    Study Notes

    Heparin Induced Thrombocytopenia (HIT)

    • Heparin induced thrombocytopenia (HIT) occurs when the body's immune system reacts to the presence of heparin, leading to a low platelet count.

    Anticoagulation Agents

    • Low-Molecular-Weight Heparin (LMWH) is used to prevent and treat blood clots.
    • Fondaparinux (Arixtra) is a type of anticoagulant that inhibits the formation of blood clots.
    • Oral anticoagulants, such as warfarin (Coumadin), are used to prevent and treat blood clots.
    • The antidote for warfarin (Coumadin) is vitamin K.

    Blood Work

    • International Normalized Ratio (INR) is a test used to measure the effectiveness of warfarin (Coumadin) therapy.
    • Activated partial prothrombin time (aPTT) is a test used to measure the effectiveness of heparin therapy.
    • Prothrombin time (PT) is a test used to measure the blood's clotting ability.
    • Platelet count is a test used to measure the number of platelets in the blood.
    • Hemoglobin (HGB) and hematocrit (HCT) are tests used to measure the amount of red blood cells in the blood.

    Anticoagulation Therapy Monitoring

    • INR and aPTT are used to monitor the effectiveness of anticoagulant therapy.
    • Platelet count is used to monitor for thrombocytopenia (low platelet count).
    • Bleeding is a complication of anticoagulation therapy.
    • Numerous drug interactions can occur with anticoagulation therapy.

    Thrombocytopenia

    • Thrombocytopenia is a decrease in platelets, which can lead to bleeding.
    • Platelet count is used to diagnose thrombocytopenia.

    Anticoagulation Therapy Management

    • Anticoagulation therapy is used to prevent and treat blood clots.
    • Numerous drug interactions can occur with anticoagulation therapy.
    • Bleeding is a complication of anticoagulation therapy.

    Pulmonary Embolism (PE)

    • PE occurs when a blood clot travels to the lungs and blocks an artery.
    • PE risk factors include immobility, cancer, and surgery.
    • Signs and symptoms of PE include chest pain, shortness of breath, and coughing.
    • Diagnostic tests for PE include D-dimer, CT scan, and ventilation/perfusion scan.
    • Interventions for PE include anticoagulation therapy, thrombolytic therapy, and surgery.

    Hemorrhage

    • Hemorrhage is a loss of a large amount of blood externally or internally in a short period of time.
    • Classification of hemorrhage includes type of vessel and visibility.
    • WHO grading system is used to measure bleeding.
    • Signs and symptoms of hemorrhage include tachycardia, hypotension, and tachypnea.

    Pain Assessment

    • Pain assessment tools include visual analog, FACES, and numerical rating scales.
    • Affective responses to pain include anxiety, fear, and depression.
    • Behavioral responses to pain include changes in sleep, appetite, and activity.
    • Physiological responses to pain include increased heart rate, blood pressure, and respiratory rate.

    Pharmacological Pain Management

    • Non-opioid analgesics, such as acetaminophen and NSAIDs, are used to treat mild to moderate pain.
    • Opioids, such as morphine and codeine, are used to treat moderate to severe pain.
    • Adjuvants, such as antidepressants and anti-inflammatories, are used to treat pain.
    • Routes of administration for pain medications include oral, intravenous, and epidural.

    Opioids

    • Tolerance, physical dependence, and addiction are risks associated with opioid use.
    • Patient-controlled analgesia (PCA) is a method of pain management that allows patients to self-administer pain medication.
    • Epidural analgesia is a method of pain management that involves injecting pain medication into the epidural space.

    Non-Pharmacological Pain Therapy

    • Non-pharmacological approaches to pain management include relaxation, distraction, and guided imagery.
    • Complementary or alternative therapies, such as biofeedback, therapeutic touch, and reiki, can be used to manage pain.
    • Collaboration with patients and families is necessary in making pain management decisions.

    Heparin Induced Thrombocytopenia (HIT)

    • Low platelet count due to heparin use
    • Risk of thrombosis and bleeding

    Anticoagulation Agents

    • Low-Molecular-Weight Heparin (LMWH)

    • Hematocrit (HCT): 0.4-0.51 (male), 0.34-0.48 (female)

    Anticoagulation Therapy Monitoring

    • Monitor INR, aPTT, PT, and platelet count
    • Monitor for bleeding and thrombosis

    Bleeding

    • Monitor for signs of bleeding (e.g. tachycardia, hypotension, petechiae)
    • Manage bleeding with fluid replacement, blood transfusion, and surgical intervention

    Thrombocytopenia

    • Decreased platelet count
    • Monitor for signs of bleeding

    Anticoagulation Therapy Management

    • Manage anticoagulation therapy to prevent bleeding and thrombosis
    • Monitor for signs of bleeding and thrombosis
