Abstract
BACKGROUND: Propofol combined with remifentanil is the most common anesthesia method in laparoscopic hysteromyomectomy. However, whether the combination of the two is helpful to patients undergoing hysteromyomectomy still requires unclear. OBJECTIVE: To determine the effect of parecoxib sodium combined with dexmedetomidine on analgesia and postoperative pain of patients undergoing hysteromyomectomy. METHODS: Altogether, 72 patients receiving hysteromyomectomy in our hospital from February 2017 to March 2019 were enrolled. Among them, 35 patients treated with parecoxib sodium were assigned to the control group, while the rest 37 patients treated with parecoxib sodium combined with dexmedetomidine were assigned to the research group. The following items of the two groups were evaluated: visual analog scale (VAS) score, mechanical pain threshold (MPT), Riker sedation-agitation scale (RSAS) score, and expression of serum cortisol and melatonin. RESULTS: At 12 and 24 h after operation, the VAS score of the research group was lower than that of the control group (P < 0.05), and at 6, 12, and 24 h after operation, the MPT of the research group was notably higher than that of the control group (P < 0.05). In addition, at 10 min after extubation, the research group got notably lower RSAS score than the control group (P < 0.05). Before extubation and at 20 min after extubation, the research group showed notably higher melatonin expression and notably lower serum cortisol expression than the control group (both P < 0.05). CONCLUSION: Parecoxib sodium combined with dexmedetomidine can effectively control the postoperative pain of patients undergoing hysteromyomectomy, reduce the incidence of agitation, and effectively control serum cortisol and melatonin in them.
