目的 了解潜水员脑血流改变和神经心理学变化的关系。方法 38名潜水员和 38名作为正常对照的护卫舰人员分别被分为潜水员组和对照组 ,两组人员均接受经颅多普勒 (TCD)检查和康奈尔医学指数测量。结果 潜水员组的峰值平均血流速度 (Vm) (6 8.12± 11.2 3) cm/s和阻力指数 (RI)(0 .6 1± 0 .0 1)明显高于对照组 Vm(5 5 .2 5± 10 .2 1) cm/s和 RI(0 .5 3± 0 .0 2 ) (P<0 .0 1)。潜水员组的 M-R评分 (9.0 0± 1.75 )分明显高于对照组 (5 .0 5± 1.43)分 (P<0 .0 1)。潜水员组的 M- R评分与 Vm、RI相关系数分别为 r1 =0 .6 5 0 7和 r2 =0 .6 40 3,有明显相关性 (P<0 .0 1)。结论 潜水员神经心理学改变与其相应的脑血流减低有关。
Objective To understand the relationship between changes of cerebral blood flow and neuropsychology in divers. Methods Thirty-eight divers and 38 normal-control frigate personnel were divided into two groups: the diver group and the control group. Both groups received transcranial Doppler (TCD) and Cornell Medical Indexes. Results The peak mean blood flow velocity (Vm) (6 8.12 ± 11.2 3) cm / s and resistance index (RI) (0.61 ± 0. 01) in the diver group were significantly higher than those in the control group Vm 5 ± 10 .2 1) cm / s and RI (0 .5 ± 0 .0 2) (P <0.01). The diver’s M-R score (9.0 ± 1.75) was significantly higher than that of the control group (5.50 ± 1.43) (P <0.01). The correlation coefficient between M-R score and Vm, RI of the diver group was r1 = 0.6570 and r2 = 0.64403, respectively (P <0.01). Conclusion Diver’s neuropsychological changes are related to their corresponding reduction of cerebral blood flow.
