Sterile technique requires a combination of meticulous hand washing, creation of a sterile field, using long-lasting antimicrobial cleansing agents such as betadine, donning sterile gloves, and using sterile devices and instruments. It is the standard of care for surgical procedures, invasive wound management, and central line care. ![]() Sterile technique (also called surgical asepsis) seeks to eliminate every potential microorganism in and around a sterile field while also maintaining objects as free from microorganisms as possible. In the most simplistic terms, asepsis is creating a protective barrier from pathogens, whereas sterile technique is a purposeful attack on microorganisms. Both asepsis and sterility are closely related, and the shared concept between the two terms is removal of harmful microorganisms that can cause infection. There is often misunderstanding between the terms aseptic technique and sterile technique in the health care setting. These potentially infectious, microscopic organisms can be present in the environment, on an instrument, in liquids, on skin surfaces, or within a wound. In the clinical setting, aseptic technique refers to the purposeful prevention of microbe contamination from one person or object to another. The word “aseptic” literally means an absence of disease-causing microbes and pathogens. When performed properly, aseptic technique prevents contamination and transfer of pathogens to the patient from caregiver hands, surfaces, and equipment during routine care or procedures. For example, a nurse administering parenteral medication or performing urinary catheterization uses aseptic technique. Given that the role of the perioperative nurse is paramount in maintaining surgical integrity, and enhancing positive patient outcomes, strict adherence to surgical asepsis is vital to prevent SSIs and other complications.In addition to using standard precautions and transmission-based precautions, aseptic technique (also called medical asepsis) is the purposeful reduction of pathogens to prevent the transfer of microorganisms from one person or object to another during a medical procedure. ![]() ![]() The findings showed areas of compliance and noncompliance with the principles of asepsis. Perioperative scrub RNs were less likely to wear shoe covers during surgical procedures than ORTs (M = 3.42 and 4.17 mdn = 3.00 and 5.00 respectively p =. The purpose of this study was to examine the practices of perioperative scrub personnel with surgical asepsis.Ī sizable percentage of participants indicated that they never or rarely observe breaches in the sterile field during surgery with regards to open suction drain systems (46.6% n = 41), closed suction drain systems (46.6% n = 41), suture material (39.7% n = 35), use of surgical instruments (37.5% n = 33), and prosthetic implants (56.8% n = 50). Perioperative nurses are expected to demonstrate strict adherence with asepsis principles to prevent surgical site infections (SSIs) as breaching of these principles poses a serious risk of infection to surgical patients.Ī descriptive survey was conducted with a convenience sample of 87 perioperative personnel to describe self-reported compliance with the principles of asepsis during surgery.
