Nineteen fiberoptic bronchoscopic procedures were performed on ten patients for the treatment of pulmonary collapse. All but two patients were being treated for severe, life-threatening nonpulmonary diseases. Thick, tenacious, and, at times, purulent mucous plugs were successfully aspirated from the bronchial passages. Complete to partial radiologic reexpansion of the collapsed pulmonary region was observed following all but one procedure. Significant improvement in blood gas levels was also noticed immediately after the procedure. Bronchoscopic examination in these seriously ill patients did not cause any complications. The therapeutic value of fiberoptic bronchoscopic procedures in patients developing pulmonary collapse due to thick secretions and mucous plugs was demonstrated.

Background: Extracorporeal membrane oxygenation (ECMO) can act as a bridge to recovery in both pre-and postoperative patients with transposition of the great arteries (TGA). However, literature on its use in these patients is scarce.
Methods: Retrospective single-centre cohort study encompassing all TGA patients who received ECMO between January 2009 and March 2024.

Background Lung resection is a complex surgical procedure performed in children to address various pulmonary conditions. The success of this surgical intervention in these patients lies in a multidisciplinary approach, with anesthetic management playing a critical role in ensuring the safety and efficacy of the procedure. Methods After approval by the local ethics committee, clinical data of 17 pediatric patients who underwent lung resection in our hospital from January 2012 to December 2022 were retrospectively analyzed.

Early and accurate diagnosis of pulmonary tuberculosis (TB) is key to effective outbreak management, and in humans thoracic radiography is used extensively for screening purposes. In wildlife TB radiography is a relatively accessible diagnostic tool, particularly in under-resourced settings, however its use is limited by body size. Sun bears are susceptible to human-associated TB, and their small body size makes thoracic radiography feasible.

Central and Obstructive Sleep Apnea (CSA and OSA), Chronic Obstructive Pulmonary Disease (COPD), and Obesity Hypoventilation Syndrome (OHS) disrupt breathing patterns, posing significant health risks and reducing the quality of life. Bilevel Positive Airway Pressure (BiPAP) therapy offers adjustable inhalation and exhalation pressures, potentially enhancing treatment adaptability for the above diseases. This is the first-ever study that employs Computational Fluid Dynamics (CFD) to examine the biomechanical impacts of BiPAP under four settings: Inspiratory Positive Airway Pressure (IPAP)/Expiratory Positive Airway Pressure (EPAP) of 12/8, 16/6, and 18/8 cmHO, compared to a without-BiPAP scenario of zero-gauge pressure.

Background: Despite the physiological advantages of positive end-expiratory pressure (PEEP), its optimal utilization during one-lung ventilation (OLV) remains uncertain. We aimed to investigate whether individualized PEEP titration by lung compliance is associated with a reduced risk of postoperative pulmonary complications during OLV.
Methods: We searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials until April 1, 2024, to identify published randomized controlled trials that compared individualized PEEP titration by lung compliance with fixed PEEP during OLV.
