Abstract:
Objective To investigate the safety and effectiveness of thoracic paravertebral nerve block on radiofrequency ablation of liver tumors. Methods A total of 40 patients underwent radiofrequency ablation of liver tumor, were ran-domly divided into target-controlled infusion group(group G,n=20)and paravertebral nerve block group (group P,n=20). The intraoperative vital signs, anesthesia effects,anesthesia work time, total operation time,postanesthesia care unit stay time, major adverse clinical events and postoperative VAS scores of two groups were recorded and compared. Results The anesthesia satisfactory rate of G group was 95% and P group was 100%. After anesthesia induction MAP,HR,SPO2 and R declined significantly in group G. Compared with group G,intraoperative vital signs were more stable in group P. Major adverse clinical events in group P were less than group G (P<0.05). The effecting time in group P was longer than group G. The postanesthesia care unit stay time was longer in group G than group P(P<0.05). The post-operative VAS scores in group P declined much more than those in group G before 24 hours postoperatively(P<0.05). Conclusion Thoracic paravertebral nerve block for anesthesia in liver tumors underwent radiofrequency ablation is safe and effective.
