Summary
Hypertonic saline offers no proven benefit over isotonic solutions for trauma resuscitation. While it may help reduce intracranial pressure in traumatic brain injury (TBI) patients, evidence for improved outcomes is lacking.
Area of Science:
- Emergency Medicine
- Critical Care
- Trauma Surgery
Background:
- Trauma patients with hemorrhage, burns, or traumatic brain injury (TBI) are at risk of hypovolemic shock.
- Resuscitation is critical for managing shock and improving patient outcomes.
- Hypertonic saline is an alternative fluid resuscitation agent with potential hemodynamic and anti-inflammatory effects.
Purpose of the Study:
- To discuss the use of hypertonic saline in trauma patient resuscitation.
- To evaluate its efficacy in reducing intracranial pressure (ICP) in TBI.
- To review the existing evidence regarding its benefits and risks.
Main Methods:
- Review of existing literature, including randomized controlled trials and systematic reviews.
- Analysis of studies comparing hypertonic saline with isotonic crystalloids for trauma resuscitation.
- Examination of research on hypertonic saline's effect on ICP in TBI patients.
Main Results:
- Most studies show no significant difference in mortality or other outcomes between hypertonic saline and isotonic crystalloids for trauma resuscitation.
- Adequately powered trials investigating mortality endpoints were halted for futility.
- Some small studies suggest hypertonic saline may be more effective than mannitol for reducing ICP in TBI.
Conclusions:
- Current evidence does not support the routine use of hypertonic saline for trauma resuscitation over isotonic crystalloids.
- Hypertonic saline may have a role in reducing ICP in TBI patients, but further research is needed.
- Potential risks, such as central pontine myelinolysis, require careful monitoring.

01:16Tonicity in Animals
Tonicity describes the amount of solute in a solution. The measure of the tonicity of a solution, or the total amount of solutes dissolved in a specific amount of solution, is called its osmolarity. Three terms—hypotonic, isotonic, and hypertonic—are used to relate the osmolarity of a cell to the osmolarity of the extracellular fluid that contains the cells. In a hypotonic solution, such as tap water, the extracellular fluid has a lower concentration of solutes than the fluid inside the cell,...
01:21Cytotoxic Edema: Pathophysiology
Cytotoxic edema is a form of cerebral edema characterized by intracellular swelling of neurons, astrocytes, and other glial cells. It develops when the mechanisms responsible for maintaining ionic gradients across the cell membrane become impaired. Under normal physiological conditions, the sodium–potassium ATPase actively transports sodium ions out of the cell and potassium ions into the cell, preserving osmotic balance and enabling electrical signaling. This pump requires a continuous supply...
