Abstract:

BACKGROUND: Clinical effects of tranexamic acid plus drain-clamping to reduce blood loss in total knee arthroplasty still remain uncertain.

OBJECTIVE: To systematically review the clinical effects of tranexamic acid plus drain-clamping to reduce blood loss in total knee arthroplasty.
METHODS: PubMed, EMBASE, The Cochrane Library, CNKI, VIP and WanFang databases were searched for the clinical trials addressing tranexamic acid plus drain-clamping versus other methods in total knee arthroplasty from January 2008 to June 2018. Two authors independently screened the literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality. The primary measurement outcome was the number of patients with blood transfusion. The secondary outcomes were total blood loss, drainage volume, decrease in hemoglobin, and the incidence of deep venous thrombosis. Changes in these outcomes were analyzed by a meta-analysis on RevMan 5.3 software.
RESULTS AND CONCLUSION: (1) Twelve studies with 1 220 patients were included. (2) Meta-analysis results showed that the number of patients with blood transfusion in the trial group was significantly less than that in the control group [RR=0.35, 95%CI (0.23, 0.52), Z=5.22, P < 0.05]. (3) The total blood loss [MD=-325.45, 95%CI (-445.12, -205.78), Z=5.33, P < 0.05], drainage volume [MD=-269.85, 95%CI (-334.78, -204.93), Z=8.15, P < 0.05], and the decrease in hemoglobin [MD=-0.91, 95%CI (-1.23, -0.58), Z=5.46, P < 0.05] in the trial group were significantly lower than those in the control group. The incidence of deep venous thrombosis in the trial group was slightly lower than that in the control group [RR=0.40, 95%CI (0.08, 2.05), Z=1.09, P > 0.05]. (4) These results show that compared with the control group, tranexamic acid plus drain-clamping can significantly reduce perioperative blood loss in total knee arthroplasty. The number and the quality of the included studies are far from perfect, so more high-quality randomized controlled trials are needed to identify the optimal dose of tranexamic acid and the clamping hours.
