- Abstract: Objective To observe the effects of ultrasound-guided C7 stellate ganglion block (SGB) on hemodynamics during periextubation of general anesthesia. Methods Sixty patients undergoing elective surgery of chest and abdomen (ASA grade Ⅰ/Ⅱ) were selected and then divided into groups A, B and C according to a random number table, with 20 patients per group. Preoperative intubation was rapidly induced by general anesthesia, and intraoperative mechanical ventilation was adopted during surgery. Before the patients were taken to postanesthesia care unit after the stop of anesthesia, the patients in groups A and B were separately treated with left and right ultrasound-guided C7 SGB at the end of the surgery, while no postsurgery operation was carried out in group C. When the patients met the extubation indications, endotracheal intubation was removed with sputum aspiration. The systolic blood pressure, diastolic blood pressure and heart rate were recorded before leaving the operating room (the foundation value, T0), when the tracheal tube was removed (T1) and 5 min after extubation (T2). Meanwhile, the number of cases of appearing Horners syndrome was recorded, and the occurrence of related complications such as hoarseness and neurovascular injury were observed in groups A and B after SGB. Results Compared with those in groups A and B, the systolic blood pressure and diastolic blood pressure in group C were significantly increased and heart rate was significantly accelerated at T1 and T2 as compared with T0 (P<0.05). Horners syndrome occurred in groups A and B after SGB, but no related complication was found. Conclusion Ultrasound-guided C7 SGB can effectively reduce cardiovascular response during extubation in patients undergoing elective surgery of chest and abdomen. Moreover, because of its high success rate and fewer complications, ultrasound-guided C7 SGB is considered safe and effective.
