4.1.01. General Principles of Perioperative Antibiotic Profylaxis

Surgical antibiotic prophylaxis is not just a pre-operative task—it is the initiation of a meticulously managed physiological state designed to protect patients when they are most vulnerable. This video provides a complete, evidence-based framework for mastering surgical prophylaxis, from foundational concepts to complex clinical execution. We break down the three core principles—Timing, Duration, and Selection—and explain why modern evidence overwhelmingly supports a single dose (or 24 hours) over historical multi-day regimens. Through didactic case studies, we'll show you how to apply these principles to challenging scenarios involving obesity, MRSA, penicillin allergies, and the critical need for intraoperative redosing. Finally, we explore the central tension between antimicrobial stewardship and clinical risk aversion that defines modern practice.
