目的 :探讨儿童腹部大手术后早期补钾对防治术后低钾血症的效果 ,并观察其对促进肠功能恢复的作用。方法 :80例消化道择期手术患儿随机分为甲、乙两组各 4 0例 ,甲组术后当日开始补钾 ,乙组按传统方法术后第 3天开始补钾 ,分别比较两组术前、术后第 1,3 ,5天血清钾、尿排钾量以及肠功能恢复情况。结果 :两组手术后血清钾均较术前降低 ,尿排钾量增加 ,术后当日补钾者较第 3天开始补钾者低血钾状态纠正快 ,肠蠕动恢复早。结论 :儿童腹部大手术后早期补钾可预防和治疗术后低钾血症 ,促进肠功能恢复。
Objective: To investigate the effect of early potassium supplement on the prevention and treatment of postoperative hypokalemia in children with major abdominal surgery, and to observe its effect on promoting intestinal function recovery. Methods: Eighty children undergoing elective surgery were randomly divided into two groups, 40 cases in each. Patients in group A started to receive potassium on the day after operation, and group B received potassium supplement on day 3 after operation. Preoperative, postoperative 1, 3, 5 days of serum potassium, urinary potassium output and intestinal function recovery. Results: After operation, the serum potassium in both groups decreased compared with that before operation, and the urinary potassium excretion increased. On the day after the operation, potassium supplementation was quicker to correct hypokalemia than that on the third day, and the peristalsis recovered earlier. Conclusion: Early potassium supplementation after major abdominal surgery in children can prevent and treat postoperative hypokalemia and promote recovery of intestinal function.
