[Choosing of scale for determining the condition severity in patients with acute blood loss]

Inefficiency of therapy for massive blood losses and hemorrhagic shock can be partially explained by inability to identify, as early as possible, the risk groups. The purpose of our case study was to investigate the significance of diagnostic systems in evaluating the condition severity of patients. One hundred and nine male patients (mean age 41.6 +/- 8.1) were examined within the randomized prospective study. Examinations were made at admission and in 24 and 72 hours after injury according to the protocols of condition severity evaluation--APACHE-II, III (Acute physiology and chronic health condition) and SAPS (Simplified Acute Physiology Score). The scales used in the study are described by a high reliability degree in differentiating the severity conditions of patients (p < 0.0001). The direct linear relation was observed in all cases between the severity condition of patients and the lethality rate (correlation factor r(X,Y) > 0.89). The highest specificity was noted for the APACHE-III diagnostic system.
