AbstractA review of complications related to epidural catheters in caesarean delivery is presented. Catheters for prolongation of nerve blocks were first used in 1940s. Thereafter, there has been steady development in the design and plastic material technology of the different catheters. In the last decade the regional anaesthesia for caesarean section became very popular, as well as continuous increase in the use of epidural catheters. The anatomical changes of pregnancy like marked distension of the epidural veins resulted in increased risk of the complications due to the epidural catheter placement. It is likely that permanent neurologic sequelae due to regional anaesthesia in obstetrics almost never occur, while minor self-limiting complications do occur. The possible complications of epidural catheter techniques are: trauma, malposition and migration of the catheter, knotting and breaking, radiculopathy, dural puncture, subdural injection, abscess and infection, haematoma and wrong solution injection. Most of the malpositions of the epidural catheter can be avoided by a careful technique, advancing the catheter with no forceful movement and not more than 3 to 4 cm into epidural space. Broken parts of the catheters should be left as a rule within the spinal space. Test dose should be always done for continuous epidural anaesthesia. Early diagnosis and prompt appropriate treatment will usually lead to complete resolution of the neurological deficit even in cases of epidural haematoma or abscess.
