Medical & Surgical Asepsis

🧼 Medical & Surgical Asepsis

Asepsis means the absence of disease-causing microorganisms. In nursing, aseptic techniques prevent infection by breaking the chain of transmission.

1️⃣ Medical Asepsis (Clean Technique)

• Goal: Reduce the number and spread of microbes; prevent cross-infection.
• Features: Routine care; clean (not sterile); hand hygiene, cleaning, disinfection, PPE as indicated.
• Examples: Handwashing before/after patient care; cleaning equipment between patients; wearing gloves for body-fluid exposure.

2️⃣ Surgical Asepsis (Sterile Technique)

• Goal: Eliminate all microorganisms and maintain a sterile field during invasive procedures.
• Features: Sterile gloves, gowns, drapes, instruments; sterile only touches sterile; when in doubt, consider contaminated.
• Examples: OR procedures, sterile wound dressing, urinary catheter or central-line insertion.
