Therapeutic hypothermia (THT) is the recommended treatment for neuroprotection in (near) term newborns that experience perinatal asphyxia with hypoxic-ischemic encephalopathy. The benefit of THT in preterm newborns is unknown. This pilot study aims to investigate long-term outcomes of late preterm asphyctic infants with and without THT compared to term infants. The single-center, retrospective analysis examined medical charts of infants with perinatal asphyxia born between 2008 and 2015. Long-term outcome was assessed using the Bayley Scales of Infant Development 2 at the age of (corrected) 24 months. Term (n = 31) and preterm (n = 8) infants with THT showed no differences regarding their long-term outcomes of psychomotor development (Psychomotor Developmental Index 101 ± 16 vs. 105 ± 11, p = 0.570), whereas preterm infants had a better mental outcome (Mental Developmental Index 105 ± 13 vs. 93 ± 18, p = 0.048). Preterm infants with and without (n = 69) THT showed a similar mental and psychomotor development (Mental Developmental Index 105 ± 13 vs. 96 ± 20, p = 0.527; Psychomotor Developmental Index 105 ± 11 vs. 105 ± 15, p = 0.927). The study highlights the importance of studying THT in asphyctic preterm infants. However, this study shows limitations and should not be used as a basis for decision-making in the clinical context. Results of a multicenter trial of THT for preterm infants (ID No.: CN-01540535) have to be awaited.

Abstract There is no consensus on the optimal pCO2 levels in the newborn. We reviewed the effects of hypercapnia and hypocapnia and existing carbon dioxide thresholds in neonates. A systematic review was conducted in accordance with the PRISMA statement and MOOSE guidelines. Two hundred and ninety-nine studies were screened and 37 studies included. Covidence online software was employed to streamline relevant articles. Hypocapnia was associated with predominantly neurological side effects while hypercapnia was linked with neurological, respiratory and gastrointestinal outcomes and Retinpathy of prematurity (ROP). Permissive hypercapnia did not decrease periventricular leukomalacia (PVL), ROP, hydrocephalus or air leaks. As safe pCO2 ranges were not explicitly concluded in the studies chosen, it was indirectly extrapolated with reference to pCO2 levels that were found to increase the risk of neonatal disease. Although PaCO2 ranges were reported from 2.6 to 8.7 kPa (19.5–64.3 mmHg) in both term and preterm infants, there are little data on the safety of these ranges. For permissive hypercapnia, parameters described for bronchopulmonary dysplasia (BPD; PaCO2 6.0–7.3 kPa: 45.0–54.8 mmHg) and congenital diaphragmatic hernia (CDH; PaCO2 ≤ 8.7 kPa: ≤65.3 mmHg) were identified. Contradictory findings on the effectiveness of permissive hypercapnia highlight the need for further data on appropriate CO2 parameters and correlation with outcomes. Impact There is no consensus on the optimal pCO2 levels in the newborn. There is no consensus on the effectiveness of permissive hypercapnia in neonates. A safe range of pCO2 of 5–7 kPa was inferred following systematic review.

Abstract BACKGROUND The optimal mode of delivery for preterm infants remains controversial, and routine Caesarean sections (C/S) are not recommended, except for maternal indications. Nonetheless, many preterm infants are delivered by C/S, particularly those in breech presentation, and recent retrospective data have suggested that these infants may have improved outcomes. OBJECTIVES To examine whether C/S as the mode of preterm delivery is associated with decreased mortality and improved short term outcomes. DESIGN/METHODS This retrospective, population-based cohort study examined infants with a gestational age between 23 0/7 weeks and 32 6/7 weeks, born between January 1, 2007 and December 31, 2016, and admitted to the Neonatal Intensive Care Unit at a single Canadian Tertiary Care hospital. Infants with major congenital anomalies were excluded. Data were abstracted from the local Neonatal-Perinatal database for all infants. Two groups, those delivered vaginally and those delivered by C/S, were compared for major neonatal outcomes including the primary outcomes of death and severe intraventricular hemorrhage (IVH), defined as grade 3 or higher. RESULTS A total of 1442 infants met inclusion criteria (784 born by C/S and 658 vaginally). There was no significant difference in neonatal mortality (7.0% vs 7.1%, p=0.925) or severe IVH (6.1% vs 7.4%, p=0.317). There was, however, a significant difference in the incidence of IVH, any grade (19.9% vs 27.5%, p=0.001), which remained after controlling for other significant predictors. There were no other significant differences in the secondary outcomes examined including need for extensive resuscitation, respiratory distress syndrome, bronchopulmonary dysplasia, patent ductus arteriosus, necrotizing enterocolitis, periventricular leukomalacia, or retinopathy of prematurity. CONCLUSION Caesarean section was not associated with decreased mortality in preterm infants, relative to vaginal births. Caesarean section was associated with a reduced rate of IVH (any grade) and there was a trend towards decreased severe IVH which may warrant further study.
