Apr 15, 2025

Chapter 20: Endocrine and Hematologic Emergencies

Overview

  • Focuses on understanding endocrine and hematologic emergencies
  • Key conditions: Diabetes (Type 1 & 2), Sickle Cell Disease, Clotting Disorders, and related complications
  • Pre-hospital assessment and treatment strategies for diabetic emergencies
  • Discussion of hematologic emergencies including Sickle Cell Disease, Hemophilia, Thrombophilia, and Deep Vein Thrombosis (DVT)

Endocrine System

  • Function: Controls body functions through hormone secretion
  • Endocrine Disorders: Result from communication problems within the body
    • Hypersecretion: Excess hormone production
    • Hyposecretion: Insufficient hormone production
    • Receptor Issues: Target organs not responding to hormones

Glucose Metabolism

  • Brain requires glucose and oxygen to function
  • Insulin: Key for glucose entry into cells
  • Pancreas: Produces insulin and glucagon
    • Alpha Cells: Produce glucagon
    • Beta Cells: Produce insulin

Diabetes Mellitus

  • Type 1 Diabetes: Autoimmune destruction of beta cells, requires external insulin
  • Type 2 Diabetes: Insulin resistance, managed with medications and lifestyle changes
  • Gestational Diabetes: Occurs during pregnancy

Complications of Diabetes

  • Hypoglycemia: Low blood sugar, life-threatening if untreated
    • Signs: Altered mental status, rapid pulse, pale skin
  • Hyperglycemia: High blood sugar, can lead to DKA or HHNS
    • Symptoms: Thirst, frequent urination, nausea, fruity breath

Diabetic Emergencies

  • Diabetic Ketoacidosis (DKA): Life-threatening, needs rapid recognition and treatment
  • Hyperosmolar Hyperglycemic Nonketotic Syndrome (HHNS): High blood sugar without ketosis, leads to severe dehydration

Hematologic Emergencies

  • Components of Blood: Red blood cells, white blood cells, platelets, plasma
  • Sickle Cell Disease: Genetic disorder causing misshapen red blood cells
    • Leads to pain crises and increased infection risk
    • Symptoms: Anemia, gallstones, spleen dysfunction

Clotting Disorders

  • Hemophilia: Decreased ability to clot, risk of life-threatening bleeding
  • Thrombophilia: Blood clots more easily than normal, risk for DVT and pulmonary embolisms

Deep Vein Thrombosis (DVT)

  • Common in sedentary individuals or post-surgery
  • Treatment: Anticoagulation therapy, compression stockings

Patient Assessment

  • Scene Size-up: Look for indications of diabetic supplies
  • Primary Assessment: Check ABCs, level of consciousness, and transport decision
  • History Taking: Gather information on insulin use, dietary intake, and recent activity
  • Secondary Assessment: Focus on neurological status and vital signs

Emergency Care

  • For Diabetic Emergencies:

    • Administer glucose for hypoglycemia if patient is conscious
    • Rapid transport for unresponsive patients
    • Monitor and manage airway, breathing, and circulation
  • For Hematologic Emergencies:

    • Provide supportive care: oxygen, comfort, and rapid transport

Review Questions

  • Address topics like glucose utilization impairment in Type 1 diabetes, causes of hypoglycemic crisis, and the importance of maintaining proper glucose levels.
