This is a life-threatening complication that can rapidly progress to cardiac tamponade. It requires emergent hemodialysis or peritoneal dialysis to remove uremic toxins. Lab values like elevated BUN or creatinine are expected in CKD and do not mandate immediate intervention by themselves.
Do not delay intervention for a friction rub; it signifies serosal inflammation from uremia. Monitor for pulsus paradoxus and muffled heart sounds as signs of impending tamponade.
