Practice medical and surgical asepsis free#

It is also used when performing a sterile procedure at the bedside, such as inserting devices into sterile areas of the body or cavities (e.g., insertion of chest tube, central venous line, or indwelling urinary catheter). Sterile technique is most commonly practised in operating rooms, labour and delivery rooms, and special procedures or diagnostic areas. Principles of sterile technique help control and prevent infection, prevent the transmission of all microorganisms in a given area, and include all techniques that are practised to maintain sterility. In the literature, surgical asepsis and sterile technique are commonly used interchangeably, but they mean different things (Kennedy, 2013).

Sterile technique is a set of specific practices and procedures performed to make equipment and areas free from all microorganisms and to maintain that sterility (BC Centre for Disease Control, 2010). Surgical asepsis is the absence of all microorganisms within any type of invasive procedure.

Cost to the health-care system = $4.1.5 Surgical Asepsis and the Principles of Sterile Technique Surgical AsepsisĪsepsis refers to the absence of infectious material or infection.

Nosocomial Infection An infection acquired in a health-care facility

WBC enter the tissues causing release of pyrogens (fever) exudates form discharge healing occurs.

Cells, proteins, fluids enter the tissue spaces blocking lymphatics to create a ‘wall’ against infection

Tissue dies causing release of chemicals (histamine and prostaglandins) which allow blood vessel permeability.

Aterioles dilate, blood and WBC go to area.

Ex: fever, anorexia, n/v, lymph node swelling.

Affects the entire body and may involve multiple organs, goes through the stages of infection.

Ex: redness, warmth, tenderness, swelling.

Limited to a defined area resembles inflammation.

e.g., Hypertension, diabetes mellitus, osteomyelitis Latent - Infection present with no discernible symptoms.

e.g., Common cold Chronic - Slow development, long duration.

Affects many regions (e.g., septicemia)Ĭlassification of Infections by Duration Acute - Rapid onset of short duration.

Occurs in a limited region in the body (e.g., urinary tract infection).

Convalescence: Tissue repair, return to healthĬlassification of Infections By Location:.

Prodromal: Appearance of vague symptoms not all diseases have this stage.

Incubation: From time of infection until manifestation of symptoms can infect others.

Wounds, surgical sites, IV or drainage tube sites.

Eye, nares, mouth, vagina, cuts, scrapes.

Airborne: Via air conditioning, sweeping Portal of Exit:.

Direct – touching, kissing, sexual contact.

The Spread of Infection Mode of Transmission:

Food, floors, equipment, contaminated water.

Normal flora that become pathogenic Reservoir.

The Spread of Infection: Six Links Infectious agents

Pesticides, food additives, medications, industrial.

Parasitic worms found in soil transmitted via hand to mouth.

Organisms multiply in animal hosts and transmit to humans through bites.

Single celled organism spread by feces,.

Organisms that exist by feeding on organic matter.

Smallest of all pathogens replication within the host.One celled, multiply rapidly, classified by shape and how they cluster together.Protection against infection before, during and after a surgical procedure.technique or procedure which reduces the number of micro organisms and thus prevents the spread of disease.Medical and Surgical Asepsis Metropolitan Community College NURS 1510 Nancy Pares, RN, MSN
