摘要
目的观察椎旁间隙阻滞用于开胸术后的镇痛效果及对血流动力学的影响。方法门例单侧开胸手术病人，术前经皮行胸椎旁间隙穿刺置管，注人０．５％布比卡因１５ｍｌ，观察血压、心率变化，术后间断注人０．５％布比卡因镇痛。结果椎旁间隙阻滞对血压，心率无明显影响，阻滞范围为Ｔ３～Ｔ８，术后８例病人带管回病房，６例出现切口中度疼痛的时间平均为（７．５±６．２）ｈ，再次椎旁间隙注射０．５％布比卡因１５ｍｌ后切口疼痛均缓解或完全消失。未出现恶心、呕吐及局麻药中毒症状。结论椎旁间隙阻滞操作简单，术后镇痛完善，不影响隔肌运动，适用于开胸手术的术后镇痛。
Objective To observe the effect of paravertebral block on hemodynamics and pain relief after thoracotomy. Methods Twelve patients underwent unilateral thoracotomy were inserted a catheter intO paravertebral space. The changes of wterial pressure and heart rate were observed and measured after a dose of 15 ml 0.5% bupivacaine was given. Postoperative analgesia were done by injection of 0.5% bupivacaine. Results There were no significant changes in anerial pressure and beau rate after injection of bupivacaine. Five dermatomes of intercostal nerve block were achieved and 8 patients were sent back to the ward with the catheter.Of the 8 patients, 6 had moderate pain for (7.5 ±6.2) h postoperation and complete pain relief were got by interrupted injection of bupivacaine. No nausea vomitting and symptoms or signs of local anesthetic toxicity were found. Conclusion Paravertebral block technique is easy to perform and could give perfect analgesia after thoracotomy without influence on diaphragmatic movement.
