- Abstract
Objective: To study the relationship between serum creatine phosphokinase and outcomes of injury in victims with electrical burns., Material and Methods: Among 40 patients with electrical injury, 7 (18%) ones underwent upper limb amputation. There were 37 (92.5%) men and 3 (7.5%) women aged 37 (28; 47) years. We analyzed total serum creatine phosphokinase and MB fraction on the first day in patients with and without amputations., Results: Total serum creatine phosphokinase exceeded the upper reference value in 11 out of 33 patients without amputation and in all 7 patients with limb amputation ( p =0.001). Patients with limb amputation had significantly higher total serum creatine phosphokinase and MB fraction ( p <0.001 and p =0.030, respectively). Logistic regression equation showed that high total serum creatine phosphokinase significantly influenced amputation rate ( p <0.001), as evidenced by odds ratio (42.7, 95% CI 3.5-514.8). ROC analysis revealed the cut-off value of total serum creatine phosphokinase (950 IU/L). Sensitivity was 100% (63; 100), specificity - 94% (86; 94), positive predictive value - 78% (49; 78), negative predictive value - 100% (92; 100)., Conclusion: Total serum creatine phosphokinase depends only on severity of electrical and flame burns. Serum creatine phosphokinase is a predictor of upper limb amputation in patients with electrical injury. Total serum creatine phosphokinase ≥ 950 IU/L is significant for upper limb amputation (in CK-MB fraction within the reference values).
