Summary
Total knee and hip arthroplasty for osteoarthritis is performed on still broader indications
even in elderly patients with previous or current medical conditions. Especially comorbidity
like cardiovascular diseases and conditions with increased risk of bleeding or previous
thrombo-embolic events are major challenges.
To facilitate safe use of ropivacaine as an analgesic, information on the concentrations
levels after autologous blood transfusion following local infiltration analgesia is very
crucial. However, very limited data are available. To verify the safety of autologous blood
transfusion, ropivacaine concentrations were studied in 52 patients undergoing either total
knee arthroplasty or total hip arthroplasty.
