Exchange transfusion for neonatal hyperbilirubinemia: A multicenter, prospective study of Turkish Neonatal Society.

Objective: The frequency of neonatal exchange transfusion has declined in recent years, but is still performed in many countries. The procedure is associated with complications. The aim of the study was to determine the clinical features and etiologies of infants with hyperbilirubinemia who underwent exchange transfusion and evaluate the adverse events and clinical outcomes. Material and Methods: We performed a secondary analysis of the multicenter Turkish Neonatal Jaundice Online Registry data. Otherwise healthy newborns born ≥35 weeks of gestation who were hospitalized for jaundice and underwent exchange transfusion were included. Results: One-hundred thirty-two patients with a mean serum bilirubin level on admission of 24.9±9.1 mg/dL were enrolled in the study. The most common cause for exchange transfusion was hemolytic jaundice (63.6%), followed by lack of proper feeding (12.9%). It was found that the infants with lack of proper feeding were discharged earlier from the maternity ward (p=0.02), but they were admitted to hospital later (p<0.001) with a higher bilirubin level (p=0.001), and geater weight loss (p=0.04). The reported rate of adverse events associated with exchange transfusion was 11.4%. The most common complication was thrombocytopenia (40%). None of the infants died during the procedure. Acute bilirubin encephalopathy was reported in 13 (9.8%) patients. Conclusion: Severe hyperbilirubinemia requiring exchange transfusion and acute bilirubin encephalopathy are still challenging problems in neonatal periodin our country. The policies including blood group analysis of pregnant women, programs informing parents about breastfeeding and jaundice, and monitoring bilirubin levels of high-risk newborns should be developed to reduce the necessitating for exchange transfusion and to avoid related complications.

Eating Behaviors of Late and Moderately Preterm Infants at Two Years of Age and Their Associations With Mothers' Mental Health.

OBJECTIVES: Preterm infants are at high risk for nutritional difficulties during the neonatal period and early childhood. Long-term nutritional difficulties contribute to unbalanced food intake and growth disorders and are the source of major emotional stress for the family. The aim of this study is to investigate the eating problems of late and moderately preterm (LMPT) infants at the age of 2 years, and to examine the association of these problems with the mental status of their mothers. METHODS: In this cross-sectional study, group 1 included LMPT infants born between 32 and 36 + 6 weeks of gestation and Group 2 included term infants born between 37 and 41 + 6 weeks of gestation. Children's Nutrition Difficulties Questionnaire and 21-item Depression Anxiety and Stress Scales (DASS 21) were used for the detection of nutritional difficulties of infants and mothers' mental health status. RESULTS: Groups 1 and 2 were consisted of 79 LMPT and 38 term infants, respectively. Late and moderately preterm infants were found to have a lower drive-to-eat and food repertoire scores as well as lower appetite and food enjoyment than term infants. Pickiness and food neophobia were found to be higher in LMPT infants than term infants. The DASS-21 scores of the mothers of the LMPT infants were higher than those of the term ones. CONCLUSIONS: These findings suggest that LMPT infants have more nutritional difficulties at the age of 2 years than term infants and their mothers exhibit more emotional distress than term infant's mothers.

The effects of noise reduction by earmuffs on the physiologic and behavioral responses in very low birth weight preterm infants.

OBJECTIVE: Preterm infants are exposed to loud noises during their stay in the neonatal intensive care unit which can lead to physiologic and behavioral alterations and even hearing loss. The use of earmuffs can reduce sound level and these changes. The objective of the present study is to evaluate the effectiveness of the earmuffs in preterm infants solely cared for in closed incubators. METHODS: A comparative prospective study comprising 20 clinically stable preterm infants weighing less than 1500 g cared in closed incubator was conducted. Preterm infants acted as their own controls whereby they were observed without earmuffs (Group 1) for 2 days and with earmuffs (Group 2) on consecutive 2 days. The preterm infants' physiologic responses and Anderson Behavioral State Scoring System (ABSS) scores were assessed over 30s every 2h for 8h during daytime for 4 days. RESULTS: Out of 20 preterm infants, 6 were male and 14 female with a mean birth weight of 1220 ± 209 g, gestational age of 29.9 ± 2.1 weeks. The total number of measurements was 320. The mean ABSS scores of Group 1 and 2 were 3.07±1.1 and 1.34 ± 0.3, respectively. Statistically significant difference was noted between the means of ABSS scores (p<0.001). Preterm infants with earmuffs (87.5%) were more frequently observed in a quiet sleep state of ABSS compared with those without earmuffs (29.4%). CONCLUSIONS: Noise level reduction was associated with significant improvement in behavioral states of ABSS. We suggest that noise reduction in preterm infants with earmuffs is helpful by improving sleep efficiency and increasing time of quiet sleep.

Effect of neonatal resuscitation courses on long-term neurodevelopmental outcomes of newborn infants with perinatal asphyxia.

BACKGROUND: In previous studies, it has been demonstrated that Neonatal Resuscitation Program (NRP) courses improve the early outcomes of infants with perinatal asphyxia, but there has been no evidence to demonstrate the effect of NRP on long-term outcomes of perinatal asphyxia. The goal of the present study was to determine the effect of NRP courses on the long-term neurodevelopmental outcome of perinatal asphyxia. METHODS: This prospective study included infants referred to the Neonatal Unit during the years 2003-2005. Those patients who were referred before NRP courses (pretraining period) were designated as group 1, those who were referred after the first NRP course (transition period) as group 2, and those who were referred after the second NRP course (post-training period) as group 3. Neurodevelopmental outcomes were assessed and compared at 4-6 years of age. RESULTS: The study involved 40 patients: 23 in group 1, nine in group 2 and eight in group 3. The number of patients who had been diagnosed with cerebral palsy was 13 in group 1, two in group 2, and one in group 3, which was a significant decrease. The number of patients with seizures and electroencephalography abnormality was 12 and 14 in group 1, three and two in group 2, and one and one in group 3, respectively, which was also a significant decrease. CONCLUSIONS: NRP courses have positive effects on short-term as well as long-term neurodevelopmental outcomes of infants with perinatal asphyxia. Further studies are required to determine the effects of NRP courses on minor deficits, such as cognitive and behavioral disturbances.

The relationship between leukemoid reaction and perinatal morbidity, mortality, and chorioamnionitis in low birth weight infants.

OBJECTIVES: Neonatal leukemoid reaction (NLR) is relatively rare and considered as a white blood cell (WBC) count ≥50×10(9)/l . The aim of this study was to investigate the association of NLR with neonatal morbidity and mortality and maternal chorioamnionitis in low birth weight infants. METHODS: In this case-controlled retrospective study, the medical records of 1200 newborn infants with a birth weight <2500g admitted to the neonatal unit over a period of 5 years were reviewed. The infants who developed features of NLR (n=17, 1.4%) formed the study group, while the remainder without NLR, matched for gestational age and birth weight (n=123), formed the control group. A chart review was performed and salient demographic, clinical, and laboratory data abstracted. A statistical analysis was subsequently performed on this data. RESULTS: The mean WBC and absolute neutrophil counts of infants with NLR were significantly higher than those in the control group. The peak time of NLR was at 7.9±3.6 (interquartile range (IQR) 1-30) days and on average it improved within 4.1±1.95 (IQR 2-9) days. It was noted that those infants with NLR were mostly born by vaginal delivery and their mothers had a higher rate of early rupture of the membranes and chorioamnionitis. NLR was associated with a 4-fold increase in sepsis, 20-fold increase in intraventricular hemorrhage, 54-fold increase in bronchopulmonary dysplasia, and 6-fold increase in mortality. In the study group, those infants whose mothers had chorioamnionitis had a higher rate of early rupture of the membranes and they developed sepsis and intraventricular hemorrhage more often than those whose mothers did not have clinical chorioamnionitis. CONCLUSIONS: In low birth weight newborn infants, NLR is significantly associated with sepsis, intraventricular hemorrhage, bronchopulmonary dysplasia, and a high mortality rate. Also, those infants with NLR are more likely to be born to mothers with chorioamnionitis and they face sepsis and intraventricular hemorrhage more often.
