| 摘 要： | 目的:了解体外循环围术期血清及尿液中钾离子的变化规律,探讨合理的补钾用量和方法。方法:选取低温体外循环下心脏直视术的病人47例。于围术期各时点测红细胞比积、血清钾,同时测尿量、尿钾浓度。结果:围术期血清钾除停机及停机后15min时高于4.0mmol/L外,其余时间均低于4.0mmol/L。停机后钾离子主要通过尿丢失。结论:转流期间每10min补钾0.134mmol/kg的方式易引起机体缺钾。适当增加转流初期钾的补充量有利于防治转流中、后的低钾血症。

| Abstract: | Objectives To explore the change in serum and urine potassium during Cardiopulmonary bypass (CPB) and discuss the reasonable method of potassium supply. Methods Forty- seven patients undergoing open heart surgery with CPB were chosen randomly . HCT and potassium in serum and urine were measured during the perioperative phase. Result The serum potassium concentration was less than 4. 0mmol/L in perioperation except immediately and 15 minutes after terminating CPB . Conclusion During CPB 0.134 mmol/kg of potassium per 10 minutes administered could not maintain the serum potassium level over 4.0mmol/L . |
