RESULTS: Compared between 24 h and 48 h among Dezocine group,Sufentanil group and Sufentanil combined with Zuoxin Group ,Sufentanil combined with Zuoxin Group had higher VAS, BCS,vomiting score, and there were statistically significant among three groups (P<0.05). Adverse reactions in addition to stupor,respiratory rate and mean arterial pressure had no significantly different between three groups(P>0.05),the jiont group had better results than those of other two groups in other indicators (P<0.05).
