  1. MEDICAL EMERGENCIES

  2. Medical Emergencies Defined • A situation in which the condition of the patient or sudden change in medical status requires immediate action • Head Injuries • Shock • Diabetes • Respiratory distress • Cardiac arrest • Cerebral vascular accident

  3. The Radiologic Technologist Role • Preserve life • Avoiding further harm • Obtaining further medical assistance • Knowing when assistance is warranted (most important)

  4. General Priorities • Ensure an open airway • Control bleeding • Take measures to prevent or treat shock • Attend to wounds or fractures • Provide emotional support • Continually re-evaluate and follow-up appropriately

  5. Emergency Cart • Know location and contents

  6. HEAD INJURIES • It is not the radiology technologist responsibility to diagnose, but it is useful to have basic knowledge for assessment purposes

  7. LEVELS OF CONSCIOUSNESS • Alert and conscious • Responds fully • More serious • Drowsy, but can be roused • Even more serious • does not respond to verbal commands, but can react to painful stimuli • Most Serious • Unresponsive or comatose

  8. Indications of Deteriorating Conditions • Irritability • Lethargy • Slowing pulse rate • Slowing respiratory rate

  9. Responses to Deteriorating Situations • Stop the procedure • Make sure there is an open airway • Obtain assistance • Obtain vital signs while waiting

  10. The Intoxicated Patient Inebriated vs. head injury

  11. SHOCK Failure of the circulatory system to support vital body functions

  12. Definition and Types • Hypovolemic – due to loss of blood or tissue fluid • Cardiogenic – due to a variety of cardiac disorders, including myocardial infarction • Neurogenic – due to spinal anesthesia or damage to the upper spinal cord • Vasogenic – due to sepsis, deep anesthesia, or anaphylaxis

  13. Prevention • Maintain body temperature • Avoid pain, if possible • Minimize stress and anxiety

  14. Signs and Symptoms • Restlessness • Apprehension • General anxiety • Tachycardia • Decreasing blood pressure • Cold and clammy skin • Pallor

  15. Contrast Media Reactions(Anaphylactic Shock) • Any medication can be harmful if not administered properly • Moderate to severe • As a general rule, the longer it takes for a reaction to develop, the less severe it is • Typically most severe reactions arise immediately

  16. Anaphylactoid reactions Allergic-like effects • Thought to be caused by the release of histamine • Mild • Warm sensation, metallic taste, sneezing • Moderate • Nausea, vomiting, itching • Severe • Respiratory or cardiac crisis

  17. Responses to Deteriorating Situations • Stop the procedure • Make sure there is an open airway • Obtain assistance • Obtain vital signs while waiting

  18. The role of the radiology technologist should be established in the procedures in each facility. • Very important to document condition of patient before and after event

  19. INFILTRATION or EXTRAVASATION: contrast or medication enters soft tissue instead of vein • Signs: swelling, pain, burning, redness • Cause: needle displacement • STOP EXAM IMMEDIATELY • Apply ice if <30min • Apply warm, wet compression of >30min

  20. THE DIABETIC PATIENT • NPO prep may create problem • If patient takes insulin without food, insulin production and excretion may be altered due to lack of carbohydrates • adjustment must be made immediately

  21. Hypoglycemia • A condition in which excessive insulin is present • Taking insulin without food • Depletes body’s energy and quickly leads to insulin shock Symptoms include: hungry, weak, shaky, confused, sweaty, irritable

  22. Hypoglycemia (con’t) • Solution: Carbohydrates • Glucose tablets • Orange juice sweetened w/sugar • A sugared soft drink • Candy bar, etc. • No food or drink should be given to an unconscious patient

  23. Hyperglycemia The condition of excessive sugar in the blood and is the characteristic typically associated with diabetes. • Symptoms: • Excessive thirst and urination • Dry mucosa • Rapid and deep breathing • Drowsiness and confusion

  24. Hyperglycemia (con’t) • Solution: Patient needs insulin

  25. RESPIRATORY DISTRESS AND RESPIRATORY ARREST • The Asthma Patient • Anxiety and stress of having the exam may cause reaction • The technologist role is to keep calm, as this will calm the patient • Allow patient to sit and determine if medical assistance is needed

  26. The Choking Patient • Evaluate the situation • “Can you speak?” • Clutching throat • Turning red in the face • Encourage patient to cough • Use Heimlich maneuver if necessary

  27. CARDIAC ARREST • Signs and Symptoms • Crushing chest pain that may or may not radiate down the left arm

  28. CPR (Cardiopulmonary Resuscitation) • Alert the proper personnel before beginning • Cerebral function is generally impaired if the brain is deprived of oxygen for more than 4 to 6 minutes

  29. 3 Primary Aspects of CPR • ABC’s • Airway • Breathing • Circulation

  30. Considerations • DNR request Once begun, basic life support should (and for legal reasons, must) be continued until the victim resumes spontaneous respiration and circulation, a physician or other responsible health care professional calls a halt, or the rescuer is too exhausted to continue.

  31. Cerebrovascular Accident • Stroke • Onset could be sudden or gradual • Paralysis • Slurred speech • Dizziness • Vission loss • Loss of consciousness

  32. Minor Medical Emergencies • Nausea and vomiting • Epistaxis • Vertigo and syncope • Seizures • Falls

  33. Nausea and Vomiting • Breath slowly and deeply • Turn head to side and give patient emesis basin

  34. Epistaxis • Defined: nosebleed • Lean forward, pinch nostril (do not lean back) • If not effective within 15 minutes, get help

  35. Vertigo and Syncope • Vertigo: dizziness • Allow patient to sit or lie down • Syncope: fainting • Temporary lack of blood flow to brain • Allow patient to lie down with feet elevated, loosen clothing

  36. Seizures • Mild to severe • Slight confusion or weakness, body trembling and drooling • Exam should be postponed • Protect patient with pillows, clear airway and summon help

  37. Falls • Attempt should be made to minimize impact when possible and then proceed to get assistance

  38. Wounds • Hemorrhage: note condition, if bleeding, apply pressure; if extremity, place above heart if possible • Burns: maintain sterile precautions, be extra gentle with patient • Wound dehiscence: uncommon; a patients sutures come apart and abdominal contents spill out

  39. SUMMARY Be alert and aware that emergencies do happen in the radiology department. Respond in a calm and confident manner.
