ABSTRACT

Objective To evaluate the effect of thoracic paravertebral block ( TPVB) combined with general anesthesia on the long-term quality of life in the patients undergoing breast cancer surgery. Methods A total of 156 patients, aged 18-64 yr, of American Society of Anesthesiologists physical statusⅠ or Ⅱ, undergoing breast cancer surgery, were randomly assigned to TPVB combined with general anes-thesia group (TPVB+GA group, n= 78) and general anesthesia group (GA group, n = 78), and the pa-tients in two groups were matched with a ratio of 1 1. In group TPVB+GA, propofol (target effect-site concentration 2. 5-4. 0 μg∕ml) was given by target-controlled infusion, and patients received either single or multiple injections (T1-T5 ) of TPVB under ultrasound guidance at 30 min before induction of general an-esthesia. Group GA inhaled 2. 0％-2. 5％ sevoflurane. The patients were followed up at 6 and 12 months after operation, postoperative chronic pain and chronic pain affecting daily life were assessed using the mod-ified Brief Pain Inventory, the development of neuropathic pain using neuropathic pain questionnaire-short form, and the development of long-term health-related quality of life by using the 12-item short-form scale. Results There was no significant difference in the incidence of chronic pain and chronic pain affecting dai-ly life, incidence of neuropathic pain or quality of life scale score at 6 and 12 months postoperatively be-tween the two groups (P>0. 05). Conclusion TPVB combined with general anesthesia exerts no effect on the long-term quality of life in the patients undergoing breast cancer surgery.
