Effect of ultrasound-guided serratus anterior plane block on the pain, inflammation and oxidation after radical mastectomy

摘要

cqvip:Objective:To study the effect of ultrasound-guided serratus anterior plane block on the pain, inflammation and oxidation after radical mastectomy.Methods: Patients who underwent radical mastectomy in Qinghai Provincial People's Hospital between March 2015 and December 2017 were selected as the research subjects and randomly divided into the experimental group who accepted ultrasound-guided serratus anterior plane block combined with general anesthesia and the control group who accepted general anesthesia. The pain mediators, inflammatory molecules and oxidative stress molecules were measured before surgery and 3 d after surgery.Results: Compared with those of same group before surgery, serum NPY, SP, PGE2, CGRP, IL-1β, IL-18, TNF-α, MDA and 8-iso-PGF2 levels as well as peripheral blood NF-κB, NLRP3, NOX4 and MPO expression intensity of both groups of patients were increasing whereas serum SOD levels were decreasing after surgery, and serum NPY, SP, PGE2, CGRP, IL-1β, IL-18, TNF-α, MDA and 8-iso-PGF2 levels as well as peripheral blood NF-κB, NLRP3, NOX4 and MPO expression intensity of experimental group after surgery were lower than those of control group whereas serum SOD level was higher than that of control group.Conclusion:Ultrasound-guided serratus anterior plane block has significant inhibitory effect on the pain, inflammation and oxidation degree after radical mastectomy.
