Shock is a major preventable cause of morbidity and mortality in children referred to emergency care. The recently updated American College of Critical Care Medicine guidelines for the management of newborns and children with septic shock emphasize the role of emergency care in improving survival and functional outcomes. Implementation of these guidelines of stepwise use of fluids, antibiotics, and, if necessary, inotropes within the first hour of admission to the emergency department can reduce mortality and neurological morbidity risks 2-fold. Therapies should be goal directed to maintain age-specific threshold heart rates and blood pressure as well as a capillary refill of less than 3 seconds or 2 seconds or less. Inotropes should be delivered through peripheral intravenous or intraosseous access when central access is unavailable because delay in inotrope delivery can greatly increase mortality risks. Emergency care systems should be organized to facilitate recognition, triage, and treatment of shock in the first hour. Emergency departments should be stocked with ready access to antibiotics, fluids, and inotrope infusions, and clinicians should be trained in the delivery of goal-directed fluid, antibiotics, and inotrope therapies in the first hour of resuscitation. For newborns, in addition to fluids, antibiotics, and inotropes, a prostaglandin infusion should be available within 10 minutes if duct-dependent congenital heart disease is a possibility.
休克是转诊至急诊科的儿童发病和死亡的一个主要可预防原因。最近更新的美国危重病医学会关于新生儿和儿童感染性休克管理的指南强调了急诊护理在改善生存和功能结局方面的作用。在急诊科入院后第一小时内逐步使用液体、抗生素以及必要时使用血管活性药物实施这些指南,可将死亡风险和神经疾病风险降低两倍。治疗应以维持特定年龄的心率和血压阈值以及毛细血管再充盈时间小于3秒或2秒或更短为目标。当无法进行中心静脉通路时,血管活性药物应通过外周静脉或骨内通路给药,因为血管活性药物给药延迟会大大增加死亡风险。应组织急诊护理系统,以便在第一小时内促进对休克的识别、分诊和治疗。急诊科应储备随时可用的抗生素、液体和血管活性药物输注剂,临床医生应接受在复苏第一小时内进行目标导向性液体、抗生素和血管活性药物治疗的培训。对于新生儿,除了液体、抗生素和血管活性药物外,如果有可能是依赖动脉导管的先天性心脏病,应在10分钟内备好前列腺素输注剂。
