Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This study is an open label randomized trial of women with antepartum hypertension. Women will be randomized to receive standard postpartum care or standard postpartum care without NSAIDs. Blood pressure measurements and patient outcomes will be recorded. The study period will begin at the time of delivery and will end at the time of hospital discharge.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This trial is a randomized, open label study investigating the effect of NSAID use on blood pressure during the immediate postpartum period in women with chronic hypertension (cHTN) or pregnancy induced hypertension (PIH). The experimental group in this study will be women randomized to withholding NSAIDs during the study period, as women with hypertension routinely receive NSAIDs postpartum. Women with a diagnosis of pregnancy induced hypertension \[gestational hypertension (gHTN), preeclampsia, superimposed preeclampsia, \] or cHTN will be enrolled antepartum and will be separated into two groups by the route of delivery: vaginal vs. cesarean delivery. Participants in the control arm will be assigned to receive standard care, which includes NSAIDs (ketorolac, ibuprofen) and participants in the experimental arm will be assigned to receive standard care with NSAIDs withheld in the postpartum period for the duration of hospitalization. The intervention period will last approximately 2-4 days and will conclude at the time of hospital discharge.
Blood pressure measurements will be obtained and recorded routinely in the postpartum period until hospital discharge. More frequent measurements may be performed in the event of severe blood pressure elevations at the discretion of the provider and treating clinical team. Complete Blood Count (CBC) on postpartum Day 1 will be performed as part of standard care. Additional laboratory evaluations will be performed at the discretion of the provider. In addition to blood pressure measurement, pain scale scores will be recorded daily using a Numeric Pain Scale Score. Initiation of anti-hypertensive medication, severe hypertension (BP 160/110 mmHg), treatment with magnesium sulfate and adverse maternal outcomes (cerebrovascular accident, congestive heart failure, pulmonary edema, eclamptic seizure, death) will be documented and abstracted from the medical record.
A power calculation to estimate the appropriate number of subjects needed to detect a difference of 30% in the primary outcome, with an alpha level of 0.05 and 80% power demonstrates that approximately 100 subjects per group (50 in the experimental group and 50 in the control group) will be needed for each delivery route tested (vaginal and cesarean).

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Standard Postpartum Care
Subjects will receive NSAIDs (e.g. ibuprofen, ketorolac) for routine postpartum pain management.
Ibuprofen 600 mg
Standard postpartum care (including administration of NSAIDs)
Standard Postpartum Care without NSAIDs
Subjects will receive standard postpartum care without NSAID administration for pain management. Acetaminophen or narcotics will be substituted for ibuprofen as indicated by provider.
Standard Postpartum Care without NSAIDs
NSAID administration will be withheld from this group.
