Abstract:Objective To analyze the effects of stellate ganglion block (SGB) on inflammatory factors and lung function in severe acute pancreatitis (SAP) complicated with acute lung injury (ALI). Methods A total of 34 cases of severe acute pancreatitis patients in intensive care unit (ICU) department of the first affiliated hospital of Hebei northern university from June 2016 to December 2018 were recruited, which randomly divided into 19 cases with routine treatment group (control group) accepted critical care associated treatment and 15 cases with ultrasound-guided stellate ganglion block combined with routine treatment group (SGB group). Enzyme linked immunosorbent assay was used to detect the changes of TNF-α, IL-1β, IL-6, IL-10, and blood cell analysis was applied to examine the level of C reactive protein (CRP) and white blood cell (WBC). The differences of lung water index and oxygenation index between pre- and post-treatment, the length of ICU duration, the time of tracheal extubation, and the change of inflammatory factors in T0, T1, T2, T3 admitted into ICU between SGB group and control group were observed. Results In pre-treatment, there was no difference in the level of lung water index and oxygenation index between two groups (P?>?0.05). 2 weeks after treatment, compared with control group, the level of lung water index was decreased and the level of oxygenation index was increased significantly in SGB group (P?0.05), meanwhile, the length of ICU duration and the time of tracheal extubation were less in SGB group (P?0.05). Contrasted with control group, the level of IL-6, TNF-α, IL-1β, IL-10, WBC and CRP in T0, T1, T2, T3 were significantly different (P?< 0.05). Meanwhile, compared to control group, the level of IL-6, TNF-α, IL-1β, CRP and IL-10 were different in the time of T2 (P?0.05), and the time related change trends of TNF-α, IL-1β, IL-10 and WBC, CRP were significantly distinctive (P?0.05). Conclusion SGB may alleviate lung injury by regulating inflammatory factors in SAP-ALI.
