Abstract:Objective To investigate clinical efficacy of Diclofenac sodium and Lidocaine combined with analgesics in the treatment of pain. Methods In our hospital 148 cases undergoing anorectal surgery were divided into observation group and control group. The observation group was treated with Diclofenac sodium and Lidocaine combined with analgesics, the control group only used analgesics. The postoperative analgesia was observed and the occurrences of complications were analyzed in the two groups. Results The scores of VAS were different at different time points (F = 11.983,P = 0.000). The VAS scores were different between the observation group and the control group (F = 25.376, P= 0.000), the observation group was different from the control group in the VAS score change trend ( F= 10.307,P = 0.000). There were significant differences in the SS scores at different time points (F = 7.016,P = 0.001). The SS scores of the observation group and the control group were significantly different ( F= 14.375, P= 0.000), the change trend of the SS scores was different between the observation group and the control group (F = 6.309, P= 0.003). The incidences of complications in the observation group were significantly higher than those in the control group. Conclusions Combination of Diclofenac sodium and Lidocaine with long -acting analgesics can significantly reduce postoperative anorectal pain and the rate of complications, is worthy of further promotion in clinical practice.
