RESUMEN
OBJECTIVE: To investigate the effects of combined acupuncture anesthesia and ropivacaine on postoperative analgesia and neuro-related factors in patients undergoing chest surgery. METHODS: The analgesic drug dosage, postoperative PCIA pressing times, VAS scores at rest and during activity at 6 h (T1), 12 h (T2), 18 h (T3), and 24 h (T4) postoperatively. RESULTS: The analgesic drug dosage and postoperative PCIA pressing times were lower in the observation group than in the control group (p < 0.05). The VAS scores at T1-T4 postoperatively were lower in the observation group than in the control group (p < 0.05). The SAS scores at T1-T4 postoperatively were lower in the observation group than in the control group (p < 0.05). The levels of IL-6 and IL-10 on postoperative day 1 were higher than those on preoperative day 1 in both groups, with a smaller change in the observation group (p < 0.05). The levels of S100ß protein on postoperative day 1 were higher than those on preoperative day 1 in both groups, while the BDNF levels were lower, with a smaller change in the observation group (p < 0.05). There was no significant difference in the incidence of adverse reactions between the control group (11.36%) and the observation group (15.56%) (p > 0.05). CONCLUSION: Combined acupuncture anesthesia and ropivacaine can effectively improve postoperative analgesia and agitation in patients undergoing chest surgery, reduce the dosage of analgesic drugs, regulate the levels of inflammatory factors and neurotrophic factors in patients, and do not increase the risk of adverse reactions related to patients.
