Abstract

A prospective study on 227 patients undergoing arthroplasty of the hip was carried out with reference to the effects on the cardiovascular and respiratory systems. Investigations revealed that the placing of acrylic bone cement and the prosthesis in the femoral shaft produced clinical and biochemical disturbances which were consistent with pulmonary microembolism. A fall in arterial oxygen tension during the procedure and hypoxaemia extending into the postoperative period with elevation of serum lipase and a fall in triglycerides supported the idea that embolisation with marrow fat occurred. The method of venting (by catheter or proximal hole) did not influence the biochemical disturbances. The implications of these findings are discussed.
