Veterinary Surgical Nursing and Operating Room Protocols Flashcards

Vocabulary flashcards covering key definitions, surgical suite management, sterile field principles, aseptic techniques, and antiseptics/disinfectants from the lecture.

Essential Skills

Program requirements that students must pass with a $75\%$ or higher in both the lab and lecture sections to pass the course.

Pass-through Cabinet

A dual-access cabinet built into an operating room wall that allows items to be stocked or loaded from outside without entering the surgical suite.

Dirty Surgery

A surgical procedure involving areas with high bacterial counts or potential infection, such as gastrointestinal foreign body removals or pyometras.

Clean Surgery

A surgical procedure carried out under strict aseptic conditions on non-infected, uninflamed tissue, such as orthopedic bone or joint replacements.

Wet Mop / Damp Mop

A specialized rubber or static cleaning broom used in an operating room to capture dust and hair without dispersing airborne particles.

Scrubbed-in Team

Sterile surgical personnel, including the primary surgeon and surgical assistant, directly involved in performing the operation.

Circulating Assistant

A non-sterile assistant wearing clean scrubs, cap, mask, and shoe covers who prepares the patient, retrieves supplies, and opens sterile packs for the scrubbed-in team.

Sterile Field

The specified sterile area directly over the draped patient and instrument tray extending upward to the ceiling, which must only be touched by sterile personnel and items.

Sterile Zone (Personnel)

On a scrubbed-in individual, the area of the body considered sterile, extending from the waist to the shoulders and from the elbows to the fingertips on the front side.

Wicking

The process where moisture penetrates paper or fabric drapes or wraps, drawing contaminants into a sterile pack or field.

Medical Asepsis

Clean technique aimed at reducing the number and transfer of microorganisms during non-surgical procedures like oral medication or tube feeding.

Surgical Asepsis

Sterile technique aimed at completely eliminating microorganisms from an area, personnel, and equipment during surgical procedures.

Aseptic Technique

The practice and methods used to prevent contamination of a sterile environment, person, or equipment.

Asepsis

The state of being free from pathogenic microorganisms.

Sepsis

The presence of pathogenic microorganisms or toxins in living tissue or the bloodstream, leading to infection.

Organic Material

Biological matter originating from the body—such as blood, feces, saliva, hair, and urine—that can deactivate or reduce the efficacy of disinfectants and antiseptics.

Lavage

The therapeutic flushing of a body cavity or surgical site with sterile fluid, such as rinsing the abdomen following intestinal surgery.

Nosocomial Infection

An infection acquired by a patient during treatment within a hospital or healthcare facility.

Cytotoxic

Toxic or destructive to living cells.

Contact Time

The exact duration a chemical disinfectant or antiseptic must remain in physical contact with a surface to effectively kill target pathogens.

Residual Activity

The ongoing, persistent antimicrobial action of a chemical agent that remains on a surface or skin over time after application.

Iodine (Povidone-Iodine)

An antiseptic effective against bacteria with a $4$ to $6\text{ hour}$ residual activity, but cytotoxic to cells if used undiluted and inactivated by organic matter.

Chlorhexidine

A rapid-acting antiseptic with long residual activity that is less affected by organic material than iodine, but forms precipitates when mixed with electrolyte solutions such as LRS.

Hydrogen Peroxide ($H_2O_2$)

A light-sensitive antiseptic and disinfectant ($3\%$ solution) that destroys microbes via oxidation and removes blood stains, but damages healing tissue cells.

Alcohol

A fast-evaporating antiseptic with short residual activity that dries quickly and is unsuitable for open wounds or mucous membranes due to tissue irritation.

Disinfectant

A chemical agent designed to destroy or inhibit microorganisms on inanimate surfaces and objects.

Antiseptic

A chemical agent applied directly to living tissue or skin to inhibit or destroy microorganisms.

Quaternary Ammonium Compounds (Quats)

Non-toxic cationic surface disinfectants effective against bacteria and viruses, but limited against bacterial spores.

Glutaraldehyde (Cidex)

A high-level chemical cold sterilant used for delicate equipment like endoscopes, requiring $20\text{ minutes}$ of contact time and inactivated by organic matter.

Rescue

An accelerated hydrogen peroxide disinfectant commonly used in veterinary settings that is fear-free, safe for animal tissues, and effective against Parvovirus, ringworm, and kennel cough.
