血培养在产房微生物检测中的作用分析

The role of blood culture in the delivery room microbiological detection analysis

目的：对血培养在产房婴儿微生物检测中的作用进行分析研究。方法抽取2013年1月～2014年1月本院妇产科住院的新生儿56例作为研究对象，通过BACT/ALERT120全自动血培养仪，对血培养检出的病原菌及药敏试验结果进行分析。结果所有56份血培养标本中，检出革兰阳性球菌34份，占60.7%，检出革兰阴性杆菌22例，占64.7%，其中革兰阳性球菌包括凝固酶阴性葡萄球菌、金黄色葡萄球菌、金黄色葡萄球菌、口腔链球菌以及肺炎链球菌；革兰阴性杆菌包括大肠埃希菌、肺炎克雷伯菌、宝石不动杆菌以及阴沟肠杆菌；革兰阳性球菌中以凝固酶阴性葡萄球菌为主，对青霉素G的耐药率可达到89.2%，对克林霉素的耐药率为38.5%；革兰阴性杆菌对阿莫西林、提卡西林、复方新诺明的耐药率分别是82.3%、75.6%、52.4%。结论血培养阳性率较高，且具有诸多耐药性，因此展开对学培养的研究，及时为临床诊断提供可参考依据，能够进一步降低耐药菌株的产生。

Objective On the role of blood culture in the delivery room baby microbial detection analysis. Methods extract from January 2013 to January 2014 in our hospital obstetrics and gynecology hospital neonatal 56 cases as the research object, through the BACT/ALERT120 automatic blood culture instrument, detection of blood culture pathogens and drug susceptibility test results are analyzed. Results All the 56 a specimen of blood culture, check out the gram positive coccus, 34 （60.7%）, 22 cases detected gram-negative bacillus and accounted for 64.7%, including gram-positive cocci coagulase negative staphylococcus aureus, staphylococcus aureus, staphylococcus aureus and streptococcus pneumoniae, oral streptococcus; Gram-negative bacteria, including e. coli, klebsiella pneumoniae, gem acinetobacter and sewer e. coli; The gram positive coccus is given priority to with coagulase negative staphylococcus, irologic resistance to penicillin G can reach 89.2%, prevalence of clindamycin resistance is 38.5%; Gram-negative bacilli to amoxicillin and card Westwood, and compound new Ming ni is 82.3%, 75.6% and 82.3% respectively. Conclusion Blood culture positive rate is higher, and it has a lot of resistance, so the research on learning training, in a timely manner to provide reference for clinical diagnosis, can further reduce the generation of drug-resistant strains.
