不同输液速度对中心静脉压测量值的影响

目的探讨不同输液速度对中心静脉压(CVP)测量值的影响。方法将59例深静脉置管患者分别在常规中断输液(对照组)和以50mL/h(观察1组)、100mL/h(观察2组)、200mL/h(观察3组)、300mL/h(观察4组)速度连续输液5min后监测并记录CVP。结果五组CVP监测值比较,差异无统计学意义(P>0.05)。结论深静脉置管输入普通液体的患者,输液速度在300mL/h以内对中心静脉压测量值无显著影响。

Impact of varied infusion flow rates on central venous pressure

Objective To study whether varied infusion flow rates have an impact on central venous pressure(CVP).Methods Totally,59 patients with deep venous catheterization received infusion therapy.CVP measured at interruption of a routine infusion was taken as control.After that,infusion was resumed,with the flow rates being 50 mL/h,100 mL/h,200 mL/h,and 300 mL/h respectively,each for 5 min.Infusion was interrupted by CVP measurement after each 5 min interval.Results CVP measured at routine interruption,and measured at 4 flow rates had no significant difference(P>0.05). Conclusion The administration of common fluids through a deep venous line at a flow rate smaller than 300 mL/h does not affect CVP measurement.
