Abstract: Objective: To observe the clinical effect of full arch implantation under conscious sedation and analgesia combined with local anesthesia. Methods: Twenty-our patients who needed full arch implantation were randomly divided into the experimental group and control group, with 12 patients in each group. The experimental group used conscious sedation analgesia and local anesthesia, and the control group adopted pure local anesthesia. The mean arterial pressure (MAP), heart rate (HR), and digital oxygen saturation (SpO2) of two groups were recorded before anesthesia (T0), local anesthesia (T1), flap (T2), drilling (T3), and suturing (T4). The sedation scores (RSS) at T1-T4 were recorded, the intraoperative pain scores were performed before leaving the hospital, and the postoperative pain scores were performed 3 days after the operation. Results: MAP and HR at each time point of T1-T4 in the experimental group were significantly lower than those in the control group (P<0.05). The changes of MAP and HR at any time point in the control group showed an increasing trend, while the changes of MAP and HR at any time point in the experimental group showed a decreasing trend. There was no significant difference in SpO2 between two groups at each time point (P>0.05). The RSS scores of the experimental group were significantly better than those of the control group at each time point of T1-T4 (P<0.05), and the pain scores of the experimental group were significantly lower than those of the control group during operation and on the 1st, 2nd, and 3rd day after operation (P<0.05). There was no significant difference in the incidence of adverse reactions between two groups (P>0.05).Conclusion: Conscious sedation and analgesia anesthesia combined with local anesthesia is safe and effective, and can reduce intraoperative and postoperative pain, with less adverse reactions. It is worthy of application in surgery with complex and long operation time, especially in full arch implantation.
