Q: While inserting central venous catheter (CVC), after successful obtainment of vein and free passage of wire, how big of a cut/nick should be given in skin to pass dilator to create track in subcutaneous tissues?



Answer: About 3 mm

Most post-procedure oozing at CVC  site occurs due to large scalpel cut given between passing wire and passing dilator. 3 mm cut is usually enough to pass dilator and insert CVC catheter without having post-procedure oozing.
