Abstract
Objective. To assess the accuracy of the Dinamap ProCare 400 in pregnancy and preeclampsia, according to the British Hypertension Society protocol. Methods. Ethical approval was obtained. Forty-five women were recruited at two large teaching hospitals. Nine sequential same arm measurements were taken from each woman alternating between the Dinamap and mercury sphygmomanometry. Results. The device achieved an A/A grade (pregnancy) and an A/B grade (preeclampsia). Mean difference (SD) were 1.1(5.8)/0.1(5.7) mmHg (pregnancy) and –0.5(5.4)/0.9(9.5) mmHg (preeclampsia) for systolic/diastolic. Conclusion. The Dinamap ProCare 400 is recommended for use in pregnancy and has good accuracy in preeclampsia, although caution is still advised.
