Anesthetic Effect and Safety Analysis of Different Concentrations of Ropivacaine Combined with or Without Dexmedetomidine in Upper Limb Surgery
Objective:To study the anesthetic effect and safety of different concentrations of ropivacaine combined with or without dexmedetomidine in upper limb surgery. Methods:A total of 80 patients with upper limb surgery admitted to our hospital from January 2021 to December 2022 were divided into four groups according to different anesthesia. Group A (simple low concentration ropivacaine),group B (low concentration ropivacaine combined with dexmedetomidine),group C (simple high concentration ropivacaine combined with dexmedetomidine),with 20 patients in each group. The anesthetic effect,intraoperative hemodynamics and postoperative pain score were compared among different groups. Results:The onset time of anesthesia in group D was shorter than that in other groups,the time of sensory and motor block was longer than that in other groups,and the complete block rate of musculocutaneous nerve,radial nerve and ulnar nerve was higher than that in other groups (P<0.05). The mean arterial pressure in group D was higher than that in other groups at the end of operation (P<0.05). The pain scores of awakening,resting and coughing at 1 h after operation in group D were lower than those in other groups (P<0.05). Conclusion:High concentration ropivacaine combined with dexmedetomidine can improve the anesthesia effect in upper limb surgery,have little effect on intraoperative hemodynamics,reduce pain perception,and have good anesthesia safety.
