Neonatal sepsis is a major cause of morbidity and mortality globally. The aim of this study was to assess admission outcome and antimicrobial susceptibility pattern of bacterial isolates among neonates with suspected sepsis at the Dessie Comprehensive specialized Hospital (DCSH), Northeastern Ethiopia.
Cross-sectional study was conducted from August 2017 to March 2018. Two hundred forty-six neonates were recruited, and each patient's blood specimen was collected aseptically using bottle containing Brain Heart Infusion for blood culture. Both clinical and laboratory data such as bacterial culture growth and antimicrobial susceptibility pattern were collected from the neonate; clinical data from the mothers were also included. Antimicrobial susceptibility testing was performed using Kirby-Bauer disk diffusion method. The data were analyzed using SPSS version 20.
Bacteria were identified from 67 (27.2%) blood cultures. The predominant pathogen was (35.8%) followed by (26.8%), and Coagulase Negative (CoNS) (19.4%). The isolated bacteria showed resistance to Ampicillin 55 (82%), third-generation Cephalosporins 21 (58.3%) and other tested antimicrobials. Overall, 68.6% bacterial isolates demonstrated Multidrug resistance (MDR) and total registered mortality rate was 12/246 (4.8%). Both neonatal factors such as neonatal temperature, septic umbilicus and utilization of indwelling medical device during delivery; and maternal factors such as age, antenatal urinary tract infection (UTI), mode of delivery and prolonged rupture of membrane (PROM) had shown statistically significant association with bacterial sepsis.
The rate of bacterial growth was found to be high; and were the predominant organisms. Both maternal and neonatal related data were strong predictors for bacterial infection of the neonate. Therefore, improving infrastructures for screening of bacteremia as well as active surveillance in clinical setting needed to ensure proper empirical therapy.
新生儿败血症是全球发病和死亡的主要原因。本研究的目的是评估埃塞俄比亚东北部德西综合专科医院(DCSH)疑似败血症新生儿的入院结局及细菌分离株的抗菌药物敏感性模式。
于2017年8月至2018年3月进行横断面研究。招募了246名新生儿,无菌采集每位患者的血液标本,使用含有脑心浸液的瓶子进行血培养。收集新生儿的临床和实验室数据,如细菌培养生长情况和抗菌药物敏感性模式;还包括母亲的临床数据。采用 Kirby-Bauer 纸片扩散法进行抗菌药物敏感性试验。使用SPSS 20版对数据进行分析。
从67份(27.2%)血培养中鉴定出细菌。主要病原体为[具体细菌名称1](35.8%),其次是[具体细菌名称2](26.8%)和凝固酶阴性葡萄球菌(CoNS)(19.4%)。分离出的细菌对氨苄西林耐药55株(82%),对第三代头孢菌素耐药21株(58.3%)以及对其他测试抗菌药物耐药。总体而言,68.6%的细菌分离株表现出多重耐药(MDR),总登记死亡率为12/246(4.8%)。新生儿因素如新生儿体温、脐部感染和分娩期间使用留置医疗器械;以及母亲因素如年龄、产前尿路感染(UTI)、分娩方式和胎膜早破(PROM)与细菌性败血症均显示出统计学上的显著关联。
发现细菌生长率较高;[具体细菌名称1]和[具体细菌名称2]是主要病原体。母亲和新生儿相关数据均是新生儿细菌感染的有力预测因素。因此,需要改善菌血症筛查基础设施以及临床环境中的主动监测,以确保适当的经验性治疗。
