bleeding AND bronchoscopy

BACKGROUND: Massive hemoptysis during pregnancy is very rare. Dieulafoy's disease is one of the causes of massive hemoptysis. There are few reports of ECMO use to treat massive hemoptysis during pregnancy. FINDINGS: We report for the first time a patient with Dieulafoy's disease diagnosed at 29 weeks of pregnancy. The patient's hemoptysis occurred rapidly with large volumes. The bleeding amount reached 500 ml within half an hour, with the development of asphyxia and respiratory and cardiac arrest due to a blood clot blocking the airway...

OBJECTIVE: Percutaneous dilatational tracheostomy (PDT) is a bedside applicable procedure in intensive care unit patients requiring long-term mechanical ventilation. Fiber optic bronchoscopy (FOB) makes it easier and reduces complications. Our study aimed to evaluate the indications, complications, and prognosis of PDTs performed with FOB. PATIENTS AND METHODS: Our study included 114 patients undergoing PDT through FOB-guided Griggs method in the Respiratory Intensive Care Unit between January 01, 2018, and January 31, 2023...

BACKGROUND: Flexible bronchoscopy-guided endobronchial biopsy (EBB) is routinely performed as an outpatient daycare procedure. Bleeding after EBB is a common complication, that at times disrupts the procedure and can rarely lead to a catastrophe. We aimed to compare the efficacy of prebiopsy prophylactic bronchoscopic electrocautery with adrenaline and cold saline instillation in achieving hemostasis in patients with endobronchial lesions with a higher risk of bleeding during EBB. METHODS: In this open-label, randomized controlled trial, 60 patients with endobronchial lesions were randomized to either the prophylactic electrocautery arm or the adrenaline and cold saline arm...

In France, even though it occurs only exceptionally in cases of hemopathy, severe hemoptysis in cancer is the leading cause of hemoptysis. Without adequate treatment, in-hospital mortality exceeds 60%, even reaching 100% at 6 months. The management of severe hemoptysis should be discussed with the oncologist. Aside from situations of threatening hemoptysis, in which bronchoscopy should be performed immediately, CT angiography is an essential means of localizing the bleeding and determining the causes and the vascular mechanisms involved...

Iatrogenic bleeding during bronchoscopy may lead to early termination, insufficient sample collection, decreased diagnostic accuracy, and even death. Unlike rigid bronchoscopy, the management of bleeding during flexible fiberoptic bronchoscopy does not allow the use of methods such as cautery, direct pressure, etc. and is usually limited to the application of liquids. The management of endobronchial bleeding usually depends on two main mechanisms: 1) vasoconstriction; 2) enhancing coagulation to form fibrin clots...

We report a case of a 59-year-old male who presented with a persistent cough for a year after being discharged from critical care following a subarachnoid haemorrhage. As part of his initial critical care management and in order to allow full neurological assessment, the patient required a period of prolonged mechanical ventilation, which necessitated a percutaneous tracheostomy. Following recovery and subsequent discharge, the patient presented on multiple occasions with cough, undergoing serial computed tomography (CT) scans which reported mucus plugging as a possible cause of the cough...

BACKGROUND: Transbronchial lung forceps biopsy (TBFB) is recommended before a surgical lung biopsy (SLB) when a definitive diagnosis of lymphangioleiomyomatosis (LAM) is required for patients without any additional confirmatory features. Transbronchial lung cryobiopsy (TBCB) has been suggested as replacement test in patients considered eligible to undergo SLB for the diagnosis of interstitial lung diseases. The efficacy and safety of TBCB were compared with that of TBFB and SLB in the diagnosis of LAM...

BACKGROUND: Aspirin has been shown to be safe for patients undergoing certain diagnostic bronchoscopy procedures, such as transbronchial biopsies and endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration. However, there are no studies documenting the safety of aspirin in patients undergoing trans -bronchial lung cryobiopsy (TBLC). OBJECTIVE: To determine whether aspirin increases the risk of bleeding during or following TBLC. METHODS: 172 consecutive patients undergoing TBLC were included in this retrospective cohort study...

We retrospectively reviewed the clinical data of patients aged 65 years and older with central airway stenosis who underwent therapeutic bronchoscopy under general anesthesia in Beijing Tiantan Hospital from January 2012 to September 2022. A total of 167 patients were included in the study. One or more comorbidities were present in 151 patients. The number of operation procedure was 230 times. Laryngeal mask ventilation under general anesthesia and electrotomy was the most common method of airway management and operation...

PURPOSE: Radial probe endobronchial ultrasound (RP-EBUS) accurately locates peripheral lung lesions (PLLs) during transbronchial biopsy (TBB). We performed an updated meta-analysis of the diagnostic yield of TBB for PLLs using RP-EBUS to generate recommendations for the development of the Korean Association of Lung Cancer guidelines. MATERIALS AND METHODS: We systematically searched MEDLINE and EMBASE (from Jan 2013 to Dec 2022), and performed a meta-analysis using R software...

BACKGROUND: The current concept of bronchoscopy-associated massive airway hemorrhage is not accurate enough, and the amount of bleeding as the only evaluation criterion cannot comprehensively evaluate magnitude of the effects and the severity. OBJECTIVE: To propose the concept of bronchoscopy-associated acute massive airway hemorrhage, analyze its impact on patients and highlight the treatment approach of acute massive airway hemorrhage without ECMO support. DESIGNS: A retrospective cohort study...

A percutaneous tracheostomy is a common surgical procedure done in intensive care. Several different techniques have been described. Recently, the addition of bronchoscopy or ultrasound has been advocated to decrease the risks and complications associated with the procedure; however, both aids used alone, bronchoscopy or ultrasound, have some drawbacks and pitfalls. In this manuscript, we describe a new technique implementing a new technology, Microendoscopy coupled with ultrasound to perform percutaneous dilation tracheostomy MUGPT...

Local anesthetic thoracoscopy (LAT) is a minimally invasive diagnostic procedure gaining recognition among chest physicians for managing undiagnosed pleural effusions. This single-port procedure is conducted with the patient under mild sedation and involves a contralateral decubitus position. It is performed in a sterile setting, typically a bronchoscopy suite or surgical theater, by a single operator with support from a procedure-focused nurse and a patient-focused nurse. The procedure begins with a thoracic ultrasound to determine the optimal entry point, usually in the IV-V intercostal space along the midaxillary line...

BACKGROUND: Transbronchial biopsy using an ultrathin bronchoscope (UTB) has a high diagnostic yield for peripheral pulmonary lesions (PPLs). When combined with peripheral transbronchial needle aspiration (pTBNA), it improves the diagnostic yield of "adjacent to" radial endobronchial ultrasonography (rEBUS) findings. However, pTBNA is a complicated technique, and the specimen volume is often inadequate for diagnostic and multiplex analyses. Recently, transbronchial cryobiopsy (TBCB) using a 1...

BACKGROUND: Transbronchial lung cryobiopsy (TBLC) in the diagnosis of diffuse parenchymal lung disease (DPLD) has shown a promising yield in recent times, with low post-procedural mortality and morbidity. OBJECTIVES: To compare the yield of TBLC and conventional transbronchial forceps lung biopsy (TBLB). METHODS: A prospective study was carried out in patients with DPLD over a period of 1 year in a tertiary respiratory care institute in New Delhi, India...

BACKGROUND: The efficacy of bronchial artery embolization (BAE) for bronchial Dieulafoy's disease (BDD) has not been well established. OBJECTIVE: This study aimed to evaluate the safety and efficacy of BAE in patients with clinically suspected BDD presenting with major hemoptysis, and to describe angiographic findings. METHODS: 17 patients (all men; mean age, 53.5 years) diagnosed with clinically suspected BDD by bronchoscopy (n = 7) or CT angiography (CTA) (n = 10) and who underwent BAE after directional and segmental localization of the target bronchus were enrolled...

BACKGROUND: The utility of bronchoscopy with bronchoalveolar lavage (BAL) in immunocompromised children is not well understood. We aim to describe the bronchoscopy diagnostic yield and complications and to investigate factors associated with diagnostic yield. METHODS: This is a single-center, retrospective cohort study of 60 children with leukemia or post-hematopoietic stem cell transplant who had a bronchoscopy with BAL between 2017 and 2021. Comparisons were done with regression analysis...

BACKGROUND: Hypoxia often occurs due to shared airway and anesthetic sedation-induced hypoventilation in patients receiving flexible bronchoscopy (FB) under deep sedation. Previous evidence has shown that supraglottic jet oxygenation and ventilation (SJOV) via Wei nasal jet tube (WNJ) reduces the incidence of hypoxia during FB. This study aimed to investigate the extent to which SJOV via WNJ could decrease the incidence of hypoxia in patients under deep sedation as compared to oxygen supplementation via WNJ alone or nasal catheter (NC) for oxygen supplementation during FB...

Many studies have reported electromagnetic navigation bronchoscopy (ENB) diagnostic yields and the importance of size and computed tomography (CT) bronchus sign. This study aimed to determine the diagnostic yield of ENB alone, using forceps biopsy and cytology. We analyzed the factors associated with yield and complications according to gross specimen size. This retrospective study included patients who underwent ENB using forceps for suspected lung lesions on CT between January 2020 and December 2022 in South Korea...
