A 27-year-old woman sustained a blunt chest trauma after a car accident. Computed tomography revealed tension pneumopericardium, bilateral pneumothorax, and a suspected rupture of the left main bronchus. Emergent pericardial needle aspiration was successfully performed. Bronchial amputation was confirmed by bronchofiberoscopy. Despite total detachment of the distal part of the bronchial tree, the ventilation of the left lung was maintained without air leakage by use of pleural drains. Bronchial obturation resulted from the injury, and was effectively treated by bronchoscopic sputum suction at the distal end of the bronchus...

BACKGROUND: The success of needle decompression for tension pneumothorax is variable, and there are no objective measures assessing effective decompression. Colorimetric capnography, which detects carbon dioxide present within the pleural space, may serve as a simple test to assess effective needle decompression. METHODS: Three swine underwent traumatically induced tension pneumothorax, (n=15 standard of care, n=15 with needle capnography). Standard of care needle thoracostomy (n=15) using an 8 cm angiocatheter was performed...

BACKGROUND: The Infant Jarvik 2015 is an implantable axial-flow ventricular assist device (VAD) that has undergone the major evolutionary design modifications to improve hemocompatibility. This study was conducted in anticipation of data submission to the US Food and Drug Administration to obtain Investigational Device Exemption approval. METHODS: The VAD was implanted via a left thoracotomy in Barbado sheep (n = 10, 26 (19-34] kg). Anticoagulation was maintained with coumadin, with a target international normalized ratio of greater than the individual sheep's baseline values...

Pleuropulmonary blastoma (PPB) is a very rare, highly aggressive, and malignant tumor that originates from either lungs or pleura. It occurs mainly in children aged <5 or 6 years. It has poor prognosis with three different subtypes: cystic (type I), combined cystic and solid (type II), and solid (type III). PPB is treated with aggressive multimodal therapies including surgery and chemotherapy. We present a case of PPB in a 3-year-old girl who presented with tension pneumothorax.

We present a unique case of a patient with a tension pneumothorax that presented with electrocardiogram (ECG) characteristics typical for ST segment elevation myocardial infarction. The clinical diagnosis was clinched by focused physical examination. Treatment of the pneumothorax lead to resolution of the electrocardiographic abnormalities. Our experience from this unique case is useful for cardiologists and critical care physicians who encounter these patients routinely.

BACKGROUND: When gunshot and blast injuries affect only a single person, first aid can always be delivered in conformity with the relevant guidelines. In contrast, when there is a dynamic casualty situation affecting many persons, such as after a terrorist attack, treatment may need to be focused on immediately life-threatening complications. METHODS: This review is based on pertinent publications retrieved by a selective search in Medline and on the authors' clinical experience...

PURPOSE: To determine the rate, clinical significance, and predictors of delayed pneumothorax after CT-guided lung biopsy. METHODS: Medical and imaging records of all patients who underwent CT-guided lung biopsy between January 1, 2012, and January 9, 2015, were reviewed. "Early pneumothorax" was defined as one visualized on CT scan at the time of biopsy, "delayed pneumothorax" as one discovered on the first follow-up chest X-ray (CXR), and "clinically significant pneumothorax" as one requiring chest tube placement...

BACKGROUND: Spontaneous pneumothorax (SP) is uncommon and can present as a primary disease process or as a result of underlying lung pathology. Several parenchymal lung diseases, such as malignancy, are known to cause SP. One such malignancy, angiosarcoma, has a high propensity to metastasize to the lung and present as cavitary and cystic lesions. CASE: We present a case of a 76-year-old male diagnosed with angiosarcoma of the scalp that was found to have extensive cystic pulmonary metastatic lesions...

BACKGROUND: Tension pneumothorax (tPTX) remains a significant cause of potentially preventable death in military and civilian settings. The current pre-hospital standard of care for tPTX is immediate decompression with a 14 gauge 8cm angiocatheter (14G AC); however, failure rates may be as high as 17-60%. Alternative devices, such as 10G AC, modified Veress needle (mVN) and laparoscopic trocar (LT), have shown to be potentially more effective in animal models; however, little is known about the relative insertional safety or mechanical stability during casualty movement...

A 34-year-old woman at 25 weeks 3 days was diagnosed with preterm labor and underwent an emergency cesarean section. The neonate did not cry or show any activity. The heart rate was 80 beats/min and the oxygen saturation on pulse oximetry (SpO2) was 77%. Immediately, positive pressure ventilation was delivered by T piece resuscitator, and then anesthesiologist performed endotracheal intubation. The neonate demonstrated severe cyanosis and the SpO2 dropped to 30%. Ventilation was not successful even after intubation, and we found neck crepitus, chest wall distension, and severe cyanosis on physical examination...

BACKGROUND: Delayed recognition of tension pneumothorax can lead to a mortality of 31% to 91%. However, the classic physical examination findings of tracheal deviation and distended neck veins are poorly sensitive in the diagnosis of tension pneumothorax. Point-of-care ultrasound is accurate in identifying the presence of pneumothorax, but sonographic findings of tension pneumothorax are less well described. CASE REPORT: We report the case of a 21-year-old man with sudden-onset left-sided chest pain...

BACKGROUND: Spontaneous pneumomediastinum is defined as the presence of free air in the mediastinum without any apparent concomitant factors or disease. It is uncommon but usually benign and self-limiting. Generally, patients with spontaneous pneumomediastinum are admitted to hospital, and occasionally, prophylactic antibiotics are administered to prevent mediastinitis. The purpose of this study was to describe practices concerning the feasibility of outpatient treatment and follow-up of spontaneous pneumomediastinum and the necessity of prophylactic antibiotics...

BACKGROUND: Subcutaneous emphysema is defined as presence of air or gas in subcutaneous tissue layer. It may be localized or generalized due to various aetiological factors. Although SE and pneumomediastinum are self-limiting conditions, life-threatening complications may develop. Escape of air into both pleural cavity causing bilateral pneumothorax and tension pneumothorax can be termed as malignant emphysema. PURPOSE: To report a case of malignant generalized subcutaneous emphysema in early postoperative phase following palatoplasty...

OBJECTIVE: We aim to summarize current evidence on the value of point-of-care (POC) focused echocardiography in the assessment of short-term survival in patients with cardiac arrest. METHODS: PubMed and EMBASE were searched from inception to July 2016 for eligible studies that evaluated the utility of POC echocardiography in patients with cardiac arrest. Modified QUADAS was used to appraise the quality of included studies. A random-effect bivariate model and a hierarchical summary receiving operating curve were used to summarize the performance characteristics of focused echocardiography...

The clinical presentation of pneumothorax is highly variable. Spontaneous pneumothoraces may present with subtle symptoms when a small air leak is present, but can progress to hemodynamic instability in the setting of tension physiology. The etiologies are broad and the severity can vary greatly. A trauma patient with a pneumothorax may also have the added complexity of other potentially life-threatening injuries. While there is a wealth of evidence-based guidelines for the management of pneumothoraces in the adult literature, the approach to pediatric patients is largely extrapolated from that literature without a significant evidence base...

INTRODUCTION: Arthroscopy has become a major diagnostic tool and treatment option for shoulder pathology. However rare, respiratory complications such as a pneumothorax have been reported in patients undergoing shoulder arthroscopy. Surgery - as well as anesthesiology-related factors and respiratory comorbidity have been hypothesized to intervene in the onset of respiratory complications. CASE REPORT: We report the case of a 42-year-old male patient who underwent an arthroscopy of the left shoulder...

Severe and critical central airway obstruction causing impaired ventilation and/or oxygenation can impose tremendous challenges on the interventional pulmonologist. Near total airway obstruction can rapidly evolve into potentially fatal complete airway occlusion during bronchoscopic airway manipulation under moderate sedation; as well as during the induction of the general anesthesia. Although there are currently interventional pulmonary procedures available to tackle the critical airway obstruction in extreme situations, cardio-pulmonary bypass should be considered prior to the intervention to maintain the adequate gas exchange during the procedure...

PURPOSE: Peroral endoscopic myotomy (POEM) is a novel technique for treating esophageal achalasia. During POEM, carbon dioxide (CO2) is insufflated to aid surgical dissection, but it may inadvertently track into surrounding tissues, causing systemic CO2 uptake and tension capnoperitoneum. This in turn may affect cardiorespiratory function. This study quantified these cardiorespiratory effects and treatment by hyperventilation and percutaneous abdominal needle decompression (PND). METHODS: One hundred and seventy-three consecutive patients who underwent POEM were included in this four-year retrospective study...
