正压接头对经外周静脉置入中心静脉导管测中心静脉压的影响研究

Effects of positive pressure connector on central venous pressure testing by PICC

目的:探讨正压接头对经外周静脉置入中心静脉导管(peripherally inserted central catheter,PICC)测得中心静脉压(central venous pressure,CVP)值的影响,减少CVP的测量误差,为医护人员判断病人病情提供更准确的数据。方法:对我科51例进行PICC穿刺的病人在连接正压接头前、后进行CVP监测,行自身前、后对照,比较2组数据有无统计学差异。结果:连接正压接头前、后经PICC测得的CVP数值差异无统计学意义(P=0.417)。结论:正压接头对PICC测CVP的数值无明显影响,建议临床上通过正压接头进行CVP监测。

Objective：To explore the effects of positive pressure connector on central venous pressure（CVP）testing by peripherally inserted central catheter（PICC）,to reduce the measuring errors of CVP and to provide more accurate data for doctors. Methods：CVP of51 patients inserted PICC in our department before and after connecting positive pressure connector was measured and compared.Results：There was no significant difference in CVP data before and after connecting positive pressure connector（P=0.417）. Conclusion：Positive pressure connector exerts no significant effect on CVP testing by PICC and it is advised to measure CVP by PICC with positive pressure connector in clinics.
