergence agitation (GRADE: very low). The study protocol was registered in the UMIN Clinical Trials Registry (registration number: UMIN000011841).

Randomized Controlled Trial Comparative Study
Preoxygenation by spontaneous breathing or noninvasive positive pressure ventilation with and without positive end-expiratory pressure: A randomised controlled trial.
In emergency situations requiring rapid airway control, shortening preoxygenate time is desirable. ⋯ Compared with spontaneous breathing, positive pressure ventilation with and without PEEP shortened preoxygenation time.

Clinical Trial Observational Study
Impact of preoperative fasting times on blood glucose concentration, ketone bodies and acid-base balance in children younger than 36 months: A prospective observational study.
In contrast to preoperative fasting guidelines in paediatric anaesthesia, actual fasting times are often too long. ⋯ After prolonged preoperative fasting, children younger than 36 months can present with ketoacidosis and (low) normal blood glucose concentrations. Actual fasting times should be optimised according to existing guidelines. In small infants, deviations from fasting guidelines should be as short as possible and not longer than 2 h.
