Evaluation of blood pressure is recommended in all children older than 3 years. Auscultatory devices are the recommended method to assess blood pressure in pediatrics, but automated oscillometric devices are increasingly common. A retrospective analysis of our school-based blood pressure screening was performed to determine if multiple oscillometric blood pressure measurements are needed to approach true blood pressure. All children had 4 oscillometric measurements of blood pressures and a random subset of 287 had an additional auscultatory measurement. Among 9870 participants, we observed a nonlinear decrease in blood pressure over time. The largest decrease in systolic blood pressure was between first and second (-3.8 mm Hg) and in diastolic from second to third (-3.3 mm Hg) measurement. For systolic blood pressure, the second oscillometric measurement, the average of second to third and the average of first to third were statistically similar to a single auscultatory measurement. We conclude that assessment of blood pressure using oscillometric devices should include at least 3 measurements in the same sitting to avoid inaccurate assessment.
建议对所有3岁以上儿童进行血压评估。听诊设备是儿科评估血压的推荐方法，但自动示波装置越来越普遍。我们对学校血压筛查进行了回顾性分析，以确定是否需要多次示波血压测量才能接近真实血压。所有儿童均进行了4次示波血压测量，随机抽取的287名儿童还进行了一次听诊测量。在9870名参与者中，我们观察到血压随时间呈非线性下降。收缩压下降最大的是在第一次和第二次测量之间（-3.8毫米汞柱），舒张压下降最大的是在第二次和第三次测量之间（-3.3毫米汞柱）。对于收缩压，第二次示波测量、第二次至第三次测量的平均值以及第一次至第三次测量的平均值在统计学上与单次听诊测量相似。我们得出结论，使用示波装置评估血压时，应在同一次就诊中至少进行3次测量，以避免评估不准确。
