Study type
Interventional
Description of intervention(s) / exposure
to evaluate if the reinfusion of cellsalvaged whole blood will impact on coagulation observed in standard laboratory testing and/or thrombelasometry. A minimum of 300ml blood is collected during hip replacement surgery using the SANGVIA cell saver system, filtered and then reinfused immediately post-operatively
