Sterility check for surgical instruments

Floriane Tixier, Mélanie Garçon, Françoise Rochefort, Stéphane Corvaisier
BACKGROUND: The use of electrosurgery has expanded to a wide variety of surgical specialities, but it has also been accompanied by its share of complications, including thermal injuries to nontargeted tissues, caused by a break or defect in the insulation of the instrument's coat. The purpose of this study was to determine the prevalence and the location of insulation failures (IFs) in electrosurgical instruments, then to assess the necessity of routine IF testing. METHODS: Electrosurgical instruments were visually inspected and checked for IF using a high-voltage detector...

BACKGROUND: New Department of Health (England) Choice Framework for Local Policies and Procedures guidance (CFPP 0101) still states that ninhydrin can be used to check for efficient protein removal from surgical instruments processed in sterile services departments (SSDs). AIM: With the potential transfer of variant Creutzfeldt-Jakob disease (vCJD) via surgical procedures it is necessary to re-evaluate recommended methods for protein detection. METHODS: This paper reports studies on the sensitivity and applicability of ninhydrin for detecting proteins in laboratories and SSDs...

PURPOSE: The purpose of this study was to describe the validation process for assessing an instrument to assess residents' aseptic technique skills. METHODS: The validation study entailed comparisons of the performance of aseptic technique procedures between postgraduate year-1 (PGY-1) surgical residents and PGY-2/3 surgical residents. We also compared the performance of PGY-1 surgical residents from 2 different academic years for the same procedures. Finally, we compared the performance of novices (medical students) and experts (operating room nurses) in an effort to determine validity...

An essential component of any clinical intervention or clinically invasive procedure in the perioperative setting will involve the use of instruments. It is therefore essential that all practitioners in the perioperative setting are able to identify the instruments required for a case, for both preparation and checking purposes, be able to verify the sterility of the instrument and/or set, and be aware of the actions to be taken if any problems arise.

OBJECTIVE: To compare the failure rate (pregnancies) of a Pomeroy procedure and Filshie clips tubal occlusion at the time of Caesarean section. METHOD: This is a retrospective observational study done in a district general hospital in the UK. There were 290 sterilisations performed at the time of Caesarean section over the period of 1994-2007. Studied population included 203 Pomeroy procedures and 87 Filshie clips applications. Follow-up period ranged from 2 to 15 years...

Surgical instruments, whether single use or reusable, are defined by the University of Newcastle's Online Medical Dictionary as 'Hand held tools or implements used by health professionals for the performance of surgical tasks' (CancerWEB 1998). This definition, in its broadest terms, recognises that the inter-professional team (health professionals) are involved in the use, care and management of that tool or implement (performance of surgical tasks). Spry (2007) identifies that a surgical instrument could last 10 years if well made, carefully handled and appropriately used and that it is the responsibility of the surgical team and sterile services personnel to preserve and protect the life of each individual instrument...

A series of 145 laparoscopy port site infections due to Mycobacterium chelonae were found in 35 patients following laparoscopy at a single hospital over a six-week period. The contaminating source was ultimately identified as the rinsing water used for washing chemically disinfected instruments. The organism survived and grew within the biofilm at the bottom of disinfectant trays and within the outer sleeves of re-usable laparoscopic instruments. Remedial control measures included changing to ethylene oxide gas sterilization of laparoscopic equipment instead of chemical sterilization, thorough dismantling and manual precleaning of instruments, drying prior to gas sterilization, and random checks of environmental samples within the operating room complex for acid-fast bacilli...

Medical devices manufactured for implantation into humans must be free of any contamination with viable bacteria. However, remnants of dead bacteria and bacterial components alone may induce an inflammatory immune response. Pyrogen tests for such inflammatory contaminations are generally performed either by determining the content of lipopolysaccharide in rinsing solutions of batch samples by limulus amoebocyte lysate assay, by injecting the rinsing solutions into rabbits or by implanting batch samples into rabbits and measuring change of body temperature...

PURPOSE: To examine whether sterile water and brushes are necessary for hand washing before surgery. METHOD: Twenty-two operating room nurses were randomly divided into two groups as follows: 11 nurses who used 7.5% povidone iodine (PVI group) and another 11 nurses who used 4% chlorhexidine gluconate (CHG group) to wash their hands using the rubbing method. All the nurses were examined for bacterial contamination of their hands before and after surgical hand rubbing...

The Danish infection control guidelines dealing with transmissible spongiform encephalopathy (TSE) recognise that preventive measures to avoid iatrogenic transmission must be taken, though the risk for patients in Danish hospitals can be characterised as minimal. A minimal risk situation cannot meanwhile be maintained unless hospitals and other healthcare institutions are prepared and have effective and well-functioning decontamination procedures in place suited for the purpose. The guidelines recommend that staff both in the operating theatre and in the Central Sterile Supply Department (CSSD) must be able to apply the procedures needed for safe handling and decontamination of used instruments...

On the basis of experience gained from 6,000 laparoscopies (73% cholecystectomies) at the Moabit Hospital in Berlin, we carried out a cohort study to analyze the failure rate and decontamination of labeled "tracer" instruments processed in three test trays that were each subjected to 100 cycles. The majority of repairs focused on the functional parts of separable scissors and damaged or lost components. At 4%, the repair index after laparascopic use was less than that of a previously documented investigation period covering 1990 to 1996...

For effective management of clinical laboratory in spite of a shortage of medical technologists, we modified conventional analytical instruments on the market, and developed the automatic transport mechanism and the robotic analytical instruments to suit the operational needs of our laboratory. Consequently, we succeeded in designing a system in which the results for 89% of all the tests ordered were reported within 60 minutes after the time when the specimens were received at the laboratory. As a result of this laboratory automation system, medical technologists were spared from their routine work, and their expertise was now diverted to the other duties like examination for microbes in hospital facilities, evaluation for sterilization of surgical instruments, and maintenance of measuring apparatuses in the operating rooms...

The possible causes of intraocular infections after microsurgical operations on the eye are discussed. Extensive experiments were carried out to investigate infection caused by the patient himself, by the surgeon and by the surgical surroundings. To consider the different aspects involved in "perioperative prophylaxis", we examined the preoperative, intra- and postoperative periods. Conjunctival diagnostics, disinfection of the conjunctival sac, and the operating area were investigated for the preoperative period...
