Nosocomial infections are among the leading causes of mortality and morbidity in neonatal intensive care units. Prevention of healthcare-associated infections is based on strategies that aim to limit susceptibility to infections by enhancing host defences, interrupting trasmission of organisms by healthcare workers and by promoting the judicious use of antimicrobials. Strategies for the prevention of nosocomial infections include hand hygiene practices, prevention of central venous (cvc)-related bloodstream infections, judicious use of antimicrobials for therapy, enhancement of host defences, skin care and early enteral feeding with human milk. Major concerns about the use of alcoholic chlorhexidine are for the high risk of skin burns in extremely premature infants during the first days of life, when the skin is thin and not fully keratinesed. Aqueous chlorhexidine could be less irritant when used in very low birthweigth infants and thus could represent a good option. A recent prospective trial of adult patients showed similar effectiveness of alcoholic and aqueos solutions of chlorexidine. However, to date no study evaluated whether the aqueos formulation is less harmful and as effective as the alcoholic formulation in neonatal infants. The lack of evidence for neonatal patients prompts urgent need for large randomised controlled trials comparing effectiveness and safety of different skin disinfectants before CVC placement in neonates and particulary in very low birth-weight infants. Nosocomial infections are still of the most serious problems for the neonatal intensive care unit. Therefore every effort must be implemented to reduce the incidence of these infections, can not be considered a toll required hospitalization, as it may not be acceptable for a place of shelter and care as the hospital may itself be a source of disease.
医院感染是新生儿重症监护病房死亡和发病的主要原因之一。医疗相关感染的预防基于旨在通过增强宿主防御、中断医护人员传播病原体以及促进抗菌药物的合理使用来限制感染易感性的策略。预防医院感染的策略包括手卫生措施、预防中心静脉导管(CVC)相关血流感染、抗菌药物治疗的合理使用、增强宿主防御、皮肤护理以及早期母乳喂养。对使用氯己定醇的主要担忧是在生命最初几天,极低体重儿皮肤薄且未完全角化时,发生皮肤烧伤的风险高。当用于极低出生体重儿的时候,水性氯己定可能刺激性较小,因此可能是一个不错的选择。最近一项针对成年患者的前瞻性试验表明,氯己定醇溶液和水溶液的效果相似。然而,迄今为止,尚无研究评估水性制剂在新生儿中是否危害较小且与醇性制剂效果相同。由于缺乏针对新生儿患者的证据,迫切需要进行大型随机对照试验,比较不同皮肤消毒剂在新生儿尤其是极低出生体重儿放置中心静脉导管前的有效性和安全性。医院感染仍然是新生儿重症监护病房最严重的问题之一。因此,必须尽一切努力降低这些感染的发生率,不能将其视为住院所需付出的代价,因为对于像医院这样本可能是疾病来源的庇护和护理场所而言,这可能是不可接受的。
