The Respiratory Management of the Extreme Preterm in the Delivery Room.

The fetal-to-neonatal transition poses an extraordinary challenge for extremely low birth weight (ELBW) infants, and postnatal stabilization in the delivery room (DR) remains challenging. The initiation of air respiration and the establishment of a functional residual capacity are essential and often require ventilatory support and oxygen supplementation. In recent years, there has been a tendency towards the soft-landing strategy and, subsequently, non-invasive positive pressure ventilation has been generally recommended by international guidelines as the first option for stabilizing ELBW in the delivery room.

[Effect of adding fortifiers and protein supplements on the osmolality of donated maternal milk].

Introduction And Objectives: The fortification of maternal milk (MM) is a standard practice in order to achieve the requirements needed for the growth and development of the premature newborn. However, its osmolality could increase. According to the American Paediatrics Academy, it is recommended not to exceed 450 mOsm/kg (approximately 400 mOsm/L) in the diet of the infant, even though the safety limit is estimated to be between 400 and 600 mOsm/kg.

[Myoadenylate deaminase deficiency in a child with myalgias induced by physical exercise].

Introduction: Myoadenylate deaminase deficiency (MAD) constitutes the most common genetically determined enzymatic defect of the skeletal muscle (2% of the population), however, it causes clinical symptoms such us exercise-related muscle cramps and pain in quite a lower number of patients, being exceptional in children.

Case Report: A 7 year old boy is referred with intense myalgias after physical exertion associating increased creatin kinase level 3,273 UI/L (normal 24-195) which goes down in rest period to increase again with myalgias during exercise. The ischemic forearm exercise test shows a flat ammonia curve with a normal lactate rise in relation to control.

[Nasal continuous positive airway pressure in preterm infants: comparison of two low-resistance models].

Objective: To compare the safety and efficacy of two low expiratory resistance models of nasal continuous positive airway pressure (n-CPAP) in preterm infants.

Material And Methods: A 1-year prospective trial was performed in the Neonatal Intensive Care Unit of La Fe Hospital to compare the Infant Flow (IF) and Medijet (MJ) devices. All preterm infants requiring n-CPAP for respiratory distress at birth (group I), infants weighting less than 1500 g requiring postextubation (group II) and those with apnea-bradycardia syndrome (ABS) (group III) were included.
