Anaphylactic shock is a potentially lethal complication during anesthesia and requires appropriate management to save the patient's life. We report a 32-year-old man who developed anaphylaxis during induction of general anesthesia with remimazolam for hand surgery. He received general anesthesia with midazolam 4 weeks before. ⋯ Despite no increase of serum tryptase levels, intradermal allergy tests 4 weeks postoperatively revealed that remimazolam and midazolam were positive, suggesting remimazolam as a causative agent for anaphylaxis. In the previous surgery, midazolam, which has a similar structure to remimazolam, may have caused sensitization. This is probably the first case report of anaphylaxis caused by remimazolam.

Randomized Controlled TrialAccuro ultrasound-based system with computer-aided image interpretation compared to traditional palpation technique for neuraxial anesthesia placement in obese parturients undergoing cesarean delivery: a randomized controlled trial.
Recently, a new handheld ultrasound-based device, called Accuro, has been commercialized with a real-time automated interpretation of lumbar ultrasound images. We hypothesized that the handheld ultrasound device would improve the efficacy and safety of combined spinal-epidural anesthesia (CSEA) for cesarean delivery in obese parturients. ⋯ Our study suggests using the Accuro ultrasound device can enhance the efficacy and safety of CSEA in obese parturients when executed by experienced anesthesiologists, and its automated estimation of epidural depth is accurate.

Randomized Controlled TrialComparison between the effects of normal saline with and without heparin for the prevention and management of arterial catheter occlusion: a triple-blinded randomized trial.
We aimed to compare the effects of saline with and without heparin on the catheter-occlusion rate and coagulation-related blood test results for the management of arterial catheters among patients admitted to a short-term intensive care unit postoperatively. ⋯ Normal saline with and without heparin showed similar efficiency for both the prevention of occlusion and the results of coagulation.
