Efficacy of Melatonin as a Sleep Inducer in EEG Procedures in the Pediatric Population: A Cross-Sectional Study

Introduction Melatonin has been used as an alternative to sleep deprivation for EEG sleep induction in the pediatric population. Our study aims to describe the efficacy of the currently used doses of melatonin for sleep induction among the pediatric age group. Methods A retrospective cross-sectional study included all patients who underwent an EEG after receiving melatonin over the period of one year. A total of 126 patients have been included in the study. Patients aged one year to three years received oral melatonin in doses between 2 mg and 6 mg. Patients in the age of three years and above received 10 mg of melatonin. Patients' success rate in achieving sleep and the exact time required for the patients to fall asleep were obtained using the readings of their EEG. The percentage of patients who have achieved sleep and the time required for those patients to sleep were calculated and correlated with the patient's gender, the presence of any associated neurobehavioral disorders, and their use of antiepileptic drugs (AED). Results Successful sleep was achieved in 84.9% (n:107) of the patients, with a mean time of 24 minutes to fall asleep (SD = 14.36). Patients with neurobehavioral disorders were 20% less likely to fall asleep when compared to other patients without neurobehavioral disorders (p: 0.003). However, there was not a statistically significant difference among different genders and among patients who received AED. Conclusion Melatonin is an effective sleep inducer for patients undergoing EEG procedures. It should be considered in the majority of patients. However, in patients with neurobehavioral disorders, a lower success rate is expected.
