Overview
The laboratory finding scene in patients with a heat stroke include hypophosphatemia, hypokalemia, hypoglycemia, tension of arterial carbon dioxide is usually less than 20 mm Hg. Respiratory alkalosis is seen in non-exertional heat stroke where as lactic acidosis and respiratory alkalosis in exertional heat stroke.[1]
Laboratory Findings
The following laboratory findings may be noticed in a patient with heat stroke:[1][2][3]
| ||||||||||||||||||||||||||
- The tension of arterial carbon dioxide is usually less than 20 mm Hg
- Respiratory alkalosis in non-exertional heat stroke
- Lactic acidosis and respiratory alkalosis in exertional heat stroke
- Hypophosphatemia
- Hypokalemia
- Hypoglycemia (rare finding)
- Laboratory findings secondary to hemoconcentration
- Elevated creatinine kinase
- Elevated AST and ALT
Laboratory Findings after Cooling in Exertional Heat Stroke
