[Anesthetic Management of a 105-year-old Man Undergoing Emergency Abdominal Surgery].

As Japan's population ages, the number of cases of emergency abdominal surgery at advanced ages is increasing. A 105-year-old man weighing 37 kg combined with aortic stenosis and regurgitation was scheduled for emergency surgery for incarcerated inguinofemoral hernia. General anesthesia was induced with short-acting analgesics and sedatives. The patient was extubated uneventfully in the operating room and discharged without any major complications. Anesthetic management of elderly patients requires appropriate preoperative evaluation of complicating diseases, degree of consciousness, and nutritional condition. For those aged 100 years and older in particular, their quality of life should be considered. Close and cooperative communication between surgeons and anesthesiologists are also an important aspect in treating these charged without any major complications.
