Efficacy and safety of dexmedetomidine for analgesia and sedation in neonates: a systematic review.

Opioids and benzodiazepines have historically been employed for pain relief; however, they are associated with detrimental long-term neurodevelopmental consequences. Dexmedetomidine, a highly selective alpha-2-adrenoreceptor agonist, has piqued interest as a viable alternative for neonates, owing to its potential analgesic and neuroprotective attributes. We conducted a systematic review to assess the efficacy and safety of dexmedetomidine utilization in neonates. We conducted a comprehensive search of Ovid, MEDLINE, EMBASE, PubMed, Cochrane, and CINAHL, spanning from January 2010 to September 2022. Our review encompassed six studies involving 252 neonates. Overall, dexmedetomidine may be effective in achieving sedation and analgesia. Furthermore, it may reduce the need for adjunctive sedation or analgesia, shorten the time to extubation, decrease the duration of mechanical ventilation, and accelerate the attainment of full enteral feeds. Notably, no significant adverse effects associated with dexmedetomidine were reported. Nevertheless, additional well-designed studies to establish both the efficacy and safety of dexmedetomidine in neonatal care are needed.
