Complications of Epidural Anesthesia in Obstetrics
It would be impossible for me to review even superficially the world literature on this subject within the time allotted for this paper. I intend, therefore, to refer only to our own experience, which is of more than 19,000 epidurals given in an Obstetric Unit. All of these have been continuous lumbar epidurals — none has been a single shot. All injections have been made through a bacterial filter. The test dose has always been 2 ml lignocaine plain (0.5% or 1.0%). Except for brief studies with procaine and etidocaine, the local anaesthetic has invariably been bupivacaine (0.25% or 0.5%, and occasionally 0.375%) and since 1973 it has always been the plain solution.
