Does exposure to polymethyl methacrylate bone cement increase the risk of surgical glove failure?

INTRODUCTION: Surgical glove perforation has been linked to a double-fold increased risk of surgical site infection. Infection in the context of arthroplasty can have devastating consequences. In orthopaedics, use of polymethyl methacrylate (PMMA) bone cement is commonplace, and the impact on glove strength and perforation risk is not fully understood. This study aimed to examine the resistance to perforation and thickness of gloves following PMMA exposure, in accordance with the International Organization for Standardization (ISO) standard for glove integrity. METHODS: Pairs of gloves were separated and randomly sorted into exposure and control groups. Twenty pairs of latex and 40 pairs of polyisoprene gloves were used. Exposure group glove cuffs were in contact with cement from a single surface of the glove for 13 min as cement cured. Force to perforation and glove thickness were tested in accordance with ISO guidelines. RESULTS: Latex gloves were found to have a significantly increased force to perforation following PMMA exposure (10.26 Newtons (N) vs. 9.81 N, P = 0.048). Both polyisoprene under- and over-gloves were shown to have no significant change in strength to perforation post exposure (9.69 N vs. 9.83 N, P = 0.561, and 10.26 N vs. 10.65 N, P = 0.168, respectively). All groups were over the ISO standard minimum strength of 5 N. CONCLUSIONS: Exposure of latex and polyisoprene surgical gloves to PMMA bone cement does not appear to increase glove perforation risk and rather may improve natural rubber latex glove strength. This study supports the use of latex and polyisoprene surgical gloves in procedures that involve the handling of PMMA bone cement.

Compression therapy using surgical gloves is ineffective for the prevention of vincristine-induced neuropathy in patients with malignant lymphoma.

PURPOSE: Vincristine (VCR) often induces peripheral neuropathy (PN) as an adverse event. Currently, there is no consensus on the prevention of vincristine-induced PN (VIPN). In this study, we aimed to investigate the efficacy of compression therapy using surgical gloves for preventing VIPN. METHODS: Patients with malignant lymphoma (vincristine-naïve) who were receiving chemotherapy with cyclophosphamide, doxorubicin, VCR, and prednisolone, with or without rituximab, every 3 weeks for six cycles were eligible. For every VCR infusion, each patient wore two one-size-smaller gloves on one hand (study hand) for 90 min. The other hand was left bare (control hand). PN was assessed at each treatment using the Common Terminology Criteria for Adverse Events ver. 4.0. RESULTS: Fifty-one patients with malignant lymphoma were enrolled and 44 were evaluated. At 1 month after treatment, the occurrence rates of grade ≥ 2 sensory PN were 13.6 and 13.6% in the study and control hands, respectively (p = 1.0), and those of grade ≥ 2 motor PN were 15.9 and 15.9% in the study and control hands, respectively (p = 1.0). CONCLUSION: Compression therapy using surgical gloves showed no significant effect for the prevention of VIPN.

Gloves Contamination During Revision Surgery for Periprosthetic Joint Infection.

BACKGROUND: The use of double gloving has become a standard practice for joint replacement surgeons. However, since there are limited data on how gloves are contaminated during both primary and revision arthroplasty, no precise protocol exists to direct surgeons on when, or if, to change their gloves. The goals of this preliminary study were to evaluate the contamination of gloves during total joint arthroplasties (TJAs). METHODS: We included 25 infected cases and 10 primaries, which were performed at the same institution using the same surgical protocol from 3 fellowship trained surgeons. Samples were taken every 20 minutes from the start of the surgery until the joint was irrigated. Procedural steps were noted. To evaluate cross-contamination during infected cases, we sampled gloves using blood agar plates. In primary cases, culture swabs of anterior chamfer cuts and sterile instruments on the back table were used as negative controls. Next-generation sequencing (NGS) was used as an adjunct to identify low virulence bacteria. RESULTS: In the primary cases, all samples were found culture negative but 3 (8.1%) of the 37 samples were found to have a low, unidentifiable bacterial mass via NGS testing. In the infected cases, 41 (59.4%) of the 69 samples yielded positive microbial results. The positivity rate was higher in the samples collected after the arthrotomy was performed (70%) compared to samples collected before the arthrotomy was performed (40%), and the surgeon was only dissecting superficial layers (P = .502). CONCLUSION: Gloves seem to be a common source of cross-contamination in the intraoperative field during revision TJA. Due to the higher percent of positive samples following the opening of the joint, we hypothesize that the arthrotomy allows for the spread of bacteria across the operative site. While further investigation is necessary to formulate a precise protocol for the changing of gloves during TJA, it may be beneficial to perform a thorough irrigation of the joint and change of the gloves immediately following arthrotomy.

Sterile vs Nonsterile Gloves for the Repair of Wounds and Lacerations: A Systematic Review and Meta-Analysis.

This systematic review and meta-analysis discusses use of sterile vs nonsterile gloves for the repair of wounds and lacerations.

A Deep Learning Approach to Classify Surgical Skill in Microsurgery Using Force Data from a Novel Sensorised Surgical Glove.

Microsurgery serves as the foundation for numerous operative procedures. Given its highly technical nature, the assessment of surgical skill becomes an essential component of clinical practice and microsurgery education. The interaction forces between surgical tools and tissues play a pivotal role in surgical success, making them a valuable indicator of surgical skill. In this study, we employ six distinct deep learning architectures (LSTM, GRU, Bi-LSTM, CLDNN, TCN, Transformer) specifically designed for the classification of surgical skill levels. We use force data obtained from a novel sensorized surgical glove utilized during a microsurgical task. To enhance the performance of our models, we propose six data augmentation techniques. The proposed frameworks are accompanied by a comprehensive analysis, both quantitative and qualitative, including experiments conducted with two cross-validation schemes and interpretable visualizations of the network's decision-making process. Our experimental results show that CLDNN and TCN are the top-performing models, achieving impressive accuracy rates of 96.16% and 97.45%, respectively. This not only underscores the effectiveness of our proposed architectures, but also serves as compelling evidence that the force data obtained through the sensorized surgical glove contains valuable information regarding surgical skill.

Application of Field Sterility to Safely Reduce Cost and Waste in Cleft Surgery.

BACKGROUND: Healthcare spending in the United States remains a major concern, requiring reforms to control spending and curtail costs. Medical supply is one of the largest expenses for hospitals and strategies should be utilized to reduce nonbeneficial service delivery, which increases cost without concomitant increase in value. Introduction of field sterility is one of the potential strategies that has been applied in several surgical disciplines to improve cost-efficiency by reducing overuse of resources and decreasing enormous medical waste. Of course, this must be applied without a diminution in safety. METHODS: The PubMed, Medline, and Cochrane databases from 1980 to 2022 were used to review literature. Key words included "cleft surgery and field sterility," "sterile gloves and oral surgery," "oral surgery and field sterility," "sterile techniques and cleft palate surgery," "sterile versus nonsterile gloves," "sterile and non-sterile gloves and minor surgery," "skin laceration repair and sterile techniques," "sterile gloves and wound suture," "surgical site infection and field sterility," "operating room versus clinical setting," "operating rooms economics and hand surgery," and "main operating room versus ambulatory." RESULTS: The literature search yielded 827 articles. Following evaluation of titles, abstracts, and manuscript contents, 23 articles were ultimately included, of which 10 discussed field sterility and cost-efficiency for cutaneous procedures, 9 hand surgery, and 4 oral surgery. There was no study evaluating field sterility application in cleft surgery. In the reviewed studies, no statistical significance was observed in surgical site infection (SSI) with substantial cost savings and medical waste reduction when hand procedures were performed in ambulatory settings with field sterility compared to the main operating room (OR). Furthermore, no difference was observed for SSI in wound closure, excision of skin lesions, or Mohs micrographic surgery when nonsterile gloves were used. CONCLUSION: The incidence of infection following most cleft-related procedures remains low. As such, the application of field sterility may be ideal for this setting. The cost and waste associated with standard operating protocols are not warranted for many cleft procedures.

A randomized controlled trial using surgical gloves to prevent chemotherapy-induced peripheral neuropathy by paclitaxel in breast cancer patients (AIUR trial).

BACKGROUND: Chemotherapy-induced peripheral neuropathy (CIPN) is a common adverse effect of taxane treatment and can significantly affect patient quality of life. Currently, there are no effective treatments to alleviate symptoms of CIPN; thus, starting with prevention steps in high-risk patients is considered advantageous. However, for these prevention steps to be applicable to all patients, their side effects or accompanying discomforts should be minimal, and the intervention cost-effective. Compression therapy can be considered a prevention intervention, and using surgical gloves is feasible and cost-effective (approximately $0.6 per pair). Although previous studies on compression therapy using surgical gloves have reported decreased incidence of PN, these studies were non-randomized, limited to nab-paclitaxel treatment, and involved the use of small gloves, which may have caused discomfort. Therefore, this study aimed to assess the preventive effects of compression therapy using normal-sized surgical gloves on CIPN in patients treated with paclitaxel. METHODS: This clinical trial is designed to evaluate the preventive effects of compression therapy using surgical gloves on CIPN in women with stage II-III breast cancer who received paclitaxel chemotherapy for at least 12 weeks. This multicenter, randomized-controlled, open-label study will be conducted in six academic hospitals. Patients with medication or a medical history related to neuropathy or hand disease will be excluded. The primary outcome will be the preventive effect of compression therapy using surgical gloves, measured based on changes in the neurotoxicity component of the Functional Assessment of Cancer Therapy-Taxane questionnaire. Furthermore, we will assess the National Cancer Institute's Common Terminology Criteria for Adverse Events grade of CIPN after 6 months. Notably, the estimated sample size, based on a p-value < 0.025 and statistical power of 0.9, will consist of 104 patients (52 per group), accounting for a 10% sample loss. DISCUSSION: This intervention can be easily implemented in clinical practice and may serve as a preventive strategy for CIPNs with strong patient adherence. If successful, this intervention could improve the quality of life and treatment adherence in patients receiving chemotherapy that can induce PN, extending beyond paclitaxel treatment alone.

Higienização de mãos e uso de luvas: Gestão de Práticas de Enfermagem / Hand hygiene and glove use: Nursing Practice Management

As Infeções Associadas aos Cuidados de Saúde são consideradas um problema grave à escala mundial, sendo alvo de atenção especial por parte da Organização Mundial de Saúde e a Direção-Geral da Saúde. Ao longo dos anos, estas organizações têm promovido diversas iniciativas para minimizar e erradicar este problema. A higiene das mãos e o uso de luvas têm se evidenciado, como das medidas mais acessíveis e eficientes para combater esta problemática. No entanto, a adesão a estas boas práticas continua a estar longe do desejado. Esta investigação foi realizada numa instituição de saúde da região centro de Portugal, através de um estudo sobre as práticas de enfermeiros relacionadas com a higienização das mãos e uso de luvas. Enveredou-se pela realização de um estudo com características mistas (metodologia quantitativa e qualitativa). Foram estabelecidos como objetivos do estudo: identificar as barreiras à higienização das mãos percecionadas pelos enfermeiros; identificar práticas dos enfermeiros relativamente ao uso das luvas e conhecer estratégias utilizadas pelos enfermeiros gestores para promover a adesão à higienização das mãos e uso de luvas. Os resultados permitiram identificar como principais barreiras à HM, aspetos da responsabilidade da área da gestão, ?Liderança & Alertas Formais? e ?Avaliação & Feedback?. Deste modo, os enfermeiros destacam a importância do papel desempenhado pelas chefias na motivação para a mudança de comportamentos, através de trabalho em equipa e boas relações entre os profissionais de saúde. Verificou-se que a maioria dos enfermeiros detém conhecimentos sobre o uso correto de luvas e que os enfermeiros gestores, criam estratégias como por exemplo divulgação de cartazes e ações de sensibilização, para promover a adesão à higienização das mãos e uso de luvas. Concluímos que existe a necessidade de aumentar a formação em serviço neste âmbito, criar estratégias para colmatar as lacunas a nível de recursos materiais, reforçar a cultura de segurança através da notificação de erros e valorizar o papel do enfermeiro gestor na prevenção e controlo de IACS.

A critical review on the current state of antimicrobial glove technologies: advances, challenges and future prospects.

Following recent viral outbreaks, there has been a significant increase in global demand for gloves. Biomedical research focuses increasingly on antimicrobial gloves to combat microbial transmission and hospital-acquired infections. Most antimicrobial gloves are manufactured using antimicrobial chemicals such as disinfectants, biocides and sanitizers. The design of antimicrobial gloves incorporates advanced technologies, including colloidal particles and nanomaterials, to enhance antimicrobial effectiveness. A category of antimicrobial gloves also explores and integrates natural antimicrobial benefits from animals, plants and micro-organisms. Many types of antimicrobial agents are available; however, it is crucial that the selected agent exhibits a broad spectrum of activity and is not susceptible to promoting resistance. Additionally, future research should focus on the potential effect of antimicrobial gloves on the skin microbiota and irritation during extended wear. Careful integration of the antimicrobial agent is essential to ensure optimal effectiveness without compromising the mechanical properties of the gloves.

No Link Between Inadvertent Surgical Glove Contamination and Surgical Site Infection in Patients Undergoing Elective Neurosurgical Operations.

INTRODUCTION: Controllable factors associated with surgical site infections (SSIs) have focused on reducing contamination of the surgical field with potential pathogens. The aim of this prospective study is to determine the incidence of glove contamination in a series of elective neurosurgical operations and determine the relationship of such glove contamination to subsequent SSI. We hypothesize that contamination of surgical gloves is associated with subsequent SSI. METHODS: In this prospective quality improvement study, gloves of the surgical team were swabbed for standard culture just prior to wound closure of elective neurosurgical operations. Patient characteristics, surgical details, and occurrence of subsequent SSIs were collected retrospectively from the electronic medical records. Data were analyzed with χ2 with Fisher's exact test and Student's t test. RESULTS: Surgical glove contamination occurred in 10 of 96 elective neurosurgical cases (10.4%). SSIs occurred in 6 cases (6.2%), but no SSI occurred in a case in which surgical glove contamination occurred (P = 1). SSI was associated with younger patient age (P = 0.0448), and surgical glove contamination was associated with less resident experience (P = 0.0354). CONCLUSIONS: Surgical glove contamination identified at the time of wound closure does not correlate with the development of subsequent SSI in elective neurosurgical operations.

Influence of closed glove exchange on bacterial contamination of the hands of the surgical team.

OBJECTIVE: To determine if closed glove exchange (CGE) increases hand contamination. STUDY DESIGN: Prospective experimental study. SAMPLE POPULATION: Surgical teams participating in 65 individual surgical procedures were included, resulting in 200 individual enrollments. METHODS: At the completion of surgery, gloves were removed and hands were swabbed. The inside of the gown cuff was swabbed. Each participant regloved, using a closed gloving technique. The new gloves were removed, and hands were swabbed for culture a second time. Swabs underwent standard bacterial culture. RESULTS: Before glove exchange, or baseline, contamination was found on 17/200 dominant hands and 13/200 nondominant hands. After performing CGE, contamination was found on 14/200 and 15/200 dominant and nondominant hands, respectively. No difference was detected between the number of CFUs cultured from a surgeon's hands before CGE and the number of CFUs cultured from a surgeon's hands post-CGE (one sided sign test, p = .61). Twelve (12) different bacterial species were identified, the most common were Staphylococcus spp. (97/154; 63%). CONCLUSION: Closed glove exchange did not increase bacterial hand contamination over baseline levels. CLINICAL SIGNIFICANCE: We found no evidence to support discontinuing CGE.

Large hospital-wide outbreak of Paenibacillus spp pseudobacteremia associated with contaminated nonsterile gloves.

We report a large, hospital-wide outbreak of pseudobacteremia by Paenibacillus spp. In total, 139 patients presented at least 1 positive blood culture during a 13-month period. Microbiological experiments indicated that contaminated nonsterile gloves were associated with the pseudobacteremia episodes. The outbreak was resolved by discontinuing the use of the involved brand.

Evaluation of fluid leakage at the coverall and glove interface in single and double glove conditions.

BACKGROUND: Fluid leakage through the glove-protective clothing interface is an area of concern for many health care personnel, including emergency medical service providers, who may wear coveralls to protect themselves from multiple types of hazards. There is currently no established standard test method to specifically evaluate the barrier performance of the glove-protective clothing interface region for any personal protective equipment ensemble. OBJECTIVE: This study quantifies the fluid leakage at the coverall and glove interface using single and double gloving. METHODS: A robotic arm, which can simulate upper extremity movements of health care personnel, was used to test 5 coverall models and an extended examination glove model in single and double glove conditions. RESULTS: The results show that there was a significant difference in fluid leakage amounts between some of the coverall models and the number of glove layers studied. Findings also highlight that there is a high correlation between basis weight and stiffness of the coverall fabrics and the fluid leakage amounts. CONCLUSIONS: These results underline that coverall constructed from thin and less stiff fabrics can result in lower fluid leakage levels. Also, there was no significant difference in fluid leakage amounts between single and double gloves when tested with each of the coverall models, with the exception of the coveralls with the highest basis weight and stiffness.
