Objective To investigate the application of laryngeal mask combined with thoracic paravertebral block in thoracic sur-gery.Methods Sixty-two patients who received single-port thoracoscopic treatment in our hospital were selected and divided into two groups by random number table method,and in each group there were thirty-one patients,namely DL group(double-lumen bronchi-al cannula)and LM group(laryngeal mask combined with thoracic paravertebral block).The hemodynamic fluctuations in terms of entry to operating room(T0),induction of anesthesia(T1),intubation(T2),skin resection(T3),lung specimen resection(T4),and after extubation(T5),extubation(laryngeal mask)time,length of stay in PACU,the satisfaction of operative field,intraoperative cough,postoperative sore throat,postoperative pulmonary infection and postoperative hospital stay were compared be-tween the two groups.Results The mean arterial pressure of the two groups had no significant difference at T0(P>0.05),but the mean arterial pressure and heart rate of the DL group were significantly higher than those of the LM group at T2,T3 and T5(P<0.05);the mean arterial pressure of DL group at T0 was significantly higher than that at T1 and T4,and significantly lower than that at T2(P<0.05);the heart rate of DL group at T0 moment was significantly higher than that at T1 moment(P<0.05);the mean ar-terial pressure at T1 was significantly lower than that at T2,T3 and T5(P<0.05);the heart rate at T1 was significantly lower than that at T2 and T5(P<0.05);the mean arterial pressure and heart rate of LM group were significantly higher at T0 moments than at T1-T5 moments(P<0.05);the mean arterial pressure at T1 was significantly higher than that at T2-T5(P<0.05);the heart rate at T1 was significantly higher than that at T3(P<0.05);pulse oxygen saturation in DL group at T3 was significantly lower than that in LM group(P<0.05);the duration of laryngeal mask extraction,PACU residence time and postoperative hospital stay in LM group were significantly shorter than those in DL group(P<0.05);there were no significant differences in surgical field satisfaction,intrao-perative cough and postoperative pulmonary infection between the two groups(P>0.05);the incidence of postoperative sore throat in DL group was significantly higher than that in LM group(P<0.05).Conclusion Laryngeal mask combined with thoracic paraverte-bral nerve block is more stable in hemodynamics and faster in postoperative recovery than the classical double-lumen bronchial intuba-tion and general anesthesia in thoracic surgery,which is more consistent with the concept of ERAS.
