[Difficulty of epidural puncture for obstetric analgesia: risk factors].
Predicting technical difficulties in performing an epidural block can affect the anesthesiologist's choice of technique or decisions about who should carry it out. Our aim was to determine patient characteristics associated with difficulty in performing an epidural block for obstetric analgesia. ⋯ The most important factor for predicting success of an epidural block for obstetric analgesia in our practice is the presence of palpable spinal apophyses.
