Biomechanical performance of cutting edge surgical needles.

The purpose of this study was to compare the biomechanical performance of cutting edge needles made of S45500 stainless steel alloy to Surgalloy stainless steel. The new high-nickel stainless steel alloy, Surgalloy, has superior performance characteristics over that of the other high-nickel stainless steel alloy, S45500. The Surgalloy needle is produced from a stronger stainless steel alloy than the S45500 needle. The Surgalloy needle has considerably greater resistance to bending than the needle produced from S45500 alloy. In addition, Surgalloy stainless steel has almost a twofold greater resistance to fracture than the S45500 stainless steel alloy.

Magnetic resonance imaging in the early diagnosis of group A beta streptococcal necrotizing fasciitis: a case report.

Early diagnosis of invasive group A beta streptococcal (GABS) infection has been achieved in a patient using magnetic resonance imaging (MRI) complemented by needle aspiration. Life-saving treatments of GABS infection that include immediate surgical debridement along with the administration of i.v. antibiotics, gamma globulin, and hyperbaric oxygen were then implemented successfully to prevent the development of streptococcal toxic shock syndrome. While MRI is valuable in making early diagnosis of GABS, it should not delay surgical intervention.

Inadequate standard for glove puncture resistance: allows production of gloves with limited puncture resistance.

The National Fire Protection Association has developed standards for glove puncture resistance using a metal puncture probe. Biomechanical performance studies have demonstrated that glove puncture resistance to the probe is significantly greater than that of the hypodermic needle, suggesting that these standards have no clinical relevance. These standards give a false sense of security to health care personnel and sanction the production and use of gloves that give inadequate protection. The result is potentially harmful for medical personnel.

Balcony collapse at the University of Virginia graduation: what hath Jefferson wrought?

The purpose of this report is to describe the emergency medical response to a disaster caused by the collapse of a balcony in Pavilion I on the Lawn of the University of Virginia during graduation. The emergency medical response to rescue of the injured was hindered by five major factors: (1) a metal linked chain blocked access of rescue vehicles, (2) inability to identify an emergency medical command officer, (3) failure to transfer injured patients with stable vital signs and secured to backboards to a triage area away from the scene of the accident, (4) ineffective crowd control, and (5) the failure to delay procession until completion of patient transport from the disaster site. Sixteen people were injured in the accident and one patient died. The cause of the accident was the absence of a redundant architectural support system for the balcony.

Does the architectural design of burn centers comply with the Americans with Disabilities Act?

Title III of the Americans with Disabilities Act (ADA) requires that hospitals and burn centers be designed and constructed so that all public and common-use areas are accessible. At least 10% of patient bedrooms and toilets must be accessible to persons with mobility disorders. The purpose of this study was to determine whether four hospitals with burn centers complied with Title III of the ADA. The burn centers agreed to participate in this study only if they were first assured anonymity, because of the Health Care Financing Administration of the U.S. Department of Health and Human Services requires that each hospital comply. With use of the ADA accessibility guidelines, we developed a survey instrument that was validated by a state government building inspector. This tool was used to inspect the burn center facility and common use areas in four hospitals with burn centers. In the four hospitals, numerous architectural barriers to persons with disabilities were noted. No burn center had a designated accessible room for persons with disabilities. The bedrooms, bathrooms, sinks, bathtubs, and toilets were not accessible to persons with disabilities. The common-use areas in the hospitals, in contrast, had few architectural barriers to persons with disabilities. Only one burn center had plans to eliminate architectural barriers in its hospital. Because the four hospitals with burn centers had numerous architectural barriers for persons with disabilities, it can be concluded they do not comply with Title III of the ADA and are subject to severe penalty from the Health Care Financing Administration and the U.S. Department of Justice.

A new barrier-free burn center.

This article describes a barrier-free burn center that is accessible to persons with disabilities and that complies with Title III of the Americans with Disabilities Act. The burn center has 3 separate components: patient rooms, patient support facilities, and staff support facilities. Thirteen rooms are used to care for 16 patients. Two of the 13 rooms are accessible to people with disabilities. These 2 rooms have wide doors that permit a wheelchair to pass through, and they have enough clear floor space for a wheelchair to make a 180 degrees turn. The rooms have a sink that is accessible from a wheelchair. The bathrooms have large, clear floor spaces that allow for the turning of a wheelchair, elevated toilets, grab bars, and showers that permit wheelchair access. Special wheelchairs that provide easier shower and commode access are available. The patient support services feature a large hydrotherapy room that contains a table-shower system that allows a person in a wheelchair to gain access to both sides of the shower table. A tub room has been constructed to provide compact patient bathing and hydromassage, and it is also accessible to people in wheelchairs. The staff support services include a locker room that has a shower accessible to people with disabilities so that staff members with mobility disorders can work in the burn center. Grade II braille writing marks all of the signs that designate the permanent rooms and spacing in the burn center and in the contiguous common use areas. The common use area has a restroom accessible to people with disabilities and a waiting room with a telephone communications system for people with mobility disorders or mobility impairment.

New assistive technology for passive standing.

The anesthetic skin of patients with spinal cord injuries makes these patients a high-risk population for burn injuries. Innovations in rehabilitation engineering can now provide the disabled with mechanical devices that allow for passive standing. Passive standing has been shown to counteract many of the effects of chronic immobilization and spinal cord injury, including bone demineralization, urinary calculi, cardiovascular instability, and reduced joint range of motion and muscular tone. This article will describe several unique assistive devices that allow for passive standing and an improvement in daily living for people with disabilities.
