人工机械瓣置换术后有创血压与无创血压监测的对照研究

目的 探讨人工机械瓣置换术后有创动脉血压(ABP)与无创动脉血压(NBP)测量值的差异.方法 对40例机械瓣置换术后24 h患者进行有创和无创动脉血压监测比较,并对结果 进行t检验.结果 有创和无创动脉血压在术后早期(12 h内)比较差异显著,12 h以后比较无显著差异.结论 机械瓣置换术后早期的有创血压与实际血压值有一定误差,采用有创血压监测,能更准确的反映血压的真实值,心内直视手术12 h以后可以用无创血压监测替代有创血压监测.

A comparative study on invasive and non-invasive blood pressure monitoring for patients after me-chanic valve replacement

Objective To investigate the difference between invasive and non-invasive blood pres-sure monitoring for patients after mechanic valve replacement. Methods Invasive or non- invasive blood pressure of 40 patients after mechanic valve replacement were continuously monitored for 24 hours, and the results underwent t test. Results There was a significant difference between invasive and non-invasive blood pressure monitoring for patients within 12 hours after mechanic valve replacement, but no difference was seen between them after 12 hours. Conclusions It can provide more accurate bases by monitoring blood pressure invasively at early stage after mechanic valve replacement, and it can be replaced by non-invasive blood pressure monitoring 12 hours after mechanic valve replacement.
