To evaluate the adjuvant therapeutic effect of Chinese traditional medicine for diabetic ketoacidosis (DKA).Methods:Randomized controlled trials (RCTs) of Chinese traditional medicine adjuvant therapy were retrieved from the Cochrane Library, PubMed, EMBase, Medline,SCI, CNKI, CBM，VIP TCMLARS and AMED databases. We also searched relevant journals by hand. Data were extracted and the quality of literatures were evaluated by two independent reviewers and analyzed by software RevMan 5.2 which provided by the Cochrane Collaboration.Results:A total of 14 studies and 523 patients were included. Meta analysis results showed that in turn ketoacidosis, blood sugar recovery time and acidosis correction time, regular DKA treatment + Chinese medicine group were significantly shorter the conventional DKA treatment group (MD=-9.65,95% CI-12.95～-6.34，P<0.00001；MD=-4.21,95% CI-4.55～-3.87，P<0.00001；MD=-9.95,95% CI-11.07～-8.82，P<0.00001).On response rate, conventional DKA treatment + Chinese medicine group were significantly higher than that of conventional DKA treatment group (RR=1.21,95%CI为1.14～1.27，P<0.00001).Conclusion:Traditional Chinese medicine has good curative effect in adjuvant treatment of diabetic ketoacidosis.
