Postextubation Noninvasive Ventilation in Respiratory Distress Syndrome: A Randomized Controlled Trial.

OBJECTIVE: Successful extubation and prevention of reintubation remain primary goals in neonatal ventilation. Our aim was to compare three modalities of postextubation respiratory support-noninvasive positive pressure ventilation (NIPPV), nasal bilevel positive airway pressure (N-BiPAP), and nasal continuous positive airway pressure (NCPAP)-using the RAM cannula in preterm neonates with respiratory distress syndrome (RDS). Our secondary aim was to define the predictors of successful extubation. STUDY DESIGN: A total of 120 preterm neonates (gestational age ≤35 weeks) with RDS who had undergone primary invasive ventilation were randomized to receive either NIPPV, N-BiPAP, or NCPAP. The incidence of respiratory failure in the first 48 hours postextubation, total days of invasive and noninvasive ventilation, duration of hospitalization, and mortality were measured and compared among the three different noninvasive support modalities. RESULTS: There were no significant differences in the postextubation respiratory failure rates and the number of days of invasive as well as noninvasive ventilation among the three different support modalities (p > 0.05). The total number of days of mechanical ventilation and the duration of hospitalization were significantly higher in the N-BiPAP group than those in the NCPAP or NIPPV groups (p < 0.05). A gestational age of at least 29 weeks and a birth weight of at least 1.4 kg were predictive of successful extubation with a sensitivity of 98.2 and 85.3% and a specificity of 63.6 and 90.9%, respectively. CONCLUSION: Longer durations of mechanical ventilation and hospitalization were observed with N-BiPAP as a noninvasive mode of ventilation, but there was no significant difference in the extubation failure rates among the three modalities. Gestational age and birth weight were shown to be independent predictors of successful extubation of preterm neonates with RDS. KEY POINTS: · Successful extubation and reintubation prevention of preterms are primary goals in neonatal ventilation.. · NIPPV, N-BiPAP, and NCPAP could be used as postextubation noninvasive modes in preterm neonates.. · Gestational age and birth weight are independent predictors of successful extubation of preterms..

Kawasaki disease and the pediatric gastroenterologist: a diagnostic challenge.

BACKGROUND AND OBJECTIVES: Gastrointestinal symptoms and signs are rarely the main clinical presentation of Kawasaki disease (KD). In the present study, we report a series of patients with KD in whom a gastroenterology consult was obtained before consideration of the diagnosis of KD. METHODS: We retrospectively reviewed all patients with KD admitted to Children's Hospital Colorado from January 2009 through February 2011 with prominent gastrointestinal symptoms, resulting in gastrointestinal service consultation before their diagnosis of KD. RESULTS: We identified 7 of 118 (6%) patients with KD who met our criteria. All 7 patients were males, and the median age at admission was 9.7 years. All patients had abdominal pain and fever at presentation. Vomiting, diarrhea, and clinical jaundice were present in 70%, 50%, and 43% of patients, respectively. Aminotransferases and/or γ-glutamyl transpeptidase abnormalities were observed in 6 (89%) patients. All of the patients had fever and rash on admission, and 86% had nonexudative conjunctivitis and 71% had mucosal changes. Median duration of illness at gastroenterology consultation was 5 days, whereas median duration of illness at infectious disease consultation was 6 days. One patient developed coronary artery dilation and 2 patients had intravenous immunoglobulin-resistant KD. CONCLUSIONS: Gastroenterologists should be aware of gastrointestinal presentations of KD. Unexplained gastrointestinal symptoms in the presence of fever, and 1 or 2 of the major clinical signs of KD, should prompt consideration of KD in the differential diagnosis.

Abnormal liver panel in acute kawasaki disease.

BACKGROUND AND AIMS: abnormalities of liver panel (liver function test [LFT]) are frequently documented in patients with Kawasaki disease (KD). We sought to define the spectrum of abnormalities in liver panel tests in children with KD. We studied the characteristics of KD patients who presented with an abnormal liver panel and their response to treatment. METHODS: we retrospectively reviewed the medical records of all KD patients admitted between 2004 and 2009 with one or more LFTs done at presentation and compared patients with and without at least 1 abnormal liver panel test including alanine aminotransferase, aspartate aminotransferase, gamma glutamyl transferase, and bilirubin. These patients were divided into 2 groups: those with normal LFTs (normal LFT group) and those with at least one abnormal LFT at presentation (abnormal LFT group). RESULTS: Of 259 patients, 240 (92.7%) patients with KD reviewed had one or more LFTs performed. One hundred nine (45.4%) had at least 1 abnormal liver panel test. Patients in the abnormal LFT group presented earlier (P = 0.01) and were more likely to have intravenous immunoglobulin (IVIG) resistant disease (P = 0.01). There was no significant difference between groups in development of coronary artery abnormalities or aneurysms. Multivariate analysis identified C-reactive protein and total bilirubin at admission as significant predictors for IVIG resistant disease. CONCLUSION: we report the largest US single center study of the spectrum of liver panel abnormalities in children with acute KD. Abnormalities of LFTs are frequently found in patients with acute KD and children with abnormal LFTs were at higher risk for IVIG resistance.
