BACKGROUND & AIMS: Feeding intolerance because of functional gastrointestinal dysmotility and parenteral nutrition-associated cholestasis (PNAC) are common problems in preterm, very-low-birth-weight (VLBW) infants. This double-blind, randomized, placebo-controlled study aimed to assess the effectiveness of "high-dose" oral erythromycin as a prokinetic agent in decreasing the incidence of PNAC. Two secondary end points, including the time to achieve full enteral feeding and the duration of parenteral nutrition, were also evaluated.
Infants consecutively admitted to the neonatal unit were randomized to receive erythromycin (12.5 mg/kg/dose every 6 hours for 14 days) or an equivalent volume of normal saline (placebo) if they attained less than half the total daily fluid intake (<75 mL/kg/day) as milk feeds on day 14 of life.
Of 182 VLBW infants enrolled, 91 received erythromycin. The incidence of PNAC was significantly lower in erythromycin-treated infants (18/91) compared with placebo infants (37/91; P = .003). Treated infants achieved full enteral nutrition significantly earlier (mean, 10.1; SE, 1.7 days; P < .001), and the duration of parenteral nutrition was also significantly decreased by 10 days (P < .001). Importantly, fewer infants receiving erythromycin had 2 or more episodes of septicemia (n = 4) compared with placebo patients (n = 13, P = .03). No serious adverse effect was associated with erythromycin treatment.
High-dose oral erythromycin can be considered as a rescue measure for VLBW infants who fail to establish adequate enteral nutrition and in whom anatomically obstructive pathologies of the gastrointestinal tract have been excluded.
由于功能性胃肠动力障碍导致的喂养不耐受以及肠外营养相关胆汁淤积(PNAC)是早产、极低出生体重(VLBW)婴儿常见的问题。这项双盲、随机、安慰剂对照研究旨在评估“高剂量”口服红霉素作为促动力剂在降低PNAC发生率方面的有效性。还评估了两个次要终点,包括实现完全肠内喂养的时间和肠外营养的持续时间。
连续入住新生儿病房的婴儿被随机分组,若在出生后第14天经口摄入的奶量少于每日总液体摄入量的一半(<75 mL/kg/天),则接受红霉素治疗(每6小时12.5 mg/kg/剂量,共14天)或等量生理盐水(安慰剂)。
在纳入的182例VLBW婴儿中,91例接受了红霉素治疗。与安慰剂组婴儿(37/91)相比,接受红霉素治疗的婴儿PNAC发生率显著更低(18/91;P = 0.003)。接受治疗的婴儿更早实现完全肠内营养(平均10.1天;标准误1.7天;P < 0.001),肠外营养的持续时间也显著缩短了10天(P < 0.001)。重要的是,与安慰剂组患者(n = 13)相比,接受红霉素治疗的婴儿发生2次或更多次败血症的情况更少(n = 4,P = 0.03)。红霉素治疗未出现严重不良反应。
对于未能建立充足肠内营养且已排除胃肠道解剖学梗阻性病变的VLBW婴儿,可考虑将高剂量口服红霉素作为一种补救措施。
