Changes over time in delivery room management of extremely low birth weight infants in Italy

AIM To identify changes in practice between two historical periods (2002 vs. 2011) in early delivery room (DR) management of ELBWI in Italian tertiary centres. METHODS A questionnaire was sent to the directors of all Italian level III centres between April and August 2012. The same questionnaire was used in a national survey conducted in 2002. Among the participating centres, those that filled the questionnaire in both study periods were selected for inclusion in this study. RESULTS There was an 88% (n=76/86) and 92% (n=98/107) response rate in the 2 surveys, respectively. The two groups overlapped for 64 centres. During the study period, the use of polyethylene bags/wraps increased from 4.7% to 59.4% of the centres. The units using 100% oxygen concentrations to initiate resuscitation of ELBWI decreased from 56.2% to 6.2%. The approach to respiratory management was changed for the majority of the examined issues: positive pressure ventilation (PPV) administered through a T-piece resuscitator (from 14.0% to 85.9%); use of PEEP during PPV (from 35.9% to 95.3%); use of CPAP (from 43.1% to 86.2%). From 2002 to 2011, the percentages of ELBWI intubated in DR decreased in favor of those managed with N-CPAP; ELBWI receiving chest compressions and medications at birth were clinically comparable. CONCLUSIONS During the two study periods, the approach to the ELBWI at birth significantly changed. More attention was devoted to temperature control, use of oxygen, and less-invasive respiratory support. Nevertheless, some relevant interventions were not uniformly followed by the surveyed centres.

Fortification of maternal milk for preterm infants.

During the last few decades, neonatal survival rates for preterm infants have markedly been improved. The American Academy of Pediatrics recommended that preterm neonates should receive sufficient nutrients to enable them to grow at a rate similar to that of fetuses of the same gestational age. Although human milk is the recommended nutritional source for newborn infants for at least the first six months of postnatal life, unfortified human breast milk may not meet the recommended nutritional needs of growing preterm infants. Human milk must therefore be supplemented (fortified) with the nutrients in short supply. The fortification of human milk can be implemented in two different forms: standard and individualized. The new concepts and recommendations for optimization of human milk fortification is the “individualized fortification”. Actually, two methods have been proposed for individualization: the “targeted/tailored fortification” and the “adjustable fortification”. In summary, the use of fortified human milk produces adequate growth in premature infants and satisfies the specific nutritional requirements of these infants. The use of individualized fortification is recommended.

Oxygen administration for the resuscitation of term and preterm infants

Oxygen has been widely used in neonatal resuscitation for about 300 years. In October 2010, the International Liaison Committee on Neonatal Resuscitation released new guidelines. Based on experimental studies and randomized clinical trials, the recommendations on evaluation and monitoring of oxygenation status and oxygen supplementation in the delivery room were revised in detail. They include: inaccuracy of oxygenation clinical assessment (colour), mandatory use of pulse oximeter, specific saturation targets and oxygen concentrations during positive pressure ventilation in preterm and term infants. In this review, we describe oxygen management in the delivery room in terms of clinical assessment, monitoring, treatment and the gap of knowledge.

Delivery room management of extremely low birthweight infants shows marked geographical variations in Italy

To evaluate any geographical variations in practice and adherence to international guidelines for early delivery room management of extremely low birthweight (ELBW) infants in the North, Centre and South of Italy.

Fortification of maternal milk

The beneficial effects of human milk (HM), well recognized for the term infant, extend to the feeding of premature infants, because their nutrition support must be designed to compensate for metabolic and gastrointestinal immaturity, immunologic compromise, and maternal psycosocial conditions. Studies show that preterm milk contains higher protein levels and more fat than term human milk. The American Academy of Pediatrics recommended that preterm neonates should receive sufficient nutrients to enable them to grow at a rate similar to that of fetuses of the same gestational age. There are no doubts about the fact that maternal milk is the best food for all neonates, but unfortified human breast milk may not meet the recommended nutritional needs of growing preterm infants. Human milk must therefore be supplemented (fortified) with the nutrients in short supply. The objective of fortification is to increase the concentration of nutrients to such levels that at the customary feeding volumes infants receive amounts of all nutrients that meet the requirements. The are two different forms of fortification of human milk: standard and individualized. The new concepts and recommendations for optimization of human milk fortification is the “individualized fortification”. Actually, two methods have been proposed for individualization: the “targeted/tailored fortification” and the “adjustable fortification”. In summary, the use of fortified human milk produces adequate growth in premature infants and satisfies the specific nutritional requirements of these infants. The use of individualized fortification is recommended.

Broad-spectrum light versus blue light for phototherapy in neonatal hyperbilirubinemia: a randomized controlled trial.

Phototherapy is standard care for treatment of neonatal hyperbilirubinemia. Our aim was to compare the effectiveness of broad-spectrum light (BSL) to that of blue light emitting diodes (LED) phototherapy for the treatment of jaundiced late preterm and term infants. Infants with gestational age from 35(+0) to 41(+6) weeks of gestation and nonhemolytic hyperbilirubinemia were randomized to treatment with BSL phototherapy or blue LED phototherapy. A total of 20 infants were included in the blue LED phototherapy group and 20 in the BSL phototherapy group. The duration of phototherapy was lower in the BSL than in the blue LED phototherapy group (15.8 ± 4.9 vs. 20.6 ± 6.0 hours; p = 0.009), and infants in the former group had a lower probability (p = 0.015) of remaining in phototherapy than infants in the latter. We concluded that BSL phototherapy is more effective than blue LED phototherapy for the treatment of hyperbilirubinemia in late preterm and term infants. Our data suggest that these results are not due to the different irradiance of the two phototherapy systems, but probably depend on their different peak light emissions.

16 COLOR DOPPLER ECHOENCEPHALOGRAPHY

From January to December 1990, 100 color doppler echoencephalograms were obtained in 40 infants without cardiopulmonary affections and with a mean birth weight of 2940g (range 1760-3420 g), a mean gestational age of 37.2 weeks (range 34-40w). The examinations were performed using a real-time 2-D Doppler Scanner and a 3,75 MHz sector transducer. Serial scans were obtained in sagittal, coronal and axial plans. Detection rate of intracranial vessels was: internal carotid, anterior cerebral, pericallosal, basilar, vertebral artery (100%); callosomarginal artery (90%); frontopolar artery (82%); medial and lateral striate artery (17%); internal, great cerebral vein(GCV) and straight sinus (SS) (100%); superior sagittal sinus (69%); occipital sinus (39%). Flow mean velocity of GCV and SS was 6-10 and 15-24 cm/sec respectively. Usually vein curve has a continuous profile (therefore we can calculate only mean velocity) while sometimes, expecially in the biggest vein (SS), we observe particular aspects of vein flow similar to arterys one with a sort of systolic and diastolic phase. Probably this waving venous curve is within respiratory control becouse the “squeeze” of superior cava vein may induce an increase of vein flow velocity during inspiration.

Early ultrasonographic follow up in neonatal pneumatocele. Two case reports

Abstract Pulmonary pneumatocele is a thin-walled, air-filled cyst originating spontaneously within the lungs’ parenchyma, generally after infections or prolonged mechanical respiratory support. The diagnosis of pneumatocele is usually made using both chest X-ray (CXR) and computed tomography (CT) scan. Lung ultrasonography (LUS) is a promising technique used to investigate neonatal pulmonary diseases. We hereby present two cases of pneumatocele in newborns with respiratory distress syndrome (RDS) in which CXR and LUS were used to evaluate pulmonary parenchyma. LUS showed a multilobed cyst with a thin hyperechoic wall and a hypoechoic central area. Repeated LUS demonstrated a progressive reduction of the cyst’s size. After a few weeks, the small lesions were no longer detectable by ultrasound, therefore CXR was used, for follow-up, in the following months, until complete resolution. No data are available in the literature regarding ultrasonographic follow-up of neonatal pneumatocele. A larger number of patients are required to confirm our results and increase the use of LUS in the neonatal intensive care units (NICUs) to reduce neonatal radiations exposure.

Severe neurologic and hepatic toxicity in a newborn prenatally exposed to methamphetamine. A case report

OBJECTIVE In the recent years the increase of methamphetamines (MTA) abusers women has become an emerging problem. Very little data has been published regarding the effects of prenatal MTA exposure. We describe a case of MTA related toxicity in a term newborn which have early onset of neonatal encephalopathy and liver failure. CASE REPORT A term infant born to a MTA abuser mother developed seizures and severe neurological symptoms shortly after birth. Methamphetamine was detected both in maternal and in neonatal urine. The laboratoristic tests revealed severe hepatic insufficiency, coagulopathy and thrombocytopenia. Due to neonatal encephalopathy the newborn underwent hypothermia. Phenobarbital, fresh frozen plasma, platelet transfusions and vitamin K were administered. Cranial ultrasonography and magnetic resonance imaging (MRI) showed diffuse white matter damage and two ischemic-hemorrhagic cerebral lesions. Gradually the clinical conditions improved, at 1 month MRI showed a stabilization of cerebral lesions with residual diffuse leukomalacia. Physiotherapy and neurological follow up is ongoing to evaluate the long term effects. CONCLUSIONS although infrequent, MTA-related toxicity should be suspected in infants with neurologic and hepatic symptoms. Further studies are warranted to confirm our findings in order to identify newborns at high risk of acute MTA toxicity in time to provide them the appropriate support.

How to manage fetomaternal hemorrhage? Description of five cases and literature review

Fetomaternal hemorrhage (FMH) is a poorly understood condition in which there is a transfer of fetal blood to the maternal circulation. It occurs in approximately 1-3 per 1,000 births. We described five cases with characteristics suggestive of both acute and chronic anemia. When FMH is suspected, maternal blood can be checked for the presence of fetal red blood cells and usually there are three diagnostic modalities: Kleihauer-Betke test, flow cytometry and Rosette test. The clinical manifestations and the prognosis of FMH depend on the gestational age, the volume of the hemorrhage and the rapidity with which it has occurred. Red blood transfusion is recommended, while in case with severe anemia and cardiac failure an exchange transfusion can be considered. The physician’s awareness of the condition, the ability to suspect and diagnose it with appropriate testing have a significant impact on the epidemiology, accurate management and prognosis for the anemic neonates.
