 | The Occupational Safety and Health Administration (OSHA) amended 29 CFR Part 1910 in 1991 to include regulations addressing occupational exposure to bloodborne pathogens (BBP). The rule affects all employees who have the potential for occupational exposure to these pathogens. An accident scene presents significant challenges in terms of implementing a program which was primarily envisioned to affect personnel in "traditional" healthcare delivery facilities; the OSHA ... |

| Fatigue occurring during naval air combat can reduce performance, impair operational effectiveness, and compromise safety. This study examines the effect of combat missions on the subjective fatigue of naval aircrews deployed aboard USS AMERICA during Desert Shield and Desert Storm. Fatigue was determined using three questionnaires that were completed before and after each mission. Although fatigue significantly increased during combat missions, it usually returned to preflight levels by the next ... |

| Declining aircrew performance during periods of sustained flight operations (SUSOPs) has underscored the need to develop effective countermeasures. This paper reports on the ability of the central nervous system (CNS) stimulant d-methamphetamine to alleviate the detrimental effects of a simulated SUSOPs on subjective fatigue. Subjective fatigue was repeatedly measured by three questionnaires. The simulated SUSOP started at 1800 and consisted of a 9-h planning session followed by 4 h of ... |

| Sustained flight operations are likely to produce fatigue and performance decrement in aviators. We assessed changes in cognitive performance using a work/rest schedule modeled on successive long-range attack missions. Twelve subjects performed several subtests of the Unified Tri-Service Cognitive Performance Assessment Battery an the Walter Reed Performance Assessment Battery 18 times during a simulated sustained operation. The scenario consisted of a 9- hr planning session followed by a 4-hr rest ... |

| Although substantial literature exists on visual analog scales (VAS), much is directed toward the clinical assessment of pain. As part of a Naval Aerospace Medical Research Laboratory (NAMRL) effort to investigate the chronopharmacokinetics of methamphetamine during simulated sustained flight operations we developed a computerized VAS to determine the intensity of subjective responses associated with the administration of the stimulant. With simple modifications to the program, the questionnaire could be modified ... |

| As part of a sustained fight operations (SUSOPS) research project, we had an opportunity to evaluate the performance of aircrews from three squadrons attached to Carrier Air Wing (CAW) 15. These squadrons were involved in a practice, long-range, overwater, strike mission from the USS CARL VINSON (CVN- 70). At that time, the CARL VINSON was underway from Pearl Harbor, Hawaii, to Alameda, California. The purpose of this investigation was to ... |

| Flight crew fatigue during sustained flight operations (SUSOPS) is an important aeromedical problem. We evaluated the effects of SUSOPS on aircrew stress and fatigue in three U.S. Navy P-3 Orion crews (n = 21) before, during, and after a 6-month overseas deployment. Pre- and postdeployment laboratory tests measured aerobic capacity, pulmonary function, muscular strength and endurance, and resting blood chemistry. Postdeployment lung capacity, blood chemistry values, grip strength, and leg ... |

| Transient insomnia preceding or during intense military aviation operations has, in some cases, been treated by short-acting benzodiazepines like temazepam or triazolam. This study evaluated selected physiological and performance side effects of triazolam (0.25 mg) administered to nine men and one woman. Each subject completed drug and placebo testing, which started at one and eight hours following drug administration. Testing included measures of balance, fine motor movement, two-dimensional tracking, tilt ... |

|
| The bibliographic abstracts in this report are part of a project to assess biomedical effects of chemical warfare antidote agents and related pre- treatment drugs. Specific attention has been focused on the biomedical effects in the following general areas: vision, auditory, spatial orientation, musculoskeletal, cardipulmonary, cognitive performance, pharmacology, cutaneous stimuli, and cortical effects. In some cases, the bibliography addresses other therapeutic drugs that may be used simultaneously with chemical warfare ... |
