Abstract

Background

We conducted a meta-analysis from randomized controlled trials (RCTs) and non-RCTs to assess the efficacy of aminocaproic acid in cases of primary total hip arthroplasty (THA) or total knee arthroplasty (TKA).

Methods

Potentially relevant academic articles were identified from the Cochrane Library, MEDLINE (1966–2017 October 31), PubMed (1966–2017 October 31), EMBASE (1980–2017 October 31), and ScienceDirect (1985–2017 October 31). Secondary sources were identified from the references of the included literature. The pooled data were analyzed using RevMan 5.1.

Results

Three RCTs and four non-RCTs met the inclusion criteria. There were significant differences in total blood loss (mean difference (MD) = − 495.80, 95% CI − 837.29 to − 154.32, P = 0.004), drainage volume (MD = − 249.43, 95% CI − 286.78 to − 212.08, P < 0.00001), postoperative hemoglobin level (MD = 0.90, 95% CI 0.78 to 1.02, P < 0.00001), hemoglobin reduction (MD = − 0.75, 95% CI − 0.93 to − 0.57, P < 0.00001), transfusion rates (risk difference (RD) = − 0.17, 95% CI − 0.25 to − 0.09, P < 0.0001), average transfusion units (MD = − 0.28, 95% CI − 0.48 to − 0.09, P = 0.004), and length of hospital stay (MD = − 0.33, 95% CI − 0.43 to − 0.24, P < 0.00001) between the two groups. No significant differences were found regarding deep vein thrombosis (DVT) (RD = − 0.00, 95% CI − 0.01 to 0.00, P = 0.36) between the two groups.

Conclusions

The present meta-analysis indicated that the application of aminocaproic acid in THA or TKA decreases the total blood loss, drainage volume, transfusion rate, transfusion units per patient, and length of hospital stay and does not increase the risk of DVT.
