A prospective study on fact embolism showed that of ninety-five patients
with a fractured shaft of the femur, seven (7 percent) demonstrated both
pulmonary and cerebral disturbances, while there were profound
disturbances in arterial PO2, hemoglobin level, pulse rate, and temperature
in about 40 per cent of the patients. Using a modified Gurd test, a
significant amount of fat was demonstrated in 5.7 per cent of the samples
of venous blood and in 18.5 per cent of the samples of arterial blood.
