Case Reports
[Administration of sugammadex to a patient with myasthenia gravis with fade of the train-of-four ratio].
A 50-year-old man (weight 87 kg, height 171 cm) with myasthenia gravis (MG) was scheduled for extended thymectomy under general anesthesia. His preanesthetic train-of-four ratio (T4/T1) was 59%. The first twitch of the train-of-four (T1) was 130% after calibration. ⋯ After 5 min, T4/T1 had reached 54%, but T1 had not reached the control value; therefore, we administered additional 1.5 m x kg(-1) of sugammadex. Subsequently, T1 reached 120%. Patients with MG with fade on T4/T1 require a full dose of sugammadex, identical to the dose administered to normal patients.

The effect of interscalene block on postoperative pain after arthroscopic rotator cuff reconstruction (ARCR) was evaluated. ⋯ Single-shot interscalene block with less than 10 ml of ropivacaine before ARCR reduced postoperative pain only for several hours after the operation.

We experienced pheochromocytoma resection and coronary artery bypass grafting under cardiopulmonary bypass (CPB). The patient was a 69-year-old man who was first diagnosed with atherosclerotic angina. During operation, his blood pressure increased at induction and manipulation of the tumor under CPB, associated with an increased serum noradrenaline concentration. ⋯ Surgical and hemodynamic management was facilitated by TEE. TEE was useful to make a diagnosis of cardiac pheochromocytoma, to determine the area of resection, to determine the surgical repair, and to make a decision of hemodynamic management in this complicated patient. We suggest that perfoming these cases under CPB and TEE is recommended for stabilization of hemodynamic states.

The ability to assess pain intensity is essential for both clinical trials and effective cancer pain management, although cancer pain assessment is complicated by a number of other bodily and mental symptoms such as fatigue and depression, all affecting quality of life. Several pain assessment tools have been shown to be reliable and reasonably valid in assessing cancer pain. ⋯ A variety of scales use drawings of faces (from smiling to distressed) for children or patients with cognitive impairment or dementia. The healthcare providers should use tools valid for the patient's age and cognitive abilities, with additional attention to the language needs of the patient.

Randomized Controlled Trial
[Usefulness of Epidrum for teaching identification of the epidural space].
Epidrum (ED) is a device to facilitate the epidural anesthesia procedure. Using ED, we can visually confirm the needle's penetration into the epidural space by collapse of the diaphragm. We investigated the usefulness of ED for teaching identification of the epidural space. ⋯ The results suggest that ED is a useful device for teaching identification of the epidural space.
