Application of paravertebral nerve block combined with phrenic nerve block in thoracotomy lobectomy
Objective To investigate the application of paravertebral nerve block combined with phrenic nerve block in thoracotomy lobectomy.Methods A total of 105 patients who had elective thoracotomy performed in the People's Hospital of Qiannan Buyi and Miao Autonomous Prefecture from January 2021 to April 2023 were selected as subjects and divided into control group(group C,n=35),paravertebral nerve block group(group N,n=35)and observation group(group O,n=35)by random number table method.Group C was directly induced by general anesthesia.Group N received general anesthesia induction after thoracic paravertebral nerve block.Group O was induced by general anesthesia after thoracic paravertebral nerve block.The intraoperative dosage of Propofol and Remifentanil,postoperative incision pain visual analogue scale(VAS)score,ipsilateral shoulder pain VAS score,the use of patient-controlled analgesia(PCA)within 24 h after surgery were compared among the three groups.Results The dosage of Propofol and Remifentanil in group O were lower than those in group C and N,and the differences were statistically significant(P＜0.05).The VAS score of postoperative incision pain in group O was lower than that in group C,and the difference was statistically significant(P＜0.05).The VAS score of ipsilat-eral shoulder pain in group O was lower than that in group C and group N,and the difference was statistically significant(P＜0.05).The frequency of PCA use in group O within 24 hours after operation was lower than that in group C and group N,and the difference was statistically significant(P＜0.05).Conclusion The application of paravertebral nerve block com-bined with phrenic nerve block in thoracotomy lobectomy can reduce the amount of general anesthetics during the operation,reduce the postoperative incision pain and ipsilateral shoulder pain of patients,reduce the number of postoperative PCA use.It is worthy to be popularized in clinical anesthesia to ben-efit the majority of patients.
