Abstract
Epidural block is an appropriate anesthesia method for outpatient operation. This technique is generally safe and efficient. We present the case of a 20-year-old female patient with accidental subdural block after a single dose of epidural block for pilonidal sinus surgery. Sudden apnea, unconsciousness, and bilateral mydriasis occurred within a few minutes after injection. Within 80 minutes after injection, the patient regained full consciousness and spontaneous respiration, with motor block in lower extremities and sensory block until the T4 level. Motor block continued until 165 minutes after injection, whereas sensory block ended 225 minutes later.
