Interim results of a study conducted by researchers at Hospital for Special Surgery (HSS) suggest that oral tranexamic acid (TXA) is non-inferior to intravenous (IV) TXA in preventing blood loss in total knee and total hip replacement surgery. These findings were presented at the 2021 Spring American Society of Regional Anesthesia and Pain Medicine (ASRA) Annual Meeting.1
Previously available information suggests that oral, IV and topical TXA are all effective at reducing blood loss and drastically reducing blood transfusion rates during and after surgery, but research with direct comparisons for each method is limited. TXA in orthopedic surgery has become the standard of care. However, the most efficient, efficacious and cost effective method of administration remains unknown, said principal investigator Stavros Memtsoudis, MD, PhD, MBA, an anesthesiologist at HSS. The oral administration of TXA is logistically easier, thus reducing the risk of drug errors in the OR.
