Results The pain VAS score at 24 h, 48 h and 72 h at the research group were significantly lower than the control group (P<0.05). The quality of life scores of mental health, physiological function, overall health, and physical pain in research group group at 72 hours after surgery were significantly higher than those in the control group (P<0.05). The incidence of complications, such as urinary retention, anal swelling, nausea and vomiting, was significantly lower than that of the control group, and the difference was significant (P<0.05). The satisfaction of anesthesia at 72h was significantly higher than the control group, statistically significant (P<0.05).
