Trigger point injection treatment is an effective and widely applied treatment for myofascial pain syndrome. The trapezius muscle frequently causes myofascial pain in neck area. We herein report a case in which direct pulsed radiofrequency (RF) treatment was applied to the trapezius muscle. We observed that the RF treatment produced continuous pain relief when the effective duration of trigger point injection was temporary in myofascial pain.

BACKGROUND: The sitting position under general anesthesia is associated with hemodynamic instability. The purpose of this study was to compare the efficacy of a sequential compression device (SCD) with that of elastic stockings (ES) in reducing the incidence of hypotension and other hemodynamic instability in the sitting position during shoulder arthroscopy. METHODS: Fifty-one patients undergoing shoulder arthroscopy were randomly assigned into one of three groups to receive no treatment (control group, n = 17), SCD (SCD group, n = 17) or ES (ES group, n = 17). Hemodynamic variables were measured 5 min after induction of anesthesia (baseline values), and every 1 min from 1 to 5 min after raising the patient to a 70degrees sitting position (T1-5) with the beach-chair. RESULTS: The incidences of hypotension (proportion, 95% CI) were 12/17 (0.71, 0.47-0.87), 5/16 (0.31, 0.14-0.56) and 7/15 (0.47, 0.25-0.70) in the control, SCD and ES group, respectively. The incidence was significantly lower in the SCD group than that in the control group (P = 0.038). At 1 min after sitting position, mean arterial pressure in the control group was significantly lower than that in the SCD group and it was significantly decreased from the baseline value. CONCLUSIONS: SCD could significantly reduce the incidence of hypotension with less hemodynamic instability in the sitting position during shoulder arthroscopy. Although the incidence of hypotension was decreased with the elastic stocking, there was no statistical significance.

Catecholamine-induced cardiomyopathy associated with pheochromocytoma is a relatively well-recognized but rare entity. We report a case of 15-year old man with a pheochromocytoma and severe heart failure caused by a catecholamine-induced cardiomyopathy. He had symptoms such as fatigue, cold sweating, and dyspnea for 7 months. The chest x-ray showed an enlarged cardiac shadow and pulmonary edema. Echocardiography showed severe decreased left ventricular contractility with multiple thrombi and right ventricular hypokinesia with mild pulmonary hypertension. This report describes our experience of the anesthetic management for the removal of pheochromocytoma with catecholamine-induced cardiomyopathy, which barely responded to high vasopressin and epinephrine.
