dysfunction or tissue hypoperfusionSeptic shock：sepsis-induced hypotension persisting despite adequate fluid resuscitationSepsis-induced tissue hypoperfusion：infection-induced hypotension,elevated lactate,or oliguria.Sepsis-induced hypotension：SBP 90 mm Hg or MAP 40 mm Hg or less than two standard deviations below normal for age in the absence of other causes of hypotension.Crit Care Med,2013,41(2):580-637Diagnostic Criteria for SepsisInfection,documented or suspected,and some of the following:General variablesFever(38.3C)Hypothermia(core temperature 90/min1 or more than two SD above the normal value for ageTachypneaAltered mental statusSignificant edema or positive fluid balance(20 mL/kg over 24 hr)Hyperglycemia(plasma glucose 140 mg/dL or 7.7 mmol/L)in the absence of diabetesDiagnostic Criteria for SepsisInflammatory variablesLeukocytosis(WBC count 12,000 L1)Leukopenia(WBC count 4000 L1)Normal WBC count with greater than 10%immature formsPlasma C-reactive protein more than two sd above the normal valuePlasma procalcitonin more than two sd above the normal valueHemodynamic variablesArterial hypotension(SBP 90 mm Hg,MAP 40 mm Hg in adults or less than SD below normal for age)Diagnostic Criteria for SepsisOrgan dysfunction variablesArterial hypoxemia(Pao2/Fio2 300)Acute oliguria(urine output 0.5 mg/dL or 44.2 mol/LCoagulation abnormalities(INR 1.5 or aPTT 60 s)Ileus(absent bowel sounds)Thrombocytopenia(platelet count 4 mg/dL or 70 mol/L)Tissue perfusion variablesHyperlactatemia(1 mmol/L)Decreased capillary refill or mottlingDiagnostic Criteria for Sepsispediatric population signs and symptoms of inflammation infection hyper-or hypothermia(rectal temperature 38.5 or 35C),tachycardia(may be absent in hypothermic patients),and at least one of the following indications of altered organ function:altered mental status hypoxemiaincreased serum lactate levelbounding pulsesSevere SepsisSevere sepsis definition=sepsis-induced tissue hypoperfusion or organ dysfunction(any of the following thought to be due to the infection)Sepsis-induced hypotensionLactate above upper limits laboratory normalUrine output 0.5 mL/kg/hr for more than 2 hrs despite adequate fluid resuscitationAcute lung injury with Pao2/Fio2 250 in the absence of pneumonia as infection sourceAcute lung injury with Pao2/Fio2 2.0 mg/dL(176.8 mol/L)Bilirubin 2 mg/dL(34.2

information on a particular clinical topic.Guidelines also represent the best available synthesis of contemporary knowledge in this area,and for this reason we believe they must be promoted.Implementation of a sepsis intervention program as a standard of care in a typical hospital protocol leads to improvements in processes of care.指南Guidelines are not a compilation of truths.Guidelines are not rules.Guidelines do not establish legal standards of practice.A strong rating for any particular recommendation does not preclude further research.Critical Care 2008,12:162Guidelines are the product of an explicit,systematic approach to the evaluation and synthesis of available information on a particular clinical topic.Their reliability depends on three factorsthe extent to which all relevant evidence is sought for evaluationthe quality of the available evidencethe rigour of the evaluation process usedGRADEGrading of Recommendations,Assessment,Development,and Evaluation methodology which assigns a measure of the strength of the recommendation based not only on the evidence,but also on factors such as cost,plausibility,toxicity,and clinician acceptance.This method provides a more nuanced synthesis of data and,in the current guidelines,the strength of recommendation was established through a formal voting process,in recognition of the fact that in many areas participants had divergent interpretations of the evidence.a strong Grading of Recommendations,Assessment,Development,and Evaluation recommendation had to receive the support of at least 80%of the participants.常用血管活性药物药物物配置配置用法用法注意点注意点多巴胺NS 50ml+多巴胺200mg初始剂量3-5ug/kg/min，每次调整1-2ug/kg/min，极量20ug/kg/min。如与去甲肾上腺素联用升压，一般维持在7-10ug/kg/min心动过速、心律失常慎用多巴酚丁胺NS 50ml+多巴酚丁胺200mg初始剂量3-5ug/kg/min，每次调整1-2ug/kg/min，极量20ug/kg/min。心动过速、心律失常慎用去甲肾上腺素NS 50ml+去甲肾上腺素20mg初始剂量0.1-0.2ug/kg/min，每次调整0.1ug/kg/min，极量2-3ug/kg/min。避免漏出血管外，如有漏出，NS10-15ml+酚托拉明5-10mg,局部封闭，防止坏死肾上腺素NS 50ml+肾上腺素20mg初始剂量0.1ug/kg/min，每次调整0.05-0.1ug/kg/min谢谢大家谢谢大家
