It will provide the students with a knowledge that he/she will be able to apply when working in the surgical arena. He/she will be better able to understand the concepts of sterile technique and its effects on the surgical patients with respect to prevention of infection. Desired Outcome The learner will be able to correlate the impact of microbiology in providing quality, nonthreatening care to the surgical patient. Performance Objectives 1. 2. 3. 4. 5. 6. 7. 8. Correlate the impact of microbiology in relationship to the practice of sterile technique and infection control in the operative setting. Contrast and compare the structures and characteristics of different microorganisms Analyze the various immune responses that occur in the body as defenses against invasion of pathogens Relate the infectious process to surgical practice Distinguish the difference between intentional, unintentional and incidental/chronic wounds Analyze the mechanism of wound healing, the inflammatory process and the healing process Evaluate the classifications of surgical wounds, analyze factors that influence healing, and devise a plan to prevent postoperative wound infections. Demonstrate basic wound care concepts and apply the principles of asepsis to the practice of sterile technique. Content Outline MICROBIOLOGY I. Introduction to microbiology A.
