Topical Application of Tranexamic Acid Plus Diluted Epinephrine Reduces Postoperative Hidden Blood Loss in Total Hip Arthroplasty.
We evaluated the efficacy and safety of topical application of tranexamic acid (TXA) plus diluted epinephrine (DEP) and its effect on perioperative hidden blood loss and transfusion requirement in primary unilateral total hip arthroplasty (THA). We randomized 107 patients undergoing THA into two groups: 53 received intra-articular TXA 3 g plus 1:200,000 DEP 0.25 mg; 54 received topical TXA 3 g alone. Results showed that combined administration significantly reduced total blood loss (P=0.009), hidden blood loss (P=0.001) and transfusion rate (1.9 vs. 9.3%) compared with TXA alone, without increasing the risks of thromboembolic and hemodynamic complications. Topical TXA plus DEP in THA can decrease postoperative hidden blood loss and avoid homologous transfusion without substantial complications.

Randomized Controlled Trial
Impact of Melatonin on Sleep and Pain After Total Knee Arthroplasty Under Regional Anesthesia With Sedation: A Double-Blind, Randomized, Placebo-Controlled Pilot Study.
This pilot study explores sleep disruption after total knee arthroplasty and the impact of melatonin on sleep and postoperative pain. Sleep time was decreased on the last preoperative night and first two postoperative nights. ⋯ Melatonin appeared to have no effect on subjective sleep quality or daytime sleepiness, pain at rest or pain with standardized activity. In conclusion, sleep quality is impaired after total knee arthroplasty and exogenous melatonin does not appear to improve postoperative sleep or pain to a significant degree.
