[Proven and unproven hygiene measures in orthopedics].

Postoperative wound infections develop in approximately 2-5% of all patients after orthopedic surgery. After urinary tract infection and pneumonia, such wound infections (15%) are the third most frequent type of hospital-acquired infection. In this review we summarize all proven and unproven hygiene measures available in orthopedics, giving special attention to those implemented with the aim of preventing and controlling postoperative wound infections. Routine application only of hygiene procedures of proven efficacy will be an important contribution to economic and ecological quality assurance in hospital.

Protective equipment for health care facility decontamination personnel: regulations, risks, and recommendations.

After recent terrorist attacks, new attention has been focused on health care facility decontamination practices. This article reviews core issues related to the selection of appropriate personal protective equipment for health care facility decontamination personnel, with an emphasis on respiratory protection. Existing federal regulations focus primarily on scene response and not on issues specific to health care facility decontamination practices. Review of existing databases, relevant published literature, and individual case reports reveal some provider health risks, especially when the exposure involves organophosphate agents. However, reported risks from secondary exposure to contaminated patients at health care facilities are low. These risks should be adequately addressed with Level C personal protective equipment, including air-purifying respirator technologies, unless the facility determines that specific local threats require increased levels of protection.

[The "high concentration" oxygen mask: a dangerous defect].

Three cases of unidirectional valve inversion in airtight oxygen masks are reported. These defects were discovered before use on a patient. One of the masks was tested on a healthy volunteer. It resulted in the rupture of the reservoir bag, with a oxygen leak and decrease in FiO2. Checking the valve before use is therefore mandatory, and fabrication procedures should be revised.

Personal protective equipment in helicopter EMS.

For a variety of reasons, air medical crews continue to be exposed to situations that can bring about severe personal injury or death. Despite recommendations from the Federal Aviation Administration and the Association of Air Medical Services, the use of personal protective equipment among air medical crews is not uniform or universal. Helmets have been shown to decrease morbidity and mortality from head injury, the most common form of injury in a helicopter crash. Flame-retardant clothing may likewise improve the outcome of an in-flight or post-crash fire and should include gloves. Additional consideration should be given to the appropriate undergarments. Protective footwear can also decrease injuries to air medical crews.

The efficiency of protective hoods used by sandblasters to reduce silica dust exposure.

Several types of respiratory protective hoods used by sandblasters were investigated in two steel fabrication yards. MSA Gravimetric Dust Samplers were used to collect respirable dust samples outside and inside hoods during sandblasting. Colorimetric and x-ray diffraction techniques were applied to the samples for free-silica determination. The majority of the sandblasters, who wore various types of air-supplied hoods, were exposed to an average level of silica dust several times higher than the TLV. Sandblasters wearing non-air-supplied hoods were at the greatest risk. Modern well maintained and properly worn air-supplied hoods offered fair protection during sandblasting periods, but the concentration of suspended respirable dust in ambient air during non-blasting intervals exceeded the TLV by several times.

Respirator compensation of a portable air monitor.

A respirator-compensated, portable air-monitor has been devised by modifying a commercially available personal air sampling pump. A switching circuit box, integrated into the sampling pump electrical system and activated by a micro switch mounted within the respirator mask, turns the pump off and a timer on whenever the respirator is worn. Thus, valid measurements of an individual worker's environmental exposures can be made even though that worker uses a respirator at his own discretion.
