Source: Kay Stewart, RVT, RLATG, CMAR; Valerie A. Schroeder, RVT, RLATG. University of Notre Dame, IN In 1959 The 3 R's were introduced by W.M.S. Russell and R.L. Burch in their book The Principles of Humane Experimental Technique. The 3 R's are replacement, reduction, and refinement of the use of animals in research. The use of cell lines and tissue cultures that originated from research animals is a replacement technique, as it allows for many experiments to be conducted in vitro. Harvesting...

2025
This study presents a novel surgical technique for implanting a biomimetic artificial intervertebral disc (BioAID). The method ensures precise placement and stability, aiming to restore cervical spine function using a goat model. This technique shows promise for clinical application in both human and canine patients suffering from cervical spine myelopathy.

2026
Medial canthopexy allows correction of the position and fixation of the medial canthal tendon. Due to the technical difficulties of this procedure, there is a need for a detailed protocol for educational purposes. Here, we describe a standardized reproducible technique for bilateral medial transnasal canthopexy by an orbitonasal approach.

2023
Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease. Cleaning The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

FAQs
These measures address microbial transfer from the surgical team to the operative field. Hand antisepsis reduces microorganisms on the hands, while sterile gloves and gowns add protective barriers between personnel and the patient or instruments. Used together, they support aseptic preparation and help preserve the controlled conditions required for invasive procedures.
They control different potential sources of contamination. Instrument sterilization prepares equipment before it contacts the surgical field, whereas skin preparation addresses microorganisms present at the patient’s operative site. Including both measures creates more complete aseptic preparation, limiting opportunities for microbial transfer from equipment or the patient’s skin during surgery.
A controlled sterile field limits contact between sterile materials and potential sources of microorganisms throughout the procedure. Its value extends beyond initial preparation because contamination can occur during ongoing surgical activity. Maintaining the field therefore supports consistent infection prevention while tissues are open and instruments or implanted devices may be exposed.
These circumstances increase the consequences of microbial contamination during an invasive procedure. Open tissues provide direct access to the surgical site, implanted devices are present within the operative environment, and vulnerable patients may have greater difficulty tolerating procedure-related infection. Consistent aseptic preparation is therefore particularly important in these settings.
Preparation includes hand antisepsis, sterile gloves and gowns, sterilized instruments, patient skin preparation, and establishment of a controlled sterile field. These components address personnel, equipment, the operative site, and the surrounding procedural environment. Their coordinated use creates the aseptic conditions needed before and during surgery.
Its use extends across invasive procedures performed in operating rooms and other procedural settings. The same infection-prevention principles support both minor operations and major surgery, although the clinical circumstances may differ. This broad application makes sterile technique relevant wherever open tissues, surgical instruments, or implanted devices are part of care.
Consistent application reduces the risk of contamination and procedure-related infection while strengthening overall surgical safety. It also provides a structured infection-prevention approach for operating rooms and other procedural environments. By addressing preparation and microbial transfer together, the technique supports safer invasive care across a range of medical procedures.
