FOUR PRINCIPLES OF ASEPSIS SKIN

The ANTT framework is based upon the goal of asepsis rather than sterility and the approach is gauged on the technical difficulty of each procedure rather than the diagnosis or age of the patient. This standardised approach, developed in University College Hospital (UCH) London, has been shown to significantly improve the aseptic technique of healthcare workers and reduce the numbers of Healthcare Associated Infections (HCAIs).ĪNTT is a core nursing and medical skill that defines the infection prevention and control methods and precautions necessary during invasive clinical procedures to prevent the transfer of microorganisms to ‘key’ or sterile body sites from healthcare professionals, procedure equipment or the immediate environment to a patient. Increase patient safety by reducing the risk of introducing infection into a susceptible body site during procedures such as intravenous therapy, wound care and urinary catheterisation.Īseptic non-touch technique uses a defined framework and is a relatively new approach to undertaking aseptic techniques.Support health care workers to practice safely and effectively.ANTT is an international set of principles aimed to: They should also establish procedures for the safe handling of such equipment during and after use, including cleaning and disinfecting or sterilizing as indicated.ANTT refers to Aseptic non – touch technique. Evaluate equipment and devices for potential cross- contamination of blood.

FOUR PRINCIPLES OF ASEPSIS SKIN

Handle equipment that might be contaminated with blood in a manner that prevents skin and mucous membrane exposures, contamination of clothing, and transfer of microorganisms to themselves, other patients, and surfaces.When dealing with patient care equipment, health care workers should Clean and disinfect blood-contaminated equipment and surfaces in accordance with recommended guidelines.Use barriers to protect surfaces from blood contamination when blood samples are obtained.Prepare medications in areas physically separated from those with potential blood contamination.Maintain physical separation between clean and contaminated equipment and supplies.

Dispose of used syringes and needles at the point of use in a sharps container that is puncture-resistant and leak- proof, and that can be sealed before completely full.

In maintaining a safe and sanitary work environment, health care workers should

Wear gloves for procedures that might involve contact with blood, and change gloves and wash hands between patients.

Wash their hands with soap and water, or use an alcohol-based hand rub before preparing and administering an injection before and after donning gloves for obtaining blood samples after inadvertent blood contamination and between treating patients.

To ensure hand hygiene and proper use of gloves, health care workers should

Use aseptic technique to avoid contamination of sterile injection equipment and medications.

Avoid using bags or bottles of intravenous solution as a common source of supply for multiple patients.

Store vials in accordance with manufacturer’s recommendations and discard if sterility is compromised. Never re-enter a vial with a needle or syringe used on one patient if that vial will be used to withdraw medication for another patient.

Restrict multiple-dose vials (if used) to centralized medication area or use only for a single patient.

Avoid administering medications from single-dose vials to multiple patients or combine leftover contents for later use.

Use single-dose medication vials, prefilled syringes, and ampules when possible.

Use a sterile, single-use, disposable needle and syringe for each injection, and discard them intact in an appropriate sharps container after use.

To ensure injection safety, health care workers should View recommended infection controls and safe infection practices to prevent patient-to-patient transmission of bloodborne pathogens below. All four outbreaks could have been prevented had the basic principles of aseptic techniques for the preparation and administration of parenteral medications been adhered to by health care workers and patients. In 2003, four large outbreaks of HBV and HCV infections occurred in the United States among patients in ambulatory care facilities. The delivery of health care has the potential to transmit HBV and HCV to both health care workers and patients.
