Preoperative optimization of patients undergoing interventional procedures: infrastructure, logistics, and evidence-based medicine.

PURPOSE OF REVIEW: Patients presenting for non-operating room procedures are often 'too sick' for surgery and require specific anesthesia care in remote areas with logistical and scheduling challenges. RECENT FINDINGS: Increased complexity and scope of minimally invasive procedures have expanded this practice. In addition, the concept of therapeutic options other than conventional surgery is gaining traction. SUMMARY: Our review of recent literature confirms the complexity and supports the safety of providing care in non-operating room anesthesia locations. Standard preanesthesia assessments and principles apply to these areas.
