Sleep and alertness management is a major point of attention for the medical support of military round the clock operations. Crew's awareness on the effects of fatigue and sleepiness should be enhanced. Flight surgeons should be trained on the use of practical methods to prevent serious fatigue and to enhance performance and alertness of the crew. Although, in civil and in military aviation a considerable number of studies have been conducted on fatigue countermeasures and preventive strategies, results are not readily available for practical use by flight surgeons. In order to develop useful guidelines for flight surgeons and crew, the international aeromedical research community should be able to produce a database on what is already known and identify, areas where knowledge is lacking. In this context research questions related to the use of strategic naps. hypnotics. stimulants, and chronobiotic treatment are put forward.

It was already shown that napping before duty may be a good strategy to prevent performance decline during periods in which the circadian rhythm indicates the need to sleep. However, in a military setting, operational factors may prevent the onset and/or maintenance of restful sleep. In this case the use of hypnotics can be beneficial. Since immediate performance after premature waking can be required in a military setting it is important to choose hypnotics that do not result in so-called post-nap hangovers. In this study, the marmoset monkey model was validated as a model for testing the effects of drugs on performance during time shift work as is the case in many military operations. Subsequently, the effect of hypnotics in the late afternoon on performance during late evening, night and early morning missions was tested. It was proven that the homeostasis in marmoset monkeys after sleep deprivation is similar to the human homeostasis: The sleep intensity after a night of sleep deprivation, which will happen during late night or early morning duty, is increased in the first hours of sleep similar to human. Furthermore, a short nap by these animals before the sleep deprivation period can prevent most detrimental effects on performance and activity, as is the case in humans. Therefore, the marmoset monkey can be considered as a valid model for testing effects of drugs affecting the sleep and alertness behavior.

Flumazenil might be effective to maintain normal performance in case of an alertness demanding situation directly after taking a hypnotic. However, in case personnel have to be alert during a time of the day that the circadian rhythm is programmed for sleep, the use of wake promoting drugs might be more efficient. The alertness enhancer caffeine counteracted the sleep deprivation induced decline on the performance and activity. Modafinil even improved the activity. Chronic use of caffeine or modafinil did not negatively affect the performance and the activity during daytime and resulted in comparable effects as after a single use of these compounds. This means that caffeine and modafinil are both effective in reducing the sleep deprivation induced declines in performance. Moreover, the stimulants remain effective when used in combination with a hypnotic and even after chronic use no worsening of day time performance was observed. Modafinil reach its maximum effect 2-4 hours after oral administration indicating that it can only be used in situation in which the operation is planned by forehand. Caffeine, a fast and short acting compound, should be useful for short scenarios. In case long term improved alertness is needed a slow release administration will be needed.

This article provides a review which addresses the problem of fatigue attributable to sleep loss in modern society and the scientifically proven strategies useful for reducing fatigue-related risks. Fatigue has become pervasive because many people work non-standard schedules, and/or they consistently fail to obtain sufficient sleep. Sleep restriction, sleep deprivation, and circadian desynchronization produce a variety of decrements in cognitive performance as well as an array of occupational and health risks. A number of real-world mishaps have resulted from performance failures associated with operator sleepiness. In some cases, fatigue/sleepiness is unavoidable, at least temporarily, due to job-related or other factors, but in other cases, fatigue/sleepiness results from poor personal choices. Furthermore, some individuals are more vulnerable to the effects of sleep loss than others. Fortunately, fatigue-related risks can be mitigated with scientifically-valid alertness-management strategies. Proper work/rest scheduling and good sleep hygiene are of primary importance. If sleep time is available but sleep is difficult to obtain, sleep-inducing medications and behavioral circadian-adjustment strategies are key. In fatiguing situations such as when sleep opportunities are temporarily inadequate, lin1iting time on tasks, strategic napping, and the potential use of alertness-enhancing compounds must be considered. To optimize any alertness-management program, everyone must first be educated about the nature of the problem and the manner in which accepted remedies should be implemented. In the near future, objective fatigue-detection technologies may contribute substantially to the alleviation of fatigue-related risks in real-world operations.

In this study, the marmoset monkey model was validated using nocturnal electroencephalogram measurements for evaluating effects on sleep quality. In order to test whether the proposed sleep inducing drugs affect the quality of sleep and/or disrupt the normal sleep cycle/architecture, the effects of the short acting hypnotic drugs temazepam, zolpidem and zaleplon on sleep were determined in the marmoset monkey. The results showed that the marmoset monkey model is a valid model for the research of sleep. Furthermore, no large differences between the effects of the tested sleep inducing drugs on the quality of sleep could be observed. All three drugs tended to affect the quality of sleep in a positive way, but also induced some 'rebound-effects'. All drugs, but temazepam especially, resulted in some carry-over effects, - i.e. after awakening animals tended to fall asleep again. On the other hand, after temazepam sleep spindles were observed often. These spindles lower the chance of awakening as a result of sensory input like noise. This was in agreement with the finding that after temazepam less frequent wakening was observed. Furthermore, there some indications that zolpidem has undesired effects in women. This might indicate that for the management of sleep in a military setting the sleep inducing drugs temazepam and zaleplon might both be useful, with the preference for temazepam.
