Notes: Data were expressed as mean±SD; group C, control group; group N, nalbuphine group; group M, midazolam group; min, minute; p1, group C versus group N; p2, group C versus group M; p3, group N versus group M; p < 0.05 was significant and p <0.001 was highly significant. F-test (ANOVA), one way analysis of variance. Post hoc test was done to detect exactly which groups had a difference in means.
