The prevalence of obesity in developed countries is rising. Currently, Europe has a prevalence of 9-30% with significant impact on public health systems. Obese patients in ICUs require special management and treatment. Altered anatomy in obese patients complicates procedures such as mechanical ventilation. Obesity affects cardiopulmonary physiology and requires elevated ventilation pressures. In our retrospective study, we determined the effect of early percutaneous dilatational tracheotomy (PDT) and cessation of sedation on respiratory parameters in severely obese subjects. ⋯ In severe obesity, respiratory failure might be increased by problems in mechanical ventilation due to required high pressures and obesity-induced pulmonary restriction. Rapid tracheotomy with reduction of dead-space ventilation and airway resistance as well as cessation of sedation to enable spontaneous breathing might be a key factor in the therapy of respiratory failure.

Review Meta Analysis
Diagnostic Yield and Safety of Cryoprobe Transbronchial Lung Biopsy in Diffuse Parenchymal Lung Diseases: Systematic Review and Meta-Analysis.
Transbronchial lung biopsy with flexible forceps is the most commonly used technique in diagnosis of diseases diffusely involving the lung parenchyma. Recently, transbronchial lung biopsy using the flexible cryoprobe (cryo-transbronchial lung biopsy) has also been reported. Herein, we perform a systematic review and meta-analysis describing the efficacy and safety of cryo-transbronchial lung biopsy. ⋯ Cryo-transbronchial lung biopsy is a relatively safe procedure with good diagnostic yield in diseases diffusely involving the lung parenchyma.

Ribavirin is an antiviral drug that can be administered by inhalation. Despite advancements in the oral delivery of this medication, there has been a renewed interested in delivering ribavirin via the pulmonary system. Although data are not conclusive that inhaled ribavirin improves outcomes, we set out to determine whether delivery by a newer generation nebulizer, the vibrating mesh micropump, was as effective as the recommended small-particle aerosol generator system. ⋯ The vibrating mesh micropump nebulizer may provide an effective alternative to the small-particle aerosol generator in administration of ribavirin using NaCl or sterile water, both on and off the ventilator. Further clinical studies are needed to compare efficacy.
