Ensuring comfort for neonates undergoing therapeutic hypothermia (TH) after neonatal encephalopathy (NE) exemplifies a vital facet of neonatal neurocritical care. Physiologic markers of stress are frequently present in these neonates. Non-pharmacologic comfort measures form the foundation of care, benefitting both the neonate and parents. Pharmacological sedatives may also be indicated, yet have the potential to both mitigate and intensify the neurotoxicity of a hypoxic-ischemic insult. Morphine represents current standard of care with a history of utilization and extensive pharmacokinetic data to guide safe and effective dosing. Dexmedetomidine, as an alternative to morphine, has several appealing characteristics, including neuroprotective effects in animal models; robust pharmacokinetic studies in neonates with NE treated with TH are required to ensure a safe and effective standard dosing approach. Future studies in neonates treated with TH must address comfort, adverse events, and long-term outcomes in the context of specific sedation practices.
为患有新生儿脑病(NE)后接受治疗性低体温(TH)的新生儿提供舒适感,是新生儿神经重症护理的重要方面。这些新生儿经常出现应激的生理标志物。非药物性舒适措施是护理的基础,使新生儿和父母都受益。药物镇静剂也可能是必要的,但有可能减轻和加重缺氧缺血性损伤的神经毒性。吗啡是目前的治疗标准,具有使用历史和广泛的药代动力学数据,可指导安全有效的剂量。右美托咪定作为吗啡的替代品,具有一些吸引人的特点,包括在动物模型中的神经保护作用;需要对接受 TH 治疗的 NE 新生儿进行强有力的药代动力学研究,以确保安全有效的标准剂量方法。在接受 TH 治疗的新生儿中进行的未来研究必须根据具体的镇静实践,解决舒适度、不良事件和长期结局问题。
