: 333 The safety of anesthesia is also of more concern among patients with OI,: 333  with anesthetic complications 5.6x more likely to occur when the patient has OI type III. A unique concern of anesthesia in OI is perioperative fracture—fractures sustained due to patient transfer and airway access techniques that, while routine when a patients bones are strong, may cause injury with brittle OI bones. As an example, due to a 1972 report of a humerus fracture from a sphygmomanometer cuff sustained in an OI patient during surgery, blood pressure monitoring protocols are often modified for patients with OI, with neonatal size cuffs and machine settings being used even in adults;: ¶11.72  further, the least deformed of the patients limbs is preferred to receive the cuff. : ¶14.23

Rodding
Metal rods can be surgically inserted in the long bones to improve strength, a procedure developed by Harold A. Sofield when he was Chief of Staff at Chicagos Shriners Hospitals for Children, a hospital that offers orthopedic care and surgery to children regardless of their familys ability to pay. Large numbers of children with OI came to Shriners, and Sofield experimented with various methods to strengthen their bones. In 1959, with Edward A. Millar [sic], Sofield wrote a seminal article describing a three-part surgery that seemed radical at the time: precisely breaking the bones ("fragmentation"), putting the resulting bone fragments in a straight line ("realignment"), then placing metal rods into the intramedullary canals of the long bones to stabilize and strengthen them ("rod fixation").
Amlodipine/benazepril, sold under the brand name Lotrel among others, is a medication used to treat high blood pressure. It is a combination of amlodipine, a calcium channel blocker and benazepril, an angiotensin converting enzyme inhibitor. It may be used if a single agent is not sufficient. It is taken by mouth.Common side effects include cough, dizziness, and swelling. Serious side effects may include angioedema, myocardial infarction, high blood potassium, liver problems, and low blood pressure. Use in pregnancy is not recommended. Amlodipine works by increasing the size of arteries while benazepril works by decreasing renin-angiotensin-aldosterone system activity.The combination was approved for medical use in the United States in 1995. It is available as a generic medication. In 2019, it was the 213th most commonly prescribed medication in the United States, with more than 2 million prescriptions. Medical uses
It is used to treat high blood pressure. It is not a first line treatment. References
