Chronic respiratory morbidity is a common adverse outcome of preterm birth, especially in infants who develop bronchopulmonary dysplasia (BPD), which is still a major cause of long-term lung dysfunction with a heavy burden on health care services and medical resources throughout childhood. The most severely affected patients remain symptomatic even in adulthood, and this may be influenced also by environmental variables (e.g. smoking), which can contribute to persistent obstruction of airflow. ⋯ Since the prevention of BPD is an elusive goal, minimizing neonatal lung injury and closely monitoring survivors remain the best courses of action. This review describes the clinical and functional changes characteristic of the long-term pulmonary sequelae of preterm birth, focusing particularly on BPD.

Non-invasive cardiac output monitoring in preterm infants undergoing patent ductus arteriosus ligation: a comparison with echocardiography.
Non-invasive cardiac output monitoring (NICOM; NICOM™) may be useful in the management of extremely premature preterm infants. ⋯ Continuous LVO measurement using NICOM was feasible and demonstrated a consistent systematic bias compared with echocardiography in unstable extremely preterm infants without a PDA ligation. NICOM may be used as a trending tool for continuous monitoring in this population, but wide limits of agreement and increasing bias over time suggest it is not interchangeable with echocardiography. © 2014 S.

Caffeine, a methylxanthine and nonspecific inhibitor of adenosine receptors, is an example of a drug that has been in use for more than 40 years. It is one of the most commonly prescribed drugs in neonatal medicine. However, until 2006, it had only a few relatively small and short-term studies supporting its use. ⋯ The most frequent indication for therapy reported in CAP was treatment of documented apnea, followed by the facilitation of the removal of an endotracheal tube. Only about 20% of the neonatologists in the trial started caffeine for the prevention of apnea and the findings of CAP cannot automatically be extrapolated to an exclusive prophylactic indication. However, recent data suggest that the administration of prophylactic methylxanthine by neonatologists is now common practice.

Lung ultrasound (LUS) is a promising technique for the diagnosis of neonatal respiratory diseases. Preliminary data has shown a good sensitivity and specificity of LUS in the diagnosis of respiratory distress syndrome (RDS) and transient tachypnea of the newborn (TTN). ⋯ LUS showed high sensitivity and specificity in diagnosing RDS and TTN.

To study whether new pharmacological and nonpharmacological guidelines lowered numbers of painful procedures in neonates and changed the amount and frequency of analgesic therapy as compared to the results of our previous study in 2001. ⋯ The mean number of painful procedures per NICU patient per day declined. Nonpharmacological pain- or stress-reducing strategies like NIDCAP and sucrose were fully embedded in our pain management. As further reduction of the number of painful procedures is unlikely, we should apply more nonpharmacological interventions and explore newer pharmacological agents.
