Effects of combined dexamethasone and tranexamic acid in lower limb total arthroplasty: a systematic review and meta-analysis of randomized clinical trials.

Purpose: To evaluate the effectiveness of combined Tranexamic acid (TXA) and dexamethasone (DEX) in total hip and knee arthroplasty.

Methods: PUBMED, EMBASE, MEDLINE and CENTRAL database were systematically searched for randomized studies that utilized TXA and DEX administration of TXA in THA or TKA.

Results: A total of three randomized studies enrolling 288 patients were eligible for qualitative and quantitative analysis. DEX + TXA group demonstrated statistical significantly lesser usage of oxycodone (OR: 0.34, p < 0.0001), metoclopramide (OR: 0.21, p < 0.00001), lesser incidence of postoperative nausea and vomiting (OR: 0.27, p < 0.0001), better postoperative range of motion (MD: 2.30, p < 0.00001) and shorter length of hospital stay (MD: 0.31, p = 0.03). Comparable results were seen in total blood loss, transfusion rate and postoperative complications.

Conclusion: In this meta-analysis, the combination of TXA and DEX has positive impacts on the usage of oxycodone and metoclopramide, postoperative range of motion, postoperative nausea and vomiting and reduces the length of hospital stay.
