Aim: To determine the value of peripheral perfusion index (PI) in predicting the prognosis and concurrent organ injuries in multiple trauma (MT) patients.
Materials and Methods: A prospective observational study of 50 patients with MT and 50 healthy volunteers presenting to the emergency department (ED) was conducted. PI measurements were made during the initial evaluation of the patient. PI 1% and below were grouped as low and above 1% as high.
Results: There was statistical significance between the groups in terms of gender, ISS score averages, PI and SI values, and both SBP and IBP (p=0.007, 0.011, <0.001, <0.001, respectively). When the trauma region and admission PI values are compared, there is statistical significance in terms of the presence of pneumothorax, spleen injury, emergent intra-abdominal operation and mortality (p=0.004 and 0.006, respectively). The median spleen injury stage was 2 in the group with high PI while the median stage 4 spleen injury was found in the group with low PI. There is statistical significance between PI values according to survival percentages for the first 24 h, 7 and 30 days (p=0.006). PI was significantly lower in exitus group.
Conclusion: PI was found to be a promising tool to predict the presence of shock, mortality and organ spesific injuries in MT patients early at admission.
