Meet the patient
A twenty-six-year-old primigravida is six centimetres dilated, contracting every two minutes, and asking for the epidural she was promised would be instant. The midwife tells you labour has been established for eight hours, the baby is occipito-posterior, and theatre conversion for a slow first stage is genuinely on the table tonight.[1]
The two questions that decide her block are the two that decide every CSE: how fast can I get her comfortable? (the spinal answers within minutes) and how do I keep her covered if this ends in theatre? (the catheter answers that). Hold those two questions and the technique below slots into place.[1]
