Abstract

To observe the effects of general anesthesia combined with different anterior muscle plane block methods on pain relief and cognitive function in patients undergoing thoracoscopic lobectomy. 120 patients who were scheduled to undergo thoracoscopic lobectomy at a thoracic hospital from October 2022 to October 2023 were chosen and separated into a control group, namely the patient controlled intravenous anesthesia group; serratus muscle plane block group, namely single anterior serratus muscle plane block group and continuous insertion of serratius muscle plane block group. The time for first postoperative activity was shortened, and the total length of hospitalization was reduced (p<0.05). Relative to the patient controlled intravenous anesthesia group, the postoperative cognitive function of the single anterior serratus muscle plane block and continuous insertion of serratius muscle plane block groups was markedly improved, and the incidence of adverse events was markedly reduced (p<0.05). After thoracoscopic lobectomy, general anesthesia combined with anterior serratus muscle plane block is an important part of multimodal analgesia, which can provide patients with a good postoperative analgesia. The analgesic effect of single anterior serratus muscle plane block combined with patient-controlled intravenous analgesia mode is the best, and it can also reduce the incidence of adverse reactions caused by the total use of opioid drugs; the patient's comfort level is very high, and it can also enhance the early postoperative recovery and cognitive function, promoting the acceleration of rehabilitation process during the perioperative period.
