Abstract:
Objective To investigate the effects of ultrasound-guided continuous thoracic paravertebral nerve block combined with general anesthesia on cardiac function and postoperative complications in elderly patients undergoing thoracotomy.Methods A total of 108 elderly patients who underwent thoracotomy in our hospital from January 2017 to December 2018 were randomly divided into the general anesthesia group(receiving general anesthesia)and the combination group (receiving ultrasound-guided continuous thoracic paravertebral nerve block combined with general anesthesia) (n=54,each group).The anesthesia effect was compared between the two groups.Results The excellence rate of anesthesia was higher in the combination group than in the general anesthesia group(90.7％ vs.72.2％,x2 =4.267,P =0.039).Stroke volume variability(SVV),stroke volume(SV),heart rate(HR) and mean artery pressure(MAP)had no significant difference between the two groups at T0(pre-anesthesia)(P＞0.05).At T1 (anesthesia),T2 (intraoperative tissue traction),and T3(postoperative suture),there were significant differences in SVV,SV,HR and MAP between the two groups(P＜0.05).The incidence of postoperative complications was lower in the combination group than in the general anesthesia group(7.4％ vs.22.2％,x2 =4.696,P=0.000).Conclusions Ultrasound-guided continuous thoracic paravertebral nerve block combined with general anesthesia has good anesthetic effects,minor influence on cardiac function and a low incidence of postoperative complications in elderly patients undergoing thoracotomy.
