Objective In this study, we piloted the use of continuous 24-hour blood pressure (BP) monitoring in postpartum patients with preeclampsia with severe features.

Study Design We measured continuous BP for up to 24 hours using finger plethysmography. We also used an oscillometric device to measure brachial BP per usual clinical protocol (intermittent BP) during the same monitoring period. Using a paired t-test, we compared mean BP values assessed using intermittent and continuous methods, and using McNemar's test, we compared the proportion of patients with sustained severe-range BP using each BP measurement method.

Results A total of 25 patients were included in this study. There was no difference in mean systolic BP (SBP) and mean arterial pressure between intermittent and continuous BP measurements. Intermittently recorded mean diastolic BP (DBP) was significantly higher than continuously recorded DBP. Eleven participants (44%) had sustained SBP ≥160 mm Hg using continuous monitoring compared with two using intermittent monitoring (p = 0.003). Of these 11 participants, 3 (37%) also recorded sustained DBP ≥110 mm Hg using continuous monitoring compared with none using intermittent monitoring.

Conclusion Continuous BP monitoring is a feasible and reliable method for detecting sustained severe-range BP in postpartum patients receiving treatment for preeclampsia with severe features.

Key Points

Postpartum continuous BP monitoring is feasible.

Continuous BP detects more sustained severe BP.

Continuous BP may be a reliable BP method.
