To assess the agreement between manual auscultatory arterial blood pressure values and the values obtained by an automated oscillometric device in normotensive pregnant patients.
Arterial blood pressure was determined concomitantly by a Dinamap 1846 sx/p device and by one observer (I, IV, V Korotkoff sounds) blinded to the Dinamap values. Agreement between methods was tested and graded according to the protocol of the British Hypertension Society.
A total of 490 observations were performed. Differences were observed between the manual auscultatory method and the Dinamap method. In monitoring normotensive pregnant patients with a Dinamap device, an error was made of about 10 mmHg in 22% of the observations for systolic arterial blood pressure (BP); in 11% for diastolic arterial BP (IV sound); and in 15% for diastolic arterial BP (V sound). According to the British Hypertension Society protocol, the overall grade reached was 'C'.
Although an underestimation of only 10 mmHg was shown, this can be of great importance in delaying a correct diagnosis of pre-eclampsia. The assessment of agreement of the Dinamap 1846 sx/p device in hypertensive pregnant patients should also be determined. A prospective study could be useful to determine the effectiveness of an automated device in detecting hypertensive disease in pregnancy.
评估血压正常的孕妇手动听诊法测得的动脉血压值与自动示波装置测得的值之间的一致性。
使用Dinamap 1846 sx/p设备并由一名对Dinamap值不知情的观察者(听诊第I、IV、V期柯氏音)同时测定动脉血压。根据英国高血压学会的方案对两种方法之间的一致性进行测试和分级。
共进行了490次观察。手动听诊法和Dinamap法之间存在差异。在用Dinamap设备监测血压正常的孕妇时,22%的收缩期动脉血压(BP)观察值误差约为10 mmHg;11%的舒张期动脉血压(第IV期柯氏音)观察值误差约为10 mmHg;15%的舒张期动脉血压(第V期柯氏音)观察值误差约为10 mmHg。根据英国高血压学会的方案,总体分级为“C”级。
尽管仅显示出10 mmHg的低估,但这在延迟子痫前期的正确诊断方面可能非常重要。还应确定Dinamap 1846 sx/p设备在高血压孕妇中的一致性评估。一项前瞻性研究可能有助于确定自动装置在检测妊娠高血压疾病方面的有效性。
