[Is a coagulation blood test compulsory before neuraxial blockade for labor analgesia?].

Neuraxial blockade such as epidural, spinal or combined spinal-epidural analgesia is considered to be the best technique for labour analgesia. Even if epidural hematoma is a very rare complication of neuraxial blockade, it may result in severe and definitive neurological injuries. This rare complication is usually associated with coagulation abnormalities. This is the reason why many physicians order routine coagulation screening tests before performing neuraxial blockade. This practice is questionable from the evidence-based medicine and the economic point of view. According to the guidelines published by several scientific societies, no routine coagulation screening tests are required in the absence of any history or clinical suspicion of coagulation impairment. The aim of the present article is to delineate the appropriate attitude in this context.
