Abstract Objective: To investigate the effect of phrenic nerve protection during video-assisted thoracoscopic resection of mediastinal tumor and its influence on surgical indexes and postoperative recovery. Methods: A total of sixty-six patients with mediastinal tumors in our hospital from January 2015 to December 2019 were selected for a prospective study, and were divided into experimental group and control group according to the principle of digital randomness, with 33 patients in each group. The control group was treated with standard thoracotomy. The experimental group underwent mediastinal tumor resection by video-assisted thoracoscopy and phrenic nerve protection measures. The intraoperative and postoperative indicators and phrenic nerve fluctuation were compared. Results: Intraoperatively, the time of thoracotomy (12.07±3.27)min, the amount of thoracotomy blood loss (12.89±4.68) min, and the time of thoracotomy (11.46±2.39)min in the experimental group were all lower than those in the control group, and the differences were statistically significant (P<0.05). The difference in total operation time was not significant, and was not statistically significant ( P>0.05). After the operation, the experimental group had less catheter duration (3.25±0.95) d, drainage volume (365.89±102.49) ml, and length of hospital stay (7.79±2.19) d than the control group, and P<0.05 was statistically significant. Intraoperative and postoperative indicators showed a positive correlation, but the degree of strength was different, P<0.05 was statistically significant. The upsilon /V was (186.25±28.54) in the experimental group and (120.22±25.36) in the control group. There was significant difference in data on the upsilon /V, with t=9.935,P<0.05 being of statistical significance. Conclusion: Video-assisted thoracoscopic resection of mediastinal tumor can reduce the time of thoracotomy, chest closing, hospital stay and catheter insertion, reduce the amount of blood loss, maintain the phrenic nerve, and avoid the phrenic nerve injury.
