Objective To investigate the effect of continuous renal replacement therapy (CRRT) on rhabdomyolysis with acute kidney injury (AKI) following multiple wasp stings. Methods We designed a prospective study which enrolled 132 patients who developed rhabdomyolysis after multiple wasp stings between January 2013 and December 2016 in Jianyang People’s Hospital, West China Hospital of Sichuan University and Anyue People’s Hospital. Among these, 62 patients with AKI were treated with CRRT. The modality of CRRT was continuous veno-venous hemofiltration (CVVH). CVVH was performed for at least 48 hours by using Prismaflex and M100-AN69 hemofilter. Hemofiltration was accomplished using predilution bicarbonate with the replacement fluid rate of 2 000–2 500 mL/h [30–35 mL/(kg·h)]. Heparin or low-molecular-weight heparin was used for anticoagulation, with blood flow rate of 180–200 mL/min. Then intermittent hemodialysis was performed when patients’ condition became stable. Mortality, kidney recovery, biochemical indicators and length of stay were collected. Results Fifty-one patients met the inclusion criteria finally, and four (7.8%) of them died during hospitalization, and the remaining 47 patients survived with completed treatment and follow-up. At 3, 7, and 14 days after treatment, the creatine kinase, myoglobin and lactate dehydrogenase of the patients all decreased significantly and gradually, and returned to normal level finally. Kidney function was recovered in 45 (95.7%) patients within 3 months, and 2 patients suffered chronic kidney disease. The patients’ hemoglobin recovered to normal level at (30.5±11.3) days. Conclusion Rhabdomyolysis and AKI were severe complications following multiple wasp stings, and early CRRT may bring significant benefits to such patients.
