Abstract:Objective To explore the influence of ultrasound-guided intercostal nerve block on patients with postoperative breast cancer. Methods From October 2016 to September 2019, 50 cases of breast cancer surgery patients in our hospital were selected as the subjects. According to the random number table method, the patients were divided into the observation group and the control group, 25 cases in each group. The patients in both groups underwent radical mastectomy under general anesthesia. The observation group used ultrasound-guided intercostal nerve block to achieve postoperative analgesia, while the control group used patient-controlled intravenous analgesia (PCIA) to achieve postoperative analgesia. After the operation, the time of tracheal extubation, the time of spontaneous respiration and the time of complete awake of the two groups were recorded, and the scores of analgesia and sedation at 2, 4, 8, 12, 24 h after surgery were compared between the two groups. Results The time of tracheal extubation, the time of spontaneous respiration and the time of complete awake in the observation group were shorter than those in the control group, the differences were statistically significant (P<0.05). The visual analogue scale (VAS) scores of the observation group 2 and 4 h after surgery were lower than those of the control group, and the differences were statistically significant (P<0.05). VAS scores at 8, 12 and 24 h after surgery showed no significant difference between the two groups (P>0.05).The sedation scores of the observation group at different postoperative periods (2, 4, 8, 12 and 24 h after surgery) were all lower than those of the control group, and the differences were statistically significant (P<0.05). Conclusion Ultrasound-guided intercostal nerve block can shorten the time of tracheal extubation, the time of spontaneous respiration and the time of complete awake, and play a better role in sedation and analgesia.
