Abstract

|
|
Malposition of catheter in the subdural space is a possible complication during attempted epidural anesthesia. We report here an inadvertent subdural block confirmed by the radiographic contrast material.
Epidural anesthesia was planned for a full-term gravida and epidural catheter was inserted about 3 cm cranially at the level of l1-2 After injection of 19.5 ml local anesthetic, blood pressure was 70/50 mmHg. Fluid was rapidly infused and
intravenous
ephedrine 10 mg was given. After then. Vital signs were well maintained and twin babies were delivered without events. Twentyfive minutes later, she complained chest tightness and became tachypneic. Ketamine 50 mg was given and endotracheal
intubation
was performed with ease. She obeyed command, but could not open her eyes for some duration. Self respiration returned after 110 minutes and minute ventilation was 6 liter/minute at that time. 160 minutes later, extubation was done and
radiological
examination was performed using contrast material. The cathter tip positioned in anterior subdural space at T12 level.
