喂养不耐受早产儿静脉营养补钾时机的临床分析

Clinical Analysis of Feeding Intolerance in Preterm Children Timing of Intravenous Nutrition Potassium

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 investigate the premature infants with feeding intolerance intravenous nutrition supplement of potassium time.Methods From 2013 May to 2014 May in our hospital of 135 preterm infants with feeding intolerance,were randomly divided into study group 68 cases and control group with 67 cases.The control group in late preterm infants potassium,study group of premature infants were born early potassium supplement, seventh,14 days after detection of serum potassium levels.Results Study on the serum potassium level of seventh days group were significantly higher than control group,low potassium levels were significantly lower than the control group,the difference was statistically significant（P〈0.05）;no adverse reactions occurred in 1 cases.Conclusion Supplementary feeding intolerance in preterm children physiology of potassium in the 3d required may be effective in preventing the occurrence of hypokalemia.
