19
Q

S/S of sickle cell crisis (7)

A
  • Pain
  • Fever
  • Swelling
  • Tenderness
  • Tachypnea
  • HTN
  • N/V
20
Q

Interventions for sickle cell crisis - HOP

A
  • Hydration
  • Oxygenation
  • Pain relief
21
Q

Complications of sickle cell

A
  • Autosplenectomy
  • Acute splenic sequestration crisis
22
Q

Autosplenectomy

A

Spleen fails to phagocytize foreign substances and increases the risk for infections

23
Q

Acute splenic sequestration

A

Rapid buildup of sickled RBC’s that get trapped in the spleen causing decreased blood volume, splenomegaly, hypovolemic shock

24
Q

S/S of acute splenic sequestration crisis (8)

A
  • Abdominal pain/distention
  • Weakness
  • Pallor
  • Tachycardia
  • Rapid breathing
  • Hypotension
  • Elevated reticulocyte count
  • CT showing enlarged spleen
25
Q

What clotting factor is missing in hemophilia A

A

Factor VIII

26
Q

What clotting factor is missing in hemophilia B

A

Factor IX

27
Q

Treatment for acute splenic sequestration crisis

A
  • Restore blood volume by blood transfusions and IV fluid resuscitation
28
Q

Thrombotic manifestations of DIC (10)

A
  • Cyanosis
  • Ischemic tissue necrosis
  • Abdominal pain
  • Paralytic ileus
  • Dyspnea
  • Tachypnea
  • Venous distention
  • Kidney damage
  • Delirium
  • Coma
29
Q

Labs for DIC (4)

A
  • Decreased platelets <100,000`
  • Decreased plasma fibrinogen/factor 1
  • Increased aPTT, PT, thrombin time
  • Increased fibrin degradation products
