Introduction:
Sedation of patients in pediatric ICU extubated and in weaning of mechanic ventilation is diffcult under regular sedation, because of the tolerance and/or abstinence generated by its sustained use. The objective of this study is to describe the use of Levomepromazine as sedative coadjuvant in these patients.
Population And Methods:
Observational and longitudinal study in intensive care from Juan P. Garrahan Pediatric Hospital. Patients older than 2 years were included, extubated and in weaning of mechanic ventilation with requirements of additional sedation. The level of basal sedation and post-intervention (levomepromazine 0.5 mg/kg every 8 hours) were evaluated with Ramsay and Khalil scales. Doses of regular sedatives were compared before and after the indication. It was considered positive an increase of 1 in the scales, or a decrease of 20% in the regular sedatives doses.
Results:
36 patients, medium age of 8,5 years, average doses of levomepromazine 0.38 mg/kg. 97% showed positive result. The regular sedative doses were reduced more than 20% after the intervention. No adverse effects or deceased were registered.

Sedatives and Hypnotics: Overview
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...

Benzodiazepines work by enhancing the effects of the inhibitory neurotransmitter GABA. They bind to the GABAA receptor, increasing its affinity for GABA, which opens chloride...
