To evaluate the usefulness of noninvasive blood pressure monitoring during thoracic surgery, blood pressure measurements obtained with the Finapres 2300 (Ohmeda, Boulder, CO) were compared with an intraarterial catheter system in 10 patients undergoing thoracotomy for lobectomy or pneumonectomy. The Finapres measurements were compared with pressure data obtained ipsilaterally from a radial artery catheter-transducer system. The waveforms were recorded using a strip chart recorder; the systolic (SBP) and diastolic blood pressures (DBP) were measured every 20 seconds on the paper trace. Precision and bias were calculated for SBP and DBP for each patient and for the pooled data, with the invasive blood pressure being considered the gold standard. A total of 1,861 measurement pairs were recorded, 938 pairs during one-lung ventilation. The Finapres underestimated SBP during two-lung ventilation, and overestimated SBP during one-lung ventilation. The precision was good and the biases were small, but there were wide individual variations. It is concluded that the Finapres can be useful in estimating the variability and following the trends of radial arterial blood pressure during thoracic surgery, and is an acceptable alternative to invasive blood pressure monitoring.
为评估胸腔手术期间无创血压监测的实用性，我们将使用Finapres 2300（Ohmeda公司，科罗拉多州博尔德市）获得的血压测量值与10例接受开胸肺叶切除术或全肺切除术患者的动脉内导管系统测量值进行了比较。将Finapres测量值与从桡动脉导管-换能器系统同侧获得的压力数据进行比较。使用长条图记录仪记录波形；在纸质记录上每20秒测量一次收缩压（SBP）和舒张压（DBP）。计算每位患者以及汇总数据的SBP和DBP的精密度和偏差，将有创血压视为金标准。共记录了1861对测量值，其中938对在单肺通气期间记录。Finapres在双肺通气期间低估了SBP，在单肺通气期间高估了SBP。精密度良好且偏差较小，但个体差异较大。结论是，Finapres在估计胸腔手术期间桡动脉血压的变异性和跟踪其趋势方面可能有用，并且是有创血压监测的可接受替代方法。
