Effects and Safety of Traditional Chinese Medicine for Hidden Blood Loss after Total Hip Arthroplasty-A Systematic Review and Meta-Analysis

Abstract

Background: Hidden blood loss (HBL) after total hip arthroplasty (THA) would lead to many undesirable consequences. Traditional Chinese medicine (TCM) is now increasingly used for hidden blood loss. We performed this systematic review and meta-analysis to summarize the effect and safety of TCM treatment of HBL after THA.

Methods: We searched PubMed, Embase, Cochrane Library, CNKI, VIP, WanFang, and CBM for the updated articles published from the inception of each database to May, 2022, among which results such as abstracts, comments, letters, reviews, and case reports were excluded. The efficacy and safety of TCM treatment of HBL after THA were synthesized and discussed by the outcomes of total blood loss (TBL), hidden blood loss (HBL), hemoglobin (Hb), and hematocrit (HCT), and the incidence of adverse reactions.

Results: A total of 12 articles and 881 patients were included. There were 441 cases in the intervention group and 440 cases in the control group. Compared with the control group, the intervention group had more advantages in TBL (MD = -251.68, 95% CI = [-378.36, -125]; Z = 3.89, P < 0.00001), HBL (MD = -159.64, 95% CI = [-252.56, -66.71]; Z = 3.37, P=0.0008), Hb (MD = 11.39, 95% CI = [7.35, 15.43]; Z = 5.53, P < 0.00001), and HCT (MD = 2.87, 95% CI = [0.97, 4.78]; Z = 2.95, P=0.003), and had less incidence of adverse reactions (OR = -0.20, 95% CI = [-0.35, -0.05]; Z = 2.64, P=0.008).

Conclusion: TCM has advantages in the efficacy and safety of treating hidden blood loss after THA. The strength of the evidence of the research results is limited by the quality of the included literature, and more high-quality RCTs are needed to confirm.
