COMPARATIVE ANALYSIS OF THE EFFECTIVENESS OF TRADITIONAL POSTOPERATIVE ANALGESIA AND ESP BLOCK IN RADICAL BILATERAL MASTECTOMY

Introduction: According to the Global Cancer Observatory, breast cancer occupies a leading position in the world. According to the Bureau of National Statistics, in the structure of oncological morbidity, breast cancer ranks first (13.2%); lung cancer (10.0%) ranks second, colorectal cancer (9.3%) ranks third, and stomach cancer (7.4%) ranks fourth. Numerous studies and meta-analyses provide valuable data on the frequency, nature and risk factors of pain syndrome after mastectomy. According to studies, the frequency of occurrence of POPS after mastectomy varies from 20% to 68%, depending on the criteria for assessing the study and the nature of pain. In this regard, we, within the framework of the project "Creation and implementation of innovative methods for treating oncological diseases" conduct a comparative prospective study in patients with radical mastectomy. We present the intermediate results of the data obtained. Aim: to conduct a comparative analysis of the effectiveness of traditional postoperative analgesia and erector spinae plane (ESP) block in radical mastectomy. Materials and methods: the study was conducted at NROC in Astana. The study involved 40 patients after radical bilateral mastectomy Results: Both groups included patients who underwent bilateral radical mastectomy. In both groups, general endotracheal anesthesia was performed using inhalation anesthesia. Thus, the first registration of pain in the control group occurred after 57.7±16.3 minutes, while in the main group the first intense pain according to VAS more than 5 points was registered after 713.8±129.8 minutes ((p<0.05). Conclusion. Thus, the results obtained in our study show the high and reliable effectiveness of the ESP block in the early postoperative period in patients with radical mastectomy. Publications of peerreviewed journals also emphasize the high importance of regional anesthesia in the prevention of postoperative complications during mastectomy. Moreover, these are not single effects, but a complex improving patient outcomes after radical bilateral mastectomy.
