Summary
Severe burn injuries disrupt fluid balance, potentially causing shock. Resuscitation requires ample isotonic fluids and possibly more potassium to prevent complications and maintain vital functions.
Area of Science:
- Trauma and Burn Care
- Fluid and Electrolyte Physiology
- Resuscitation Medicine
Background:
- Significant burn injuries cause severe fluid and solute shifts.
- These shifts lead to deficits in extracellular fluid and circulating volume, risking shock.
Purpose of the Study:
- To review evidence on optimal fluid resuscitation strategies post-burn.
- To assess the adequacy of current resuscitation formulas regarding water and electrolyte balance.
Main Methods:
- Literature review of evidence on burn resuscitation.
- Analysis of fluid and solute translocation mechanisms.
Main Results:
- Resuscitation requires substantial water, ideally isotonic regarding sodium.
- Current formulas may be insufficient in potassium, impacting intracellular-extracellular solute balance.
- Most formulas effectively restore water balance, renal function, and cardiac output.
Conclusions:
- Optimal burn resuscitation involves large volumes of isotonic fluids.
- Potassium supplementation may be necessary in current resuscitation regimens.
- Established formulas are generally effective in preventing and correcting burn shock.
