超声技术在椎管内麻醉穿刺中的应用进展

超声作为一种可视化技术,在椎管内麻醉穿刺中的应用取得了很大进展。椎管内麻醉是下腹部和下肢手术的常用麻醉方法。超声能够清楚地显示椎管及其周围解剖结构,使椎管内麻醉走向精准化具有重大意义。用超声在椎管内麻醉穿刺前扫描,可预测穿刺的困难程度、定位穿刺点、测量穿刺深度,从而提高椎管内麻醉穿刺的成功率;实时超声引导下椎管内麻醉穿刺能实时地观察穿刺针的角度和深度,使麻醉穿刺全程可见;将超声应用于困难椎管内穿刺及小儿椎管内穿刺,可降低多次穿刺带来的并发症及风险,具有深远的意义。

Application of ultrasound in spinal anesthesia puncture

As a visual technology,ultrasound has made great progress in the application of spinal anesthesia.Spinal anesthesia is a common anesthesia method for lower abdomen and lower limb surgery.Ultrasound can clearly show the spinal canal and its sur-rounding anatomy,which makes great significance to the precision of spinal anesthesia.Scanning before spinal anesthesia with ultra-sound can predict the difficulty of puncture,locate the puncture point and measure the depth of puncture,thereby improving the suc-cess rate of spinal anesthesia,real-time ultrasound guided spinal anesthesia can observe the angle and depth of the needle in real time,which makes the whole process of anesthesia visible,the application of ultrasound to difficult and pediatric spinal puncture can reduce the complications and risks caused by multiple puncture,which has far-reaching significance.
