To review treatments for apnoea of prematurity (AOP).
Literature Review and description of personal practice.
Provided that symptomatic apnoea has been ruled out, interventions to improve AOP can be viewed as directed at one of three underlying mechanisms: (i) a reduced work of breathing [e.g. prone positioning, nasal continuous positive airway pressure (CPAP)], (ii) an increased respiratory drive (e.g. caffeine), and (iii) an improved diaphragmatic function (e.g. branched-chain amino acids). Most options currently applied, however, have not yet been shown to be effective and/or safe, except for prone, head-elevated positioning, synchronized nasal ventilation/CPAP, and caffeine.
Treatment usually follows an incremental approach, starting with positioning, followed by caffeine (which should be started early, at least in infants <1250 g), and nasal ventilation or CPAP via variable flow systems that reduce work of breathing. From a research point of view, we most urgently need data on the frequency and severity of bradycardia and intermittent hypoxia that can yet be tolerated without putting an infant at risk of impaired development or retinopathy of prematurity.
综述早产儿呼吸暂停(AOP)的治疗方法。
文献复习和个人实践描述。
只要已经排除了症状性呼吸暂停,改善 AOP 的干预措施可以被视为针对以下三个潜在机制之一:(i)呼吸功降低[例如俯卧位、持续气道正压通气(CPAP)],(ii)呼吸驱动增加(例如咖啡因),和(iii)膈肌功能改善(例如支链氨基酸)。然而,除了俯卧位、头高位、同步经鼻通气/CPAP 和咖啡因外,目前应用的大多数方法尚未被证明是有效和/或安全的。
治疗通常采用递增的方法,首先是体位,然后是咖啡因(至少在体重<1250 g 的婴儿中应尽早开始),然后是通过可变流量系统进行经鼻通气或 CPAP,以降低呼吸功。从研究的角度来看,我们最迫切需要关于早产儿能够耐受的心动过缓和间歇性低氧的频率和严重程度的数据,而不会使婴儿面临发育受损或早产儿视网膜病变的风险。
