[Application of continuous renal replacement therapy in the treatment of myonephropathic metabolic syndrome caused by acute lower extremity ischemia].

ABSTRACT

OBJECTIVE: To summarize the experiences of using continuous renal replacement therapy in the treatment of myonephropathic metabolic syndrome caused by acute lower limb ischemia. METHODS: Retrospective study of patients diagnosed acute lower limb ischemia with surgical treatment between January 2008 and December 2013, among which 22 patients with myonephropathic metabolic syndrome received continuous renal replacement therapy. Summarize the change tendency of myoglobin, urine volume and serum creatinine levels during treatment and analysis the condition changes and prognosis of the patients. RESULTS: Among them, 2 patients were amputated and two died after surgery. The major causes of death were acute renal failure, metabolic acidosis, circulation failure and liver failure, etc. Myoglobin was significantly higher at Day 1 after surgery than that was before surgery (P < 0.05). Urine volume was significantly lower at Day 1 after surgery than that on the day of surgery (P < 0.05). CK was significantly lower at Day 2 after surgery than the day before (P < 0.05). Hemoglobin was significantly lower at Day 1 after surgery than that before surgery (P < 0.05). Serum creatinine levels remained steady. CONCLUSION: In patients of acute lower limb ischemia with myonephropathic metabolic syndrome, early targeted continuous renal replacement therapy may decrease the serum concentrations of myoglobin and CK, improve urine volume, maintain homeostasis, prevent renal function deterioration and improve the prognosis of patients. And it is highly recommended.
