Q

Morphine Sulfate (Astramorph): Action?

A

Morphine is a natural opioid analgesic. Morphine also causes venous dilation and decreased venous return to the heart thus reducing myocardial oxygen demand. Morphine also causes euphoria, central nervous system depression and sedation.

A

1.Hypertension 2.Increased heart rate 3.Hallucinations 4.Delusions 5.Explicit dreams

24
Q

Ketamine (Ketalar): Notes?

A

Common street use these days in conjunction with narcotics because they potentiate each other for a longer/higher euphoria. Giving Narcan will only affect the narcotic NOT the Ketamine therefore only a minimal short-lasting effect.

25
Glucagon (Glucagen): Class?
Pancreatic hormone
26
Glucagon (Glucagen): Action?
Glucagon stimulates the liver to breakdown glycogen into glucose resulting in an increase in blood glucose. Also stimulates glucose synthesis. Glucagon also has a positive inotropic action on the heart even in the presence of beta blockade or calcium channel blockade which makes it useful for beta blocker or calcium channel blocker overdose. Glucagon also relaxes smooth muscle of the GI tract, primarily the esophagus which makes it useful for esophageal obstruction.
27
Glucagon (Glucagen): Indications? (4)
1.Hypoglycemia (when IV access is not available) 2.Beta blocker overdose 3.Calcium channel blocker overdose 4.Esophageal obstruction
28
Glucagon (Glucagen): Contraindications? (1)
Hypersensitivity (usually to proteins)
29
Glucagon (Glucagen): Onset/Duration?
Onset: 10-20 min IM, 1 min if IV Duration: 60-90 min
30
Glucagon (Glucagen): Dose/Route?
Adult: Hypoglycemia – 1 mg IM/IN may repeat in 10 min if protocol allows. Calcium channel or beta blocker overdose – 3-10 mg IV over 3-5 min followed by an infusion at 3-5 mg/hr. Peds: < 20 kg – 0.5 mg IM/IN, > 20 kg - 1.0 mg IM/IN
31
Glucagon (Glucagen): Side effects? (4)
1.Tachycardia 2.Hypotension 3.Nausea/vomiting 4.Urticaria
32
Glucagon (Glucagen): Notes?
Glucagon requires glycogen stores in the liver to increase blood glucose. If patient is malnourished glucagon may not work.
33
Haloperidol (Haldol): Class?
Antipsychotic, neuroleptic
34
Haloperidol (Haldol): Action?
Blocks dopamine type-2 receptors in the brain thereby altering mood and behavior.
35
Haloperidol (Haldol): Indications? (2)
1.Acute psychotic episodes 2.Emergency sedation of severely agitated or delirious pts
36
Haloperidol (Haldol): Contraindicaitons? (6)
1.Hypersensitivity 2.CNS depression 3.Pregnancy 4.Parkinson’s disease 5.Seizure disorder 6.Liver or cardiac disease
37
Haloperidol (Haldol): Onset/Duration?
Onset: 30-60 min IM Duration: 12-24 hrs
38
Haloperidol (Haldol): Dose/Route?
Adult: 5 mg IV or 10 mg IM, q 5-10 min, max of 15 mg. Peds: Not recommended
39
Haloperidol (Haldol): Side effects? (5)
1.Dose-related extrapyramidal reactions 2.Hypotension 3.Nausea/vomiting 4.Blurred vision 5.Drowsiness.
40
Haloperidol (Haldol): Notes?
None
41
Nitrous Oxide (Nitronox): Class?
Gaseous analgesic, anesthetic
42
Nitrous Oxide (Nitronox): Action?
Nitrous Oxide is a blended mixture of 50% nitrous oxide and 50% oxygen. When inhaled it depresses the CNS causing analgesia. Due to being administered with high oxygen concentrations it also increases oxygen tension in the blood thereby reducing hypoxia.
43
Nitrous Oxide (Nitronox): Indications? (3)
1.Traumatic musculoskeletal injury 2.Moderate to severe pain 3.Burns
44
Nitrous Oxide (Nitronox): Contraindications? (7)
1.ALOC 2.Hypotension 3.COPD 4.Chest trauma (pneumothorax) 5.Abdominal pain or injury 6.Head injury 7.Bowel obstruction.
45
Nitrous Oxide (Nitronox): Onset/Duration?
Onset: 2-5 min Duration: 2-5 min
46
Nitrous Oxide (Nitronox): Dose/Route?
Adult: Self administered by pt via held mask or mouthpiece until effects are felt Peds: Same as adult
47
Nitrous Oxide (Nitronox): Side effects? (5)
1.Altered LOC 2.Apnea 3.Dizziness 4.Nausea/vomiting 5.Malignant hypertension (rare but serious)
48
Nitrous Oxide (Nitronox): Notes?
Must be mixed 50% Nitrous Oxide and 50% Oxygen, if 100% Nitrous Oxide is administered the patient will become hypoxic and die. Pt MUST be able to follow instructions and hold mask/mouthpiece on their own to administer!
49
Thiamine (Betaxin): Class?
Vitamin (B1)
50
Thiamine (Betaxin): Action?
Thiamine is also known as vitamin B1. Thiamine combines with adenosine triphosphate to form thiamine pyrophosphate, a coenzyme necessary for carbohydrate metabolism. The brain is especially sensitive to thiamine deficiency.
51
Thiamine (Betaxin): Indications? (3)
1.Hypoglycemia with malnourishment or suspected alcoholism 2.Delirium tremors 3.Wernicke’s encephalopathy
52
Thiamine (Betaxin): Contraindicaitons?
None in the emergency prehospital setting
53
Thiamine (Betaxin): Onset/Duration?
Onset: Rapid Duration: Variable depending on degree of deficiency
54
Thiamine (Betaxin): Dose/Route?
Adult: 100 mg slow IV or IM Peds: Not recommended in the prehospital setting
55
Thiamine (Betaxin): Side effects? (4)
1.Hypotension (if given rapidly or too large a dose) 2.Nausea/vomiting 3.Anxiety 4.Diaphoresis
56
