HYPOTENSION

This study explores whether applying mild electrical stimulation to the spinal cord through the skin can improve blood pressure control in people with spinal cord injury. Participants will undergo tilt-table tests to measure immediate effects, plus 20 stimulation sessions to see …

This trial tests whether a newer anesthetic drug, ciprofol, causes fewer dangerous drops in blood pressure during anesthesia than the standard drug propofol in frail patients aged 60 and older having major abdominal surgery. Participants are randomly assigned to receive one of th…

This pilot study tests whether midodrine, a drug that raises blood pressure, can help heart failure patients with low blood pressure tolerate standard heart medications. About 56 hospitalized adults with weak heart pumps and low blood pressure will receive midodrine or usual care…

This pilot study tests whether a non-invasive brain stimulation technique called temporal interference can safely help regulate blood pressure. Researchers will enroll 25 adults with either mild untreated hypertension or hard-to-treat hypertension, as well as people with low bloo…

This study looks at whether measuring the collapsibility of the internal jugular vein in the neck using ultrasound can predict low blood pressure after general anesthesia. Researchers will measure the vein in 42 adults before gallbladder surgery and track blood pressure changes r…

This study tests whether applying mild electrical stimulation to specific acupoints on the wrist before anesthesia can prevent low blood pressure in older adults undergoing surgery. Researchers will compare high-frequency versus low-frequency stimulation in 84 participants aged 6…

This study tests a smartphone app called One.Dr to see if it can reduce the drop in blood pressure that happens when people with orthostatic hypotension stand up. About 86 adults who feel dizzy when standing will use either the real app or a sham version for 6 weeks. The goal is …

This study explores whether measuring how a woman's pupils react to light before spinal anesthesia can predict dangerous drops in blood pressure during planned cesarean sections. Researchers will observe 200 healthy pregnant women and track their pupil responses and blood pressur…

This study will follow 1,000 adults having a routine diagnostic endoscopy (camera test of the stomach or colon) with propofol sedation. Researchers want to find out which patients are more likely to have a dangerous drop in blood pressure or oxygen levels during the procedure. Th…

This study looks at how frailty—a state of weakness common in older adults—affects the risk of dangerously low blood pressure after anesthesia. Researchers will assess frailty in 80 elderly patients before surgery and track their blood pressure during anesthesia. The goal is to b…
