败血性休克由革兰氏阳性或阴性菌感染引起,休克的确定是以收缩压低于90m mHg戒原有高血压患者收缩压下降超过50m mHg。约1╱3的菌血症病人可发生败血性休克。临床特征常与其他类型休克不同,在出现低血压之前紧接着先有寒颤,病人可处于温休觅状态而无外周血管收缩。 Septic shock is caused by a Gram-positive or -negative bacterial infection. Shock is determined by a systolic blood pressure of less than 90 mph Hg. Systolic blood pressure in patients with hypertension has been reduced by more than 50 m m Hg. About 1 ╱ 3 bacteremia patients may have septic shock. Clinical characteristics often and other types of shock is different, in the absence of hypotension followed by the first chills, the patient can be warm to find state without peripheral vasoconstriction.
