Anesthesia vs Sedation for Lung Lesions
(RESSOURCE Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores two methods for performing an endoscopic procedure called pEBUS (Peripheral Endobronchial Ultrasound) to examine lung lesions. It compares the effectiveness of general anesthesia versus conscious sedation in achieving better diagnostic results. The trial focuses on patients with lung lesions smaller than 5 cm that are not visible with regular light during a scan. Patients who have already chosen pEBUS with their doctor for their lung lesion may be suitable candidates. As an unphased trial, this study provides patients the opportunity to contribute to medical knowledge and potentially enhance diagnostic methods for lung lesions.
Do I need to stop my current medications for this trial?
The trial information does not specify whether you need to stop taking your current medications.
What prior data suggests that these anesthesia and sedation methods are safe for endoscopic investigation of lung lesions?
Research has shown that both conscious sedation and general anesthesia are generally safe for endoscopic procedures like peripheral EBUS, a technique to examine the lungs.
Studies have found that conscious sedation for peripheral EBUS is safe, with few complications, and patients generally tolerate it well. One study reported that radial-probe EBUS, a specific type of endoscopic ultrasound, had a low rate of complications, making it a reliable option for diagnosing lung issues.
Research also supports the safety of general anesthesia during peripheral EBUS. Studies report low rates of minor complications, such as slight bleeding and low oxygen levels, which usually don't require further medical attention. Another study confirmed that this approach is both effective and low-risk.
In summary, studies indicate that both conscious sedation and general anesthesia for peripheral EBUS are safe and well-tolerated.12345Why are researchers excited about this trial?
Researchers are excited about this trial because it explores whether conscious sedation or general anesthesia is better for performing Peripheral EBUS (Endobronchial Ultrasound) on lung lesions. Conscious sedation allows patients to breathe on their own and be more aware during the procedure, potentially reducing recovery time and the risks associated with deep anesthesia. On the other hand, general anesthesia ensures the patient is completely unconscious, which might lead to more precise control during the procedure. By comparing these two approaches, the trial aims to find out which method offers the best balance of effectiveness and safety for patients with lung lesions.
What evidence suggests that this trial's treatments could be effective for investigating lung lesions?
This trial will compare two methods of performing peripheral endobronchial ultrasound (EBUS) for diagnosing lung problems: one under conscious sedation and the other under general anesthesia. Studies have shown that EBUS with the patient awake but relaxed (conscious sedation) can achieve success rates as high as 88% in some cases. Meanwhile, research indicates that EBUS while the patient is fully asleep (general anesthesia) can achieve similar success rates, around 87% to 88%, especially in certain patient groups. Both methods are considered safe and effective, with studies suggesting they are equally good at diagnosing lung issues. The choice between being awake or asleep during the procedure often depends on patient comfort and available resources, as both methods have shown promising results in diagnosing lung conditions.14678
Are You a Good Fit for This Trial?
This trial is for individuals with lung lesions, potentially due to cancer. Participants should be suitable for a procedure called peripheral endobronchial ultrasound (pEBUS), which can be done under either conscious sedation or general anesthesia.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- Peripheral EBUS under Conscious Sedation

Trial Overview
The study aims to compare the effectiveness of pEBUS when performed under two different conditions: conscious sedation and general anesthesia. The goal is to determine which method provides better diagnostic results and patient comfort.

Experimental Treatment
In the general anesthesia group, an endotracheal tube larger than 7 will be used. The patient will be kept non-arousable to non-nociceptive stimulation (RAS = -5) by a perfusion including, at the anesthesiologist's discretion: fentanyl, sufentanyl, remifentanyl, midazolam or propofol. The sedation of this group will not be protocolized given the wide variety of practices in the participating centers, but the targeted level of sedation will be and the medication administered will be adjusted according to this target. The RAS will be evaluated every 5 minutes, or earlier if signs of arousal are present, to ensure that the intended target is maintained and adjustments to the rate of infusions as well as boluses may be made/administered by the anesthesiologist to maintain the targeted level of sedation. Patients may be paralyzed at the discretion of the anesthesiologit. The ventilatory parameters will be standardized according to the VESPA protocol
In the conscious sedation group, the procedure will be performed through the nose or mouth at the discretion of the endoscopist. The patient will remain breathing spontaneously throughout the procedure and will be administered oxygen through a nasal cannula at an initial flow rate of 2L/min. A combination of propofol, fentanyl and midazolam boluses will be used to maintain moderate sedation. At IUCPQ-UL, fentanyl and midazolam will be used as in our routine practice. The boluses will be prescribed by a doctor experienced in conscious sedation (anesthesiologist, intensivist or pulmonologist) according to the patient's state of wakefulness assessed by the Richmond Agitation-Sedation Scale (RAS) .Centers will decide, prior to initiating recruitment locally, the drug combination used to sedate patients and they will maintain the use of the same drug combination throughout the study.
