有研究發(fā)現(xiàn)一種基于傳感器的非創(chuàng)傷性血壓檢查設(shè)備，是常規(guī)外科手術(shù)患者袖帶式和直接動(dòng)脈血壓檢查的可靠的替代選擇。

這項(xiàng)關(guān)于Vasotrac的研究在波士頓兒童醫(yī)院(MA, USA)由Mary E. McCann醫(yī)生和同事完成的。他們最終得出結(jié)論說：“接受接收麻醉的正常血壓兒童，在平臥狀態(tài)下和藥物誘導(dǎo)的低血壓狀態(tài)下，Vasotrac系統(tǒng)與動(dòng)脈內(nèi)血壓檢查的結(jié)果高度相關(guān)。”

根據(jù)這些研究結(jié)果，研究人員認(rèn)為Vasotrac系統(tǒng)是常規(guī)手術(shù)患者袖帶式和直接動(dòng)脈血壓檢查設(shè)備的可靠替代選擇。Vasotrac是Medwave公司(Danvers, MA, USA; www.medwave.com)的產(chǎn)品。該公司已經(jīng)在美國、歐洲和亞洲獲得了法律許可將該技術(shù)推向市場。幾種新產(chǎn)品已經(jīng)在全球超過500家醫(yī)院和診所中安裝使用。

在以前一例兒童患者因充血性心衰接受手術(shù)報(bào)道中，研究人員證實(shí)Vasotrac檢查結(jié)果與直接動(dòng)脈血壓監(jiān)測結(jié)果的一致性，但是當(dāng)時(shí)比較的是心臟手術(shù)后狀態(tài)穩(wěn)定的患者。新檢查比較的是接受脊柱側(cè)突手術(shù)的兒童，血壓波動(dòng)范圍較廣、手術(shù)失血以及不同患者體位等的多種情況。

Medwave公司總裁兼首席執(zhí)行官Tim O’Malley說：“我們研究了關(guān)于我們技術(shù)的正在投稿和已經(jīng)公布的在兒童患者、肥胖患者和急診科患者中使用我們系統(tǒng)的研究資料，迄今為止所有已經(jīng)完成的研究都提示我們的檢查技術(shù)表現(xiàn)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.”
