[Continuous infusion of ropivacaine has no effects on pyrolytic implant: a preliminary study in rats]

The aim of the study is to analyse the effects of ropivacaïne on a pyrolytic implant in bone surgery. Ten rats were operated with a pyrolytic implant placed at the hip after femoral head resection: five cases with continuous infusion of ropivacaïne and five cases with continuous infusion of sterile water. Six days after, all the implants were analysed: weight, length, width, thickness and global design. This work showed that ropivacaïne can be use as continuous infusion with pyrolytic implant. Other studies in human surgery are necessary.
