- 2. Objectives: After 15-30 minutes of lecture, the students will be able to: 1. differentiate medical from surgical asepsis, 2. identify the different purpose of aseptic technique, 3. enumerate at least 5 indications for aseptic technique, and 4. enumerate the 13 principles of aseptic technique.
- 4. Asepsis • It is the absence of germs or microorganisms.
- 5. Types of Asepsis Medical Asepsis vs Surgical Asepsis
- 6. Comparison Medical Asepsis Surgical Asepsis Reduce the number and spread of microorganisms Destroys ALL microorganisms and their spores Clean technique Sterile technique Ex. Hand washing, Wearing hospital garments Ex. Gas sterilization, autoclaving
- 7. Aseptic Technique • Used to help prevent or minimize contamination of wounds and other susceptible sites by organisms that could cause infection. • Known as ‘Surgical asepsis’ • Is employed during any procedure that bypasses the body’s natural defenses.
- 8. Aim of aseptic technique • To protect the patient from infection and to prevent the spread of pathogens
- 9. Indications for the use of aseptic technique • Suturing and care of surgical wounds • Insertion of invasive devices, such as peripheral and central venous catheters (CVC) • Insertion of urethral catheters and tracheostomy tubes

Editor's Notes
- Brief introduction In 2003 DOH published ‘Winning Ways’ a strategy for reducing healthcare associated infections. Goal health care providers to consistently perform high standards of aseptic technique become a requirement for all health organisations to have a standardised technique for asepsis
- The fundamental principle of asepsis is to prevent infection. Methods of asepsis/ sterility Chemical –gas sterilization physical methods- autoclave
- for example the skin, mucous membranes or when handling invasive equipment such as intravenous cannulae and urinary catheters. In 2003, the Department of Health published ‘Winning Ways’ a strategy for reducing healthcare associated infections. It stated that “Clinical teams will demonstrate consistently high standards of aseptic technique …” It is now a requirement for all NHS organisations to have a standardised technique for asepsis, and compliance should be audited.
- The Center for Disease Control and Prevention (CDC) estimates that over 27 million surgical procedures are perdomred each year in the US. Surgical site infection rannked as the third most common nosocomial infection and are responsible for longer hospital stays and increased costs to the patient and the hospital. Aseptic technique is vital in reducing the morbidity and moratlity associated with surgical infections.
- When preparing for the equipments that are to be used for an operation, always remember that the equipments are already sterilized and therefore are free from pathogen so never touch them with your bare hands.
- Sterile persons only include: Doctor, Assistant, Instrument Nurse, Suture Nurse Unsterile person include: Anesthesiologist, Circulating Nurse
- Ex. If you needed to use HCL and you have seen it already has a different color, remember that hydrochloric acid should always be colorless so if you have seen it otherwise then you should doubt its sterility and consider it unsterile. Another example would be if an HCL bottle does not have an expiry date, then doubt its sterility and consider it unsterile.
- When opening your gown always remember to keep at least a meter away from the table because when your gown accidentally touches below the table surface level then your gown would become unsterile.
- Sterile Part: From Chest to Waist, Sleeve that covers the Hands to 1 inch beyond the elbow of sleeves Unsterile Part: Back, Shoulders to 1 inch before the elbow of sleeves, Waist and below
- Never touch the rim of bottles/containers of sterile content. Consider the rim of bottles unsterile. Never touch equipments on rims of bottles. Before using the sterile content, pour a little amount to clean the rim of its container.
- Although sterile persons are sterile still refrain from touching the sterile equipments to prevent any contamination.
- Sweat is moisture and may cause contamination. Your armpit is one site so never place your hands under it or near it.
- Your sterile gloves' pack should never be folded to prevent crease and to prevent it from easily being torn and exposed. Sterile packages or fields are opened or created as close as possible to the time of actual use. Non-sterile items should not cross above a sterile field. Contaminated items must be removed immediately from the sterile field. There should be no talking, laughing, coughing or sneezing across a sterile field. Personnel with colds should avoid working while ill or apply a double mask. A safe space or margin of safety is maintained between sterile and non-sterile objects and areas.
