Introduction

The aim of this module is to facilitate student learning regarding aseptic technique. It has beenproduced using guidance from the Aseptic Non Touch Technique (ANTT) guidelines designed byThe Association for Safe Aseptic Practice (ASAP) along with The Royal Marsden Hospital Manualof Clinical Nursing Procedures and video and photography from local sources.

Learning Outcomes

At the end of the session the student should be able to:

Describe the principles of ANTT.

Discuss the steps required to prepare the patient and environment when dressing a wound.

Describe the equipment required for carrying out a simple wound dressing.

Define the key aspects of the two types of ANTT and identify when each should be utilised.

Demonstrate in a practical procedure session how to apply the standard principles of ANTT.

Evaluate own knowledge of the principles of ANTT and formulate an action plan tocompensate for any deficits.

Introduction

Thousands of patients every year worldwide suffer harm or die as a direct result of contracting health careassociated infections (HCAI).

Approximately 30% of HCAI’s are likely to have been preventable.

Health care workers themselves are a significant risk factor to the patient when it comes to the transfer of micro-organisms and infection. The level of risk can be minimized by using an effective aseptic technique during anyinvasive procedure or when dealing with any invasive device.

ANTT is a comprehensive practice framework for aseptic technique and is used throughout the UK NHS andwidely internationally. It provides health care workers with logical standardized guidelines to follow whichreduces the variability in practice and supports health care workers to practice safely and efficiently.

Introduction

Most technical dictionaries define asepsis as the ‘absence of micro-organisms’ however, this is not achievable in

typical health care settings. As such the ANTT principle defines Asepsis as:

Free from pathogenic organisms in sufficient numbers to cause infection

This module has been designed to help you understand the concept of asepsis and how to effectively use ANTT inclinical practice.

Introduction

When using ANTT, asepsis is achieved by Key-Part and Key-Site protection. The aim is to protectKey-Parts and Key-Sites from contamination by micro-organisms which can be transferred by thehealth care worker or the immediate environment.

Asepsis can be maintained during any procedure regardless of circumstance or where it iscarried out. The main concept to remember is that all Key-Parts and Key-Sites need to remainprotected at all times.

Introduction

KEY-SITES

Any portal of entry on a patient:

• Open wounds• Surgical incisions• Puncture sites• Insertion sites

Example:

• Area that a needle of an injection breaks the skin

• Opening of urethra during catheter insertion

KEY-PARTS

Critical parts of procedure equipment that come into contact with active Key-Parts connected to the patient, any liquid infusions or Key-Sites:

• Tip of syringe• Needles• Wound side of

dressing• Intravenous port• Catheter

Introduction

There are two kinds of ANTT used in clinical practice. The type of ANTT chosen by the health care worker for each clinical procedure is dependent on the complexity of the procedure and the level of precaution required.

Introduction

STANDARD ANTT

Used for technically uncomplicated invasiveprocedures that involve minimal Key-Parts andsmall Key-Sites, are significantly invasive and areshort in duration (approximately <20 minutes).Some examples are:

• Simple wound dressings

• Reconstituting and administering certainmedication

• Cannulation

• Venepuncture

SURGICAL ANTT

Used for technically complicated invasiveprocedures that involve large or numerous Key-Parts or Key-Sites, significantly invasive or willtake longer than 20 minutes to complete. Someexamples are:

• Surgical wound dressings

• Any procedure involving incisions throughskin

• Placement of central venous lines


ANTT Risk Assessment

NextBack


To determine Standard or Surgical-ANTT consider the risks posed by:

• The procedure environment

• Procedure invasiveness

• The number and size of Key-Parts and Key-Sites

• Operator competency

• Procedure duration

Then ask…

‘To maintain asepsis of Key-Parts and Key-Sites does the main aseptic field need *Critical Management?’

i.e. *only sterilised and aseptic equipmentmay come into contact with the asepticfield).

Surgical-ANTT

Standard-ANTT

Yes

No



The choice of Surgical ANTT is the approach required for a Wound Dressing application or change.


Aseptic field management Glove choice

‘To maintain asepsis of Key-Parts and Key-Sites, does the main aseptic field require Critical Management?’

- General Aseptic Field- Micro Critical Aseptic Fields (MCAF)- Non-touch technique (NTT)- Hand Cleansing- Infective precautions

- Critical Aseptic Field- Critical Aseptic Field Management- Surgical hand scrub- MCAFs & NTT desirable- Infective precautions

‘Can I perform this procedure without touching Key-Parts or Key-Sites directly?’
