Abstract:
A 47-year-old woman with postdural puncture headache suffered from transient paralysis and paresthesia immediately after the epidural blood patch. After one and a half hour, these symptoms disappeared spontaneously. We suspect that the spinal cord or spinal nerve root was transiently pressed by the viscous blood mass, because blood sampling maneuver took a few minutes. With passing of time, the viscous blood spread through the epidural space, and neurological symptoms improved. Although the risks of epidural blood patch are relatively low, we should closely pay attention to unexpected side effects.

Local Anesthetics: Clinical Application as Epidural Anesthesia
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
