心血管机能紊乱在小儿支气管肺炎中占有重要地位,其受累程度常能决定肺炎的经过及结局。虽然早在19世纪各学者即注意到肺炎时的循环紊乱,以后进行了多种临床、病理及实验室研究,但迄今为至对肺炎时心血管机能紊乱的发病机制、性质及程度方面尚无统一见解。常见的原因有:(1)缺氧(包括低氧血症及呼吸酶系统的障碍);(2)肺实变或肺气肿等所致肺循环压力增加;(3)心肌炎症;(4)呼吸性酸中
Cardiovascular disorders play an important role in bronchial pneumonia in children, and the degree of involvement often determines the course and outcome of pneumonia. Although as early as the 19th century, when scholars noticed the circulatory disturbance in pneumonia and subsequently conducted a variety of clinical, pathological and laboratory studies, up to now there is still no study on the pathogenesis, nature and extent of cardiovascular dysfunction in pneumonia Uniform opinion. Common causes are: (1) hypoxia (including hypoxemia and respiratory enzyme system disorders); (2) increased pulmonary pressure due to lung consolidation or emphysema; (3) myocardial inflammation; (4) Respiratory acid
