RESUMO

PURPOSE: This study aimed to evaluate the impact of oral care and use of chlorhexidine gluconate on the prevention of ventilator-associated pneumonia (VAP) in patients admitted to an intensive care unit (ICU). MATERIALS AND METHODS: An evaluation was performed on 229 patients admitted to ICU in 2012 (before implementation of oral care protocol) and 329 in 2013 (after the protocol). Oral care was based on the removal of secretions from the oral cavity with 0.12% chlorhexidine solution for brushing and sterile gauze for cleaning before a new aspiration. The cases of VAP were evaluated by observing respiratory signs, radiological changes, and culture and laboratory results. The following data were also analysed: gender, length hospital of stay, mechanical ventilation, use of antibiotics and aetiological agent of infection. RESULTS: There was a tendency towards lower risk of development of VAP after application of oral care protocol (odds ratio = 0.64-95% CI: 0.39-1.04). There was also a reduction in the incidence of early pneumonia (up to 72 h of hospitalisation). With regard to the aetiological agent of infections, although Gram-negative bacteria predominated in the two periods studied, there was a decrease in the cases of Staphylococcus aureus infection. CONCLUSION: Oral care protocol has statistically significantly reduced the risk of developing early VAP in ICU patients, thus demonstrating the importance of multidisciplinary teamwork for hospitalised patients.

RESUMO

Objetivo: Avaliar a redução microbiana após antissepsia cirúrgica das mãos dos cirurgiões, realizada com preparação alcoólica, em diferentes tempos. Método: Estudo de prevalência, pragmático, de campo, realizado em hospital terciário do Brasil. Coletaram-se amostras microbiológicas das mãos de 54 cirurgiões após lavagem simples, para determinar a flora microbiana basal e, após a antissepsia cirúrgica alcoólica, para avaliar a redução microbiana imediata. Categorizaram-se os resultados da redução microbiana em redução leve (até 50% de redução da flora bacteriana), moderada (de 51 a 80%) e alta (acima de 80%). A pesquisa foi submetida e aprovada pelo Comitê de Ética e Pesquisa da instituição hospitalar privada, sede do estudo, e da instituição de ensino superior federal. Resultados: Nas técnicas realizadas em menos de 90 segundos, houve 80% de redução severa, 6,7% de redução moderada e 13,3% de redução leve. Nas técnicas desempenhadas em mais de 180 segundos, todas as amostras apresentaram redução de contagem bacteriana, o que não ocorreu em tempos menores de antissepsia. Conclusão: Quando a técnica e o tempo recomendados são seguidos, maior é a redução bacteriana, em comparação aos tempos menores.


Objective: To evaluate the microbial reduction after surgical hand antisepsis performed with alcohol solution at different application times among surgeons. Method: This is a pragmatic prevalence field study carried out in a Brazilian tertiary hospital. Microbiological samples were collected from the hands of 54 surgeons after simple washing to determine the baseline microbial flora and after surgical antisepsis with an alcohol solution to evaluate the immediate microbial reduction. We categorized the microbial reduction results as mild (up to 50% bacterial flora reduction), moderate (51 to 80%), and high (more than 80%). The research was submitted to and approved by the Research Ethics Committee of the private hospital (study site) and the federal institution of higher education. Results: Techniques performed in less than 90 seconds showed an 80% high reduction, 6.7% moderate reduction, and 13.3% mild reduction. In applications that lasted more than 180 seconds, all samples presented bacterial count reduction, which did not occur in shorter antisepsis times. Conclusion: When the recommended technique and time are followed, the bacterial reduction is greater compared to lower durations.

RESUMO

The efficacy of an antisepsis protocol comprising chlorhexidine gluconate and ethyl alcohol in combination with prophylactic antimicrobial therapy in controlling surgical site infection in horses was studied. To that purpose, seven mixed breed horses received potassium penicillin and gentamicin at least 30 minutes prior to surgery. The surgical site was scrubbed with chlorhexidine gluconate and rinsed with ethyl alcohol. Samples were collected at four time points: (A) - before and (B) - immediately following shaving of the hair coat, (C) - at the end of antisepsis procedures, and (D) - at the end of the surgical procedure. Duration of surgery was recorded. Samples were cultured in three different culture mediums: Mitis Salivarus (Streptococcus sp.), Staphylococcus 110 (Staphylococcus sp.), and Mac Conkey (Enterobacteria). A high level of bacterial growth was observed in all culture mediums at (A) and (B), with no bacterial growth in (C). Staphylococcus sp. growth was observed in (D) in a single patient whose surgical procedure lasted for 120 minutes. Shaving of the hair coat reduced microbial flora on the surface of the skin. Antisepsis in combination with prophylactic antimicrobial therapy was effective in controlling surgical site infection in elective procedures with an average duration of 90 minutes.(AU)


Objetivou-se averiguar a eficácia do protocolo de antissepsia com clorexidina degermante e álcool etílico hidratado 70%, em associação com terapia antimicrobiana profilática, no controle microbiano do foco cirúrgico de equinos submetidos a procedimentos cirúrgicos. Foram utilizados 07 cavalos adultos de raças variadas, onde ambos receberam o mesmo tratamento (terapia antimicrobiana profilática e antissepsia com clorexidina degermante 2% e álcool etílico hidratado 70%), coletando-se amostras em quatro tempos distintos [(A - antes da tricotomia), (B - imediatamente após tricotomia), (C - ao término da antissepsia), (D - ao término do procedimento cirúrgico)]. O tempo de cada procedimento cirúrgico foi contabilizado. Foram utilizados três meios de cultura diferentes, cada um com especificidade para um tipo de crescimento bacteriano. Constatou-se alta incidência de crescimento bacteriano nos três meios utilizados nos tempos de coleta A e B. Para o tempo C, não foi observado crescimento bacteriano. No tempo D averiguou-se crescimento bacteriano do tipo Staphylococcus sp. em um único paciente, cujo tempo cirúrgico foi de 120 minutos de duração. Desta forma, a tricotomia reduziu a carga microbiana na superfície da pele. A antissepsia associada à terapia antimicrobiana profilática mostrou-se eficaz no controle microbiano do foco cirúrgico em procedimentos eletivos, com duração média de 90 minutos.(AU)

RESUMO

BACKGROUND: Cardiac implantable electronic device (CIED) infection, a major complication of a CIED implant procedure, can prolong hospitalization and cause mortality. AIM: To evaluate the efficacy of a bundled skin antiseptic preparation for preventing infection after implantation of a complex CIED. METHODS: This study analysed 1163 consecutive patients who had received a bundled skin antiseptic preparation before CIED implantation from July 2012 to December 2017. According to the complexity of the CIED implant procedure, the patients were divided into a complex CIED group (N = 370) and a non-complex CIED group (N = 793). A complex procedure was defined as a pacemaker replacement, implantation of implantable cardioverter defibrillator and cardiac resynchronization therapy, device upgrade, or lead revision. FINDINGS: During a mean follow-up of 2.9 ± 1.7 years, CIED infection developed in 15 patients (1.3%), and the incidence of minor and major infection was 1.1% and 0.2%, respectively. The incidence of CIED infection did not significantly differ between the complex CIED group and the non-complex CIED group (1.1% vs 1.4%, respectively; non-significant). Multivariate analysis indicated that procedural complexity was not an independent predictor of CIED infection. After 2:1 propensity score matching, the matched non-complex CIED group and the matched complex CIED group still showed no significant difference in the incidence of CIED infection. CONCLUSION: Bundled skin antiseptic preparation is an effective and widely applicable strategy for decreasing infection risk after a complex CIED implantation.

RESUMO

Faced with the worldwide spread of multidrug-resistant (MDR) bacterial strains, together with a lack of any appropriate treatment, urgent steps to combat infectious diseases should be taken. Usually, bacterial components are studied to understand, by analogy, the functioning of human proteins. However, molecular data from bacteria gathered over the past decades provide a sound basis for the search for novel approaches in medical care. With this current work, we want to direct attention to inhibition of the vSGLT glucose transporter from Vibrio parahaemolyticus belonging to the sodium solute symporter (SSS) family, to block sugar transport into the bacterial cell and, as a consequence, to limit its growth. Potential bacteriostatic properties can be drawn from commercially available drugs developed for human diseases. This goal can also be reached with natural components from traditional herbal medicine. The presented data from the numerical analysis of 44 known inhibitors of sodium glucose symporters shed light on potential novel approaches in fighting Gram-negative multidrug-resistant microorganisms.

RESUMO

BACKGROUND: In Japan, blood cultures for children are performed by pediatric residents, and povidone-iodine (PI) is the recommended solution for skin preparation. Given that PI needs to be applied for 1.5-2 min before venipuncture, skin preparation may be suboptimal if this is not followed. In this study, we investigated the blood culture contamination rate after skin preparation with only 70% isopropyl alcohol (IPA) or IPA plus PI. METHODS: We performed a retrospective study of patients aged ≤6 years who provided blood cultures in the emergency department or pediatric ward. Patients with indwelling central venous catheter were excluded. We evaluated the impact of changing the method of skin preparation, comparing the traditional method using IPA plus PI between 2008 and 2010 (IPA + PI group) with the simplified method using only IPA between 2015 and 2017 (IPA group). RESULTS: A total of 5,365 blood culture samples were eligible for this study. Of these, 171 (3.2%) had an organism identified in blood culture. Of the blood culture-positive samples, 68 (1.3%) were true positive and 103 (1.9%) were contaminated. Thirty-eight (1.6%) of 2,407 cultures in the IPA group were contaminated, whereas 65 (2.2%) of 2,958 cultures in the IPA + PI group were contaminated (OR, 0.72; 95%CI: 0.48-1.07; P = 0.1). Coagulase-negative Staphylococcus grew significantly less in the IPA group (1.7% vs 1.0%, P = 0.02). CONCLUSIONS: A single application of 70% IPA may be the optimal skin preparation method for obtaining peripheral blood cultures from children in Japan.

RESUMO

INTRODUCTION: Short peripheral intravenous catheters (PVCs) are the most frequently used invasive medical devices in hospitals. Unfortunately, PVCs often fail before the end of treatment due to the occurrence of mechanical, vascular or infectious complications, which prolongs hospitalisation and increases healthcare costs and mortality.Prevention of these complications is mainly based on the respect of hygiene rules and the use of biocompatible catheters. In critically ill patients, 2% chlorhexidine-alcohol is superior to 5% povidone iodine-alcohol for skin preparation before central venous and arterial catheters; whether this finding can be extended to PVC inserted in the wards remains speculative. Similarly, the use of new technologies such as catheters designed to minimise blood exposure, zero-reflux needleless connectors, disinfecting caps and flushing PVCs before and after each medication administration to maintain catheter patency are of theoretical interest to prevent PVC failure, but little scientific data support their routine use. METHODS AND ANALYSIS: The CLEAN 3 study is an open-label, single-centre, randomised, two-by-two factorial trial. One thousand patients visiting our emergency department and requiring hospital admission in the wards will be randomised to one of four strategies according to skin preparation and devices used. The two primary endpoints will be (1) the incidence of infectious complications related to the catheters (colonisation, local infection or bloodstream infection) and (2) the time between catheter insertion and catheter failure defined as any premature removal of PVC before end of treatment, other than for routine replacement. ETHICS AND DISSEMINATION: This protocol has been approved by an independent ethics committee and will be carried out according to the principles of the Declaration of Helsinki and the Good Clinical Practice guidelines. The results of this study will be disseminated through presentation at scientific conferences and publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER: EudraCT 2018-A02535-50; NCT03757143.

RESUMO

Durante la atención sanitaria el paciente está expuesto a una gran variedad de microorganismos, por lo que la utilización de un máximo nivel de higiene en toda labor asistencial es fundamental para reducir la transmisión cruzada de toda aquella enfermedad infecciosa evitable. Los 3 mecanismos indispensables para la prevención de la infección en los centros sanitarios son la limpieza, la desinfección y la esterilización. El uso científico y racional de desinfectantes y antisépticos, así como la aplicación de forma correcta de las técnicas de asepsia en el cuidado de los pacientes y en la manipulación y el suministro de los materiales, son los ejes fundamentales en la prevención de las infecciones relacionadas con la asistencia sanitaria. El adecuado conocimiento de los conceptos y normas de uso de antisépticos y desinfectantes pone a disposición del trabajador la herramienta esencial que permite evitar la diseminación de agentes infecciosos, a la vez que le proporciona las bases científicas para su uso racional


During health care, the patient is exposed to a wide variety of microorganisms. Maximum hygiene in all care activities is therefore essential in order to reduce the cross-transmission of preventable infectious diseases. The 3 key mechanisms for the prevention of infection in health centers are cleaning, disinfection and sterilization. The scientific and rational use of disinfectants and antiseptics, and the correct application of aseptic techniques in the care of patients and in the handling and supply of materials are the fundamental considerations for the prevention of healthcare related infections. Adequate knowledge of the concepts and standards of use of antiseptics and disinfectants offers healthcare workers the essential tool needed to avoid the spread of infectious agents, while also establishing the scientific basis for their rational use

RESUMO

La higiene y el cuidado de la piel de los pacientes ingresados en las Unidades de Cuidados Intensivos (UCI) forman parte de los cuidados básicos. Desde hace unos años, existe la evidencia de colonización de la piel por patógenos multirresistentes, tanto de bacterias gramnegativas como grampositivas. El auge de infecciones nosocomiales por microorganismos multirresistentes ha llevado a evaluar el papel del uso de antisépticos, principalmente clorhexidina, como estrategia para disminuir el número de infecciones nosocomiales. En este artículo revisamos la situación actual de esta estrategia, así como un posicionamiento de los autores ante la extensión de esta estrategia en las UCI


Hygiene and skin care of patients admitted to the Intensive Care Unit (ICU) are part of basic care. For some years there has been evidence of skin colonization by multiresistant gramnegative and grampositive pathogens. The increase in nosocomial infections due to multiresistant microorganisms has led to evaluation of the role of the use of antiseptics, mainly chlorhexidine, as a strategy for reducing the number of such infections. This article reviews the current situation of this strategy, as well as the positioning of the authors in relation to the spreading of its use in ICUs

RESUMO

La infección de la herida quirúrgica es una de las principales complicaciones del paciente intervenido con cirugía y tiene graves consecuencias clínicas y económicas, sobre todo cuando afecta a implantes prostéticos o si está causada por bacterias multirresistentes. Dentro de las medidas preventivas, la preparación cutánea es uno de los elementos fundamentales. Las principales guías de práctica clínica recomiendan no retirar el pelo de la zona de la cirugía a no ser que interfiera con la intervención y, en caso de ser necesario, hacerlo con cortadora de uso único, lo más cercano en el tiempo a la cirugía. En cuanto a la ducha previa a la cirugía, la recomendación actual es hacerlo con un jabón (antimicrobiano o no) o con un producto antiséptico al menos la noche anterior. Para la preparación de la zona de incisión y el área de alrededor, se recomienda en general el empleo de antisépticos de base alcohólica, preferiblemente clorhexidina alcohólica por su alta actividad antibacteriana y su efecto residual prolongado, respetando de manera conveniente el tiempo de secado por evaporación


Surgical wound infection is one of the main complications of patients undergoing surgery and has significant clinical and economical consequences, especially when it affects prosthetic implants or is caused by multidrug resistant bacteria. Cutaneous preparation is one of the main preventive measures. Clinical practice guidelines recommend not to remove the hair from the surgery site unless it interferes with the operation, and that if removal proves necessary, it should be done with a single-use cutter, as close as possible to the time of surgery. With regard to preoperative showering, the current recommendation is to perform it with a soap (whether antimicrobial or otherwise) or an antiseptic product, at least the night before surgery. Regarding preparation of the incision area and surrounding zone, the use of an alcohol-based antiseptic is generally advised, preferably alcoholic chlorhexidine, due to its high antibacterial activity and prolonged residual effect, respecting the evaporation drying time

RESUMO

Las infecciones del tracto respiratorio inferior que afectan al paciente intubado constituyen un serio problema de salud por la morbimortalidad asociadas. Las microaspiraciones de las secreciones de la cavidad bucofaríngea constituyen el principal mecanismo fisiopatológico que explica el desarrollo de la neumonía y la traqueobronquitis asociadas a la ventilación mecánica. En todos los paquetes de medidas para prevención de estas infecciones, se incluye la antisepsia orofaríngea para disminuir la colonización orofaríngea. La clorhexidina es el antiséptico más evaluado en ensayos clínicos y metaanálisis que concluyen que la higiene bucal con clorhexidina reduce la incidencia de neumonía asociada a ventilación mecánica, siendo mayor la eficacia cuando se administra al 2%. Sin embargo, 2metaanálisis han alertado sobre un posible aumento de mortalidad cuando se emplea la clorhexidina como antiséptico oral. Eso nos lleva a recomendar su uso pero extremando la precaución en su aplicación para impedir aspiración de la misma


Lower respiratory tract infections in the intubated patient constitute a serious health problem due to their associated morbidity and mortality. Microaspiration of the buccopharyngeal secretions is the main physiopathological mechanism underlying the development of pneumonia and tracheobronchitis in intubated patients. All care bundles designed to prevent these infections include the use of antiseptics to reduce buccopharyngeal colonization. Chlorhexidine is the antiseptic most frequently assessed in clinical trials and meta-analyses that conclude that oral hygiene with chlorhexidine reduces the incidence of ventilator-associated pneumonia - maximum effectiveness being achieved when the product is administered at a concentration of 2%. However, 2meta-analyses have warned of a possible increase in mortality when chlorhexidine is used as an oral antiseptic. We therefore recommend its use but with extreme caution during application in order to avoid aspiration of the antiseptic

RESUMO

El hemocultivo es el principal método de diagnóstico etiológico de la bacteriemia, pero los falsos positivos son relativamente frecuentes, fundamentalmente por contaminación de origen cutáneo en el momento de extracción de la muestra. La correcta antisepsia cutánea es importante para disminuir la carga bacteriana y las posibilidades de contaminación, pero actualmente no existe un consenso al respecto de cuál es el mejor antiséptico: el alcohol posee un potente efecto bactericida inmediato y existe cierta evidencia científica a favor de la superioridad de la combinación de clorhexidina y alcohol, pero la mayoría de los estudios son heterogéneos y con resultados poco concluyentes. Algunos autores sugieren incluso que, con una técnica de extracción adecuada por parte de personal debidamente formado, el antiséptico elegido es poco relevante en la tasa de contaminación de hemocultivos


Blood cultures are the gold standard for the etiological diagnosis of bacteremia, though false-positive results are relatively frequent primarily due to contamination from skin flora during sample extraction. Correct skin antisepsis is important for reducing the bacterial load and opportunities for contamination. However, there is currently no solid consensus on the best antiseptic method. Alcohol has a potent immediate bactericidal effect, and there is some scientific evidence in favor of its combination with chlorhexidine, but most studies on this issue are heterogeneous and with inconclusive results. Some authors even suggest that the chosen antiseptic is irrelevant to the contamination rate, provided the blood culture extraction method is adequate and is performed by a trained professional

RESUMO

La antisepsia cutánea en los procedimientos invasivos tiene como objetivo disminuir la carga bacteriana en el lugar de la incisión o punción. Las soluciones alcohólicas parecen ser más eficaces en la prevención de la infección del sitio quirúrgico. Desde el punto de vista de la seguridad existe el potencial riesgo de ignición cuando se utilizan soluciones alcohólicas. Dada la potencial neurotoxicidad del alcohol y del gluconato de clorhexidina, debe evitarse el contacto de las soluciones antisépticas con el sistema nervioso central


Skin antisepsis in invasive procedures aims to reduce the bacterial load at the site of incision or puncture. Alcohol solutions seem to be more effective in preventing surgical site infection. From the safety point of view there is the potential risk of ignition when using alcohol solutions. Given the potential neurotoxicity of alcohol and chlorhexidine gluconate, contact of antiseptic solutions with the central nervous system should be avoided

RESUMO

Se ha propuesto la aplicación de diferentes medidas relacionadas con la asepsia para la prevención de bacteriemia relacionada con catéter endovascular. Entre estas medidas de asepsia recomendadas por diferentes sociedades científicas se encuentra la higiene de manos de la persona que canaliza o manipula el catéter, la aplicación de unas máximas medidas de barrera durante la canalización del catéter, la desinfección de las llaves de 3pasos y los puntos de inyección, la no utilización de cremas antibióticas (salvo en los catéteres de hemodiálisis), el cambio del apósito si se encuentra manchado, húmedo o despegado, y el uso de una técnica aséptica durante el cambio de apósito. Otras medidas recomendadas solo en las pautas publicadas más recientemente (es posible que por la publicación de recientes estudios que objetivan su efecto beneficioso) son la utilización de apósitos impregnados en antimicrobianos, el cambio de apósitos transparentes cada 7 días y los baños del paciente con clorhexidina


Several measures related to asepsis for preventing catheter-related bloodstream infection have been proposed. The aseptic measures recommended by scientific societies include hand hygiene of the person who is inserting or manipulating the catheter; maximum sterile barrier precautions during catheter insertion; disinfection of catheter hubs; the use of needle-less connectors and injection ports; the avoidance of antibiotic ointments (except in hemodialysis catheters); change the dressing if it is soiled, loose or damp; and aseptic technique during dressing changes. Other measures only recommended by the most recently published guides (possibly due to the publication of recent studies reporting their beneficial effects) are the use of antimicrobial-impregnated dressings, changing transparent dressings every 7 days, and bathing of the patient with chlorhexidine

RESUMO

Los conectores sin aguja proporcionan puntos de acceso fácil al sistema vascular para la administración de fluidos, evitando riesgos de punción accidental y aumentando la seguridad en la manipulación del acceso vascular. Una manipulación no aséptica puede favorecer su contaminación, convirtiéndolos en puerta de entrada de contaminantes endoluminales con capacidad de desencadenar complicaciones infecciosas de graves consecuencias para el paciente. ave y evitable, es necesario incluir en los programas de prevención aquellas medidas que eviten factores predisponentes como serían el aumento de la capacitación del personal, el diseño seguro de los dispositivos, la mejora del procedimiento de desinfección y el uso óptimo del antiséptico. Monitorizar la aplicación de prácticas seguras y difundir los resultados es importante para promover la comprensión de riesgos y beneficios que comporta la descontaminación de las conexiones y mejorar así la seguridad de los pacientes


Needleless connectors provide easy access points to the vascular system for the administration of fluids, avoiding the risk of accidental punctures and increasing safety in vascular access manipulation. Non-aseptic manipulation can favor contamination, turning connectors into the penetration route for endoluminal contaminants with the capacity of triggering infectious complications, with serious consequences for the patient. Considering catheter-related bacteremia as a serious and avoidable adverse effect, prevention programs should incorporate measures to combat predisposing factors, such as improved staff training, the safe design of devices, improved disinfection procedures, and optimized antiseptic use. Monitoring adherence to safe practices and reporting results are important to promote understanding of the risks and benefits of decontaminating connections and thus to improve patient safety

RESUMO

La infección del tracto urinario asociada al catéter es muy común tanto en el entorno hospitalario comunitario como en el de agudos, especialmente en el ámbito de cuidados intensivos. Para minimizar este problema es esencial realizar un abordaje correcto desde la inserción del catéter urinario hasta la extracción del mismo y aplicar siempre medidas antisépticas adecuadas. Hay demasiada información sobre las medidas antisépticas sin resultados consistentes. Este artículo tiene como objetivo revisar la evidencia científica existente sobre el tema y hacer recomendaciones basadas en la evidencia, a fin de optimizar los resultados. Todo el proceso se complementa con algunas consideraciones para lograr un manejo adecuado del catéter urinario del paciente


Catheter-related urinary tract infections are very common both in the community and in the acute hospital care setting, particularly in the critical care environment. In order to minimize this problem, it is essential to adopt a correct approach from insertion to withdrawal of the urinary catheter, and always perform proper antisepsis. There is too much information on antisepsis measures with no consistent results. The present article reviews the existing scientific evidence on the subject and establishes recommendations based on the evidence, in order to optimize outcomes. The entire process is complemented with considerations on how to secure proper management of the indwelling urinary catheter

RESUMO

INTRODUCTION: Surgical site infection is associated with significant morbidity and mortality. Effective preoperative skin decolonisation is an important preventative strategy. The National Institute for Health and Care Excellence clinical guidelines recommend decolonisation using chlorhexidine gluconate (CHG) or povidone iodine (PVI). Current evidence indicates that CHG is more effective, while the combination of CHG and PVI is greater still. This study describes current practice among neurosurgeons in the UK, including differences between trainees and consultants, to review compliance with the latest evidence. MATERIALS AND METHODS: A Society of British Neurosurgical Surgeons approved national, multicentre questionnaire was circulated online. A total of 74 complete responses were obtained from 27 trainees and 47 consultants, representing 28 of 37 neurosurgical centres. RESULTS: Of the total responding centres, 36 (49%) used a single agent and 38 (51%) used a dual-agent preparation. One respondent used Tisept®. Seventy (95%) used alcohol in some form and none used aqueous CHG. Trainees were more likely to use a dual-agent preparation (P = 0.025). Forty-seven (63%) prepared the skin three or more times, with trainees preparing the skin more times than consultants (P = 0.002). CONCLUSION: Neurosurgical practice adheres to national clinical guidelines but not the latest evidence from the literature. Given the weighting placed on randomised controlled trials, such a trial may be required to standardise practice that is likely to reduce surgical site infection.

RESUMO

Surgical site infection (SSI) is the third most frequent healthcare-associated infection in France. SSI rates in total hip or knee replacement are around 2%. The main bacteria implicated in SSI in clean surgery are those of the skin flora, whence the importance of skin preparation to eliminate transient flora and reduce resident flora. Guidelines for the prevention of SSI have progressed in recent years in France: firstly in 2013, and then in 2016. That preoperative hair removal and scrubbing of clean skin ahead of cutaneous asepsis is non-contributive was confirmed in 2013. A shower with normal soap taken as close to the beginning of surgery as possible is still recommended, as is use of alcoholic antiseptics for cutaneous asepsis. The debate remains open between chlorhexidine and povidone-iodine in several surgical specialties in the absence of any multicenter studies. Future choices of antiseptic may need to take account of resistance, especially to chlorhexidine, and possible side-effects. Finally, antimicrobial skin sealants and adhesive surgical drapes are not recommended for the prevention of infection.
