a) Chlorine (hypochlorites) e.g., Milton, Eusol. Halogens - for inactivation of viruses and anti bacterial activity except TB. 70% - 75% Ethyl or Isopropyl Alcohol - for wide range of antibacterial activity, most active against TB.Ĭhemical Disinfectants cont…. 1% Sudol b) Hexachlorophene e.g., Phisohex, Gamaphene - for wide range of antibacterial activity. Phenolics - a) clear soluble fluids, e.g., 2% Printol. Decontamination of the inanimate environment.Ĭhemical Disinfectants are such as: 1. Disinfection of instruments & other items. Use of Disinfectants Indications for use of Hospital Disinfectants: 1. B) Number of microorganisms present on articles The more heavily contaminated the articles are, the harder for destruction.Įssential factors for maximum effectiveness of disinfection are:- Cleanliness of items - Unlocking all locked instruments - Complete immersion of articles Chemical - disinfectantsĬhoice of method depends on: A) Types of microorganisms Certain strains of bacteria are more resistant to destruction than vegetative forms.

This process can be carried out by two methods: 1.

The principle of disinfection is that of denaturation of the bacterial cell protein.

Sterilization – is the process of eliminating and destroying all microorganisms, including spores & viruses.

Noninfectious microorganisms may or may not be killed. Disinfection – eliminates pathogenic organisms on inanimate objects with the exception of bacterial spore.A brush, detergent or soap are needed for cleaning.These barriers provide protection from infectious organisms.When cleaning equipment that is soiled by organic material such as blood, fecal matter, mucus or pus, the nurse applies a mask, protective eyewear, & waterproof gloves. Reusable objects must be cleansed thoroughly before disinfection & sterilization. Generally, cleansing involves use of water & mechanical action with or without detergents.Is the removal of all foreign materials such as soil & organic material from objects.Effectiveness of aseptic practices depends on the nurse’s conscientiousness & consistency in using effective aseptic techniques.ĬONTROL OR ELIMINATION OF INFECTIOUS AGENTS Cleansing.

A nurse in an operating room follows a series of steps to maintain sterile techniques, including applying a mask, protective eyewear, and a cap performing a surgical hand washing & applying a sterile gown & gloves.

The nurse working with a sterile field or with sterile equipment must understand that the slightest break in technique results in contamination.

In surgical asepsis, an area or object may be considered contaminated if touched by an object that is not sterile (e.g., a tear in a surgical glove during a procedure, a sterile instrument placed on an unsterile surface).

These techniques can be practiced by nurses in the OR (surgical incision) or at the bedside (e.g, inserting IV or urinary catheter & reapplying sterile dressings) where sterile instruments & supplies are used.

Surgical asepsis demands the highest level of aseptic technique & requires that all areas be kept as free as possible of infectious micro-organisms.Sterilizationdestroys all microorganisms & their spores.In medical asepsis, an area or object is considered contaminated only if it is suspected of containing pathogen (e.g., used bedpan, the floor & a wet piece of gauze).Clients with high susceptibility to infection require special precautions to prevent exposure to pathogens.Follow Isolation technique as appropriate.

Eg.of medical asepsis are changing client’s bed linen daily, handwashing, barrier techniques, & routine environmental cleaning.

During daily routine care, the nurse uses basic medical aseptic techniques to break the infection chain.

includes procedures used to eliminate micro-organisms from an area & is practiced by nurses in OTs, labour & delivery area, major diagnostic areas & Rx areas.

Surgicalor Sterile Asepsis or Sterile Technique

Medical or Clean Asepsisreduces the number of organisms & prevents their spread.

There are two types of asepsis: Medical asepsis & Surgical asepsis.

This can be achieved by ensuring that only sterile equipment & fluids are used during invasive medical & nursing procedures.

It is a method used to prevent contamination of wounds & other susceptible sites by organisms that could cause infection.

Aseptic technique is the effort taken to keep the patient as free from hospital micro-organisms as possible (Crow 1989).

Aseptic technique is an effort to keep the client as free from exposure to infection-causing pathogens as possible.

The nurse’s efforts to minimize the onset & spread of infection are based on the principles of aseptic technique.

The term asepsis means the absence of disease-producing microorganisms.
