MESS (Mangled Extremity Severity Score) is a simple rating scale for lower extremity trauma, based on skeletal/soft-tissue damage, limb ischemia, shock, and age. Retrospective analysis of severe lower extremity injuries in 25 trauma victims demonstrated a significant difference between MESS values for 17 limbs ultimately salvaged (mean, 4.88 +/- 0.27) and nine requiring amputation (mean, 9.11 +/- 0.51) (p less than 0.01). ⋯ In both the retrospective survey and the prospective trial, a MESS value greater than or equal to 7 predicted amputation with 100% accuracy. MESS may be useful in selecting trauma victims whose irretrievably injured lower extremities warrant primary amputation.

One regional trauma center's experience with a large number of seriously injured pregnant women was reviewed to identify factors affecting maternal and fetal outcome after injury. Of 318 pregnant women who suffered trauma from January 1984 through December 1988, 25 (8%) were severely injured and would have required hospital admission even in the absence of pregnancy. Physical examination, except for the inappropriate absence of fetal heart tones, was a poor predictor of fetal status. ⋯ Maternal evaluation and treatment should occur in a stepwise and organized fashion following the general principles of trauma care (ATLS guidelines) in conjunction with perinatal specialists. Uterine ultrasonography should be an integral component of the initial evaluation. With expedient resuscitation, evaluation, and intervention, maternal and fetal survival can be expected.

Twenty-eight patients surviving severe chest injury were studied prospectively (Group I) to assess the timing of recovery and the degree of residual pulmonary dysfunction. Pulmonary function tests (PFT) were obtained within 2 weeks of discharge and serially at intervals of 3 to 6 months. In addition, 16 patients injured 1 to 11 years previously (mean, 33 months) were recalled to determine long-term respiratory disability (Group II). ⋯ Long-term respiratory disability was present in less than 5% of patients studied. We conclude that recovery from severe chest injury occurs rapidly in most patients and serious long-term respiratory disability is uncommon. These results justify the commitment of major resources to the intensive care of patients with severe chest injuries.

ASCOT (A Severity Characterization of Trauma) is a physiologic and anatomic characterization of injury severity which combines emergency department admission values of Glasgow Coma Scale, systolic blood pressure, respiratory rate, patient age, and AIS-85 anatomic injury scores in a way that obviates ISS shortcomings. ASCOT values are related to survival probability using the logistic function and regression weights reaffirm the importance of head injury and coma to the prediction of patient outcome. The ability of TRISS and ASCOT to discriminate survivors from non-survivors and the reliability of their predictions, as measured by the Hosmer-Lemeshow statistic, were compared using Major Trauma Outcome Study (MTOS) patient data. ⋯ Statistically reliable predictions were not achieved by TRISS for either set. ASCOT provides a more precise description of patient physiologic status and injury number, location, and severity than TRISS. The ASCOT patient description may be useful in relating to other important outcomes not highly correlated with TRISS or the Injury Severity Score (ISS) such as disability, length of stay, and resources required for treatment.
