110 Clinical Trials for Various Conditions
Randomized, pilot study that evaluates surveillance bronchoscopy versus no surveillance for patients that undergo tracheobronchial stenting
Bronchial Stents
In this study, the investigators plan to conduct a single blinded randomized controlled trial in the Pulmonary Service to demonstrate the efficacy of ketamine and its utility in moderate sedation. Patients presenting for bronchoscopy who meet inclusion criteria will be approached, and if amenable, will be consented and enrolled. Patients will be randomized to receive either 1 mg of midazolam and ketamine 0.25 to 0.5 mg/kg loading dose with subsequent doses of 10-20 mg IV or standard fentanyl and midazolam in 25mcg and 1mg increments respectively for moderate sedation during their procedure. The primary outcome will be patient satisfaction, which will be measured a using patient clinical satisfaction form. A number of secondary outcomes will include the following: (1) provider satisfaction (2) the time from sedation administration to procedure start (when the scope is inserted), (3) the time from sedation to scope removal from the trachea (4) the time from sedation to discharge (defined as the time from the end of the procedure until the patient meets discharge criteria from the recovery area), (5) total dose of medications given (including midazolam, fentanyl, and ketamine), (6) adverse events, (7) vital signs, (8) and the need for additional medications, in particular reversal agents.
Conscious Sedation, Patient Satisfaction, Ketamine
This is a single center study of 60 subjects including those with asthma and mucus plugging, those with asthma and without mucus plugging, and healthy controls. Screening data will be reviewed to determine participant eligibility. Participants who meet all inclusion criteria will participate in image-guided bronchoscopy ("virtual navigation bronchoscopy" \[VNB\]) to sample airway biospecimens in mucus plugged and control airways.
Asthma, Mucus; Plug, Tracheobronchial
This study aims to characterize airflow patterns during bronchoscopy under conscious sedation, and determine the incidence of obstructive and central respiratory events. The investigators also plan to monitor the degree and frequency of oxygen desaturation throughout the procedure. To achieve this, investigators use a physiologic monitoring device (NOX T3, K082113) that has been FDA approved for the screening and diagnosis of sleep disordered breathing \[1\]. The results from this pilot study will be used to assess the feasibility of a prospective study utilizing continuous external negative pressure (Pneuway). This negative pressure is applied through a neck mask to alleviate upper airway collapsibility and can potentially decrease the number of apneas during bronchoscopy under conscious sedation \[2\].
Conscious Sedation, Bronchoscopy
In this study, the feasibility of performing robotic navigation of peripheral airways in human subjects for the purpose of biopsying peripheral lung lesions will be evaluated.
Lung; Node
This randomized controlled pilot clinical trial will enroll patients undergoing dynamic flexible bronchoscopy will be randomized to receive one of the two anesthetic combinations described above. The study will determine if there is a difference when considering patient and physician and satisfaction when performing DFB. Also, safety and efficacy of the two pharmacological combinations (fentanyl + midazolam and remifentanil + ketamine) used will be evaluated.
Bronchoscopy
The purpose of this study is to investigate whether diagnostic bronchoscopy can be safely and potentially more effectively performed without the use of tracheal intubation or a supraglottic airway, under completely unobstructed surgical conditions afforded by THRIVE: Transnasal Humidified Rapid- Insufflation Ventilatory Exchange. THRIVE provides patient's gas exchange through rapid insufflation of high-flow oxygen via specialized nasal cannula.
Bronchoscopy
The purpose of this study is to evaluate outcomes following electromagnetic navigation bronchoscopy™ (ENB™) procedures using the superDimension™ navigation system.
Lung Lesion(s) Requiring Evaluation
A prospective, double-blind, randomized, placebo and active controlled, multi-center, parallel group study comparing remimazolam to placebo, with an additional open label arm for midazolam, in patients undergoing a bronchoscopy.
Bronchoscopy
This protocol hopes to determine whether the use of dexmedetomidine-ketamine can reduce the use of standard of care fentanyl-midazolam sedation during bronchoscopy. This may result in less respiratory depression while providing better compliance with the procedure.
Sedation
Optical coherence tomography will be a feasible adjunct to flexible bronchoscopy, and provide images with good sensitivity and specificity to determine the presence of endobronchial malignancies.
Lung Cancer
The investigators hypothesize that the scheduled use of bronchoscopy on a regular basis after inhalation injury in burn patients will improve outcome by providing pulmonary hygiene, decrease the incidence of pneumonia, and detect pneumonia earlier than standard treatment without bronchoscopy.
Inhalation Injury, Pneumonitis, Pneumonia
This study will evaluate the outcomes of bronchoscopy in Bome Marrow Transplant (BMT) patients who develop lung infiltrates suspicious for infections of the lungs. It will consist of two groups, one group will receive bronchoscopy within thirty six hours of enrollment, while the other group will receive bronchoscopy five days after enrollment. The purpose of this study is to determine the ideal time for bronchoscopy in this group of patients.
Bone Marrow Transplantation
The purpose of the study is to compare the three methods of bronchoscopic imaging to determine what combination is optimum to identify neoplastic mucosal abnormalities. The ability to decrease the rate of false-positive and false negative findings of bronchoscopy also will be studied for each spectroscopic technique separately and for their combination.
Lung Cancer
To determine safety and effectiveness of dexmedetomidine when administered for conscious sedation during flexible bronchoscopy (FB) in patients with Chronic Obstructive pulmonary Disease (COPD).
Sedation, Flexible Bronchoscopy, COPD
Very often patients receive medication before a diagnostic, therapeutic, or surgical procedure to help them relax, keep them calm, and to relieve them from pain. This is called procedural sedation. During procedural (mild-to-moderate) sedation, a patient is first given a pain-relief medication (analgesic) and then a medication to help him/her relax and keep him/her calm (sedative). Propofol is the drug commonly used for sedation because it releases immediately into the blood stream and causes fast sedation. AQUAVAN (fospropofol disodium) is made as a slow release version of propofol with a longer duration of effect.
Bronchoscopy, Anesthesia
Robotic-assisted bronchoscopy (RaB) has afforded proceduralists the ability to accurately reach the periphery of the lung for biopsy of pulmonary nodules1. This has paved the way for patients to undergo both biopsy of a peripheral nodule and a staging linear endobronchial ultrasound (EBUS) in the same anesthesia event, promoting quicker throughput from discovery of a lesion to guideline-adherent treatment2. Further, introduction and mainstream utilization of cone-beam CT (CBCT) has provided the bronchoscopist the ability to refine needle position with tool-in-lesion confirmation3. While there are no randomized clinical trials promoting efficacy of RaB and CBCT in comparison with other bronchoscopic methods, in single center retrospective studies, diagnostic yield has consistently proven to be in the 70-85% range, superior to prior technologies4-6. One of the limitations of utilization of RaB and CBCT is the detrimental effect that atelectasis plays in the bronchoscopy procedure. This can lead to false positive radial EBUS (rEBUS) signals and non-diagnostic procedures7. This incidence of atelectasis has been evaluated prospectively, using a protocol featuring 8-10 cmH2O of PEEP and limiting hyperoxia8, and results suggest this ventilator strategy does an adequate job preventing intraprocedural lung collapse. However, this study only evaluated incidence of atelectasis and did not elaborate on its impact on diagnostic yield. Further unknown is the optimal sequence of performance of RaB and a staging linear EBUS in patients with a radiographically normal mediastinum. Starting with either the RaB or Linear EBUS both have their pros and cons. The benefit to performance of a linear EBUS first is the potential to obviate the need for peripheral nodule biopsy by obtaining rapid, on-site pathologic feedback of occult nodal disease, reducing some of the risk of the procedure (i.e. bleeding and pneumothorax).6 Conversely, the pitfalls to performing linear EBUS first is the possible contribution of atelectasis resultant of the increased time from intubation to peripheral nodule biopsy, blood in the airway causing bronchospasm, and resorption atelectasis from hyperoxia9. There are no prospective data evaluating this in a randomized fashion, but one Monte Carlo simulation (with assumption of diagnostic yield from navigational bronchoscopy of 70% when performed first and 60% when performed second) suggested a higher diagnostic yield and less need for repeat procedure in the navigation first group, despite a 10% assumption of occult nodal disease10. As outlined in the specific aims above, the overarching goals of this study are to assess in a multicenter, randomized clinical trial performed by members of the Interventional Pulmonary Outcomes Group (IPOG), whether sequence of staging EBUS plays a role in diagnostic yield, incidence of atelectasis, and safety outcomes in patients undergoing RaB.
Pulmonary Nodules
RELIANT 2 is a pragmatic randomized controlled trial. The goal of this study is to compare the diagnostic yield of robotic assisted bronchoscopy with integrated cone beam computed tomography to that of electromagnetic navigation bronchoscopy with integrated digital tomosynthesis in patients undergoing bronchoscopy to biopsy a pulmonary lesion.
Peripheral Pulmonary Lesion, Lung Nodule, Solitary
The purpose of this research is to evaluate the ability of a new bronchoscope adapter called "leak-free adapter" to limit the amount of air leaking out to the operating room (OR) from the ventilator in intubated patients who undergo bronchoscopy.
Pulmonary Disease
The purpose of this study is to examine the mechanisms of asthma. The investigators are comparing the cells of individuals with and without asthma and looking at the roles various parts of the cell play in the production and secretion of mucus.
Asthma
Phase 1/1b, safety, feasibility, and light dose titration study followed by further study of therapeutic ablation effects. Patients with high risk of peripheral primary lung cancer, stage 1A1/1A2, for whom surgical treatment is planned, will be recruited. Surgery will be performed at 5-21 days following the VTP procedure. Study intervention: robotic assisted bronchoscopic Padeliporfin VTP lung ablation: vascular targeted photodynamic therapy using Padeliporfin photosensitizer.
Peripheral Lung Tumor
Thermal ablation (use of treatment modalities that generate heat) has become a widely used tool for treatment of central airway obstruction (e.g. laser, electrocautery, radiofrequency, and argon plasma coagulation). However, this method carries with it an increased risk for airway fire - a surgical fire that occurs in a patient's airway and could also include a fire in the attached breathing circuit. To decrease the risk of airway fire during mechanical ventilation with an endotracheal tube, the concentration of inspired oxygen (FiO2) is set below 40% while waiting for end tidal oxygen concentration (EtO2) to fall below 40% prior to starting thermal ablation. There is no published literature describing O2 concentration within the airways (AiO2) during jet ventilation with rigid bronchoscopy. The co-investigators of this study have recently collected data on AiO2 during rigid bronchoscopy using manual low frequency jet ventilation/high frequency jet ventilation with a period of apnea. The intent of this study is to measure the time taken for the central airway oxygen concentration to drop from 90 to 40% when the "laser mode" is activated on the Monsoon jet ventilator. Ventilation is continued during "laser mode."
Central Airway Obstruction
To learn if LADS is better than VESPA at preventing atelectasis during a robotic bronchoscopy.
Pulmonary, Lung
This is an investigator-initiated, cluster randomized controlled trial. The primary objective is to compare the diagnostic yield of the Ion™ Endoluminal System (SSCB) to the ILLUMISITE™ Platform (EMN bronchoscopy) in patients undergoing bronchoscopy for peripheral pulmonary lesion (PPL) evaluation.

Bronchi--Diseases, Lung Diseases, Obstructive, Lesions Mass
Navigational bronchoscopy (NB) is used to access peripheral and central parenchymal lung lesions via endobronchial and transbronchial approach. Currently there are multiple platforms available to provide guidance to reach the peripheral and central lesions in the lung which are inaccessible via traditional video bronchoscopy. Traditionally NB is done under fluoroscopic guidance using C-arm but with development of Cone Beam CT and 3D reconstruction technology, fluoroscopy can be enhanced to much higher resolution and can also provide real time 3D augmentation of the lesion. It also enables the user to obtain a CT of the Chest to confirm the real time location of the lesion and the bronchoscopic biopsy catheter and instruments. This has proven to improve the yield and sensitivity of Navigational bronchoscopic guided Biopsy of the lung nodules and masses. Out of the various navigational platforms we have, most of them are based on Electromagnetic guidance and some on Shape sensing technology. Some of the platforms have fixed angle catheter while the newer robotic platforms have articulating catheters with much more range of motion. So far we do not have any data directly comparing the diagnostic yield of Electromagnetic navigational bronchoscopy with Robotic shape sensing guided bronchoscopy while using Cone Beam CT and Augmented fluoroscopy with both the platforms. With my study, I want to examine the change in diagnostic yield and sensitivity of fixed angle ENB guided bronchoscopy and articulating robotic shape sensing bronchoscopy both using Cone Beam CT with 3D reconstruction.
Lung Nodule, Lung Mass, Lung Cancer
This is a prospective, multicenter, single-arm study on transbronchial microwave ablation using the NEUWAVE FLEX Microwave Ablation System and Accessories on oligometastatic tumors in the peripheral lung, guided by the Auris MONARCH Platform for visualization and access while using cone beam CT (computed tomography) to confirm probe tip placement and final ablation zone. The primary endpoint is Technique Efficacy, assessed 30-days post-ablation via CT imaging.
Lung Neoplasms
This study is designed to evaluate the safety and feasibility of real-time needle-based confocal laser endomicroscopy (nCLE) in improving diagnostic accuracy of robotic-assisted bronchoscopy (RANB) biopsy performed with the Monarch® Endoscopy Platform in patients with peripheral pulmonary nodules (PPN).
Lung Neoplasms
This study investigates whether using a mobile-CT-assisted bronchoscopy (M-CAB) during a bronchoscopy procedure will better enable the study staff to reach the lung tumor, perform a biopsy, and obtain a diagnosis. One method that doctors use for diagnosing lung tumors is bronchoscopy guided by an X-ray machine (called fluoroscope). Though much better guidance could be provided with a CT scanner when compared to the fluoroscope, the standard CT equipment is very large, fixed in a radiology room, and difficult to use with bronchoscopy. Mobile CT imaging systems may more easily and effectively perform the same tasks of the standard CT imaging in the bronchoscopy room, offering better guidance than the standard fluoroscope.
Lung Neoplasm
This phase II trial studies the use of Ion robotic bronchoscope with a mobile computed tomography (CT) scanner to biopsy tumors and inject a fluorescent dye called indocyanine green to mark the tumor during surgery in patients with stage I non-small cell lung cancer or cancer that has spread to the lung (lung metastases). Sometimes small tumors or those that are not on the surface of the lung can be challenging to remove without making larger incisions. Injecting the dye, may help doctors see the tumor more easily, which may allow for smaller incisions and by being able to see the tumor, doctors may be better able to decide where to make the incisions in order to get all of the tumor out.
