Cystic fibrosis (CF) is a multiorgan, genetic disease resulting from dysfunction of the CF transmembrane conductance regulator. The primary clinical manifestations are bronchiectasis, chronic pulmonary infections with recurrent exacerbations, and pancreatic insufficiency. Advances in CF care have led to improved survival, with more than one-half of those affected being adults. ⋯ Multiple aspects of the care of patients with CF benefit from specialized knowledge, including pancreatic enzyme replacement and nutritional support; airway clearance modalities; treatment of multiply resistant, polymicrobial infections, and unique drug metabolism. In extreme cases, patients may benefit from advanced therapies, including extracorporeal support and organ transplant. Optimal care of patients with CF requires a multidisciplinary care team that includes respiratory therapists, dieticians, social workers, psychologists, pharmacists, and physicians who have expertise in the treatment of this complex, multisystem disorder.

Randomized Controlled Trial
Lung ultrasound score-based perioperative assessment of pressure-controlled ventilation-volume guaranteed or volume-controlled ventilation in geriatrics: a prospective randomized controlled trial.
Recent studies have shown the potential benefits of pressure-controlled ventilation-volume guaranteed (PCV-VG) compared to volume-controlled ventilation (VCV), but the results were not impressive. We assessed the effects of PCV-VG versus VCV in elderly patients by using lung ultrasound score (LUS). ⋯ This study was registered at the UMIN clinical trials registry (unique trial number: UMIN000029355; registration number: R000033510).

A clinical study on mechanical ventilation PEEP setting for traumatic ARDS patients guided by esophageal pressure.
This study aims to explore whether positive end-expiratory pressure (PEEP) guided by esophageal pressure is better than the acute respiratory distress syndrome network (ARDSNet) during the treatment of traumatic acute respiratory distress syndrome (ARDS) patients. ⋯ The PEEP selection of mechanical ventilation of patients with traumatic ARDS guided by transpulmonary pressure and calculated by measuring intrapleural pressure can realize the individual adjustment of PEEP, identify ARDS patients benefiting from high PEEP, and provide a PEEP setting that can better meet the needs of traumatic patients.

In recent years, low-dose, short-acting anesthetic agents, which replaced the former high-dose opioid regimens, offer a faster postoperative recovery and decrease the need for mechanical ventilatory support. In this study, the aim was to determine the success rate of fast-track approach in surgical procedures for congenital heart disease. There is some evidence, mostly from retrospective analyses, that fast tracking can be beneficial. ⋯ In this setting a carefull choice and dosing of anesthetic agents, alongside a good postoperative analgesia are mandatory. The authors found that an early extubation (< 4 hours) can be both effective and safe as it reduces intubation and ventilator times without increasing post-operative complications in pediatric congenital heart disease. This study supports a wider use of fast-track extubation protocols in paediatric patients submitted for congenital cardiac surgery in developing countries.

The Effects of Positive End-Expiratory Pressure on Transpulmonary Pressure and Recruitment-Derecruitment During Neurally Adjusted Ventilator Assist: A Continuous Computed Tomography Study in an Animal Model of Acute Respiratory Distress Syndrome.
Whether spontaneous breathing (SB) should be used in early acute respiratory distress syndrome (ARDS) is questioned because it may cause ventilator-induced lung injury (VILI) by tidal high strain/stress and recruitment/derecruitment (R/D). However, SB has shown beneficial effects when used appropriately. We hypothesized that high levels of positive end-expiratory pressure (PEEP), during assisted SB, would prevent tidal R/D, reducing ventilatory variation and respiratory rate while potentially increasing transpulmonary pressure (P TP). The aim was to test this hypothesis in experimental mild ARDS during continuous SB using neurally adjusted ventilator assist (NAVA) and uninterrupted computed tomography (CT) exposure. ⋯ This study shows that injurious phenomena like R/D and high P TP are present in NAVA at the two extremes of the PEEP spectrum. Willing to titrate PEEP to limit these phenomena, the physician must choose the best compromise between restraining the R/D or P TP.
