目的探讨喂养不耐受早产儿静脉营养补钾的时机。方法选取2013年5月至2014年5月我院收治的喂养不耐受早产儿135例,随机分为研究组68例和对照组67例。对照组早产儿晚期补钾,研究组早产儿早期补钾,均于出生后第7、14天检测血钾水平。结果研究组早产儿第7天的血钾水平明显高于对照组,低钾血症发生率明显低于对照组,差异均有统计学意义(均P<0.05);无1例不良反应发生。结论喂养不耐受早产儿于3 d内补充生理所需的钾,可有效预防低钾血症的发生。
Objective To explore the timing of feeding potassium nutrition in infants who are intolerant to premature infants. Methods From May 2013 to May 2014, 135 cases of intolerant premature infants admitted to our hospital were randomly divided into study group (68 cases) and control group (67 cases). In the control group, potassium was added in the late stage of preterm infants. In the study group, the potassium level in the early stage of preterm infants was detected at 7 and 14 days after birth. Results The serum potassium levels in the study group were significantly higher than those in the control group on the 7th day. The incidence of hypokalemia in the study group was significantly lower than that in the control group (all P <0.05). No adverse reaction occurred. Conclusion Feeding intolerant premature infants supplemented with physiologically needed potassium within 3 days can effectively prevent hypokalemia.
