We investigated the value of using contrast as an additional aid to confirm the accuracy of needle placement for caudal epidural injections under intraoperative image intensifier guidance.
A total of 252 consecutive patients were included in this study. Their mean age was 46.7 years (range, 32 to 76 years). There were 133 males (53%) and 119 females (47%) over a 12-month period.
Of the 252 consecutive procedures, the contrast enhanced image intensifier confirmed accurate needle placement on first attempt in 252 cases (100%). Needle resiting following the infiltration of contrast was required in 0 case.
The results from this study demonstrate that a surgeon beyond the learning curve can accurately place caudal epidural injections using image intensification only, without the use of contrast.
我们研究了在术中影像增强器引导下，使用造影剂作为辅助手段来确认骶管硬膜外注射时针头位置准确性的价值。
本研究共纳入252例连续患者。他们的平均年龄为46.7岁（范围32至76岁）。在12个月期间，有133名男性（53%）和119名女性（47%）。
在252例连续操作中，造影剂增强的影像增强器确认首次尝试时针头位置准确的有252例（100%）。0例需要在注入造影剂后重新调整针头位置。
本研究结果表明，处于学习曲线之外的外科医生仅使用影像增强技术即可准确进行骶管硬膜外注射，无需使用造影剂。
