Key result
The Dinamap ProCare 400 achieved an A/A grade in pregnancy and an A/B grade in preeclampsia compared to mercury sphygmomanometry, with mean systolic differences of 1.1 and -0.5 mmHg respectively.
Why the study?
Does the Dinamap ProCare 400 accurately measure blood pressure compared to mercury sphygmomanometry in pregnant women and those with preeclampsia?
Observational (n=45)
Yes
Does the Dinamap ProCare 400 accurately measure blood pressure compared to mercury sphygmomanometry in pregnant women and those with preeclampsia?
Effect estimate: Mean difference 1.1/0.1 mmHg (pregnancy) and -0.5/0.9 mmHg (preeclampsia) for systolic/diastolic
The Dinamap ProCare 400 meets British Hypertension Society accuracy standards for use in pregnancy and preeclampsia.
Supports automated BP validation in pregnancy; extends device data but leaves open prospective outcome trials before adoption.
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.

Greeff et al. (2010) conducted an observational in Pregnancy and preeclampsia (n=45). Dinamap ProCare 400 vs. Mercury sphygmomanometry was evaluated on Accuracy according to the British Hypertension Society protocol (Mean difference 1.1/0.1 mmHg (pregnancy) and -0.5/0.9 mmHg (preeclampsia) for systolic/diastolic). The Dinamap ProCare 400 achieved an A/A grade in pregnancy and an A/B grade in preeclampsia compared to mercury sphygmomanometry, with mean systolic differences of 1.1 and -0.5 mmHg respectively.
