Neonatal sepsis remains one of the leading causes of mortality and morbidity in developing countries. With a dearth of data on neonatal sepsis in our country, this study was conducted to determine the incidence of clinical neonatal sepsis and evaluate the clinical, bacteriological, and antimicrobial susceptibility profile of organisms. . A prospective cross-sectional study was conducted in the Neonatal Unit of the National Hospital from 1 January to 31 December 2016. All neonates admitted with suspected clinical sepsis were included. Sepsis screens and cultures were sent under aseptic conditions. Data was analyzed using STATA™ version 12. Clinical features and neonatal and maternal risk factors were analyzed using chi-squared test. Bacteriological profile was analyzed with descriptive statistics.
During the study period, incidence of culture positive neonatal sepsis was 19 per 1000 admissions with a blood culture positivity rate of 14%. 54.5% had culture-positive early-onset sepsis (EOS). Prematurity ( = 0.012), APGAR < 6 ( = 0.018), low birth weight ( < 0.001), and maternal intrapartum antibiotics ( = 0.031) significantly increased risk for culture-positive EOS. Prematurity ( < 0.001), low birth weight ( = 0.001), and parental nutrition ( = 0.007) were significantly associated with increased risk of culture-positive late-onset sepsis. A positive screen had sensitivity of 81.8% and negative predictive value of 87.7%. Gram-negative organisms were most commonly isolated (64.6%). Coagulase-negative (31%) were the commonest isolate followed by (27%) and (18.8%). Ninety percent of were carbapenem resistant. Gram-negative sepsis had mortality of 88.9%.
Preterm, low birth weight, low APGAR scores, intrapartum antibiotics, and parental nutrition were significantly associated with neonatal sepsis. Coagulase-negative , , and were the principal causative organisms. Gram-negative organisms had high resistance to commonly used antibiotics.
在发展中国家,新生儿败血症仍然是导致死亡和发病的主要原因之一。由于我国缺乏有关新生儿败血症的数据,因此开展了本研究以确定临床新生儿败血症的发病率,并评估病原体的临床、细菌学及抗菌药物敏感性特征。2016年1月1日至12月31日,在国立医院新生儿科进行了一项前瞻性横断面研究。纳入所有因疑似临床败血症入院的新生儿。在无菌条件下送检败血症筛查及培养样本。使用STATA™ 12版软件进行数据分析。采用卡方检验分析临床特征以及新生儿和母亲的危险因素。用描述性统计方法分析细菌学特征。
在研究期间,培养阳性的新生儿败血症发病率为每1000例入院病例中有19例,血培养阳性率为14%。54.5%的患儿为培养阳性的早发型败血症(EOS)。早产(P = 0.012)、阿氏评分<6分(P = 0.018)、低出生体重(P<0.001)以及母亲产时使用抗生素(P = 0.031)显著增加了培养阳性EOS的风险。早产(P<0.001)、低出生体重(P = 0.001)以及肠外营养(P = 0.007)与培养阳性的晚发型败血症风险增加显著相关。筛查阳性的敏感度为81.8%,阴性预测值为87.7%。革兰阴性菌是最常分离出的病原体(64.6%)。凝固酶阴性葡萄球菌(31%)是最常见的分离菌株,其次是大肠杆菌(27%)和克雷伯菌(18.8%)。90%的大肠杆菌对碳青霉烯类耐药。革兰阴性菌败血症的死亡率为88.9%。
早产、低出生体重、低阿氏评分、产时抗生素使用以及肠外营养与新生儿败血症显著相关。凝固酶阴性葡萄球菌、大肠杆菌和克雷伯菌是主要病原体。革兰阴性菌对常用抗生素具有高度耐药性。
