An increasing number of reports indicate the efficacy of simulation training in anesthesiology resident education. Simulation education helps learners to acquire clinical skills in a safe learning environment without putting real patients at risk. This useful tool allows anesthesiology residents to obtain medical knowledge and both technical and non-technical skills. For faculty members, simulation-based settings provide the valuable opportunity to evaluate residents' performance in scenarios including airway management and regional, cardiac, and obstetric anesthesiology. However, it is still unclear what types of simulators should be used or how to incorporate simulation education effectively into education curriculums. Whether simulation training improves patient outcomes has not been fully determined. The goal of this review is to provide an overview of the status of simulation in anesthesiology resident education, encourage more anesthesiologists to get involved in simulation education to propagate its influence, and stimulate future research directed toward improving resident education and patient outcomes.

Remimazolam is a recently approved benzodiazepine sedative. We report a case of a 72-year-old man who experienced a cardiac arrest due to severe anaphylaxis immediately after general anesthesia induction. Based on the results of skin tests, including those for dextran 40, an excipient in the remimazolam solution, and a review of drugs given during 3 anesthetics, remimazolam was identified as the probable causative agent. Although remimazolam is structurally similar to midazolam, the patient was not allergic to midazolam as demonstrated before and after anaphylaxis. This report highlights the potential risk of allergic reactions to remimazolam.

No successful resuscitation has ever been reported about intraoperative cardiopulmonary resuscitation (CPR) for an extended period of time in the lateral position. Here we report a case of successful resuscitation without any neurological complication after cardiac arrest due to massive hemorrhage and 25 min of CPR in the lateral position.The patient was a 65-year-old man. During open hemostasis for the postoperative hemorrhage, the patient’s rhythm changed sinus to ventricular fibrillation (VF), followed by asystole. We started CPR immediately with the patient in the left lateral position. Chest compression was performed by two practitioners, one pressing patient’s sternum and the other pressing simultaneously patient’s mid-thoracic spine from his back. During CPR, though the value of end-tidal CO2 (EtCO2) was significantly low (around 5–20 mmHg), the value of systolic arterial pressure was kept about 35–50 mmHg, and diastolic pressure about 20–30 mmHg. After the 25 min of lateral CPR, he achieved the return of spontaneous circulation (ROSC). He was hemodynamically stable after ROSC. He regained his consciousness at the next postoperative day. He was discharged from our hospital on the 60th day of operation without any cardiac and neurological complication.Successful neurological outcome suggests that we may expect satisfactory neurological outcome even in the case of lateral position and prolonged CPR if we perform effective CPR with the feedback of arterial blood pressure and EtCO2 and with the immediate intervention to culprit injuries.
