Bladder Temperature During Neonatal Targeted Temperature Management: A Case Report.

BACKGROUND: Neonatal encephalopathy is a clinical condition of altered neurological function in the first days of life. Targeted temperature management (TTM) is a validated approach to mitigate neurologic sequelae. Current literature suggests using rectal or esophageal site to assess temperature during TTM, but few studies focused on the best and the less invasive site to evaluate the temperature. This case report describes the performance of the bladder temperature monitoring during TTM. CLINICAL FINDINGS: A female newborn was born at 39 weeks' gestational age plus 4 days. At delivery, the newborn was in cardiorespiratory arrest. PRIMARY DIAGNOSIS: After performing cardiopulmonary resuscitation and neurological examination, a hypoxic-ischemic encephalopathy was diagnosed. INTERVENTIONS: After about 2 hours from birth, the newborn underwent TTM. OUTCOMES: A total of 4642 measurements of rectal temperature and 4520 measurements of bladder temperature were collected. Agreement between the 2 sites was statistically significant with a mean difference of 0.064°C ± 0.219 (95% confidence interval, -0.364 to 0.494); F = 47.044; and P value of less than .001. Furthermore, difference between rectal and bladder sites was not influenced by patient's urine output ( F = 0.092, P = .762). PRACTICE RECOMMENDATIONS: Bladder temperature seems to have a good reliability and not to be inferior to the other assessment site currently used. Using bladder catheter with temperature sensor could reduce the number of devices, ensure safer stabilization, and decrease treatment downtime.

Severe Hypercapnia Requiring 48-h Whole-Body Hypothermia in an Infant with Acute Bronchiolitis.

Bronchiolitis is a clinical syndrome involving the lower respiratory tract of infants and young children. The majority of patients recover using adequate hydration and oxygen (O2) therapy, while a small number of patients require ventilatory assistance. Beyond these therapeutical approaches, there are no available strategies for patients that do not improve. Hypothermia is a measure used to prevent neonatal hypoxic-ischemic encephalopathy by preventing carbon dioxide (CO2) production and subsequent tissue damage. Other medical applications of hypothermia have been proposed, such as in acute respiratory failure and necrotizing colitis. Case report: We report the case of a 50-day-old girl hospitalized with severe bronchiolitis caused by respiratory syncytial virus. On admission, the girl presented severe hypercapnic respiratory failure, requiring intubation and ventilatory support with conventional and non-conventional systems. However, the patient's general conditions worsened with elevated O2 demand, thus whole-body hypothermia was attempted and performed for 48 h, with a gradual improvement in the respiratory function. No adverse effects were detected. Conclusions: Whole-body hypothermia could have a critical role as a rescue treatment in infants affected by severe hypercapnic respiratory failure, at the expense of few and rare side effects (bradycardia, coagulopathy, hyperglycemia). Notably, beyond reducing CO2 production, whole-body hypothermia might have an impact in restoring lung function in newborns using bronchiolitis refractory to maximal medical therapy and invasive ventilation.

Infant-Directed Speech From a Multidimensional Perspective: The Interplay of Infant Birth Status, Maternal Parenting Stress, and Dyadic Co-regulation on Infant-Directed Speech Linguistic and Pragmatic Features.

Infant-directed speech (IDS), the particular form of spontaneous language observed in interactions between parents and their infants, is a crucial aspect of the mother-infant interaction and an index of the attunement of maternal linguistic input to her infant communicative abilities and needs during dyadic interactions. The present study aimed to explore linguistic and pragmatic features of IDS during mother-infant interactions at 3-month of infant age. The effects of infant (birth status: preterm vs. full-term birth), maternal (perceived parenting stress) and dyadic (dyadic co-regulation) factors on IDS were explored. Results evidenced few differences between the groups on IDS linguistic characteristics. Moreover, observing the interaction of birth status and dyadic co-regulation, full-term mothers varied their IDS pragmatic features according to the quality of co-regulation while preterm mothers did not. Parenting stress was associated to specific linguistic IDS features independently from the birth status. Findings are discussed underling implications for the study of preterm dyads interactions and the importance to consider the interplay of several factors in affecting the quality of IDS.

Successful lung response after surgical repair in an infant with right-sided congenital diaphragmatic hernia.

Congenital diaphragmatic hernia is a rare condition associated with pulmonary complications as the abdominal viscera herniated into the chest may affect lungs development. We present the case of a male newborn baby with a prenatal diagnosis of a posterolateral defect (Bochdalek hernia) involving the right side. The infant underwent surgical repair at 3 days of life, and the post-surgery chest X-ray did not reveal morpho-structural alterations of the lungs and diaphragmatic profile. Our clinical case shows that patients may have a better lung outcome despite an initial unfavorable picture. Prenatal diagnosis is essential in identifying infants with congenital diaphragmatic hernia, especially those cases at higher risk for the worse outcomes, to optimize their clinical and surgical management.
