摘要: 为探讨白细胞相关体液因素在先天性心脏病(简称先心病)合并重度肺动脉高压围术期肺损伤中的作用机制,对31例先心病室间隔缺损(非肺动脉高压16例,重度肺动脉高压15例)行直视修补术患者的围术期肺动脉压、全肺阻力、血栓素B2(TXB2)、6-酮-前列腺素F1α(6-keto-PGF1α)、丙二醛(MDA)、白介素-8(IL-8)以及动脉血白细胞计数的变化进行了分组研究。结果显示,围术期TXB2、6-keto-PGF1α与TXB2的比值(P/T)、MDA、IL-8、动脉血白细胞以及中性粒细胞计数的变化与围术期肺动脉压、全肺阻力的改变密切相关。提示在先心病合并重度肺动脉高压患者的围术期,白细胞引起的体液因素改变可以造成肺动脉高压患者的肺损伤,并影响其血流动力学。

Abstract: To investigate the mechanism of the humoral factor-leukocyte on lung injury in congenital heart disease(CHD)with severe pulmonary hypertension during perioperation, 31 consecutive cases of CHD with ventricular septal defect(No pulmonary hypertension 16 case, severe pulmonary hypertension 15 case)were studied during perioperation. Mean pulmonary arterial pressure, pulmonary vascular resistance, TXB2, 6-keto-PGF1α, MDA, IL-8, leukocyte and neutrophilic granulocyte number were measured. TXB2,the rate between 6-keto-PGF1αand TXB2(P/T), MDA,IL-8, leukocyte and neutrophilic granulocyte number were closely related to pulmonary pressure,pulmonary vascular resistance and respiration index(RI)in the case of CHD with severe pulmonary hypertension during perioperation. The humoral factor-leukocyte of the cases of CHD with pulmonary hypertension changed significantly during perioperation, which led easily to pulmonary damage. Lung injury during perioperation may affect hemodynamics.
