| 摘 要： | 目的 探讨常规冠状动脉旁路移植术(CCABG)与非体外循环冠状动脉旁路移植术(OPCABG)围术期钾离子变化特点与补钾影响因素.方法 50例接受CABG患者,分为CCABG组和OPCABG组,每组25例.术中根据血气结果补钾,维持血清钾离子浓度在4.0～5.0mmol/L.记录并比较两组术中及术后液体出入量、补钾量、单位时间补钾量(补钾量/手术时间)、尿钾浓度、尿排钾量(总尿量×平均尿钾浓度)以及心肺转流(CPB)指标,分析两组术中补钾量的独立影响因素.结果 CCABG组术中补钾量及单位时间补钾量均高于OPCABG组,但其CPB前后单位时间补钾量低于OPCABG组(P＜0.05);CCABG组桥血管数、手术时间、术中尿量、尿排钾量及术后24 h补钾量均大于OPCABG组,术中平均尿钾浓度和最低体温低于OPCABG组(P＜0.05).多元线性回归分析显示尿量和入室血钾浓度是OPCABG组术中补钾量的独立影响因素;年龄和CPB转机时间是CCABG组术中补钾量的独立影响因素(P＜0.05).结论 CABG围术期需积极补钾.OPCABG中应根据基础血清钾水平结合尿量尽早开始补钾;CCABG中应根据CPB时间合理补钾.

| Abstract: | Objective To compare the change of plasma postassium and potassium supplement during conventional coronary artery bypass grafting(CCABG) and off-pump coronary artery bypass grafting(OPCABG).Methods Fifty patients undergoing CABG were randomly divided into two groups: CCABG group and OPCABG group,25 cases each.Potassium was administrated according to the results of blood gas analysis and the concentration of plasma potassium was maintained 4.0-5.0 mmol/L.The values of fluid infusion,urine output,the concentr... |
