Abdominal lavage in blunt trauma.

A technique for abdominal lavage is described and was used to evaluate the abdomen of 671 multiple trauma victims. In 44 per cent (299 cases) there was a bloodstained return and these were regarded as positive. Patients with a positive result underwent exploratory laparotomy which revealed that 89 per cent had significant intra-abdominal trauma requiring a surgical procedure, 8 per cent had trauma which did not require any active surgical correction and 3 per cent had no abdnormal findings. Of all the lavages performed, there were 0-11 per cent false positive and 0-03 per cent false negative results. The value of the test in the context of multiple trauma is emphasized.
