Abstract:

To observe the safety and effectiveness of ultrasound-guided stellate ganglion block (SGB). Methods Seventy-six patients who required SGB treatment and had no contraindications, were divided into two groups using the random number table method, the ultrasound group (n= 38) and conventional group (n=38). The following indicators were observed: the total operation time, Horner's sign, patients with significant discomfort during the operation, the incidence of pain at the injection site, laryngeal recurrent nerve block, brachial plexus block, adverse reactions, such as local anesthetics poisoning.Results In the ultrasonic group SGB block horner's sign occurrence rate (98.5%) was higher than that in conventional group (81.1%; the incidence of discomfort in the ultrasound group (1.2%) was far lower than that in conventional group (23.5%); in the ultrasonic group, the incidence of pain after multiple block at the injection site (2.7%) was significantly lower than in conventional group (18.3%). The incidence of adverse reactions, such as laryngeal recurrent nerve block (0.6%), brachial plexus block (0.9%), local anesthetics poisoning (0.3%) were lower than those in conventional puncture group (5.6%, 5.6%, 7.7% respectively). The differences between the 2 groups were statistically significant (P<0.05). Conclusion Ultrasound-guided localization of SGB compared to traditional method, the success rate and safety were higher, with more advantages, therefore it is worthy of clinical use.
