Medwave公司推出新型血压检测设备

 
有研究发现一种基于传感器的非创伤性血压检查设备，是常规外科手术患者袖带式和直接动脉血压检查的可靠的替代选择。

这项关于Vasotrac的研究在波士顿儿童医院(MA, USA)由Mary E. McCann医生和同事完成的。他们最终得出结论说：“接受接收麻醉的正常血压儿童，在平卧状态下和药物诱导的低血压状态下，Vasotrac系统与动脉内血压检查的结果高度相关。”

根据这些研究结果，研究人员认为Vasotrac系统是常规手术患者袖带式和直接动脉血压检查设备的可靠替代选择。Vasotrac是Medwave公司(Danvers, MA, USA; www.medwave.com)的产品。该公司已经在美国、欧洲和亚洲获得了法律许可将该技术推向市场。几种新产品已经在全球超过500家医院和诊所中安装使用。

在以前一例儿童患者因充血性心衰接受手术报道中，研究人员证实Vasotrac检查结果与直接动脉血压监测结果的一致性，但是当时比较的是心脏手术后状态稳定的患者。新检查比较的是接受脊柱侧突手术的儿童，血压波动范围较广、手术失血以及不同患者体位等的多种情况。

Medwave公司总裁兼首席执行官Tim O’Malley说：“我们研究了关于我们技术的正在投稿和已经公布的在儿童患者、肥胖患者和急诊科患者中使用我们系统的研究资料，迄今为止所有已经完成的研究都提示我们的检查技术表现十分良好。”

Alternative Blood Pressure System
 
A study has found that a sensor-based, noninvasive blood pressure measuring device is a reliable alternative to cuff and direct arterial blood pressure measurement during routine surgery cases.

The study on Vasotrac was conducted at the Children’s Hospital of Boston (MA, USA) by Mary E. McCann, M.D. and colleagues. Their collective conclusion stated that “Our data suggest that the Vasotrac system correlates closely with intra-arterial blood pressure monitoring in anesthetized children under normotensive conditions in the prone position and during pharmacologic-induced hypotension.”

Based on these results, the researchers concluded that Vasotrac is a reliable alternative to cuff and direct arterial blood pressure measurement during routine surgical cases. Vasotrac is the product of Medwave, Inc. (Danvers, MA, USA; www.medwave.com). The company has received regulatory clearance to market its technology in the United States, Europe, and Asia. To date, a number of versions are installed in more than 500 hospitals and clinics worldwide.

In a previous report on children who had congenital cardiac surgery, the investigators had demonstrated agreement between the Vasotrac measurements and those obtained from direct intra-arterial blood pressure monitoring, but that comparison was performed once patients were in stable condition after cardiac surgery. The new test was performed to test Vasotrac in children undergoing scoliosis surgery, under wide blood fluctuations, surgical blood loss, and in a different patient position.

“We have had studies presented and published regarding the use of our technology with pediatric patients and obese patients, and in emergency medicine environments,” noted Tim O’Malley, president and CEO of Medwave. “All completed studies thus far have rendered positive results in which our technology has performed extremely well.”
