Abstract: 【Abstract】〓Objective〓To investigate the correlation between electrolyte changes and different types of operations by blood gas analysis, so as to provide some clues for early interventions. Methods 995 surgical cases were collected in the Sun Yat-sen Memorial Hospital from January 2012 to April 2013. The arterial blood samples of patients undergoing different types of operations were collected and sent for blood gas analysis by ABL800 analyzer at the beginning of the operations. Different type of electrolyte disorders occurred in different types of operations were noted,and statistic analysis were made by SPSS 13.0. Results〓Hypokalemia,hyperkalemia,hypocalcaemia,and hypercalcemia were correlated with the types of operations (P<0.05), while the association between serum sodium disorders and the types of operations was not significantly different(P>0.05). Hypokalemia and hypocalcemia were common seen in hepatobiliary surgical cases,gastrointestinal surgical cases and gynecological surgical cases. Otherwise, the association between ages and the types of electrolyte disorders was not significantly different (P>0.05). Conclusion〓Perioperative electrolyte disorders were closely related to the types of operations. More attention should be paid to electrolyte changes of patients undergoing hepatobiliary surgery,gastrointestinal surgery or gynecological surgery so that we can correct the electrolyte disorders in time.

摘要： 【摘要】〓目的〓研究手术开始时血气分析及电解质变化与不同手术类型之间的相关性,为预测不同类型的手术患者出现相应的电解质紊乱和及早采取干预措施提供一定的参考依据。方法〓收集中山大学孙逸仙纪念医院2012年1月~2013年4月的肝胆、胃肠、妇科等不同类型的手术病例共995例,其血气分析均由ABL800血气分析仪完成,分别统计不同类型手术患者发生电解质紊乱的情况。结果〓不同手术类型发生相应电解质紊乱的比例不一,经SPSS 13.0统计学软件分析,其中低钾血症、高钾血症、低钙血症和高钙血症与手术类型有相关性(P<0.05),而血钠紊乱与手术类型的相关性无统计学意义(P>0.05)。肝胆、胃肠、妇科等手术中以低钾血症和低钙血症多见。各种类型电解质紊乱与年龄因素的相关性无统计学意义(P>0.05)。结论〓围手术期血气分析电解质紊乱与手术类型密切相关,与年龄因素无关。肝胆、胃肠和妇科等较大手术应重视血气分析检查及电解质紊乱预测,做到及早诊断,及时纠正。
