The woman, whose name was not released, sued the Hospital Virgen de los Lirios in Alcoi after her November stay at the facility, Think Spain reported Tuesday.
The woman said she received surgery for an intestinal problem and while she was recovering, staff unsuccessfully attempted to fit her with a catheter through her main artery. She said the attempt left her with serious nerve damage to her left shoulder.
Hospital staff later realized the procedure was meant for the woman's hospital roommate.
The woman said a nurse came into her room two days later and attempted to give her an enema, which she said seemed "illogical" given that a large part of her intestine had been removed.
The woman refused the procedure and the nurse soon realized the enema was also meant for the roommate.
The patient sued the hospital and was awarded $37,287 in compensation.
