There is no globally-accepted definition of epidural failure; this leads to wide differences in reported failure rates. A definition of epidural failure was standardised using a modified Delphi approach involving senior obstetric anaesthetists in the UK. Using this definition, epidural failures were calculated in our institution. ⋯ The study identified epidural failure rates using a standardised definition. This information could be used to guide training decisions and to support doctors during their training period.

Assessing blocks after spinal anaesthesia for elective caesarean section: how different questions affect findings from the same stimulus.
A block to touch to T5 is widely used to indicate an adequate level of block for caesarean section with spinal anaesthesia. However, two studies using a "block to light touch" to T5 as their end-point, had a high requirement for intraoperative analgesia and their results cast doubt on the adequacy of a block to touch to T5. On enquiry, these two papers did not assess complete block to touch, but asked mothers when the touch sensation "was the same as" a control stimulus. The difference between these two assessment methods is unknown. The current study presents prospectively collected sensory block data which included both block to touch and the level when touch was the same as a control stimulus. ⋯ When describing a sensory block, not only is it necessary to indicate the exact stimulus used, but it is important to define the actual question asked of the patient. Clinically, block assessment using the first sharp level and touch same as control are equivalent.
