OBJECTIVE: To investigate and compared the efficacy and safety of epidural analgesia with different concentrations of bupivacaine plus fentanyl on pain in patients undergoing thoracic surgery. METHODS:120 cases undergoing elective thoracic surgery were randomly divided into A, B, C and D four groups each with 30 cases, and they were treated with 0.25% (A group), 0.375% (B group), 0.50% (C group) and 0.75% (D group) bupivacaine plus fentanyl 0.4 mg. The pain conditions postoperative 4 h, 8 h, 12 h, 24 h and 48 h were evaluated by visual analogue scale (VAS). The PCA pressing numbers and incidence of adverse reactions were compared between the four groups. RESULTS: By postoperative 4 h, the VAS in D group were obviously lower than those in the other three groups (P all <0.05), and the other three groups showed no significances (P>0.05). However, the four groups showed no significant differences in VAS by postoperative 8 h, 12 h, 24 h and 48 h (P all >0.05). The incidences of respiratory depression in C and D groups were markedly higher than those in A and B groups (P all <0.05). CONCLUSIONS: 0.25%~0.375% bupivacaine plus fentanyl 0.4 mg using in epidural analgesia in patients undergoing thoracic surgery can lead to safe and effective analgesic effect.
