14
Q
CASE STUDY
- A 63 year old male is receiving an injection for a nail procedure
- The patient is very anxious and becomes light headed during the injection
- Post-injection, the patient states he is having difficulty breathing and his chest feels tight
A
- The patient could be anxious and having a panic attack, could be having an asthmatic attack, but anaphylaxis would be the most likely cause ***
- You should assume this is anaphylaxis and give epinephrine
- The epinephrine is not going to hurt them even if they are not actually experiencing anaphylaxis, so you should give it and monitor for whether or not it resolves the problem
15
Q
Acute asthmatic attack
A
- Asthma: A lung disease that is characterized by inflammation, obstruction, that is reversible
- Acute attack may be triggered by various stimuli: (aspirin, NSAIDs, pollen, mold, dirt, smoke, perfumes, paints, animal dander, etc.)
16
Q
Pathophysiology of acute asthmatic attack
A
- Spasm of the smooth muscle
- Edema of the airway

A
- Dyspnea
- Wheezing (inspiratory & expiratory)
- Patient prefers to sit upright and lean forward
- Cyanosis
- Difficulty talking
- Lethargy and confusion
18
Q

20
Q
Seizures
A
- Convulsive disorders characterized by abrupt transient symptoms of motor, sensory, psychic or autonomic nature frequently associated with change in consciousness (usually related to pre-existing epilepsy or drug toxicity).
21

- Monitor Airway
- Reassurance as patient comes out of seizure for status epilepticus
- Valium 10-15 mg every 10-20min.
- Dilantin 4 mg/kg IV
23
Q
CASE STUDY
- A 23 year old female has consented for an injection with lidocaine
- During the injection, patient states she is getting light headed and loses consciousness
- Patient is having additional symptoms which are consistent with convulsions
A
- Typically, if someone is having a reaction to the injection, it is typically IV and not in the soft tissues, so it is not likely the result from the injection
- We would consider syncope and seizures on our differential
- The patient experienced seizures for 30 seconds to 1 minute while going in and out of consciousness
- Need to secure the patient, maintain an airway and clear the area of potential hazards
24
Q
Hypertensive crisis
A
- Acute rise in blood pressure
- BP of 180/110 mm Hg
25
Signs and symptoms of hypertensive crisis
- Stroke
- Angina/ heart attack
- Loss of consciousness/ memory loss
- Pulmonary edema
- Visual loss
- Kidney damage
26
Treatment of hypertensive crisis
- Goal is to lower diastolic to 90-100mm Hg over 15 min.
- Supportive
- Nifedipine(procardia) 10mg SL
- Amlodipine(norvasc) 10mg
- Sit at 45 degree angle
- Treatment will also be dependent upon etiology (neurological, cardio-vascular, renal)
27
CASE STUDY
- A 57 year old diabetic male is electing to have a surgical procedure
- Prior to the injection, the patient’s blood pressure rises to 190/110
- Need to give nifedipine or amlodipine and recline the patient back to 45 degrees
- Monitor the blood pressure over the next 10 to 20 minutes until the blood pressure is stabilized
- Give 10 mg nifedipine, monitor, give another 10 mg if needed
28
Insulin shock
- Hypoglycemia secondary to either too much insulin or insulin taken without food
29
Signs and symptoms of insulin shock
- Weakness, faintness
- Hunger
- Fast pulse
- Sweating
- Convulsions
- Irritability
- Moist skin
- Confusion
- Coma
30
Treatment of insulin shock
Conscious - able to swallow
o Give oral sugar and/or orange juice
Unconscious
o Start IV 20-50 ml of D50 slowly
o 1 mg glucagon IM
31
CASE STUDY
- A 62 year old female presents for high risk foot care
- During the evaluation patient states she has not eaten and her blood sugars are dropping and she is not feeling well
- You are able to give the patient some oral glucose, but the patient still has episodes where she is in and out of consciousness
- Need to keep the patient safe because she was going in and out of consciousness
- They monitored glucose with finger sticks, to get the patient’s blood sugar up to 110
- Needed to have someone pick her up and take her home to avoid another blood sugar drop while she was driving
- If you do not know if the patient has a low blood sugar and you do not have the means to check the blood sugar, but they seem to be having the symptoms of hypoglycemia, always give them glucose as a prophylaxis because glucose will not harm them
32
CASE STUDY
- A 38 year old IDDM male is being evaluated for chronic ulcers
- Patient reports nausea, abdominal pain, polydipsia, tachycardia, dehydration, ketosis
- Diagnosis is diabetic ketoacidosis, so you call 911 and initially check blood sugar
- The first step in management in the hospital is IV fluids and oxygen
33
Local anesthetic toxic reaction
Lidocaine toxicity
34
Symptoms of lidocaine toxicity - pulmonary
o Increased/irregular respiration
| o Respiratory Arrest
35
Symptoms of lidocaine toxicity - neurological
```
o Paresthesias
o Nervousness
o Depression
o Blurred vision
o Tinnitus
o Convulsions
o Coma
```
36
Symptoms of lidocaine toxicity - neurological
o Arrythmia
o Hypotension
o Cardiac arrest
37
Treatment of lidocaine toxicity
- Mental changes (observe)
- Hypotension: vasopressors
- Respiratory depression: (o2), ephedrine SO4
- Convulsions: Valium 5-10 mg IV or 25 mg IM
38
Signs and symptoms of epinephrine reaction
- Neurological: Headache, seizure, restlessness, agitation, nervousness
- Cardiovascular: Tachycardia, palpitations
- Nausea, vomiting, SOB, weakness
39
Treatment of epinephrine reaction
- Thorazine 0-5 mg-1.0 mg IV
| - Demerol 12.5 mg-25 mg IV
40
CASE STUDY
- A 29 year old male consents to a lidocaine injection for the management of an ingrown toenail
- During the injection the patient states the room is getting dark and closing in on him
- Make sure the patient is safe so they don’t get hurt
- If they are sliding off the chair, you can assist them down to the floor, but they are going to be heavier than you expect
41
Diabetic ketoacidosis
- Occurs when the blood sugar becomes too high, either because the insulin dose was too small or because it was neglected altogether
42
Signs and symptoms of diabetic ketoacidosis
- Polyuria (excess urine output) because of osmotic diuresis
- Polydipsia (excessive thirst) because of dehydration
- Polyphagia (excessive eating), probably related to inefficient utilization of nutrients
- Nausea and vomiting, the latter worsening dehydration
- Tachycardia, reflecting dehydration
- Deep, rapid respirations (KUSSMAUL’S RESPIRATION), in an attempt to blow off excess acids by CO2 elimination
- Warm, dry skin and dry mucous membranes, also reflecting dehydration
- Fruity odor on the breath
- Sometimes fever, abdominal pain, and falling blood pressure
43
Treatment of diabetic ketoacidosis
- Follow the procedure for any comatose patient with regard to AIRWAY maintenance and oxygen. Be alert for vomiting, and have suction ready.
- Start an IV LIFELINE, draw blood for laboratory tests, and infuse a liter of normal saline at the rate ordered by the physician. The patient in ketoacidosis is severely dehydrated, often to the point of shock, and needs volume.
- MONITOR cardiac rhythm. Changes in serum potassium caused by acidosis can lead to marked cardiac instability. Note the contour of the T waves on the rhythm strip. If they are sharply peaked, the patient’s potassium level may be dangerously high, and the physician may wish to order bicarbonate.
44
***Two general rules to remember about emergency treatment of diabetics***
- Any patient in coma of unknown etiology should receive glucose
- Diabetics have trouble with hyperglycemia and hypoglycemia. When in doubt, give glucose. One will not harm a hyperglycemic patient by giving glucose (the amount administered is trivial compared to what he/she already has in his blood), but one may save the life of a hypoglycemic patient by this treatment.
45
- You have just given a plantar fascitis injection (0.05% marcaine: 40 mg/ml Kenalog). Patient is developing a pruritic rash on the affected foot and lower leg 15 minutes post-injection. What is the most appropriate treatment?
o 1:100,000 IM injection of epinephrine (local anesthetic)
o 1:1,000 IM injection of epinephrine (systemic effects)
o 50 mg Benadryl PO
o 250 mg of aminophylline
o Emergent I&D
50 mg Benadryl PO
The most likely cause of the allergic reaction is the preservatives in the injection
