长远航期间医院船人员晕船反应情况及其影响因素

目的 调查某次长远航期间医院船人员晕船反应的发生率,并探讨其影响因素.方法 以参与某次长远航的186名医院船人员为研究对象,在长远航结束前采用自制问卷统计其晕船反应发生情况,同时询问随船气象员,统计各个航段平均的浪高及风速,以观察晕船反应的发生与浪高及风速的关系.结果 94名(50.53%)人员发生晕船反应.不同性别、年龄、体质量、居住位置、类别及是否吸烟及坚持体育锻炼的医院船人员,在是否发生晕船反应上的差异均有统计学意义(均P<0.05).晕船反应发生与海浪风速无明显关系,与海浪波高呈线性相关.大部分人员服用或外用药物以缓解症状.结论 晕船反应的发生受多种因素的影响,但人体对风浪可以产生一定的适应能力;任务人员应加强体育锻炼,以进行有效应对.

Seasickness Reaction and Its Influencing Factors of the Hospital Ship Staff during the Long Voyage

Objective To investigate the incidence of seasickness of staff in hospital ship during the long voyage and its influencing factors.Methods A total of 186 health personnel in the hospital ship who participated in the long voyage mission were selected and investigated the occurrence of the seasickness by self-made questionnaire before the end of the duty.At the same time,the weathermen on board were interviewed to count the average wave height and wind speed of each section to observe the relationship among the occurrence of seasickness,wave height and wind speed.Results About 94(50.53%) respondents reported seasickness.There were statistically significant differences in the reaction of seasickness among different genders,ages,body mass,living deck,categories,smoking and physical exercises(all P<0.05).There was no obvious relationship between the occurrence of seasickness and the wave speed,but it was linear with the wave height.Most of the staff took internal or external medicine to relieve symptoms.Conclusions The occurrence of seasickness is affected by many factors,but the human body can have certain adaptability to the wind and waves.The task personnel should strengthen physical exercise,so as to effectively respond to the seasickness.
