Prognostic factors in fresh water immersion.
The records of 63 consecutive fresh water immersion patients seen from 1969 to 1978 were examined retrospectively to evaluate those factors most relevant to the patients' eventual outcome. Nineteen patients had hematuria on admission, all 19 had complicated courses or died as a result of their immersion. Nine of the 63 patients had plasma hemoglobin concentrations of 30 mg/dl or above. Five of the nine died as a result of their immersion. The remaining four developed Adult Respiratory Distress Syndrome but survived. All other parameters measured seemed to have little effect on the prognosis. An elevation of PCO2 on admission seemed difficult to evaluate but might in certain circumstances suggest an ominous prognosis.
