Effects of aggressive parenteral nutrition on growth and clinical outcome in preterm infants

The goal of nutrition in the preterm infant is to achieve postnatal growth approximating normal fetal growth. During the early postnatal period, protein intake must be sufficient to achieve normal postnatal growth in extremely low‐birthweight infants. The aim of this study was to test the hypothesis that giving higher amounts of amino acids and lipids to infants born at <34 gestational weeks (GW) may improve growth at the 40th week of gestation and have a positive preventive effect on development of retinopathy of prematurity (ROP).

Effect of low versus high early parenteral nutrition on plasma amino acid profiles in very low birth-weight infants

Objective: To study the efficacy of early high doses parenteral nutrition (PN) versus early low dose with progressive increments PN regimens, we performed a prospective randomized study in very low birth-weight infants. Study design: Forty-one appropriate gestational age preterm infants with birth weights ranging from 750–1500 g were randomly assigned into two groups. In Group 1, infants started on 3.0 g/kg/day amino acids (AA) and 3 g/kg/day of 20% lipid; in Group 2, AA and lipid were started on 1 g/kg/day, and advanced over 3 days to a maximum 3 g/kg/day. Blood samples were obtained for AA concentrations before starting of the PN, and at the 7th and 14th days. Results: The mean (±SD) birth weight was 1335 g (240), gestational age was 29.7 weeks (1.7) of the study group. The mean body weight and head circumference was similar in the Group 1 and Group 2 at the 14th postnatal days. There was no difference in the blood levels of triglyceride, blood urea nitrogen, creatinine, ammonia, lactat and bicarbonate in the two groups. There was no significant difference in the concentrations of AA except for arginine and asparagine. On day 14, the mean arginine concentrations were significantly higher and asparagine concentrations were lower in Group 2. Conclusion: Although earlier more aggressive administration of AA and fat is not associated with any significant metabolic abnormalities, growth rates and plasma AA concentrations of the infants were similar to infants who AA and lipid given lower in the first day of life.

Acute kidney injury in a single neonatal intensive care unit in Turkey.

BackgroundAlthough advances in perinatal medicine have increased the survival rates of critically ill neonates, acute kidney injury (AKI) is still one of the major causes of mortality and morbidity in neonatal intensive care units. This study aimed to determine the prevalence of AKI and analyze demographic data and risk factors associated with the mortality or morbidity.MethodsOf 1992 neonates hospitalized between January 2009 and January 2011, 168 with AKI were reviewed in the study. The diagnosis of AKI was based on plasma creatinine level >1.5 mg/dL, which persists for more than 24 hours or increases more than 0.3 mg/dL per day after the first 48 hours of birth while showing normal maternal renal function.ResultsThe prevalence of AKI was 8.4%. The common cause of AKI was respiratory distress syndrome, followed by sepsis, asphyxia, dehydration, congenital anomalies of the urinary tract, congenital heart disease, and medication. The prevalence of AKI in neonates with birth weight lower than 1500 g was about three-fold higher than in those with birth weight higher than 1500 g (P<0.05). Pregnancy-induced hypertension, preterm prolonged rupture of membranes, and administration of antenatal corticosteroid were associated with increased risk of AKI (P<0.05). Umbilical vein catheterization, mechanical ventilation and ibuprofen therapy for patent ductus arteriosus closure were found to be associated with AKI (P<0.05). The overall mortality rate was 23.8%. Multivariate analysis revealed that birth weight less than 1500 g, mechanical ventilation, bronchopulmonary dysplasia, anuria, and dialysis were the risk factors for the mortality of infants with AKI.ConclusionsPrenatal factors and medical devices were significantly associated with AKI. Early detection of risk factors can reduce the mortality of AKI patients.

Idiopathic congenital chylothorax presented with severe hydrops and treated with octreotide in term newborn

Chylothorax is a relatively uncommon condition defined as an abnormal collection of lymphatic fluid within the pleural space. Morbidity of congenital chylothorax (CC) is high, and prognosis is very poor if chylothorax is associated with hydrops fetalis. The optimal treatment of CC has not been defined. Conservative treatment (low-fat high-protein diets with medium chain triglycerides, total parenteral nutrition, pleural drainage) and surgical intervention are performed. However, there is little experience with the use of octreotide therapy in this condition. We report a newborn with CC presented with severe non-immune hydrops and chylothorax resistant to mainly conservative treatment. The patient improved rapidly and the chylothorax disappeared with use of continuous administration of octreotide (10 μg/kg/per hour).

A Comparison of Different Methods of Temperature Measurements in Sick Newborns

We aimed to compare the accuracy of digital axillary thermometer (DAT), rectal glass mercury thermometer (RGMT), infrared tympanic thermometer (ITT) and infrared forehead skin thermometer (IFST) measurements with traditional axillary glass mercury thermometer (AGMT) for intermittent temperature measurement in sick newborns. A prospective, descriptive and comparative study in which five different types of thermometer readings were performed sequentially for 3 days. A total of 1989 measurements were collected from 663 newborns. DAT and ITT measurements correlated most closely to AGMT (r = 0.94). The correlation coefficent for IFST and RGMT were 0.74 and 0.87, respectively. The mean differences for DAT, ITT, RGMT and IFST were +0.02°C, +0.03°C, +0.25°C and +0.55°C, respectively. There were not any clinical differences (defined as a mean difference of 0.2°C) between both mean AGMT&DAT and AGMT&ITT measurements. Our study suggests that tympanic thermometer measurement could be used as an acceptable and practical method for sick newborn in neonatal units.

A Comparison of Magnesium Sulphate and Sildenafil in the Treatment of the Newborns with Persistent Pulmonary Hypertension: A Randomized Controlled Trial

The aim of this prospective, randomized and controlled study was to compare the clinical efficacy of intravenous magnesium sulfate (MgSO₄) and oral sildenafil therapies with persistent pulmonary hypertension of the newborn. A total of 34 infants in the MgSO₄ group and 31 infants in the sildenafil group completed the study. The time to reach the adequate clinical response [defined as oxygen index (OI) level of <15, a pulmonary artery pressure of < 20 mmHg) was significantly shorter in the sildenafil group (p = 0.002). Duration of mechanical ventilation was longer and the number of the patients requiring inotropic support was higher in the MgSO₄ group (p = 0.001 and p = 0.002, respectively). Although among two groups the difference in OI > 5 as speculated in our hypothesis could only be found at 36 h of the treatment, sildenafil was more effective than MgSO₄ in the treatment of persistent pulmonary hypertension of the newborns with regard to time to adequate clinical response, duration of mechanical ventilation and support requirement with inotropic agents.

Clinical Characteristics of Neonatal Meningomyelocele Cases and Effect of Operation Time on Mortality and Morbidity

Objective: We aimed to evaluate the clinical features, short-term prognosis, and effect of operation time on mortality and morbidity in neonates with meningomyelocele. Methods: This prospective study was conducted between January 2006 and December 2008. Clinical features, defective area, existence of additional anomalies, operation time, and morbidity and mortality data were recorded. The effectof operation time on mortality and morbidity was evaluated. Results: Patients (n = 28) were assessed during the study period. Mean birth weight, height, and head circumference were found to be 3,160 ± 582 g, 46.2 ± 3.3 cm, and 36.7 ± 4.1 cm, respectively. None of the mothers received folate supplementation. Hydrocephaly (n = 13), pes equinovarus (n = 4), pelvicalyceal ectasia (n = 4), acetabular dysplasia (n = 2), Chiari II malformation (n = 2), and hydronephrosis (n = 2) accounted for additional anomalies. The mean postnatal age for surgical operation was 3.2 ± 2.8 days; mean length of hospital stay was 10.2 ± 9.7 days. The cases operated after 72 h were hospitalized longer, received antibiotherapies for a longer duration and had higher total complication rates (p = 0.04, 0.02, and 0.01, respectively). Conclusion: Surgical operation of patients with meningomyelocele within 72 h after delivery significantly reduces not only the duration of hospitalization and antibiotic usage, but also complication rates.

Neonatal Infection with Neisseria meningitidis: Analysis of a 97-Year Period Plus Case Study

ABSTRACT Neisseria meningitidis is one of the major causes of meningitis in children and adolescents, but it is rarely found during the neonatal period. Here, we describe a neonate with meningococcal sepsis who was admitted to the hospital on postnatal day 10, and we discuss the clinical features of neonatal infection with N. meningitidis in relation to the literature (analysis of a 97-year period).

Percutaneously inserted central catheters in the newborns: A center's experience in Turkey

Objective. To evaluate the success rate of insertion of percutaneously inserted central catheters (PICCs) and their duration; and the short- and long-term complications in the neonatal period. Study design. We did a prospective collection and analysis of the data of all infants who underwent PICC placement from January 2005 and through January 2007. During this period there were 139 PICCs inserted in a total of 124 infants. The data of all infants were compiled, including birth weight, gestational age, diagnosis, type of catheter, site of catheter placement, reason for catheter removal, duration of use of the catheter, and the rate of complications. Results. The success rate of PICC insertion was 88.5% with the upper extremity being the most frequently used site. The mean duration of PICC treatment was 11.9 ± 6.3 days. PICCs were removed electively for 72 times (54.1%) and due to catheter-related complications for 61 times (45.9%). The main complication rate was the mechanical occlusion (12.7%). There were no statistically significant differences in the number of complication rates according to the insertion site, the position of the catheter tip, or the size of the catheter. Conclusion. Our initial experience with PICCs is that their use provides life-saving therapy, they are easily inserted and they are convenient. Mechanical complications were the common reason for removal and we did not see complications more serious.

Healthcare-associated Infections in a Neonatal Intensive Care Unit in Turkey.

ObjectiveTo determine the incidence, risk factors, mortality rate, antibiotic susceptibility and causative agents of healthcare-associated infections (HAIs) in the Neonatal Intensive Care Unit.DesignProspective, cohort.SettingA 38-bed, teaching, referral, neonatal intensive-care unit.ParticipantsAll patients in the neonatal intensive care unit who did not have any sign of infection at admission and remained hospitalized for at least 48 hours.MethodsThe study was conducted between January 2009 and January 2011. Healthcare-associated infection was diagnosed according to the criteria of CDC. Risk factors for HAI were analyzed with univariate and multivariate regression analysis.ResultsThe incidence of HAI was found to be 16.2%. Blood stream infection was observed as the most common form of HAI (73.2%). The mortality rate was 17.3%. Antenatal steroid use, cesarean section, male gender, low birth weight, parenteral nutrition, percutaneous and umbilical catheter insertion, mechanical ventilation and low Apgar scores were found to be related with HAI (P<0.05). A 10% reduction in infection rate as a consequence of the application of a new total parenteral nutrition guideline was observed. Coagulase negative staphylococci (44. 4%) and Klebsiella pneumoniae (25.9%) were the most common etiologic agents isolated from cultures. Methicillin resistance of coagulase-negative staphylococci and ESBL resistance of Klebsiella pneumoniae were 72% and 44%, respectively.ConclusionsAntenatal steroid was found to be associated with HAI. Newly applied total parenteral nutrition guidelines reduced the attack rate of infection. Efforts should be focused on developing more effective prevention strategies to achieve better outcomes.
