Diazapam (Valium): Dosage
5-15 mg IV
lorazepam (Ativan): interactions
Effects are additive when used with other CNS depressants, for example, alcohol
Morphine Sulfate: Notes
Patients with allergy to sulfa are not allergic to MS. Morphine is the standard which all other analgesics are compared. 60 mg oral MS is same as 10 mg IV MS. MS is a schedule II narcotic.
Lorazepam (Ativan): class
benzodiazepine, anticonvulsant, sedative, hypnotic
Naloxone Hydrochloride: Pharmacokinetics
Onset: 1-2 minutes IV, 2-5 minutes IM.
Lorazepam (Ativan): Indications
Major motor seizures, premedication for cardioversion ot TCP, sedation associated with intubation, muscle spasms, acute anxiety, agitation (amphetamine or cocaine OD)
Lorazapam (Ativan): pharmacokinetics
Onset: 1-2 min IV; 15 min IM
Duration: 30-60 min IV, IM
midazolam (Versed): interactions
Effects are additive when used with other CNS depressants, for example, alcohol.
Morphine Sulfate: Indications
Pain, cardiac pain refractory to NTG, burns, acute pulmonary edema.
Dopamine: precautions
extravasation will cause tissue necrosis
dopamine: side effects
increased myocardial oxygen demand, ischemia, tachydysrhythmias.
Naloxone Hydrochloride: Interactions
None
diazepam (Valium): mechanism of action
Enhances action of GABA, an inhibitory
neurotransmitter, which inhibits spread of electrical
activity from irritable focus during seizures, calms CNS.
Also a muscle relaxant.
Naloxone Hydrochloride: Indications
Symptomatic opiate overdose (respiratory depression), Clonidine overdose.
epinephrine: side effects
increased myocardial oxygen demand, ischemia, tachydysrhythmias, and anxiety.
Naloxone Hydrochloride: Dosage
0.1 - 2 mg(IV, IM, SQ, ETT, nasal), repeated to a max of 8 mg. Naloxone is shorter acting than most opiates, repeated doses may be required.
epinephrine: side effects
increased myocardial oxygen demand, ischemia, tachydysrhythmias, and anxiety.
Morphine Sulfate: Dosage
2-5 mg slow IV push, titrated to effect. Max dose usually not to exceed 20 mg without OLMC approval. MS can be given IM.
Morphine Sulfate: Precautions
Consider calling OLMC in the setting of multi-systems trauma. May cause N&V if given rapidly.
midazolam (Versed): side effects
Laryngospasm, bronchospasm, respiratory depression, drowsiness, amnesia, altered mental status
Naloxone Hydrochloride: Mechanism of action
Competitively displaces opioid analgesics from their receptor sites, reversing their effects. Respiratory depression, sedation, papillary miosis, and euphoric effects will be reversed.
epinephrine: dosage
Cardiac arrest: 1 mg/3-5 minutes IV (1:10,000)
Bradycardia: 2-10 mcg/minute
Anaphylaxis: 0.3–0.5 mg IM every 5–15 minutes (1:1000), 0.3-0.5 mg 3-5 minutes slow IV (1:10000).
Croup 0.5 mL via nebulizer (2.25% racemic epinephrine added to 3 mL saline)
Naloxone Hydrochloride: Class
Opiate antagonist
diazepam (Valium): precautions
Cannot be given IM. If possible use large vein and give slowly because of possible venous irritation. Monitor respiratory status
Morphine Sulfate: Mechanism of action
Combines with opioid receptors in the brain. Peripheral vasodialation of the veins and arteries resulting in decreased preload (not usually altering heart rate or blood pressure at usual doses).
Dopamine: indications
1 Significantly symptomatic hypotension (most commonly septic or cardiogenic shock). With the possible exception of cardiogenic shock, fluid resuscitation mast be attempted before the administration of dopamine.in the prehospital setting, dopamine is not used for shock in the setting of trauma.
epinephrine: indications
cardiac arrest: asystole and V-fib/tach without a pulse, PEA.also used in bradycardia (as a drip medicine only), anaphylaxis bronchospasm/constriction, and croup (racemic)
Diazapam (Valium): Contraindications
Hypotension, head injury and/or decreased mental status unless being given during RSI
lorazepam (Ativan): mechanism of action
Enhances action of GABA, and inhibitory neurotransmitter, inhibits spread of electrical activity from irritable focus during seizures, calmes CNS. Also a muscle relaxant.
Naloxone Hydrochloride: Side effects
Nausea, vomiting (if administered rapidly). Narcotic withdrawal symptoms: dizziness, hypertension, tachycardia, sweating, nervousness, abdominal cramps, headache, weakness, joint and muscle pain, insomnia, and untreated pain.
Diazapam (Valium): Indications
Major motor seizures, premedication for cardioversion ot TCP, sedation associated with intubation, muscle spasms, acute anxiety, agitation (amphetamine or cocaine OD)
Lorazepam (Ativan): Dosage
0.05mg/kg IV, max is generally 4mg
dopamine: mechanism of action
dopamine stimulates alpha and beta-1, and dopaminergic receptors. It also acts indirectly by causing release of norepinephrine from storage sites in the sympathetic nerve endings.the effects of dopamine are dose-related. At low doses, beta-1 and dopaminergic receptors are stimulated. At high doses out for the effects predominate.
diazepam (Valium):pharmacokinetics
Onset: 2-4 minutes
Duration: 30-90 minutes
epinephrine: mechanism of action
Epinephrine stimulates alpha and beta adrenergic receptors. Because of these effects the drug causes: peripheral vasoconstriction, increased inotropic, chronotropic, and dromatropic responses; and bronchodilation. Inhibits mast cell degranulation.
Dopamine: interactions
sodium bicarbonate can deactivate catecholamines. MAO inhibitors potentiate the effects of dopamine (Marplan, Eutonyl, Parnate, Nardil)
midazolam (Versed): mechanism of action
Enhances action of GABA, an inhibitory neurotransmitter; inhibits spread of electrical activity from irritable focus during seizures, calms CNS. Also a muscle relaxant.
Midazolam (Versed): Dosage
RSI: 0.1mg/kg IV, Max 10mg
Other sedation, seizure: 2.5mg-10mg IV/IM
Morphine Sulfate: Interactions
Potentiates other CNS depressants. Use caution with patients who have been drinking alcohol.
Dopamine: pharmacokinetics
IV drip administration has a rapid onset and will last as long as the drug is being infused.
Lorazepam (Ativan): Contraindications
Hypotension, head injury and/or decreased mental status unless being given during RSI
Midazolam (Versed): Indications
Major motor seizures, premedication for cardioversion ot TCP, sedation associated with intubation, muscle spasms, acute anxiety, agitation (amphetamine or cocaine OD)
epinephrine: contraindications
none when used in emergency situations, however in patients with a pulse, use caution if they have underlying cardiovascular disease, hypertension, or tachydysrhythmias.
dopamine: class
sympathomimetic, vasopressin
midazolam (Versed): class
benzodiazepine, anticonvulsant, sedative, hypnotic
diazepam (Valium): interactions
Effects are additive when used with other CNS depressants, for example, alcohol
dopamine: contraindications
pheochromocytoma, uncorrected tachydysrhythmia (except sinus tachycardia).
Naloxone Hydrochloride: Precautions
Can precipitate severe withdrawal symptoms in individuals physically dependent on opioids. Use repeated small doses (0.1-0.2 mg IV) in patients taking chronic narcotics. Consider physical restraints (and your personal safety) prior to, or concurrent with naloxone hydrochloride administration. may precipitate seizures in the neonate.
Morphine Sulfate: Side effects
Respiratory depression, hypotension, decreased mental status, histamine release.
Dopamine: how supplied
prefilled syringes and ampoules of either 400 or 800 mg. Premix bags with either 400 or 800 mg in 250 to 500 mL. Concentrations of mixtures vary, but most commonly are 1600 mcg/mL
midazolam (Versed): pharmacokinetics
Onset: 1-2 min IV; 15 min IM
Duration: 30-60 min IV, IM
Midazolam: Contraindications
Hypotension, head injury and/or decreased mental status unless being given during RSI.
Naloxone Hydrochloride: Notes
Larger doses may be required to reverse the effects of synthetic narcotics (propoxyphene, buprenorphine, butorphanol, nalbuphine, or pentazocine). Not useful in cardiac arrest even if cardiac arrest was a result of respiratory arrest caused by narcotic overdose. Naloxone will not restart an arrested heart.
