Outcomes analysis in congenital diaphragmatic hernia (CDH) requires a validated risk-adjustment tool. The purpose of this study was to use the Canadian Neonatal Network (CNN) database to validate the Score for Neonatal Acute Physiology, Version II (SNAP-II) for prediction of mortality among CDH infants admitted to a neonatal intensive care unit (NICU), and to compare this to the predictive equation recently developed by the Congenital Diaphragmatic Hernia Study Group (CDHSG). ⋯ SNAP-II is highly predictive of mortality among patients with CDH, and can be used to risk-adjust these patients.

Successful management of neonatal shock is driven by the etiology and pathophysiology of the cardiovascular compromise. In the clinical practice, however, we only have a limited ability to recognize the etiology of the condition (hypovolemia, myocardial dysfunction or abnormal vasoregulation). ⋯ In addition, although management strategies aimed at improving systemic blood pressure may have been associated with a decrease in mortality in critically ill neonates, there are no prospective data on the effect of these management strategies on morbidity, especially on long-term neurodevelopmental outcome. This paper briefly reviews some of the more frequently encountered clinical presentations of neonatal shock and describes the developmentally regulated cardiovascular responses to the pathophysiology-driven management strategies used in these clinical presentations in the critically ill preterm and term neonate.

Dedicated neonatal retrieval teams improve delivery room resuscitation of outborn premature infants.
Morbidity related to ineffective resuscitation and stabilization of premature infants is increased when delivery occurs outside tertiary perinatal centers. The regional neonatal transport team received extensive training to expand their scope of practice to include delivery room resuscitation allowing them to attend high-risk deliveries in community hospitals when maternal transfer was not possible. ⋯ The presence of a highly skilled transport team at a high-risk preterm delivery improves the quality of neonatal resuscitation by increasing intubation success rates and achieving earlier vascular access. Neonates resuscitated by dedicated neonatal retrieval teams were less likely to become significantly hypothermic. Although the severity of RDS was similar neonates in the RHT were less likely to receive surfactant.

Our primary objective was to examine the relationship between umbilical arterial gas analysis and decision-to-delivery interval for emergency cesareans performed for nonreassuring fetal status to determine if this would validate the 30-minute rule. ⋯ Electronic fetal monitoring shows considerable variation in interpretation among maternal-fetal medicine specialists and is not a sensitive predictor of the fetus developing metabolic acidosis. There is no deterioration in cord gas results after 30 minutes, and most neonates delivered emergently or urgently for nonreassuring fetal status even when born after 30 minutes have normal cord gases. The 30-minute rule is a compromise that reflects the time it takes the fetus to develop severe metabolic acidosis, our imprecision in its identification, and its rarity in the presence of nonreassuring fetal monitoring.

The most common admission to intensive care nurseries is the infant with suspected neonatal sepsis. To determine the clinical practice of neonatologists with respect to this diagnosis, we examined a large neonatal database during a 2-year period of time. The goal of this study was to define whether there were optimal practice strategies that could identify a "benchmark" clinical approach for this diagnosis. ⋯ Treatment of neonates with suspected sepsis appears to be influenced by considerations other than maternal risk factors or the infant's clinical condition beyond the first day of life. There appears to be a great deal of practice variation among neonatologists confronted by patients with suspected sepsis. Awareness of this unnecessary variation may be of great value in reducing the duration of antibiotic therapy in the NICU and shortening the length of stay.
