Abstract：【Objective】 To explore the sedative value of ultrasound-guided thoracic nerve block Ⅱ (Pecs-Ⅱ) in radical mastectomy of breast cancer . 【Methods】 A total of 84 patients with radical mastectomy due to breast cancer who were treated in our hospital were selected as subjects. All patients were randomly divided into two groups. Among them, 42 patients in the control group received thoracic paravertebral nerve block (TPVB) and 42 patients in the observation group underwent ultrasound-guided thoracic nerve block Ⅱ(Pecs-Ⅱ).The operation time, sufentanil dosage within 24 hours, 24-hour VAS score, heart rate, mean arterial pressure and the incidence of adverse reactions were compared between the two groups. 【Results】 The average operation time of the observation group was 122.14±12.03 min, which was not significantly different from the control group's 135.27±13.26 min (P>0.05). The dosage of sufentanil for PCIA , the VAS score , heart rate and average arterial pressure 24 hours after surgery in the observation group were better than those in the control group. The difference was statistically significant (P<0.05). The incidence of adverse reactions such as nausea, vomiting, excessive analgesia, and respiratory depression in the observation group was lower than that in the control group. The difference between the two groups was statistically significant (P<0.05). 【Conclusion】 Ultrasound-guided Pecs-Ⅱ can effectively improve the analgesic value of women undergoing radical surgery for breast cancer, reduce the dosage of sufentanil, relieve pain, enhance analgesic effect, ensure heart rate and blood pressure well maintained at normal level, and reduce the incidence of adverse reactions. It is worth promoting in clinic.
