经鼻持续正压气道通气(NCPAP)在极低体重儿治疗延长期经常用到。为了验证NCPAP是否对胃排空有影响,对16名平均体重935 g(s=155)、平均胎龄27.7 周(5=1.9)的早产儿进行NCPAP以及经胃管喂养。对照组为20名平均体重1 090 g(s=130)、平均胎龄28.2 周(s=1.2)的婴儿,未接受NCPAP。所有婴儿给予8 100 kcal/L的配方奶,而且奶量基本相同。使用超声检查技术对胃窦进行扫描。NCPAP治疗组,其胃窦的平均半量排空时间为28 min(s=12)。对照组为40 min (s=17),P<0.05。两组间在胃肠并发症的发生方面无差别。NCPAP治疗过的新生儿胃排空时间相对较短。
Nasal continuous positive airway pressure (NCPAP) is commonly used in the treatment of very low birth weight children. To verify whether NCPAP has an effect on gastric emptying, 16 preterm infants with an average body weight of 935 g (s = 155) and a mean gestational age of 27.7 weeks (5 = 1.9) were enrolled in a NCPAP and gastric feeding tube. The control group consisted of 20 infants with an average body weight of 1090 g (s = 130) and a mean gestational age of 28.2 weeks (s = 1.2) without receiving NCPAP. All infants gave 8 100 kcal / L formula, and the amount of milk is basically the same. Antrum examination is performed using ultrasound. In the NCPAP group, the average half-time of gastric antrum emptying was 28 min (s = 12). The control group was 40 min (s = 17), P <0.05. There was no difference in the incidence of gastrointestinal complications between the two groups. NCPAP-treated neonates have a relatively short period of gastric emptying.
