The aim of this study was to examine the efficacy and safety
of multiple boluses of intravenous (IV) tranexamic acid (TXA) on
the hidden blood loss (HBL) and inflammatory response following
primary total hip arthroplasty (THA). A total of 150 patients were allocated randomly to receive a
single bolus of 20 mg/kg IV TXA before the incision (group A), a
single bolus followed by a second bolus of 1 g IV-TXA three hours
later (group B) or a single bolus followed by two boluses of 1 g
IV-TXA three and six hours later (group C). All patients were treated
using a standard peri-operative enhanced recovery protocol. Primary
outcomes were HBL and the level of haemoglobin (Hb) as well as the
levels of C-reactive protein (CRP) and interleukin-6 (IL-6) as markers
of inflammation. Secondary outcomes included the length of stay
in hospital and the incidence of venous thromboembolism (VTE).Aims
