Abstract

Outcomes of neonatal encephalopathy (NE) have improved since the widespread implementation of therapeutic hypothermia (TH) in high-resource settings. While TH for NE in term and near-term infants has proven beneficial, 30-50% of infants with moderate-to-severe NE treated with TH still suffer death or significant impairments. There is therefore a critical need to find additional pharmacological and non-pharmacological interventions that improve the outcomes for these children. There are many potential candidates; however, it is unclear whether these interventions have additional benefits when used with TH. Although primary and delayed (secondary) brain injury starting in the latent phase after HI are major contributors to neurodisability, the very late evolving effects of tertiary brain injury likely require different interventions targeting neurorestoration. Clinical trials of seizure management and neuroprotection bundles are needed, in addition to current trials combining erythropoietin, stem cells, and melatonin with TH. IMPACT: The widespread use of therapeutic hypothermia (TH) in the treatment of neonatal encephalopathy (NE) has reduced the associated morbidity and mortality. However, 30-50% of infants with moderate-to-severe NE treated with TH still suffer death or significant impairments. This review details the pathophysiology of NE along with the evidence for the use of TH and other beneficial neuroprotective strategies used in term infants. We also discuss treatment strategies undergoing evaluation at present as potential adjuvant treatments to TH in NE.

摘要

新生儿脑病 (NE) 的治疗结果在高资源环境中广泛应用治疗性低温 (TH) 后有所改善。虽然 TH 治疗足月和近足月婴儿的 NE 已被证明是有益的,但接受 TH 治疗的中重度 NE 婴儿仍有 30-50%死亡或存在严重损伤。因此,迫切需要寻找其他可改善这些儿童预后的药理学和非药理学干预措施。有许多潜在的候选药物;然而,当与 TH 联合使用时,这些干预措施是否有额外的益处尚不清楚。虽然原发性和迟发性(继发性)脑损伤在 HI 后的潜伏期开始是导致神经功能障碍的主要原因,但三级脑损伤的晚期演变效应可能需要针对神经修复的不同干预措施。除了目前正在进行的将促红细胞生成素、干细胞和褪黑素与 TH 联合应用的试验外,还需要进行癫痫管理和神经保护综合治疗的临床试验。 影响:治疗性低温 (TH) 在新生儿脑病 (NE) 治疗中的广泛应用降低了相关发病率和死亡率。然而,接受 TH 治疗的中重度 NE 婴儿仍有 30-50%死亡或存在严重损伤。本文详细介绍了 NE 的病理生理学,以及 TH 和其他用于足月婴儿的有益神经保护策略的应用证据。我们还讨论了目前正在评估的治疗策略,作为 NE 中 TH 的潜在辅助治疗。
