Minimum local analgesic concentration of extradural bupivacaine increases with progression of labour.

abstract：BACKGROUND:Clinicians frequently warn patients of discomfort before potentially painful procedures, despite the lack of evidence that such communications are helpful. We aimed to compare two communications (one with, and the other without, a warning of a 'sting') immediately before i.v. cannulation in order to measure ...
