VAS scores in four groups before and after treatment. Violin-whiskers plots demonstrated the VAS scores on Day 1, 7 and 15. Median values was showed by solid line and the interquartile range was presented by dotted line. The VAS scores at each post-treatment time point in all four groups were lower than the preoperative scores (p < 0.01). The VAS on Day 15 was significantly lower than the initial pre-treatment VAS score (p < 0.0001). D drug therapy, DS drug combined stellate ganglion block therapy, DT drug combined trioxygen autologous blood retransfusion therapy, DST drug combined stellate ganglion block and trioxygen autologous blood retransfusion therapy.
