    Abstract:
    PURPOSE: To observe the effect of ketorolac tromethamine combined with remifentanil in sedation and analgesia during general anesthesia emergence and reducing general anesthesia complications. DESIGN: This is an experimental design. METHODS: A total of 90 patients who underwent partial or total thyroidectomy in our hospital were selected and randomly divided into three groups with 30 cases in each group. Routine general anesthesia combined with endotracheal intubation was given for general anesthesia, and different treatments were administered when the skin was sutured. Group K: intravenous injection of ketorolac tromethamine 0.9 mg/kg, intravenous injection of normal saline 10 mL/h by micropump until awakening and extubation; R group: intravenous injection of normal saline 2 mL, micropump intravenous injection of remifentanil 0.1 mcg/kg/min until awakening and extubation; KR group: intravenous injection of ketorolac tromethamine 0.5 mg/kg, micropump intravenous injection remifentanil 0.05 mcg/kg/min until awakening and extubation. After the operation, all patients entered the postanesthesia care unit (PACU) for recovery, extubation, scoring. The incidence and condition of various complications were counted. FINDINGS: There was no significant difference in the general information or operation duration of the patients (P > .05). The types of general anesthesia induction drugs in each group were the same, and there was no significant difference in drug measurement (P > .05). The visual analogue scales of KR group were: 2.2 ± 0.6(T0) and 2.4 ± 0.9(T1), the Self-Rating Anxiety Scale scores of the KR groups were: 4.1 ± 0.6(T0), 3.7 ± 0.4(T1). Compared with the KR group, the visual analogue scale and Self-Rating Anxiety Scale scores of the K and R groups at T0 and T1 were increased (P < .05); the visual analogue scale and Self-Rating Anxiety Scale scores of the K and R groups at T0 and T1 were not significantly different (P > .05); at T2, there was no significant difference in visual analogue scale and Self-Rating Anxiety Scale scores among the three groups (P > .05). There was no significant difference in extubation time or PACU transfer time among the three groups (P > .05). The incidence of adverse reactions in KR group were: 3.3% (nausea), 3.3% (vomit), 0 (coughing and drowsiness). Compared with the KR group, the incidence of adverse reactions was higher in the K and R groups. CONCLUSIONS: Ketorolac tromethamine combined with remifentanil can effectively relieve pain and sedation during general anesthesia recovery and reduce the incidence of complications related to general anesthesia recovery. At the same time, the application of ketorolac tromethamine can reduce the dosage of remifentanil and inhibit the occurrence of adverse reactions when used alone.
