| Protection \ Cut-Resistant | Protective Value of Surgical Gloves
| Protective Value of SurgicaI Gloves Including the ''Cut Resistant Variety" Alexander A. Fisher, MD
Rubber gloves provide a relatively effective barrier against the human immunodeficiency virus and other viruses. However, it should be noted that the Food and Drug Administration and the American Society for Testing and Materials accept a current quality level of 1.5 percent for holes by a 1000-mL water test. Thus, some rubber gloves may have holes even before use. (1) Wearing two pair of rubber gloves is therefore usually advised. Buxo(2) states that double latex gloves offer minimal resistance to punctures, cuts, and abrasions. Using double gloves seems to be ineffective in protecting the surgeon if unavoidable injuries occur. Multiple protective devices have been proposed, such as the use of thick vinyl gloves, chain-linked steel undergloves, continuous filament stainless steel fibers knitted with cotton, thicker cotton undergloves, use of dilute hypochlorite solution between layers of gloves, and protective shields in areas of the glove most likely to suffer trauma during surgical procedures. None of these proposed solutions seem to satisfy the demand for protection, particularly against needle puncture, while retaining dexterity and comfort.
INJURIES TO DERMATOLOGIC SURGEONS Kasper and Wagner(3) conducted an anonymous survey on one hundred randomly selected fellows of the American So- ciety for Dermatologic Surgery. Forty-one respondents provided information about their expenence with percuta- neous injury. Causes of injury during 6,278 invasive proce- dures performed during a one-month period included suture needlesticks (two injuries), injection needlestick (two), nee- dle recapping (one), scalpel blade (one), skin hook (one), and an injury during the transport of an instrunent (one). Thus, of eight injuries reported, five were to derma- tologic surgeons and three to other staff members. Two of the injuries were incurred during suturing and three were caused by injection needles. Thus, five of the eight injuries were due to some form of needlestick. In addition, one scal- pel blade injury and one skin hook injury occured. Five der- matologic surgeons and two nurses reported injuries. A dermatologic surgeon accounted for the one reported nee- dle recapping injury. Four of the five injuries to dermatolog- ic surgeons occurred to the dominant hand. Two of these were due to suture needlesticks and two were due to injec- tion needlesticks. One nurse was injured by a skin hook while she was assisting in surgery. Another nurse was in- jured when she was punctured by an injection needle that was being transported by another nurse. CUT RESISTANT GLOVES Although the fibers used in cut resistant gloves are also used in bulletproof vests, the manufacturers of these gloves emphasize that the gloves are not needle puncture proof or "cut proof," but are "cut resistant." It is suggested that these gloves be used as liners between two rubber gloves. FIBERS USED IN CUT RESISTANT GLOVES Spectra PolyethyEene Fibers (Allied Signal)-This recently in- troduced fiber is said to be highly resistant to cuts and abra- sions. Such fibers are used in Paraderm and Perry liners. Centurion (Biomet)--This combination of stainless steel and polyethylene fibers is said to be "a breakthrough in continuous filament knitting technology which allows stainless steel to be encased in synthetic fibers, providing the most cut resistant fabric available. Unlike thicker spun bers, Centurion glove liners are thin enough to allow for extraordinary tactile sensitivity". Repel Cut Resistant De Puy (DuPont)--This prod- uct contains Kevlar Aramid synthetic fibers and a poly- methacrylate. It is not yet clear whether the polymethacry- late in Kevlar will cause any reaction in orthopedic sur- geons or dentists who may become sensitive to methyl methacrylate. SPECTRA FIBER COMPARED WITH KEVLAR Spectra fiber is an extended chain polyethylene polymer. Unlike Spectra, DuPont Kevlar is a type of polymer based on chemicals with many benzene rings. Terephthalic acid and paraphenylenediamine are the chemicals that DuPont uses to make Kevlar aramid, which is registered with the Federal Trade Commission.
CRITIQUE OF THE USE OF CUT RESISTANT GLOVES Buxo (2) states that the results of his study suggests that the Spectra-lOOO fiber offers protection against cuts and abra- sions. It does not provide protection against punctures with needles or other sharp instruments. The user question- naires suggest that, in its present form, the liner is relative- ly comfortable to most users and provides an adequate fit with only a mild to moderate loss of dexterity. Chain-linked steel gloves revealed superior cut re- sistance using the slicing technique; however, upon impact the resistance was similar to the Spectra glove. Buxo (2) finds that steel gloves are significantly heavier and difficult to slide over or under latex gloves and consequently have not gained acceptance among users. The heavier Spectra glass glove showed superior cut resistance during the slicing and impact cutting trials.
THE PREVENTION OF NEEDLE PUNCTURES Kasper and Wagner(3) found that 52 percent of one hundred dermatologic surgeons allowed needles to be recapped by hand although the Centers for Disease Control have recom- mended against this practice.(4) Hussain, Latif, and Choud- hary(5) also found needle punctures very common among general surgeons. The finding that the majority of injuries to dermato- logic surgeons occurs to the index and middle fingers of the dominant hand is consistent with the previous observation of Gross et al(6) who found more perforations in the dominant than nondominant handed gloves of dermatologic surgeons. In their experience, they have discemed that many derma- tologic surgeons pick up instruments off the surgical tray themselves, possibly increasing their chances of self-injury. Injury to the dominant hand seems to be emerging as a spe- cial risk to those who practice dermatologic surgery.
COMMENTS Prior to use, rubber gloves may contain holes that make it advisable to use two pair of rubber gloves instead of one. It is ironic that cut resistant gloves made of materials that are used in the manufacture of "bulletproof' clothing do not protect the surgeon from needle punctures, which are the most common injuries they sustain. What is urgently need- ed is a puncture proof thimble-like object in the finger ends of rubber and cut resistant gloves that provides tactile satis- faction.

DELASCO COMMENT: Since routine recapping of needles is now illegal under OSHA rules, and substantial fines may be levied if an employee is injured with a needlestick, as a result of violation of the OSHA rules, it can be expected that needles will be or should be handled in a safe manner (immediately discarded in a sharps container after use) so that needlesticks injury should be close to eliminated. Cut Resistent gloves will now protect from much of the balance of injuries.
