latex allergy and hemotologic function

• antigens stijmulate t cells that release lymphokines, which cause inflamation and tissue dmg
• clinical manifestations: fever. erythema, itching
• examples: contact dermatitis, tubercuin skin test etc.

• immune complexes are deposited in tissues where they activate complement, which results in generalized inflammatory reactions
• clinical manifestations: urticaria, fever, joint paint
• examples: acute glomerulonephritis, etc

• antibodies cause activation of a complement syste, -> tissue dmg
• clinical manifestations: may include dyspnea or fever
• eamples: transfustionr eaction, ABO  incompatibility, hemolytic disease of the new born

• antibodies bind to certain cells causing rlease of chem substances that produce an inflammatory reaction
• clinical manifestation: htn, wheezing, gastro or uterine spasm, stridor, uticaria
• example: extrinsic asthma, hayfever

• Early identification of allergy
• 􀀀 Remove source of allergy from patient’s environment
• 􀀀 NURSING INTERVENTIONS: Initiate treatment forreaction which may range from redness, itching and hives to wheezing, stridor or anaphylaxis
• 􀀀 Antihistamine, epinephrine
• 􀀀 IV access, respiratory support if needed

• Iron Deficiency Anemia
• Sickle Cell Anemia
• Hemophilia
• Immune (Idiopathic) thrombocytopenia Purpura (ITP)
• Meningococcemia ( spina bifida)

Most common type of anemia – can be caused by blood loss, malabsorption, or occur during periods of rapid growth but most common cause is poor nutritional intake of iron

• poor maternal diet in pregnancy
• preemie who did not get to store iron
• starting iron-rich solid foods after 6 month
• inadequate diet at any age
• those in puberty growth spurt

• Whole-grain cereals
• Iron-fortified dry cereals

• vitamin c rich foods:
• OJ
• Citrus fruits

• Potatoes
• Some dry cereal

• Iron replacement – oral preparations
• 􀀀Teaching about color change in stool and constipation, protect teeth from discoloration
• 􀀀Oxygen therapy
• 􀀀Bed rest
• 􀀀Intravenous replacement if severe
• 􀀀Blood transfusion if severe enough

• 􀀀 Give Fe+ with Vitamin C

Caused by some situation that decreases oxygenation - surgery, high altitude, flu, asthma attack

• vaso-occlusive crisis- pain crisis
• sequestration crisis- spleen involved
• aplastic crisis
• acute chest syndrome ( box 23-3)

• pain crisis
• swollen hands

• irritability
• unusual sleepiness
• looks pale
• weakness
• fast heart beat
• big spleen
• pain on the left side of abdomen

• Acute splenic sequestration is the sudden pooling of blood in the spleen resulting in anemia, which may be life threatening.
• This type of crisis occurs most often in young children between 10 and 27 months of age in whom auto infarction of the spleens has not yet happened
• .􀀀 In its most severe form, acute splenic sequestration results in life-threatening anemia, hypovolemia, and shock. Decreases in the levels of hemoglobin <4 g per/dL are associated with 35% mortality rates. It is estimated that as much as 50% ofthe patient’s red cells can be sequestered in the spleen. Approximately 50% ofpatients who survive an episode of acute splenic sequestration will experience a recurrence.􀀀 Emergency management is aimed at restoring circulatory blood volume and hemodynamic stability. Although therapy may begin with crystalloid resuscitation, red blood cell transfusions must be given promptly.
• 􀀀 Long-term management is complicated because there is a high rate ofrecurrence of either acute or subacute sequestration. Splenectomy has been advocated when recurrent episodes occur.

• paleness
• lethargy
• "not feeling good"
• headache
• fever
• low blood count ( anemia)
• recent upper resp infection
• passing out ( fainting)

• Often diagnosed by testing cord blood of newborn
• • Need to test wider population, not just African Americans and Hispanic populations
• • Over 6 months old, Sickledex test is used for diagnosis

• Early Diagnosis – early testing for condition
• 􀀀 Prevention of crises: stay healthy and avoidprecipitating factors
• 􀀀 Hand washing to avoid colds, infections
• 􀀀 Vaccines on time
• 􀀀 Avoid stress
• 􀀀 Stay hydrated

• Pain management
• 􀀀 Hydration (to dilute sickled cells)
• 􀀀 Oxygen administration
• 􀀀 Prophylactic antibiotics at times
• 􀀀 Blood Transfusions if needed
• 􀀀 Stem Cell Transplants from identical donor if possible has been helpful
• 􀀀 Psychosocial concerns – genetic aspect of condition, achronic illness

• Every person has one of the following blood types: A, B,AB, or O. Also, every person's blood is either Rh-positive or Rh-negative. So, if you have type A blood, it's either A positive or A negative.
• 􀀀 The blood used in a transfusion must work with your bloodtype. If it doesn't, antibodies (proteins) in your blood attackthe new blood and make you sick.
• 􀀀 Type O blood is safe for almost everyone. About 40 percentof the population has type O blood. People who have this blood type are called universal donors. Type O blood is usedfor emergencies when there's no time to test a person's bloodtype.
• 􀀀 People who have type AB blood are called universal recipients. This means they can get any type of blood.
• 􀀀 If you have Rh-positive blood, you can get Rh-positive or Rh-negative blood. But if you have Rh-negative blood, you can only get RH- negative blood. SO O negative is best for emergencies ( because anyone can use this)

Blood is transfused either as whole blood (with all its parts) or, more often, as individual parts. The type of blood transfusion a patient receives depends on thesituation.

Whole blood: used to replace blood after /during a large hemorrhage

if there has been blood loss due to surgery or an injury. Also may need this type oftransfusion if you have severe anemia due to a diseaseor blood loss.

helps stop bleeding,including internal bleeding that cannot be seen. Some illnesses can prevent the body from making enough platelets or clotting factors.

Plasma is the liquid part of blood. It is mainly water, but it also contains proteins, clotting factors, hormones,vitamins, cholesterol, sugar, sodium, potassium, calcium, andmore.

If a person has been badly burned or has liver failure or a severe infection, a plasma transfusionmay be given.

• Allergic
• uticaria, flushing, wheezing, laryngeal edema
• Hemolytic
• chills, shaking, flank pain, red/black urine, N/V
• Febrile
• fever, chills
• Circulatory Overload
• precordial pain, dyspnea, rales, productive cough,distended neck veins

• -Verify blood type and Rh of donor with recipient’s type with another RN before administration
• -Warm blood
• -VS every 15 minutes for first hour
• -Administer first 20mL of volume SLOWLY and observe for reaction
• -Administer with normal saline – NO Dextrose
• -Use filter
• -Use IV pump – depends on hospital policy and type ofinfusion pump

If reaction occurs, stop blood and replacewith normal saline infusion

• A group of hereditary bleeding disorders that are caused by a deficiency in some type of clotting problem
• 􀀀 85% of people with hemophilia have Hemophilia A, adeficiency of Factor VIII(8)
• 10% have Hemophilia B, or Christmas disease and lackFactor IX(9)􀀀 These are both carried by Mom’s and given only to their sons, known as X-linked recessive traits
• 􀀀 May also be a new mutation, so there may be no family history

• Goal: prevent bleeding, provide safety
• 􀀀 Condition may be mild, moderate or severe
• 􀀀 Clinical manifestations:
• 􀀀 Spontaneous bleeding following falls, tooth eruption,epistaxis, easy bruising
• 􀀀 Hemarthrosis = bleeding into a joint, and can lead topermanent joint problems
• 􀀀 Assess for symptoms of bleeding, headache, slurredspeech, LOC, tarry stools,
• 􀀀 Promote normal development, teach First Aid
• 􀀀 Educate family, school, friends

• Clotting is the body's reaction to bleeding, & helps heal wound.
• 􀀀 The clotting factor works with platelets (small blood cell) and helps them stick together to block,or plug, cuts and wounds.
• 􀀀 With a low clotting factor, theplatelets cannot stick together,therefore the blood cannot clot;and there is continuous bleeding.
• 􀀀 Constant bleeding can lead to damaged organs, severe blood loss and even fatality (blood infusions with clotting factor may be necessary).
