应用MRI测量大包穴针刺深度的研究

On Needling Depth of Dabao Acupoint with MRI

目的:研究大包穴在MRI定位下的针刺安全深度,为针灸临床医生提供安全进针的参考数据,减少针刺意外。方法:选择身体健康志愿者男女各10人。MRI扫描通过大包穴体表标记点层面,在MRI图像上测量大包穴到壁层胸膜直刺深度。结果:男组危险深度左侧(20.47±2.61)mm、右侧(21.05±2.82)mm,安全深度:左侧(15.36±1.96)mm、右侧(15.79±2.11)mm;女组危险深度:左侧(18.33±3.27)mm、右侧(18.92±4.64)mm,安全深度:左侧(13.75±2.46)mm、右侧(14.19±3.48)mm。针刺危险深度性别差异比较P﹥0.05,说明无明显差异;双侧差异性比较P﹥0.05,说明无明显差异。结论:大包穴针刺危险深度:左侧(19.40±2.98)mm、右侧(19.98±3.89)mm;安全深度:左侧(14.55±2.31)mm、右侧(14.98±2.93)mm。MRI检查为穴位针刺深度的研究提供了更安全、精确的研究方法。

Objective：To study the secure depths of acupuncture points with MRI technique so as to provide the security reference data for clinicians in acupuncture treatment,then to reduce needle stick injuries. Methods：Ten healthy adult male and ten healthy adult women were selected as volunteers.The needling depth can be obtained through measuring vertical distance from Dabao acupoint marked point to parietal pleura on MRI image. Results：1.Men＇s vertical dangerous depth： left side：（20.47±2.61）mm and right side：（21.05±2.82）mm,safe depth（L： 15.36±1.96）mm and R：（15.79±2.11）mm;Woman＇s vertical dangerous depth：L：（18.33±3.27）mm and R：（18.92±4.64）mm,safe depth L：（13.75±2.46）mm and R：（14.19±3.48）mm.2.The discrepancy of dangerous needle depth between man and women：1） Gender difference P0.05,which shows no significant difference 2） Compare left and right side P0.05,which shows no significant difference. Conclusion：Needling depth of Dabao acupoint：the dangerous depth L ：（19.40 2.98）mm and R：（19.98 3.89）mm;The safety depth L：（14.55±2.31）mm and R：（14.98±2.93）mm.MRI provides a more secure and accurate research method for needling depth in clinic.
