Case report of atypical re-sedation after general anesthesia using remimazolam.

Background: Remimazolam, an ultra-short-acting anesthetic with flumazenil as a reversal agent, typically facilitates patient awakening postoperatively. However, our case reveals an unusual occurrence: despite flumazenil initially restoring consciousness, re-sedation due to remimazolam ensued six hours later.

Case: A 65-year-old woman underwent total intravenous general anesthesia with remimazolam and remifentanil during the 140-min surgery.

Smooth Emergence from General Anesthesia after Deep Extubation in a Pediatric Patient Diagnosed with Catecholaminergic Polymorphic Ventricular Tachycardia: A Case Report.

Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a rare genetic disorder where catecholamine causes bidirectional ventricular tachycardia, potentially leading to cardiac arrest. In patients undergoing surgery, sympathetic responses can be triggered in situations associated with surgical stimulations as well as high anxiety before the surgery, anesthetic maneuvers such as endotracheal intubation and extubation, and postoperative pain. Therefore, planning for surgery demands meticulous attention to anesthesia during the perioperative period in order to prevent potentially life-threatening arrhythmias.

Role of magnetic resonance cholangiopancreatography for choledocholithiasis: analysis of patients with negative MRCP.

Objective: To investigate the negative predictive value of magnetic resonance cholangiopancreatography (MRCP) for common bile duct (CBD) stones and the prognosis of patients suspected to have choledocholithiasis in whom the MRCP was negative for CBD stones.

Methods: We enrolled the patients suspected to have choledocholithiasis in whom the MRCP was negative for the CBD stones between January 2008 and March 2011 and retrospectively analyzed the outcomes of 115 patients.

Results: Endoscopic retrograde cholangiopancreatography (ERCP) was performed in 27 patients (23%, group 1), and none had CBD stones.
