Infection during chronic epidural catheterization: diagnosis and treatment.

abstract：BACKGROUND:The Atenolol study of 1996 provided evidence that perioperative β-blockade reduced postsurgical mortality. In 1998, the indications for perioperative β-blockade were codified as the Perioperative Cardiac Risk Reduction protocol and implemented at the San Francisco Veterans Affairs Medical Center. The current...
