Development and validation of a predictive risk factor model for epidural re-siting in women undergoing labour epidural analgesia: A retrospective cohort study

Epidural catheter re-siting in parturients receiving labour epidural analgesia is distressing to the parturient and places them at increased complications from a repeat procedure. The aim of this study was to develop and validate a clinical risk factor model to predict the incidence of epidural catheter re-siting in labour analgesia.
