==Background==
#REDIRECT[[Uremic bleeding syndrome]]
*Uremic toxins inhibit platelet aggregation
**Disrupts vWF
**PT/PTT normal, but bleeding time elevated
*Dialysis filter may cause thrombocytopenia
 
==Clinical Features==
 
==Differential Diagnosis==
{{Increased bleeding DDX}}
 
==Diagnosis==
==Treatment==
#Acute dialysis
#*[[pRBCs]]
#**Raising HCT to above 25-30% improves bleeding time
#*[[Desmopressin]]
#**Simplest and least toxic acute treatment
#**Increases release of factor VIII:von Willebrand factor multimers
#**0.3 mcg/kg IV (preferred) or SC (max 20mg). 3mcg/kg intranasaly is an option.
#**Onset of action ~1hr, duration of action ~4-24hr
#Estrogen
#*Unclear mechanism of action
#*Onset of action within 1d
#*Options
#**Conjugated estrogen 0.6mg/kg IV or 2.5-25mg PO daily
#[[Cryoprecipitate]]
#*Only indicated for life-threatening bleeding resistant to DDAVP and blood tranfusion
#*10 bags over 30 minutes
#[[Platelet transfusion]]
#*Minimally effective because infused platelets quickly acquire the uremic defect
#*Only use when uncontrolled hemorrhage
#Topical Hemostatic Agents
#*Gelatin - Gelfoam or Surgifoam
#*Thrombin - Floseal
