目的:评估入住PICU 6 h内血清CRP及PCT水平在脓毒症血流感染及其他部位感染患儿临床诊断中的价值。方法:回顾性分析2010年1月至2012年1月期间,中国医科大学附属盛京医院PICU收治的30名明确诊断SIRS患儿,脓毒症血流感染及脓毒症其他部位感染患儿各15名,收集入住6 h内的血清CRP、PCT及D-二聚体含量资料,进行差异性比较并通过ROC曲线分析其诊断价值。结果:脓毒症血流感染组患儿的血清CRP及PCT水平较脓毒症其他部位感染组显著升高(P0.05)。血清PCT水平较CRP水平在诊断与鉴别脓毒症血流感染与其他部位感染性疾病方面有明显优势,PCT10 ng/mL时诊断脓毒症血流感染具有较高的可信度(阳性预测值:77%)。结论:入院6 h内的血清PCT水平较CRP水平在早期鉴别入住PICU脓毒症血流感染与其他部位感染患儿具有更好的诊断价值;当血清PCT水平>10 ng/mL时,脓毒症血流感染的诊断可能性较大。  相似文献

目的探讨血浆脑钠肽(BNP)及心肌肌钙蛋白I(cTnI)测定在小儿脓毒症诊断及评估中的意义。方法应用化学发光法检测47例脓毒症患儿和50例一般感染患儿入院时血浆BNP及cTnI的浓度,并选取同期入院的11例非感染患儿为对照组。结果(1)脓毒症组血浆BNP水平(ng/L)[中位数(四分位数间距)]为164.40(308.60),高于一般感染组[50.35(63.97)]及对照组[28.90(12.28)],差异有非常显著性(P〈0.01)。严重脓毒症组血浆BNP水平(ng/L)[379.88(1108.70)]高于一般脓毒症组[135.30(211.88)],差异有显著性(P〈0.05)。(2)脓毒症组血浆eTnI水平(μg/L)[中位数(四分位数间距)]为0.05(0.07),高于一般感染组[0.03(0.03)]及对照组[0.03(0.04)],差异有显著性(P〈0.05)。严重脓毒症组血浆cTnI水平(μg/L)[0.10(0.20)]高于一般脓毒症组[0.04(0.03)],差异有非常显著性(P〈0.01)。结论脓毒症患儿在除外充血性心力衰竭因素时,血浆BNP及cTnI水平有助于临床医生对脓毒症进行诊断和严重程度评估。  相似文献

Sepsis in the newborn   总被引:2,自引:0,他引:2  
Infections are the single largest cause of neonatal deaths globally. According to National Neonatal Perinatal Database (2002–03), the incidence of neonatal sepsis in India was 30 per 1000 live-births; klebsiella pneumoniae and staphylococcus aureus were the two most common organisms isolated. Based on the onset, neonatal sepsis is classified into two major categories: early onset sepsis, which usually presents with respiratory distress and pneumonia within 72 hours of age and late onset sepsis, that usually presents with septicemia and pneumonia after 72 hours of age. Clinical features of sepsis are non-specific in neonates and a high index of suspicion is required for the timely diagnosis of sepsis. Although blood culture is the gold standard for the diagnosis of sepsis, culture reports would be available only after 48–72 hours. A practical septic screen for the diagnosis of sepsis has been described and some suggestions for antibiotic use have been included in the protocol.  相似文献

Polymerase chain reaction in rapid diagnosis of neonatal sepsis   总被引:2,自引:0,他引:2  
In a prospective study a total of hundred neonates who fulfilled the American College of Obstetrics and Gynecology's (ACOG) criteria for probable sepsis admitted to NICU of tertiary care armed forces hospital were investigated for evidence of sepsis. The investigation protocol included sepsis screen, blood culture and 1 mL of venous blood for molecular analysis by polymerase chain reaction (PCR) for bacterial DNA component encoding 16 s RNA in all cases. 100 newborns with probable sepsis were studied to evaluate the molecular diagnosis of sepsis using PCR amplification of 16 S RNA in newborns with risk factors for sepsis or those who have clinical evidence of sepsis. We compared the results of PCR with blood culture and other markers of sepsis screen (total leucocyte count (TLC), absolute neutrophil count (ANC), immature/total neutrophil count ratio (I/T ratio), peripheral blood smear, micro ESR and C reactive protein (CRP). Controls consisted of 30 normal healthy newborns with no overt evidence of sepsis. Sepsis screen was positive in 24 (24%) of cases in study group with sensitivity and specificity of 100% and 83.5% respectively. Blood culture was positive in 09(9%t) with sensitivity of 69.2% and specificity of 100%. PCR was positive in 13(13%) of cases (9% are both blood culture and sepsis screen positive and 4% are positive by sepsis screen); the sensitivity of PCR was 100% and specificity was 95.6%. Blood culture is the most reliable method for diagnosis of neonatal sepsis. Polymerase chain reaction is useful and superior to blood culture for early diagnosis of sepsis in neonates.  相似文献

Background:  Neonatal sepsis is a severe clinical syndrome characterized by systemic signs of infection, shock and system organ failure; diagnosis is confirmed on positive culture from a normally sterile site(s). There are few reports comparing incidence, mortality, and risk factors between clinically diagnosed sepsis and that confirmed by culture.
Methods:  All infants diagnosed with early- (within first 72 h after birth) or late-onset (72 h–4 weeks after birth) neonatal sepsis between 1997 and 1999 from four neonatal centers in South Korea, were investigated.
Results:  The estimated incidence rate of neonatal sepsis during the 3 years was 30.5 per 1000 live births for clinical sepsis and 6.1 per 1000 live births for sepsis with positive culture, with case-fatality rates of 4.7% and 2.2%, respectively. When only early-onset sepsis was considered, the incidence and fatality rates were 25.1 per 1000 live births and 6.1% for clinical sepsis, and 4.3 per 1000 live births and 2.5% for culture-confirmed sepsis, respectively. For the 179 patients (185 causative organisms) of proven sepsis, Staphylococcus spp. including S. aureus were the most frequent isolates. In early-onset clinical sepsis, having very low birthweight (≤1500 g), a low Apgar score at 5 min (≤7), and being male were related to higher rates of case-fatality (relative risk: 11.3, 6.8 and 2.5, respectively)
Conclusions:  Clinical sepsis was more common than culture-confirmed sepsis and had a higher case-fatality rate. It seems prudent to take rapid and decisive steps toward better management of the high-risk group whether the sepsis is clinically diagnosed or culture confirmed.  相似文献

Sepsis in the newborn   总被引:8,自引:0,他引:8  
Systemic infection in the newborn is the commonest cause of neonatal mortality. Data from National Neonatal Perinatal Database 2000 suggest thatKlebsiella pneumoniae andStaphylococcus aureus are the commonest causes of neonatal sepsis in India. Two forms of clinical presentations have been identified. Early onset sepsis, probably related to perinatal risk factors, usually presents with respiratory distress and pneumonia whthin 72 hours of age. Late onset sepsis, related to hospital acquired infections, usually presents with septicemia and pneumonia after 72 hours of age. Clinical features of sepsis are non-specific in neonates and a high index of suspicion is required for the timely diagnosis of sepsis. Although blood culture is the gold standard for the diagnosis of sepsis, reports are available after 48–72 hours. A practical septic screen for the diagnosis of sepsis has been described and some suggestions for antibiotic use have been included in the protocols.  相似文献

AIM: To determine whether sepsis caused by coagulase-negative staphylococci (CoNS) is a risk factor for developing bronchopulmonary dysplasia (BPD) in premature newborns. METHODS: All newborns born at < or = 30 wk of gestation at Orebro University Hospital during 1994-2001 with clinical sepsis caused by CoNS (group A, n = 22) or by other bacteria (group B, n = 17) were included and compared with premature newborns without sepsis (group C, n = 53). Clinical sepsis was defined as a positive blood culture (monoculture) plus clinical symptoms and laboratory findings. BPD was defined as treatment with oxygen > 21% for at least 28 d. RESULTS: The incidence of BPD differed between the three groups, as follows: CoNS sepsis (A) 64%, other sepsis (B) 41% and control (C) 24%. The difference between the control group and the sepsis groups was highly significant (p = 0.006). In a univariate model the crude estimates of relative risk (RR) for occurrence of BPD increased with presence of sepsis and particularly with presence of sepsis with CoNS (A: RR 2.6, 95% CI 1.5-4.6, p = 0.001; B: RR 1.7, CI 0.8-3.5, p = 0.17). When regression was performed with two additional predictive variables in multivariate models including sepsis, gestational age and mechanical ventilation (group A: RR 1.5, CI 1.1-2.0, p = 0.004; group B: RR 0.9, CI 0.6-1.4, p = 0.67), the estimates were lower. CONCLUSION: The relative risk for BPD is significantly increased in premature newborns with sepsis caused by CoNS compared with those with sepsis caused by other bacteria and compared with premature newborns with no sepsis.  相似文献
