目的探讨改良后穿刺活检方法在减少穿刺孔出血中的作用。方法成年家兔30只,对左侧胫骨采用传统骨穿刺活检方法;对右侧胫骨采用改良后骨穿刺活检方法,并于穿刺后应用套管植入密封栓封堵穿刺孔。彩超评定穿刺孔出血发生情况。结果 30只家兔穿刺后30min彩超检查结果显示,左侧胫骨穿刺孔周围有不同程度出血27只(90%),血肿直径≤5mm 7例,>5mm 20例;右侧胫骨穿刺孔周围有出血3只(10%),血肿直径均≤5mm;右侧胫骨穿刺孔出血率明显低于左侧胫骨,差异有统计学意义(P<0.05)。结论改良后骨穿刺活检技术可减少穿刺孔出血。
Objective To investigate the effect of modified biopsy on reducing bleeding in puncture holes. Methods Thirty adult rabbits were divided into two groups: the conventional tibia biopsy was performed on the left tibia, the modified biopsy was performed on the tibia on the right, and the perforation was performed after the puncture. Color Doppler ultrasound puncture bleeding. Results 30 rabbits puncture 30min after color Doppler ultrasound examination showed that the left tibia puncture around the hemorrhage with varying degrees of 27 (90%), hematoma diameter ≤ 5mm in 7 cases,> 5mm in 20 cases; right tibial puncture around the bleeding 3 (10%), hematoma diameter ≤ 5mm; right tibial puncture bleeding rate was significantly lower than the left tibia, the difference was statistically significant (P <0.05). Conclusion Improved bone biopsy can reduce the puncture hole bleeding.
