Chewing Gum and Cold Gargle on Post-Bronchoscopy Symptoms: A Randomized Controlled Study

This study aims to evaluate the effects of chewing gum and gargling with cold water on common post-bronchoscopy symptoms, such as sore throat and difficulty swallowing (dysphagia). Bronchoscopy is a procedure that can cause temporary throat discomfort. In this randomized controlled trial, patients will be divided into groups to receive either chewing gum, cold water gargle, or standard care. The researchers will then measure and compare patient satisfaction levels and the severity of throat symptoms to determine if these simple interventions can improve patient comfort after the procedure.

Shape-Sensing Robotic-Assisted Bronchoscopy for Diagnosis of Peripheral Pulmonary Nodules in Korea

What is this study about? This study tests a new robotic technology to take tissue samples from lung nodules (small spots in the lungs). Some lung nodules are cancer, but doctors need a tissue sample to know for sure. What is the problem? Current methods to get tissue from lung nodules only work about 7 out of 10 times. When they don't work, doctors may need riskier procedures. What is the new technology? The new technology is called robotic bronchoscopy (ssRAB). It uses a robot with special sensors to guide a thin tube more accurately to lung nodules than current methods. Who can join? Adults aged 19 or older who have lung nodules that need tissue sampling and are healthy enough for the procedure. What happens? Participants will have the robotic procedure while asleep under anesthesia. The robot guides a thin tube to the lung nodule to take a small tissue sample. Participants are watched for problems and followed for 6 months. What are the risks and benefits? The new technology may be more accurate and safer than current methods. The main risks are small chance of lung collapse or bleeding, similar to regular procedures. Why is this important? This study will show if the new robotic technology works well and is safe in Korea. If successful, it could help diagnose lung cancer earlier and more accurately. This study will include 100 people at Ulsan University Hospital in Korea.

Primary outcomes include the success rate of autonomous registration and the rate of manual intervention during the process. Secondary outcomes encompass registration time, complication rates, and nodule localization success.

Collection of Lung Fluid and Tissue Samples for Research

This study will collect fluid and tissue specimens from the lungs and nose of healthy people and people with a history of lung infections. The specimens will be examined for differences between the two groups that may be associated with susceptibility to certain infections. Healthy normal volunteers and people with a history of lung infections between 18 and 75 years of age who are followed at NIH may be eligible for this study. Participants undergo the following procedures: Medical history and physical examination. Blood and urine tests. Electrocardiogram (ECG) and chest x-ray. Treadmill exercise stress test (for people over 45 years old with a history of chest pain or ECG abnormalities). Bronchoscopy: The subject s nose and throat are numbed with lidocaine and a sedative is given for comfort. A thin flexible tube called a bronchoscope is advanced through the nose or mouth into the lung airways to examine the airways carefully. Fluid collection during the bronchoscopy using one of the following methods: * Bronchoalveolar lavage: Salt water is injected through the bronchoscope into the lung and immediately suctioned out, washing off cells lining the airways. * Bronchial brushings: A brush-tipped wire enclosed in a sheath is passed through the bronchoscope and a small area of the airway tissue is gently brushed. The brush is withdrawn with some tissue adhering to it. * Endobronchial biopsies: Small pinchers on a wire are passed through the bronchoscope and about 1 to 2 millimeters of tissue is removed. * Nasal scrape: A small device is used to scrape along the inside of the nose to collect some cells. * Sputum induction * Exhaled breath condensate to obtain specimens for in vitro investigations and comparisons of both the cellular and acellular components. * Nasal nitric oxide production * Nasal potential difference * Exhaled aerosol mask sample collection * Cough aerosol collection * Exhaled particle collection * Lung Clearance Index (LCI)

The LUCENT Study - LUng Lesion Assessment Via BF-UCP190F for Central and Extended Nodal Targeting

The Olympus BF-UCP190F bronchoscope combines the reach of a thinner bronchoscope with the benefit of real-time ultrasound, enabling direct lesion visualization and sampling deeper into the lung. Following promising first-in-human data, the LUCENT study aims to evaluate the utility feasibility, effectiveness and safety of this device in a multicenter setting, generating real-world evidence to inform broader adoption in global markets.

Robotic-assisted Bronchoscopy Under Moderate Sedation With Propofol

In this study, the investigators want to find out whether robot-assisted bronchoscopy also works with moderate sedation (Propofol), as is already used in standard bronchoscopies. The study is being conducted as a pilot study. This means that it is an initial test run for a scientific investigation. The investigators are testing on a small scale whether the intervention works as predicted before a larger study is conducted.

Classification and Prediction of Difficult Awake Tracheal Intubation With Flexible Bronchoscopes

Airway management problems are key drivers for anesthesia-related adverse events. Awake tracheal intubation using flexible bronchoscopes with preserved spontaneous breathing (ATI:FB) is a recommended technique to manage difficult tracheal intubation in anesthesia, intensive care and emergency medicine. However, a prospective developed classification for this type of airway management is lacking. Due to the absence of a specifically tailored, validated classification for awake intubation with flexible bronchoscopes, many airway operators and institutions use classification tools that were originally developed for direct laryngoscopy, such as the percentage of glottic opening (POGO) score or Cormack-Lehane classification, although their diagnostic performance for the classification of ATI:FB is unknown. This prospective model development and validation study aims to develop two multivariable prediction models: a diagnostic prediction model to classify difficult ATI:FB after ATI:FB has been performed and a second prognostic prediction model to predict the risk for difficult ATI:FB before ATI:FB is performed. An additional aim is to develop a machine learning algorithm to evaluate ATI:FB.

Fasting Durations Before Bronchoscopy And The Discomfort Levels Of Patients

The goal of this clinical trial is to learn if patients feel more comfortable while being placed on contemporary fasting principle than on conventional fasting time during flexible bronchoscopy. The main questions it aims to answer are: To compare the thirty levels between patients with conventional fasting time (≥ 8 hours) and those with contemporary fasting principle (clear fluids for up to 2 hours before anesthesia) during flexible bronchoscopy To compare the levels of mucosal dryness between two groups of patients during flexible bronchoscopy To compare the levels of hunger between two groups of patients during flexible bronchoscopy To compare the levels of tiredness between two groups of patients during flexible bronchoscopy To compare the levels of fatigue between two groups of patients during flexible bronchoscopy To compare the levels of nausea/vomiting between two groups of patients during flexible bronchoscopy Participants will: Being placed on fasting either using conventional fasting time (≥ 8 hours) or with contemporary fasting principle (clear fluids for up to 2 hours before anesthesia) Being asked to respond to questions regarding thirsty, mucosal dryness, hunger, tiredness, fatigue, and nausea/vomiting in a visual analogue scale of 0 to 10

Muscle Relaxant Effect and Safety of Mivacurium Chloride and Succinylcholine for Bronchoscopy

The goal of this clinical trial is to evaluate whether mivacurium chloride and succinylcholine can provide effective and safe muscle relaxation in adult patients aged 18-60 years undergoing bronchoscopy who require muscle relaxants during anesthesia. The main questions it aims to answer are: * Is the recovery of spontaneous breathing within 15 minutes after drug discontinuation with mivacurium chloride non-inferior to succinylcholine? * How do mivacurium chloride and succinylcholine compare in terms of intraoperative hemodynamics and post-operative recovery and comfort? Researchers will compare the mivacurium chloride group and the succinylcholine group to observe if mivacurium chloride can provide similar or better recovery effects compared to succinylcholine. Participants will: * Receive either mivacurium chloride (0.14 mg/kg induction bolus + 0.5 mg/kg/h maintenance infusion) or succinylcholine (1 mg/kg induction bolus + 5 mg/kg/h maintenance infusion) as a muscle relaxant during bronchoscopy. * Have their vital signs, including blood pressure, oxygen saturation, and heart rate, monitored at multiple time points during the procedure. * Be assessed post-procedure for spontaneous breathing recovery, consciousness recovery, and time to laryngeal mask airway (LMA) removal, as well as overall comfort and satisfaction.
