II. Pathophysiology
- Spontaneous endothelial bleeding does not occur until Platelet Count drops to less than 5000
III. Indications: Adults
- 
                          Platelet Count <100,000- Ocular surgery (no active bleeding)
- Neurosurgery (no active bleeding)
 
- 
                          Platelet Count <50,000- Major elective surgery (not neurosurgery)
- Invasive procedure
- Elective diagnostic Lumbar Puncture
 
- 
                          Platelet Count <20,000- Fever (over 100.4 F) in an otherwise stable, non-bleeding patient
- Central Venous Catheter Placement
 
- 
                          Platelet Count <10,000- Stable, non-bleeding patient with hypoproliferative Thrombocytopenia
 
IV. Indications: Newborns
- 
                          Platelet Count 30,000 to 50,000- Birth weight <1000 g and first week of life
- Cerebral Hemorrhage
- Coagulation Disorder
- Sepsis
- Invasive procedure
- Alloimmune neonatal Thrombocytopenia- Directed donation with washed and irradiated products
 
 
- 
                          Platelet Count 20,000 to 30,000- Active bleeding
- Lumbar Puncture
 
- 
                          Platelet Count <20,000- Stable, non-bleeding patient
