Anaesthesia
-
We conducted a postal survey of all consultant-led UK obstetric anaesthetic units in August 2009, to assess the standard of aseptic technique used for neuraxial blocks. One hundred and sixty-four units responded giving a response rate of 76%; 93% of units (149/160) follow recommended precautions and attach a bacterial micropore filter to the epidural catheter. ⋯ If required to draw opioid from a non-sterile-wrapped ampoule, 86% (119/138) of units use a micropore filter and 21% (29/138) wipe the ampoule neck with an alcohol swab. Although sepsis secondary to neuraxial block in obstetric practice is uncommon (declared by 8.5% of units over an unspecified period of time), there is scope for further improvement.
