摘要 目的:探讨下肢骨科手术应用止血带前后股静脉变化的彩色多普勒超声表现。方法:应用彩色多普勒超声对应用止血带行下肢手术的159例患者于术前、术后7 d进行检查,观察比较手术前后血管内径、血流速度、静脉血栓情况及血管透声性的变化。结果:患者应用止血带前股静脉内径(10.70±0.42)mm,血液流速(20.76±1.24)cm/s,术后股静脉内径(10.42±0.35)mm,流速(20.59±1.27)cm/s。静脉血栓形成12例(术前2例,术后10例),血管透声差65例(术前21例,术后44例),血液呈明显云雾状向心性方向缓慢移动。患者应用止血带前后的股静脉内径、流速差异无统计学意义,但静脉血栓人数、血管透声情况减低差异有统计学意义(P<0.05)。结论:下肢骨科手术应用止血带对患者股静脉内径、静脉血流速度影响不明显,静脉血栓形成和血管透声情况可能是因手术后患者卧床少动导致血液黏稠度增加而影响,需经进一步对照研究验证其存在与否及影响程度。
