Syneture stainless STEEL suture. A collective review of its performance in surgical wound closure.

Syneture (division of U.S. Surgical, division of Tyco Healthcare, Norwalk, Connecticut, USA) STEEL sutures are monofilament stainless steel sutures composed of 316L stainless steel conforming to ASTM Standard F138 grade 2 (" Stainless steel bar and wire for surgical implant"). STEEL sutures meet all requirements established by the United States Pharmacopeia (USP) for nonabsorbable surgical sutures. Steel sutures are for use in abdominal wound closure, intestinal anastomosis, hernia repair, sternal closure, and skin closure. They are attached to the following types of surgical needles: Roto-Grip Needles and SCC Needle. The sutures and needles are packaged in a Mylar/Tyvek outer envelope. The purposes of this clinical review are two fold. First, we will report the performance of the Syneture STEEL suture product in the largest studies of suture performance ever reported in the literature. In addition, we will provide comprehensive information from the surgical literature that highlights the unique benefits of stainless steel sutures for the following wound closure techniques: sternal fixation, abdominal wound repair, inguinal hernia repair, and skin wound closure. Consorta Inc. (Rolling Meadows, Illinois), a leading healthcare resource management group purchasing organization, and Syneture, jointly with a clinician task force, designed a reproducible surgical evaluation program for needles and sutures in a large cooperative of healthcare systems. Because of the subjective nature of the more commonly used suture selection techniques, a nonexperimental observational study approach was designed to replace perception of performance characteristics with actual clinical experience. In a report involving 19 Consorta shareholder hospitals, they discussed the preliminary part (Phase I) of a large nonexperimental observational study of the clinical performance of surgical needles and sutures. Performance characteristics of the sutures and needles produced by Syneture that were evaluated in 3407 surgical procedures included packaging/ease of opening, needle strength and sharpness, tissue drag, knot security, tensile strength, clinically acceptable determinations, and clinically unacceptable determinations. In this preliminary study, the surgeons concluded that the needles and sutures were clinically acceptable in 98.1% of the evaluations. Armed with this favorable experience, we wanted to expand this observational study to an entirely new group of shareholder hospitals that had a larger number of participating hospitals (Phase I, 19 hospitals; Phase II, 42 hospitals). This more than doubling of hospital observational base dramatically increased the number of patients and performance evaluations. In the Phase II expanded program involving 42 hospitals, the number of patients (8939) and the number of evaluations (25,545) were more than twofold the preliminary study. In the phase I multicentric evaluation of Syneture surgical sutures, the performance of 9266 sutures was evaluated. Of these performance evaluations, 130 evaluations focused on Syneture STEEL sutures. The surgeons were especially pleased by the performance of this suture product, with 129 Syneture STEEL products being judged as clinically acceptable in their performance. Only one Syneture STEEL suture was judged to be unacceptable in its performance, resulting in a 99.2% acceptability rating. In the expanded phase II evaluation of Syneture suture products, the performance evaluation involved 25,545 surgical suture evaluations. The performance of Syneture STEEL sutures was judged in 215 cases. Of these product performance evaluations, 207 were judged to be clinically acceptable in their performance (96.3%). It is important to emphasize that the phase I and phase II observational studies evaluated the performance of other sutures besides monofilament steel sutures. These comprehensive suture and needle performance evaluations included the following additional sutures: Plain Gut, Mild Chromic Gut, Chromic Gut, DEXON II, DEXON S, MAXON, BIOSYN, SOFSILK, SURGILON, BRALON, MONOSOF, DERMALON, SURGIDAC, POLY-SORB, TI.CRON, SURGIPRO, SURGIPRO II, NOVAFIL, VASCUFIL, and FLEXON. Finally, we provide a collective review of the literature that shows the reliable performance of monofilament stainless steel sutures in the following wound closure techniques: sternal fixation, abdominal wound closure, inguinal hernia repair, and skin wound closure.

Revolutionary advances in medical waste management. The Sanitec system.

It is the purpose of this collective review to provide a detailed outline of a revolutionary medical waste disposal system that should be used in all medical centers in the world to prevent pollution of our planet from medical waste. The Sanitec medical waste disposal system consists of the following seven components: (1) an all-weather steel enclosure of the waste management system, allowing it to be used inside or outside of the hospital center; (2) an automatic mechanical lift-and-load system that protects the workers from devastating back injuries; (3) a sophisticated shredding system designed for medical waste; (4) a series of air filters including the High Efficiency Particulate Air (HEPA) filter; (5) microwave disinfection of the medical waste material; (6) a waste compactor or dumpster; and (7) an onboard microprocessor. It must be emphasized that this waste management system can be used either inside or outside the hospital. From start to finish, the Sanitec Microwave Disinfection system is designed to provide process and engineering controls that assure complete disinfection and destruction, while minimizing the operator's exposure to risk. There are numerous technologic benefits to the Sanitec systems, including environmental, operational, physical, and disinfection efficiency as well as waste residue disinfection. Wastes treated through the Sanitec system are thoroughly disinfected, unrecognizable, and reduced in volume by approximately 80% (saving valuable landfill space and reducing hauling requirements and costs). They are acceptable in any municipal solid waste program. Sanitec's Zero Pollution Advantage is augmented by a complete range of services, including installation, startup, testing, training, maintenance, and repair, over the life of this system. The Sanitec waste management system has essentially been designed to provide the best overall solution to the customer, when that customer actually looks at the total cost of dealing with the medical waste issue. The Sanitec system is the right choice for healthcare and medical waste professionals around the world.

Scientific basis for the selection of absorbent underpads that remain securely attached to underlying bed or chair.

The occurrence of pressure ulcers in patients is very high in certain high-risk groups. These special high-risk groups include elderly patients, patients with spinal cord injuries, or any individual with an impaired ability to reposition. Prevention of pressure ulcers is by far the best treatment of this condition, warranting certain interventions and preventive measures. One major risk factor to be minimized is the exposure of skin to moisture. Underpads are often used to protect the skin of patients who are incontinent. These products effectively absorb moisture and present a quick-drying surface to the skin. The construction of an underpad should accomplish three goals. First, its backing should have a low coefficient of friction to prevent frictional skin injuries. Second, an inner absorbent core should rapidly contain moisture and disseminate it throughout the entire pad. Third, the core and coverstock should successfully work together to retain moisture and prevent wet-back or fluid return. The purpose of this study was to determine the performance of three commercially available underpads in reducing the development of pressure sores in patients at high risk. In this study we selected three underpads that could be securely attached to either the underlying bed or the chair. The three performance parameters examined were absorbent capacity, wetback prevention, and holding security of the underpads. Measurements of these performance parameters can be easily replicated in other laboratories. The results of these studies provide a scientific basis for selecting and purchasing an underpad to prevent pressure ulcers in patients. In this comprehensive evaluation, we assess an absorbent underpad with polyethylene flaps and two absorbent underpads with adhesive. The absorbent capacity results showed Tranquility SlimLine Peach Sheet to be the most absorbent. The wet-back results showed Tranquility SlimLine Peach Sheet to be the only underpad with no wet-back, with no fluid returning through the coverstock. The Tranquility SlimLine Peach Sheet Underpad has four adhesive strips attached to each of the four ends of the underpad surface. These 5 cm long strips secure well to the seat of a wheelchair or chair. In contrast, they do not maintain secure attachment to a bed sheet, making the bed sheet vulnerable to urine or stool penetration. When the clinical staff used the Tuckable on the bed surface, they were all impressed by the secure fit of the plastic wings, which easily tucked around the mattress. The wings remained in place throughout the night. Realizing the stability of the Tuckable underpads, the clinical staff suggested that the Tuckable underpad be placed first on the bed, then the Tranquility SlimLine Peach Sheet can be placed on top of the Tuckable underpad, using the four adhesive strips to attach it to the surface of the Tuckable underpad. All of the staff were impressed that the adhesive strips remained securely attached to the Tuckable. This clinical decision was found to be very cost efficient, because the Tuckable could remain in place more than a week without changing. Even though we have developed a unique scientific basis for the selection of underpads for use on either chairs or beds, it can be a financial challenge to the patient or healthcare setting to use these products, because Medicare provides no reimbursement for underpads, an invitation to pressure ulcer formation. In the absence of responsible federal government policy, we are making recommendations for the selection of a cost-conscious and responsible company that sells incontinence products--Home Deliver Incontinent Supplies Co., Inc., (HDIS), Olivette, Missouri.

Vaccine information statements. Revolutionary but neglected educational advances in healthcare in the United States.

The purpose of this report is to provide further information about vaccine information statements (VISs) that are revolutionary but neglected educational advances in the United States. Because the use of VISs is mandated by the Federal Government in every individual being immunized, it is the goal of this report to further awaken health professionals and society to the mandatory use of these superb educational statements. With the passage of the National Childhood Vaccine Injury Act of 1986, the Federal Government required that VISs would be given to all vaccine recipients. As of September 2001, the VISs that must be used are diphtheria, tetanus, pertussis, (DTaP); diphtheria, tetanus (Td); measles, mumps, rubella (MMR); polio (IPV); hepatitis B; Haemophilus influenzae type b (Hib); varicella; and pneumococcal conjugate. Copies of the VISs are available at www.cdc.gov/nip/publications/VIS. The National Childhood Vaccine Injury Act of 1986 mandated that all health care providers report certain adverse events that occur following vaccination. As a result, the Vaccine Adverse Events Reporting System (VAERS) was established by the FDA and the Centers for Disease Control and Prevention (CDC) in 1990. In order to reduce the liability of manufacturers and healthcare providers, the National Childhood Vaccine Injury Act of 1986 established the National Vaccine Injury Compensation Program (NVICP). This program is intended to compensate those individuals who have been injured by vaccines on a no-fault basis. While the use of VISs has been mandated since 1996, a national survey of private practice office settings has revealed that many immunized patients do not receive the VISs. When these forms were used, physicians rarely initiated discussions regarding contraindications to immunizations or the National Vaccine Injury Compensation Program. Fortunately, the state boards of medical examiners, like the one in Oregon, are taking a strong stand for the use of VISs, with the warning that failure to use a VIS may result in disciplinary action. Our nation and practicing physicians must be awakened to the importance of the use of VISs to ensure that every vaccinated individual receives this statement at the time of vaccination.

Scientific basis for the selection of emergency medical examination gloves for emergency medical technicians, paramedics, firefighters, and emergency department personnel. An update.

The use of powder-free natural rubber or latex-free emergency medical examination gloves is especially important to emergency medical technicians, paramedics, firefighters, and emergency department personnel to avoid eliciting an allergic reaction in the latex sensitized patient. The majority of our emergency medical technicians, paramedics, and firefighters are now wearing powder-free emergency medical examination gloves that comply with the stringent codes and standards established by the National Fire Protection Association (NFPA), while very few hospital emergency department personnel have been provided with NFPA-approved gloves. There are four well-defined goals of this report that will assist emergency medical services, fire departments, and hospitals in the selection and purchase of emergency medical examination gloves. First, we will review again the stringent regulations for emergency medical examination gloves that are outlined by the NFPA. This design and performance standard was devised by the NFPA to address protective clothing for emergency medical operations. The design and performance requirement of the emergency medical examination gloves were described in the NFPA 1999, Standard on Protective Clothing for Emergency Medical Operations, 1997 Edition. As of September 2003, the emergency medical examination glove must meet the new design and performance requirements of emergency medical examination gloves discussed in NFPA 1999, Standard on Protective Clothing for Emergency Medical Operations, 2003 Edition.

Devastating injuries in healthcare workers: description of the crisis and legislative solution to the epidemic of back injury from patient lifting.

The purpose of this report is to describe a crisis in healthcare, disabling back injuries in US healthcare workers. In addition, outlined is the proven solution of safe, mechanized, patient lifting, which has been shown to prevent these injuries. A "Safe Patient Handling--No Manual Lift" policy must be immediately instituted throughout this country. Such a policy is essential to halt hazardous manual patient lifting, which promotes needless disability and loss of healthcare workers, pain and risk of severe injury to patients, and tremendous waste of financial resources to employers and workers' compensation insurance carriers. Healthcare workers consistently rank among top occupations with disabling back injuries, primarily from manually lifting patients. Back injury may be the single largest contributor to the nursing shortage. Reported injuries to certified nursing assistants are three to four times that of registered nurses. A national healthcare policy for "Safe Patient Handling--No Manual Lift" is urgently needed to address this crisis. Body mechanics training is ineffective in prevention of back injury with patient lifting. Mandated use of mechanical patient lift equipment has proven to prevent most back injury to nursing personnel and reduce pain and injury to patients associated with manual lifting. With the national epidemic of morbid obesity in our country, innovative devices are available for use in emergency medical systems and hospitals for patient lifting and transfer without injury to hospital personnel. The US healthcare industry has not voluntarily taken measures necessary to reduce patient handling injury by use of mechanical lift devices. US healthcare workers who suffer disabling work-related back injuries are limited to the fixed, and often inadequate, relief which they may obtain from workers' compensation. Under workers' compensation law, healthcare workers injured lifting patients may not sue their employer for not providing mechanical lift equipment. Discarding healthcare workers disabled by preventable back injuries is an abuse which legislators must remedy. In addition, Medicare reimbursement policies must also be updated to allow the disabled community to purchase electrically operated overhead ceiling lifts. The US lags far behind countries with legislated manual handling regulations and "No Lifting" nursing policies. England and Australia have had "No Lifting" nursing policies in place since 1996 and 1998, respectively. The National Occupational Research Agenda (NORA) recognized a model in 2003 for reduction of back injuries to nursing staff in US healthcare facilities. Also in 2003, the American Nurses Association called for elimination of manual patient handling because it is unsafe and causes musculoskeletal injuries to nurses. The first state legislation for safe patient handling passed both houses in California but was vetoed by the Governor in September 2004. California and other states are preparing to (re)introduce legislation in January 2005. A national, industry-specific policy is essential to quell the outflow of nursing personnel to disability from manual patient lifting.

Difficult wounds: an update.

The purpose of this collective review is to describe revolutionary advances in the treatment of Gardner's syndrome (GS), pseudofolliculitis barbae, nasal septal perforation, factitious wounds, and hidradenitis suppurativa (HS). Gardner's syndrome or familial polyposis has various manifestations that appear to be controlled by a single genetic locus. Apart from the large bowel adenomas, which are always present, a common extracolonic symptom of Gardner's syndrome is the occurrence of epidermal cysts. These cysts can be seen before the intestinal polyps are evident. Because epidermal cysts in patients with Gardner's syndrome are always benign, we excise these cysts using incisions that are commonly used for rhytidectomy. Pseudofolliculitis barbae, a pseudofolliculitis caused by ingrown hairs, effects 85% of blacks who shave their beards. When this disease is allowed to progress to keloid formation, we use a surgical approach that includes excision of the keloidal scar, meticulous debridement of all residual ingrown hairs in the underlying wound, and coverage of the defect with a split-thickness skin graft. More recently, laser therapy has revolutionized the treatment of pseudofolliculitis barbae and has enabled a cure for the first time for those plagued with this disorder and for whom a beardless face is acceptable. Nasal septal perforation is a well recognized complication of septal surgery. Other iatrogenic causes of perforation include cryosurgery, electrocoagulation for epitaxis, nasotracheal intubation, or nose packing. In recent years drugs such as cocaine account for an increasing number of perforations. It has only been with the use of an external approach for the repair of the nasal septal defect that surgical closure has become easier and more reliable. The external approach allows for greater surgical closure and enables the surgeon to use both hands with the aid of binocular vision to mobilize and suture local mucosal advancement flaps and the intraseptal connective tissue grafts. More recently, surgeons have repaired large septal perforations with a radial forearm free flap. Because of its availability and deep emotional significance, the skin is a common site for self-destructive behavior with the development of factitious skin wounds. When suspected, psychiatric care must proceed immediately. Second, the ulcer can then be healed by appropriate techniques and wound repair. It is important to emphasize that the treating physician must first confront the patient, and then a psychiatrist should provide appropriate psychotherapy. Hidradenitis suppurativa is an inflammatory disease of the skin and subcutaneous tissue that occurs in apocrine-gland-bearing areas distributed in the axilla, mammary nipple areola, mons pubis, groin, scrotum, perineum, perianal region, and umbilicus. The condition has an insidious onset. The susceptibility of women's axillary skin to hidradenitis suppurativa may be related, in part, to the practice of axillary removal of hair with a safety razor. Consequently, the use of safety razors must be avoided and replaced with the use of an electric razor. The method of treatment will vary with the stage of the disease. Treatment of the chronic stage of axillary hidradenitis suppurativa is primarily surgical. More recently, carbon dioxide laser treatment, with healing by secondary intention, is proving to be a rapid, efficient, and economic treatment of this difficult wound.

Modern concepts of treatment and prevention of chemical injuries.

Chemical injuries are commonly encountered following exposure to acids and alkali, including hydrofluoric acid, formic acid, anhydrous ammonia, cement, and phenol. Other specific agents that cause chemical burns include white phosphorus, elemental metals, nitrates, hydrocarbons, and tar. Even though there are more than 65,000 chemicals available on the market, and an estimated 60,000 new chemicals produced each year, the potential deleterious effects of these chemicals on humans are still unknown. The Superfund Amendments and Reauthorization Act contains extensive provisions for emergency planning and the rights of communities to know about toxic chemical releases. Since 1990, the Agency for Toxic Substances and Disease Registry (ATSDR) has maintained an active, state-based Hazardous Substances Emergency Events Surveillance (HSEES) system to describe the public health consequences risked by access to hazardous chemicals. Most chemical agents damage the skin by producing a chemical reaction rather than hyperthermic injury. Although some chemicals produce considerable heat as a result of an exothermic reaction when they come in contact with water, their ability to produce direct chemical changes on the skin accounts for the most skin injury. Specific chemical changes depend on the agent, including acids, alkalis, corrosives, oxidizing and reducing agents, desiccants, vesicants, and protoplasmic poisons. The concentration of toxic agent and duration of its contact primarily determine degree of skin destruction. Hazardous materials (hazmats) are substances that may injure life and damage the environment if improperly handled. HAZMAT accidents are particularly dangerous for responding personnel, who are in danger from the moment of arrival on the scene until containment of the accident. Consequently, the Superfund Amendment and Reauthorization Act mandates community preparedness for dealing with hazmat accidents. Paramedics and members of the hazmat response team (usually firefighters) must work together to identify toxic chemicals and assess hazardous environments. The contingency plan for hazmat management can be divided into two parts: initiation of the site plan and evacuation. In coping with hazmat incidents, two distinct goals must be achieved concomitantly. First, hazmats must be contained, fire and explosions must be extinguished, and the site eventually must be cleaned. Second, those exposed to hazmats must be treated at the scene of contamination as well as in the hospital and rehabilitation setting.

Rubella and congenital rubella (German measles).

Rubella, also known as German measles, is usually a very mild infection that can have devastating effects in certain instances. It is a pleomorphic RNA virus in the Togaviridae family of the genus Rubivirus. It typically causes a scarletiniform rash, cervical lymphadenopathy, and mild constitutional symptoms, but in older children and adults, especially women, it may be more severe, with joint involvement and purpuric rash. Infection during the first 12 weeks of pregnancy results in congenital infection and/or miscarriage in 80-90% of cases. The congenital rubella syndrome (CRS) involves multiple organ systems and has a long period of active infection and virus shedding in the postnatal period. For these reasons, the rubella vaccine program was instituted in 1969, and the incidence of rubella infection in the United States has since declined by 99%. Rubella has been recognized as a disease for approximately 200 years, and it has since been found that humans are the only natural reservoir for the rubella virus. Virus is present in nasopharyngeal secretions, blood, feces, and urine during the clinical illness, although patients with subclinical disease are also infectious. The virus is spread via oral droplets and is shed in the nasopharynx for approximately 7 days before and after the rash is visible. CRS includes a configuration of anomalies, including nerve deafness, cataracts, cardiac anomalies (usually pulmonary artery and valvular stenosis, and patent ductus arteriosis), and mental retardation, with late complications including diabetes, thyroid disease, growth hormone deficiency, and progressive panencephalitis. In 1969, the first rubella vaccine was licensed for use, and the Centers for Disease Control and Prevention (CDC) began its National Congenital Rubella Syndrome Registry. As required under the National Childhood Injury Act, all healthcare providers in the United States who administer any vaccine shall, prior to administration of the vaccine, provide a copy of the Vaccine Information Statements (VIS) produced by the CDC to the parent or legal representative of any child to whom the provider intends to administer such vaccine, or to any adult to whom the provider intends to administer such vaccine. Despite efforts to vaccinate children, CRS continues to occur in the United States. Hispanic infants have an increased risk of CRS. HIV-1infected children with a preserved immune system and MMR immunization had a good response to rubella vaccine. In contrast, those in more advanced categories for HIV infection responded poorly. Issues of risk, choice, and chance are central to the controversy over the MMR vaccine that erupted in the UK in 1998, and has continued into the new millennium. An important contribution to the MMR controversy has come from the parents of autistic children, some of whom reject the notion that this disorder is a random genetic misfortune and insist that it is, at least in part, the result of some environmental insult, such as MMR vaccinations.

Use of treated woods in roof assembly.

On February 12, 2002, the US Environmental Protection Agency (EPA) announced a voluntary decision by industry to move consumer use of treated lumber products away from a variety of pressure-treated wood that contains Arsenate (As) by December 31, 2003, in favor of new alternative wood preservatives. It is the purpose of this report to outline legislative efforts to ban the use of chromated copper arsenate (CCA)-treated wood for residential roofing in the State of Oregon. At the time that the legislation was introduced, it was coincidental that the National Roofing Contractors Association (NRCA) recommended that CCA-treated wood should not be used in residential roofing. A summary of the report is included in this review. Finally, we discuss some of the potentially harmful environmental hazards of wood preservatives on the environment. In addition to the toxicity of pressure-treated wood on our environment, we point out that wood as well as pressure-treated wood assemblies are highly flammable. Consequently, we recommend the use of residential roofing systems that have Class A fire protection for the homeowner. Because residential roof fires remain a life-threatening danger to residential homeowners in the United States, we describe a national fire prevention program for reducing residential roof fires by use of an Underwriters Laboratories Inc. (UL) and National Fire Protection Association Class A fire-rated roof system.
