摘要
目的 探讨病程长短对积液量、胸膜厚度、抽液难度的影响 ,以及测量距体表深度与实际进针深度的关系。方法 76例结核性胸腔积液患者根据病程分为 3组 :A组 (病程≤ 1个月 )、B组 (1个月 <病程 <3个月 )、C组 (病程≥ 3个月 ) ,在 B超引导下穿刺 ,测量穿刺前后暗区深度、抽出液体量、胸膜厚度、距体表深度与实际进针深度。结果 3组病例穿刺前暗区深度无明显差异 (P>0 .0 5 ) ;穿刺后暗区深度 A组小于 B组和 C组 (P<0 .0 5 ) ,B组与 C组无明显差异 (P>0 .0 5 ) ;抽出量 A组与 B组无明显差异 (P>0 .0 5 ) ,A组和 B组大于 C组 (P<0 .0 5 ) ;距体表深度、胸膜厚度以及进针深度 A组小于 B组 (P<0 .0 5 ) ,B组小于 C组 (P<0 .0 5 )。 3组病例 B超测量距体表深度均小于实际进针深度 (P<0 .0 5 ) ,当 B超测量深度均加 5 mm后 ,B超测量与实际深度无明显差异 (P>0 .0 5 ) ,且有显著相关性 (r=0 .97)。结论 病程与积液量无关 ,病程越长胸膜越厚 ,液体距体表越深、抽出液体的难度越大 ,测量距体表深度加 5 mm能准确估计进针深度。
Objective To explore the influence of clnical course to thoracic effusion quantity,pleura thickness and difficulty of drawing liquid,and the relation between the distance measured with ultrasound and actual depth.Methods 76 cases divided into three groups according to clinical course.group A(≤1 month),group B(<3months and >1 month),group C(≥3 months).Thoracentesis was guided through ultrasound and the depth of hydrothorax,drawn liquid quantity,pleurs thickness,the distance away from body surface and actual depth confirmed by thoracentesis was measured.Results The difference of depth before thoracentesis among three groups were not considered significant(P> 0.05) ,the depth after thoracentesis group A is smaller in contrast with group B and group C(P<0.05),but there is no significant difference between group B and group C(P>0.05);And there is no significant difference of drawn liquid quantity between group A and group B(P>0.05),the quantity both group A and group B are greater in contrast with group C(P<0.05);In terms of distance away from body surface,pleura thickness,and actual depth through thoracentesis,group A is smaller than group B(P<0.05),group B is smaller than group C(P<0.05);the distance away from body surface measured with ultrasound is smaller than actual depth confirmed by thoracentesis in all the three groups(P<0.05),when each distance measured with ultrasound adds 5mm,the data have no significant difference in contrast with actual depth(P>0.05),and they have significant correlativity(r=0.97).Conclusions There is no relation between thoracic effusion quantity and clinical course;the longer the clinical course,the thicker the pleura,the more distant the liquid away from body surface,the more difficult the liquid drawn from the pleural cavity;Distance from body surface added 5mm can evaluate accurately the actual depth.
