INTRODUCTION: Various different learning methods are available for planning tuition regarding the introduction to surgical hand disinfection. These learning methods should help to organise and deal with this topic. The use of a video film is an alternative to conventional tuition due to the real presentation possibilities of practical demonstration. OBJECTIVE: This study examines by way of comparison which form of communication is more effective for learning and applying surgical hand disinfection for medical students in their first year of studies: video-based instruction or conventional tuition...

BACKGROUND: Several studies have shown that rubbing hands with an alcohol/chlorhexidine solution provides equivalent microbial decontamination to a conventional surgical scrub using aqueous chlorhexidine. However, the authors believe that these studies have methodological flaws that limit their applicability to the operating theatre environment. As such, a method was developed to compare products in an everyday operating theatre environment using working operating theatre personnel. AIM: To determine whether or not an alcohol/chlorhexidine rub is as efficacious as a traditional surgical scrub using a novel method...

Postoperative infection and sepsis remain a major cause of morbidity among patients undergoing surgery. Maintenance of strict asepsis is essential if post-operative infection and its consequences are to be minimized. In developing countries maintenance of asepsis in most operation theatres is limited to fumigation and mopping. Clinical trials have confirmed that 80-90 % of bacterial contaminants found in wound after surgery come from microbes present in air of operating theatre. A study was conducted to evaluate the microbiological contamination of maxillofacial operation theatres in India and its correlation to weekly fumigation...

In the presence of single-use airway filters, we quantified anaesthetic circuit aerobic microbial contamination rates when changed every 24 h, 48 h and 7 days. Microbiological samples were taken from the interior of 305 anaesthetic breathing circuits over a 15-month period (3197 operations). There was no significant difference in the proportion of contaminated circuits when changed every 24 h (57/105 (54%, 95% CI 45-64%)) compared with 48 h (43/100 (43%, 95% CI 33-53%, p = 0.12)) and up to 7 days (46/100 (46%, 95% CI 36-56%, p = 0...

Portable ultrasound machines are frequently used in operating theatres for peripheral single-shot nerve block procedures. This equipment must be decontaminated by reducing the microbial load to a sufficient level to reduce the risk of nosocomial infection. In our institution we use a simple three-step decontamination protocol utilising 70% isopropyl alcohol as chemical disinfectant. We performed a prospective, quality assurance study to assess the efficacy of this protocol, as it is unclear if this is suitable for disinfecting semi-critical equipment...

OBJECTIVE: Blood pressure (BP) cuffs are potential vectors for transmission of multi-resistant organisms (MROs). The present study aims to determine MRO colonisation rates in BP cuffs from areas of high patient flow as an assessment of the quality of disinfection and infection control practices. METHODS: BP cuffs in the ED, high dependency unit (HDU) and operating theatres (OT) were prospectively examined after routine disinfection procedures. Swabs collected from the inner and outer surfaces of BP cuffs during inter-patient intervals were plated onto replicate organism detection and counting, methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE) chromogenic agar plates to detect rates of bacterial, MRSA and VRE colonisation, respectively...

Infection rates after arthroplasty surgery are between 1-4 %, rising significantly after revision procedures. To reduce the associated costs of treating these infections, and the patients' post-operative discomfort and trauma, a new preventative method is required. High intensity narrow spectrum (HINS) 405 nm light has bactericidal effects on a wide range of medically important bacteria, and it reduced bacterial bioburden when used as an environmental disinfection method in a Medical Burns Unit. To prove its safety for use for environmental disinfection in orthopaedic theatres during surgery, cultured osteoblasts were exposed to HINS-light of intensities up to 15 mW/cm2 for 1 h (54 J/cm2)...

INTRODUCTION: The surgeon uses different methods of surgical hand antisepsis with the aim of reducing surgical site infections. To date, there are no local studies comparing the efficacy of iodine hand scrub against newer alcohol-based hand rubs with active ingredients. Our pilot study compares a traditional aqueous hand scrub using 7.5% Povidone iodine (PVP-I) against a hand rub using Avagard: 61% ethyl alcohol, 1% chlorhexidine gluconate. The outcome measure is the number of Colony Forming Units (CFU) cultured from 10-digit fingertip imprints on agar plates...

Current evidence does not favour constructional over functional separation of septic and aseptic surgical procedures in terms of overall hygiene maintenance and incidence of skin and soft tissue infections. In both laminar and turbulent flow air operating theatres, air is not a relevant source of pathogens if surface disinfection is carried out properly.Final cleaning after a septic procedure includes a thorough wipe-disinfection of all potentially contaminated near and distant surfaces, including maintaining the necessary and effective exposure time of the chosen surface disinfectant...

Bone and tissue allografts are widely used in transplantation. The increasing demand for safe allografts must be met, while minimizing disease transmission. We analysed the incidence and potential risk factors of allograft contamination and the effectiveness of disinfection, by reviewing 22 years of tissue bank activity and 474 donor procurements. We also compared different disinfection procedures used over the 22 years. The overall contamination rate was 10.1%. Risk factors were related to the donor or procurement method...

BACKGROUND: The current prevalence of healthcare-associated infections (HCAIs) is a major public health concern. Patient contact in the operating theatre (OT) can contribute to HCAI via microbial contamination. The application of hand hygiene is effective in reducing infection rates. Limited data are available on adherence to hand-hygiene guidelines by OT staff. METHODS: Covert direct observations of OT staff at an academic medical centre were performed by a single, trained observer...

In healthy volunteers, surgical hand rubbing with Sterillium for 1.5min has been shown to be as effective as a 3min procedure. The aim of this study was to assess whether this result was reproducible under in-use conditions. During nine weeks in the ambulatory surgery theatre of a 750-bed tertiary care university hospital, the two surgical hand-rubbing procedures were compared with each other, and with a hand-scrubbing procedure using a povidone-iodine (4%) scrub prior to and after 25 different surgical operations for each...

Infection remains a devastating complication of joint replacement surgery causing a significant burden to both patient and surgeon. However, despite exhaustive prophylactic measures, intraoperative contamination still occurs during cemented arthroplasty with current infection rates of 1-2%. A study was undertaken to determine the incidence of perioperative contamination in cemented arthroplasty patients, to identify contaminating organisms, to identify contaminated regions within the operative wound, to identify factors associated with increased contamination, and finally to assess the medium-term clinical outcome in patients with confirmed intraoperative wound contamination...

BACKGROUND: In most surgical theatres, a 1 min or even longer hand wash is routine as part of the pre-operative hand disinfection. But its benefit has recently been seen critically. METHODS: We have therefore investigated the effect of a 1 min hand wash on skin hydration and on the efficacy of consecutive surgical hand rubbing with three standard alcohols (60% propan-1-ol, 60% propan-2-ol, 80% ethanol; all v/v) on the resident hand flora. Three types of treatment were performed: (i) a 1 min pre-wash before surgical hand disinfection, (ii) no pre-wash before surgical hand disinfection and (iii) no pre-wash but use of a brush for 1 min during disinfection procedure...
