Comparing the effects of peripheral nerve block and general anesthesia with general anesthesia alone on postoperative delirium and complications in elderly patients: a retrospective cohort study using a nationwide database.

Introduction: The difference between the effects of peripheral nerve block (PNB) with general anesthesia (GA) and GA alone on the patients' postoperative clinical outcomes remains unknown. We assessed whether there is a difference in postoperative delirium and composite morbidity between patients receiving GA with PNB and GA alone using a national clinical database in Japan.

Methods: We compared the outcomes of patients receiving GA with PNB and GA alone from April 2016 to October 2019.

Skin temperature changes after ultrasound-guided supra-inguinal fascia iliaca block: a prospective observational study.

Purpose: Ultrasound-guided supra-inguinal fascia iliaca block (SFIB) is widely used as regional anesthesia of the hip and thigh. It is difficult to judge the blocking effect and the spreading local anesthesia. We hypothesize that the effect and spread of the block could be proven objectively by a rise in the temperature.

Anesthetic management for a patient with myotonic dystrophy with remimazolam.

Background: Patients with myotonic dystrophy may have increased sensitivity to drugs used for anesthesia. We successfully managed general anesthesia in a patient with myotonic dystrophy using a novel intravenous anesthetic, remimazolam.

Case Presentation: The patient was a 46-year-old man, 169 cm in height, and weighing 60 kg.

Acupuncture for reducing pruritus induced by intrathecal morphine at elective cesarean delivery: a placebo-controlled, randomized, double-blind trial.

Background: Intrathecal morphine is a standard postoperative analgesic administered after cesarean delivery, but frequently causes pruritus. Acupuncture reportedly resolves refractory pruritus in certain patients. The aim of the study was to investigate the effectiveness of acupuncture in preventing pruritus induced by intrathecal morphine.

Acute arterial occlusion due to left ventricular thrombus of Takotsubo cardiomyopathy in a young adult: a case report.

Background: Thromboembolism is a rare complication of Takotsubo cardiomyopathy. Importantly, an acute arterial occlusion needs rapid diagnosis and urgent treatment to help save the patient's life. Here, we report a case of arterial occlusion due to ventricular thrombus of Takotsubo cardiomyopathy.
