Abstract:
Objective To investigate the anesthetic and analgesic effect of thoracic paravertebral block and epidural block combined with general anesthesia for single lung ventilation operation. Methods Totally 75 lung cancer patients undergoing chest open ventilation from Jan. 2016 to Aug. 2017 in our hospital were chosen, and divided into group A (38 cases) and group B (37 cases). The patients in group A were given epidural block combined with general anesthesia, and the patients in group B were given thoracic paravertebral block combined with general anesthesia. The anesthetic effect, puncture complications, thoracic complications one week after operation and pulmonary complications one week after operation were compared between the two groups. Results The pulmonary complications after operation for 1 week, anesthesiaonset time, average blocksaverage number of group A were obvious higher than those of group B (P < 0 . 05 ). The fentanyl and propofol dosage during general anesthesia of two groups had no signi?cant difference (P>0.05). The VAS score of group B after surgery for 6, 12, 24 and 48 h at rest and after surgery for 6 h at cough state of two groups had no signi?cant difference (P > 0 . 05). The VAS scores of group B after surgery for 12, 24 and 48 h were lower than those of group A (P<0.05). At T0–T5, the PaO2 and PvO2 of two groups had no signi?cant difference (P>0.05), at T6, the PaO2 and PvO2 of group A were higher than those of group B (P < 0. 05), at T7, the PaO2 of group A was higher than that of group B (P <0.05). Conclusion The anesthetic effect of thoracic paravertebral block and epidural block combined with general anesthesia is comparable. The postoperative exercise analgesia effect and postoperative oxygenation are better than epidural block, and the postoperative pulmonary complicationsare less.
