Anesthesia management in elderly critically ill plateau area patients with severe craniocerebral injury caused by foreign body invasion: a case report 

Background: Anesthesia management in elderly patients with long-term invasive plateau area severe craniocerebral injury is complex, rare, and high-risk. Case: A 76-year-old male had a 26-year history of skull foreign body penetration and 20 days of local pus and pain. His diagnoses included right hypoplasia, a foreign body in the skull with infection, hypokalemia, hypoproteinemia, pulmonary fibrous foci, and bilateral pleural effusion. For almost six months, the patient suffered from recurring headaches, blurred vision, and sluggish movement. The patient had poor diet, and poor sleep quality. The right anterior ear had a 2 cm skin defect with yellow pus and a black metal foreign body tip. The left eyelid was red and swollen, and the left conjunctiva was hyperemic. The right eyelid showed no abnormality with light and adjustment reflexes. Conclusion: To ensure the patient safety, close multidisciplinary collaboration, a precise surgical plan and anesthetic management strategy are essential.
