目的 探讨生理盐水脉冲式灌洗对椎体成形术中骨水泥分布、注射压力、外渗的影响.方法 选用40个防624D腐标本椎体,经处理后制备成压缩骨折模型.将其随机均分成两组,实验组在进行椎体成形术之前,运用200 ml生理盐水脉冲式灌洗椎体,对照组不进行灌洗.所有样本都将3ml中黏度骨水泥注入椎体,同时对注射压力、骨水泥的分布和外渗进行测定.结果 应用K-W检验对两组注射压力进行比较,显示:对照组压力60％在100N以上,而实验组仅15％在100N以上,差异有统计学意义(P＜0.05)；骨水泥分布,CT显示:实验组分布更加均匀；骨水泥外渗:对照组为40％ (8/20)椎体出现外渗,而实验组为15％ (3/20).结论 在椎体成形术中,预先应用生理盐水脉冲式灌洗,可以使骨水泥分布更加均匀,同时降低了骨水泥外渗及肺栓塞的发生率,使骨水泥注入更加安全.
目的 探討生理鹽水脈遲式灌洗對椎體成形術中骨水泥分佈、註射壓力、外滲的影響.方法 選用40箇防624D腐標本椎體,經處理後製備成壓縮骨摺模型.將其隨機均分成兩組,實驗組在進行椎體成形術之前,運用200 ml生理鹽水脈遲式灌洗椎體,對照組不進行灌洗.所有樣本都將3ml中黏度骨水泥註入椎體,同時對註射壓力、骨水泥的分佈和外滲進行測定.結果 應用K-W檢驗對兩組註射壓力進行比較,顯示:對照組壓力60％在100N以上,而實驗組僅15％在100N以上,差異有統計學意義(P＜0.05)；骨水泥分佈,CT顯示:實驗組分佈更加均勻；骨水泥外滲:對照組為40％ (8/20)椎體齣現外滲,而實驗組為15％ (3/20).結論 在椎體成形術中,預先應用生理鹽水脈遲式灌洗,可以使骨水泥分佈更加均勻,同時降低瞭骨水泥外滲及肺栓塞的髮生率,使骨水泥註入更加安全.

Objective To investigate the effect of the pulsed lavage on the injection pressure and the distribution and the leakage of bone cement for the vertebroplasty.Methods The compression fracture was modeled on forty embalmed verteboral body that were divided into the control group and the experimental group.3 ml medium viscosity bone cement was infused into all the vertebral bodies and the pulsed lavage was used before the injection of bone comment on the experimental group.The injection force,distribution and leakage of bone cement were exmanined.Results All the normal saline was recycled due to the application of negative pressure devices.K-W test was used for the comparison between the experimental group and the control group.It was shown that the injection pressure of bone cement with more than 100 N was 60％ and 15％ in the control group and the experimental group,respectively.P ＜0.05 was considered significantly different.The CT result showed that the distribution of bone cement was more well-distributed,The rate of extravasation was 40％ (8/20) and 15％ (3/20) in the control group and the experimental group,respectively.Conclusion The pulsed lavage is benefit to the uniform distribution of bone comment and reduce the leakage of bone cement and the the incidence of pulmonary embolism for vertebroplasty.
