Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to compare the safety and efficacy of two pharmacological sedation regimens during bronchoscopy procedures in adult patients who require elective bronchoscopy.

The main questions it aims to answer are:

* Is propofol/pethidine analgesia administered by a pulmonologist as effective and safe as midazolam/pethidine in achieving adequate sedation during bronchoscopy, particularly in terms of desaturation rate?
* Does the choice of sedative (midazolam vs. propofol) influence the occurrence of adverse events or need for escalated care?

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Bronchoscopic procedures are essential in the diagnosis and management of various respiratory diseases, but they can cause significant discomfort for patients.

Analgosedation plays a crucial role in improving patient comfort while ensuring optimal conditions for the safe performance of the procedure. However, sedation management protocols can vary greatly depending on the hospital center and the availability of an anesthetist.

Over the years, with the increasing number of bronchoscopic procedures, the growing complexity of patients-particularly those with pulmonary diseases presenting comorbidities and significant gas exchange alterations-and the limited availability of anesthetists in national hospital facilities, there has been a growing reliance on independently managed procedural sedation.

This independent management-without the need for an anesthesia specialist-has been facilitated by the use of relatively easy-to-manage drugs like midazolam, a benzodiazepine (BDZ) with a pharmacokinetic profile that makes it preferable to other similar compounds due to its rapid onset of action and the availability of an antagonist capable of reversing its effects.

However, it is important to acknowledge that the use of midazolam carries significant risks.

Propofol, compared to midazolam, is characterized by an even faster onset of action, but more importantly by higher clearance and redistribution, allowing for rapid recovery of consciousness even after prolonged infusions. Nevertheless, this drug is also associated with adverse effects, particularly on cardiac inotropic and chronotropic function as well as mean arterial pressure, thus requiring caution in its administration.

The use of propofol-as per the technical data sheet approved by the Italian Medicines Agency (AIFA)-is reserved for doctors specialized in anesthesia or those experienced in the care of intensive care patients. Pulmonologists, with their specific training in respiratory function management, possess crucial skills in administering deep sedation, such as that induced by propofol, as patient safety largely depends on proper airway management during the procedure.

The Complex Operative Unit of Pneumology and RICU (Respiratory Intensive Care Unit) at San Donato Hospital in Arezzo has extensive experience in the field of procedural analgesia.

This study is driven by the need to generate scientific evidence supporting effective and safe alternatives for analgosedation managed by pulmonologists during bronchoscopic procedures. The aim is to consolidate and expand upon preliminary studies in the literature, with the goal of ensuring optimal sedation even in the absence of anesthesia assistance.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Eligible patients may undergo flexible bronchoscopy based solely on clinical indications, with procedures classified as either interventional (e.g., laser therapy, ndotracheal/endobronchial debulking, visual biopsies, mucosal biopsies, or transbronchial biopsies guided by echo-endoscopy such as EBUS or EUS) or non-bioptic procedures, such as bronchial lavage, bronchoalveolar lavage, or endobronchial lavage. To ensure a balanced distribution of characteristics that could influence study outcomes, stratified block randomisation will be used. Patients will be stratified according to the type of bronchoscopic procedure (interventional vs simple), as the complexity and invasiveness of the procedure may influence the required depth of sedation. Within each group, block randomisation with a 1:1 ratio will be applied to ensure a consistent balance of patients recruited between treatment groups (Propofol+Pethidine or Midazolam+Pethidine).
