OBJECTIVES: To verify the association between the air leak objectively measured intraoperatively (IAL) using the ventilator and the air leak duration after pulmonary lobectomy. METHODS: Prospective analysis on 111 patients submitted to pulmonary lobectomy (33 by video-assisted thoracic surgery). After resection, objective assessment of air leak (in milliliter per minute) was performed before closure of the chest by measuring the difference between a fixed inspired and expired volume, using a tidal volume of 8 ml/kg, a respiratory rate of 10 and a positive-end expiratory pressure of 5 cmH 2 O...

OBJECTIVE: Hemopneumothorax (HPTX) is the second leading cause of potentially preventable death among combat casualties. We investigated the ability of five FDA-approved non-occlusive chest seals (CSs) to seal a bleeding chest wound and prevent tension HPTX in a swine model. METHODS: Following instrumentation, an open chest wound was created in the left thorax of spontaneously air-breathing anesthetized pigs (n=26, 43 Kg). Autologous fresh blood (226 mL) was then infused into the pleural cavity to produce HPTX...

RATIONALE: Numerous types of flap coverage have been reported to prevent or to repair bronchopleural fistulas. Most of the flaps were harvested from chest area. However, these pedicled flaps might not be optimal for the patient who has undergone previous radiotherapy on pulmonary parenchyma because the pedicle artery of the flap might have been injured by irradiation. Therefore, an alternative flap outside of the chest area is necessary. PATIENT CONCERNS: A 61-year-old male was diagnosed of squamous cell carcinoma in right upper lobe lung (cT3N2M0, stage IIIa)...

INTRODUCTION: Minimally invasive surgery is the treatment of choice in early-stage lung cancer. However, experience in infectious lung disease, primarily bronchiectasis, is limited probably because of the presence of dense pleural adhesions, multiple lymph nodes, and spiral bronchial arteries. The present study shows our experience of video-assisted thoracoscopic surgery (VATS) lobectomy and segmentectomy in the treatment of bronchiectasis. MATERIALS AND METHODS: Patients who underwent VATS lobectomy or segmentectomy in our clinic between April 2008 and 2015 were retrospectively evaluated...

BACKGROUND: We sought to evaluate the clinical utility of chest tube management after pulmonary resection based on objective digital monitoring of pleural pressure and digital surveillance for air leaks. METHODS: We prospectively recorded the perioperative data of 308 patients who underwent pulmonary resection between December 2013 and January 2016. We used information from a digital monitoring thoracic drainage system to measure peak air leakage during the first 24 hours after the operation, patterns of air leakage over the first 72 hours, and patterns of pleural pressure changes until the chest tubes were removed...

Patients who have acute respiratory distress syndrome (ARDS) with persistent air leaks have worse outcomes. Endobronchial valves (EBV) are frequently deployed after pulmonary resection in noncritically ill patients to reduce and eliminate bronchopleural fistulas (BPFs) with persistent air leak (PAL). Information regarding EBV placement in mechanically ventilated patients with ARDS and high volume persistent air leaks is rare and limited to case reports. We describe three cases where EBV placement facilitated endotracheal extubation in patients with severe respiratory failure on prolonged mechanical ventilation with BPFs...

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: For primary lung cancer, anatomic pulmonary segmentectomy may have a functional advantage over lobectomy; however, persistent air leak or delayed pneumothorax after segmentectomy is prevalent and increases surgical morbidity. To prevent pulmonary complications after pulmonary segmentectomy, we used 2 methods for the involved intersegmental plane: coverage using polyglycolic acid mesh and fibrin glue (mesh cover) or closing it by suturing the pleural edge (pleural suture). We aimed to compare postoperative pulmonary function and complications between the 2 groups...

Organizing pneumonia (OP) is a less common interstitial lung disease with varying clinical picture. The development of pulmonary air leak in a case of OP is an extremely rare complication. Here, we report the case of a 46-year-old female with carcinoma ovary, postchemotherapy who developed respiratory distress with pneumomediastinum, and subcutaneous emphysema. Lung biopsy showed evidence of OP. This turned out to be a rare case of OP, secondary to bleomycin chemotherapy, presenting with pulmonary air leak.

Spirulina was cultivated in cathodic compartments of photo-microbial fuel cells (P-MFC). Anodic compartments were fed with swine-farming wastewater, enriched with sodium acetate (2.34gCODL(-1)). Photosynthetic oxygen generation rates were sufficient to sustain cathodic oxygen reduction, significantly improving P-MFC electrochemical performances, as compared to water-cathode control experiments. Power densities (0.8-1Wm(-2)) approached those of air-cathode MFCs, run as control. COD was efficiently removed and only negligible fractions leaked to the cathodic chamber...

OBJECTIVE: Single-surgeon cohorts assessing robotically assisted video-assisted thoracic (RA-VATS) lobectomy have reported good outcomes, but there are little data regarding multiple surgeons applying a standard technique in separate hospitals. The purpose of this study was to show how a standardized robotic technique is both safe and reproducible between surgeons and institutions. METHODS: From July 1, 2012, to October 1, 2013, patients undergoing RA-VATS lobectomy for both benign and malignant disease were identified from a prospectively collected database of two thoracic surgeons from different hospitals within the same healthcare system and retrospectively analyzed...
