The epidemiology of pediatric air medical transports in Utah.

OBJECTIVE: To describe the air-transported patients treated at Primary Children's Medical Center (PCMC), the sole pediatric tertiary care center in Utah and a referral center in the intermountain region. This study describes the patients who utilized the air medical transport system, the medical services provided in the prehospital setting, and the corresponding charges for transport and treatment. METHODS: Participants were air-transported patients aged 17 years and less who were treated at PCMC during the calendar years 1991-1992. The study population excluded patients who were transported to other medical facilities, and newborns. Data were abstracted retrospectively from the patients' medical and transport records. Data collected included demographic information, patient diagnoses, and treatments performed during transport. Financial data were supplied by the hospital. RESULTS: During the study period, 874 pediatric patients met the participant criteria. Helicopter and fixed-wing transports comprised 561 and 313, respectively, from nine states in the mountain and western regions. The majority (313, 56%) of the patients transported by helicopter were trauma patients, while the majority (195, 62%) of fixed-wing transports were for illness-related conditions. Scene transports accounted for 120 (21%) of helicopter transports. Children with special health care needs accounted for 171 (20%) of all transports. CONCLUSIONS: Injury severity scores indicate that, overall, air-transported patients were more severely injured than comparable ground-transported patients. However, it is apparent that some patients who were air-transported could have been transported by ground ambulance without detriment. medical services.

Cytogenetic effects of formaldehyde exposure in students of mortuary science.

The effect of low-level exposure to formaldehyde on oral, nasal, and lymphoycte biological markers was studied prospectively in a group of 29 mortician students who were about to take a course in embalming. During the 85-day study period, the subjects performed an average of 6.9 embalmings and had average cumulative formaldehyde exposures of 14.8 ppm-h, with an average air concentration of 1.4 ppm during embalming. Since the average time spent embalming was 125 min, formaldehyde exposures calculated as an 8-h time-weighted average were 0.33 ppm on days when embalmings were done, which was less than the Occupational Safety and Health Administration permissible exposure limit of 0.75 ppm. Epithelial cells from the buccal area of the mouth showed a 12-fold increase in micronucleus frequency during the study period, from 0.046 +/- 0.17/1000 cells preexposure to 0.60 +/- 1.27/1000 cells at the end of the course (P < 0.05). Nasal epithelial micronuclei increased 22%, from 0.41 +/- 0.52/1000 cells to 0.50 +/- 0.67/1000 cells (P = 0.26). In blood cells, the frequency of micronucleated lymphocytes increased 28%, from 4.95 +/- 1.72/1000 cells to 6.36 +/- 2.03/1000 cells (P < 0.05), while sister chromatid exchanges decreased 7.5% (P < 0.05). A dose-response relationship was observed between cumulative exposure to formaldehyde and increases in buccal micronuclei in the 22 male subjects but not in the 7 female subjects. We conclude that low-level exposure to formaldehyde is associated with cytogenetic changes in epithelial cells of the mouth and in blood lymphocytes. These cytogenetic effects may be useful as markers of biologically effective dose.

Health effects of anesthetic gases.

There are no national regulatory standards from the U.S. Occupational Safety and Health Administration for anesthetic gases. Moreover, there is little data to confirm that current scavenging and exhaust ventilation systems reduce exposure below recommended limits. Operating theater personnel and workers in postanesthesia units are especially at risk.
