ABSTRACT
OBJECTIVE:To investigate the effects of preemptive analgesia of parecoxib-sodium for radical mastectomy of breast cancer. METHODS:A total of 60 female patients underwent selective radical mastectomy of breast cancer under general anes-thesia were randomly divided into observation group(40 cases)and control group(20 cases). 15 min before anesthesia induction, observation group was given intravenous injection of Parecoxib-sodium for injection 40 mg. Control group was given intravenous in-jection of 0.9% Sodium chloride injection 5 mL. The pain visual analogue scale(VAS),the frequency of patient controlled intrave-nous analgesia(PCA)and ADR were observed between 2 groups at different time points after surgery. RESULTS:VAS scores of observation group were significantly lower than those of control group 2,4,6,8 h after operation,and the frequency of PCA 0-4, 4-12,12-24,24-36 h after operation was significantly lower than control group,with statistical significance(P0.05). CONCLUSIONS:The preemptive analgesia of parecoxib-sodium can effectively reduce pain degree of patients with breast cancer after radical mastectomy,the frequency of PCA, and do not increase the occurrence of ADR.
