Pupil reflex test to predict low blood pressure in C-section
Part of Heart & circulation clinical trials.
This trial tests whether checking the pupil's response to light before spinal anesthesia can predict who will develop dangerously low blood pressure during a planned C-section. If it works, doctors could take steps to prevent it.
Summary written for real people, not researchers, by Clin2.

This trial uses an ultrasound measurement of blood flow in the neck to predict if a pregnant woman will experience low blood pressure after receiving spinal anesthesia for a C-section. This could help doctors take steps to prevent it.
This trial looks at whether we can predict which pregnant women will have a sudden drop in blood pressure during a cesarean section. If you're a healthy pregnant woman with a full-term single baby, this study could help improve safety.
This study looks at whether certain simple measurements (called shock indexes) taken before your cesarean delivery can help predict if you might have a drop in blood pressure after you get spinal anesthesia. The goal is to help doctors take better care of moms like you during the surgery.
This trial tests whether a higher or lower dose of norepinephrine works better to treat dangerously low blood pressure that can happen during a C-section. If you are a healthy full-term mother having a planned C-section, you may be able to join.
This trial tests two different doses of the drug noradrenaline to see which works better at preventing dangerously low blood pressure after spinal anesthesia for a planned C-section. This is for women who are at least 37 weeks pregnant and within a certain weight and height range.
This research study uses ultrasound images of a neck vein to predict whether a pregnant person will experience low blood pressure during spinal anesthesia for a planned cesarean section. The goal is to help doctors identify and prevent this common side effect before it happens.
