Summary
Conscious sedation with diazepam improved patient tolerance during diagnostic bronchoscopy. Sedation did not increase cardiorespiratory risks, making it a safe and effective option for this procedure.
Area of Science:
- Pulmonology
- Anesthesiology
Background:
- Bronchoscopic technique lacks standardization.
- Premedication protocols, particularly the use of sedatives, remain controversial.
Purpose of the Study:
- To evaluate the safety and efficacy of conscious sedation during diagnostic bronchoscopy.
- To compare patient tolerance between a nonsedation and a sedation group.
Main Methods:
- 100 patients undergoing diagnostic bronchoscopy were randomized into two groups.
- One group received lidocaine spray and atropine sulfate i.m. (nonsedation).
- The other group received lidocaine spray, atropine i.m., and intravenous diazepam (sedation).
Main Results:
- Patient tolerance was significantly better in the sedation group.
- Six procedures could not be completed; none were in the diazepam group.
- Oxygen desaturation occurred in 17% of patients, with no increased frequency after diazepam.
Conclusions:
- Conscious sedation with diazepam demonstrated a beneficial effect on patient tolerance.
- Sedation rarely induced significant cardiorespiratory alterations during bronchoscopy.
