Adequate pain control following thoracic surgery is important to enhance post-operative recovery. Paravertebral catheters have been reported to have a variety of clinical applications, including the blunting of surgical pain, lessening the need for opioids, and improvement in post-operative ventilation. The spread of local anesthesia to multiple paravertebral spaces is needed to establish an effective block. We have determined that the spread of contrast dye by a catheter in the thoracic paravertebral space is greater in a programmed intermittent bolus than in a continuous basal infusion.
胸外科手术后充分的疼痛控制对于促进术后恢复很重要。据报道，椎旁导管有多种临床应用，包括减轻手术疼痛、减少阿片类药物的使用以及改善术后通气。需要将局部麻醉药扩散到多个椎旁间隙以建立有效的阻滞。我们已经确定，在胸椎旁间隙中，导管注入造影剂时，程序间歇性推注比持续基础输注的扩散范围更大。
