目的 对患有非溃疡性消化不良的飞行人员进行胃排空功能检测。 方法 采用双核素标记试餐及单光子发射计算机体层摄影 (SPECT)技术 ,对 5 4例非溃疡性消化不良 (NUD)飞行员(其中包括类溃疡型 2 3例 ,运动障碍型 2 6例 ,返流型 5例 )和 6 4例健康飞行员进行胃排空测定 ,求出各自全胃半排空时间 (T1 /2 ) ,近端胃半排空时间 (PT1 /2 ) ,固体食物开始排空前的延迟时间 (T1 )及其异常的发生率。 结果 与对照组相比 ,NU D组飞行员液体 T1 /2 延长 ,与 3型 NU D间均无明显关系 ;固体 T1 /2 明显延长 ,异常发生率 72 .2 % ,与运动障碍型 NUD和返流型 NU D呈正相关 (r=0 .81和 0 .78,P<0 .0 5 ) ;PT1 /2 与类溃疡型 NUD呈正相关 (r=0 .75 ,P<0 .0 5 ) ;T1 异常发生率 88.9% ,其中38.2 %延迟 ,与运动障碍型 NU D呈正相关 (r=0 .78,P<0 .0 5 ) ,另 6 1.8% T1 消失 ,与类溃疡型 NU D呈负相关 (r=- 0 .6 7,P<0 .0 5 )。 结论 NUD飞行员多有固体食物排空障碍。
Objective To test the gastric emptying function of pilots with non-ulcer dyspepsia. Methods A total of 54 non-ulcer dyspepsia (NUD) pilots (including 23 cases of ulcer-like type, 26 cases of dyskinesia type, (N = 5) and 6 healthy pilots (n = 6) were tested for gastric emptying, and their full gastric partial emptying time (T1 / 2), proximal gastric emptying time (PT1 / 2) Unprecedented delay time (T1) and its incidence of abnormalities. Results Compared with the control group, the fluid T1 / 2 in NU D pilots was prolonged and had no significant relationship with type NU NU 3. The solid T1 / 2 prolonged significantly with an abnormality rate of 72.2% There was a positive correlation between flow pattern NU D (r = 0.81 and 0.78, P <0.05); PT1 / 2 was positively correlated with type NUD (r = 0.75, P <0.05); The incidence of T1 abnormalities was 88.9%, of which 38.2% was delayed, positively correlated with dyskinesia NU D (r = 0.78, P <0.05) and 6 1.8% T1 disappeared, which was negative with type NUU (R = - 0.676, P <0.05). Conclusion NUD pilots have more solid food emptying obstacles.
