Endotracheal Tube Size Adjustments Within Seven Days of Neonatal Intubation.

BACKGROUND AND OBJECTIVES: Neonatal endotracheal tube (ETT) size recommendations are based on limited evidence. We sought to determine data-driven weight-based ETT sizes for infants undergoing tracheal intubation and to compare these with Neonatal Resuscitation Program (NRP) recommendations. METHODS: Retrospective multicenter cohort study from an international airway registry. We evaluated ETT size changes (downsizing to a smaller ETT during the procedure or upsizing to a larger ETT within 7 days) and risk of procedural adverse outcomes associated with first-attempt ETT size selection when stratifying the cohort into 200 g subgroups. RESULTS: Of 7293 intubations assessed, the initial ETT was downsized in 5.0% of encounters and upsized within 7 days in 1.5%. ETT downsizing was most common when NRP-recommended sizes were attempted in the following weight subgroups: 1000 to 1199 g with a 3.0 mm (12.6%) and 2000 to 2199 g with a 3.5 mm (17.1%). For infants in these 2 weight subgroups, selection of ETTs 0.5 mm smaller than NRP recommendations was independently associated with lower odds of adverse outcomes compared with NRP-recommended sizes. Among infants weighing 1000 to 1199 g: any tracheal intubation associated event, 20.8% with 2.5 mm versus 21.9% with 3.0 mm (adjusted OR [aOR] 0.62, 95% confidence interval [CI] 0.41-0.94); severe oxygen desaturation, 35.2% with 2.5 mm vs 52.9% with 3.0 mm (aOR 0.53, 95% CI 0.38-0.75). Among infants weighing 2000 to 2199 g: severe oxygen desaturation, 41% with 3.0 mm versus 56% with 3.5mm (aOR 0.55, 95% CI 0.34-0.89). CONCLUSIONS: For infants weighing 1000 to 1199 g and 2000 to 2199 g, the recommended ETT size was frequently downsized during the procedure, whereas 0.5 mm smaller ETT sizes were associated with fewer adverse events and were rarely upsized.

Contemporary fluid management, humidity, and patent ductus arteriosus management strategy for premature infants among 336 hospitals in Asia.

Objectives: The management of patent ductus arteriosus (PDA) is a critical concern in premature infants, and different hospitals may have varying treatment policies, fluid management strategies, and incubator humidity. The Asian Neonatal Network Collaboration (AsianNeo) collected data on prematurity care details from hospitals across Asian countries. The aim of this study was to provide a survey of the current practices in the management of PDA in premature infants in Asian countries. Methods: AsianNeo performed a cross-sectional international questionnaire survey in 2022 to assess the human and physical resources of hospitals and clinical management of very preterm infants. The survey covered various aspects of hospitals resources and clinical management, and data were collected from 337 hospitals across Asia. The data collected were used to compare hospitals resources and clinical management of preterm infants between areas and economic status. Results: The policy of PDA management for preterm infants varied across Asian countries in AsianNeo. Hospitals in Northeast Asia were more likely to perform PDA ligation (p < 0.001) than hospitals in Southeast Asia. Hospitals in Northeast Asia had stricter fluid restrictions in the first 24 h after birth for infants born at <29 weeks gestation (p < 0.001) and on day 14 after birth for infants born at <29 weeks gestation (p < 0.001) compared to hospitals in Southeast Asia. Hospitals in Northeast Asia also had a more humidified environment for infants born between 24 weeks gestation and 25 weeks gestation in the first 72 h after birth (p < 0.001). A logistic regression model predicted that hospitals were more likely to perform PDA ligation for PDA when the hospitals had a stricter fluid planning on day 14 after birth [Odds ratio (OR) of 1.70, p = 0.048], more incubator humidity settings (<80% vs. 80%-89%, OR of 3.35, p = 0.012 and <80% vs. 90%-100%, OR of 5.31, p < 0.001). Conclusions: In advanced economies and Northeast Asia, neonatologists tend to adopt a more conservative approach towards fluid management, maintain higher incubator humidity settings and inclined to perform surgical ligation for PDA.

Colorimetric CO2 Detector to Improve Effective Mask Ventilations in Very Preterm Infants: A Pilot Randomized Controlled Study.

INTRODUCTION: End-tidal CO2 (ETCO2) detector is currently recommended for confirmation of endotracheal tube placement during neonatal resuscitation. Whether it is feasible to use ETCO2 detectors during mask ventilation to reduce risk of bradycardia and desaturations, which are associated with increased risk of death in preterm babies, is unknown. METHODS: This is a pilot randomized controlled trial (NCT04287907) involving newborns 24 + 0/7 to 32 + 0/7 weeks gestation who required mask ventilation at birth. Infants were randomized into groups with or without colorimetric ETCO2 detectors. Combined duration of any bradycardia (<100 bpm) and time below prespecified target oxygen saturation (SpO2) as measured by pulse oximetry were compared. RESULTS: Fifty participants were randomized, 47 with outcomes analysed (2 incomplete data, 1 postnatal diagnosis of trachea-oesophageal fistula). Mean gestational age and birthweight were 28.5 ± 1.9 versus 29.4 ± 1.6 weeks (p = 0.1) and 1,252.7 ± 409.7 g versus 1,334.6 ± 369.1 g (p = 0.5) in the intervention and control arm, respectively. Mean combined duration of bradycardia and desaturation was 276.7 ± 197.7 s (intervention) and 322.7 ± 277.7 s (control) (p = 0.6). Proportion of participants with any bradycardia or desaturation at 5 min were 38.1% (intervention) and 56.5% (control) (p = 0.2). No chest compressions, epinephrine administration, or death occurred in the delivery room. CONCLUSION: This pilot study demonstrates the feasibility of a trial to evaluate colorimetric ETCO2 detectors during mask ventilation of very preterm infants to reduce bradycardia and low SpO2. Further assessment with a larger population will be required to determine if ETCO2 detector usage at resuscitation reduces risk of adverse outcomes, including death and disability, in very preterm infants.

Variations in medical practice of retinopathy of prematurity among 8 Asian countries from an international survey.

Advances in perinatal care have led to the increased survival of preterm infants with subsequent neonatal morbidities, such as retinopathy of prematurity (ROP). This study aims to compare the differences of neonatal healthcare systems, resources, and clinical practice concerning ROP in Asia with review of current literature. An on-line survey at the institutional level was sent to the directors of 336 neonatal intensive care units (NICU) in 8 collaborating national neonatal networks through the Asian Neonatal Network Collaboration (AsianNeo). ROP screening was performed in infants born at < 34 weeks in Indonesia and Japan. In South Korea, Malaysia, and Taiwan, most screened for ROP in infants born at < 32 weeks. In all networks, majority of NICUs conducted ROP screening to infants with birth weight < 1500 g. In most NICU's in-hospital ophthalmologists performed indirect ophthalmoscopy and some were supplemented with digital imaging. Both laser photocoagulation and anti-vascular endothelial growth factor injection are performed for treatment and, vitreous surgeries are conducted less frequently in all countries. Despite limited information collected by the survey, this first study to compare ROP practices implemented in eight Asian countries through AsianNeo will enable an understanding of the differences and facilitate quality improvement by sharing better practices.

Impact of multiple intubation attempts on adverse tracheal intubation associated events in neonates: a report from the NEAR4NEOS.

OBJECTIVE: To determine the relationship between number of attempts and adverse events during neonatal intubation. STUDY DESIGN: A retrospective study of prospectively collected data of intubations in the delivery room and NICU from the National Emergency Airway Registry for Neonates (NEAR4NEOS) in 17 academic centers from 1/2016 to 12/2019. We examined the association between tracheal intubation attempts [1, 2, and ≥3 (multiple attempts)] and clinical adverse outcomes (any tracheal intubation associated events (TIAE), severe TIAE, and severe oxygen desaturation). RESULTS: Of 7708 intubations, 1474 (22%) required ≥3 attempts. Patient, provider, and practice factors were associated with higher TI attempts. Increasing intubation attempts was independently associated with a higher risk for TIAE. The adjusted odds ratio for TIAE and severe oxygen desaturation were significantly higher in TIs with 2 and ≥3 attempts than with one attempt. CONCLUSION: The risk of adverse safety events during intubation increases with the number of intubation attempts.

Supraglottic Airways Compared With Face Masks for Neonatal Resuscitation: A Systematic Review.

BACKGROUND AND OBJECTIVES: Positive pressure ventilation (PPV) is the most important component of neonatal resuscitation, but face mask ventilation can be difficult. Compare supraglottic airway devices (SA) with face masks for term and late preterm infants receiving PPV immediately after birth. METHODS: Data sources include Medline, Embase, Cochrane Databases, Database of Abstracts of Reviews of Effects, and Cumulative Index to Nursing and Allied Health Literature. Study selections include randomized, quasi-randomized, interrupted time series, controlled before-after, and cohort studies with English abstracts. Two authors independently extracted data and assessed risk of bias and certainty of evidence. The primary outcome was failure to improve with positive pressure ventilation. When appropriate, data were pooled using fixed effect models. RESULTS: Meta-analysis of 6 randomized controlled trials (1823 newborn infants) showed that use of an SA decreased the probability of failure to improve with PPV (relative risk 0.24; 95% confidence interval 0.17 to 0.36; P <.001, moderate certainty) and endotracheal intubation (4 randomized controlled trials, 1689 newborn infants) in the delivery room (relative risk 0.34, 95% confidence interval 0.20 to 0.56; P <.001, low certainty). The duration of PPV and time until heart rate >100 beats per minute was shorter with the SA. There was no difference in the use of chest compressions or epinephrine during resuscitation. Certainty of evidence was low or very low for most outcomes. CONCLUSIONS: Among late preterm and term infants who require resuscitation after birth, ventilation may be more effective if delivered by SA rather than face mask and may reduce the need for endotracheal intubation.

Does videolaryngoscopy improve tracheal intubation first attempt success in the NICUs? A report from the NEAR4NEOS.

OBJECTIVE: We hypothesized that videolaryngoscope use for tracheal intubations would differ across NICUs, be associated with higher first attempt success and lower adverse events. STUDY DESIGN: Data from the National Emergency Airway Registry for Neonates (01/2015 to 12/2017) included intubation with direct laryngoscope or videolaryngoscope. Primary outcome was first attempt success. Secondary outcomes were adverse tracheal intubation associated events and severe desaturation. RESULTS: Of 2730 encounters (13 NICUs), 626 (23%) utilized a videolaryngoscope (3% to 64% per site). Videolaryngoscope use was associated with higher first attempt success (p < 0.001), lower adverse tracheal intubation associated events (p < 0.001), but no difference in severe desaturation. After adjustment, videolaryngoscope use was not associated with higher first attempt success (OR:1.18, p = 0.136), but was associated with lower tracheal intubation associated events (OR:0.45, p < 0.001). CONCLUSION: Videolaryngoscope use is variable, not independently associated with higher first attempt success but associated with fewer tracheal intubation associated events.

Risk Factors Predicting the Need for Phototherapy in Glucose 6 Phosphate Dehydrogenase-Deficient Infants in a Large Retrospective Cohort Study.

INTRODUCTION: Glucose 6-phosphate dehydrogenase (G6PD) deficiency increases the risk of severe neonatal hyperbilirubinemia. This study evaluates the risk factors predicting the need for phototherapy in G6PD-deficient neonates after 72 h of age and assesses the safety of early discharge. METHODS: A retrospective cohort study of 681 full-term G6PD-deficient infants with a birth weight ≥2,500 g over 4 years was conducted. We compared the baseline characteristics, bilirubin level on day 4 (after 72 h of life), day of peak bilirubin, G6PD levels, and concomitant ABO incompatibility between the group that required phototherapy (Group A) and those who did not (Group B). RESULTS: 396 infants (58%), predominantly males, required phototherapy in the first week of life. The infants who required phototherapy had a lower median gestational age (38.3 vs. 38.7 weeks, p < 0.01) and had lower G6PD levels (2.3 ± 2.5 vs. 3 ± 3.4 IU, p < 0.05) compared to the controls. The mean day-four total serum bilirubin (TSB) levels were higher (213 ± 32 vs. 151 ± 37 µmol/L, p < 0.01), with bilirubin level peaking earlier (3 vs. 4 days of life, p < 0.01) in group A. Regression analysis identified TSB levels on day 4, Chinese race, lower gestation, and concomitant ABO incompatibility as the significant predictors for the need for phototherapy in the study population. In particular, coexisting ABO blood group incompatibility increased the risk of jaundice requiring phototherapy (OR 4.27, 95% CI: 1.98-121, p < 0.01). Day four TSB values above 180 µmol/L predicted the need for phototherapy with 86% sensitivity and 80% specificity. The findings were similar across both male and female infants with G6PD deficiency. CONCLUSION: G6PD-deficient infants with day four TSB levels of >180 µmol/L (10.5 mg/dL) and associated ABO blood group incompatibility have a higher risk of requiring phototherapy in the first week of life and should be closely monitored.

Perinatal Palliative Care Service: Developing a Comprehensive Care Package for Vulnerable Babies with Life Limiting Fetal Conditions.

Background: Perinatal Palliative Care provides comprehensive and holistic care for expectant and new parents, who receive a diagnosis of life-limiting fetal condition and opt to continue pregnancy and care for their newborn infant. Aim: To develop a service providing individually tailored holistic care during pregnancy, birth, postnatal and bereavement period. Methods: Following a baseline survey of neonatologists and discussions with key stakeholders we launched the Perinatal Palliative service at the KK Women's and Children's hospital, Singapore in January 2017. The multidisciplinary team, led by a Palliative care specialist comprised of Obstetricians, Neonatologists, nurses and medical social workers. The Birth defect clinic referred parents with antenatally diagnosed 'Lethal' fetal conditions. The team checked the understanding and the decision making process of parents and initiated and finalized advance care plans. The service also embraced deserving postnatal referrals upon request. Results: A total of 41 cases were seen from January 2017 to December 2019. Of these, 26/41(63%) were referred antenatally and had completed advance care plans. 18/41 (44%) died during or shortly after birth and 10/41(24%) continue to survive and are supported by the community palliative team. During this time a workflow was formulated and modified based on parent and team feedback. Conclusion: Awareness of the service has increased over the years and a clear workflow has been formulated. Advance care plans are prepared and documented before birth so as to enable service teams on board to provide well timed pertinent care. Feedbacks from parents about this service were positive.

Guidance for the clinical management of infants born to mothers with suspected/confirmed COVID-19 in Singapore.

In this paper, we provide guidance to clinicians who care for infants born to mothers with suspected/confirmed COVID-19 during this current pandemic. We reviewed available literature and international guidelines based on the following themes: delivery room management; infection control and prevention strategies; neonatal severe acute respiratory syndrome coronavirus 2 testing; breastfeeding and breastmilk feeding; rooming-in of mother-infant; respiratory support precautions; visiting procedures; de-isolation and discharge of infant; outpatient clinic attendance; transport of infant; and training of healthcare staff. This guidance for clinical care was proposed and contextualised for the local setting via consensus by members of this workgroup and was based on evidence available as of 31 July 2020, and may change as new evidence emerges.

Moisturisers from birth in at-risk infants of atopic dermatitis - a pragmatic randomised controlled trial.

BACKGROUND: Atopic dermatitis (AD) is a common, chronic dermatosis, with onset of disease often manifesting in early infancy. Past studies evaluating the early use of moisturisers in the prevention of AD had mixed results. OBJECTIVES: To compare the incidence of moderate or severe AD and total incidence of AD in a cohort of 'at-risk' infants treated with moisturisers from the first 2 weeks of life, to a similar group without moisturisers. METHODS: We performed a single-centre, prospective, parallel-group, randomised study in infants with at least 2 first-degree relatives with atopy. Subjects were randomised into either a treatment group with moisturisers or a control group without moisturisers. Participants were assessed at 2, 6, and 12 months for AD and if present, the severity was assessed using SCORAD index. We also compared the overall incidence of AD, trans-epidermal water loss (TEWL), stratum corneum (SC) hydration, pH, and incidence of food and environmental sensitisation and allergies between both groups. Genotyping for loss-of-functions mutations in the FLG gene was conducted. RESULTS: A total of 200 subjects were recruited, with 100 subjects in each arm. There was no significant difference in incidence of moderate or severe AD, and total incidence of AD at 12 months between the treatment and control groups. There was a lower mean SCORAD in the treatment group than in the control group, but no significant difference in TEWL, SC hydration, and skin pH. No significant side-effects were reported. CONCLUSIONS: The early use of moisturisers in 'at-risk' infants does not reduce the incidence of moderate-to-severe AD and overall incidence of AD in infancy.

A narrative review of Poland's syndrome: theories of its genesis, evolution and its diagnosis and treatment.

Poland's syndrome (PS) is a rare musculoskeletal congenital anomaly with a wide spectrum of presentations. It is typically characterized by hypoplasia or aplasia of pectoral muscles, mammary hypoplasia and variably associated ipsilateral limb anomalies. Limb defects can vary in severity, ranging from syndactyly to phocomelia. Most cases are sporadic but familial cases with intrafamilial variability have been reported. Several theories have been proposed regarding the genesis of PS. Vascular disruption theory, "the subclavian artery supply disruption sequence" (SASDS) remains the most accepted pathogenic mechanism. Clinical presentations can vary in severity from syndactyly to phocomelia in the limbs and in the thorax, rib defects to severe chest wall anomalies with impaired lung function. Most patients have subtle presentation at birth and milder forms in childhood. Functional limitations due to PS are usually minimal. Surgical treatment aims to improve pulmonary functions arising from severe thoracic deformities but is more often done to enhance the cosmesis. The use of adipose-derived mesenchymal stem cells and fat transfer have shown promising results in recent times for correction of chest defects and breast augmentation. Gaining deeper insights into the etiopathogenesis and clinical presentation of PS will improve the clinical recognition and management of this rare condition. In this review article, we aim to outline the details of this syndrome including its etiopathogenesis, evolution, spectrum of clinical manifestations, other systemic associations, diagnostic modalities, and recent advances in treatment.

Associations of Stylet Use during Neonatal Intubation with Intubation Success, Adverse Events, and Severe Desaturation: A Report from NEAR4NEOS.

INTRODUCTION: Intubations are frequently performed procedures in neonatal intensive care units (NICU) and delivery rooms (DR). Unsuccessful first attempts are common as are tracheal intubation-associated events (TIAEs) and severe desaturations. Stylets are often used during intubation, but their association with intubation outcomes is unclear. OBJECTIVE: To compare intubation success, rate of relevant TIAEs, and severe desaturations in neonates intubated with and without stylets. METHODS: Tracheal intubations of neonates in the NICU or DR from 16 centers between October 2014 and December 2018, performed by neonatology or pediatric providers, were collected from the NEAR4NEOs international registry. Primary oral intubations with a laryngoscope were included in the analysis. First-attempt success, the occurrence of relevant TIAEs, and severe oxygen desaturation (≥20% saturation drop from baseline) were compared between intubations performed with versus without a stylet. Logistic regression with generalized estimate equations was used to control for covariates and clustering by sites. RESULTS: Out of 5,292 primary oral intubations, 3,877 (73%) utilized stylets. Stylet use varied considerably across the centers with a range between 0.5 and 100%. Stylet use was not associated with first-attempt intubation success, esophageal intubation, mainstem intubation, or severe desaturations after controlling for confounders. Patient size was associated with these outcomes and much more predictive of success. CONCLUSIONS: Stylet use during neonatal intubation was not associated with higher first-attempt intubation success, fewer relevant TIAEs, or less severe desaturations. These data suggest that stylets can be used based on individual preference, but stylet use may not be associated with better intubation outcomes.

Academic school readiness in children born very preterm and associated risk factors.

BACKGROUND AND AIMS: Although the intelligence quotient (IQ) test is useful to assess general cognitive function, it may miss more specific and subtle deficits of learning, working memory, attention and executive function. This study aims to evaluate cognitive performance and academic school readiness (SR) concepts in preterm very low birth weight (PT/VLBW) children, compared to typically developing term controls and to evaluate factors affecting basic (SR) concepts in children with IQ>85. METHODS: A prospective cohort study of 123 PT/VLBW survivors with birth weights ≤1250 g and 74 term controls born between 2007 and 2009 in Singapore were assessed for school readiness using Wechsler Preschool and Primary Scale of Intelligence (WPPSI-III), Bracken School Readiness Assessment (BSRA-3) and Beery-Buktenica Developmental Test of Visual Motor Integration (VMI) at age 5.5 years. Social risk composite score (SRCS) was calculated based on ethnicity, parental education and family income and marital status. Uni- and multi-variable regressions were conducted to evaluate risk factors associated with poor academic SR in the entire cohort and in those with IQ >85. RESULTS: Mean gestational age and birth weight of the 123 PT/VLBW children were 27.8 (2.3) weeks and 939 (194) grams while that of the 74 term controls were 38.8 (1.2) weeks and 3165 (402) grams. PT/VLBW survivors had statistically significant lower full composite scores on WPPSI-III (97.0 vs 114), BSRA-3 (98.5 vs 112.3) and VMI (107.2 vs 112.9) compared to controls. The differences remained significant in preterm and children with higher SRCS even after adjustment. CONCLUSIONS: Prematurity and high social composite risk scores were risk factors affecting academic SR and this difference persisted in PT/VLBW children with normal cognitive scores with IQ >85.

Singapore Neonatal Resuscitation Guidelines 2021.

Neonatal resuscitation is a coordinated, team-based series of timed sequential steps that focuses on a transitional physiology to improve perinatal and neonatal outcomes. The practice of neonatal resuscitation has evolved over time and continues to be shaped by emerging evidence as well as key opinions. We present the revised Neonatal Resuscitation Guidelines for Singapore 2021. The recommendations from the International Liaison Committee on Resuscitation Neonatal Task Force Consensus on Science and Treatment Recommendations (2020) and guidelines from the American Heart Association and European Resuscitation Council were compared with existing guidelines. The recommendations of the Neonatal Subgroup of the Singapore Resuscitation and First Aid Council were derived after the work group discussed and appraised the current available evidence and their applicability to local clinical practice.

Effectiveness of Palivizumab Against Respiratory Syncytial Virus Hospitalization Among Preterm Infants in a Setting With Year-Round Circulation.

BACKGROUND: The year-round respiratory syncytial virus (RSV) circulation in tropical regions leads to different transmission patterns and burden of disease among infants born very preterm. METHODS: We conducted a retrospective cohort study to estimate the effectiveness of palivizumab in preventing RSV hospitalization at 6 and 12 months after discharge, among infants born at <32 weeks' gestation in our tropical setting. RESULTS: A total of 109 infants (26.3%) received palivizumab at discharge, of 415 who were eligible. All patients received ≥4 doses, with 105 infants (96.3%) completing 5 doses. Within 1 year after discharge, there were 35 RSV-associated admissions (3 [2.8%] in the palivizumab vs 32 [10.5%] in the nonpalivizumab group; P = .02). After adjustment for confounders, the effectiveness of palivizumab against RSV hospitalization was estimated to be 90% (95% confidence interval, 10%-99%) up to 6 months after discharge. The median time to RSV hospitalization was shorter in the nonpalivizumab than in the palivizumab group (median [range], 155 [15-358] vs 287 [145-359] days, respectively; P = .11). Five infants (14.3%), all from the nonpalivizumab group, required admission to the intensive care unit. CONCLUSIONS: In our setting with year-round RSV circulation, palivizumab prophylaxis was effective in reducing RSV hospitalization among high-risk preterm infants of <32 weeks' gestation within the initial 6 months after discharge.

Successful containment of horizontal enterovirus infection in a neonatal unit in Singapore through diagnosis by polymerase chain reaction (PCR) and direct sequence analysis.

BACKGROUND: Enterovirus (EV) outbreaks often coincide with seasonal peaks in the community. However, they may also sporadically occur in neonatal units. Identification of EV infection in neonates can be challenging, as they tend to present with mild or nonspecific symptoms. This study reports an EV outbreak in the Neonatal Unit at KK Women's and Children's Hospital, Singapore. METHODS: This is a single-center, retrospective cohort study of neonates who had positive results for EV during the outbreak. Demographic characteristics, clinical presentations and outcomes were analyzed. Control measures used to limit the spread of infection are reported. RESULTS: A total of 7 cases of EV infection were identified. Their median birth weight and gestational age were 1240 g (750 -2890 g) and 28 weeks (26-35 weeks), respectively. Symptoms occurred at a median age of 48 days (9-103 days). All cases presented initially with recurrent apnea and 4 needed assisted ventilator support with CPAP (2) and mechanical ventilation (2). Serious complications occurred in 3 infants (2 with necrotizing enterocolitis and 1 with meningitis) and none died. EV was detected from rectal swabs (n = 6), CSF (n = 2) and nasopharyngeal swabs (n = 2). Viral subtyping uniformly revealed echovirus 25. Surveillance of all exposed infants by nasopharyngeal swabs was implemented, along with strict contact precautions and cohorting measures. CONCLUSIONS: Premature infants with EV are more prone to serious complications, which can lead to significant morbidity. Thus, early recognition of symptoms, rapid diagnosis and prompt implementation of infection control measures are key to prevent further spread of infection.
