Who it lists and where
Who the trial lists, as registered
Lists people 18 and older. Conditions: Coronary Artery Disease; Coronary Angiography; Vascular Access Site Complications.
Patients aged 18 years and older scheduled for femoral coronary angiography (CAG) and/or percutaneous coronary intervention (PCI)
Patients undergoing a single femoral arterial access procedure
Patients with sheath size typically 5-Fr, 6-Fr, or 7-Fr

1 more inclusion criterion and the exclusion criteria are on the listing.
The aim of this study is to compare bleeding outcomes, pain, comfort levels, sleep quality, and associated factors among patients receiving a chitosan-based hemostatic pad versus a sandbag following femoral coronary angiography (CAG) and percutaneous coronary intervention (PCI). Femoral coronary angiography (CAG) and percutaneous coronary intervention (PCI) are widely performed procedures for the diagnosis and treatment of coronary artery disease (CAD), which remains the leading cause of mortality worldwide (Batmaz \& Cengiz, 2023; Wardiyana et al., 2024). The full summary is on the listing.

1 more inclusion criterion and the exclusion criteria are on the listing.
The goal of this clinical trial is to learn which of three common root-canal rinsing (irrigation) methods removes bacteria most effectively in adult patients who need root-canal treatment. The main questions it will answer are: How much does a chitosan solution used alone lower the number of bacteria inside the root canal? Do the combinations sodium hypochlorite + chitosan or sodium hypochlorite + EDTA lower bacteria even more than chitosan alone? Researchers will compare the three irrigation methods to see which one achieves the greatest bacterial reduction. The full summary is on the listing.
