Comparison of intravenous analgesia with dezocine and sufentanil after radical resection of rectal cancer

Objective: To compare the efficacy of dezocine and sufentanil in patient intravenous analgesia after radical resection of rectal cancer. Methods: Sixty patients arranged for radical resection of rectal cancer were randomly divided into dezocine group( group D) and sufentanil group( group S). After operation two groups were respectively given by intravenous injection( PCA) were decozine 0. 7 mg /kg( group D) and sufentanil 1. 5 μg /kg( group S) which were diluted to 60 mL by Visual Analogue Scale( VAS) and Ramsay scores after operation and adverse effects were recorded and compared. Results: There was no significant difference in the VAS scores( P 0. 05). The Ramsay scores and adverse effects in group D were significantly lower than those in group S( P 0. 05). Conclusion: The postoperative analgesia with dezocine can serve as a safe and effective method of analgesia in patient of radical rectal cancer.
