A 54-year-old woman diagnosed with multiple sclerosis (MS) at the age of 19 years was scheduled to undergo temporomandibular joint mobilization. She was currently in a remission phase from her MS but with persistent sequelae, including impaired eyesight and muscle weakness of the limbs. In addition, the blood vessels in her upper limbs were compromised by the formation of internal shunts secondary to vascular prosthesis replacements for plasma exchange therapy in MS. After a previous joint mobilization surgery, her temporomandibular joint developed adhesions with resultant trismus. One of the adverse effects of general anesthesia can be exacerbations of MS symptoms. Minimizing mental and physical stress caused by surgical and anesthetic procedures and maintenance of stable body temperature are important considerations. Awake intubation was performed under sedation with midazolam and fentanyl. After intubation, anesthesia was induced with propofol, remifentanil, and rocuronium. Maintenance of anesthesia was achieved with oxygen-N 2 O-sevoflurane, remifentanil, fentanyl, and rocuronium. In this case, no adverse events occurred intraoperatively. However, the patient experienced lingering weakness of the limbs in the postoperative period, and activities of daily living of the patient were affected.Key Words: Multiple sclerosis; Demyelinating encephalomyelitis; Trismus.M ultiple sclerosis (MS) is a demyelinating disease of the central nervous system characterized by varying initial symptoms such as visual impairment, bowel/bladder dysfunction, trigeminal neuralgia, cognitive problems, gait disorder, and motor paralysis. We report a case of a patient with MS who underwent temporomandibular joint (TMJ) mobilization under general anesthesia.
CASE REPORTA 54-year-old woman (height, 155 cm; weight, 45 kg) with MS was scheduled for TMJ mobilization under general anesthesia. The patient was diagnosed with MS at the age of 19 years, and reportedly was in remission since the age of 35 years, after multiple episodes of remissions and exacerbations. The MS was treated mainly with steroidpulse, immunoglobulin, and plasma exchange therapy. Although the MS was in a remission phase, she had persisting after-effects, including impaired eyesight due to steroid-induced glaucoma and cataract, and muscle weakness of limbs. She used to walk with the help of a cane, but her activities of daily living had since decreased. In addition, the blood vessels of both upper extremities and the left lower extremity were compromised as a result of formation of internal shunts secondary to vascular prosthesis replacement for plasma exchange therapy and steroid pulse therapy. Her arms and legs appeared edematous. Other medical history included gastroesophageal reflux and history of hypotension. The gastroesophageal reflux was treated with sulpiride (a dopamine antagonist antipsychotic), lansoprazole (a proton pump inhibitor), mosapride citrate (a 5-HT 4 gastroprokinetic), and polaprezinc (a mucosal protective agent), and hypotension was treated with a...
