It has been demonstrated that preparatory ultrasound scanning can facilitate lumbar epidural anesthesia. We compared longitudinal with transverse approach of ultrasound imaging to test the precision and the quality of acquired images in cesar ean delivery patients.
We enrolled 34 cesarean delivery patients. Measured distances from the skin to dura on each ultrasound view was compared with the actual needle depth. Additionally we measured ultrasound visibility score.
The both distances measured in ultrasound strongly correlated with the actual depth (R2= 0.87 and 95% limits of agreement of -3.07 to 6.45 mm on longitudinal view, R2=0.82 and 95% limits of agreement of -3.50 to 7.74 mm on longitudinal view). The visibility score of the longitudinal view was significantly higher than that of transverse view (P<0.01).
Both planes provided accurate information about the epidural space and depth, and the longitudinal plane was superior in the imaging quality. It was suggested that both approaches may help identify epidural spaces.
已证实术前超声扫描可促进腰段硬膜外麻醉。我们比较了超声成像的纵向与横向方法，以测试剖宫产患者所获取图像的准确性和质量。
我们纳入了34例剖宫产患者。将每个超声视图上从皮肤到硬膜的测量距离与实际进针深度进行比较。此外，我们还测量了超声可见度评分。
超声测量的两个距离均与实际深度密切相关（纵向视图上R2 = 0.87，一致性界限为-3.07至6.45 mm，95%；横向视图上R2 = 0.82，一致性界限为-3.50至7.74 mm，95%）。纵向视图的可见度评分显著高于横向视图（P<0.01）。
两个平面均提供了有关硬膜外间隙和深度的准确信息，且纵向平面的成像质量更佳。提示两种方法均可能有助于识别硬膜外间隙。
