摘要
目的进行急危重症患者中心静脉压测量系统效能评估体系的临床实证研究，探讨中心静脉压测量系统效能的影响因素。方法采用中心静脉压测量系统效能评估表对197例连续监测中心静脉压的急危重症患者进行监测，收集评价指标数据。比较分析中心静脉压测量系统效能的影响因素。结果三通开关数量、血管活性药、呼气末正压对中心静脉压测量系统效能具有显著影响，检验统计量值分别为8．557，-6．773和3．244，差异均具有统计学意义；不同体位患者的中心静脉压测量系统效能评估得分间比较差异无统计学意义。结论通过临床实证研究，验证了中心静脉压测量系统效能评估体系的实际应用价值和可操作性，探讨了中心静脉压测量系统效能的影响因素，为临床实践工作提供效能判断参考依据。
Objective We aimed to study the performance evaluation indicators of central venous pressure （CVP） measuring system for ICU patients in clinical trials and discuss its impact factors. Methods Ac-cording to the performance evaluation indicators of CVP measuring system based on the Delphi method, a form was created to evaluate the continuous CVP monitoring of 197 ICU patients and then the data were collected. A comparative analysis was performed to verify the factors affecting the performance of CVP mea- suring system. Results The performance of CVP measuring system was affected by the number of three- way switches, vasoactive drugs and positive end-expiratory pressure, the statistical value was 8.577, -6.773 and 3.244. There were no statistically significant differences with respect to performance evaluation indica- tors of CVP measuring system among the patients with different body positions. Conclusions The perfor- mance evaluation indicators of CVP measuring sys-tem proves to be feasible and practical by clinical em- pirical research. Their influencing factors were dis-cussed and they offer a valuable reference for the deter- mination of the performance of CVP measuring sys-tem in clinical practice.
