MOA for Acetaminophen

A

It inhibits the synthesis of Prostaglandins in the CNS blocking the generation of pain impulses.

Q

Dextrose in Water MOA

A
  1. increase blood sugar to normal in hypoglycemia
  2. Hypertonic solution producing a transient movement of water from interstitial spaces into the venous system (osmotic diuretic)

Q

Indications for dextrose in water

Study These Flashcards
A
  1. severe hypoglycemia
  2. Head injury with symptomatic hypoglycemia (half dose)
  3. Stroke with symptomatic hypoglycemia (half dose)
22
Q

Contraindications for dextrose in water

Study These Flashcards
A
  1. allergy to corn
  2. hyperglycemia
  3. hypersensitivity to dextrose solution
  4. relative contraindications- intracranial hemorrhage (half dose)
23
Q

Adult dosage for dextrose in water (3)

Study These Flashcards
A
  1. 25g D50W SIVP/IO q 5 min prn, titrate to BGL >/= 4.0 mmol/L or PT improvement to max 50g
  2. Suspected stroke: 12.5g D50W SIVP/IO q 5 min prn, titrate to BGL = 3.0mmol/l or PT improvement to max 50g
  3. suspected head injury: 12.5g D50W SIVP/IO q 5min prn, titrate to BGL = 4.0mmol/L or PT improvement max 50g
24
Q

side effects of dextrose in water (4)

Study These Flashcards
A
  1. rebound hyperglycemia
  2. May aggravate hypertension and CHF
  3. may cause neurological symptoms in alcoholic PT
  4. Wernicke’s encephalopathy/ Korsakoff’s syndrome
25
Ems considerations for dextrose in water
1. Tissue necrosis if infiltration occurs, to avoid: a. Give ½ the total volume and check IV patency before giving the rest 2. Utilize a large bore catheter in a large vein 3. D50W has a short duration of action, therefore follow drug administration with an oral complex carbohydrate (ie: toast, crackers, pasta, sandwich) 4. May precipitate severe neurological symptoms in alcoholics; give thiamine prior to D50W (ACP only) **Severe thiamine deficiency can reduce glucose utilization by half and may precipitate: 1. Wernicke’s Encephalopathy: is an acute and reversible disorder as a result of lack of thiamine associated with chronic alcoholism. It is characterized by poor voluntary muscle coordination, eye muscle weakness and mental derangement 9 2. Korsakoff’s Syndrome: is a frequent result of severe deficiency of vitamin B1(thiamine) resulting in significant memory loss and can be irreversible, Wernicke’s usually precedes Korsakoff’s 5. Increased intracellular glucose levels in the setting of cerebral ischemia and hypoxia result in increased intracellular acidosis due to anaerobic metabolism of glucose and subsequent neuronal death
26
dimenhydrinate
Gravol
27
Classification for dimenhydrinate
Antiemetic
28
MOA for dimenhydrinate (2)
1. Depresses vestibular (equilibrium) function by inhibiting histamine H1 receptors 2. Sedative effects due to inhibition of histamine
29
Indications for dimenhydrinate
Nausea and Vomiting associated with motion sickness and vertigo, pregnancy, narcotic admin and alcohol withdrawal.
30
Contraindications for dimenhydrinate (3)
1. Hypersensitivity to dimenhydrinate and diphenhydramine or propylene glycol (food additive) 2. Narrow angle glaucoma 3. Patients who have ingested large quantities of depressants including alcohol
31
Dosage for dimenhydrinate (2)
50mg SIVP/IM/IO q 4hrs Half dose and do not repeat in PT over 65 yrs
32
side effects for dimenhydrinate (2)
1. drowsiness 2. sedative effect
33
dimenhydrinate considerations (2)
1. 10ml syringe with NS for IV administration; lessens vein irritation 2. preferred antiemetic for nausea and vomiting associated with vertigo, motion sickness or narcotic side effect
34
diphenhydramine
benadryl
35
classification of diphenhydramine
antihistamine
36
MOA of diphenhydramine
1. Competes with histamine for H1 receptor sites on effector cells. They thereby prevent, but do not reverse responses mediated by histamine alone 2. Does not inhibit histamine release
37
indications for diphenhydramine
1. Allergic reactions 2. Adjunct to epinephrine (used after epinephrine deployed) in the management of anaphylaxis 3. Management of drug induced extrapyramidal symptoms
38
Contradictions for diphenhydramine
1. Hypersensitivity to either diphenhydramine or dimenhydrinate 2. Relative : avoid antihistamine in nursing mothers and/or in neonates (less than 28 days) unless life threatening anaphylaxis/allergy
39
diphenhydramine dosage
ADULT: (ELIXIR) 50mg PO - Do not repeat dose Or 1mg/kg IM/SIVP/IO, single max dose 50mg - Do not repeat dose (use vastus lateralis for IM injection) PEDIATRIC: (ELIXIR) 1mg/kg PO, single max dose of 50 mg – Do not repeat dose Or 1mg/kg SIVP/IM/IO, single max dose 50mg - Do not repeat dose (use vastus lateralis for IM injection)
40
Side effects of diphenhydramine (5)
1. Dry mouth 2. Blurred vision 3. Hypotension 4. Thickening of bronchial secretions 5. bronchospasm
41
EPINEPHRINE 1mg/mL
Adrenalin
42
classification of epinephrine
sympathomimetic; endogenous catecholamine
43
MOA for epinephrine (4)
1. Inhibits the release of histamine associated with allergic and anaphylactic reactions. 2. Alpha 1 agonist- a. Peripheral vasoconstriction improving coronary and cerebral perfusion 3. Beta 1 agonist- a. Positive chronotropic, inotropic, and dromotropic properties b. Increases automaticity in the heart 4. Beta 2 agonist- a. Bronchodilation - adrenergic receptors in the lungs to relax bronchial smooth muscle
44
indications for epinephrine
anaphylaxis
45
contraindications for epinephrine
none in an emergent situation
46
dosage for epinephrine
0.3mg IM q5 prn, max 0.9mg
47
side effects for epinephrine (8)
1. Palpitation 2. Tremors 3. Nervousness 4. Dizziness 5. Anxiety 6. Headache 7. Hypertension 8. Tachycardia
48
Considerations for epinephrine (5)
1. All patients receiving this medication MUST be cardiac monitored (12 Lead) 2. DO NOT administer 1mg/mL (1:1,000) solution by direct IV 3. Epinephrine in pregnancy can cause fetal hypoxia 4. Ensure the patient is in a recumbent position prior to administration of epinephrine 5. The concentration of 1 mg/mL was previously known at 1:1000
