Abstract

The health of the hospital associated persons, particularly those dealing directly with insertion of devices, are serious cause of concern for hospitals. In this study, the most prevalent organism on the surface of medical devices in PICU were CoNS (16.66%) and Staphylococcus aureus (16.66%), while in NICU the most prevalent organism was Klebsiella spp. (11.25%) among Entero-bacteriaceae group followed by Acinetobacter baumannii (10%), Escherichia coli (2.5%), CoNS (6.25%), S. aureus (6.25%) and Enterococcus faecalis (6.25%). The most common species identified from blood specimen of clinical samples shows the maximum presence of Candida sp. (60/135) followed by A. baumannii (21/135), Klebsiella Pneumoniae (20/135), Enterococci (12/135), Burkholderia cepacia complex (8/135), S. aureus (6/135), E. coli (5/135), Pseudomonas aeruginosa (3/135). Different antibiotics have been used against these micro-organisms; but Cotrimoxazole, Vancomycin have been found more effective against CoNS bacteria, Clindamycin, Tetracycline for S. aureus, Nitofurantoin for Acinetobacter, and for E. faecalis, A. baumanii, and Klebsiella, erythromycin, Colistin, and Ceftriaxone have been found more effective respectively.

摘要

医院相关人员的健康，特别是那些直接处理器械插入的人员的健康，是医院严重关注的问题。在这项研究中，PICU 中医疗器械表面最常见的生物体是 CoNS（16.66%）和金黄色葡萄球菌（16.66%），而在 NICU 中，肠杆菌科中最常见的生物体是克雷伯菌属（11.25%），其次是鲍曼不动杆菌（10%）、大肠杆菌（2.5%）、CoNS（6.25%）、金黄色葡萄球菌（6.25%）和粪肠球菌（6.25%）。从临床样本的血液标本中鉴定出的最常见的物种表明，念珠菌属（60/135）的存在最多，其次是鲍曼不动杆菌（21/135）、肺炎克雷伯菌（20/135）、肠球菌（12/135）、洋葱伯克霍尔德菌复合体（8/135）、金黄色葡萄球菌（6/135）、大肠杆菌（5/135）、铜绿假单胞菌（3/135）。已经使用了不同的抗生素来对抗这些微生物；但发现复方新诺明、万古霉素对 CoNS 细菌更有效，克林霉素、四环素对金黄色葡萄球菌有效，呋喃妥因对不动杆菌有效，而对于粪肠球菌、鲍曼不动杆菌和克雷伯菌，红霉素、粘菌素和头孢曲松分别更有效。
