The noninvasive oscillometric measurement of blood pressure (BP) in preterm neonates has become a common practice in intensive care nurseries. The method has gained acceptance primarily through its correlation with direct arterial measurement. In this study, the oscillometric method (using Dinamap 1846) was compared with direct intra-arterial BP monitoring in 15 preterm infants. The 95% prediction intervals for individual oscillometric measurements were wide, ranging from 17 mm Hg for the mean BP to 20 mm Hg for the systolic and diastolic BP. The oscillometric method also underestimated intra-arterial systolic and mean BP and overestimated diastolic BP. Caution must be used when oscillometrically measuring BP in premature neonates.
在重症监护病房中，对早产儿进行无创振荡式血压测量已成为一种常见做法。该方法主要因其与直接动脉测量的相关性而被接受。在本研究中，对15名早产儿采用振荡式测量法（使用Dinamap 1846）与直接动脉内血压监测进行了比较。个体振荡式测量的95%预测区间较宽，平均血压为17毫米汞柱，收缩压和舒张压为20毫米汞柱。振荡式测量法还低估了动脉内收缩压和平均血压，高估了舒张压。在对早产儿进行振荡式血压测量时必须谨慎。
