title: [Comparative circulatory studies during implantation of total endoprostheses using methylmethacrylate and BDF cement].
abstract: In every ten patients undergoing elective surgery for total hip prosthesis methylmethacrylate and BDF cement respectively were used for the implantation of the prosthesis. The results of the haemodynamic investigation demonstrate that improvement of the surgical procedure may reduce the incidence of haemodynamic parameters: After implantation of methylmethacrylate into the femoral shaft the arterial pressure decreased from 95.9 +/- 13 to 86 +/- 11 torr (P less than 0.05); the left ventricular stroke work index dropped from 49.9 +/- 5 to 42.1 +/- 7 g.m/m2 (P less than 0.01). While total peripheral resistance decreased slightly in the methylmethacrylate group, there was a small increase after implantation of BDF cement into the femoral shaft. In both groups, however we found a slight elevation of pulmonary vascular resistance after cement implantation into the femur. The determination of the serum concentration of the cement monomer did not yield any measurable serum concentrations. Heat production by polymerisation of BDF cement (maximum 45.8 +/- 6.5 Centigrade) was much less compared with the temperature which developed during the polymerisation of methylmethacrylate (maximum 63 +/- 16.4 Centigrade); therefore, the safety of clinical application seems to be greater with the new BDF cement.
