Methods:Eight patients with major burn, complicated by invasive burn wound infection and sepsis were consecutively admitted to our hospital from September 1997 to October 1998. REEs were monitored by means of Cardiorespiratory Diagnostic System (Medical Graphics Corporation, USA) at patients bedside. Plasma concentration of IL-6、IL-8、TNF-α and LPS were assayed before an...展开更多

The plasma concentration of IL-6, IL-8, TNFα and LPS were assayed before and after surgical intervention, as well as when the patients vital signs became stable. The results showed: ①The patients' conditions abruptly deteriorated when the burn wound sepsis emerged.展开更多
