心内直视术后有创血压与无创血压监测的对照研究

A comparative study on invasive and non-invasive blood pressure monitoring for patients after underwent open heart operation

[目的]探讨心内直视术后早期有创血压与无创血压监测的差异。[方法]对30例心内直视术后病人进行24h连续的有创测压和无创测压监测,进行自身对照比较。[结果]有创血压和无创血压监测在心内直视术后早期8h内收缩压差异有统计学意义(P<0.001),8h后差异无统计学意义(P>0.05);舒张压差异无统计学意义(P>0.05)。[结论]心内直视术后早期采用有创血压监测,能提供更准确的依据,心内直视手术8h以后可以用无创血压监测替代有创血压监测。

Objective： To probe into the difference between invasive and non - invasive blood pressure monitoring for patients after underwent open heart operation in an early stage. Method： Blood pressure of 30 patients after underwent open heart operation were continuously monitored invasively or non- invasively for 24 hours, and the results of them compared with themselves. Result： There was a significant difference in systolic pressure between invasive and non- invasive blood pressure monitoring for patients within 8 hours after open heart operation （ P 〈 0. 001 ）. There was no difference between them after 8 hours （ P 〉0.05）. And there was no difference in diastolic pressure between invasive blood pressure and non- invasive blood pressure monitoring for them （P 〉0.05）. Conclusion： It could provide more accurate bases by monitoring blood pressure invasively at early stage after underwent open heart operation, and which could be replaced by non- invasive blood pressure monitoring 8 hours after open heart operation.
