Study of hypertonic saline solution and mannitol to improve recovery in patients with traumatic brain injury and high risk of intracranial hypertension

3 1 1 1

What is this study about?

This clinical trial focuses on patients with traumatic brain injury, a condition where the brain is damaged due to external force or trauma. The study aims to evaluate whether giving a continuous infusion of hypertonic saline solution through a vein early in treatment can help improve survival and the ability to perform daily activities in patients who are at high risk of increased pressure inside the skull.

The study will use two treatments: sodium chloride solution and mannitol solution, both given through an intravenous line. These medications help control the pressure inside the brain after injury. Patients will receive treatment for up to 7 days while being monitored in an intensive care unit.

The study will track how well patients recover over time, particularly focusing on their survival after 3 months and their ability to perform daily activities independently after 6 months. Doctors will monitor various aspects of patient health, including salt levels in the blood and kidney function, to ensure the treatment is safe. The evaluation of how well patients recover will be done by medical professionals who do not know which treatment the patient received.

1 Initial admission and monitoring

You will be admitted to the intensive care unit within 12 hours of having a device placed to monitor your brain pressure

Your condition must meet specific criteria, including a Glasgow Coma Scale score of 12 or lower (a measure of consciousness level)

2 Treatment administration

You will receive either hypertonic saline solution or standard treatment through an intravenous line

The treatment will be administered continuously through your veins

Medical staff will monitor your brain pressure regularly

3 7-day monitoring period

During the first 7 days, medical staff will closely monitor your:

– Blood sodium levels

– Blood chloride levels

– Blood concentration (osmolarity)

Your treatment intensity will be assessed during this period

4 Follow-up at 1 month

Medical staff will check for any kidney problems

Your overall health status will be evaluated

You will complete a quality of life questionnaire

5 Follow-up at 3 months

Your survival and recovery progress will be assessed

You will complete another quality of life questionnaire

6 Final evaluation at 6 months

A specialist will evaluate your ability to perform daily activities

You will undergo cognitive function tests

Your overall recovery and independence level will be assessed

You will complete a final quality of life questionnaire

7 Extended follow-up at 12 months

Final survival assessment will be conducted

You will complete a final quality of life questionnaire

Your living situation will be documented

Investigated drugs:

Hypertonic Saline Solution (HSS) is a medical treatment that contains a higher concentration of salt (sodium chloride) than what is normally found in the body. When given through an intravenous (IV) line continuously, it helps reduce swelling in the brain that can occur after a traumatic head injury. This solution works by drawing excess fluid out of brain tissue, which can help decrease pressure inside the skull. This treatment is commonly used in intensive care units to manage patients with severe brain injuries.

Traumatic Brain Injury – A condition that occurs when an external force causes damage to the brain, disrupting its normal function. The injury typically results from a violent blow or jolt to the head, which can cause bruising, bleeding, or tearing of brain tissue. Brain tissue may swell following the injury, which can increase pressure within the skull. The condition can affect various brain functions including consciousness, memory, movement, and behavior. The effects may be temporary or long-lasting, depending on the severity and location of the injury.
