Ultrasound-Guided Umbilical Venous Catheter Insertion With Alignment of the Umbilical Vein and Ductus Venosus.

Previous studies have highlighted the importance of confirming the position of an umbilical venous catheter (UVC) tip by an ultrasound (US) examination. However, methods for preventing insertion into the portal circulation under US guidance have not yet been established. We report 15 cases in which a UVC was successfully passed through the ductus venosus by compressing the upper abdomen near the portal sinus of the liver to align the umbilical vein and ductus venosus under US guidance. The UVC was inserted into the correct position in 14 of the 15 neonates (93%) without complications.

Blood pressure and aEEG in the 96h after birth and correlations with neurodevelopmental outcome in extremely preterm infants.

BACKGROUND: The management of hypotension immediately after the birth of preterm infants is controversial. AIM: To investigate the relationship between blood pressure (BP), amplitude-integrated electroencephalography (aEEG), and neurodevelopmental outcome in extremely preterm infants. METHODS: BP and aEEG were monitored for 96h after birth in 36 infants born at <27weeks gestation. aEEG data were analyzed with Burdjalov scores. Correlations of aEEG findings with BP and several clinical characteristics, including the Score for Neonatal Acute Physiology, Perinatal Extension-II (SNAPPE-II) were explored. A subgroup analysis of BP, aEEG activity, and neurodevelopmental outcome at 18-22months corrected age was also performed. Poor outcome was defined as death or a developmental quotient <70. RESULTS: Multiple regression analyses revealed no association between BP during the first 48h after birth and aEEG activity. However, BP 48-96h after birth was significantly associated with simultaneous aEEG activity (p<0.001). Within 48h after birth, SNAPPE-II was significantly associated with aEEG activity. Outcome was assessed in 32 infants; 24 and 8 of whom had good and poor outcomes, respectively. aEEG activity was significantly lower in neonates with a poor outcome than those with a good outcome (<0.001). No significant differences in outcome were observed for BP. CONCLUSION: The activity of aEEG was associated with illness severity during the first 48h after birth. After 48h, there was no effect of illness severity but there was an association with BP. We do not know if hypotension results in a poor outcome. However, aEEG activity was associated with neurodevelopmental outcome.

Temporal Relationship between Serum Levels of Interleukin-6 and C-Reactive Protein in Therapeutic Hypothermia for Neonatal Hypoxic-Ischemic Encephalopathy.

Objective C-reactive protein (CRP) is a useful marker of neonatal infection. Recent studies have shown that neonatal therapeutic hypothermia delays an elevation of CRP in infants with hypoxic-ischemic encephalopathy (HIE). This study investigated the time difference of peak levels of serum CRP and other inflammatory responses during therapeutic hypothermia. Study design We prospectively studied the serial serum data of CRP, interleukin-6 (IL-6), procalcitonin (PCT), and complete blood counts during the first week of life in HIE infants receiving therapeutic hypothermia. Results We identified 22 infants who received therapeutic hypothermia between August 2013 and July 2015. No infants developed clinically overt infections. The peak of serum levels of IL-6, PCT, and CRP were postnatal days 1, 2, and 4, respectively. White blood cells, neutrophils, and platelet counts gradually decreased from days 1 to 7. Early postnatal serum levels of IL-6 correlated with CRP on day 4 (IL-6 on day 2; r = 0.78, p < 0.001). Conclusion The peak value of CRP on day 4 might reflect the early production and secretion of IL-6 rather than an actual infection. Serial measurement of IL-6 might help avoid invasive sepsis workup and unnecessary change of antibiotics in infants.

Effectiveness of Corticosteroid Therapy for Acute Neurological Symptoms in Incontinentia Pigmenti.

BACKGROUND: Incontinentia pigmenti is a rare neurocutaneous disorder that may result in neurological symptoms in addition to its characteristic skin rashes. The pathogenesis of central nervous system disorders in incontinentia pigmenti remains unclear, but it has been suggested that vascular abnormalities and inflammatory processes may play important roles. Notably, there is no established treatment for central nervous system disorders in incontinentia pigmenti. We report a neonate with acute neurological symptoms of incontinentia pigmenti who was effectively treated with corticosteroid therapy. We review the literature and discuss the pathophysiology, diagnosis, and treatment of acute central nervous system disorders in incontinentia pigmenti. PATIENT DESCRIPTION: A 15-day-old girl with incontinentia pigmenti experienced neurological symptoms such as decreased level of consciousness and a weak sucking reflex. Magnetic resonance imaging revealed multiple cerebral infarctions. We administered corticosteroid therapy, and the symptoms improved immediately and significantly. CONCLUSION: We suggest that corticosteroid therapy may be an effective treatment during the acute phase of central nervous system dysfunction due to incontinentia pigmenti. It is important to determine the existence of acute phase lesions on magnetic resonance imaging when neurological symptoms occur or worsen.
