Convulsion, Loss of Consciousness and Respiratory Arrest during Nerve Block at Neck -Two case reports-

경부에서의 신경차단시 발생한 경련과 의식소실 및 호흡정지 -증례 보고-

Stellate ganglion block and cervical epidural nerve block are frequently practiced in pain clinics because of simple procedure and good effect. Nerve block at head and neck may produce serious complication such as loss of consciousness and cardiac arrest. Blood supply is rich in neck and inadvertent arterial injection of local anesthetics may enter directly into brain. We experienced convulsion and respiratory arrest during SGB and cervical epidural block. The patients were resuscitated successfully and recovered without any adverse effects.
