passages.text: IMPLICATIONS: This case documents a patient who developed dizziness with downbeating nystagmus while receiving a relatively large dose of IV patient-controlled analgesia morphine. Although there have been case reports of epidural morphine with these symptoms and signs, this has not been previously documented with IV or patient-controlled analgesia morphine.
