Perforation in single- and double-gloving methods for cesarean section.

OBJECTIVE: To compare glove perforation between the single- and double-gloving method in cesarean section. METHOD: Three hundred primary surgeons selected at random to be two equal groups--single and double gloving in cesarean section--at Rajavithi Hospital from 1 November 1997 to 31 March 1998. The gloves were tested by immersing in water. The level of statistical significance was noted at P < 0.05. RESULT: The prevalence of glove perforation was 10.67% and 2% in single- and double-inner glove, respectively, with significant difference. CONCLUSION: The double-gloving method had a significant benefit in protecting the primary surgeons' hands from exposure to blood compared with the single-gloving method in cesarean section.

Monomer permeability of disposable dental gloves.

STATEMENT OF PROBLEM: Studies have suggested that monomers may be able to permeate dental gloves. PURPOSE: This study examined the permeability of disposable dental gloves to 6 kinds of dental monomers. MATERIAL AND METHODS: The permeability of 6 kinds of dental monomers (methyl methacrylate [MMA], 2-hydroxyethyl methacrylate [HEMA], triethyleneglycol methacrylate [TEGDMA], ethyleneglycol dimethacrylate [EGDMA], urethane dimethacrylate [UDMA], and Bis-glycidyl methacrylate [Bis-GMA]) through 5 kinds of dental gloves (latex, powder-free latex, coated latex, polychloroprene, and polyvinyl chloride) was examined for up to 180 minutes at 37 degrees C. The fingers of unused gloves without pin holes were cut and used in the experiments. Five specimens per test group were examined. One type of monomer was poured into each finger and dipped in ethanol. The ethanol for extraction was measured by a spectrophotometer at a wavelength of 210 nm, and the results were analyzed by analysis of variance and the Kruskal-Wallis test (P<.05). RESULTS: Four of the monomers tested (MMA, HEMA, TEGDMA, and EGDMA) permeated the gloves tested, whereas 2 (UDMA and Bis-GMA) did not (P>.01). The amount of monomers permeating the latex in 10 minutes was 0.8 +/- 0.6, 0.6 +/- 0.6, 0.07 +/- 0.1, 0.07 +/- 0.1, 0.1 +/- 0.1 and 0.06 +/- 0.1 microL/mL for MMA, HEMA, EGDMA, TEGDMA, UDMA, and Bis-GMA, respectively. The amount of permeated monomer was then increased in relation to the examination time, and in MMA and HEMA, permeation occurred rapidly during the initial 60 minutes at 3 times the 10-minute values, then continued gradually and linearly. The polyvinyl chloride glove showed the greatest monomer permeability. Two-way analysis of variance showed significant correlations between MMA, HEMA, EGDMA or TEGDMA and UDMA or Bis-GMA (P<.01). Statistical significance was shown between polyvinyl chloride and latex, powder-free latex, coated latex or polychloroprene (P<.01). However, there was no significant relation between any kind of dental monomer and any kind of dental glove. CONCLUSION: Within the limitations of this study, 4 of the monomers tested permeated all of the gloves tested.

Control of airborne latex by use of powder-free latex gloves.

OBJECTIVE: Our objective was to assess airborne latex allergen exposure in the workplace of a hospital laboratory technician with occupational latex sensitization and repeated anaphylactic episodes from this. Her allergic manifestations had cleared only when coworkers changed to powder-free latex gloves. Therefore a laboratory still using powdered latex gloves was selected for comparative airborne latex sampling. DESIGN: The design was a survey. SETTING: We used a hospital hematology laboratory, and a biochemistry laboratory was used for comparison. PARTICIPANTS: The index case with latex allergy is described. An average of 10 employees worked on the day shift in the same laboratory, and 10 employees worked in the biochemistry laboratory studied. MAIN OUTCOME MEASURE: Airborne latex allergen levels obtained by high airflow area sampling were compared in the laboratory using powder-free latex gloves and in the laboratory using powdered latex gloves. RESULTS: Levels were below the level of detection (< 0.02 ng/m3 of latex allergen) in the laboratory using powder-free latex gloves but ranged from 39 to 311 ng/m3 in the laboratory using powdered gloves. CONCLUSIONS: Airborne latex allergen is produced with use of powdered latex gloves. Such usage by coworkers may provoke respiratory and anaphylactic response to latex in sensitized subjects. Use of powder-free gloves by coworkers may enable such patients to continue work in their trained profession and may prevent measurable airborne latex exposure. Affected patients, however, still need to avoid direct latex contact.

Allergic and irritant reactions to rubber gloves in medical health services. Spectrum, diagnostic approach, and therapy.

Delayed-type allergies account for most reactions to gloves. These have been found in 32 of 39 patients (82%) attending our department with occupationally induced contact dermatitis to gloves. Accelerators, mainly of the thiuram group, antioxidants, vulcanizers, organic pigments, and, presumably, glove powder ingredients are known responsible allergens. In contrast, immediate-type allergies to rubber gloves were less frequent (13 of 39 patients [33%] with occupationally induced glove allergies). They usually present as contact urticaria. Responsible allergens are latex, glove powder, and accelerators. On the basis of the numerous glove-related allergens, a comprehensive schedule of diagnostic tests is proposed. In addition, we introduce a new classification of hypoallergenic gloves according to their basic materials and ingredients and thus provide a guideline for individual therapy.

Understanding physicians' intention to use a simple infection control measure: wearing gloves.

OBJECTIVE: The aim of this study was to identify the factors that explain the intention of physicians to wear gloves when contact with blood or body fluids was possible. METHODS: A survey was given to a representative sample of physicians (general practitioners, medical specialist, and surgeons of the Canadian province of Québec). A total of 720 physicians completed the self-administered questionnaire. The respondents' intention to wear gloves, psychosocial variables (attitude, perceived social norm, perceived behavioral control, perceived risk of infection, and habit of wearing gloves), and sociodemographic variables were assessed. RESULTS: A substantial proportion of physicians (80%) had strong intentions to wear gloves when contact with blood and body fluids was possible. Logistic regression indicated that the 3 most important factors explaining intention were perceived behavioral norm, attitudes, and perceived behavioral control. Perceived risk of infections, habit of wearing gloves, and being in a younger age category were additional factors related to intention. CONCLUSIONS: Interventions should reinforce the perception that the use of gloves is the norm among medical professionals. These programs also should emphasize the advantages of wearing gloves, counteract the perceived disadvantages of wearing them, and enhance the ability of physicians to circumvent the difficulties of wearing gloves when required.

Micropunctures of rubber gloves used in oral surgery.

In 720 operations in ambulatory oral surgery, the 2,880 surgical rubber gloves used were tested at the end of operation for perforations not earlier detected (microperforations). Gloves of ordinary thickness (type A) and of a thicker quality (type B) were examined. Perforations were found in 1495% and 22.0% of type A gloves and in 3.2% and 2.0% of type B gloves when oral surgeons and dental students, respectively, were operators. Gloves worn by operation assistants showed a lower incidence of perforation. Before operation, 50 gloves of type A were punctured at the tip of right index finger by a sterile dental probe. Results of bacteriologic examinations of the right index and middle fingers strongly indicated that a high number of bacteria passed through pinholes in the gloves. The intact surgical glove represents an impermeable barrier, protecting not only the operation wound against skin bacteria from the hands of the oral surgeon, but also the oral surgeon against pathogenic microorganisms, in particular hepatitis virus type B, escaping from the oral cavity of the patient.

Glove perforation rate in open lung surgery.

OBJECTIVE: In open lung surgery the surgical access is encircled by the ribs, which should result in a high glove perforation rate compared with other surgical specialities. METHODS: Prospectively the surgeon, first and second assistant and the scrub nurse wore double standard latex gloves during 100 thoracotomies. Parameters recorded were: procedure performed, number of perforations, localization of perforation, the seniority of the surgeon, manoeuvre performed at the moment of perforation, immediate cause of perforation, operation time, performance of rib resection during thoracotomy and time of occurrence of the first three perforations. RESULTS: One thousand, six hundred and seventy-three gloves (902 outer, 771 inner) were tested. In 78 operations perforations occurred. There were 150 outer glove perforations (8.9%, 0-8, mean 1.23), 19 inner glove perforations (1.13%, 0-2, mean 0.19). Cutaneous blood exposure was prevented in 78% of all operations and in 87% of all perforations. The perforation rate for the surgeon, the scrub nurse, the first and the second assistant were 61.2, 40.4, 9.7 and 3.1% of all operations, respectively. Rib resection and a duration of more than 2 h resulted in a significant rise of glove perforation rate (P<0.05). The personal experience of the surgeon and the type of operation did not correlate with glove perforation. The immediate cause leading to perforation was named in only 17 cases (13.7%) and comprised contact with bone (seven), a needle stitch (seven) and a production flaw (three). Leaks were localized mostly on the first finger (18%),second finger, (39%) palm and dorsum of the hand (16%). The average occurrence of all first perforations was 38.7 min (range 3-190) after the beginning of surgery, the second after 63.2 min (range 10-195). Fifty-four first perforations (50.5%) were found during the first 30 min of the operation. CONCLUSIONS: The reported perforation rate of 78% lies in the highest range of reported perforation rates in different surgical specialities. Double gloving effectively prevented cutaneous blood exposure and thus should become a routine for the thoracic surgeon to prevent transmission of infectious diseases from the patient to the surgeon.

Are ophthalmic surgeons aware that starch powdered surgical gloves are a risk factor in ocular surgery?

PURPOSE: To assess the level of awareness among UK ophthalmic surgeons of the potential risks from starch powdered surgical gloves during ophthalmic surgery and to show by electron microscopy that starch granule contamination can occur during ophthalmic surgery. SETTING: A sample (N = 46) of UK ophthalmologists from the North of England, UK. METHODS: Type of glove usage and awareness of the possible risks from starch powdered surgical gloves were assessed by means of a questionnaire sent to ophthalmic surgeons in the North of England. The surface of a polymethylmethacrylate (PMMA) intraocular lens (IOL) handled with a starch powdered surgical glove was examined by electron microscopy for evidence of starch contamination. RESULTS: Of the sampled ophthalmic surgeons (46), 89.1% considered it important to use starch free surgical gloves and the 84.8% already did so. Starch granule contamination was seen by electron microscopy on the surface of a PMMA IOL which had been handled with starch powdered surgical gloves. CONCLUSIONS: Although there has been sporadic attention in the ophthalmic literature to the risks associated with starch powdered surgical gloves in ophthalmology, up to 15% of UK ophthalmic surgeons may still be using starch powdered gloves. The authors show that starch powder contamination of ophthalmic materials can actually occur and remind ophthalmologists that this has been reported in the literature as a possible cause of sterile intra and extraocular inflammation.

Reduction of use of latex gloves in food handlers: an intervention study.

Frequent latex glove use is a risk factor for the development of latex allergy. With the increase in latex glove use, latex allergy has become more prevalent. There are a number of occupational groups in which the use of latex gloves is both inappropriate and even hazardous, including food handlers, where the hazard relates particularly to their latex-sensitive customers. The aim of this study was to assess both the use of latex gloves by food handlers and the impact of an intervention study on reducing latex glove use. This was done at the Queen Victoria Market in Melbourne, Australia. We found that 10 out of 30 stalls (33%) used latex gloves, and that following a short education program, this was reduced to 1 stall (3%, p=0.006). The potential to reduce latex glove use by using this intervention study was 93% (95% confidence interval of 54%-100%). We recommend that food handlers be educated during their training, not only about hygiene issues, but also about the appropriate type of glove to wear, in order to prevent both the development of a new occupational group at risk of becoming allergic to latex, but more importantly to protect their latex-sensitive customers.

An assessment of the incidence of punctures in gloves when worn for routine operative procedures.

The value of glove wearing as part of dental surgery cross-infection control regimen is negated if gloves are punctured during use. An assessment of the procedures most likely to give rise to glove puncture is therefore of importance. Accordingly, 892 gloves worn by two dentists in general practice were examined for punctures, after being used in one of seven common operative procedures. It was found that gloves used for the treatment procedures investigated had a significantly higher proportion of punctures than unused gloves of the same type. Gloves used for surgical extraction showed the highest proportion punctured (16%). There was no significant difference in puncture frequency between the gloves worn on left or right hands irrespective of procedure.

The influence of dental gloves on the setting of impression materials.

The increased wearing of gloves during dental treatment has created new problems for general dental practitioners. One of these is the retarded set or total inhibition of addition silicones caused by natural latex gloves. This study was designed to test different gloves and impression materials in common use. Eight latex gloves, selected with different properties representing all possible types, together with four non-latex gloves, made of neoprene, styrene-butadiene, polyethylene and polyvinylchloride, were tested. As a control, mixing with bare hands and with maize starch was carried out. The viscosity changes of five types of impression materials (polyvinylsiloxanes, condensation silicones, alginates, polyether and polysulphides) were measured with a Zwick hardness tester to give the Shore A hardness. No impression materials other than polyvinylsiloxanes were affected by pure latex gloves and those only by two brands. All other impression materials can be mixed and handled with gloved hands without affecting their setting time. The retarded set of polyvinylsiloxanes caused by natural latex gloves is not so widespread as had previously been thought.

Intraoperative contamination of synthetic vascular grafts. Effect of glove change before graft implantation. A prospective randomised study.

OBJECTIVES: to investigate the incidence of intraoperative graft contamination, bacterial species and the influence of change of surgeon's gloves on contamination. DESIGN: a prospective randomised study. MATERIALS AND METHODS: forty patients had implantation of synthetic vascular grafts. All patients received intraoperative cloxacillin (2.0 g) or clindamycin (0.6 g) intravenously. The procedures were randomised to two groups: Group 1 - surgeons changed the gloves before the first contact with the vascular prosthesis and Group 2 - operation without glove change. The growth of all bacterial species from graft segments and from the gloves was recorded. The susceptibility to antibiotics was tested. RESULTS: the number of contaminated grafts was similar in the two groups. Growth of bacteria was recorded from 92.5% (37/40) of the graft segments and 33% (51/156) of glove imprints. Of the cultured species, 75% and 47%, respectively, were identified as coagulase-negative staphylococci (CNS). Twenty-eight per cent of CNS were resistant to cloxacillin, 15% to clindamycin, and 10% to cloxacillin and clindamycin. In all, 25% of the CNS strains were resistant to the prophylactic antibiotic used. In 50% of cases, the antibiogram of the CNS strain recovered from gloves agreed with that of the strain harvested from the graft. CONCLUSIONS: a high incidence of graft contamination was found which was not reduced by changing gloves. However, changing gloves did seem to reduce the number of bacterial species.

In vivo testing of the protection provided by non-latex gloves against a 2-hydroxyethyl methacrylate-containing acetone-based dentin-bonding product.

In dentistry, allergic contact dermatitis to acrylates and allergic contact urticaria to latex are important occupational hazards. There is a need to identify non-latex gloves which are suitable for dental work but at the same time provide adequate protection against acrylate monomers. In a previous study, a new open-chamber system was used for testing the in vivo protection of 6 different gloves against an acrylate-containing ethanol-based dental adhesive. A nitrile glove gave the best protection among the gloves suitable for dental work. In the present study, the test model was used to investigate the in vivo protection of 7 non-latex gloves against a dental bonding product containing 2-hydroxyethyl methacrylate (2-HEMA) in an acetone/water vehicle. Eight 2-HEMA-allergic patients participated. Two neoprene gloves gave the best protection. The protection of the poorest glove was comparable to that of the positive control (no glove). The study produced in vivo data useful in the implementation of individual preventative measures against contact allergy to acrylates.

Touch sensitivity through latex examination gloves.

Two studies were conducted to empirically evaluate individuals' touch sensitivity while wearing latex medical-examination gloves. In Experiment 1, three sensitivity threshold measures (two-point, von Frey, and thumb-index finger opposition) were used in three conditions--no glove, best-fitting glove, and ill-fitting glove. No effect of glove condition was found for the two-point measure, but significant effects were found for the von Frey and finger-opposition measures. In Experiment 2, participants attempted to sense the presence or absence of monofilament fibers of different diameters. Glove condition (no glove, best-fitting, and ill-fitting) and touch strategy (active vs. passive) were manipulated for each participant. Although there was no overall effect for glove condition, active touch proved consistently superior to passive touch.

Investigation of volatile nitrosamines in disposable protective gloves.

Laboratory personnel of Eastern Regional Research Center, USDA, are required to wear disposable latex or vinyl gloves for certain analyses involving nitrosamines. In order to assess possible exposure of the wearers of these gloves, a limited survey was carried out on the volatile nitrosamine content in disposable protective gloves. Six latex gloves, nonsterile and sterile, surgical and nonsurgical, from four companies, and four vinyl gloves from three companies were analyzed. N-nitrosodimethylamine (NDMA) and N-nitrosopiperidine (NPIP) were the primary nitrosamines detected. Five of the six latex gloves contained 37-329 ppb NDMA and 115-1879 ppb NPIP, all confirmed by gas chromatography-mass spectrometry (GC-MS); one glove contained no detectable trace of NDMA or NPIP. Of the four vinyl gloves, one contained 19 ppb NDMA and 759 ppb NPIP, both confirmed by GC-MS, one contained 6 ppb apparent NDMA and no detectable level of NPIP, and the remaining two contained no detectable levels of NDMA and NPIP.

Effect of the mosquito repellent DEET and long-wave ultraviolet radiation on permeation of the herbicide 2,4-D and the insecticide DDT in natural rubber gloves.

Studies were conducted to determine the effect of a commonly used insect repellent, DEET (N,N-diethyl-m-toluamide), on the permeability of rubber gloves used as chemical protective clothing (CPC) by pesticide applicators. Glove permeation analysis was conducted with an automated in vitro diffusion analysis (AIDA) method employing an in-house, flow-through permeation cell design. Permeation of 14C-ring-labeled 2,4-D (2,4-dichlorophenoxyacetic acid) in natural rubber glove material was 2.4 +/- 1.81% at 48 hr after treatment of the glove with 2,4-D applied with DEET; this was not significantly different (Student's t-test; p less than 0.05) from 3.2 +/- 3.46% permeation of 2,4-D observed without DEET. Similarly, there was no significant difference between the permeation of pp'-DDT (1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane) applied with DEET (11.7 +/- 5.02%) and without DEET (11.4 +/- 4.86%) to natural rubber glove material. Scanning electron microscopy of the natural rubber glove material, however, demonstrated disruption of the surface ultrastructure following a 24-hr treatment with DEET. The AIDA analysis also suggested that exposure of the glove material to long-wave ultraviolet (UVA) radiation enhanced the glove permeability to 2,4-D (6.2 +/- 0.73% [+UVA]; 0.3% +/- 0.14% [-UVA]) but had no effect on the permeation of DDT. Because the CPC of pesticide applicators is commonly exposed to solar UVA, this finding may raise concerns about the efficacy and safety of CPC in general.

Physicians' perceptions about increased glove-wearing in response to risk of HIV infection.

Glove-wearing attitudes of 375 physicians, representing 56% of all physicians surveyed, were ascertained. Although the majority were comfortable with their current glove use, 33% preferred wearing them more frequently. The most common reasons for not wearing gloves were a low likelihood of disease transmission and fear of offending patients. Many physicians felt that more frequent glove use in examining human immunodeficiency virus- (HIV)-positive patients might reduce rapport and diminish the adequacy of physical examination procedures, but only 11% felt that increased glove use would compromise overall care of HIV-positive patients. With regard to all patients, 33% felt that increased glove use in examinations would compromise care. Additionally, 56% of physicians stated that they were somewhat concerned about HIV infection. Glove-wearing preferences were significantly associated with greater concern about infection, a younger age and more frequent exposure to blood and body secretions. Contact with high-risk patient groups was not associated with glove-wearing preferences.

Permeation of cytotoxic formulations through swatches from selected medical gloves.

The permeability of selected medical glove materials to various cytotoxic agents is described. Fifteen cytotoxic agents were prepared at the highest concentrations normally encountered by hospital personnel. Four single-layer and two double-layer glove systems made of two materials--latex and neoprene--were exposed to the drugs for 30, 60, 90, 120, 150, and 180 minutes. Circular sections of the glove material were cut from the cuff and evaluated without any pretreatment. Permeability tests were conducted in an apparatus consisting of a donor chamber containing the cytotoxic solution and a collection chamber filled with water (the acceptor medium). The two sections were separated by the glove material. Permeating portions, collected in water as the acceptor medium, were analyzed by either ultraviolet-visible light spectrophotometry or high-performance liquid chromatography (HPLC). Permeation rates were calculated on the basis of the concentration of the cytotoxic agent in the acceptor medium. Spectrophotometric measurements were taken every 30 minutes, and HPLC analysis was performed at the end of the three-hour period. Average permeation rates for 14 drugs were low (< 0.2 nmol/[min.cm2]) or no permeation was detected in all glove materials. All glove materials tested were impermeable to most of the cytotoxic agents over a period of three hours. Carmustine was the only agent that substantially permeated single-layer latex glove materials. Permeation of most tested cytotoxic formulations was low through swatches of material from various medical gloves.
