Non-invasive techniques for measuring systolic blood pressure (BP) were evaluated in 10 very preterm infants, median gestational age 24 weeks, who were all of birthweight < or = 5750 g. Systolic BP measurements were attempted in all infants using a Doppler technique (Ultrasonic Doppler Flow Detector) and two oscillometers (Sentry and EME). Using each technique five separate measurements were attempted over a 10-min period. The systolic BP measurements for each device were then compared to results obtained from intra-arterial catheters which had an undamped waveform. BP measurements were possible on all 10 infants using the Doppler technique, but only in seven using the EME oscillometer and four using the Sentry oscillometer. The mean difference in measurements from those obtained using the arterial catheter were 0.27 mmHg using the Doppler technique and, in those infants in whom measurements were possible, 1.34 mmHg using the Sentry oscillometer and 1.34 mmHg using the Sentry oscillometer. We conclude that the Doppler technique provides the most useful and reliable non-invasive method of assessment of systolic BP in immature infants of birthweight < or = 750 g.
对10名极早产儿（中位胎龄24周，出生体重均≤5750g）的收缩压（BP）测量的非侵入性技术进行了评估。使用多普勒技术（超声多普勒血流探测器）和两种示波仪（Sentry和EME）对所有婴儿尝试进行收缩压测量。在10分钟内，使用每种技术尝试进行5次单独测量。然后将每个设备的收缩压测量结果与从具有无衰减波形的动脉导管获得的结果进行比较。使用多普勒技术，所有10名婴儿都可以进行血压测量，但使用EME示波仪时只有7名婴儿可以测量，使用Sentry示波仪时只有4名婴儿可以测量。使用多普勒技术时，与使用动脉导管获得的测量值的平均差异为0.27mmHg；在那些可以测量的婴儿中，使用Sentry示波仪时为1.34mmHg，使用Sentry示波仪时为1.34mmHg。我们得出结论，对于出生体重≤750g的未成熟婴儿，多普勒技术提供了评估收缩压最有用和可靠的非侵入性方法。
