ABSTRACT
BACKGROUND: We present a case of inadequate spinal anesthesia possibly due to cerebrospinal fluid (CSF) leakage into the epidural space caused by accidental dural puncture (ADP). CASE PRESENTATION: A 28-year-old woman with twin pregnancy underwent a cesarean section. She was scheduled to undergo combined spinal-epidural anesthesia (CSEA). Hyperbaric bupivacaine 9 mg with fentanyl 15 µg, with an additional bupivacaine 5 mg was administered from the L3/4 interspace for spinal anesthesia after repeated ADP at T12/L1; however, analgesia level was only up to T12. Insufficient analgesia level would be attributed to leakage of bupivacaine into the epidural space with the CSF via the injured dura. Planned surgery was performed under general anesthesia and completed uneventfully. CONCLUSION: In spinal anesthesia performed after ADP in pregnant women, the anesthesia level may not increase as expected if there is a large amount of CSF leakage.
