A survey of how British obstetric anaesthetists test regional anaesthesia before caesarean section.

We surveyed members of the Obstetric Anaesthetists Association asking how they tested regional blocks prior to Caesarean section. A large proportion of these anaesthetists appear to test their blocks inadequately. Temperature sensation was the most common sensory modality tested (64%) and 79% of those who tested for temperature sensation used an ethyl chloride spray.
