Brief Summary

Postoperative agitation and emergence delirium describe a spectrum of symptoms of early postoperative negative behavior, in which the child experiences a variety of behavioral disturbances including crying, thrashing, and disorientation during early awakening from anaesthesia. The symptoms are common with a reported incidence of approximately 25%. Some clinical trials have studied the effect of prophylactic oral melatonin for reducing the risk of emergence agitation in children, some finding a considerable dose-response effect. Melatonin has a low bio-availability of approximately 15 %. The safety of exogenous melatonin for pediatric patients has been studied with no apparent serious adverse effects, even at repeated short-term use of high doses of intravenous melatonin. The aim of this clinical trial is to investigate the prophylactic effects and safety of intravenous melatonin administered intraoperatively for prevention of postopreative agitation and emergence delirium in children after an elective surgical procedure. The study is designed as a randomised, double-blind, placebo-controlled clinical trial.

Outcome Measures

Primary Outcomes (1)

  • Incidence of emergence agitation

    Participants will be assessed on Watcha scale repeatedly ever 15 min during their stay at the Post-Anesthetic Care Unit. The variable is dichotomous: any score \>2= "Yes" and no score \<=2 = "No"

    Up to approximately 4 hours corresponding to stay in Post-Anesthetic Care Unit (PACU).

Secondary Outcomes (2)

  • Opioid consumption

    Up to approximately 4 hours corresponding to stay in Post-Anesthetic Care Unit (PACU).

  • Non-serious Adverse Events (AE)

    From enrolment to the trial until 24-hour follow-up.

Other Outcomes (10)

  • Serious Adverse Events (SAE)

    SAEs will be assessed from enrolment until 30 days after intervention.

  • Postoperative pain

    Up to approximately 4 hours corresponding to stay in Post-Anesthetic Care Unit (PACU).

  • Postoperative nausea and vomiting (PONV)

    Up to approximately 4 hours corresponding to stay in Post-Anesthetic Care Unit (PACU).

  • +7 more other outcomes

Study Arms (2)

Melatonin

EXPERIMENTAL

Participants receive melatonin solution for injection 1 mg/mL in a dosage of 0.15 mg/kg body weight as a single intravenous injection approximately 30 minutes before end of surgical procedure.

Drug: Melatonin

Placebo

PLACEBO COMPARATOR

Participants receive isotonic sodium chloride (9mg/mL) intravenously once approximately 30 minutes before end of surgical procedure in a volume equivalent to the melatonin group for the same weight.

Drug: Isotonic sodium chloride solution

Interventions

Melatonin for injection 1 mg/mL

Melatonin

Sodium chloride 0.9 % for injection

Also known as: Normal saline
