目的：分析血气分析中动脉血和中心静脉血电解质指标的相关性。方法选取拟行中心静脉穿刺和桡动脉穿刺的麻醉患者72例，在全身麻醉诱导后10 min分别抽取动脉血和中心静脉血，使用GEM Premier 3000血气分析仪进行血气分析，对Na＋、K＋、Ca2＋浓度的测定值进行相关性分析。结果动脉血中Na＋：（138．81±2．40）mmol／L ，静脉血中Na＋：（139．90±2．39） mmol／L ，两者比较差异有统计学意义（P＜0．01）；动脉血中K＋：（3．92±0．42）mmol／L ，静脉血中K＋：（3．93±0．39）mmol／L ，两者比较差异无统计学意义（P＞0．01）；动脉血中Ca2＋：（1．30±0．04）mmol／L ，静脉血中Ca2＋：（1．32±0．05）mmol／L，两者比较差异有统计学意义（P＜0．01）。结论动脉血和中心静脉脉血血气分析中测定的Na＋、Ca2＋的离子浓度有明显差异，中心静脉血浓度略高于动脉血，而K＋的浓度无明显差异。

Objective To study the correlation between ion concentrations of arterial and central venous blood in blood gas anal‐ysis .Methods This prospective study was performed in 72 patients with a central venous catheter and an artery catheter .A central venous blood sample and an artery blood sample were obtained at the same time after 10 minutes′anesthesia induction .Correlation analysis of the ion concentrations such as Na+ ,K+ ,Ca2+ between those in arterial and central venous blood were performed .The ion concentrations were determined by using GEM Premier 3000 Blood Gas Analysis System .Results The concentration value of Na+ in artery blood was (138 .81 ± 2 .40)mmol/L and in central venous blood was (139 .90 ± 2 .39)mmol/L ,there was significant difference between them(P<0 .01) .The concentration value of K+ in artery blood was (3 .92 ± 0 .42)mmol/L and in central venous blood was (3 .93 ± 0 .39)mmol/L ,which were not significantly different(P>0 .01) .The values of Ca2+ in artery blood was (1 .30 ± 0 .04)mmol/L and in central venous blood was (1 .32 ± 0 .05)mmol/L ,which were significantly different(P<0 .01) .Conclusion There is significant difference between Na+ ,Ca2+ concentrations in arterial blood gas analysis and those in central venous blood gas analysis ,central venous blood is relatively higher than artery blood ,while no statistically significant difference is observed for K+concentration .
