Introduction:

The approach to the subarachnoid space was described by Quincke in 1891. It is now a common practice to perform subarachnoid neuroaxial anesthesia in obstetric patients. The complications described, associated with this, are several. Within these, the paralysis of the abducens nerve or sixth pair is not frequent and sometimes is not related to the puncture, since it occurs days after the event.

Objective:

To review the information related to the complication of paralysis of the sixth pair.

Case presentation:

A 33-year-old female patient, a physician, with a personal history of migraine, a history of epidural neuroaxial anesthesia without complications, who underwent combined epidural-spinal anesthesia for performing a cranial segment cesarean section and bilateral partial salpingectomy. The transoperative period runs with hemodynamic stability. There was headache three days after surgery, which was attributed to the migraine history and the patient was treated, without evaluation by anesthesiology, with dipyrone. At 10 days after surgery, the eyes are diverted and diplopia is manifested, paralysis of the sixth pair is diagnosed. She was treated by neurology and several differential diagnoses were proposed. Imaging studies are negative. She was treated with vitamins and remission occurred at six weeks.

Conclusions:

The diagnosis of this complication is necessary, since the relationship with anesthesia may go unnoticed and, therefore, its treatment may be poorly conducted.
