Severe hyperphosphatemia associated with hemorrhagic shock.

G L Sternbach¹, J Varon

|July 1, 1992

Summary

Severe hyperphosphatemia can occur in hemorrhagic shock without kidney failure. Prompt treatment of shock and acidosis rapidly normalized phosphorus levels, likely via intracellular shifts.

Background:

Hyperphosphatemia, elevated serum phosphorus, typically results from impaired renal excretion.
Renal insufficiency is the most common cause of hyperphosphatemia.
Understanding non-renal causes of hyperphosphatemia is crucial for prompt diagnosis and management.

Observation:

A young male patient experiencing hemorrhagic shock developed severe hyperphosphatemia.
This occurred despite the absence of any signs of renal failure.
This represents a novel documented case of hyperphosphatemia secondary to hemorrhagic shock.

Findings:

The primary cause of hyperphosphatemia was identified as hypoperfusion and acidosis associated with hemorrhagic shock.
Rapid correction of hypoperfusion and acidosis led to a swift normalization of serum phosphorus (PO4) levels.
The mechanism for phosphorus normalization is hypothesized to be an intracellular shift of PO4.

Implications:

Physicians must consider hyperphosphatemia as a potential complication of hemorrhagic shock, even without renal insufficiency.
Recognizing this non-renal cause of hyperphosphatemia is important for appropriate clinical management.
Effective treatment of shock and its metabolic consequences can resolve this electrolyte disturbance.
