Study Notes
Basic Principles of Management in a Medical Emergency
- Effective management is crucial in medical emergencies to ensure patient safety and proper care.
Signs, Symptoms, and General Management of Selected Medical Emergencies
External Bleeding/Lacerations
- Immediate pressure should be applied to control bleeding.
Shock
- Defined as a failure of the cardiovascular system to maintain blood pressure, leading to reduced oxygen (Oâ‚‚) delivery to tissues.
- Caused by low circulating blood volume.
- Four types of shock include hypovolemic, cardiogenic, distributive, and obstructive.
Orthostatic (Postural) Hypotension
- Occurs when blood pressure drops upon standing after being in a sitting or lying position.
- Blood pooling in lower extremities reduces venous return, affecting cardiac output and brain perfusion.
- Symptoms: dizziness, lightheadedness, nausea, cold sweats, and potential fainting.
Fractures
- Need immediate immobilization and stabilization.
Burns
- Management focuses on preventing wound contamination, reducing pain, and preventing shock.
Seizures
- Protect the individual from injury during the seizure; maintain the patient's modesty and privacy.
Choking
- Administer CPR and perform the Heimlich maneuver if necessary.
Autonomic Dysreflexia
- An exaggerated reflex of the sympathetic nervous system in response to noxious stimuli.
Cardiac Arrest/Myocardial Infarction (MI)
- Results from decreased blood flow and oxygen to heart muscle due to coronary artery obstruction, causing tissue death.
- For conscious patients: position comfortably, loosen tight clothing, monitor breathing, provide oxygen if available, and call 911.
- For unconscious patients: follow CAB (Circulation, Airway, Breathing) and call 911 before starting CPR.
Stroke (Cerebrovascular Accident, CVA)
- Urgency in treatment; early recognition is critical.
- If ischemic stroke occurs and TPA is administered within 3 hours, severity of deficits can be minimized.
- Public awareness campaigns promote using "brain attack" to encourage quick emergency response.
Internal Bleeding
- Typically caused by trauma; requires immediate medical attention.
Diabetes Mellitus (DM)
- Characterized by chronic hyperglycemia and metabolic disruption of carbohydrates, fats, and proteins.
- Insulin regulation issues lead to long-term damage to vital organs and systems.
- Two main types:
- Type I (Insulin-Dependent Diabetes Mellitus): No insulin production; requires injections.
- Type II (Non-Insulin-Dependent Diabetes Mellitus): Body's ineffective use of insulin; managed through diet, exercise, and sometimes oral medications.
Hypoglycemia
- Low blood sugar levels can be life-threatening; immediate intervention is needed.
Hyperglycemia
- High blood sugar levels may lead to diabetic coma; requires monitoring and management.
Dehydration
- Results from excessive water loss or inadequate intake, leading to hypovolemia and potential shock if untreated.
