“…The contamination rates from previous studies since 2008 [12,16,17,19-21], when the US CDC suggested disinfection instructions, were 42.0 to 57.3% of laryngoscope blades and 69.2 to 86.0% of handles. These values were more than those of the present study were, and this result may be caused by differences in each institution’s disinfection instructions, specimen collection method, sample delivery, culture method, and type of department that used a laryngoscope.…”

ObjectivesTo identify bacterial contamination rates of laryngoscope blades and handles stored in emergency crash carts by hospital and area according to the frequency of intubation attempts.MethodsOne hundred forty-eight handles and 71 blades deemed ready for patient use from two tertiary hospitals were sampled with sterile swabs using a standardized rolling technique. Samples were considered negative (not contaminated) if no colonies were present on the blood agar plate after an 18-hour incubation period. Samples were stratified by hospital and according to the frequency of intubation attempts (10 attempts per year) using the χ2-test and Fisher exact test.ResultsOne or more species of bacteria were isolated from 4 (5.6%) handle tops, 20 (28.2%) handles with knurled surfaces, and 27 (18.2%) blades. No significant differences were found in microbial contamination levels on the handle tops and blades between the two hospitals and two areas according to the frequency of intubation attempts. However, significant differences were found between the two hospitals and two areas in the level of microbial contamination on the handles with knurled surfaces (p<0.05).ConclusionsProtocols and policies must be reviewed to standardize procedures to clean and disinfect laryngoscope blades and handles; handles should be re-designed to eliminate points of contact with the blade; and single-use, one-piece laryngoscopes should be introduced.

“…Howell et al conducted an audit, three laboratory comparative studies, and a repeat audit to establish an effective cleaning regimen for laryngoscope handles. In the audit, the researchers obtained microbiological cultures from 55 patient‐ready laryngoscope handles in the operating suites, neonatal intensive care unit, and emergency department of a hospital in the United Kingdom.…”

“…The researchers found no growth on 32 (58.0%) of the laryngoscope handles, one species of bacteria on 14 (26.0%) of the handles, and two species of bacteria on 9 (16.0%) of the handles. The researchers identified the bacteria as coagulase‐negative staphylococci, Corynebacterium species, Bacillus species, and Pseudomonas aeruginosa …”

“…The researchers concluded that because of the residual effect of the CHG wipes, disinfection of laryngoscope handles with CHG germicidal wipes was superior to disinfection with CDBAC wipes. The researchers also concluded that if laryngoscope handles are routinely disinfected with germicidal wipes, they should be processed by steam sterilization at established intervals as well …”

Contamination and Disinfection of Rigid Laryngoscopes: A Literature Review

This article reviews current literature about the contamination of laryngoscope blades and handles, disinfection practices for laryngoscope blades and handles, and environmental effects and costs of reusable and single‐use laryngoscopes. This review shows that inadequately processed rigid laryngoscopes may have the ability to transmit infections to patients and health care personnel. Although the laryngoscope handle has been considered a noncritical item that contacts only intact skin, health care team members should consider both the laryngoscope blade and handle as semicritical items and process them by high‐level disinfection (HLD) or steam sterilization according to manufacturer's instructions. The fewest environmental effects occur when a reusable stainless‐steel laryngoscope is processed by HLD. Laryngoscope costs are lower for processing reusable laryngoscope handles and blades by HLD and highest for single‐use laryngoscopes. Evidence‐based guidelines are needed to specify and standardize best practices for processing rigid laryngoscopes.

“…Numerous studies have demonstrated that contamination of laryngoscope blades and handles is common. [252627] The fact that knurled handles of laryngoscopes also get contaminated is often overlooked by most of us. Handles should be washed, disinfected and if suitable, sterilised after every use.…”

The main purpose of this review article is to bring up what has been known (practiced) about decontamination, disinfection, and sterilisation of anaesthetic equipment. It also discusses how this evidence-based information on infection prevention and control impacts care of patient in routine anaesthesia practice. This review underscores the role played by us, anaesthetists in formulating guidelines, implementing the same, monitoring the outcome and training post-graduate trainees and coworkers in this regard. The article re-emphasises that certain guidelines when followed strictly will go a long way in reducing transmission of hospital acquired infection between patient and anaesthetist or between patients. Anaesthetists do not restrict their work to operating room but are involved in disaster management, interventional radiological procedures and in trauma care. They should ensure that the patients are cared for in clean and safe environment so as to reduce healthcare associated infections (HCAIs) simultaneously taking preventive measures against the various health hazards associated with clinical practice. They should ensure that the coworkers too adopt all the preventive measures while delivering their duties. For this review, we conducted literature searches in Medline (PubMed) and also searched for relevant abstracts and full texts of related articles that we came across. There is much to be learned from the western world where, health care organisations now have legal responsibility to implement changes in accordance with the newer technology to reduce health care associated infection. There is a need to develop evidence-based infection prevention and control programs and set national guidelines for disinfection and sterilisation of anaesthesia equipment which all the institutions should comply with.

Chlorhexidine to maintain cleanliness of laryngoscope handles

Abstract: Decontamination with Sani-Cloth CHG 2% wipes confers additional advantages over routine autoclaving or handle disposal, due to a residual effect. Autoclaving handles may be desirable on a scheduled basis and if Clostridium difficile is encountered.
