Study Notes
Asepsis and Surgical Asepsis
- Asepsis is the absence of pathogenic microorganisms, crucial for preventing infections.
- Surgical asepsis, also known as sterile technique, maintains an environment free from all microorganisms, particularly during surgical procedures.
Surgical Site Infection (SSI)
- Inadvertent transfer of microorganisms to a wound site during surgery can lead to surgical site infections (SSIs).
- Prevention of SSIs occurs at multiple points in the care pathway, including hand antiseptic cleansing.
Surgical Hand Asepsis
- Essential for nurses in operating rooms to perform hand antisepsis before wearing sterile gowns and gloves.
- Aims to reduce skin microorganism growth in case of glove perforations.
Importance of Aseptic Technique
- An area or object is considered contaminated if it contacts non-sterile items.
- Requires rigorous measures to keep all areas free from infectious microorganisms.
Donning and Doffing PPE
- Donning: Properly putting on PPE to minimize exposure to hazards.
- Doffing: Safely removing PPE to avoid self-contamination.
PPE Assessment and Planning
- Assessment determines the necessary equipment for procedures.
- Planning ensures all steps are taken to maintain PPE integrity and reduce contamination risk.
Gloving Methodology
- Gloving reduces contamination risk between surgeon and patient; done after thorough hand scrubbing.
- Open method of gloving is typically employed in sterile environments.
Oxygen Administration
- Oxygen is vital for cellular metabolism and can be administered through different systems.
- General purposes of oxygen administration include maintaining adequate oxygenation, treating hypoxia, and supporting respiratory functions.
Oxygen Delivery Systems
- Low-Flow Systems: Include types like nasal cannula and face masks, allowing for variable flow rates.
- High-Flow Systems: Provide a fixed flow of oxygen regardless of the patient's breathing pattern.
Specific Considerations for COPD Patients
- Patients with Chronic Obstructive Pulmonary Disease (COPD) require careful monitoring and tailored oxygen therapy to avoid complications such as respiratory failure.
Complications and Safety Precautions
- Potential complications of oxygen therapy include oxygen toxicity, carbon dioxide narcosis, and fire hazards.
- Safety precautions during oxygen administration include avoiding open flames and ensuring equipment integrity.
