Finding the best phenylephrine dose to prevent low blood pressure during cesarean delivery
Part of Heart & circulation clinical trials.
This study tests a medication called phenylephrine, which helps keep your blood pressure from dropping too low during spinal anesthesia for a planned cesarean section. It compares two positions—lying flat on your back versus tilted to the left—to find the best dose for preventing low blood pressure, which can affect you and your baby.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be pregnant with a single baby (not twins) and have a full-term pregnancy (at least 37 weeks).
- Your cesarean delivery must be planned (elective), not emergency.
- You must be between 150 and 180 cm tall (about 4'11" to 5'11").
- Your body mass index (BMI) must be below 35.
- You must be in generally good health (classified as ASA II or III, meaning mild to moderate health issues).
- You must not have certain conditions like high blood pressure, diabetes, preeclampsia, or fetal growth problems.

This trial tests two medicines given through an IV during a planned cesarean section to prevent a sudden drop in blood pressure (hypotension) after spinal anesthesia. One medicine is called metaraminol and the other is norepinephrine. Both are commonly used to keep blood pressure stable, and the goal is to find out which works better and is safer for mothers and babies.
This study compares two types of spinal anesthesia for planned cesarean sections to see which one causes less of a drop in blood pressure. It may help you and your doctor choose the safest option for your delivery.
This study looks at how a pregnant woman's body mass index (BMI) affects the dose of a medicine called norepinephrine, which is given during a cesarean section to prevent low blood pressure. The goal is to find the right dose for each woman to keep her blood pressure stable during the procedure.
This trial compares two medications, norepinephrine and phenylephrine, to see which works better at preventing low blood pressure during emergency C-sections under spinal anesthesia.
This study compares two medicines (norepinephrine and phenylephrine) given continuously through a vein to keep your blood pressure stable during a planned cesarean with spinal anesthesia. It aims to see which medicine works better for you and your baby.
This trial compares two medicines, norepinephrine and ephedrine, to see which one works better at keeping blood pressure stable during a planned C-section under spinal anesthesia. It will help doctors choose the safest option for mothers and babies.
