difference between medical and surgical asepsis

Key-Parts are the critical parts of the procedure equipment that if contaminated are most likely to cause infection. Open wounds and insertion/puncture sites for invasive medical devices.

Identifying the ‘key parts’ and ‘key sites’ of a procedure and not touching them either directly or indirectly. It defines the infection prevention method and precautions taken during invasive clinical procedures to prevent the transfer of microorganisms from the healthcare worker, procedure equipment or the immediate environment to the patient. Should be used during any procedure that bypasses the body’s natural defences. DefinitionsĪbsence of pathogenic micro-organisms or toxins from the blood or tissues (Wilson, 1995).

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: ANTT refers to Aseptic non – touch technique.
