Anesthetic considerations for inadvertent severe hypertension in a patient with osteogenesis imperfecta during the perioperative period.

Osteogenesis imperfecta is a rare genetic syndrome caused by mutations of bone matrix protein type I collagen coding genes, which is characterized by increased bone fragility and recurrent fractures. We report a patient undergoing general anesthesia with additional nerve block for wrist and hip fracture repair. Preoperatively, we were confronted with an inadvertent severe hypertension without significant triggers and history, which prompted us to be vigilant for hypertensive emergencies due to the fragile vessel regulation capacity in osteogenesis imperfecta patients.
