[Fat overload during intake of lipids].

A review of the recent literature indicates that fat overload during the infusion of lipid emulsions remains rare, at least clinically. Nevertheless, two pictures may be seen, the physiopathology of which is discussed:--overload syndrome, with an association essentially of general and digestive signs, related to the accumulation of lipids in a certain number of parenchymatous tissues;--fat embolism. Problem may be seen at any time after administration of the solution is begun. Youth seems to predominate amongst the favourising factors. Prevention is possible if rules of caution concerning dose and the rate of administration are respected, combined with biological surveillance involving at laboratory studies at least once a week.
