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.
