针刺鸠尾穴安全角度和深度的探讨

目的:观测针刺鸠尾穴的安全角度与深度,为临床安全针刺该穴提供参考数据。方法:选取健康成年男女各10名,运用MRI对鸠尾穴进行扫描获得图像,得出安全角度和安全深度并与身高、体质量、体质量指数(BMI)、乳间距和拇指同身寸进行相关性分析。结果:水平向右和向左针刺的最小危险角度男女之间无差异;以选定的测量角度针刺时的危险深度男女之间无差异;各个方向针刺的安全深度:直刺为(16.99±2.86)mm,向下45°为(22.72±5.35)mm,向上45°为(24.61±2.92)mm,向下15°为(53.47±5.72)mm,向上15°为(25.76±2.61)mm,向右45°为(24.89±4.34)mm,向左45°为(21.79±3.84)mm,向右以最小危险角度针刺为(51.19±2.69)mm,向左以最小危险角度针刺为(51.86±2.59)mm;水平向右和向左针刺的最小危险角度,直刺、向下45°、向右45°和向左45°以及向右和向左以最小危险角度针刺的危险深度与BMI存在相关性;直刺、向下45°和向下15°针刺的危险深度与体质量存在相关性。结论:水平向右和向左针刺时需依据BMI确定最小危险角度;以选定的测量角度针刺时不需区分性别选择针刺深度;直刺、向下45°和向下15°针刺时应参考体质量选择针刺深度;直刺、向下45°、向右和向左45°、向右和向左以最小危险角度针刺时应参考BMI选择针刺深度。

Discussion on the safe angle and depth of acupuncture at Jiuwei (CV 15)

Objective To observe the safe angle and depth of acupuncture at Jiuwei(CV 15) so that the referen-ce data can be provided for the clinical safe acupuncture at the point.Methods Ten healthy adults of either sex were selected.MRI was applied to scan Jiuwei(CV 15) and obtain the images.The safe angle and depth were collected for the correlative analysis with the body height,body mass,body mass index(BMI),nipple distance and the finger measurement considered.Results There was no difference in the minimal dangerous angle of the horizontal needling to the right and the left between the male and the female.There was no difference in the dangerous depth of needling under the designed angle of needling between the male and the female.The safe depth of needling to the different directions:(16.99±2.86)mm for perpendicular needling,(22.72±5.35)mm for 45° downward needling,(24.61±2.92)mm for 45° upward needling,(53.47±5.72)mm for 15° downward needling,(25.76±2.61)mm for 15° upward needling,(24.89±4.34)mm for 45° needling to the right,(21.79±3.84)mm for 45° needling to the left,(51.19±2.69)mm for the needling at the minimal dangerous angle to the right,(51.86±2.59)mm for the needling at the minimal dangerous angle to the left.BMI was correlated to the minimal dangerous angle of the horizontal needling to either the right or the left,perpendicular needling,45° downward needling,45° needling to the right and 45° needling to the left,as well as to the dangerous depth of needling at the minimal dangerous angle to either the right or the left.The body mass was relevant with the dangerous depth of perpendicular needling,45° downward needling and 15° downward needling.Conclusion For the horizontal needling to the right or the left,the minimal dangerous angle should be determined in reference to BMI.For the angle of needling mea-sured in advance,the needling depth is not required to be identified in light of the sex.For the perpendicular needling,45° downward needling and 15° downward needling,the needling depth should be optioned in accordance with the body mass.For the perpendicular needling,45° downward needling,45° needling to the right or to the left,as well as the needling at the minimal dangerous angle to either the right or the left,the needling depth should be determined in terms of BMI.
