
Note: Amiodarone is incompatible with normal
saline solution.

20. Preparation: * Loading dose – Mix calculated loading
dose of amiodarone (5 mg per kg) in
250 ml of

dextrose 5%. Infuse for 1 to 2 hours (125 to 250 ml per
hour).
* Maintenance dose – Mix calculated

maintenance dose of amiodarone

(10 to 15 mg per kg) in 500 ml of dextrose 5%. Infuse for
24
hours (20 ml per hour).

21. Adenosine
Adenosine is a very short acting agent used in the
treatment of supraventricular tachycardia.
It is best given in incremental doses according to
response (usually 6 mg initially and if no response,
give 12 mg and if necessary followed by 18 mg).
 Adenosine should be given as a rapid intravenous bolus
followed by a 20 ml 0.9% saline flush.
In asthmatic patient --->bronchospasm ….
Antagonised by using Theophyllin.

22. Procainamide
Antiarrhythmic Agent, Class Ia.
IV: Loading dose: 15 to 18 mg/kg administered as
slow infusion over 25 to 30 minutes

or 100 mg/dose at a rate not to exceed 50
mg/minute repeated every 5 minutes as needed to a
total dose of 1 g.

23. Procainamide
Maintenance dose: 1 to 4 mg/minute by continuous
infusion. Maintenance infusions should be reduced
by one-third in patients with moderate renal or
cardiac impairment and by two-thirds in patients with
severe renal or cardiac impairment.
Dose must be titrated to patient's response

24. MANNITOLMANNITOL
Osmotic diuretic – for cerebral
edema  may inc ICP
 initial dose – 0.5-1g/kg IV of 25%
solution
Note: highly irritating to the veins
 forms crystals

25. Mannitol
If crystals are present, redissolve by warming
solution. Use filter-type administration set for
infusion solutions containing mannitol ≥20%.

26. METHYLPREDNISOLONE
Indication: spinal cord injury/cerebral
edema
* Contraindications:
HIV infection
 pregnancy
Uncntrolled diabetes

28. Poisoning:
Ingested Poisons
May be corrosive (alkaline and acid
agents that cause tissue destruction)
Alkaline productsAlkaline products: Lye, drain and
toilet bowl cleaners, bleach, non-
phosphate detergents, button
batteries
Acid products:Acid products: toilet bowl and
metal cleaners, battery acid

30. Poisoning Management
Ingestion of corrosive poison
give water or milk - for dilution
not attempted if patient has acute airway obstruction,
or if with evidence of gastric or esophageal burn or
perforation.
Ipecac syrup - induce vomiting in the alert patient
Gastric lavage for the obtunded patient
aspirate is tested
Activated charcoal administration if poison can
be absorbed by it
Cathartic (clearance bowels)Cathartic (clearance bowels) - when appropriate

31. Ingested Poison Warnings!!!
Vomiting is NEVER induced after
ingestion of caustic substances or
petroleum distillates.

32. 1.NALOXONE – anti-dote for opiates
overdose

depression secondary to
benzodiazepines

organophosphate poisoning

33. DOPAMINE
DOBUTAMINE
NOREPINEPRHINE
EPINEPHRINE
ALBUTEROL

34. Epinephrine:
α-adrenergic effects can increase
coronary and

cerebral perfusion
pressure by vasoconstriction
β-adrenergic can increase myocardial
contractility
Given 1 mg per IV/IO every 3-5
minutes

35.  Sympathomimetic
For hypotension (shock)
It can increase heart rate when
atropine has not been effective
Dose: 1-20mcg/kg/min (in 250ml D5W)
Wean patient gradually – can result
to severe hypotension if abruptly
stopped

36.  Assess IV site q1 hr
Extravasation can lead to
tissue necrosis

37.  sympathomimetic with beta 1
effects (inc. heart rate)
 no vasoconstriction, only
increase cardiac output
 dose: 250-1000mg in 250ml
D5W or NSS

38.  AN EXTREMELY POTENT
VASOCONSTRICTOR
GIVEN WHEN DOPAMINE AND
DOBUTAMINE HAVE FAILED
DOSE: 4-8mg to 250ml D5W or
NSS and infused at 0.5-30mcg/min

39. ANAPHYLACTIC SHOCK

 Reverses bronchoconstriction
Beta
2
Agonist

swelling and pruritus
25-50mg IV or deep IM

41.
 DRUGS FOR
HYPERTENSIVE CRISIS

exceeds 110-120mmHg and
pulmonary edema

42.
 DRUGS FOR
HYPERTENSIVE CRISIS
LABETALOL
Beta blocker

contractility, and myocardial O2
consumption

(max dose: 150mg)
Contraindicated in patients with
Asthma

43.
 DRUGS FOR
HYPERTENSIVE CRISIS
SODIUM NITROPRUSSIDE
Reduces arterial BP
Effect: immediate vasodilation
and BP goes down but
immediately goes up once the
drug is stopped

44.
 DRUGS FOR
HYPERTENSIVE CRISIS
SODIUM NITROPRUSSIDE
 inactivated by light – wrap in
aluminum foil
Blue or brown discoloration –
means drug is degraded
 prolonged use – can lead to
cyanide poisoning

46.
 DRUGS FOR
HYPERTENSIVE CRISIS
FUROSEMIDE
 loop diuretic
 For acute pulmonary edema due
to left ventricular dysfunction or
hypertensive crisis
 diuresis may start within 20 mins

47.
 DRUGS FOR
HYPERTENSIVE CRISIS
FUROSEMIDE
Adverse effects: hypotension,
dehydration and electrolyte
imbalances
 can result to allergic reaction

48. Antiepileptic drugs
Phenytoin;
must be given by slow intravenous injection.
The infusion rate should not exceed 50 mg per minute
in adults or 1 mg per kg per minute in children.
Preparation:. should be diluted in 0.9% saline only
(not 5% dextrose) so that the concentration is no greater
than 5 mg per ml. Rapid infusion of concentrated
solutions may cause hypotension. The usual loading
dose is 15 mg per kg intravenously.
