Abstract：Objective:To investigate the effect of ultrasound-guided serratus anterior plane block(SAPB)on postoperative oxygenation and complications in patients under thoracoscopic lobectomy.Methods:68 patients who underwent thoracoscopic lobectomy in the hospital from 2020 to 2023 were randomly divided into two groups:observation group(group SP)and control group(group P).30 min before general anesthesia induction,all patients in group SP were performed with SAPB of the operative side using 0.4%ropivacaine 120 mg combined with dexamethasone 5 mg,and no special treatment was performed in group P.Oxygenation at different times,perioperative analgesia and the occurrence of postoperative pulmonary complications and adverse reactions between the two groups were compared.Results:Compared with group P,the postoperative oxygenation index(OI)of patients in group SP at t2,t3,t4 and t5 time points were significantly increased,and the difference was statistically significant(t=2.19,2.22,3.01,2.47;P＜0.05).Compared with group P,the first compression time of PCIA in group SP was significantly longer within 48 h after operation.Intraoperative dosage of remifentanil,effective compression times,remedial analgesia rate,tramadol dosage decreased significantly,and the difference was statistically significant(t=46.08,2.81,23.08,5.87;P＜0.05).Compared with group P,the anesthesia recovery time of patients in group SP was significantly shortened,and the incidence of agitation,atelectasis,hypoxemia,PONV and dizziness during the recovery period were significantly reduced,with statistically significant difference(t=13.46;χ2=6.91,4.51,5.04,4.51,5.67;P＜0.05).Conclusion:Ultrasound-guided serratus anterior plane block can improve the pulmonary oxygenation,reduce analgesic,and decrease the incidence of adverse reactions in patients undering thoracoscopic lobectomy.
