Vasopressin is emerging as a therapeutic adjunct option towards treatment of shock states in the pediatric population. Its effects on pulmonary vasculature are less well understood. This report describes a 5-month-old infant with nitric oxide-unresponsive pulmonary hypertension, oxygenation failure, and systemic hypotension. Vasopressin therapy improved oxygenation and blood pressure and biventricular function, allowing weaning of nitric oxide and inotropic support. No decrease in coronary flow was noted. ⋯ Vasopressin could be considered as an adjunct option in infants with pulmonary hypertension and systemic hypotension. Echocardiographic monitoring during treatment is recommended.

Wolcott-Rallison syndrome has been reported to be associated with early-onset diabetes, epiphyseal dysplasia, hepatic and renal dysfunction, mental retardation, severe growth retardation, neutropenia, exocrine pancreatic dysfunction, and central hypothyroidism. We report on primary hypothyroidism, which has not been previously described, of a patient with Wolcott-Rallison syndrome due to novel mutation (W521X), who showed improved growth after thyroid hormone treatment.

Mutations in the gene for adenosine triphosphate-binding cassette transporter subfamily A member 3 (ABCA3) have been reported in infants and children with surfactant deficiency and interstitial lung disease. We report a case of siblings found to be compound heterozygotes for two novel ABCA3 gene mutations but developing very different course of lung disease. ⋯ Our findings suggest the contribution of other genetic, epigenetic and environmental factors to discordant phenotype observed in patients carrying the same mutations in the ABCA3 gene. The clinical course of the index case suggests benefit of combined medical therapy in treating infants with ABCA3 deficiency.

The treatment of neonatal limb ischemia (LI) is challenging for neonatologists. Peripheral nerve blockade (PNB), alone or in association with other therapies, represents a valid therapy in case of vascular spasm or thromboembolic events responsible for LI. ⋯ PNB was not performed according to the traditional technique but rather by a peridural catheter left in situ for 9 days with a continuous infusion of ropivacaine. In conclusion, the effectiveness of this approach was confirmed by the contemporary near-infrared spectroscopy monitoring, documenting gradual improvement of leg perfusion.

Randomized Controlled Trial
The influence of cardiopulmonary bypass priming without FFP on postoperative coagulation and recovery in pediatric patients with cyanotic congenital heart disease.
Transfusion guidelines have been produced for the evidence-based use of fresh frozen plasma (FFP). However, the inappropriate use of FFP is still a worldwide problem, especially in the prophylactic settings. In the present study, 100 cyanotic pediatric patients (age 6 months to 3 years) undergoing cardiac surgery with cardiopulmonary bypass (CPB) were randomized to receive either 10-20 ml/kg FFP (FFP group, n = 50) or 10-20 ml/kg 4 % succinylated gelatin (Gelofusine, GEL group, n = 50) in the priming solution. Rapid thromboelastography (r-TEG) was measured before skin incision and 15 min after heparin neutralization. Postoperative renal and hepatic function, mediastinal chest tube drainage, transfusion requirements, and recovery time were observed. The relationships between hematologic and demographic data and postoperative bleeding volume were also analyzed. The results showed that there were significantly elevated levels of fibrinogen (r-TEG parameters: fibrinogen contribution to maximal amplitude (MAf) and fibrinogen level (FLEV)) in the FFP group compared to the GEL group. The postoperative blood loss, total transfusion requirements, and recovery time were not significantly different between the two groups, indicating that there were no obvious clinical benefits of using FFP in the priming. The maximal amplitude (MA) of r-TEG measured after heparin neutralization was correlated with the 6-h postoperative bleeding volume. In addition, preoperative fibrinogen level rather than FFP priming was an independent predictor of postoperative blood loss. ⋯ Prophylactic use of FFP in the priming solution does not have obvious clinical benefits in cyanotic congenital heart disease (CCHD) patients. Gelofusine, an artificial colloid, is a safe and effective substitute of FFP in the priming solution. Furthermore, r-TEG can be used as a "real-time" assessment tool to evaluate postoperative bleeding and guide transfusion after cardiac surgery in pediatric patients.
