RESUMEN

BACKGROUND: Premedication in neonates undergoing elective intubation effectively minimizes the negative physiological events of bradycardia, systemic hypertension, intracranial hypertension, and hypoxia. Premedication decreases procedure-related pain and discomfort. This study aimed to evaluate the current practice of pre-intubation medications for non-emergent intubations in preterm and term neonates in the United States. STUDY DESIGN: A cross-sectional survey (Appendix) was sent via e-mail to all level 3 and 4 Neonatal Intensive Care Units (NICUs) of the Organization of Neonatal Perinatal Medicine Training Program Directors (ONTPD), NICU directors with pediatric residency only, and Baylor Scott and White Health, Mednax, and Envision health services systems. RESULTS: Of 170 responses, 41% (69/168) routinely premedicate, 38% (64/168) premedicate under specific circumstances, and 21% (35/168) do not administer any routine pre-intubation medications. Only 46% (77/168) of units had a written policy. The most frequently used drugs were fentanyl (68%, 116/170), atropine (39%, 66/170), midazolam (38%, 64/170), and morphine (26%, 45/170). 21% (36/170) used a two-drug combination, and 38% (64/170) used a three-drug combination. The most commonly used two-drug combination was atropine and fentanyl, and the most common three-drug combination was atropine, fentanyl, and a paralytic agent. CONCLUSION:  Despite the well-documented benefits of premedication for NICU intubations, as aligned with AAP recommendations, the US lags behind other nations, with stagnant rates since 2006. This disparity persists despite a rise in written policies, which exhibit significant content variations. The authors advocate for the adoption of standardized, AAP-aligned policies across all NICUs in the US. Continued research is vital to monitor the progress of this crucial practice and address any underlying barriers to implementation.

RESUMEN

Background This study evaluates the long-term risk of autism spectrum disorder (ASD) in infants with intraventricular hemorrhage (IVH) using the Modified Checklist for Autism in Toddlers-Revised with Follow-Up (M-CHAT-R/F) screening tool. Methods This retrospective cohort study compared IVH (exposed) infants across all gestational age groups with no-IVH (non-exposed) infants admitted to level IV neonatal intensive care unit (NICU). The M-CHAT-R/F screening tool was used to assess the ASD risk at 16-30 months of age. Discharge cranial ultrasound (CUS) findings also determined the ASD risk. Descriptive statistics comprised median and interquartile range for skewed continuous data and frequencies and percentages for categorical variables. Comparisons for non-ordinal categorical measures in bivariate analysis were carried out using the χ2 test or Fisher exact test. Results Of the 334 infants, 167 had IVH, and 167 had no IVH. High ASD risk (43% vs. 20%, p = 0.044) and cerebral palsy (19% vs. 5%, p = 0.004) were significantly associated with severe IVH. Infants with CUS findings of periventricular leukomalacia had 3.24 odds of developing high ASD risk (odds ratios/OR: 3.24, 95% confidence interval/CI: 0.73-14.34), and those with hydrocephalus needing ventriculoperitoneal (VP) shunt had 4.75 odds of developing high ASD risk (OR: 4.75, 95% CI: 0.73-30.69). Conclusion Severe IVH, but not mild IVH, increased the risk of ASD and cerebral palsy. This study demonstrates the need for timely screening for ASD in high-risk infants. Prompt detection leads to earlier treatment and better outcomes.

RESUMEN

Background: Preeclampsia (PreE), the de novo onset of hypertension and proteinuria at 20 weeks of gestation, is a leading cause of maternal and fetal morbidity and mortality. This study compared inflammatory biomarkers in PreE and normal pregnancies using paired samples of mothers and neonates. Methods: Twenty normal pregnant and 27 PreE patients were monitored for biomarkers, neonatal outcomes, and placental morphologies. Fetal and maternal serum levels of vascular endothelial growth factor (VEGF), placental growth factor (PlGF), soluble endoglin (sENG), and soluble fms-like tyrosine kinase-1 (sFLT-1) were measured by enzyme-linked immunosorbent assay. Results: Placental thickness was 25 mm in early PreE subjects compared to 32 mm in late PreE subjects (P < 0.05). Placental volume was 296 cm3 in early PreE compared to 393 cm3 in late PreE (P < 0.05). The average hospital stay for PreE babies was longer (20 ± 5 days) compared to babies from normal pregnancies (2 ± 1 days; P < 0.05). PreE babies had a lower Ponderal index (2.28 ± 0.3) than those from normal pregnancies (2.95 ± 0.2; P < 0.05). sENG and sFLT-1 had cord values like the maternal values, while VEGF and PlGF did not. Conclusion: PreE alters the intrauterine environment by activating chemical mediators that result in maternal and fetal complications.

RESUMEN

Gastroschisis is a common type of congenital anterior abdominal wall defect with intraabdominal organs exposed outside the abdominal cavity. With modern neonatology and surgical practices, the overall prognosis for infants with gastroschisis is excellent. However, a subset of infants with gastroschisis will develop complications, requiring repeat surgical interventions. We present a case of a female infant with complicated gastroschisis who developed acute perforated acalculous cholecystitis, which was accurately diagnosed with abdominal ultrasound and successfully treated with medical management and a percutaneous cholecystostomy tube.

RESUMEN

BACKGROUND: Human milk, the ultimate source of nutrition for premature infants, enhances host defense mechanism, gastrointestinal maturation, lowers infection rate, improves neurodevelopmental outcomes, and reduces long-term cardiovascular and metabolic disease. Recently, there has been an increase in donor breast milk (DBM) use for premature infants; however, data are limited on the long-term effects of DBM on the infant's growth and neurodevelopmental outcomes. OBJECTIVE: To determine if there is an association between type of infant nutrition (maternal breast milk (MBM) or DBM) and neurodevelopmental and growth outcomes in very low birth weight (VLBW) infants. DESIGN/METHODS: Retrospective cohort study of VLBW (<1500 g) infants admitted to the Baylor Scott & White Memorial Hospital Neonatal Intensive Care Unit from January 2014 to December 2016. Infants with major congenital anomalies, born at an outside hospital, who were nil per os (NPO) for >15 days, or who died before NICU discharge were excluded. Infants were stratified into two groups (MBM or DBM) based on predominant nutrition (>50%) received in the first month of life. Primary outcomes of neurodevelopmental delay(s) between 2 and 4 years of age identified via ICD 9/10 codes. Growth data (weight, length, and head circumference) were obtained from well-check visits at 12-, 18-, 24-, 36-, and 48-months. Severity of illness was determined using the Clinical Risk Index in Babies-II (CRIB-II) score. Generalized linear models were used to assess the relationship between nutrition and neurodevelopmental delay and trends in growth over time. RESULTS: Two hundred and nine infants were included: 146 MBM; 63 DBM. Median gestational age was 28 weeks (range, 23-35) and median birthweight was 1050 g (range, 410-1470). There were no significant differences in birthweight, gestational age, CRIB-II score, or length of stay between the groups. Infants fed DBM had a significantly larger weight z-score (p=.005), length z-score (p=.01), and head circumference z-score (p=.04), on average from birth to 48 months compared to MBM infants, while controlling for NICU length of stay and number of follow-up months; however, this only equated to DBM infants being 0.5 in taller and 0.9 lbs heavier at 48 months. There were no statistically significant differences among type of infant nutrition and long-term neurodevelopmental outcomes, while controlling for CRIB-II score. CONCLUSIONS: Infants fed DBM have a slightly greater propensity for growth over time compared to infants fed MBM. Longer follow-up is needed to further determine the effect, infant nutrition has on neurodevelopmental outcomes.

Comprehensive metabolic panel is significant for hyponatremia, with a sodium level of 132 mEq/L (132 mmol/L; reference range, 135-145 mEq/L [135-145 mmol/L]). Liver enzyme levels are normal (alanine aminotransferase, 41 U/L [0.68 µkat/L]; aspartate aminotransferase, 86 U/L [1.44 µkat/L]), as are total protein (5.4 g/dL [54 g/L]) and albumin (3.0 g/dL [30 g/L]) levels. Repeated bilirubin level is 12.4 mg/dL (212 µmol/L) at 14 hours after birth, with an elevated direct bilirubin level of 2.9 mg/dL (49.6 µmol/L). Direct or conjugated hyperbilirubinemia is defined as a direct bilirubin level greater than 2 mg/dL (34.2 mmol/L) or more than 20% of total bilirubin. γ-Glutamyl transferase level is normal. Coagulation studies show an elevated prothrombin time of 23.4 seconds (reference range, 11-17 seconds), with an international normalized ratio of 2.1 (reference range, 0.9-1.3); activated partial thromboplastin level is 49.5 seconds (reference range, 30-60 seconds). Fibrinogen level is decreased at 70 mg/dL (0.70 g/L) (reference range, 230-450 mg/dL [230-450 g/L]). Lactate level is 24.3 mg/dL (2.7 mmol/L; reference range, 2.0-26.9 mg/dL [0.22-2.98 mmol/L]). Ammonia level is 96.6 µg/dL (69 µmol/L; reference range, 89.6-149.9 µg/dL [64-107 µmol/L]). Cerebrospinal fluid studies are unremarkable. Magnetic resonance imaging (MRI) of the brain and echocardiography are normal. Ultrasonography of the abdomen shows diffuse hepatic echogenicity. Blood and cerebrospinal fluid cultures are negative. Further testing reveals the diagnosis.

RESUMEN

OBJECTIVE: Since the first publication of the American College of Obstetricians and Gynecologists committee opinion in 2012, and following the update in 2017, multiple institutions in the United States (US) adopted the practice of delayed cord clamping (DCC) and/or umbilical cord milking (UCM) in preterm and term infants. However, there have been variations reported in practices with regard to method of placental transfusion, timing of cord clamping and gestational age thresholds. Furthermore, the optimal cord clamping practice in situations of depressed infants needing resuscitation or in higher-risk delivery situations, such as placental abruption, intrauterine growth restriction, multiple gestation, chorioamnionitis, maternal human immunodeficiency virus syndrome/hepatitis or maternal general anesthesia is often debated. An evaluation of these variations and exploration of associated factors was needed to optimally target opportunities for improvement and streamline research activities. The objective of this survey, specifically aimed at neonatologists working in the US was to identify and describe current cord clamping practices and evaluate factors associated with variations. STUDY DESIGN: The survey was distributed electronically to the US neonatologists in August 2019 with a reminder email sent in October 2019. Clinicians were primarily identified from Perinatal Section of AAP, with reminders also sent through various organizations including California Association of Neonatologists, Pediatrix and Envision national groups. Descriptive variables of interest included years of experience practicing neonatology, affiliation with a teaching institution, level of the neonatal intensive care unit (NICU) and practicing region of the US. Questions on variations in cord management practices included information about center specific guideline/protocol, cord clamping practices, gestational age threshold of placental transfusion, performance of UCM and practice in higher-risk delivery situations. RESULTS: The response rate was 14.8%. Among 517 neonatologists whom responded, majority (85.5%) of the practices had a guideline and performed (81.7%) DCC in all gestational ages. The cord clamping practice was predominantly DCC and it was categorized as reporting clamping times <60 s in 46.6% and ≥60 s in 48.7% of responses. A significant association was detected between time of delay in cord clamping and region of practice. The Northeast region was more likely to clamp the cord in <60 s than other regions in the US. More than half of the providers responded not performing any UCM (57.3%) in their practice. Significant associations were detected between performance of UCM and all queried demographic variables independently. Clinicians with >20 years of experience were more likely from institutions performing UCM compared to the providers with fewer years of experience. However, teaching hospitals were less likely to perform UCM compared to non-teaching hospitals. Similarly, practices with level IV NICUs were less likely to perform UCM compared to practices with level III units. Hospitals in the Midwest region of US were less likely to perform UCM compared to hospitals in the Western region. Significant variations were also noticed for not providing placental transfusion in higher-risk deliveries. Demographic and professional factors were noted to be associated with these differences. CONCLUSION: Although the majority of practices have a guideline/protocol and are performing DCC in all gestational ages, there are variations noted with regard to timing, method, and performance in higher-risk deliveries. Demographic and professional factors play an important role in these variations. Future research needs to focus on the modifiable factors to optimize the procedure and impact of DCC.

RESUMEN

OBJECTIVE: This article aims to determine the incidence of short-term complications of surgical patent ductus arteriosus (PDA) ligations, the factors associated with those complications, and whether complications are associated with poor long-term outcomes. STUDY DESIGN: Retrospective cohort study of all extremely low birth weight (ELBW, < 1,000 g) infants who underwent surgical PDA ligation at a single-center neonatal intensive care unit from 1989 to 2015. Demographic, clinical, and laboratory data were reviewed. The primary outcome was development of a short-term (< 2 weeks from ligation) surgical complication. Secondary outcomes include bronchopulmonary dysplasia (BPD), length of stay, and mortality. RESULTS: A total of 180 ELBW infants were included; median gestational age and birth weight was 24 weeks and 683 g, respectively, and 44% of infants had at least one short-term complication. Need for vasopressors (33%) was the most common medical complication and vocal cord paralysis (9%) was the most common surgical complication. Younger corrected gestational age at time of repair was associated with increased risk for complications. Mortality, length of stay, and BPD rates were similar between infants with and without complications. CONCLUSION: Serious complications were seen in a minority of infants. Additional research is needed to determine if short-term complications are associated with long-term adverse outcomes.

RESUMEN

OBJECTIVES: To ascertain parental perceptions of the impact of restricted visiting policies to neonatal intensive care units during the current COVID-19 pandemic. DESIGN: Cross-sectional survey of parents impacted by visitation policies. SETTING: Six tertiary level neonatal units, four from the UK and two from the USA, participated in the study. PARTICIPANTS: Parents and families of infants hospitalised in the participating centres between 1 May 2020 and 21 August 2020. METHODS: Online-based and/or paper-based survey, querying the visitation policies and their impact on parents' ability to visit, care for and bond with their infants. RESULTS: A total of 231 responses were received. Visitation limited to a single visitor with no restrictions on duration was the most frequently reported policy; 140/217 (63%). Visitation policies were perceived as being restrictive by 62% (138/219) of the respondents with 37% (80/216) reporting being able to visit less often than desired, 41% (78/191) reporting being unable to bond enough and 27% (51/191) reporting not being able to participate in their baby's daily care. Mild to severe impact on breast feeding was reported by 36% (75/209) of respondents. Stricter policies had a higher impact on families and were significantly associated with a lack of bonding time, inability to participate in care and an adverse impact on breast feeding. CONCLUSIONS: Visitation policies during the COVID-19 pandemic varied between centres and over time with stricter restrictions implemented earlier on in the pandemic. Parents reported significant impacts on their ability to visit, care for and bond with their infants with perceived severity of impact worse with stricter restrictions.

RESUMEN

The interaction between pre-eclampsia and diabetes mellitus (DM) is far from being completely understood. In this study, we compared normal pregnancies with those complicated with pre-eclampsia, gestational DM, and/or pre-existing diabetes to assess the effects of hyperglycemia on placental development. AnInstitutional Review Board (IRB) approved retrospective cross-sectional study with 621 subjects was performed. Statistical analysis was performed using Duncan's post hoc test and analysis of variance. Regardless of diabetes status, patients with pre-eclampsia delivered prematurely. Patients in the group with pre-eclampsia and pregestational diabetes delivered much earlier, at 35.0±0.4 weeks, when compared with the patients that had pre-eclampsia with gestational diabetes and pre-eclampsia with no diabetes (*P<0.05 for each). Additionally, patients with pre-existing diabetes who developed pre-eclampsia delivered smaller babies than those with pre-existing diabetes without pre-eclampsia (1.00±0.03, P<0.05 for each). Pre-existing diabetes with added insult of pre-eclampsia led to fetal growth restriction. This outcome validates the understanding that elevated glucose earlier in pregnancy alters placentogenesis and leads to fetal growth restriction.

RESUMEN

Background Normal pregnancy relies on a careful balance between immune tolerance and suppression. It is known that strict regulation of maternal immune function, in addition to components of inflammation, is paramount to successful pregnancy, and any imbalance between proinflammatory and anti-inflammatory cytokines and chemokines can lead to aberrant inflammation, often seen in complicated pregnancies. Inflammation in complicated pregnancies is directly associated with increased mortality and morbidity of the mother and offspring. Aberrant inflammatory reactions in complicated pregnancies often lead to adverse outcomes, such as spontaneous abortion, preterm labor, intrauterine growth restriction, and fetal demise. The role of inflammation in different stages of normal pregnancy is reviewed, compared, and contrasted with aberrant inflammation in complicated pregnancies. The complications addressed are preterm labor, pregnancy loss, infection, preeclampsia, maternal obesity, gestational diabetes mellitus, autoimmune diseases, and inflammatory bowel disease. Aim This article examines the role of various inflammatory factors contributing to aberrant inflammation in complicated pregnancies. By understanding the aberrant inflammatory process in complicated pregnancies, novel diagnostic tools and therapeutic interventions for modulating it appropriately can be identified.

RESUMEN

This double-blinded, randomized, crossover study evaluated the safety and effectiveness of 20 mL/kg aliquots of packed red blood cell (PRBC) transfusions versus 15 mL/kg aliquot transfusions in very low birth weight (VLBW) infants with anemia. The study enrolled 22 hemodynamically stable VLBW infants requiring PRBC transfusions, with a mean gestational age of 25.7 ± 2.2 weeks and birth weight of 804 ± 261 g. Each infant was randomized to receive one of two treatment sequences: 15 mL/kg followed by 20 mL/kg or 20 mL/kg followed by 15 mL/kg. The infants were monitored during and after transfusions, and the efficacy and safety of the treatments were evaluated. Infants had higher posttransfusion hemoglobin (13.2 g/dL vs 11.8 g/dL, P < 0.01) and hematocrit levels (38.6 g/dL vs 34.4 g/dL, P < 0.01) following 20 mL/kg PRBC transfusions when compared to 15 mL/kg transfusions. There were no differences in the incidence of tachypnea, hepatomegaly, edema, hypoxia, necrotizing enterocolitis, or vital sign instability between groups. In conclusion, high-volume PRBC transfusions (20 mL/kg) were associated with higher posttransfusion hemoglobin and hematocrit levels but no adverse effects. Higher-volume transfusions may reduce the need for multiple transfusions and therefore the number of donors the infant is exposed to.

RESUMEN

Introduction Preeclampsia (preE) is pregnancy-induced hypertension affecting a significant proportion of pregnant women worldwide and can cause detrimental effects in the mother and newborn. Some of the effects in the newborn include neonatal thrombocytopenia. Pertaining specifically to neonatal thrombocytopenia, several questions remain unanswered. Discussion According to the current literature, neonatal thrombocytopenia due to maternal preE is highly prevalent in the general population and the incidence is reported to be around 30% worldwide. This review gives an insight into the syndrome and summarizes the possible pathological mechanisms, the diagnostic approach, complications, and therapeutic interventions of neonatal thrombocytopenia. It also identifies the involvement of other cell lines, apart from platelets in the newborns. Furthermore, we suggest a future prospective study to investigate the pathogenesis of preE and plan a study involving animal models to come up with a possible therapeutic intervention to prevent preE and its various consequences in neonates.

RESUMEN

To understand factors contributing to the neonatal mortality rate (NMR), we studied trends in the NMR during 2000 to 2009 with respect to demographic factors and health care resources. Birth- and death-linked mortality data for 14,168 neonatal deaths that occurred between 2000 and 2009 were obtained from the Texas Department of Health and Human Services. Demographic factors and health care resource data were analyzed using analysis of variance, chi-square tests, and linear regression analysis. The average NMR increased from 3.37 in 2000 to 3.77 in 2009. The NMR in blacks ranged from 6.57 to 8.97 during the study period. Among the babies who died, the mean birthweight decreased from 1505 to 1275 g (P < 0.001) and the mean gestational age decreased from 28.4 to 27.8 weeks (P < 0.001). Cesarean section deliveries increased from 32.7% to 44.9% (P < 0.001). The percentage of mothers receiving prenatal care increased from 81.4% to 86.6% (P < 0.001). Mothers with a college education increased from 8.8% to 20.5% (P < 0.001). The median household income increased from $41,047 to $49,189 (P < 0.001). The number of neonatal intensive care unit beds increased from 33.4 to 56 per 10,000 births, and the number of neonatologists increased from 0.27 to 0.40 per 10,000 women of 15 to 44 years of age. In conclusion, the NMR didn't improve despite improvements in demographic factors and health care resources. Racial disparities persist, with a high NMR in the black population. We speculate a possible genetic predisposition related to ethnicity, and a potentially higher rate of extreme prematurity might have contributed to a high NMR in the study population.

RESUMEN

OBJECTIVE: To evaluate reliability of umbilical cord blood (UCB) for complete blood count (CBC) and blood cultures compared with the infant's blood from peripheral site for group B streptococcal (GBS) sepsis screening. METHODS: A total of 200 neonates, at risk for GBS infection, were studied prospectively. After birth, UCB sample was obtained for CBC and blood cultures from umbilical vein. Peripheral arterial/venous blood was obtained from the neonate. RESULTS: In 200 neonates, CBC counts were similar for clinical significance except for leukopenia (6% in UCB vs 1.2% in peripheral blood, P = .02). One UCB sample grew GBS and another grew microaerophilic streptococcus, a contaminant. A neonatal sample grew Escherichia coli, a pathogen and another neonatal sample grew Staphylococcus auricularis, a contaminant. CONCLUSION: CBC results were similar from UCB and the infant for the purpose of GBS screening. Contamination of UCB sample for culture is uncommon. Hence, UCB may be used for GBS sepsis screen.
