Preterm infants with bronchopulmonary dysplasia (BPD) have cardiorespiratory compromise that prolongs the transition time from gavage to nipple feeding. Heart rate variability (HRV) provides an indirect measure of the autonomic nervous system's influence on heart rate and cardiorespiratory stability. The purpose of this case study was to describe HRV responses of three preterm infants with BPD during the transition from gavage to nipple feeding. The infants responded to nipple feeding with increases in sympathetic influence on heart rate, and the increase continued in the 10-minute postfeeding. The infants were capable of balancing sympathetic and parasympathetic influences on heart rate related to the work of feeding.
患有支气管肺发育不良（BPD）的早产儿存在心肺功能受损，这会延长从管饲到直接哺乳的过渡时间。心率变异性（HRV）可间接反映自主神经系统对心率和心肺稳定性的影响。本病例研究的目的是描述 3 例患有 BPD 的早产儿从管饲到直接哺乳过渡期间的 HRV 反应。婴儿在开始直接哺乳时，心率的交感神经影响增加，并且在喂养后 10 分钟内持续增加。婴儿能够平衡与喂养相关的心率的交感神经和副交感神经影响。
