Evaluation of autologous shed blood for autotransfusion after orthopaedic surgery.

Autologous shed blood for autotransfusion was evaluated at four medical centers in a prospective randomized study. One hundred twenty-eight patients were studied after hip replacement, knee replacement, or spine fusion. The efficacy of autologous shed blood in reducing homologous transfusion was evaluated.

A prospective, controlled study of a 9/0 elastic polypropylene suture for cataract surgery: refractive results and complications.

A prospective, randomised study was performed on 52 patients undergoing routine limbal extracapsular cataract surgery to compare the effect of 10/0 nylon and 9/0 elastic polypropylene sutures on post-operative astigmatism. Both the magnitude and the axis of the astigmatism were measured by keratometry and refraction pre-operatively and at regular intervals for 3 months post-operatively. Both groups showed an increase in the magnitude of astigmatism immediately post-operatively.

Methylmethacrylate monomer and fat content in shed blood after total joint arthroplasty.

Twenty-five patients were prospectively evaluated to quantify levels of methylmethacrylate monomer and fat in systemic blood and in shed blood after total joint arthroplasty. Levels of methylmethacrylate monomer in systemic blood were measured at intervals after insertion of the prosthesis. Levels of methylmethacrylate monomer in shed blood were measured at intervals after insertion of the drain.
