What specific type of fluid should be avoided in the case of traumatic brain injury?

• A. Hypertonic solutions like 3% Saline
• B. Isotonic solutions like Normal Saline
• C. Hypotonic solutions like 0.45% Normal Saline
• D. Colloids

Answer: (C)

Hypotonic solutions, such as 0.45% Normal Saline, should be avoided in cases of traumatic brain injury due to their potential to decrease serum osmolality. When hypotonic fluids are administered, they can lead to a decrease in the osmotic gradient between the bloodstream and brain tissue. This can contribute to the development of cerebral edema, or swelling in the brain, which is particularly detrimental in a patient with a traumatic brain injury. Maintaining an appropriate osmotic balance is crucial in such cases to prevent exacerbation of brain swelling and to protect neurological function. Therefore, isotonic and hypertonic solutions are often preferred because they help maintain intravascular volume and can assist in controlling intracranial pressure. Understanding this mechanism is vital for managing traumatic brain injuries effectively, as appropriate fluid management plays a critical role in patient outcomes.
