HYPOTENSION

This study tests a device called the Hypotension Prediction Index (HPI) that warns doctors when a patient's blood pressure is about to drop dangerously low after surgery. 210 adults having elective surgery under general anesthesia will be randomly assigned to either standard moni…

This study tests whether giving a medicine called noradrenaline through a vein during surgery can prevent dangerous drops in blood pressure better than usual care. About 750 adults aged 45 and older having non-cardiac surgery will take part. The goal is to see if this approach re…

This study compares two drugs, norepinephrine and phenylephrine, given as continuous infusions to maintain blood pressure during planned C-sections under spinal anesthesia. 140 healthy pregnant women will receive one of the two drugs, and researchers will measure effects on the b…

This study looks at giving hydrocortisone, a steroid, to newborns with brain injury from lack of oxygen who are being cooled and have low blood pressure. Researchers want to find the best dose for each baby by measuring steroid levels in the blood. The goal is to safely raise blo…

This study tests whether a 5-minute mindfulness-based breathing exercise, done just before spinal anesthesia, can reduce the common drop in blood pressure and ease anxiety in women having a planned C-section. Half of the 150 participants will do slow, guided breathing (about 6 br…

This study compares two drugs, dexmedetomidine and dexamethasone, when added to a standard local anesthetic (ropivacaine) for a nerve block in the shoulder area. The goal is to see which combination provides faster pain relief for patients undergoing arm surgery. 66 adults aged 1…

This study compares two ultrasound-guided nerve blocks—supra-inguinal fascia iliaca block and pericapsular nerve group block—to see which one better reduces pain when positioning patients for spinal anesthesia during femur fracture surgery. Seventy adults with a broken femur will…

This study tests whether gentle electrical stimulation on the back can help stabilize blood pressure in people who recently had a spinal cord injury. Participants will undergo sit-up tests with and without stimulation to see if it prevents dizziness and keeps blood pressure in a …

This study tests whether mild electrical stimulation on the back can help stabilize blood pressure in people with chronic spinal cord injury who experience dizziness or fainting when sitting up. Five participants will have their blood pressure measured while tilted on a table, wi…

This study, called CEPEC, is a large platform trial enrolling 5,500 ICU patients across multiple countries. It tests different approaches to three common ICU treatments: how low to let blood pressure go with vasopressors, when to give platelet transfusions, and how to provide nut…

This study will collect routine data from 100 adult ICU patients to build a machine learning model that predicts low blood pressure (hypotension) up to 30 minutes before it happens. The model uses non-invasive vital signs, heart rate, medication records, and fluid balance. No tre…

This study looks at whether doctors can rely on feeling a patient's pulse (in the neck, groin, or wrist) to know if their blood pressure is dangerously low during shock. Researchers will compare pulse checks with standard blood pressure readings in 5,000 critically ill adults in …

This study is testing whether a continuous glucose monitor (CGM) designed for diabetes can work in intensive care patients with septic shock. Currently, nurses must prick patients' fingers every 2 hours to check blood sugar, which is painful and disruptive. The CGM uses a small s…

This study takes tissue samples from women having planned C-sections and tests four drugs (ephedrine, phenylephrine, norepinephrine, vasopressin) in a dish to see how they affect womb muscle and umbilical blood vessels. The goal is to understand which drugs might be safer for mot…

This study compares general anesthesia alone versus general anesthesia plus an epidural during pancreatic surgery. The goal is to see which method causes fewer drops in blood pressure and leads to better recovery. About 206 adults scheduled for surgery will take part.

This study looks at whether waist size, body mass index (BMI), and a heart-related index can predict low blood pressure after spinal anesthesia during cesarean sections. Researchers will measure 321 pregnant women before their scheduled C-section and track blood pressure changes.…

This study is testing whether measuring skin conductance—a sign of nervous system activity—can predict dangerous drops in blood pressure after spinal anesthesia in elderly cancer patients. Researchers will monitor 102 patients aged 65 and older undergoing urologic cancer surgery.…

This study tests two common blood-pressure-raising drugs, noradrenaline and phenylephrine, in 32 people undergoing brain tumor surgery. The goal is to see which drug better maintains blood flow and oxygen delivery to the brain and other organs. Researchers will use PET scans to m…

This study looks at different methods to predict whether giving IV fluids will help raise blood pressure in patients with impaired consciousness. Researchers will compare tests like ultrasound of the vena cava, leg raising, and fluid challenges in 222 ICU patients. The goal is to…
