Nitroglycerin Versus Labetalol in Acute Severe Pre-eclampsia
Egypt200 participantsStarted 2019-08-28
Plain-language summary
Two hundred patients with severe PE were admitted prepartum to the ICU to stabilize blood pressure. They were randomly assigned to one of two groups (100 in each group): Group N received nitroglycerine intravenous infusion in a concentration of 1 mg/ml, thus 1µg/Kg/min equals to 4.8 ml/hr for an 80 Kg patient. Group L received labetalol intravenous infusion in a concentration of 10 mg/ ml, thus 50 mg/ml equals to 5 ml/hr. The starting infusion rate of the antihypertensive medication was 5 ml/hr. The infusion rate was titrated to stabilize systolic blood pressure (SBP) at 130-140 mmHg and diastolic blood pressure (DBP) at 80-90 mmHg (study end point) by adjusting the infusion rate as required either by maintaining the same infusion rate or by changing its infusion rate by 1 ml/hr up or down according to the clinical condition every 10 minutes. On any abrupt reduction in blood pressure below 120 mmHg for SBP or 80 mmHg for DBP, the infusion was immediately discontinued, and a bolus of 150 ml lactate ringer was given.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:Woman eligible for this study were aged between 18-40 years old at greater than 34 weeks of gestation having severe PE without severe features (without imminence of eclampsia or clinical manifestations of target organ damage, as per the ACOG criteria) (7). Severe PE was diagnosed by severe hypertension (systolic blood pressure ≥160 mmHg or diastolic blood pressure ≥110 mmHg, repeated measurement should be taken for confirmation no more than 15 minutes later), presence of clinically significant proteinuria (0.3 grams or more of protein in 24-hour urine collection, or urinary protein/creatinine ratio of 30 or more) -
Exclusion Criteria:patients with chronic hypertension, imminence of eclampsia, target organ damage, active asthma and congestive heart failure. Patients with any known allergy to one of the study drugs are also excluded.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
