ABSTRACT
Combat casualty prediction on the sea is always challenging. Considering various factors involved in the attack and defense of warship formation and missile attack effect, we calculated the combat casualty based on the damage assessment result of combat simulation with reasonable simplification, which provided a forecasting model of combat casualty for surface warship after multiple missile attacks, improving the accuracy of casualty prediction in naval warfare.
ABSTRACT
Objective To investigate the sleep quality and life quality of soldiers in a navy warship troop, and to explore the correlation between sleep quality and life quality and their influencing factors. Methods Random cluster sampling method was used to select navy soldiers from a navy warship troop. The subjects were surveyed by Pittsburgh sleep quality index (PSQI) scale and World Health Organization Quality of Life-Brief scale (WHOQOL-BREF). Results A total of 160 questionnaires were sent out and 154 valid questionnaires were returned (response rate 94.6%). Of 154 subjects, 31.8% (49/154) had good sleep quality, 53.2% (82/154) had moderate sleep quality, and 14.9% (23/154) had poor sleep quality. The soldiers with good sleep quality had significantly higher scores than those with poor sleep quality in physical, psychological, social and environmental domains of life quality (P0.05 or P0.01). Total PSQI score and most of scores of 7 parts of life quality, including subjective sleep quality, sleep latency, sleep time, sleep disturbances, hypnotic drugs, daytime dysfunction and sleep efficiency, were negatively correlated with the scores of 4 domains of sleep quality. There was significant difference in sleep latency of the subjects with the educational level of junior high school, senior high or polytechnic school, junior college, undergraduate college, or graduate degrees (F＝5.368, P0.01), and the subjects with junior college degree had the highest score of sleep latency, while those with undergraduate college degree had the lowest score of sleep latency. Soldiers had a higher score of sleep latency than the officers (t＝2.069, P＝0.040). There was significant difference in the social domain scores of life quality between navy servicemen with military service time 8 years, 3-8 years and ≤2 years (F＝3.401, P＝0.036). Officers had a higher score of social domain than soldiers (t＝－2.093, P＝0.038). Conclusion The sleep quality of navy servicemen should be improved. Improving sleep quality can effectively ameliorate life quality. The sleep quality and life quality of navy servicemen are related to educational levels, work categories and military service time. The corresponding psychological and behavioral intervention should be carried out according to the characteristics of different personnels.
ABSTRACT
In the future,anti-ship missiles(ASM) will be major weapons in the sea war.It is very important to handle the profile of the casualties aboard warships attacked by ASM for development of naval health service.The statistical result shows there is a greater chance of casualties but less chance of warships being sunken by ASM.Besides,medical staffs should pay more attention to the first aid for victims due to blast,burn,smoke inhalation and penetration while the danger of the sea water immersion should not be ignored.
ABSTRACT
Objective To study the method of emergency blood collection during a long-distance voyage to ensure blood transfusion treatment.Methods Ten voluntary blood donors were recruited, a base unit of blood was collected and preserved.Reactions of the blood donors were observed, and the blood quality was tested.Results The success rate of blood collection was 90% and the qualification rate was 100%.Conclusion Emergency blood collection during a long-distance voyage is feasible,which can help ensure blood supply in peace time or war time.
ABSTRACT
Objective To investigate the injury characteristics of Beagle dogs after warship multi cabin explosion.Methods Forty-eight adult male Beagle dogs were placed in the simulated blast-cabin and adjacent cabin (24 each),and ammunitions respectively containing 0.75kg TNT and 3.50kg TNT were then detonated in the blast-cabin.The survival situation,fluctuation of vital signs,morphological changes of organs and the incidence of various types of injury of the dogs were observed immediately after the explosion to 24h after injury,and the neurological functions score was performed.Results Twenty dogs died immediately after the explosion,and another 9 dogs died 24h after the explosion.The total mortality was 60.42％(29/48),and the mortalities in blastcabin and adjacent cabin were 79.17％(19/24) and 41.67％(10/24),respectively.The dog's skull was penetrated by bomb fragments,and congestion and bleeding were observed in brain tissue,lung,heart,stomach,bowels,liver and kidneys.Extremities fracture,soft tissue contusions,perforation and rupture were also checked out after explosion.The fatality rate of bomb fragment injury,blast injury and combined bomb fragment-blast injury was 27.59％(8/29),17.24％(5/29) and 55.17％(16/29),respectively.Conclusions The combined bomb fragment-blast injury show high incidence and make high fatality rate and serious injury.Combatants should effectually shield themselves with occluded objects as far as possible to avoid damage and reduce fatality.The key of early treatment is to treat the multiple injuries promptly.Intravenous fluid therapy should be practiced after hemodynamic monitoring.
ABSTRACT
The hospital ship is an important force in medical support. The normal use of medical equipment is prerequisite for effective clinical work. According to the particularity of nautical work, different ways of fixation and expasion with various medical equipments in the warship are proposed in order to satisfy the needs of clinical work.
