Embolies graisseuses post-traumatiques

Abstract

Between 1977 and 1982, fifty cases of post-traumatic fat embolism were treated in a general intensive care unit. Average age of patients was 25.5 ± 13 years; there was no male majority. Mean free interval was 39 ± 27 h. 12 cases (24%) had single fractures and 38 (76%) multiple fractures. Forty-four patients had a fractured femur. Thirty-two patients presented the complete clinical syndrome with general, respiratory, neurological and cutaneous signs. Thrombocytopaenia and hypocholesterolaemia were the biological signs most often seen. In forty-four patients, orthopaedic treatment consisted of immediate immobilization, usually with traction. Twenty-six patients were reoperated on : intramedullary nail for twenty patients, plate for the other six. Fat embolism appeared in spite of surgery in six cases; it worsened after surgery in six others. Seven patients had per- or postanaesthetic problems. Fourteen per cent of patients died. The decrease in mortality was mainly due to an improvement in mechanical ventilation techniques. Early surgical fixation remained the rule if there was no serious respiratory distress or haemodynamic instability, although it did not seem to change the mortality rate in this group of patients.
