Abstract:
Objective To evaluate the effect of thoracic paravertebral block ( TPVB) combined with general anesthesia on early postoperative recovery in patients undergoing breast cancer surgery. Meth-ods A total of 201 patients with untreated primary breast cancer, aged 18-69 yr, with body mass in-dex <35 kg∕m2 , of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, scheduled for elective surgery for treatment, were enrolled and randomly assigned to general anesthesia group (group GA, n =102) and TPVB combined with general anesthesia group (group TGA, n= 99). In group TGA, TPVB was performed under ultrasound guidance at 30 min before surgery, and 0. 75％ ropivacaine 5 ml was injected at each puncture site of T1-5 . In group GA, local infiltration anesthesia was performed with 1％ lidocaine 0. 2 ml at each puncture site. Anesthesia was induced with IV fentanyl, propofol and rocuronium in both groups. Anesthesia was maintained by inhaling sevoflurane ( group GA), target-controlled infusion of propofol (group TGA) and intermittent IV boluses of fentanyl or rocuronium. Bispectral index value was maintained at 40-60 during surgery. Verbal Rating Scale score was used to assess the severity of pain after surgery. Parecoxib sodium 40 mg, pethidine 50 mg, tramadol 50 mg or fentanyl 50 μg was selected and intrave-nously injected as rescue analgesics when Verbal Rating Scale pain score>4. The requirement for rescue analgesia and development of nausea and retching∕vomiting were recorded within 2 days after surgery. Chinese quality of recovery score was used to assess the early postoperative quality of recovery on days 1 and 2 after surgery. Results Compared with group GA, the quality of recovery score was significantly increased on days 1 and 2 after surgery, the incidence of postoperative nausea was decreased (P<0. 05), and no signifi-cant change was found in the requirement for rescue analgesia or incidence of retching∕vomiting after surgery in group TGA (P>0. 05). Conclusion TPVB combined with general anesthesia is more helpful than gen-eral anesthesia alone for early postoperative recovery in the patients undergoing breast cancer surgery.
