A Comparison of Slow Infusion Intermittent Feeding versus Gravity Feeding in Preterm Infants: A Randomized Controlled Trial.

BACKGROUND: The transition to full enteral feeding is important for ensuring adequate growth in preterm infants. AIMS: The aim of this study was to investigate the effects of two different intermittent feeding methods on the transition to full enteral feeding in preterm infants. STUDY DESIGN: A prospective, randomized controlled study was conducted in a neonatology and perinatology center. SUBJECTS: Preterm infants with a gestational age between 24 + 0/7 and 31 + 6/7 were included in this study. They were divided into two groups: the SIF (slow infusion feeding) group and the IBF (intermittent bolus feeding) group. In the SIF group, feed volumes were administered over one hour using an infusion pump through an orogastric tube, with feeding occurring every three hours. The IBF group received enteral feeding using a gravity-based technique with a syringe through an orogastric tube, completed within 10 to 30 min. OUTCOME MEASURES: The primary outcome was the achievement of full enteral feeding and the occurrence of feeding intolerance. RESULTS: A total of 103 infants were enrolled in the study (50 in SIF and 53 in IBF). The time to achieve full enteral feeding did not differ significantly between the two groups (p = 0.20). The SIF group had significantly fewer occurrences in which gastric residual volume exceeded 50% (p = 0.01). Moreover, the SIF group had a significantly shorter duration of non-per-oral (NPO) status than the IBF group (p = 0.03). CONCLUSIONS: It is our contention that the use of the SIF method as an alternative feeding method is appropriate for infants with feeding intolerance and those at high risk of feeding intolerance.

Cycled Lighting Versus Continuous Near Darkness in Preterm Infants: A Randomized Controlled Trial.

OBJECTIVE: To compare the effectiveness of cycled lighting (CL) or continuous near darkness (CND) on weight in preterm infants. STUDY DESIGN: Total 147 infants with a gestational age 25-32 weeks and/or a birth weight 750-1500 g were included in the study. The infants were classified into two groups: CL and CND. Weight on postnatal day 14, weight at corrected 35 weeks, mean rectal temperature and serum growth hormone, cortisol, melatonin levels at 35 weeks' post menstrual age (PMA), weekly weight gain, full enteral feeding time, duration of mechanical ventilation, retinopathy of prematurity (ROP), length of stay in the hospital, weight and length at three and six months corrected age were compared between the groups. RESULTS: There were no differences between weights on postnatal day 14. Anthropometric parameters and mean rectal temperatures of groups also were not different at 35 weeks' PMA. There were no differences among the groups in duration of full enteral feeding time, length of stay in hospitalization, duration of mechanical ventilation, ROP and anthropometric parameters. Further, serum growth hormone, cortisol, and melatonin levels were similar between the groups at 35 weeks' PMA. CONCLUSION: CL and CND did not have any advantages over each other.

Prolonged minimal enteral nutrition versus early feeding advancements in preterm infants with birth weight ≤1250 g: a prospective randomized trial.

OBJECTIVE: To determine the effect of two different feeding strategies on time to achieve full enteral feeding and the incidence of feeding intolerance in preterm infants with birth weight ≤1250 g. METHODS: A prospective randomized trial (NCT02913677) conducted at a tertiary level neonatal intensive care unit. Preterm infants with birth weight ≤1250 g were randomly allocated to either prolonged minimal enteral nutrition (MEN) in which feed volumes were not increased for five days or early feeding advancement groups in which feed volumes were advanced by 20-25 ml/kg/d until 150 ml/kg/d feed volume was achieved. The primary outcomes were time to reach full enteral feeding sustained for 72 h and incidence of feeding intolerance. RESULTS: A total of 199 infants (99 in prolonged MEN and 100 in early feeding advancement groups) were involved in the study. No statistically significant differences were observed in time to achieve full enteral feeding and feeding intolerance. Daily weight gain (19 versus 16 g; p < .001) was significantly higher in prolonged MEN group. There were no significant differences in weight percentiles and z-scores at discharge. Duration of hospitalization was comparable between the groups. The overall incidence of late onset sepsis and culture proven sepsis was similar in both groups (p = .92 and p = .22, respectively). Incidence of necrotizing enterocolitis (NEC) was 5% in early feeding advancement group, whereas no case of NEC was observed in prolonged MEN group (p = .06). CONCLUSIONS: Prolonged MEN is not associated with a delay in time to achieve full enteral feedings. It may even provide an advantage for development of NEC in extremely low birth weight infants.

Comparison of Nasal CPAP versus Bi-level CPAP in Transient Tachypnea of the Newborn: A Randomized Trial.

OBJECTIVE: The optimal noninvasive ventilation (NIV) modality in the treatment of transient tachypnea of the newborn (TTN) is still unknown. The aim of this study was to compare nasal continuous positive airway pressure (NCPAP) versus bi-level CPAP in the treatment of TTN. STUDY DESIGN: This was a prospective randomized study that was conducted in a tertiary level neonatal intensive care unit of Zekai Tahir Burak Women's Health Education and Research Hospital during the 1-year period between April 2017 and March 2018. The study included infants at ≥34 gestational weeks and birth weight ≥2,000 g who were diagnosed with TTN. The patients were randomized to either NCPAP or bi-level CPAP groups as initial respiratory support. The primary outcome was the rate of NIV failure. RESULTS: A total of 151 infants were incorporated into the study. The intubation rate was significantly higher in the NCPAP group (15/75) compared with the bi-level CPAP group (6/76) (p = 0.032). There was a significant decrease in the level of pCO2 at the 12 (60.7 ± 6.7 vs. 66.3 ± 8.8, p = 0.017) and 24 (50 ± 8 vs. 53 ± 10, p = 0.028) hours of NIV in the bi-level CPAP group compared with the NCPAP group. Duration of NIV, total respiratory support, hospital stay, and the incidence of pneumothorax were similar between the groups. CONCLUSION: Bi-level CPAP reduced the rate of NIV failure and pCO2 levels at the 12 and 24 hours in late preterm and term infants with a diagnosis of TTN. KEY POINTS: · Bi-level CPAP seems to be a safe and effective method in TTN.. · Bi-level CPAP may reduce the rate of NIV failure in late preterm and term infants with TTN.. · Future studies are warranted to answer the question whether bi-level CPAP might be used as a standard treatment in babies with TTN..

Effect of withholding feeds on transfusion-related acute gut injury in preterm infants: a pilot randomized controlled trial.

Background: Several retrospective studies have reported an increase in necrotizing enterocolitis (NEC) during the 48 h following red blood cell (RBC) transfusion. Whether withholding enteral feeding during transfusion decreases the risk of transfusion-associated acute gut injury (TRAGI) in preterm infants is unclear.Study design and methods: In this pilot study, 112 preterm infants with gestational age ≤32 weeks and/or birth weight ≤1500 g were randomly assigned to withholding (NPO) or continuance of feeding (FED) during RBC transfusion. Primary outcome measure was development of NEC (stage ≥ 2) within 72 h of a transfusion and the change in abdominal circumference.Results: One hundred fifty-four transfusion episodes (74 NPO and 80 FED) were analyzed. Demographic characteristics were found to be similar in both groups. There was no difference in rates of NEC (0 versus 3.4%; p = .49) between the NPO and FED groups. The incidence of feeding intolerance was higher in the FED group; however, it was statistically insignificant (1.9 versus 6.8%, p = .36). Abdominal circumference remained similar in both groups in all three consecutive days following transfusion (p>.05).Conclusion: This pilot study does not support withholding feedings during transfusion but is not adequately powered to test the hypothesis that NPO decreases NEC rates. Adequately powered well-designed multicenter trials are still required.

Can Base Excess be Used for Prediction to Early Diagnosis of Neonatal Sepsis in Preterm Newborns?

BACKGROUND: Neonatal sepsis remains an important and potentially life-threatening clinical syndrome and a major cause of neonatal mortality and morbidity. The aim of this study to investigate whether values of base excess before the onset of clinical signs and symptoms of sepsis indicate infection in the early diagnosis of neonatal sepsis. METHODS: In this study, a total of 118 infants were enrolled. The infants were classified into two groups: group 1 (sepsis, n=49) and group 2 (control, n=69). Blood gas analysis investigated for the screening of neonatal sepsis. RESULTS: A total of 49 newborns with neonatal sepsis and 69 healthy controls were enrolled. Comparison of markers of sepsis revealed C-reactive protein, interleukin-6 level to be significantly higher and pH, pCO2, HCO3, and base excess values to be significantly lower in newborns with sepsis compared healthy controls (p<0.01). The optimum cut-off value in the diagnosis of neonatal sepsis was found to be -5 mmol/L for base excess. Sensitivity, specificity, positive predictive value and negative predictive value of this base excess cut-off for neonatal sepsis were 75, 91, 86 and 84% respectively. CONCLUSION: This is the first study to determine the relationship between the decreased value of the base excess and early stage of neonatal sepsis. If the value of base excess <-5 mmol/L without an underlying another reason, may need close follow up of infants for neonatal sepsis and it may help early diagnosis.

Lung Lavage with Dilute Surfactant vs. Bolus Surfactant for Meconium Aspiration Syndrome.

OBJECTIVE: To compare the effectiveness of lung lavage with surfactant vs. bolus surfactant treatment in meconium aspiration syndrome (MAS). PATIENTS AND METHODS: This randomized controlled trial included newborns ventilated with MAS. In lavage group (n = 17) 30 ml/kg of diluted porcine surfactant was instilled into the lung. In bolus group (n = 16) porcine surfactant (100 mg/kg) was administered as bolus. Respiratory outcomes and mortality were compared between groups. RESULTS: Duration of respiratory support was found to be similar between lavage and bolus groups (3 vs. 3.5 days, p = 0.36). Death or requirement for extracorporeal membrane oxygenation (ECMO) was 12% vs. 6%; respectively (RR: 2, 95% CI 0.16-24.48; p = 1.0). Duration of oxygen therapy, high-frequency ventilation or inhaled nitric oxide requirement did not differ among the groups. CONCLUSION: Lung lavage did not show any advantage over bolus therapy on duration of respiratory support. The incidence of pneumothorax and surfactant re-administration decreased nonsignificantly in lavage group. CLINICAL TRIAL REGISTRATION: We registered the trial to ClinicalTrials.gov (http://clinicaltrials.gov) under identifier NCT02041546. REGISTRY NAME: Lung Lavage With Dilute Poractant Alfa for Meconium Aspiration Syndrome.

Comparison of the Effect of Three Different Fortification Methods on Growth of Very Low Birth Weight Infants.

BACKGROUND: This study aimed to compare the effects of adjustable fortification (AF), targeted fortification (TF), and standard fortification (SF) methods on the early growth of very low birth weight infants. MATERIALS AND METHODS: Sixty infants <32 weeks of gestational age and weighing <1,500 g were selected. These infants were exclusively fed with breast milk and were randomized into three fortification groups: SF, AF, and TF. SF consists of adding a fixed amount of fortifier to maternal milk. Blood urea nitrogen levels are used to adjust fortifier in AF. In TF, breast milk is analyzed and fortified accordingly based on the macronutrient content to achieve the targeted intake. RESULTS: A total of 76 preterm infants were eligible for the study. Sixty infants were randomized into three groups. At the end of the fourth week of fortification period, median daily weight gain of the infants was similar in the AF [23.5 g/(kg·d)] and TF groups [25.5 g/(kg·d)], and significantly higher in both groups than in SF group [12 g/(kg·d)] (AF versus SF group, p < 0.001 and TF versus SF group, p < 0.001). Weight, head circumference, and length were compared across the three groups regarding percentile. Significant improvement in the percentile groups of weight and head circumference was observed in the AF and TF groups. In the SF group, a significant decline in the percentile groups of weight, head circumference, and length was detected. Daily protein and energy intakes in AF and TF groups were significantly higher than those in SF group (SF versus AF, p < 0.001 and SF versus TF, p < 0.001). CONCLUSIONS: Fortifying breast milk with AF and TF methods was found to improve body weight, length, and head circumference percentiles of preterm infants, whereas SF method was found unsatisfactory. To provide optimum growth for preterm babies, breast milk that has been fortified by using AF and TF strategies should be recommended in neonatal intensive care units.

Does prenatal diagnosis of critical congenital heart diseases influence the prereferral mortality in a center without surgical intervention?

Background: Prenatal diagnosis ameliorates some preoperative and postoperative outcomes in critical congenital heart disease (CHD). Despite large variability among anatomical defect types, nearly half of them are diagnosed antenatally. We aimed to investigate the effect of the antenatal diagnosis on prereferral mortality of infants with critical CHD in a center without cardiovascular surgery clinic. Methods: Medical records of the neonates who were diagnosed with critical CHD between the years 2010 and 2016 in Zekai Tahir Burak Women's health Education and Research Hospital were retrospectively reviewed for the study. Patients were divided in two groups as prenatal and postnatal regarding the time of diagnosis. Groups were compared in terms of demographical, clinical characteristics, and prereferral mortality rates. Results: Seventy seven neonates were included in the study. Of those, 39 (50%) infants had prenatal diagnosis. Most common types of CHD were tetralogy of Fallot (TOF) with pulmonary atresia, hypoplastic left heart syndrome (HLHS), and transposition of the great arteries (TGA), respectively. Demographical and clinical characteristics were similar between the groups. Minor congenital anomalies were more common in the patients with prenatal diagnosis (41 versus 18%, p = .021). Blood gas parameters were similar except pCO2 levels, which were slightly lower in the postnatal diagnosis group (p = .048). There was no difference with regard to prereferral mortality between prenatal and postnatal diagnosed infants. Conclusions: Prenatal diagnosis may not be always associated with improved survival in critical CHD in a center without immediate surgical intervention opportunity.

The association of early postnatal weight loss with outcome in extremely low birth weight infants.

BACKGROUND: To compare outcomes of extremely low birth weight (ELBW) infants having different weight losses in the first 3 days of life. METHODS: One hundred and twenty six ELBW infants were evaluated retrospectively for weight loss percentages on the third day of life compared to their birth weight. We examined the weight loss on the third day of life compared to the birth weight for the ELBW infants and tested its association with mortality and morbidities. The mortality was subgrouped as overall mortality and mortality in the first 7 days of life. The morbidities were patent ductus arteriosus (PDA), intraventricular hemorrhage (IVH) and bronchopulmonary dysplasia (BPD). BPD was defined as need for supplemental oxygen at 36 weeks' postconceptional age. We grouped the infants into four quartiles according to weight loss percentage on the third day of life: Group 1 (Quartile 1), infants with weight loss of 0-3% of birth weight; Group 2 (Quartile 2); infants with weight loss of 3.1-7.5%, Group 3 (Quartile 3), infants with weight loss of 7.51-12%; and Group 4 (Quartile 4), infants with weight loss of more than 12%. The mortality and morbidities were analyzed according to these groups and other risk factors. RESULTS: Overall mortality and mortality in the first 7 days of life were significantly higher in Groups 1 (36% and 27%) and 4 (43% and 24%), compared to Groups 2 (10% and 10%) and 3 (18% and 9%), respectively. CONCLUSION: Weight loss less than 3% and more than 12% was significantly associated with an increase in mortality. There was a positive correlation between weight loss on the third day of life and IVH. CONCLUSION: Inappropriate weight loss in ELBW infants is associated with increased mortality and IVH. Appropriate weight loss can improve outcomes in this population.

Mean platelet volume/count and mortality in extremely low birth weight infants of preeclamptic mothers.

PURPOSE: To compare complete blood count (CBC) parameters in extremely low birth weight (ELBW) infants born to mothers with and without preeclampsia and to evaluate whether these parameters could be used to determine the prognosis of infants born to mothers with preeclampsia. METHOD: Thirty-eight infants of preeclamptic mothers (IPM) and 77 infants of non-preeclamptic mothers (INPM) were included in the study. The CBC parameters of ELBW infants were evaluated at the sixth hour of life. RESULTS: The mean hemoglobin level of the IPM group was higher than the INPM group (16.4±2.4 vs 15.3±2.4; p=0.02). The mean platelet count of the IPM Group was significantly lower than the INPM group (168±65 vs 206±78; p=0.008). Overall and 7th day of life survival of infants were not different between the groups, but there was a correlation between platelet count of the IPM group and mortality in the first 7 days of life and overall mortality (r=-0.38, p=0.023 and r=-0.36, p=0.029). A cut-off point of 0.4 had significant predictive value for mortality (sensitivity of 91%, specificity of 66%). CONCLUSION: Hemoglobin and platelet counts were statistically different in ELBW infants born to preeclamptic mothers compared with non-preeclamptic mothers. Although the survival was not different between the two groups, platelet count and MPV/platelet count ratio were significantly correlated with overall mortality and mortality in the first 7 days of life in infants of preeclamptic mothers.

Evaluation of prolonged pain in preterm infants with pneumothorax using heart rate variability analysis and EDIN (Échelle Douleur Inconfort Nouveau-Né, neonatal pain and discomfort scale) scores.

PURPOSE: The EDIN scale (Échelle Douleur Inconfort Nouveau-Né, neonatal pain and discomfort scale) and heart rate variability has been used for the evaluation of prolonged pain. The aim of our study was to assess the value of the newborn infant parasympathetic evaluation (NIPE) index and EDIN scale for the evaluation of prolonged pain in preterm infants with chest tube placement due to pneumothorax. METHODS: This prospective observational study assessed prolonged pain in preterm infants with a gestational age between 33 and 35 weeks undergoing installation of chest tubes. Prolonged pain was assessed using the EDIN scale and NIPE index. RESULTS: There was a significant correlation between the EDIN scale and NIPE index (r=-0.590, P=0.003). Prolonged pain is significantly more severe in the first 6 hours following chest tube installation (NIPE index: 60 [50-86] vs. 68 [45-89], P<0.002; EDIN score: 8 [7-11] vs. 6 [4-8], P<0.001). CONCLUSION: Prolonged pain can be accurately assessed with the EDIN scale and NIPE index. However, evaluation with the EDIN scale is time-consuming. The NIPE index can provide instantaneous assessment of prolonged and continuous pain.

Turkish Neonatal Society guideline on the management of patent ductus arteriosus in preterm infants.

Ductus arteriosus is a physiologic phenomenon in utero and it closes spontaneously in term babies. The closure is problematic in preterm infants due to the intrinsic properties of the preterm ductus arteriosus tissue. Although patent ductus arteriosus has been reported to be associated with many adverse outcomes in this population, treatment has not led to a decrease in outcomes such as bronchopulmonary dysplasia. Treatment modalities also have their own risks and restrictions. The aim of the "Turkish Neonatal Society guidelines for the management of patent ductus arteriosus in preterm babies" is to standardize the diagnosis and treatment of patent ductus arteriosus in preterm infants by combining the current scientific data and the resources of our country.

Successful Implementation of a Bundle Strategy to Prevent Ventilator-Associated Pneumonia in a Neonatal Intensive Care Unit.

BACKGROUND: We aimed to investigate the effectiveness of evidence-based bundle that we developed to reduce ventilator-associated pneumonia (VAP) rates and to assess the degree of compliance rates to this strategy in a tertiary neonatal intensive care unit. METHODS: This before-after prospective cohort trial divided into two periods was conducted. All neonates requiring ventilation were enrolled in the study. VAP incidence, compliance rates to bundle components and the contribution of each bundle component to VAP rates were compared between the periods. RESULTS: Throughout the study period, 13 VAP episodes were observed. Full adherence to all six components of the bundle doubled in the active-bundle period (12.8 vs. 24.3%, p < 0.01). The mean VAP rate decreased from 7.33/1000 to 2.71/1000 ventilator days following intervention (p = 0.083). CONCLUSION: This study showed that reliable implementation of a neonate-specific VAP prevention bundle can produce sustained reductions in VAP rates.

Effects of cord blood vitamin D levels on the risk of neonatal sepsis in premature infants.

PURPOSE: Vitamin D plays a key role in immune function. Vitamin D deficiency may play a role in the pathogenesis of infections, and low levels of circulating vitamin D are strongly associated with infectious diseases. In this study, we aimed to evaluate the effects of low vitamin D levels in cord blood on neonatal sepsis in preterm infants. METHODS: One hundred seventeen premature infants with gestational age of <37 weeks were enrolled. In the present study, severe vitamin D deficiency (group 1) was defined as a 25-hydroxyvitamin D (25(OH)D) concentration <5 ng/mL; vitamin D insufficiency (group 2), 25(OH)D concentration ≥5 ng/mL and <15 ng/mL; and vitamin D sufficiency (group 3), 25(OH)D concentration ≥15 ng/mL. RESULTS: Sixty-three percent of the infants had deficient levels of cord blood vitamin D (group 1), 24% had insufficient levels (group 2), and 13% were found to have sufficient levels (group 3). The rate of neonatal sepsis was higher in group 2 than in groups 1 and 3. CONCLUSION: There was no significant relationship between the cord blood vitamin D levels and the risk of neonatal sepsis in premature infants.

Multi-dose vitamin d supplementation in stable very preterm infants: Prospective randomized trial response to three different vitamin D supplementation doses.

BACKGROUND: Preterm newborns are born with lower vitamin D stores. Although vitamin D supplementation is recommended there is no consensus regarding the adequate dose of supplementation for preterm infants. AIMS: To assess the effect of three different doses of vitamin D supplementation (400, 800 and 1000IU/d) in preterm infants ≤32weeks gestation on the prevalence of vitamin D deficiency and 25(OH) D levels at 36weeks postmenstrual age (PMA). STUDY DESIGN: Prospective randomized trial. SUBJECTS: 121 preterm infants with gestational age of 24-32weeks were randomly allocated to receive 400, 800 or 1000IU/d vitamin D. OUTCOME MEASURES: Serum concentration of 25(OH) D and the prevalence of vitamin D deficiency at 36weeks PMA. Vitamin D deficiency was defined as serum 25(OH) D concentrations <20ng/ml. RESULTS: Of the 121 infants 72% had deficient vitamin D levels before supplementation. The average 25(OH) vitamin D concentrations at 36weeks PMA were significantly higher in 800IU (40±21.4ng/ml) and 1000IU group (43±18.9ng/ml) when compared to 400IU group (29.4±13ng/ml). The prevalence of vitamin D deficiency (2.5 vs 22.5; RR: 0.09; CI:0.01-0.74) and insufficiency (30 vs 57.5; RR:0.32; CI:0.13-0.80) was significantly lower in 1000IU group when compared to 400IU group at 36weeks PMA. CONCLUSION: 1000IU/d of vitamin D supplementation in preterm infants ≤32weeks gestation age effectively decreases the prevalence of vitamin D deficiency and leads to higher concentrations of 25(OH) vitamin D at 36weeks PMA TRIAL REGISTRATION: Clinical Trials.gov: NCT02941185.

Neurodevelopmental Outcomes of Preterm Infants Treated with Oral Paracetamol Versus Ibuprofen for Patent Ductus Arteriosus.

Objective This study aims to determine the effects of paracetamol versus ibuprofen treatment given to preterm infants for the pharmacological closure of patent ductus arteriosus (PDA) on neurodevelopmental outcomes at 18 to 24 months' corrected age. Method A follow-up study was conducted to evaluate the neurodevelopmental outcomes of preterm infants (gestational age ≤ 30 weeks) enrolled in a randomized controlled trial comparing oral paracetamol versus oral ibuprofen for the closure of PDA. The developmental assessment was done by using "Bayley Scales of Infant Development, Second Edition" at 18 to 24 months' corrected age. Results A total of 80 infants completed the trial protocol. Of the 75 infants eligible for follow-up, 61 infants (30 in the paracetamol group and 31 in the ibuprofen group) were evaluated. There was no significant difference in neurodevelopmental outcomes between the two groups. Conclusion The neurodevelopmental outcomes did not differ among the preterm infants who receive either paracetamol or ibuprofen at 18 to 24 months' corrected age.
