To investigate the anesthesia effect and postoperative analgesia of dexmedetomidine combined with bupivacaine in patients undergoing Lichtenstein surgery.

74 patients with inguinal hernia admitted to Suixi County Hospital, Anhui from May 2020 to June 2022 were selected as study subjects, and divided into control group (37 patients) and study group (37 patients) by random number table method. The control group received glucose, sufentanil and bupivacaine, the study group received dexmedetomidine and bupivacaine. The clinical effects, surgery-related indicators, anesthesia-related indicators, visual analog scale (VAS) score, Bromage score, Ramsay score, and adverse reactions were compared between the two groups.

(1) The total excellent and good rate of anesthesia effect in the study group was 94.59%, which was significantly higher than 78.39% in the control group (P<0.05). (2) The intraoperative bleeding in the study group was significantly less than that in the control group; the recovery time of gastrointestinal function, operation time and hospital stay were significantly shorter than those in the control group (P<0.05). (3) The onset time of anesthesia, duration of motor nerve block, and duration of sensory block in the study group were significantly shorter than those in the control group; the duration of analgesia in the study group was significantly longer than that in the control group (P<0.05). (4) The postoperative VAS and Bromage scores of the study group were significantly lower than those of the control group, and the Ramsay score was significantly higher than that of the control group (P<0.05). (5) The total incidence of adverse reactions in the study group was 8.11%, which was significantly lower than 27.02% in the control group (P<0.05).
