INTRODUCTION: Size 9 and 8 airways for men and women, respectively, have been proposed as most appropriate based on endoscopy. However, a limitation of this guideline is that ventilation was not assessed. METHODS: In this retrospective review of prospectively collected data, 149 patients requiring tracheal intubation for general anesthesia were included. The adequacy for manual and pressure-controlled mechanical ventilation and views at the distal end of each airway was assessed using a fiber-optic bronchoscope with various airway sizes (7, 8, 9, 10, and 11)...

Chronic obstructive pulmonary disease (COPD) is a progressive lung disease characterized by pathophysiological factors including airflow limitation, hyperinflation and reduced gas exchange. Treatment consists of lifestyle changes, lung rehabilitation and pharmacological therapies such as long acting beta-2-agonists (LABA) and long acting muscarinic antagonists (LAMA). More recently bronchoscopic treatments are emerging for COPD. Among them endobronchial valves(EBV) and endobronchial coils (EBC), next to endobronchial stents, sclerosing agents, targeted lung denervation and liquid nitrogen metered cryospray...

BACKGROUND: Hemoptysis can cause a life threatening condition and often need to be treated urgently. Nearly 20% of hemoptysis cases were diagnosed as cryptogenic after clinical investigation. The purpose of this study was to clarify clinical and angiographic characteristics of cryptogenic hemoptysis. METHODS: We retrospectively reviewed medical records of 35 patients admitted to our hospital with cryptogenic hemoptysis from October 2010 to September 2014. RESULTS: In the 35 cases, bronchial artery embolization was successfully performed in 33 patients (94...

OBJECTIVE: To observe the effect of endotracheal tube with subglottic suction line on tracheostomy bleeding in critical patients. METHODS: This procedure was utilized for 35 critical patients with tracheostomy bleeding. With the help of bronchoscope, the endotracheal tube with subglottic suction line was inserted during tracheostomy to 0.5-1.0 cm above the carina. Then aerocyst of the tube was inflated, vacuum was set up for continuous suction via suction port, and hemocoagulase was injected to the opening of tracheostomy...

One case of successful primary closure of a bronchopleural fistula (BPF) after right pneumonectomy by sealing from both inside the chest cavity and bronchus is reported. The patient was a 47-year-old man who underwent right pneumonectomy due to right lung total collapse and atelectasis which was long-term compressed by a huge cyst inside the right chest cavity. A BPF was found on day 20 after surgery. A thoracotomy approach was performed because it was difficult to find an appropriate location for close drainage...

A 69-year-old woman developed central airway obstruction due to invasive Aspergillus infection resulting in pseudomembranous tracheobronchitis (PTB). Several challenges were encountered in the airway management of this patient including her having relatively smaller airways which were more prone to obstruction by pseudomembranes and made airway interventions difficult. The patient had clinical deterioration in spite of antifungal therapy and bronchoscopic debridement. The multimodality airway techniques included the use of smaller biliary balloons for dilatation, using a hybrid stent to slowly dilate and maintain patency of right main stem and finally the insertion of right secondary carina peripheral Y stent, which resulted in clinical improvement and allowed time for antifungal therapy to take effect...

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...

Damage to the endotracheal tube (ETT) is common in head and neck surgeries, especially in maxillary osteotomy. Airway management in such a crisis is crucial as there is risk of aspiration of blood into lungs, hypoxia and apnoea. This case illustrates a patient with an anticipated difficult airway who had an intraoperative damage to the ETT and was successfully managed by re-intubation with fiberoptic bronchoscope in a minimal apnoea period of <15 s using a new technique.

BACKGROUND AND AIMS: The Airtraq™ optical laryngoscope is the only marketed videolaryngoscope for paediatric patients besides the fibre-optic bronchoscope. We hypothesized that intubation would be easier with Airtraq™ compared to Miller blade. Hence, we compared Airtraq™ with the Miller laryngoscope as intubation devices in paediatric patients. METHODS: This prospective, randomized study was conducted in a tertiary care teaching hospital. Sixty children belonging to American Society of Anesthesiologists' Grade I-II, aged 2-10 years, posted for routine surgery requiring tracheal intubation were randomly allocated to undergo intubation using a Miller (n = 30) or Airtraq™ (n = 30) laryngoscope...

BACKGROUND AND AIMS: Video Stylet (VS) is a new intubating modality that provides real-time video of endotracheal intubation (ETI). This device does not need alignment of the oral, pharyngeal and tracheal axes to view glottis and can be used in patients with limited mouth opening. The aim of this study was to compare flexible fibre-optic (FO) bronchoscope with VS in elective surgical patients in apparently normal airway patients requiring oral ETI. METHODS: Sixty patients undergoing elective surgery under general anaesthesia of age group 20-60 years, weight 40-70 kg, American Society of Anesthesiologist 1 and 2 and modified Mallampatti I and II were included in the study...

Oesophageal ultrasound with bronchoscope (EUS-B) is designed to evaluate mediastinal structures. We describe a case of a 78-year-old woman who presented with altered mental status for 2 weeks. CT head revealed a subacute infarct in the right middle cerebral artery distribution. She was also found to have a lung mass on chest imaging. EUS-B-guided fine needle aspiration demonstrated the presence of adenocarcinoma in station 7 lymph node and in the mass. Immunohistochemistry confirmed it to be a lung primary as the Thyroid Transcription Factor-1 (TTF-1) was strongly positive...

Purpose To evaluate whether bronchoscopic lung volume reduction (BLVR) increases ventilation and therefore improves ventilation-perfusion (V/Q) mismatch. Materials and Methods All patients provided written informed consent to be included in this study, which was approved by the Institutional Review Board (2013-0368) of Asan Medical Center. The physiologic changes that occurred after BLVR were measured by using xenon-enhanced ventilation and iodine-enhanced perfusion dual-energy computed tomography (CT). Patients with severe emphysema plus hyperinflation who did not respond to usual treatments were eligible...

OBJECTIVE: Children with Tetralogy of Fallot, Pulmonary Atresia, and Major Aortopulmonary Collaterals (TOF/PA/MAPCAs) undergoing unifocalization surgery are at risk for developing more postoperative respiratory complications than children undergoing other types of congenital heart surgery. Bronchoscopy is used in the perioperative period for diagnostic and therapeutic purposes. In this study, we describe bronchoscopic findings and identify factors associated with selection for bronchoscopy...

Herein, we describe our experience in treating a case of primary pulmonary mucosa-associated lymphoid tissue lymphoma detected as a nodular opacity. A 79-year-old man was referred to our hospital. Computed tomography showed a nodular opacity measuring 20 mm in diameter with regular margins in segment 5 of the right middle lobe of the lung. Although the bronchoscopic brush cytology result was class III, the patient was tentatively diagnosed with suspected mucosa-associated lymphoid tissue lymphoma. A thoracoscopic right middle lobectomy was performed...

BACKGROUND: Acute respiratory distress syndrome causes a heterogeneous lung injury with normal and acutely injured lung tissue in the same lung. Improperly adjusted mechanical ventilation can exacerbate ARDS causing a secondary ventilator-induced lung injury (VILI). We hypothesized that a peak airway pressure of 40 cmH2O (static strain) alone would not cause additional injury in either the normal or acutely injured lung tissue unless combined with high tidal volume (dynamic strain). METHODS: Pigs were anesthetized, and heterogeneous acute lung injury (ALI) was created by Tween instillation via a bronchoscope to both diaphragmatic lung lobes...

BACKGROUND: Percutaneous dilatational tracheostomy (PDT) in critically ill patients is often led by optical guidance with a bronchoscope. This is not without its disadvantages. Therefore, we aimed to study the feasibility of a recently introduced endotracheal tube-mounted camera (VivaSight™-SL, ET View, Misgav, Israel) in the guidance of PDT. METHODS: We studied 10 critically ill patients who received PDT with a VivaSight-SL tube that was inserted prior to tracheostomy for optical guidance...

Lung cancer is the most deadly form of cancer in part because of the challenges associated with accessing nodules for diagnosis and therapy. Transoral access is preferred to percutaneous access since it has a lower risk of lung collapse, yet many sites are currently unreachable transorally due to limitations with current bronchoscopic instruments. Toward this end, we present a new robotic system for image-guided trans-bronchoscopic lung access. The system uses a bronchoscope to navigate in the airway and bronchial tubes to a site near the desired target, a concentric tube robot to move through the bronchial wall and aim at the target, and a bevel-tip steerable needle with magnetic tracking to maneuver through lung tissue to the target under closed-loop control...
