RÉSUMÉ
From January 2016 to June 2017, 68 patients with thoracic osteoporotic compression fractures were treated with percutaneous kyphoplasty, including 31 cases with ultrasound-guided thoracic paravertebral nerve block (group A) and 37 cases with local anesthesia (group B). The duration of analgesia in group A was longer than that in group B (P<0.05). The satisfaction of anesthesia in group A was higher than that in group B (90% vs. 68%, P<0.05). There was no significant difference in length of hospital stay and cost between the two groups (P>0.05). The post-operative VAS scores was significantly lower than those of pre-operation in both groups (P<0.05). The intraoperative VAS score of group A was lower than that of group B (P<0.05). There was no significant difference between the two groups in mean arterial pressure and heart rate (P>0.05). No cardiovascular and cerebrovascular adverse reactions occurred in both groups. Ultrasound-guided thoracic paravertebral nerve block is a safe and effective method used in percutaneous kyphoplasty.
