Air leak syndrome

BACKGROUND AND OBJECTIVES: An increasing number of children with diverse medical conditions are using long-term noninvasive ventilation (NIV). This study examined the impact of demographic, clinical, and technology-related factors on long-term NIV adverse events in a large cohort of children using long-term NIV. METHODS: This was a multicenter retrospective review of all children who initiated long-term NIV in the province of Alberta, Canada, from January 2005 to September 2014, and followed until December 2015...

Air leak syndrome (ALS) is defined as the extrusion of air from an aerated compartment into an unaerated compartment with associated symptoms of respiratory distress. This syndrome can occur as a consequence of trauma, iatrogenic causes, or spontaneously. Retrospective investigations conducted in the adult population have demonstrated an elevated risk of spontaneous ALS development in patients with coronavirus disease 2019 (COVID-19) pneumonia, along with its correlation with mortality. However, no studies have yet explored this phenomenon within the pediatric population...

Most extremely preterm infants (EPIs), who were born before 28 weeks of gestation, with pulmonary air leak syndrome (ALS) are symptomatic, often severe, and require drainage. EPIs with severe air leak syndrome (sALS) that require tube drainage or needle aspiration are at high risk of morbidities and mortality. This study aimed to investigate perinatal characteristics, morbidities, and mortality in EPIs with sALS, and to estimate the risk of mortality according to gestational age (GA). A prospective cohort study conducted from 2013 to 2020 compiled the Korean Neonatal Network database to evaluate the incidence, perinatal characteristics, and outcomes of sALS in EPIs born before 28 weeks of gestation...

BACKGROUND AND AIMS: Thoracic air leak syndrome (TALS) is a complication related to chronic pulmonary graft-versus-host disease (pGvHD) that affects approximately 0.83%-3.08% patients after allogenic hematopoietic stem cell transplant. Such complication is defined as the occurrence of any form of air leak in the thorax, including spontaneous pneumomediastinum or pneumopericardium, subcutaneous emphysema, interstitial emphysema and pneumothorax and has a negative impact on post-transplant survival...

INTRODUCTION: Pneumoperitoneum is the presence of air within the peritoneal cavity and is mostly caused by organ rupture. Spontaneous pneumoperitoneum accounts 5% to 15% of the cases and occurs in the absence of organ damage. The pulmonary origin of pneumoperitoneum is unusual, and probably associated with mechanical ventilation and alveolar leak. In patients with coronavirus disease 2019 (COVID-19) there are some reports of air leak, like pneumothorax, pneumomediastinum, pneumoperitoneum, and subcutaneous emphysema...

Acute respiratory distress syndrome (ARDS) and acute lung injury have a diverse spectrum of causative factors including sepsis, aspiration of gastric contents, and near drowning. Clinical management of severe lung injury typically includes mechanical ventilation to maintain gas exchange which can lead to ventilator-induced lung injury (VILI). The cause of respiratory failure is acknowledged to affect the degree of lung inflammation, changes in lung structure, and the mechanical function of the injured lung...

Extracorporeal CO2 removal (ECCO2R) is a therapeutic approach that allows protective ventilation in acute respiratory failure by preventing hypercapnia and subsequent acidosis. The main indications for ECCO2R in acute respiratory failure are COPD (chronic obstructive pulmonary disease) exacerbation, acute respiratory distress syndrome (ARDS) and other situations of asthmatics status. However, CO2 removal procedure is not extended to those ARDS patients presenting an air leak. Here, we report three cases of air leaks in patients with an ARDS that were successfully treated using a new ECCO2R device...

RATIONALE: In recent few years, high-flow nasal oxygenation (HFNO) has been widely used for management of acute hypoxemic respiratory failure and during postextubation periods, including after endotracheal intubation general anesthesia (ETGA). However, HFNO generates positive pressure in the injured airway following removal of endotracheal tube may cause airway leaks. This is the first case report of severe airway leak syndrome following postextubation use of HFNO in surgical patients...

BACKGROUND: Pulmonary complications, such as airway leak syndrome, are common in preterm neonates; however, bronchial rupture is a rarely seen phenomenon. CASE PRESENTATION: In this case, we present a preterm newborn who developed pneumomediastinum and pneumothorax. The pneumothorax persisted, despite placement of a thorax tube, requiring a thoracotomy to detect and treat the bronchial rupture. CONCLUSION: Physicians should have a high suspicion of bronchial rupture in patients with persistent air leak syndrome, even after thorax tube placement and continuous negative pressure implementation...

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pneumonia is reportedly associated with air leak syndrome (ALS), including mediastinal emphysema and pneumothorax, and has a high mortality rate. In this study, we compared values obtained every minute from ventilators to clarify the relationship between ventilator management and risk of developing ALS. METHODS: This single-center, retrospective, observational study was conducted at a tertiary care hospital in Tokyo, Japan, over a 21-month period...

Hamman's syndrome, or spontaneous pneumomediastinum, is the presence of air in the mediastinum without a history of previous pulmonary pathology, chest trauma or iatrogenesis. It has been described as a rare complication in patients with COVID-19 pneumonia. It is postulated that an increase in airway pressure associated with diffuse alveolar damage caused by the virus produces an air leak into the mediastinum. Chest pain and dyspnea associated with subcutaneous emphysema should make the treating physician suspicious...

BACKGROUND: Plastic bronchitis (PB) is a rare and severe lung disease. It can be triggered by influenza virus infection, which is a common respiratory infection in children. Bronchoscopy can aid in the early detection and treatment of PB. However, the outcomes and risk for PB development in pediatric patients with influenza virus infection are not fully understood. METHODS: Data from 321 children diagnosed with influenza virus pneumonia who underwent bronchoscopy examinations between 1st January, 2009 and 31st December, 2020 were retrospectively analyzed to assess the outcomes and risk factors associated with PB development...

Pneumocephalus is the presence of air in the intracranial space and has multiple causes, including cerebral air embolism. Its presentation may range from asymptomatic to decrease mental status, coma, and seizures. We present a case of cerebral air embolism secondary to acute bleeding inside an emphysema bulla. A 69-year-old female was brought to the emergency room after suffering acute dyspnea, convulsions, and cardiac arrest during a commercial flight. The Head CT showed the presence of multiple small gas collections in the brain, and the Thoracic Angiotomography showed a thin-walled bulla surrounded with pulmonary venous vascular structures and signs of active bleeding...

Nasal continuous positive airway pressure (nCPAP) is a safe, effective, non-invasive respiratory modality to deliver positive end expiratory pressure in neonates. Many studies have established its associated improved respiratory outcomes without increase in major morbidities associated with preterm neonates. In contrast, there is paucity in literature addressing complications such as nasal injury, abdominal distention, air leak syndromes (especially pneumothorax), hearing loss, heat and chemical burns, swallowing and aspiration of small components of the nasal interface and delay in escalation of respiratory support associated with the use of nCPAP, most frequently due to its incorrect use...

We presented the case of an adult patient with hyper-IgE syndrome (HIES) who was admitted acutely with a large hydropneumothorax from lung consolidation, a bronchopleural fistula and pleural infection. He has had recurrent pulmonary and skin infections since childhood and longstanding pneumatoceles. He was treated with systemic antibiotics and chest tube drainage. Administration of two doses of low-dose intrapleural therapy (1 mg tissue plasminogen activator and 5 mg deoxyribonuclease) allowed complete evacuation of his residual loculated pleural fluid, aided resolution of his infection without provoking a significant air leak and avoided the need for surgery...

Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterised by relapsing and remitting mucosal inflammation of the colon. Despite primarily affecting the gastrointestinal tract, UC has various extraintestinal manifestations that often affect other organs and systems. Although pulmonary involvement is uncommon, organising pneumonia (OP), which affects the lung parenchyma, is one of the potential extraintestinal manifestations of UC. We report a case of OP in a 35-year-old male with a longstanding history of UC, well-medicated with sulfasalazine (SSZ)...

INTRODUCTION: Patients with acute respiratory distress syndrome (ARDS) on mechanical ventilation often require high inspiratory pressure and positive end-expiratory pressure (PEEP). However, effective ventilation becomes difficult in cases where a large air leak develops in patients. The management of such a case requires improvisation and the adoption of special ventilation strategies. CASE AND OUTCOMES: We present a case study of a burn patient with airway involvement, developing ARDS and who developed a bronchopleural fistula (BPF) leading to failure of conventional ventilation...

OBJECTIVE: To analyze neonatal outcomes in very-low-birthweight (VLBW) infants depending on the presence of preterm premature rupture of membranes (PPROM), oligohydramnios, or both. METHODS: The electronic medical records of VLBW infants admitted during the study period, January 2013 to September 2018, were reviewed. Neonatal outcomes (primary outcome: neonatal death; secondary outcome: neonatal morbidity) were compared depending on whether the infant was affected by PPROM or oligohydramnios...
