ABSTRACT
BACKGROUND: Reports on the effectiveness of spinal cord stimulation (SCS) for the alleviation of fibromyalgia syndrome (FMS) pain are scarce. We report two cases of effective high-frequency SCS at 1000 Hz against upper- and lower-limb pain in patients with FMS. CASE PRESENTATION: Two women with widespread pain were diagnosed with FMS and the pain gradually worsened. A 1-week SCS trial was conducted in each patient. In both cases, the patients complained of unpleasant sensations during 10-Hz SCS. However, the pain was alleviated after 1000-Hz stimulation without irritation. Therefore, leads and a generator were implanted, after which they felt almost no pain. Moreover, the dose of the oral medication could be reduced and the patients returned to their daily lives. CONCLUSION: SCS at 1000 Hz may effectively treat pain associated with FMS. Therefore, performing an SCS trial for patients with FMS with intractable pain might be worthwhile.
ABSTRACT
RATIONALE: Coffin-Lowry syndrome (CLS) is a rare inherited disease with specific clinical features, such as mental retardation, facial dysmorphism, and cardiac abnormality. In particular, the characteristic facial features of CLS, including retrognathia and large tongue, are associated with difficult ventilation and/or intubation, which is a serious problem of anesthesia management. However, case reports on anesthesia management of CLS are very limited as there are only two published English reports till date. In this case report, we discuss anesthetic and postoperative considerations in patients with CLS, focusing on difficult airway management, and summarize past reports including some Japanese articles. PATIENT CONCERNS: A 25-year-old man with CLS was planning to undergo laminectomy because of progressive quadriplegia caused by calcification of the yellow ligament. We suspected difficulty in airway management because of several factors in his facial features, short thyromental and sternomental distances in computed tomography, severe obesity, and sleep apnea syndrome. DIAGNOSES: Difficult airway was suspected. However, because of mental retardation, awake intubation was considered difficult. INTERVENTIONS: We selected bronchofiberscope-guided nasotracheal intubation, maintaining spontaneous breathing under moderate sedation with a propofol target-controlled infusion. OUTCOMES: Airway management was safely performed during anesthesia induction. LESSONS: In many patients with CLS, difficult intubation was reported, and sedation or slow induction maintaining spontaneous breathing was mainly selected for anesthesia induction. Spontaneous breathing should be maintained during anesthesia induction in case of CLS patients.
