A Comprehensive Review of Fluid Resuscitation Strategies in Traumatic Brain Injury

Area of Science:

• Neuroscience
• Critical Care Medicine
• Trauma Surgery

Background:

• Severe traumatic brain injury (TBI) management aims to prevent secondary brain injury by optimizing cerebral perfusion pressure (CPP).
• Hypotension and cardiac dysfunction are frequent in TBI patients, necessitating fluid and vasopressor treatment.
• Fluid osmolarity is critical; hypotonic fluids may worsen cerebral edema, while hyperosmolar therapy is not recommended for resuscitation.

Purpose of the Study:

• To review current management strategies for severe TBI, focusing on resuscitation fluids and transfusion protocols.
• To evaluate the role of fluid osmolarity and blood transfusion strategies in TBI management.
• To emphasize the importance of hemodynamic and multimodal neurological monitoring in TBI care.

Main Methods:

• Review of current clinical practices and recent randomized clinical trials concerning TBI resuscitation.
• Analysis of fluid resuscitation categories (crystalloids, colloids, blood products) and their impact on TBI.
• Discussion of transfusion strategies (liberal vs. restrictive) based on individual physiological parameters.

Main Results:

• Hypotonic fluids are associated with an increased risk of cerebral edema in TBI patients.
• Hyperosmolar therapy is not beneficial as a resuscitation fluid in TBI.
• Optimal blood transfusion strategies require tailoring to individual patient parameters, with ongoing evaluation of liberal versus restrictive approaches.

Conclusions:

• Resuscitation fluid choice and osmolarity are critical in severe TBI management.
• Individualized blood transfusion strategies are necessary, informed by ongoing research.
• Hemodynamic and multimodal neurological monitoring are essential for guiding TBI resuscitation and improving outcomes.
