摘要
目的 研究飞行人员胃排空的特点，加强卫勤保障工作。 方法 应用双核素单光子发射计算机体层摄影术（ＳＰＥＣＴ）技术对６４ 例飞行人员和３４ 例同一地区地勤人员进行胃排空检测。 结果 飞行人员组液体胃排空与地勤人员一样均呈指数式排空曲线，两者间无显著性差异（Ｐ＞ ０．０５）；固体食物胃排空，飞行人员组与地勤人员组类似，均呈双相幂指数函数曲线，排空前存在延迟时间Ｔ１，但飞行人员组Ｔ１ 明显缩短，为（３．１±２．８）ｍ ｉｎ，两组间有显著性差异（Ｐ＜ ０．０５）；４０．１％ 的飞行人员Ｔ１ 异常，其中３２．８％ Ｔ１ 消失，７．３％ Ｔ１ 延迟；全胃半排空时间（Ｔ１／２ ）与近端胃半排空时间（ＰＴ１／２）两组间未见明显不同；Ｔ１／２与ＰＴ１／２呈高度相关（ｒ＝ ０．８９，Ｐ＜ ０．０１）；未发现ＰＴ１／２与Ｔ１ 间有相关关系。 结论 飞行人员组固体胃排空障碍可较早地由Ｔ１ 反映出来。
Objective To explore the characteristics ofgastric em ptying in pilots . Methods Sixty four healthy pilots served as subjects, and 34 ground crew ascontrols.Theirgastricem ptying curves w ere obtained using dualisotope-labeled test m eals and single photon em ission com puter to- m ography (SPECT). Results The difference betw een gastric em ptying ofliquid m ealin pilots and controls w as non-significant. As to the gastric em ptying ofsolid m eal, although the difference be- tw een the tw o groups as a w hole w as non-significant, the individualdifferences in pilotgroup w ere im pressive. The gastric em ptying w as accelerated in 14.1% ofpilots, and itw as delayed in 10.1% . In addition, abnorm allag tim e (T1 ) of gastric em ptying of solid m ealw as found in 40.1% ofpilots (T1 disappeared in 32.8% and prolonged in 7.3% ). Conclusions The gastric em ptying of solid m ealin pilots w as influnced by their dietary habit and m ultiple neuro-psychologicalfactors. There- fore, attention should be paid on health care ofdigestive system in pilots.
