A pilot study of intraoperative intercostal nerve block during uniportal thoracoscopic wedge resection of the lung
Abstract: BACKGROUND AND AIMS: Uniportal thoracoscopic surgery has been reported to result in alleviating the postoperative pain when compared with traditional video-assisted thoracoscopic surgery (VATS).However, postoperative pain is still the main concerns associated with thoracic surgeries. The objective of this study is to evaluate the postoperative pain of patients undergoing uniportal VATS, especially wedge resection, with the use of intraoperative intercostal nerve block. METHODS: All consecutive patients undergoing the uniportal VATS wedge resection between January 2019 and March 2020 were reviewed retrospectively. Twenty consecutive patients in Group A underwent the uniportal VATS wedge resection without intraoperative intercostal nerve block. The other 20 consecutive patients in Group B underwent the uniportal VATS wedge resection with intraoperative intercostal nerve block. The numeric pain rating scale (NRS) scores were recorded at 1, 12, and 24 h, postoperatively. The number of opioid consumption was also recorded until the time to chest tube removal. RESULTS: There was no difference between groups with regard to sex, age, chest tube duration, length of stay, operative time, laterality time, and diagnosis. There was a significant difference in postoperative NRS scores at 1 h (P = 0.001) and 12 h (P = 0.022) between the groups. The opioid consumption was significantly in Group B lower than those in Group A (P = 0.025). CONCLUSION: The intraoperative intercostal nerve block with bupivacaine provided immediate postoperative pain relief with reducing the postoperative opioid consumption compared in patients who underwent uniportal VATS, especially wedge resection of the lung.
