Q

Basic difference between CRRT and IRRT? What do you use when?

A

CRRT= Continuous Renal Replacement Therapy, done over 24 hours, and is a slow type of
dialysis

IRRT= Intermittent Renal Replacement Therapy: performed for less than 24 hours in each 24
hour period, two to seven times per week

CRRT has better haemodynamic stability (BP control) and improved survival and greater
likelihood of renal recovery.
