Objective To compare the effectiveness and safety of two approaches for ultrasound-guided stellate ganglion block. Methods A total of 100 patients with stellate ganglion block in our hospital from October 1, 2023 to October 31, 2024 were randomly divided into a study group (modified lateral cervical approach) and a control group (anterior approach), 50 cases in each group. The one-time puncture success rate, onset time, Horner syndrome occurrence time, and incidence of adverse reactions of puncture were statistically analyzed between the two groups. Results The one-time puncture success rate in the study group was higher than that in the control group (P<0.05), and the onset time was shorter than that in the control group (P<0.05). The occurrence time of Horner syndrome in the study group was mainly concentrated in 5 minutes after needle removal, accounting for 54.00%, while the occurrence time of Horner syndrome in the control group was mainly 2 minutes after needle removal. The difference in the occurrence time of Horner syndrome between the two groups was statistically significant (P<0.05). The incidence of puncture blood return, puncture paresthesia, and recurrent laryngeal nerve block was lower than that in the control group (P<0.05). Conclusion The modified lateral cervical approach for ultrasound-guided stellate ganglion block can reduce the incidence of complications and adverse reactions compared with the anterior approach, which is expected to guide the selection of ultrasound-guided stellate ganglion block approach in our hospital, provide guidance for the clinical implementation of stellate ganglion block, and improve the expected treatment effect and patient satisfaction.
