Ultrasound-Guided Bilateral Superficial Cervical Plexus Block Enhance the Quality of Recovery in Patients following Parathyroidectomy with Secondary Hyperparathyroidism

Abstract

Background:Parathyroidectomy has been proposed as method for reduction of PTH levels. We evaluated the effects of ultrasound-guided BSCPB on the quality of recovery following parathyroidectomy with secondary hyperparathyroidism.Methods:Eighty-two patients undergoing parathyroidectomy with secondary hyperparathyroidism were randomly allocated to BSCPB group (ultrasound-guided BSCPB with 7.5ml of ropivacaine 0.5% on each side) and the CON group(normal saline).The primary outcome of QoR-40 score was recorded.Secondary outcomes including total consumption of propofol and remifentanil,the numbers of patient requiring rescue analgesia, the time to first require rescue analgesia, the incidence of PONV, and the VAS scores were recorded.Results:The score in the pain and emotional state dimensions of QoR-40,and total QoR-40 score were higher in the BSCPB group than the CON group on POD1(P=0.000).Compared with the CON group,the total consumption of propofol and remifentanil was significantly decreased in the BSCPB group (P=0.000).Compared with the CON group, the time to first require rescue analgesia was longer(P=0.018),and numbers of patient requiring rescue analgesia were decreased in the BSCPB group ( P=0.000).The incidence of PONV was significantly lower in the BSCPB group than the CON group (P<0.05).The VAS scores in the BSCPB group were lower than the CON group in any time point after surgery (P=0.000). Conclusion: Ultrasound-guided BSCPB with ropivacaine 0.5% can enhance the quality of recovery, postoperative analgesia, and reduce the incidence of PONV following parathyroidectomy with secondary hyperparathyroidism.Trial registration: ChiCTR1900027185.
