Analysis of the Necessity of Stellate Ganglion Block after Anesthesia to Reduce the Risk of Cardiovascular Accidents in Coronary Heart Disease

Abstract

Objective: To adjust the sympathetic nervous system through preoperative ultrasound-guided stellate ganglion block and to explore and analyze the situation and necessity of postanesthesia stellate ganglion block to reduce the risk of cardiovascular accidents in coronary heart disease. Methods: 80 patients with cardiovascular risk factors in Songshan Hospital of Chifeng were selected, and the time span would cover from October 2022 to June 2024, with 80 cases of elective surgery and combined coronary heart disease. They will be randomly divided into blocked groups and conventional groups, 40 cases each. Conventional block was performed after anesthesia in patients in the conventional group, and planetary ganglion block was performed after anesthesia in patients in the blocked group. The cardiovascular responses of patients in the two groups were observed, and the number of intraoperative cardiovascular active drugs and the occurrence of cardiovascular adverse events were recorded in patients in the two groups. Results: Analysis of the mean arterial pressure (MAP) and heart rate (HR) values of the two groups of patients at the time points before anesthesia (T0), the moment of tracheal intubation (T1), the moment of surgical skin cutting (T2), the end of the operation (T3), and the 6h postoperative period (T4) showed that the MAP and HR of the blocked group were lower than those of the conventional group at the time points of T1 to T4, and the differences in MAP and HR values of the two groups in different time points compared with the T0 time point were statistically significant (P < 0.05) and the differences in cardiovascular response (P < 0.05) were statistically significant (P < 0.05). significance (P < 0.05). The number of intraoperative cardiovascular active drugs used in the blocked group was shorter than that in the conventional group, and the incidence of cardiovascular adverse events was lower than that in the conventional group, with a statistically significant difference (P < 0.05). Conclusion: By implementing preoperative ultrasound-guided stellate ganglion block in patients with cardiovascular risk factors, the frequency and degree of coronary heart disease symptoms will be reduced, thus reducing the risk of patients, which is worth promoting.
