Types of hemophilia
HEMOPHILIA A/ CLASSIC
Factor Deficiency: 8/ VIII
Inheritance: X-linked Recessive
HEMOPHILIA B/ CHRISTMAS DSE
Factor Deficiency: 9/ IX
Inheritance: X-linked Recessive
HEMOPHILIA C
Factor Deficiency: 1/ XI
Inheritance: Autosomal Recessive
PARAHEMIPHILIA
Factor Deficiency: 5/V
Inheritance: Autosomal Recessive
Von Willebrand Disease
Factor Deficiency: vWF Protein (VIII:vW)
Inheritance: Autosomal Recessive
**Autosomal recessive is a pattern of inheritance characteristic of some genetic disorders
**Families with an X-linked recessive disorder often have affected males, Female are the carrier.
-Bleeding in joint spaces
-Common in children

Acidosis
GTK
No laxatives during pregnancy
✔ Mild stool softener as ordered

Urinary System
-Kidney ↑ Renal Plasma
Volume Flow: 30-50%
-Kidney size ↑
-↓ Glucose Threshold due to ↑ renal blood flow (2nd tri)
-↑urination (1st & 3rd tri)
-↑Bladder capacity (1500 ml) (2nd tri)
-↑ Diameter of ureters (2nd tri)
Musculoskeletal System
