Nitrile versus Latex for Glove Juice Sampling.

The objective of this study was to explore the utility of nitrile gloves as a replacement for latex surgical gloves in recovering bacteria from the hands. Two types of nitrile gloves were compared to latex gloves using the parallel streak method. Streaks of Klebsiella pneumoniae and Staphylococcus aureus were made on tryptic soy agar plates, and the zones of inhibition were measured around pieces of glove material placed on the plates. Latex gloves produced a mean zone of inhibition of 0.28 mm, compared to 0.002 mm for nitrile gloves (p<.001). While the parallel streak method is not intended as a quantitative estimate of antimicrobial properties, these results suggest that nitrile may be a viable alternative to latex in glove juice sampling methods, since nitrile avoids the risk of latex exposure.

Risk of Glove Perforation With Arthroscopic Knot Tying Using Different Surgical Gloves and High–Tensile Strength Sutures

To examine the risk of glove tears associated with arthroscopic knot tying using 4 commonly used high-tensile strength sutures and 2 different types of gloves. We analyzed 2 different surgical latex glove types (0.24-mm-thick powder-free and 0.32-mm-thick powdered) for perforation after arthroscopic knot tying with 4 different high-tensile strength sutures: Hi-Fi (ConMed Linvatec, Largo, FL), Ultrabraid (Smith & Nephew, Memphis, TN), FiberWire (Arthrex, Naples, FL), and Orthocord (DePuy Mitek, Raynham, MA). All knots were tied by a double-gloved single surgeon. Twelve trials of 4 knots each were performed for every glove-suture combination. All gloves were analyzed for perforation by a blinded evaluator using visual inspection, hydro-insufflation, and electroconductivity. The overall incidence of glove perforation was 3.4% and was detectable only by the electroconductivity method; the other 2 methods did not detect any perforations. There was a statistically significantly higher rate (P < .001) of perforations in the 0.32-mm powdered gloves (6.8%) compared with the 0.24-mm powder-free gloves (0%). Perforation of the inner glove occurred 5.7 times more frequently than perforation of the outer glove. However, simultaneous perforation of both the inner and outer gloves did not occur in any set. The Hi-Fi suture was involved in 6 perforations compared with 4 for FiberWire, 3 for Ultrabraid, and 0 for Orthocord. Double gloving provides an adequate surgical barrier between the surgeon and the patient during arthroscopic knot tying with high-tensile strength sutures as indicated by the low incidence of glove perforations in our study in an in vitro biomechanical evaluation. There were no instances of simultaneous perforation of both the inner and outer gloves. All perforations occurred only in the thicker (0.32-mm) powdered gloves. Glove tears and finger lacerations have been reported with the use of high-tensile strength sutures during arthroscopic shoulder surgery, thereby raising a concern for safety and disease transmission. This study addresses these concerns by evaluating the risk of glove tears during arthroscopic knot tying.

A Randomized Prospective Study of Glove Perforation in Orthopaedic Surgery: Is a Thick Glove More Effective?

We compared perforation rates among operative staff who were randomly assigned either thick latex surgical gloves or conventional gloves for use in performing total knee arthroplasty. A total of 1120 gloves were assessed in 70 total knee arthroplasties. Additionally, the degree of tactile sensitivity provided by the gloves was compared using a two-point discrimination (TPD) test. Perforation occurred in 27 surgeries (38.5%) and in 48 gloves (4.29%). Binary logistic regression analysis revealed that the operator was a risk factor for perforation rate (Odds ratio 14.448, P < .0.01) and that the type of glove was not (P = .896). In the TPD test, tactile sensitivity was lower for a thick outer glove than the conventional double glove (P < .001 for each site). Not only did thick surgical gloves lower tactile sensitivity, they also offered no superior protective effect over conventional gloves.

Wearing Ambidextrous Vinyl Gloves Does Not Impair Manual Dexterity

Universal precautions mandate that health care workers wear gloves to prevent the unintended spread of bloodborne pathogens. Gloves may affect manual dexterity, generally delaying task completion. Our previous study showed that wearing the wrong size latex surgical glove degraded manual dexterity. The use of non-sterile and non-latex gloves may limit certain risks and be more cost-effective. However, such gloves may produce different results. We hypothesized that ambidextrous vinyl examination gloves would degrade manual dexterity compared with bare hands. We studied 20 random subjects from a medical environment. Subjects performed a standard battery of Grooved Pegboard tasks while bare-handed, wearing ambidextrous non-sterile vinyl gloves that were their preferred size, a size too small, and a size too large. The order was randomized with a Latin Square design to minimize the effects of time, boredom, and fatigue on the subjects. Subjects were also invited to comment on the fit of different size gloves. Wearing vinyl gloves of both the preferred size and a size up or down failed to affect manual dexterity vs. bare hands on time to insert pegs, and pegs dropped during insertion or removal. In contrast, the time to remove pegs was reduced by wearing preferred size vinyl gloves compared with performing the task with bare hands (P < 0.05). Subjects reported a generally poor fit in all sizes. Vinyl gloves that were too small caused significant hand discomfort. Vinyl gloves surprisingly do not degrade manual dexterity even when worn in ill-fitting sizes. Wearing a preferred size vinyl glove vs. bare hands may improve dexterity in selected tasks. Choosing a comfortable, large size seems the best strategy when the preferred size is unavailable. Thinner vinyl gloves may improve grip and may not degrade touch as much as latex surgical gloves and may thus represent a reasonable choice for selected tasks.

Minimizing Surgical Skin Incision Scars with a Latex Surgical Glove

Minimizing Surgical Skin Incision Scars with a Latex Surgical Glove

Minimizing Surgical Skin Incision Scars with a Latex Surgical Glove

The current trend in minimally invasive surgery is to make a small surgical incision. However, the excessive tensile stress applied by the retractors to the skin surrounding the incision often results in a long wound healing time and extensive scarring. To minimize these types of wound problems, the authors evaluated a simple and cost-effective method to minimize surgical incision scars based on the use of a latex surgical glove. The tunnel-shaped part of a powder-free latex surgical glove was applied to the incision and the dissection plane. It was fixed to the full layer of the dissection plane with sutures. The glove on the skin surface then was sealed with Ioban (3 M Health Care, St. Paul, MN, USA) to prevent movement. The operation proceeded as usual, with the retractor running through the tunnel of the latex glove. It was possible to complete the operation without any disturbance of the visual field by the surgical glove, and the glove was neither torn nor separated by the retractors. The retractors caused traction and friction during the operation, but the extent of damage to the postoperative skin incision margin was remarkably less than when the operation was performed without a glove. This simple and cost-effective method is based on the use of a latex surgical glove to protect the surgical skin incision site and improve the appearance of the postoperative scar.

Human Coronaviruses: Insights into Environmental Resistance and Its Influence on the Development of New Antiseptic Strategies

The Coronaviridae family, an enveloped RNA virus family, and, more particularly, human coronaviruses (HCoV), were historically known to be responsible for a large portion of common colds and other upper respiratory tract infections. HCoV are now known to be involved in more serious respiratory diseases, i.e. bronchitis, bronchiolitis or pneumonia, especially in young children and neonates, elderly people and immunosuppressed patients. They have also been involved in nosocomial viral infections. In 2002–2003, the outbreak of severe acute respiratory syndrome (SARS), due to a newly discovered coronavirus, the SARS-associated coronavirus (SARS-CoV); led to a new awareness of the medical importance of the Coronaviridae family. This pathogen, responsible for an emerging disease in humans, with high risk of fatal outcome; underline the pressing need for new approaches to the management of the infection, and primarily to its prevention. Another interesting feature of coronaviruses is their potential environmental resistance, despite the accepted fragility of enveloped viruses. Indeed, several studies have described the ability of HCoVs (i.e. HCoV 229E, HCoV OC43 (also known as betacoronavirus 1), NL63, HKU1 or SARS-CoV) to survive in different environmental conditions (e.g. temperature and humidity), on different supports found in hospital settings such as aluminum, sterile sponges or latex surgical gloves or in biological fluids. Finally, taking into account the persisting lack of specific antiviral treatments (there is, in fact, no specific treatment available to fight coronaviruses infections), the Coronaviridae specificities (i.e. pathogenicity, potential environmental resistance) make them a challenging model for the development of efficient means of prevention, as an adapted antisepsis-disinfection, to prevent the environmental spread of such infective agents. This review will summarize current knowledge on the capacity of human coronaviruses to survive in the environment and the efficacy of well-known antiseptic-disinfectants against them, with particular focus on the development of new methodologies to evaluate the activity of new antiseptic-disinfectants on viruses.

An urgent necessity under general anaesthesia – surgical gloves made into re-breathing bag

Anaesthetic practice in resource-poor countries often requires a lot of improvisation on the part of practitioners in order to meet the needs of patients. Disposables in a low-resource environment are usually stretched beyond the manufacturer's recommended life span. While anaesthetizing a six-month-old baby with cleft lip, the reservoir bag was accidentally torn and was replaced with latex surgical gloves. In the absence of a spare bag this replacement served the patient throughout the period of surgery.

Disproportionated Rosin Dehydroabietic Acid in Neoprene Surgical Gloves

Allergic contact dermatitis (ACD) is a well-recognized immune-mediated disease often associated with the use of vulcanization accelerator-containing latex and nitrile gloves. Potential contact allergens in neoprene (polychloroisoprene, polychloroprene) gloves have not been reported. The objective was to analyze extracts of neoprene surgical and examination gloves for potential contact allergens. Four different brands of neoprene-type gloves were purchased, and dichloromethane extracts were derivatized and assayed by gas chromatographic mass spectrometry. A latex surgical glove was used as a negative control. Chemical species consistent with the composition of disproportionated rosin (dehydroabietic acid [DHA], didehydroabietic acid, and other pimaric or isopimaric species) were identified in dichloromethane extracts of neoprene gloves. Levels of DHA, a type IV prohapten that can be air oxidized to an active allergen, ranged from 7 to 31 mg/g of glove. A leaching study of DHA was conducted, and small amounts of DHA leached from the glove materials into artificial sweat. DHA oxidation products were not observed in any of the gloves assayed. DHA exposure may occur from neoprene-type glove use, although a potential association with glove ACD has not been established.

Anaphylaxis caused by latex surgical gloves immediately after starting surgery -A case report-

Anaphylaxis is an acute and fatal systemic allergic reaction to an allergen, and it can be an unpredictable and life-threatening cause during anesthesia. Latex is the second most common cause of anaphylaxis following the use of neuromuscular blocking agents during general anesthesia or surgery. We report on a 67-year-old male who had undergone surgery under general anesthesia without any problem but who presented with severe intraoperative anaphylaxis to latex surgical gloves. This case emphasizes the need for anesthesiologists to quickly diagnose and properly manage an allergic reaction in patients under general anesthesia.

Wearing the Wrong Size Latex Surgical Gloves Impairs Manual Dexterity

Universal precautions mandate that health care workers wear gloves when dealing with patients, often in situations requiring a high level of technical skill. Although it seems obvious that wearing the wrong size gloves could impair or prolong tasks involving manual dexterity, the issue has not been formally studied. We tested the hypothesis that wearing the wrong size gloves impairs manual dexterity. We administered a grooved pegboard test to 20 healthy, paid, volunteer health care workers. The subjects performed the test with bare hands and while wearing their preferred size of latex surgical gloves, gloves that were a full size smaller, and gloves that were a full size larger. Each subject did three runs with each size glove and three runs with bare hands. The time necessary to insert pegs was measured with a stopwatch. Peg insertion time was not affected by wearing preferred size gloves (vs. bare-handed) but was increased 7–10% by gloves that were either too small or too large (both effects: P < 0.05 vs. preferred size; both P < 0.001 vs. bare-handed). The subjects reported that the too-small gloves limited hand motion or hurt their hands, whereas the too-large gloves were clumsy but comfortable. Health care workers should wear gloves that fit properly when doing tasks that require manual dexterity. If the preferred size is unavailable, wearing gloves that are too large seems the best alternative.

Evaluation of Glove Damage during Dental Procedures among Dental Specialists in Tabriz.

Background and aims Dental practitioners are prone to occupational risk of infection. This can be prevented in part by wearing gloves. However, for this to be effective, gloves should be intact during the entire course of dental procedure. Leaky surgical latex gloves have been seen in 0.9% of cases before use. As much as 1.9% of latex gloves have been reported to be damaged during dental procedures. In this study, we decided to assess glove damage during dental procedures among dental specialists in Tabriz. Materials and methods Thirty-six dental specialists were selected for this study. Each practitioner received 40 pairs of intact powdered latex gloves. Upon the completion of dental procedures, the gloves were retrieved and any tears were evaluated separately for right and left hands. Data was analyzed using chi-square test. Results 159 punctures were detected in 144 gloves (5%) out of 2880 unpaired gloves used by practitioners. They noticed the tear(s) in 60 cases (2%), however, 99 cases (3%) of tear(s) were not noted during the procedure. The highest rate of glove damage was observed in the prosthodontists’ group (12.3%), which was statistically significant comparing to other groups (p=0.048). The lowest rate of the damage was observed in the oral surgeons’ group (2%) which showed no significant difference (p=0.134). The highest rate of punctures in the gloves was observed in the first and second fingers of the non-dominant hand. Conclusion The damage to 5% of the gloves is highly significant, with a potential role in occupational hazards. The higher rate of leaks in the prosthodontists’ group compared to other groups demands for greater prudence in this field. The high rate of leaks in the first and second fingers of the non-dominant hand requires more attention to this area during daily practice.

Volume measurement of a pediatric ventricular phantom model using three-dimensional echocardiography

Volume measurement of the ventricle is necessary to evaluate cardiac function. Accurate volume measurement of the ventricle by three-dimensional (3D) echocardiography will mark a new step in pediatric cardiovascular diagnosis and treatment. We studied volume measurement of a pediatric ventricular model using 3D echocardiography. The ultrasonic diagnostic setup used in this study comprised a Philips Sonos 7500 ultrasound system with an electronic sector probe of a ×4 matrix phased array transducer. The ventricular model was made from a latex surgical glove. The tip of the third finger of the glove was cut off and fixed to a manifold. The ventricular model was gently placed in a reservoir filled with water. Volumes of physiological saline solution ranging from 2 ml to 50 ml in 2-ml increments were injected into the ventricular model and examined. Twenty-five ultrasound images of the ventricular model were obtained using 4D Cardio View RT 1.2 software. There was excellent correlation and agreement between the injected volumes and the calculated volumes (Y = -0.539 + 1.005X, r = 0.997, four cut plane; Y = -0.191 + 1.006X, r = 0.997, eight cut plane). Thus, accurate volume measurement of the ventricular model by 3D echocardiography was confirmed. Our study demonstrated that 3D echocardiography is highly accurate for volume measurement in a pediatric ventricular model (for volumes of 2 to 50 ml) under static conditions.

Differential expression of allergens on the internal and external surfaces of latex surgical gloves

Background Differences in latex allergen sensitization profiles have been described between children undergoing repeated surgical interventions and health care workers. The purpose of this study was to determine whether such sensitization profiles are associated with differences in the expression of latex allergen between the internal and external surfaces of surgical gloves. Methods Extracts were obtained from whole surgical gloves as well as from their external and internal surfaces. The extracts were centrifuged, filtered, concentrated, dialyzed and lyophilized. The protein profile of the extracts was analyzed using hydrophobic interaction chromatography (HIC) and sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). Immunoblotting was performed using era from two patients with confirmed latex allergy. Latex recombinant allergen-specific IgE in these two patients was determined using a fluorescence enzyme immunoassay (FEIA) method. Latex allergen quantification was determined on both glove surfaces using an ELISA method. Results HIC and SDS-PAGE showed qualitative and quantitative differences in proteins between the internal and external glove surfaces, with the former being much richer in proteins. Immunoblotting of glove extracts using sera from two latex-allergic health workers showed differences between glove surface extracts. ELISA quantification of latex allergens demonstrated that the internal glove surface had high amounts of Hev b 5 and Hev b 6.02 whereas the external surface showed Hev b 1, Hev b 3, and Hev b 6.02. Conclusions Our results reveal substantial differences in the composition of latex allergen profiles between the internal and external surfaces of surgical latex gloves, which may suggest a relationship between latex allergen localization and sensitization routes in different risk groups.

Double gloving to reduce surgical cross-infection.

The invasive nature of surgery, with its increased exposure to blood, means that during surgery there is a high risk of transfer of pathogens. Pathogens can be transferred through contact between surgical patients and the surgical team, resulting in post-operative or blood borne infections in patients or blood borne infections in the surgical team. Both patients and the surgical team need to be protected from this risk. This risk can be reduced by implementing protective barriers such as wearing surgical gloves. Wearing two pairs of surgical gloves, triple gloves, glove liners or cloth outer gloves, as opposed to one pair, is considered to provide an additional barrier and further reduce the risk of contamination. The primary objective of this review was to determine if additional glove protection reduces the number of surgical site or blood borne infections in patients or the surgical team. The secondary objective was to determine if additional glove protection reduces the number of perforations to the innermost pair of surgical gloves. The innermost gloves (next to skin) compared with the outermost gloves are considered to be the last barrier between the patient and the surgical team. We searched the Cochrane Wounds Group Specialised Register (January 2006), and the Cochrane Central Register of Controlled Trials (CENTRAL)(The Cochrane Library Issue 4, 2005). We also contacted glove manufacturing companies and professional organisations. Randomised controlled trials involving: single gloving, double gloving, triple gloving, glove liners, knitted outer gloves, steel weave outer gloves and perforation indicator systems. Both authors independently assessed the relevance and quality of each trial. Data was extracted by one author and cross checked for accuracy by the second author. Two trials were found which addressed the primary outcome, namely, surgical site infections in patients. Both trials reported no infections. Thirty one randomised controlled trials measuring glove perforations were identified and included in the review. Fourteen trials of double gloving (wearing two pairs of surgical latex gloves) were pooled and showed that there were significantly more perforations to the single glove than the innermost of the double gloves (OR 4.10, 95% CI 3.30 to 5.09). Eight trials of indicator gloves (coloured latex gloves worn underneath latex gloves to more rapidly alert the team to perforations) showed that significantly fewer perforations were detected with single gloves compared with indicator gloves (OR 0.10, 95% CI 0.06 to 0.16) or with standard double glove compared with indicator gloves (OR 0.08, 95% CI 0.04 to 0.17). Two trials of glove liners (a glove knitted with cloth or polymers worn between two pairs of latex gloves)(OR 26.36, 95% CI 7.91 to 87.82), three trials of knitted gloves (knitted glove worn on top of latex surgical gloves)(OR 5.76, 95% CI 3.25 to 10.20) and one trial of triple gloving (three pairs of latex surgical gloves)(OR 69.41, 95% CI 3.89 to 1239.18) all compared with standard double gloves, showed there were significantly more perforations to the innermost glove of a standard double glove in all comparisons. There is no direct evidence that additional glove protection worn by the surgical team reduces surgical site infections in patients, however the review has insufficient power for this outcome. The addition of a second pair of surgical gloves significantly reduces perforations to innermost gloves. Triple gloving, knitted outer gloves and glove liners also significantly reduce perforations to the innermost glove. Perforation indicator systems results in significantly more innermost glove perforations being detected during surgery.

Expression of Latex Allergens on Inner and Outer Surfaces of Latex Surgical Gloves

RATIONALE: The purpose of the present study was to determine whether different latex sensitisation profiles between health care workers and surgical patients were associated with differential expression of latex allergens between the internal and external surfaces of surgical gloves.

Adverse Reactions to Latex Products: Preventive and Therapeutic Strategies

Evidence-based infection control/exposure control practices are evolutionary in nature. Elements of historical note were first recorded with the suggestions of Lister for guidelines on aseptic procedures. Others, like Semmelweis, promoted the practice of hand washing by medical students and physicians prior to leaving autopsy suites and before entering the labor and delivery areas of hospitals. Halstead is credited with being the first to use surgical gloves in a clinical setting. While the use of latex surgical gloves became routine by the end of World War I, it wasn't until the adoption of universal precautions by the Centers for Disease Control in 1987 that the use of gloves was officially expanded to cover virtually all aspects of patient care. The ubiquitous use of latex gloves and other latex products in healthcare has resulted in a parallel increase in latex-associated adverse reactions. To provide for a safe environment for both oral healthcare providers and patients alike, clinicians must understand the basis for latex-related adverse reactions, recognize associated signs and symptoms, and initiate appropriate preventive and therapeutic strategies. The recommendations for preventing/minimizing latex allergy in the oral healthcare setting are based on current knowledge and a common sense approach to the problem. Evolving manufacturing technology and improvements in measurement methods (for latex proteins) may lead to changes in these recommendations in the future.

Release of Dithiocarbamates into Sweat from Natural Rubber Latex Surgical Gloves

Abstract The release of zinc dialkyldithiocarbamates from a batch of surgical gloves into the sweat of human subjects was studied. Healthy volunteers from both sexes were asked to don the gloves on both hands for 1 h. The identification and estimation of dithiocarbamate residues released into the sweat were carried out using thin layer chromatography (TLC) and high performance liquid chromatography (HPLC). The thin layer chromatogram showed that zinc diethyldithiocarbamate (ZDEC) accelerator residues were released into the sweat of volunteers. The estimation by high performance liquid chromatography revealed that the amount of ZDEC released varied among the human subjects despite using the same brand of glove. The effect of sweat rate and pH on the amount of ZDEC released into hand sweat was investigated. The results indicated that it may not be possible to derive a relationship between the sweat-extractable ZDEC and sweat rate or pH of hand sweat. The dithiocarbamate release was studied in the laboratory using a physiologically simulated medium, namely, artificial sweat at different pH levels. The glove was filled with artificial sweat and extracted for 1 h at 37 °C. It was found that amount of artificial sweat-extractable ZDEC varied with changes in pH of artificial sweat. Lack of a clear relationship between the sweat-extractable ZDEC and sweat rate or pH of hand sweat indicated that factors such as hand exercise, glove-fit, etc., may also be considered when simulating actual use conditions in vitro.
