RESUMEN
Opsoclonus-myoclonus syndrome (OMS) is a very rare neurological disorder thought to be the result of autoimmune responses in the nervous system. The relationship between this disorder and anesthesia procedures has not been studied in detail. To our knowledge, there are only 4 case reports, none of them with epidural-general combined anesthesia. We present a 9-year-old female with OMS due to low-grade neuroblastoma, for 7 years, who underwent tumor remotion due to the large size. Intravenous induction was done with alfentanil, lidocaine, propofol and rocuronium and ropivacaine was administered via lumbar epidural catheter. Adding to the sparse anesthetic management information in OMS, we now show one more possible approach, that can be valuable in high-risk cases, where general anesthesia can be involved with higher risk for the patient.
