MANAGEMENT OF BLUNT ABDOMINAL INJURIES IN MULTIPLE TRAUMA PATIENTS

The histories of 66 patients with blunt abdominal trauma requiring surgery in the period from 1985 to 1989 were analysed. The patients were divided into three groups on the basis of the other injuries present. Group I, isolated blunt abdominal trauma and blunt abdominal trauma with slight concomitant injuries (18 patients, ISS 17.17+/-1.40); group II, blunt abdominal trauma with severe concomitant injuries but without craniocerebral trauma (23 patients, ISS 29.34+/-1.45), and group III, blunt abdominal trauma with severe concomitant injuries and an additional craniocerebral trauma (25 patients, ISS 31.08+/-1.27, GCS: 10.04+/-0.88). Initially, the diagnosis was made in 23 cases by means of diagnostic peritoneal lavage and in 43 cases by means of sonography. The subsequent laparotomy revealed the ultrasound findings to have been false-positive in 3 cases. No flase-negative ultrasound findings were demonstrated at all. Peritoneal lavage, on the other hand, was found to have yielded false-negative and false-positive findings in 2 cases each. Counting from the time of admission, the time up to diagnosis of the intra-abdominal injury was 85+/-14.3 min in group I, 82+/-9.9 min in group II, and 86+/-12.9 min in group III. Thus, the presence of severe additional injuries did not lead to any significant delay in the diagnosis of blunt abdominal injury requiring surgery. The total mortality rate was 18.18% (group I, 11.1%, group II, 21.7%; group III, 20.0%). Six patients died in the acute phase and a further six patients during their stay on the intensive care ward.
