Safety of blood reinfusion drains after local infiltration analgesia in total joint replacement.

Background: Local infiltration analgesia (LIA) is frequently administered to patient undergoing joint replacement surgical procedures. The aim of the present research was to verify the safety of collected shed blood to be reinfused postoperatively, by measuring levobupivacaine levels in drainage blood in patients undergoing LIA during knee replacement surgery.

Patients And Methods: 24 patients who underwent total knee arthroplasty (TKA) and 12 scheduled for total hip arthroplasty (THA) who received intraoperative LIA were considered.

Nutritional Controlled Preparation and Administration of Different Tomato Purées Indicate Increase of β-Carotene and Lycopene Isoforms, and of Antioxidant Potential in Human Blood Bioavailability: A Pilot Study.

The isoforms of lycopene, carotenoids, and their derivatives including precursors of vitamin A are compounds relevant for preventing chronic degenerative diseases such as cardiovascular diseases and cancer. Tomatoes are a major source of these compounds. However, cooking and successive metabolic processes determine the bioavailability of tomatoes in human nutrition.

Reducing transfusion requirements following total knee arthroplasty: effectiveness of a double infusion of tranexamic acid.

Objective: Blood loss following joint replacement surgery represents a relevant issue for orthopedic surgeons. The use of tranexamic acid (TXA) to reduce transfusion requirements has become mainstream. However, consensus about the starting time, methods, or volume of usage of TXA in joint replacement surgery has yet to be found.
