Abstract:Objective To study the applicability of ultrasound-guided thoracic paravertebral nerve block in external ear reconstruction with autogenous costal cartilage transplantation.Methods Between May 2018 and November 2019, 60 children in the second stage of external ear reconstruction with costal cartilage transplantation were randomly divided into the general anesthesia group (group A) and paravertebral nerve block group (group B). The difference in anesthetic effect, postoperative analgesia, intraoperative general anesthesia dosage and postoperative adverse reactions was observed between the two anesthetic methods for external ear reconstruction.Results 1% propofol (725.69±145.50)mg and remifentanil (2129.90±536.72)μg were used in group B, while propofol (914.58±242.41)mg and remifentanil (3266.79±770.64)μg were used group A. The usage of the two drugs was significantly less in group B than in group A (P<0.05). The heart rate and blood pressure responses of group B were significantly lower than those of group A. The recovery time (T0)was (15.00±1.46)min in group A and(11.53±1.43)min in group B, which was significantly shorter than in group A (P<0.05). The incidence of such adverse reactions as cardiovascular events, nausea, vomiting and constipation was significantly lower in group B than in group A (P<0.05).Conclusions Ultrasound-guided thoracic paraspinal nerve block combined with general anesthesia has been applied to the reconstruction of external ears with autogenous costal cartilage transplantation. Compared with general anesthesia alone, the anesthetic effect of this approach is significant during operation. The hemodynamics is more stable. The dosage of drugs for general anesthesia is significantly reduced. The advantages of postoperative analgesia are obvious, recovery is faster, and there are fewer adverse reactions.
