Impact of replacing powdered gloves with powder-free gloves on hand-hygiene compliance among healthcare workers of an intensive care unit: a quasi-experimental study

Background/objectiveAfter wearing powdered gloves, healthcare workers (HCW) are supposed to wash their hands instead of using alcohol-based hand-rub (ABHR). Washing hands takes longer than using ABHR, and the use of powdered gloves may be an obstacle to hand-hygiene compliance. This study aimed to evaluate the impact of replacing powdered gloves with powder-free gloves on hand-hygiene compliance among HCW of an intensive care unit (ICU).MethodsA quasi-experimental study was conducted in a general ICU of a tertiary care university hospital in Brazil. From June 1st to July 15th, 2017, all HCW were provided with powdered latex gloves only for all clinical procedures. From July 15th to August 31st, 2017, HCW were provided with nitrile powder-free gloves only. Hand-hygiene compliance was assessed through direct observation, and evaluated according to the World Health Organization Hand Hygiene guidelines. We calculated that a sample size of 544 hand hygiene opportunities needed to be observed per period. Data analysis were performed using the STATA SE® version 14, and we compared the individual’s percentage of compliance using the t test for paired data before and after the intervention.ResultsOverall, 40 HCW were assessed before and after the introduction of nitrile powder-free gloves, with 1114 and 1139 observations of hand hygiene opportunities, respectively. The proportion of compliance with hand hygiene was 55% (95% confidence interval [CI] 51–59%) using powdered latex gloves and 60% (95% CI 57–63%) using powder-free gloves. The difference in proportions between the two types of gloves was 5.1% (95% CI 2.5–7.6%, p < 0.001).ConclusionOur data indicate that replacing powdered gloves with powder-free gloves positively influenced hand-hygiene compliance by HCW in an ICU setting.

Computer vision based medical waste separator

In this study we have aimed to build an automatic computer vision based medical waste separator that detects the presence of medical waste and categorizes them into one of the four categories namely gloves, mask, syringe and cotton. This embedded system uses transfer learning on the AlexNet deep learning network to train a model which classifies medical waste. The hardware set up is designed to detect the movement of the lid of the input bin and then capture an image of the waste object dropped into the bin. This image is then fed to our trained model which classifies the object with a 86.17\% validation accuracy. Once the model classifies it, the waste object is dropped into the correct bin with the help of servo motors. This embedded system has been tested with different types of gloves, mask, syringe and cotton samples and presents a convenient way to segregate medical waste successfully. Thus this system aims to eliminate the need for manual labour to segregate hazardous medical waste and avoids harmful exposure to contaminated waste.

Development of a simple method for determination of gas permeability resistance of whole chemical protective gloves

Objectives: We investigated the protection performance of whole gloves by developing a straightforward permeability resistance method and evaluating the permeation over 480 min. Methods: The permeation time for toluene was obtained for seven glove types according to the Japanese Industrial Standards. In addition, the permeability resistance of whole gloves was evaluated from the ratio of collected amount of toluene in the passive layered sampler attached to the inside and outside of the glove. Results: The permeation times of the two types of polyurethane gloves evaluated were less than 1 min each. However, the percentages of toluene that permeated through the whole gloves determined by the developed method were 32.5% and 6.8% for the thin and thick gloves, respectively, at 480 min and 71.8% and 24.1% for the thin and thick gloves, respectively, at 1,440 min. Permeation times for all three types of layered films were more than 1,440 min, but the whole glove tests showed differences of 1.7%, 3.1%, and less than 0.1% at 1,440 min. The causes of these differences were assumed to be related to variations in thickness, type of material, and differences in deposition state of the various gloves. Conclusions: It became possible to grasp the permeation performance throughout whole chemical resistant gloves, which could not be known only with material testing, using a straightforward permeability test method.

Vision based 3D Gesture Tracking using Augmented Reality and Virtual Reality for Improved Learning Applications

3D gesture recognition and tracking based augmented reality and virtual reality have become a big interest of research because of advanced technology in smartphones. By interacting with 3D objects in augmented reality and virtual reality, users get better understanding of the subject matter where there have been requirements of customized hardware support and overall experimental performance needs to be satisfactory. This research investigates currently various vision based 3D gestural architectures for augmented reality and virtual reality. The core goal of this research is to present analysis on methods, frameworks followed by experimental performance on recognition and tracking of hand gestures and interaction with virtual objects in smartphones. This research categorized experimental evaluation for existing methods in three categories, i.e. hardware requirement, documentation before actual experiment and datasets. These categories are expected to ensure robust validation for practical usage of 3D gesture tracking based on augmented reality and virtual reality. Hardware set up includes types of gloves, fingerprint and types of sensors. Documentation includes classroom setup manuals, questionaries, recordings for improvement and stress test application. Last part of experimental section includes usage of various datasets by existing research. The overall comprehensive illustration of various methods, frameworks and experimental aspects can significantly contribute to 3D gesture recognition and tracking based augmented reality and virtual reality.

To glove or not to glove? Investigations into the potential contamination from handling of paper-based cultural heritage through forensic fingerprinting approaches

The handling of cultural heritage objects has become a highly debated topic in the last decade. The work and outcomes described in this paper are aimed to provide objective data to assist in making appropriate decisions as to whether or not wearing gloves is appropriate in a given situation. The forensic fingermark development techniques of 1,2-indandione and single metal deposition II were used to investigate the efficacy of handwashing and glove use to improve the information available when deciding whether to use gloves when handling paper objects. It was found that fingermarks did not permeate through polymer glove types but could through cotton gloves. It was also shown that the amounts of observable fingermark residues were greater 5 min after handwashing than if handwashing had not occurred, undermining previous arguments for not wearing gloves if hands could be washed before object handling.

A Method for Analyzing the Effectiveness of Vibration-Reducing Gloves Based on Vibration Power Absorption

The effectiveness of vibration-reducing (VR) gloves is conventionally assessed based on the vibration transmissibility of the gloves. This study proposed a method for analyzing and assessing the effectiveness of VR gloves based on how gloves affect the vibration power absorption (VPA) of the hand–arm system and its distribution. A model of the entire tool–handle–glove–hand–arm system was used to predict the VPA distributed in the glove and across the substructures of the hand–arm system. The ratio of the gloved-VPA and ungloved-VPA in each group of system substructures was calculated and used to quantify VR glove effectiveness, which was termed the VPA-based glove vibration transmissibility in this study. The VPA-based transmissibility values were compared with those determined using to-the-hand and on-the-hand methods. Three types of gloves (ordinary work glove, gel VR glove, and air bubble VR glove) were considered in the modeling analyses. This study made the following findings: the total VPA-based transmissibility spectrum exhibits some similarities with those determined using the other two methods; the VPA-based transmissibility for the wrist–forearm–elbow substructures is identical to that for the upper–arm–shoulder substructures in the model used in this study; each of them is equal to the square of the glove vibration transmissibility determined using the on-the-wrist method or on-the-upper-arm method; the other substructure-specific VPA-based transmissibility spectra exhibit some unique features; the effectiveness of a glove for reducing the overall VPA in the hand–arm system depends on the glove effectiveness for absorbing the vibration energy, which seems to be associated primarily with the glove cushioning materials; the glove may also help protect the fingers or hand by redistributing the VPA across the hand substructures; this redistribution seems to be primarily associated with the glove structural properties, especially the tightness of fit for the glove.

Can Medical-Grade Gloves Provide Protection after Repeated Disinfection?

The advent of the COVID-19 pandemic has generated an increased consumption of personal protective equipment (PPE), including gloves and masks, by healthcare workers and by the general public at a global scale. This has generated substantial shortage of these single-use and disposable PPEs that will end up as a landfill waste. Extending the life cycle of PPEs, such as gloves, by disinfecting treatments could help mitigate these concerns. However, the effect of various disinfection treatments on the functionality of gloves is unknown. In this study, six commonly used viral disinfection treatment methods (i.e., ultraviolet (UV) radiation, dry heat, steam, alcohol, chlorine compounds, and quaternary ammonium compounds) were evaluated for their effect on the performance attributes of two commonly used medical-grade gloves and nitrile and vinyl (latex) gloves. The barrier properties of both gloves against water and ethanol vapor flux were not affected up to 10 cycles of disinfection cycles. However, the increase in the disinfection cycle from 10 to 20 slightly reduced their barrier properties with minor variation in the type of disinfection and glove type. Infrared spectroscopy and microscopy investigations confirmed that both types of gloves could withstand up to 20 cycles of disinfection treatments with no observable change in the chemical structure and surface morphology of the disinfected surfaces, respectively. Lastly, tear property testing of the gloves indicated little to no change from the baseline after 20 cycles of treatment in both the nitrile and vinyl-based gloves. Overall, this study indicated that alcohol, UV, and heat treatment could be acceptable disinfection methods that allow the reuse of gloves up to 20 cycles. Such repeated disinfection of gloves not only reduces the strain on the supply of gloves but also decreases the postconsumer landfilled waste and environmental footprint of gloves.

Enhanced detection of glove leakages - prospective examination of using a dye-modified water test according to DIN ISO 2859 / EN 420

Background: Leakage in medical gloves poses a risk to patients and health care workers (HCW). In particular, surgical settings a high level of safety and reliability of the related barrier measures is mandatory. After a high leakage rate of 20% (16/84) was found in a previous random sample of 84 surgical gloves, the leakage rate was analyzed in a prospective study on surgical gloves from a operation room. For comparison, gloves that were used on a medical ward, were also tested. Methods and materials: Sterile surgical gloves (n = 154) from operations of the clinic for general and visceral surgery and nitrile gloves (n = 76) from a medical ward were collected. Gloves were recorded, and those with a primary defect or tearing before use (8/230) were discarded. Used gloves (n = 230) were sealed individually and examined by the water test according to ISO 2859/EN 420 with 1 l of water and then with 1 l methylene blue (1:10 V/V%). Duration of use, occupational profile, handedness of the user and localization of any leaks were recorded. Results: Twenty leaks were detectable on 17 gloves (leakage rate 7.7%). Surgeons and surgical assistants were affected by 15/20 leaks, multiple leaks only occurred in surgeons (n = 3). In gloves used at the ward, only two leaks were found. Leakage locations were palmar and index fingers (each n = 6) as well as the middle finger (n = 4). The dye test detected all leaks (18/18) on 15/15 leaking gloves, while the water test failed to detect 5/20 leaks on 2/17 gloves. Co-polymer gloves had a significantly higher risk (OR 15.5, 95% CI: 3.5–69.0, p = 0.001) for leakage than wearing any other type of gloves. Leakage rates for inner and outer gloves were equal (p > 0.50); the duration of use in the OP was positively associated (median 53 vs. 85 min., p = 0.051) with the occurrence of leakage, while on the ward there was no association. Conclusion: In our prospective study the high leakage rate was below 10%. Leakage occurs especially in areas with high mechanical stress (shear forces and frictional resistance). Adding color dye to the testing battery enhances the detection of leakages substantially.

Do surgeons use double gloves during surgery? Results of a survey.

&lt;b&gt;Introduction:&lt;/b&gt; The perforation of gloves during surgical procedures is quite common. A cheap and quite effective method of reducing the risk of blood-borne infections is wearing two pairs of gloves. Unfortunately, some surgeons are reluctant to it, and they report decreased dexterity and sensation. The aim of the study was to evaluate surgeons' double-gloving practices to determine the factors related to compliance. &lt;br&gt;&lt;b&gt;Material and methods:&lt;/b&gt; An anonymous, 21-question survey in Polish was sent by post to 41 surgical departments. The questions concerned: demographic data, type of surgical gloves used, allergy to latex, number of surgeries performed, frequency of using double gloves and negative impressions from using them and finally, the frequency of needlestick injuries during surgical procedures. &lt;br&gt;&lt;b&gt;Results:&lt;/b&gt; We received 179 questionnaires back. More than 62% of the surgeons believe that double gloves provide better protection than a single pair, 24% do not believe in this, and 14% have no opinion. Only 0.6% of respondents always use double gloves during surgery, 19% double glove in at least 25% of cases and 68% do it occasionally. 13% of the surgeons declared that they had never worn double gloves. During high-risk procedures, 86% of respondents wear double gloves. About half of respondents (50.3%) report discomfort while wearing double gloves; 45% - decreased dexterity; about 30% complain of numbness and tingling; and 64% - decreased sensation. &lt;br&gt;&lt;b&gt;Conclusion:&lt;/b&gt; Due to the high number of surgical glove perforations and relatively high prevalence of needlestick injuries, it is necessary to use methods that reduce the risk of transmission of pathogens. The habit of using a double pair of gloves should be implemented especially among young surgeons starting to train in their specialities. Consequently, the period of initial discomfort will be combined with the acquisition of surgical skills, which will allow for gradual acclimatization.

Endotoxin contamination of single-use sterile surgical gloves.

Aim: Strict endotoxin limits are enforced for implants and catheters inserted into the body. However, no standard limit has been set for single-use sterile surgical gloves. Materials & methods: Four types of gloves sold in Japan were dipped in saline and that endotoxin levels were measured. Cytokine producing activity of gloves in blood wasalso measured. Results: Three of the four types of gloves showed endotoxin contamination. We also confirmed an increase in cytokine production in these gloves except one glove in which anionic surfactants was found. Conclusion: The extent to which detected endotoxins enter the body during surgery is controversial, but strict endotoxin limits need to be established.

When Good Intentions Go Bad-False Positive Microplastic Detection Caused by Disposable Gloves.

Apart from being considered a potential threat to ecosystems and human health, the ubiquity of microplastics presents analytical challenges. There is a high risk of sample contamination during sampling, sample preparation, and analysis. In this study, the potential of sample contamination or misinterpretation due to substances associated with disposable laboratory gloves or reagents used during sample preparation was investigated. Leachates of 10 different types of disposable gloves were analyzed using Raman microspectroscopy (μ-Raman), Fourier-transform infrared microspectroscopy (μ-FTIR), and pyrolysis-gas chromatography/mass spectrometry (pyr-GC/MS). There appeared to be polyethylene (PE) in almost all investigated glove leachates and with all applied methods. Closer investigations revealed that the leachates contained long-chain compounds such as stearates or fatty acids, which were falsely identified as PE by the applied analytical methods. Sodium dodecyl sulfate, which is commonly applied in microplastic research during sample preparation, may also be mistaken for PE. Therefore, μ-Raman, μ-FTIR, and pyr-GC/MS were further tested for their capability to distinguish among PE, sodium dodecyl sulfate, and stearates. It became clear that stearates and sodium dodecyl sulfates can cause substantial overestimation of PE.

Surgical gloves' perforation rate and its associated factors in three Tunisian surgical departments

Abstract Background Surgical teams rely on gloves as a barrier that can prevent transmission of microorganisms from the practitioners to the patient and from patient to surgical team. However, holes and micro-perforations may occur in gloving material exposing both patients and surgical team members to several complications. This study aimed to investigate the gloves' perforation rate and the factors associated with glove defect. Methods It is descriptive cross-sectional study. It was spread over a period of 3 months (January-March 2017) and was conducted at the University Hospital of Sahloul-Sousse (Tunisia) in three different surgical departments (urology, maxillofacial and general and digestive surgery). A data collection sheet was used by the researchers to collect data about the intervention and the surgical teams such the type and the duration of the intervention and the type of gloves used by the surgical teams. The post-surgery gloves were collected and tested to detect perforations using the water-leak test as described in the European Norm “NF EN 455-1”. For percentage comparison, the chi-square test was used with a significance threshold of 5%. Results A total of 284 gloves were collected from 36 procedures. Of these, 47 were found to be perforated with a perforation rate of 16.5%. All perforations were unnoticed by the surgical team members. The majority of perforated gloves (61.7%) were collected after urology procedures (p = 0.00005), 77% of perforated gloves were detected when the duration of the procedure exceeded 90 minutes (p = 0.001), and 96% of gloves were from brand A, which were the thicker gloves (p = 0.015) Conclusions This study highlighted an important problem neglected by the surgical teams, despite the risks that it can generate and its potentially severe consequences. In light of this study, we recommend systematic double-gloving and frequent changing of gloves to prevent the gloves' perforation and reduce its risks. Key messages Surgical teams must be aware of the importance of the problem of gloves perforation. The findings reaffirm the importance of double-gloving and changing gloves in surgeries of more than 90 minutes duration.

Symptoms and Awareness of Latex Allergy Among Healthcare Workers

Objective: To evaluate the knowledge levels, sensitivity status, familial latex sensitivity, and attitudes towards the prevention and treatment of latex allergies of healthcare workers (HCWs) at a tertiary hospital. Materials and Methods: The study was carried out cross-sectionally between December 2012 and March 2013. A total of 566 HCWs at a tertiary hospital were included in the study. Results: The data of a total of 566 [333 (58.8%) female and 233 (41.2%) male] HCWs were analyzed. They consisted of 179 (31.6%) physicians, 48 (8.5%) technicians, 238 (42%) nurses, 48 (8.5%) laboratory technicians and 53 (9.4%) patient care workers. The family history of atopy was significantly higher in female HCWs (24.3%) compared to males (17.2%) (p= 0.041). A significant difference was identified between the occupational groups in terms of the rate of allergic symptoms after coming into contact with medical latex products (nurses 59.7%, doctors 17.6%, technicians 5.7%, laboratory technicians 6.9 %, patient care workers 10.1%; p= 0.001). Latexrelated symptoms were significantly more common in atopic HCWs (52.3%) compared to non-atopic ones (19.4%) (p= 0.001). The rate of latex-food syndrome was significantly more frequent in female HCWs (16%) compared to males (8.9%) (p= 0.038). Symptoms that developed after contact with medical and non-medical latex products were significantly more common in female HCWs (79.9% and 80.5%) compared to the male HCWs (21.1% and 19.5%) (p= 0.001). The rate of non-HCW(s) who shared the same house/room with the HCWs after work and who had allergic symptoms while in the same environment with the HCWs was 18%. The rate of these individuals was reported to be highest among the nurses at 53% and there was a statistically significant difference in terms of occupational groups (physicians 25.5%, technicians 9.8%, laboratory technicians 2.9%, patient care workers 7.8%; p= 0.030). Multivariate regression analysis showed that personal history of atopy (OR= 28.657, 95% CI= 6.548-125.411, p= 0.001) and the type of gloves used (latex gloves) (OR= 8.730, 95% CI= 3.490-21.834, p= 0.001) were independent predictors for latex allergy. Conclusion: In conclusion, latex is not only a cause of occupational allergy but is also an allergen that has the potential to cause allergic symptoms in people who share the same environment with HCWs. Questionnaires questioning the symptoms associated with past latex allergy may be an important tool for demonstrating latex sensitization in HCWs and managing latex-related reactions.

Do your surgical glove characteristics and wearing habits affect your tactile sensibility?

BackroundTactile sensibility plays a critical role in medicine, especially in surgical practice. In order to prevent surgical site infections and protect the surgeon, the use of surgical gloves is standard practice. However, wearing these might affect the sensibility of the hand disadvantageously, especially in disciplines that require precision work. MethodsWe evaluated the influence of six different glove types, as well as gloves wearing habits (double gloving, over- and undersized gloves) on tactile sensibility using two-point-discrimination and Semmes-Weinstein monofilament testing in 27 non-surgeons. ResultsThere were significant differences regarding tactile sensibility of gloved compared to bare hands and between different types of gloves. While undersized gloves and double gloving did not affect tactile sensibility, oversized gloves were associated with a significant deterioration of the sensibility of the hand in the Semmes-Weinstein monofilament test. ConclusionThis study demonstrates that surgical gloves negatively affect the sensibility of the hand and show significant differences between different types of gloves.

Fingermarks development on gloves: Relative efficiency of 1,2 Indanedione/ZnCl2, ninhydrin and wet powder

Powder suspensions such as wet powder are used to develop fingermarks on adhesive surfaces. They can also be used on gloves but these ready-to-use commercial pre-mixed solutions are not entirely satisfactory. Among other things, they generate some background noise that can sometimes be substantial and make the exploitation of the fingermarks difficult. Recent studies have proven the effectiveness of a HFE ninhydrin solution on some types of gloves. Ninhydrin and 1,2-indanedione are reagents that are commonly used for the visualisation of fingermarks on porous and semi-porous substrates. Applying them on gloves might help to overcome the issue of background noise being produced by powder suspensions. In this study, several formulations of ninhydrin and 1,2-indanedione are compared to wet powder on a sample of nitrile, latex and vinyl gloves. The subsequent results show a greater effectiveness with the use of wet powder.

Robotic Glove for Rehabilitation Purpose: Review

Rehabilitation robots have become one of the main technical instruments that Treat disorder patients in the biomedical engineering field. The robotic glove for the rehabilitation is basically made of specialized materials which can be designed to help the post-stroke patients. In this paper, a review of the different types of robotic glove for Rehabilitation have been discussed and summarized. This study reviews a different mechanical system of robotic gloves in previous years. The selected studies have been classified into four types according to the Mechanical Design: The first type is a tendon-driven robotic glove. The second type of robotic glove works with a soft actuator as a pneumatic which is operated by air pressure that passes through a plastic pipe, pressure valves, and air compressor. The third type is the exoskeleton robotic gloves this type consists of a wearable mechanical design that can used a finger-based sensor to measure grip strength or is used in interactive video applications. And the fourth type is the robotic glove with a liner actuator this type consists of a tape placed on the fingers and connected to linear actuators to open and close the fingers during the rehabilitation process.

Use of protective gloves by hairdressers: A review of efficacy and potential adverse effects.

Occupational hand eczema is common among hairdressers, and protective gloves are important in limiting exposure to irritants and allergens. Various glove types may differ in their protective ability, and their use may lead to hand eczema due to skin irritancy and allergy. MEDLINE was searched for studies investigating permeation of gloves to irritants and allergens used in the hairdressing trade, as well as adverse effects of glove use affecting hairdressers. Forty-four studies were identified; nine reported on permeation. Of those, two in vitro studies found nitrile rubber (NR) gloves to give the best protection when handling hair dyes. Polyethylene (PE) gloves had the lowest reported break-through time. The prevalence of sensitization to rubber materials in European hairdressers was as follows: thiuram mix, median 2.5% (range 0%-8.2%), weighted average 3.0% (95% confidence interval [CI] 3.0%-3.1%); mercapto mix, median 0.4% (range 0%-3.3%), weighted average 0.5% (95% CI 0.47%-0.50%), mercaptobenzothiazole, median 0.6% (range 0%-6.6%), weighted average 0.7% (95% CI 0.6%-0.7%), NRL-type I allergy, median 1.3% (range 1%-16.4%), weighted average 4.0% (95% CI 3.6%-4.5%). In conclusion, NR gloves provide the best skin protection for hairdressers, although natural rubber latex (NRL) and polyvinylchloride (PVC) gloves may be sufficient in most cases. PE gloves are not recommended. Synthetic rubber gloves with low or no levels of accelerators are preferred.

Double gloving of disposable nitrile gloves exposed to diethylene glycol mono-n-butyl ether

Double gloving of disposable gloves is now commonplace in healthcare settings when extra protection is needed against aqueous solutions and especially for antineoplastic drugs in isotonic aqueous media. In the present study, an ASTM F739 2.54 cm cell with closed-loop water collection without recirculation at 35 °C in a moving tray water bath was used to test the permeation of diethylene glycol mono-n-butyl ether (DGBE) through four types of disposable nitrile gloves that were singly and doubly layered in the permeation cell. Samples were taken over 8 hr for capillary gas chromatograph-mass spectrometer quantitation. The breakthrough time (tn) at a permeation of 250 ng/cm2 increased as thickness increased for single layers, but the steady-state permeation rates Ps in µg/cm2/min did not always decrease with increasing thickness. The double-layer tn, Ps and thickness were also more variable relative to a single layer. The thinnest glove with 80 m thickness showed a tn = 0–5 min whereas its double layer was 15–20 min. The thickest glove of 132 µm exhibited a tn = 10–15 min but its double layer was tn = 45–55 min. The adjusted double-layer average tn divided by the adjusted single-layer average tn was 4.0 ± 0.8. The adjusted average single-layer Ps divided by the adjusted average double-layer Ps was 3.5 ± 0.8. Other results showed that the average glove swelling was <10%; microscopic and leak testing indicated no penetration and reflectance infrared analysis also showed no chemical changes on the inside glove surfaces. Thus, the permeations were adjudged to obey Fick’s First Law of Diffusion to allow calculation of diffusion coefficients D in cm2/min. The average single-layer D divided by the average double-layer D was 1.3 ± 0.2. Double gloving in the field is therefore also probably more protective than single gloving against DGBE for the four types of disposable nitrile gloves tested.

Distributed vibration isolation and manual dexterity of anti-vibration gloves: is there a correlation?

This study focuses on the integrated performance of anti-vibration (AV) gloves in terms of manual dexterity and distributed palm and fingers’ vibration transmissibility. Experiments were designed to measure vibration transmission and manual dexterity performance of 10 different gloves using 15 subjects. The results showed all gloves impeded manual dexterity, while five gloves satisfied the AV glove screening criteria. Glove type yielded a significant effect on manual dexterity (p < 0.001) and vibration transmissibility (p ≤ 0.001). Manual dexterity decreased nearly linearly with an increase in glove thickness (p < 0.05), while palm and fingers’ vibration transmissibility in high-frequency range was negatively correlated with glove thickness (R2 > 0.70). A strong correlation was evident between glove material stiffness and the H-frequency range palm vibration transmissibility (R2 ≥ 0.8). While the vibration isolation of a glove is strongly related to material properties at the palm, the dexterity performance is dependent on design factors such as thickness and bulkiness. Practitioner summaryAnti-vibration gloves are used to isolate hand from power tools vibration, while these may adversely affect manual dexterity. Vibration isolation was correlated with material properties and thickness, while dexterity was correlated with thickness alone. Glove thickness is a vital parameter for realising a compromise between vibration isolation and manual dexterity.

Impact of Personal Protective Equipment on the Performance of Emergency Pediatric Tasks.

Personal protective equipment (PPE) is worn by health care providers (HCPs) to protect against hazardous exposures. Studies of HCPs performing critical resuscitation tasks in PPE have yielded mixed results and have not evaluated performance in care of children. We evaluated the impacts of PPE on timeliness or success of emergency procedures performed by pediatric HCPs. This prospective study was conducted at 2 tertiary children's hospitals. For session 1, HCPs (medical doctors and registered nurses) wore normal attire; for session 2, they wore full-shroud PPE garb with 2 glove types: Ebola level or chemical. During each session, they performed clinical tasks on a patient simulator: intubation, bag-valve mask ventilation, venous catheter (IV) placement, push-pull fluid bolus, and defibrillation. Differences in completion time per task were compared. There were no significant differences in medical doctor completion time across sessions. For registered nurses, there was a significant difference between baseline and PPE sessions for both defibrillation and IV placement tasks. Registered nurses were faster to defibrillate in Ebola PPE and slower when wearing chemical PPE (median difference, -3.5 vs 2 seconds, respectively; P < 0.01). Registered nurse IV placement took longer in Ebola and chemical PPE (5.5 vs 42 seconds, respectively; P < 0.01). After the PPE session, participants were significantly less likely to indicate that full-body PPE interfered with procedures, was claustrophobic, or slowed them down. Personal protective equipment did not affect procedure timeliness or success on a simulated child, with the exception of IV placement. Further study is needed to investigate PPE's impact on procedures performed in a clinical care context.
