Continuous in situ diffusion of ropivacaine for ambulatory congenital hand disorders surgery in young children

Pediatric ambulatory surgery presents a specific set of challenges to the anesthesiologist. Similarly to adult ambulatory surgery, we report four ambulatory surgical procedures in two young children with congenital hand disorders. For each surgical procedure pain was controlled with continuous in situ infusion of ropivacaine.

[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.
