The Value of Combined Application of Oxycodone Hydrochloride Injection and Dexmedetomidine in Anesthesia for LC for Patients with Gallbladder Lesions

OBJECTIVE: To analyze the effect of combined application of oxycodone hydrochloride injection and dexmedetomidine in anesthesia for laparoscopic cholecystectomy (LC) for patients with gallbladder lesions. METHOD: 93 patients with gallbladder lesions in our hospital were divided into 2 groups by the random number table method. 46 patients in the control group applied oxycodone hydrochloride injection in anesthesia, and 47 patients in the observation group applied oxycodone hydrochloride injection combined with dexmedetomidine in anesthesia. RESULT: The T1 and T2 MAP levels in the observation group were lower than those in the control group (P < 0.05), and the difference between T3 and the control group was not significantly significant (P > 0.05). The T1 to T3 HR level in the observation group were lower than those in the control group (P < 0.05). The rate of excessive sedation (10.64%) and sedation inefficiency (12.77%) in the observation group was lower than that in the control group (28.26% and 30.43%), and the rate of satisfactory sedation (76.60%) was higher than that in the control group (41.30%) (P < 0.05). The postoperative awakening, tracheal tube removal, and first anal venting time were shorter in the observation group than in the control group (P < 0.05). The WHO scores of incisional pain at 6, 12, 24, and 48 hours after the operation were lower in the observation group than in the control group (P < 0.05). The T2 SOD level in the observation group was higher than that in the control group, and the ROS and MDA levels were lower than those in the control group (P < 0.05). The incidence of side effects of anesthetic in the observation group was 17.02%, which was not statistically different from the control group of 13.04% (P > 0.05). CONCLUSION: The combined application of oxycodone hydrochloride injection and dexmedetomidine in anesthesia for LC for patients with gallbladder lesions can achieve better sedation and analgesia effect, accelerate postoperative awakening and recovery, and control oxidative stress and fluctuations in signs, without increasing anesthesia-related side effects.
