Intracranial hypertension

This trial compares two common treatments—hypertonic saline and mannitol—to see which is better at reducing dangerously high pressure inside the skull after a severe traumatic brain injury. The study includes 100 adults with severe head injuries and uses a simple ultrasound measu…

This study tests whether setting a personalized 'optimal' blood pressure for each patient with severe traumatic brain injury reduces brain damage compared to standard fixed targets. Researchers will enroll 60 adults in the ICU and measure brain injury markers in the blood over fi…

Researchers are studying whether two bedside ultrasound techniques can help emergency doctors identify traumatic brain injury patients at risk of getting worse within 24 hours. The study enrolls 60 adults with acute traumatic brain injury and a low Glasgow Coma Scale score who ar…

This trial tests whether a bedside ultrasound of the eye can reliably detect raised pressure inside the skull, a condition that can damage the brain if not treated quickly. Researchers will measure the optic nerve sheath diameter in adults suspected of having high brain pressure …

This trial tests whether two non-invasive tools can help paramedics detect dangerously high pressure inside the skull in patients with sudden brain injury, such as stroke or head trauma, before they reach the hospital. The tools are a wearable sensor placed on the head and an ult…

This study explores whether ultrasound measurements of the eye can detect changes in brain pressure during laparoscopic gallbladder surgery. The surgery uses carbon dioxide gas to inflate the abdomen, which may affect pressure inside the skull. Researchers will compare two differ…

This study will test whether using ultrasound to guide how a patient's head is tilted can improve blood flow to the brain. Researchers will measure brain pressure and blood flow in 30 ICU patients as they are moved from lying flat to a 30-degree angle. The goal is to find a perso…

This trial tests whether remifentanil or esmolol is better at preventing dangerous pressure spikes in the brain when a breathing tube is inserted. Patients with unruptured brain aneurysms scheduled for coil embolization will receive one of the two drugs before intubation. Researc…

This study tests two strategies for removing an external ventricular drain (a tube that drains fluid from the brain) in 170 adults who had a brain bleed. One method clamps the drain shut as soon as it's safe, while the other gradually raises the drain over time. The goal is to se…

This study looks at whether placing a catheter in a neck vein changes pressure inside the skull. Researchers will use ultrasound to measure the optic nerve sheath and carotid artery in 61 adults under general anesthesia. The goal is to understand short-term effects, not to test a…

This study will test if a simple eye ultrasound can measure brain pressure in 60 adults before and after brain tumor surgery. The ultrasound looks at the optic nerve sheath diameter, which may change with pressure. If it works, it could offer a safer, non-invasive alternative to …

This study looks at how different gas pressures used during laparoscopic surgery for gynecologic cancers affect the optic nerve sheath diameter, which is a marker of pressure inside the skull. Researchers will measure this in 100 women aged 18-65 using ultrasound. The goal is to …
