Sterility monitor for surgical instruments

Isabel Veiga-Malta
It is well known that the common goal of all central sterile supply departments (CSSDs) is to prevent healthcare-associated infections. Such infections entail high costs to society, not only economic but also social. Therefore, delivering safe medical devices and guaranteeing a positive contribution to the control of healthcare-associated infections form the main responsibilities of a CSSD. The monitoring of the effectiveness of medical device cleaning processes is highly recommended. However, ensuring a flawless environment for the preparation, assembly, and packaging of medical devices and clean handling of sterilized items is crucial to achieving the goal of safe medical devices...

Instruments and implants sterilized by immediate use steam sterilization (IUSS), formerly called flash sterilization, can increase the patient's risk for acquiring a surgical site infection. We implemented a hospital-wide initiative to determine the reasons that perioperative personnel use IUSS to sterilize items and then designed a program to reduce the hospital's rates. Program initiatives included educating perioperative personnel, improving scheduling processes, holding vendor discussions, purchasing additional instrument sets, and transitioning from paper wrap to metal containers for instrument sets...

Using sterile technique helps prevent the surgical environment from becoming contaminated and thus can help reduce the incidence of surgical site infection. The AORN "Recommended practices for sterile technique" provides guidance for setting up, maintaining, and monitoring a sterile field. Topics include the use of surgical attire and personal protective equipment; appropriate selection and evaluation of surgical gowns, gloves, and drape products for each procedure; use of sterile technique to don sterile gowns and gloves; appropriate methods for establishing and monitoring a sterile field; and techniques to ensure that items such as surgical instruments that may be contaminated are not used...

BACKGROUND: Surgical instrument processing is critical to safe, high-quality surgical care but has received little attention in the medical literature. Typical hospitals have inventories in the tens of thousands of surgical instruments organized into thousands of instrument sets. The use of these instruments for multiple procedures per day leads to millions of instrument sets being reprocessed yearly in a single hospital. Errors in the processing of sterile instruments may lead to increased operative times and costs, as well as potentially contributing to surgical infections and perioperative morbidity...

Sterile magnetic drapes are frequently used during surgery to hold metal instruments on the sterile field. Magnetic fields may potentially interfere with the function of cardiovascular implantable electronic devices such as pacemakers and implantable cardioverter defibrillators. In this study, we evaluated the potential magnetic interference of magnetic drapes on pacemaker function. A magnetic drape with 70 magnets was placed with its approximate center over the pacemaker of 50 patients during their visit to the cardiology clinic...

A portable, fast gas chromatographic method for the direct measurement of part-per-billion level of ethylene oxide in medical work place atmospheres is introduced. Ethylene oxide is a chemical of significance in life science for its critical role as a highly effective sterilizing agent for heat sensitive surgical instruments. However, ethylene oxide is highly flammable, a suspected human carcinogen, is mutagenic, and henceforth, requires close monitoring. The approach incorporates a temperature-programmable silicon micromachined gas chromatograph for the fast separation of ethylene oxide from airborne organic interferences...

This protocol for in vivo solid-phase microextraction (SPME) can be used to monitor and quantify intravenous concentrations of drugs and metabolites without the need to withdraw a blood sample for analysis. The SPME probe is inserted directly into a peripheral vein of a living animal through a standard medical catheter, and extraction occurs typically over 2-5 min. After extraction, the analytes are removed from the sorbent and analyzed by, for example, liquid chromatography-tandem mass spectrometry. It has been validated in comparison with conventional blood analysis, and we describe here the in vitro experiments typically conducted during method development...

BACKGROUND: The correction of trunk deformity is crucial in scoliosis surgery, especially for the patient's self-image. However, direct visualization of external scoliotic trunk deformity during surgical correction is difficult due to the covering draping sheets. METHODS: An optoelectronic camera system with 10 passive markers is used to track the trunk geometry of 5 scoliotic patients during corrective surgery. The position of 10 anatomical landmarks and 5 trunk indices computed from the position of the passive markers are compared during and after instrumentation of the spine...

Processing surgical instruments in preparation for surgery is a complex multistep practice. It is impractical to culture each and every item to determine sterility; therefore, the best assurance of a sterile product is careful execution of every step in the process coupled with an ongoing quality control program. Perioperative staff nurses and managers responsible for instrument processing, whether for a single instrument or multiple sets, must be knowledgeable with regard to cleaning; packaging; cycle selection; and the use of physical, chemical, and biological monitors...

About 8,000 people die every year in Taiwan as a result of nosocomial infection. Clinically, there is a high possibility for patients to contract nosocomial infection if medical equipment is not completely sterilized. In order to provide care and safety to patients in the operating room, increase management effectiveness and efficiency, and to reduce equipment operating costs, a project was developed to improve operating room management through data collection and analysis. A computerized barcode operational system for packages of surgical instruments was developed and executed throughout an entire operating room...

Modern hospital sterile service departments (SSDs) routinely inspect instruments visually to assess the degree of contamination present after the washer/disinfector cycle. We aimed to test the effectiveness and reliability of this method. Surgical instrument sets were obtained from nine anonymous National Health Service (NHS) Primary Care Trust SSDs to investigate the efficacy of 'in-place' cleaning procedures. The instruments were first inspected visually, followed by a novel technique called episcopic differential interference contrast microscopy...

The ineffective cleaning of surgical instruments may be a vector for the transmission of hospital-acquired infections. The aim of this research was to investigate whether further decontamination procedures need to be instigated in sterile-service departments (SSDs) to reduce the risk of nosocomial illnesses, such as endotoxemia, sepsis, or iatrogenic Creutzfeldt-Jakob disease (to date, 1,147 cases of confirmed Creutzfeldt-Jakob disease deaths in the United Kingdom since 1990 have been reported). Instrument sets were obtained from nine anonymous United Kingdom National Health Service (NHS) primary care trust SSDs...

Hospital sterile service departments (SSDs) currently rely on simple visual confirmation of cleanliness as an assessment of the efficacy of cleaning surgical instruments. The inherent inability to monitor low levels of infectious or proteinaceous contamination on surgical instruments creates the possibility that highly dangerous and robust biological agents may remain infectious and undetected even after standard cleaning and sterilization procedures have been employed. This paper describes the development of a novel microscopy technique, episcopic differential interference contrast microscope, combined with the fluorescent reagent, SYPRO Ruby, to rapidly detect brain tissue protein to below 400 pg/mm(2) on an instrument surface...
