Perioperative SBP changes during orthopedic surgery in the elderly: clinical implications.

Objectives: We aimed to determine SBP changes during the perioperative period of a scheduled knee surgery under regional anesthesia and the extent of perioperative (in-hospital) white-coat effect.

Methods: All patients (aged ≥60 years) underwent clinic SBP measurements during both cardiological and anesthesiological visits, while home SBP the week before admission was obtained. Clinic SBP was registered just before surgery, during surgery and reanimation.
