Abstract:
Objective To determine the influence factors for limb salvage of bone fracture patients with hyperpotassemia caused by Wenchuan earthquake,to discuss the clinical symptom and to improve the clinical treatment. Methods The clinical symptom, drug therapy, limb incision decompression, hemodialysis, and limb salvage of hyperpotassemia caused by earthquake were analyzed by logistic regression. Results All the 37 patients received drug therapy: 9 patients received incision and decompression singlely,8 received hemodialysis singlely,and the other 20 received decompression and hemodialysis simultaneously. The concentration of potassium decreased from (6.25 ± 0.91) mmol/L to (4.47±0.65) mmol/L,with significant difference (P＜0.05).Five patients with Gustilo III grade open injury received amputation at the concentration of potassium of (6.13±(0.78)) mmol/L, while the concentration of potassium for the other 32 patients was (6.25±0.31) (mmol/L). There was no significant difference between them(P>0.05). Logistic regression analysis found the time of compression, the time before incision and decompression, and the time before hemodialysis were the main factors to affect limb salvage. The OR value of these factors was 4.394, 3.793 and 5.432;while the P value was 0.013, 0.047, and 0.015, respectively. Conclusion Decreasing the time of compression, appropriate incision and decompression, and hemodialysis help improve the result of limb salvage in hyperpotassemia patients with bone fracture caused by earthquake.
