Randomized Controlled TrialThe effects of nasal continuous positive airway pressure and high flow nasal cannula on heart rate variability in extremely preterm infants after extubation: A randomized crossover trial.
NCPAP and High flow nasal cannula (HFNC) are common modes of non-invasive respiratory support used after extubation. Heart rate variability (HRV) has been demonstrated as a marker of well-being in neonates and differences in HRV were described in preterm infants receiving respiratory care. The objective was to investigate the effects of NCPAP and HFNC on HRV after extubation. ⋯ During the first hours after extubation, no differences in HRV were detected between HFNC and NCPAP in the overall cohort. However, a significantly higher HRV was noted during HFNC in the subgroup of infants successfully extubated.

Multicenter Study Observational StudyLung ultrasound for prediction of respiratory support in infants with acute bronchiolitis: A cohort study.
Respiratory tract infections are among the most common causes of morbidity and mortality worldwide. Acute bronchiolitis (AB) is the leading cause of hospital admission among infants. Clinical scores have proven to be inaccurate in predicting prognosis. Our aim was to build a score based on findings of lung ultrasound (LU) performed at admission, to stratify patients at risk of needing respiratory support (non-invasive and invasive ventilation). ⋯ A total of 145 patients were included in the study, with a median age of 1.7 months [IQR: 1.2-2.8], 47.6% were female. Mean duration of symptoms prior to admission was 3.1 days (SD 1.8). Fifty-six patients (39%) required non-invasive ventilation (NIV), 14 (9.7%) were transferred to PICU, and 3 needed invasive ventilation (3/145). Identification of at least one posterior consolidation >1 cm was the main factor associated to NIV (RR 4.4; [CI95%1.8-10.8]) The LU score built according to the findings on admission showed an AUC: 0.845(CI95%:0.78-0.91). A score ≥3.5 showed a sensitivity of 89.1% (CI95%:78.2-94.9%) and specificity of 56% (CI95%: 45.3-66.1%) CONCLUSIONS: Among infants below 6 months of age admitted with AB, point-of-care LU was a helpful tool to identify patients at risk of needing respiratory support.

Utility and safety of endobronchial ultrasound-guided transbronchial needle aspiration and endoscopic ultrasound with an echobronchoscope-guided fine needle aspiration in children with mediastinal pathology.
Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and endoscopic ultrasound with an echobronchoscope-guided fine needle aspiration (EUS-B-FNA) are useful modalities in the evaluation of mediastinal pathologies in adults. However, sparse data are available in children. ⋯ EBUS-TBNA and EUS-B-FNA are helpful in children with undiagnosed mediastinal pathology with fair diagnostic yield and excellent patient safety profile.

The outlook for people with cystic fibrosis (CF) has improved considerably as a result of conventional therapies including aerosolized agents for airway clearance. These will continue to play a significant role in maintaining well-being and improving survival, even as newer agents emerge that correct the underlying CF defect. ⋯ We also discuss the clinical use of these agents in the context of available international guidelines as well as practical considerations in the clinic, highlighting the importance of a multidisciplinary approach and shared decision-making. Unanswered questions regarding the optimal use of these agents are highlighted.

Decrease the flow setting to improve trans-nasal pulmonary aerosol delivery via "high-flow nasal cannula" to infants and toddlers.
Trans-nasal pulmonary aerosol delivery for infants and toddlers has recently gained popularity, however, the reported lung deposition is low. We aimed to investigate the influential factors to improve the delivery. ⋯ Trans-nasal pulmonary aerosol delivery was significantly improved when gas flow was below patient's inspiratory flow, aerosol deposition increased with decreased nasal cannula flow, with greatest deposition at 0.25 L/kg/min.
