Objectives: To analyze the effect of general anesthesia compound thoracic paravertebral blockade on postoperative pain relief for patients in thoracic surgery.
Methods: Patients were divided into two groups according to the anesthesia method they received. In group 1, the control group, patients only got general anesthesia. In group 2, on the basic of general anesthesia, patients were jointly used paravertebral nerve block anesthesia. After operation, the visual analogue scale (VAS) was adopted to grade patients’ pain on 4 h, 8 h, 12 h, 24 h after operation in quiet and cough, and the usage amounts of analgesic of patients in two groups were taken statistic within 24 hours after operation.
Results: In quiet and cough, the postoperative VAS scores of patients in group 2 were significantly lower than those in group 1, the usage amounts of analgesic of patients in group 2 less than those in group 1.
Conclusion: General anesthesia compound thoracic paravertebral blockade has significantly analgesic effect on patients after surgery, which is benefit to relieve pain and signally reduce the usage amounts of analgesic after surgery.
