Chapter 13 Diabetic Emergencies and Allergic Reactions
Lesson Objectives • Define diabetes, differentiate between type 1 and type 2 diabetics, and know how to manage diabetes in the wilderness. • Know how to recognize and manage acute complications of diabetes, including insulin shock and ketoacidosis. • Know how to recognize and manage allergic reactions, including anaphylactic shock, allergic rhinitis, and hives.
Diabetic Emergencies (1 of 6) • Diabetes • Type 1 (insulin-dependent diabetes): Body produces little or no insulin. • Type 2: Body produces some insulin, but not enough.
Diabetic Emergencies (2 of 6) • Diabetes • Diabetics in the wilderness: • Diabetics should let group leader know of condition; discuss trip with physician, and carry adequate supplies. • Supplies include medications and equipment. • Insulin and glucagon should be protected from heat and cold.
Diabetic Emergencies (3 of 6) • Acute complications of diabetes • Insulin shock: Body gets too much insulin, too much exercise, or too little food, causing blood sugar level to fall too low. • Ketoacidosis: Body has too little insulin causing blood sugar levels to become too high. Develops more slowly than insulin shock.
Diabetic Emergencies (4 of 6) • Acute complications of diabetes • What to look for: Insulin shock • Sudden onset of pale, cold, clammy skin and rapid pulse • Headache, hunger, dizziness, nervousness, and weakness • Staggering, poor coordination, and trembling • Mood changes • Altered mental status
Diabetic Emergencies (5 of 6) • Acute complications of diabetes • What to look for: Ketoacidosis • Gradual onset of flushed, dry, warm skin and rapid pulse • Rapid, deep respirations • Extreme thirst • Fruity odor of breath • Vomiting • Frequent urination • Altered mental status
Diabetic Emergencies (6 of 6) • Acute complications of diabetes • What to do: • Check blood sugar. • Determine if victim has an injury or illness or both. • Conduct an initial check and care for immediate problems. • If blood sugar is low, inject glucagon or give glucose gel. • Evacuate those who become worse or do not recover.
Allergic Reactions (1 of 10) • Can be mild and recurrent or sudden and severe. • Anaphylactic shock: A massive allergic reaction with potentially fatal results.
Allergic Reactions (2 of 10) • Anaphylactic shock • What to look for: • Severe itching or hives • Sneezing, coughing, or wheezing • Shortness of breath • Tightness and swelling of the throat and tightness in the chest
Allergic Reactions (3 of 10) • Anaphylactic shock • What to look for: • Dramatic swelling of the face, tongue, and/or mouth • Vomiting, cramps, or diarrhea • Convulsions or loss of responsiveness
Allergic Reactions (4 of 10) • Anaphylactic shock • What to do: • Act quickly! • Check breathing and give CPR if necessary. • Administer epinephrine.
Allergic Reactions (5 of 10) • Anaphylactic shock • What to do: • Monitor condition very few minutes. • Give more epinephrine if necessary. • If you do not have epinephrine, use an asthma inhaler or nasal decongestant spray or antihistamine. • Allow conscious victims to assume a position of comfort.
Allergic Reactions (6 of 10) • Anaphylactic shock • What to do: • After victim improves, give diphenhydramine. • If there is no improvement, evacuate immediately.
Allergic Reactions (7 of 10) • Allergic rhinitis • What to look for: • Itching of the nose, roof of the mouth, throat, and eyes • Stuffy, runny nose and runny eyes • Sneezing
Allergic Reactions (8 of 10) • Allergic rhinitis • What to do: • Avoid the cause, if known. • Give antihistamines or antihistamine/decongestant combinations.
Allergic Reactions (9 of 10) • Hives • What to look for: • Pink, blotchy, itching bumps on the skin • Occasional massive, itching swelling of a lip, eyelid, hand, or foot
Allergic Reactions (10 of 10) • Hives • What to do: • Watch for signs of anaphylactic shock. • Give nonprescription antihistamines.
