婴幼儿腹部大手术后低钾血症对肠功能恢复的影响

Effects of Hypokalemia on Recovery of Intestinal Function in infants After Abdominal Operation

观察９８例小儿腹部大手术前后酸碱平衡、电解质变化及肠功能恢复情况，发现小儿腹部大手术后均存在明显低钾血症。术后第１天开始补钾较第３天开始补钾肠功能恢复快，手术后并发症少。对术后低钾血症的原因、输血对血钾的影响及手术后早期补钾的注意事项进行了讨论。

Before and after the abdominal operation, the changes of the electrolytes and the acid-base balance in blood, and the corresponding recovery of intestinal function were observed in 98 children with Hirschsprung's disease or congenital anorectal malformation. The results showed that hypokalemia appeared on the first day after operation; the intestinal function recovered sooner and the postoperative complication was less in patients who received intravenous potasium on the first day than those did on the third day after operation. The cause of hypokalemia, the effects of transfusion on blood potasium,and the early use of potasium were discussed.
