Abstract
Neonatal sepsis is associated with severe morbidity and mortality in the neonatal period. Clinical manifestations range from subclinical infection to severe local or systemic infection. Neonatal sepsis is divided into three groups as early-onset neonatal sepsis, late-onset neonatal sepsis and very late-onset neonatal sepsis according to the time of the onset. It was observed that the incidence of early-onset neonatal sepsis decreased with intrapartum antibiotic treatment. However, the incidence of late-onset neonatal sepsis has increased with the increase in the survival rate of preterm and very low weight babies. The source of the causative pathogen may be acquisition from the intrauterine origin but may also acquisition from maternal flora, hospital or community. Prematurity, low birth weight, chorioamnionitis, premature prolonged rupture of membranes, resuscitation, low APGAR score, inability to breastfeed, prolonged hospital stay and invasive procedures are among the risk factors. This article reviews current information on the definition, classification, epidemiology, risk factors, pathogenesis, clinical symptoms, diagnostic methods and treatment of neonatal sepsis.

Abstract
Infants in the neonatal intensive care unit are highly susceptible to healthcare associated infections (HAI), with a substantial impact on mortality, morbidity and healthcare costs. Effective skin disinfection with topical antiseptic agents is an important intervention in the prevention or reduction of HAI. A wide array of antiseptic preparations in varying concentrations and combinations has been used in neonatal units worldwide. In this article we have reviewed the current evidence of a preferred antiseptic of choice over other agents for topical skin disinfection in neonates. Chlorhexidine (CHG) appears to be a promising antiseptic agent; however there exists a significant concern regarding the safety of all agents used including CHG especially in preterm and very low birth weight infants. There is substantial evidence to support the use of CHG for umbilical cord cleansing and some evidence to support the use of topical emollients in reducing the mortality in infants born in developing countries. Well-designed large multicentre randomized clinical trials are urgently needed to guide us on the most appropriate and safe antiseptic to use in neonates undergoing intensive care, especially preterm infants.

Abstract
PURPOSE OF REVIEW Neonates in intensive care are more susceptible to sepsis. Infection is commonly acquired via the transcutaneous portal. It is necessary to identify the most effective yet safest topical antiseptics for use in neonates to reduce nosocomial sepsis. RECENT FINDINGS Recent national surveys indicate that a wide range of topical antiseptic preparations are used in the neonatal nursery. There are very few comparative studies in neonates and no robust evidence in favour of any particular antiseptic. There are significant safety and potential toxicity issues for neonates with all the commonly used antiseptics, particularly in very small immature babies. There are no convincing roles for routine application of emollient creams on the skin, topical antiseptics on the umbilical stump, or maternal vaginal washes with chlorhexidine for the prevention of neonatal infection. SUMMARY Large multicentre trials are needed to determine the optimal antiseptic to use for neonates undergoing intensive care, especially for extremely preterm infants.

Abstract
Central venous catheter infections are the leading cause of healthcare-associated bloodstream infections and contribute significantly to mortality and morbidity in neonatal intensive care units. Moreover, infection poses significant economic consequence which increased hospital costs and increased length of hospital stay. Prevention strategies are detailed in guidelines published by the Centers for Disease Control and Prevention (CDC) in the United States; nevertheless, recent surveys in neonatal units in the United States, and Australia and New Zealand demonstrate these are not always followed. This review discusses the numerous evidence-based strategies to prevent catheter infections including hand hygiene, maximal sterile barriers during insertion, skin disinfection, selection of insertion site, dressings, aseptic non-touch technique, disinfection of catheter hubs/ports, administration set management, prompt removal of catheter, antibiotic locks, systemic antibiotic prophylaxis and chlorhexidine bathing. Furthermore, it will describe different strategies that can be implemented into clinical practice to reduce infection rates. These include the use of care bundles including checklists, education and the use of CVC teams.

Abstract
Introduction: Skin physiology of neonates and preterm infants and evidence-based skin care are not well explored for health care providers. Aim: The aim of our present study was to investigate the skin care methods of the tertiary Neonatal Intensive Care Units in Hungary. Method: A standardized questionnaire was distributed among the 22 tertiary Neonatal Intensive Care Units with questions regarding skin care methods, bathing, emollition, skin disinfection, umbilical cord care, treatment of diaper dermatitis, and use of adhesive tapes. Results: The skin care methods of the centres were similar in several aspects, but there were significant differences between the applied skin care and disinfectant products. Conclusions: The results of this survey facilitate the establishment of a standardized skin care protocol for tertiary Neonatal Intensive Care Units with the cooperation of dermatologists, neonatologists and pharmacists.

Abstract
BACKGROUND The use of central venous catheters has permitted lifesaving treatment for critically ill neonates; however, the attributable mortality rate for central line-associated bloodstream infections (CLABSIs) has been estimated to be between 4% and 20%. In 2006/2007, the authors' neonatal intensive care unit (NICU) had a CLABSI rate that was nearly twofold higher than that reported by other Canadian NICUs. OBJECTIVE To implement a quality improvement collaborative to reduce the incidence of neonatal CLABSI. METHODS A retrospective observational study was performed to compare CLABSI in neonates admitted to the authors' level III NICU between August 2007 and March 2011. The entire study period was divided into four time periods to evaluate secular trends. A comprehensive catheter-related bloodstream infection prevention initiative was implemented in August 2007. The initiatives included staff education, standardization of skin preparation protocol, introduction of new antiseptic agents, implementation of central catheter insertion and maintenance checklists, reinforcement of the use of maximal sterile barrier precautions, and revision of the central catheter configuration and maintenance protocols. RESULTS The median CLABSI rate of 7.9 per 1000 catheter days at the beginning of the study (period 1 [August 2007 to June 2008]) gradually decreased over the entire study period (P=0.034): period 2 (July 2008 to May 2009), 3.3 per 1000 catheter days; period 3 (June 2009 to April 2010), 2.6 per 1000 catheter days; and period 4 (May 2010 to March 2011), 2.2 per 1000 catheter days. CONCLUSION A multidisciplinary evidence-based quality improvement collaborative resulted in a significant reduction in the CLABSI rate. Continuous quality improvement measures are required to reduce catheter-related bloodstream infections among low-birth-weight infants.

Abstract
Early-onset sepsis remains a major diagnostic problem in neonatal medicine. Definitive diagnosis depends on cultures of blood or other normally sterile body fluids. Abnormal hematological counts, acute-phase reactants, and inflammatory cytokines are neither sensitive nor specific, especially at the onset of illness. Combinations of measurements improve diagnostic test performance, but the optimal selection of analytes has not been determined. The best-established use of these laboratory tests is for retrospective determination that an infant was not infected, based on failure to mount an acute-phase response over the following 24 to 48 hours.

Abstract
Advances in neonatology now support the survival of the tiniest of infants. The peripherally inserted central catheter (PICC) has now become an integral part of routine practice in neonatal intensive care units around the world. Keen attention to safe maintenance of these devices is essential. A properly applied and maintained PICC dressing is the first line of defense to minimize the risk of complications such as dislodgement, migration, and infection. This article describes a neonatal PICC dressing change and discusses the frequently encountered quandaries surrounding this important procedure, including dressing materials, frequency, site preparation, barrier precautions, and other relevant concerns.

Abstract
BACKGROUND Chlorhexidine cleansing of newborn skin is a highly promising intervention for reducing neonatal mortality in developing countries, yet little is known of the mechanism of action. This study examined the impact of a single skin cleansing of hospitalized newborn infants in Bangladesh with baby wipes containing 0.25% chlorhexidine on both qualitative and quantitative skin flora. METHODS Within 72 hours of birth, the skin of newborns admitted to Dhaka Shishu Hospital was wiped with baby wipes containing 0.25% chlorhexidine (n = 67) or placebo (n = 66) solution. Skin condition was assessed and skin swabs were taken from 3 sites (axillary, peri-umbilical, inguinal) at baseline and 2 hours, 24 hours, 3 days and 7 days after treatment. Skin flora was quantified and colonizing species were identified. FINDINGS Skin cleansing with chlorhexidine had no adverse effects on skin condition, and resulted in minimal reduction (mean 0.5 degrees C) in body temperature. Positive skin culture rates 2 hours after skin cleansing were approximately 35%-55% lower than the baseline rates for placebo and chlorhexidine groups at all 3 sites. For the chlorhexidine group, positive skin culture rates remained significantly lower than the baseline rates for 24 hours to 3 days, whereas for the placebo group, beyond the first 2-hour follow-up, these values were not lower than baseline in any of the 3 sites. INTERPRETATION Chlorhexidine skin treatment produced more extended skin cleansing effects than the placebo treatment. It is possible that the quantitative and qualitative reductions observed in the skin flora might contribute to reducing neonatal infections.

Abstract
BACKGROUND The optimal number of blood cultures needed to document sepsis in an ill neonate has undergone little critical evaluation. Multiple site cultures may improve pathogen detection if intermittent bacteremia occurs, or if a low density of bacteria is present in the blood. We hypothesized, however, that bacterial clearance is slower and bacteremia more continuous in septic neonates, so that a single site blood culture should be sufficient to accurately document true septicemia. OBJECTIVE To determine the need for multiple site blood cultures in the evaluation of neonates for sepsis. DESIGN/METHODS Clinical data were prospectively collected for 216 neonates who had 269 pairs of blood cultures taken from two different peripheral sites for the evaluation of possible sepsis. A minimum of 1 ml of blood was obtained from the two peripheral sites within 15-30 min of each other. Based on prior retrospective data, we determined that 203 infants would need to have two site blood cultures to demonstrate a significant improvement in pathogen detection at an alpha of 0.05 and a beta of 0.20 (80%) power. RESULTS A total of 186 culture pairs were taken for evaluation of early-onset sepsis in 186 neonates, while 83 pairs were drawn for evaluation of late-onset sepsis in 43 neonates. In all, 21 neonates from the late-onset group were evaluated more than once, and 12 neonates were evaluated for both early- and late-onset sepsis. In all, 20 (9.2%) of 216 neonates had 22 episodes of culture-proven sepsis at a median age of 18 days. All neonates with positive cultures had the same organism with a similar sensitivity pattern obtained from the two different peripheral sites. The other 196 study neonates had negative blood cultures from both sites. The single episode of early-onset sepsis was caused by Listeria monocytogenes, while all remaining episodes were late-onset with the following organisms: Staphylococcus epidermidis (7), methicillin-resistant Staphylococcus aureus (MRSA) (3), combined MRSA and Candida albicans (2), Candida albicans alone (2), late-onset Group B beta-hemolytic Streptococcus (GBS) (2), Klebsiella pneumoniae (2), Enterococcus fecalis (1), Escherichia coli (1), and Serratia marcescens (1). Since no infant grew organisms from only one of the two sites, the data indicate that the diagnosis of sepsis would have been made correctly in all infants with a single site culture. CONCLUSIONS Two site blood cultures for the initial evaluation of neonatal sepsis do not have a better yield in pathogen detection. Sepsis in neonates can be detected with no loss of accuracy with a single site blood culture with blood volume of>or=1 ml.

Abstract
AIM The finding that 10% povidone-iodine skin disinfectant may compromise thyroid function in premature infants prompted its replacement with 0.5% chlorhexidine gluconate solution in 70% isopropanol. The objective of this study was to compare the incidence rates of true infection and contamination associated with the use of these two disinfectants in the neonatal intensive care unit. METHODS The study population comprised two cohorts of infants admitted to our neonatal intensive care unit: 1) in 1992-1993 when only 10% povidone-iodine was used as a skin disinfectant, and 2) in 1995-1996 when only 0.5% chlorhexidine gluconate solution in 70% isopropanol was used. A retrospective chart review was conducted to determine whether all documented positive blood, CSF and suprapubic aspirate cultures indicated true infection or contamination. True infection was defined as clinical symptoms and/or laboratory abnormalities suggestive of sepsis, with positive blood, CSF or suprapubic aspirate cultures. RESULTS 1146 infants were admitted during the study periods, 507 during the first period and 639 during the second. In the early group, 17.6% of infants had major malformations, 72.0% were premature and 25.2% had weights of < 1500 g. Corresponding percentages for the latter group were 16.0%, 80.6% and 32.9%, respectively. No statistically significant differences were found between the two research periods in rate of infants with positive blood cultures, true infections, or contamination. CONCLUSION The use of 0.5% chlorhexidine gluconate solution in 70% isopropanol as a skin disinfectant is justified in neonatal intensive care units because it is not associated with an increased incidence of infections as opposed to 10% povidone-iodine and is devoid of detrimental effects.

Abstract
Nosocomial sepsis is a serious problem for neonates who are admitted for intensive care. As it is associated with increases in mortality, morbidity, and prolonged length of hospital stay, both the human and fiscal costs of these infections are high. Although the rate of nosocomial sepsis increases with the degree of both prematurity and low birth weight, no specific lab test has been shown to be very useful in improving our ability to predict who has a "real" blood-stream infection and, therefore, who needs to be treated with a full course of antibiotics. As a result, antibiotic use is double the rate of "proven" sepsis and we are facilitating the growth of resistant organisms in the neonatal intensive care unit. The purpose of this article is to review the topic of nosocomial infections in neonates.

Abstract
OBJECTIVE To determine the effect of implementing an evidence-based hand washing policy on between-patient hand washing compliance and on blood and cerebrospinal fluid (CSF) culture rates in a level III neonatal intensive care unit (NICU). METHODS An evidence-based hand washing policy, supported by an intensive education program, was introduced in a regional NICU. A total of 2009 preintervention neonates (16,168 patient days) over 17 months were compared to 676 postintervention neonates (5779 patient days) over 6 months. Hand washing compliance and rates of blood and CSF cultures yielding coagulase negative staphylococci (CONS) were compared before and after intervention. RESULTS Compliance with appropriate between-patient hand washing improved (from 47.4% to 85.4%, p=0.001) after the hand washing policy was introduced. The rate of cultures positive for CONS declined from 6.1+/-2.3 to 3.2+/-1.6 per 1000 patient days (p=0.005). Most of this reduction was attributable to a reduction in false-positive cultures, from 4.2+/-2.4 to 1.9+/-1.8 per 1000 patient days (p=0.042), but there was a trend toward decreased true-positive cultures (from 2.1+/-1.2 to 1.2+/-1.0 per 1000 patient days, p=0.074) as well. Potential confounders and demographics factors were similar between the control and intervention subjects. CONCLUSION Implementation of an evidence-based hand washing policy resulted in a significant increase in hand washing compliance and a significant decrease in false-positive coagulase negative staphylococcal blood and CSF culture rates. Exploratory data analysis revealed a possible effect on true-positive coagulase negative staphylococcal blood and CSF culture rates, but these results need to be confirmed in future studies.

Abstract
The relative importance of neonatal health and neonatal skin care has been highlighted in recent years as infant mortality rates have decreased while death rates during the neonatal period remain unacceptably high in many areas of the world. During the neonatal period, many newborns develop preventable, clinically apparent skin problems, and many more, especially preterm neonates, experience morbidity caused by compromised skin barrier integrity. Several strategies are available for protecting the integrity and promoting the hygiene of the skin and augmenting its function as a barrier to TEWL and heat loss and the entrance of infectious or toxic agents. Research defining optimal applications of many of these strategies, however, and the development of new approaches in skin care is one of the greatest challenges in pediatric dermatology and holds promise for improving neonatal outcome in the future. The ability to modulate epidermal barrier function and integrity relies largely on the topical use of protective materials and substances and manipulation of the external environment. As understanding of epidermal barrier development advances, perhaps pharmacologic manipulation of barrier development, as now practiced for augmentation of neonatal lung maturity, will become a reality. In the meantime, greater awareness among neonatal health care practitioners of state-of-the-art strategies for optimizing skin integrity in neonates is an important step toward improving neonatal health.

Abstract
OBJECTIVE To review the literature addressing the care of neonatal skin. DATA SOURCES Computerized searches in MEDLINE and CINAHL, as well as references cited in articles reviewed. Key concepts in the searches included neonatal skin differences; neonatal skin and care practices for skin integrity; neonatal skin and toxicity; permeability; and contact irritant sensitization. STUDY SELECTION Articles and comprehensive works relevant to key concepts and published after 1963, with an emphasis on new findings from 1993 to 1999. One hundred two citations were identified as useful to this review. DATA EXTRACTION Data were extracted and organized under the following headings: anatomy and physiology of the skin; physiologic and anatomic differences in neonatal skin; nutritional deficiencies; skin care practices; and care of skin breakdown. DATA SYNTHESIS Newborns' skin is at risk for disruption of normal barrier function because of trauma. In light of available evidence about differences in neonatal skin development, clinical practice guidelines are suggested for baths, lubrication, antimicrobial skin disinfection, and adhesive removal. In addition, basic care practices are suggested for maintaining skin integrity, reducing exposure to potentially toxic substances, and promoting skin health beyond the neonatal period. Preventive care recommendations are made for reducing trauma, protecting the skin's immature barrier function, and promoting skin integrity. CONCLUSIONS This review generated evidence with which to create a new and comprehensive practice guideline for clinicians. Evaluation of the guideline is under way at 58 U.S. sites.

Key concepts in the searches included neonatal skin differences; neonatal skin and care practices for skin integrity; neonatal skin and toxicity; permeability; and contact irritant sensitization. STUDY SELECTION Articles and comprehensive works relevant to key concepts and published after 1963, with an emphasis on new findings from 1993 to 1999. One hundred two citations were identified as useful to this review. DATA EXTRACTION Data were extracted and organized under the following headings: anatomy and physiology of the skin; physiologic and anatomic differences in neonatal skin; nutritional deficiencies; skin care practices; and care of skin breakdown. DATA SYNTHESIS Newborns' skin is at risk for disruption of normal barrier function because of trauma. In light of available evidence about differences in neonatal skin development, clinical practice guidelines are suggested for baths, lubrication, antimicrobial skin disinfection, and adhesive removal. In addition, basic care practices are suggested for maintaining skin integrity, reducing exposure to potentially toxic substances, and promoting skin health beyond the neonatal period. Preventive care recommendations are made for reducing trauma, protecting the skin's immature barrier function, and promoting skin integrity. CONCLUSIONS This review generated evidence with which to create a new and comprehensive practice guideline for clinicians. Evaluation of the guideline is under way at 58 U.S. sites.

Abstract
OBJECTIVE Premature infants have an ineffective epidermal barrier. The aim of this study was to investigate the cutaneous and systemic effects of preservative-free topical ointment therapy in premature infants. STUDY DESIGN We conducted a prospective, randomized study of 60 infants less than 33 weeks' estimated gestational age. The treated infants received therapy for 2 weeks with twice-daily preservative-free topical ointment therapy while the control group received no topical treatment or as-needed therapy with a water-in-oil emollient. Data collection included transepidermal water loss (TEWL) measurement, skin condition evaluations, fungal and quantitative bacterial skin cultures, analysis of fluid requirements, patterns of weight low or gain, and the incidence of blood and cerebrospinal fluid cultures positive for microorganisms. RESULTS We found that topical ointment therapy significantly decreased TEWL during the first 6 hours after the initial application. TEWL was decreased by 67% (p = 0.0001) when measured 30 minutes after application and 34% (p = 0.001) when measured 4 to 6 hours after application. We also observed significantly superior skin condition scores in the treated group on study days 7 and 14 (p = 0.001) and 0.0004, respectively). Quantitative bacterial cultures revealed significantly less colonization of the axilla on day 2, 3, or 4 and on day 14 (p = 0.008 and 0.04, respectively). The incidence of positive findings in blood and/or cerebrospinal fluid cultures was 3.3% in the treated group of infants versus 26.7% in the control group (p = 0.02). There was no statistical difference in the fluid requirements or patterns of weight gain or loss during the 2 weeks of the study. CONCLUSIONS Preservative-free topical ointment therapy decreased TEWL for 6 hours after application, decreased the severity of dermatitis, and decreased bacterial colonization of axillary skin. Infants treated with ointment had fewer blood and cerebrospinal fluid cultures positive for microorganisms. These data support the use of topical ointment therapy in very premature infants during the first weeks after birth.

Abstract
This investigation was undertaken to determine the magnitude of, and interrelations between, reservoirs of coagulase negative staphylococci on infants' skin at various sites (including sites used for insertion of intravascular catheters) and in faeces during the first six months of life. Sites with large numbers of coagulase negative staphylococci were identified by sampling 16 skin sites and stools from 20 preterm neonates at 8-30 days of life. A more detailed survey of numbers and types of coagulase negative staphylococci in stool and at six skin sites of 10 preterm infants was then performed over the first six months of life. Isolates of coagulase negative staphylococci were collected and characterised by speciation, antibiotic susceptibility profiling, and plasmid restriction fragment length polymorphism analysis. Large, relatively stable reservoirs were identified in the faeces, around the ear, and in the axilla and nares. Skin on the forearm and leg, sites at which peripheral catheters are frequently sited, carried small unstable numbers of coagulase negative staphylococci, which were usually indistinguishable from coagulase negative staphylococci isolated from other body sites on the same baby. Contamination of catheter insertion sites with coagulase negative staphylococci from reservoir sites on the same baby could explain these observations. These data suggest that interventions reducing cross-contamination between sites on the same baby might be as important in preventing coagulase negative staphylococcal bacteraemias as measures taken to prevent cross infection between babies. Procedures which are likely to result in heavy coagulase negative staphylococcal contamination of the hands of healthcare staff, such as changing soiled nappies, should receive particular attention.
