Abstract
OBJECTIVE: To evaluate the efficacy of Xuebijing Injection (, XBJ) on the lung injury induced by cardiopulmonary bypass (CPB). METHODS:Fifty patients undergoing CPB were randomized to either the saline group or XBJ group according to a random number table (25 cases in each group). The patients in the saline group received saline and patients in XBJ group received XBJ at 12 h prior to the operation, at the beginning of the operation, and at 12 h after the second injection. The PaO2/FiO2 at extubation 3 days post-operation, duration of ventilation in the intensive care unit (ICU), and lengths of stay in the ICU and hospital were recorded. The levels of inflammatory mediators including interleukin (IL)-1β, IL-8, IL-10, and C-reactive protein (CRP) in bronchoalveolar lavage fluid (BALF) and plasma were measured. The neutrophil count and elastaseneutrophil elastase in BALF were also measured. In addition, adverse events were monitored. RESULTS: The PaO2/FiO2 in the XBJ group was higher than that in the saline group from 12 to 72 h post-operation (all P<0.05). The blood levels of IL-1β, IL-8, and CRP in the XBJ group from 12 to 72 h were all significantly lower than those in the saline group (all P<0.05). In contrast, the level of the anti-inflammatory cytokine IL-10 was significantly higher in the XBJ group than in the saline group (P<0.05). In addition, 4 patients presented with atelectasis in the saline group and none in the XBJ group. Ten patients experienced mild acute respiratory distress syndrome (ARDS) during hospitalization, and 5 patients with mild ARDS were in the XBJ group (P<0.05). CONCLUSION:XBJ shows protective potential against lung injury in patients who undergo CPB surgery, possibly through the downregulation of inflammatory mediators, reduction in neutrophil infiltration, and upregulation of IL-10 (Trial registry: ChiCTR-TRC-14004628).
