早产儿两种喂养方法的比较研究

Comparative Study on Two Methods of Feeding Premature Infants

目的比较两种喂养方法用于早产儿的效果.方法早产儿共58例,出生体重在1 500～2 000 g范围内,随机分为甲、乙两组,甲组30例,乙组28例,甲组以微量泵通过鼻饲管持续均匀泵奶每小时2～3 ml,乙组则采用常规间歇鼻饲法,以注射器通过鼻饲管每2小时注奶4～6 ml,两组均观察3～5 d,比较观察期间两组患儿平均每天进奶量,吐奶例数、残奶例数等指标.结果甲组患儿平均每日喂奶量明显高于乙组(P＜0.05),且吐奶例数,残奶出现例数明显少于乙组(P＜0.05).结论早产儿采用微量泵鼻饲持续均匀泵奶效果明显优于常规间歇鼻饲喂奶法.

Objective To compare the effects of two methods of feeding premature infants. Methods 58 premature infants had been observed for 3--5days. Their birth weight was from 1500g to 2000g. They were divided into Group A （30 cases）and Group B（28 caese） randomly. Group A was fed 2 -3 ml milk every hour by stomach tubes with micro-infusion pumps continuously and symmetrically. Group B was fed 4-6 ml milk every two hours by nasal feeding regularly and periodically. The amount of digested milk and residual milk and time of disgorged milk of premature infants were compared. Results The amount of the milk fed infants in Group A was obviously more than that of Group B （P〈 0.05）. Besides, times of disgorging milk and amount of residual milk of infants in Group A were obviously less than those of infants in Group B （P 〈 0.05）. Conclusions Feeding milk for premature infants by stomach tubes with micro-infusion pumps continuously and symmetrically is much better than nasal feeding regularly and periodically.
