IV Fluids: Basic factsIV Fluids: Basic facts
Used primarily for volume replacement and
medication delivery.
Primarily Crystalloids in the Pre-hospital
arena
Large volumes may be needed, especially in
septic shock
CrystaloidsCrystaloids
Normal Saline: Good for Fluid Boluses, compatible with
blood products, most drugs. 0.9% NaCl has an osmolarity
of 308 mOsm/liter, slightly greater than that of plasma
Lactated Ringers: Good for fluid boluses but is mildly
hypo-osmolar when compared to plasma, resulting in
approximately 114 ml of free water per liter of LR
D5W: Mainly for Hypoglycemia in the stable pt or for
infants.
Dextrose containing solutions should not be used for
boluses as they will likely cause Hyperglycemia
Hyperglycemia is associated with poor neurological
outcomes.
ColloidsColloids
Colloid refers to a liquid that exerts osmotic pressure
due to large MW (greater than 30,000) particles in
solution. A variety of colloid solutions are seen for in
hospital use:
Hydroxyethyl starch (Hespan): hetastarch can cause a
coagulopathy, through hemodilution of clotting factors,
inhibition of platelet function and reduction of the activity
of factor VIII
Pentastarch (Pentaspan):Pentastarch differs from
hetastarch in that it has a lower mean MW. Preliminary
studies also suggest that pentastarch may have fewer
adverse effects on coagulation than hetastarch.25. No clear
pediatric value yet.
ColloidsColloids
Dextran solutions (dextran 40 and dextran 70): Similar
osmotic pressure to plasma. Dextrans interfere with normal
coagulation partly by hemodilution of clotting factors and
partly by “coating” platelets and the vascular endothelium.
May promote renal failure.
5% Human serum albumin: Protein based solution,
falling out of favor in some circles secondary to reports of
increased mortality in the critically ill adult population,
and some debate still lays in its use outside of the neonatal
arena.
Medications: Basic FactsMedications: Basic Facts
Ultimate Goal is to get Drug to the central
circulation.
Severe shock may sometimes inhibit that
goal.
Intravascular is usually the route of choice.
“Common” routes include IV, IO, ET and
central lines.
IV access and Meds : Basic IV access and Meds : Basic
FactsFacts
In the critical pediatric Pt, Time to establish
access should be kept to a minimum.
A General rule is “3 sticks in 90 seconds”
Do not delay drugs to await IV access, give
ET if required.
If traditional access is unlikely, proceed to
alternative means (IO in the child under 6)
IV access and Meds: Basic IV access and Meds: Basic
factsfacts
Use of a Braslow tape , Pedi Wheel , or
other aid is highly recommended
The rule of 6: 6 mg x wt in kg; add to
Volutrol and dilute to 100 cc total, X cc/hr
equals X mcg/kg/min
Use 0.6 mg/kg for Epi
Intraosseous Lines (IO’s)Intraosseous Lines (IO’s)
Will be covered in the skill station
All resuscitation meds can be given IO.
Valium is preferred PR.
Low risk of perm. Complications if done
correctly.
Endotracheal (ET)Endotracheal (ET)
Lipid soluble drugs can be given.
2-2.5 times standard IV dose. (except for
Epi)
Should be diluted to a volume of 3-5 ml
Should be hyperventilated after
A use a 5 fr Cath to deliver the med
depending on size of ETT, then flush w/ 3-5
ml after.
EndotrachealEndotracheal
L- Lidocaine
E- EPI
A- Atropine
N- Narcan (No established data regarding
use in peds)
EpinephrineEpinephrine
Most common
Alpha and Beta Adrenergic effects
2 standard concentration 1:1K and 1:10K
Used in PALS in your “Collapse Rhythms”

IV dose and move up
(Page 6-6)
One single study of 20 children (very small)
recommended High doses of Epi 0.2mg/kg All of these
children experienced witnessed arrest with ALS w/in 7
minutes
AtropineAtropine
Parasympatholytic
May or may not be truly effective in small
children in arrest/Asystole
Good for vagus suppression during ETT attempts
0.02 mg/kg dose
Max 0.5 mg
Minimum dose (no matter weight) is 0.1 mg to
avoid refractory bradycardia
Remember that most bradycardia in children are
hypoxic related.
Sodium BicarbSodium Bicarb
Used to treat metabolic acidosis during
resuscitation.
Poor perfusion and ventilation are largest
contributors to acidosis
Used after adequate ventilation has been restored.
0.1 meq/kg IV/IO, repeated at 0.5 meq/kg every
10 minutes
Half strength is used for infants younger than 3
months
Calcium Calcium
Calcium is indicated in documented /suspected
Hypocalcaemia,, Hypermagnesemia, and Calcium
Channel Blocker overdose
Available in Calcium Chloride or Calcium
Gluconate. CaCl is generally considered more
reliable and predictable in its metabilization, thus
it is used more often in the critically ill.
If Calcium Gluconate is used , its dose and volume
should be approx. 3 times that of CaCl to produce
similar effects.
Calcium (Continued)Calcium (Continued)
CaCl dosing is based on adult data, and little
Pediatric data exist.
1
st
dose should be 20 mg/kg (0.2 ml/kg) given
slowly (no greater than 100 mg/min)
Repeated doses of CaCl are associated with
increased mortality, so repeat once in 10 minutes
only if lab findings indicate it is needed.
Do not mix with bicarb
Rapid administration may cause Asystole or
refractory bradycardia.
NarcanNarcan
Narcotic Antagonist.
Rapid onset (w/in 2 minutes) and about 30 to 45 minute
effective duration
Doses given are for total reversal.
May use smaller doses if desired based on situation
< 5 years: 0.1 mg/kg
>5 years of age: up to 2 mg (use adult dosing.)
Infusion: 0.004-0.16 mg/hour for total reversal
maintenance.
Should be used in caution in newborns from addicted
mothers as it may cause withdrawal SZ.
LidocaineLidocaine
Anti-arrhythmic
Indicated for VF/pulse less VT and post
defibrillation arrhythmic suppressant.
Used in Tachycardia algorithm for WIDE
complex Tachycardia
Dose : 1 mg/kg max 3 mg/kg
If successful,proceed to infusion
BretyliumBretylium
No data regarding use in pediatrics
May be given IF Defib and Lidocaine are
ineffective under old guidelines,
Dose is 5 mg/kg, repeated at 10 mg/kg
Has been removed from NEW 2000
“Asystole/Pulseless arrest”guidelines
Replaced with Mag in algorithm.
D50D50
Critical children (especially infants may rapidly
deplete their glycogen stores, especially during
Cardiopulmonary distress
Glucose is especially important to the neonatal
heart.
All peds in distress should have their BG checked.
Dose 1.0 GM/KG IV/IO, max concentration of
25% (D25) used . A 10 % concentration may be
advisable for neonate (D10) , or D50 diluted 4:1 to
make D12.5 .
AdenocardAdenocard
Adenocard is indicated in Pediatric SVT for
NARROW complex Tachycardia and wide
complex Tachycardia AFTER lidocaine is
ineffective.
Infants >220 b/minute
Children > 180 BPM
Dose 0.1 mg/kg repeated at 0.2mg/kg once.
Follow with Flush (5 ml in infant)
The two syringe technique is recommended.\
Max dose 12 mg regardless of weight.
Epinephrine InfusionEpinephrine Infusion
Indicated in refractory shock, with a stable
rhythm and adequate volume.
May also be indicated for severe
symptomatic bradycardia
May be initiated in the pulse less arrest
refractory to Bolus Epi use

available.
DopamineDopamine
Vasopressor of choice for pre hospital use
Dose Dependant (2-5 mcg/kg/min increases renal
blood flow
5-10 mcg/kg/min cause Beta adrenergic effects,
may be decreased in sick hearts due to
norepinephrine stores depleted.
10-20 mcg/kg/min both alpha and beta effects
Greater than 20 mcg/kg/min not routinely
recommended, mimics norepinephrine.
Used in shock with out hypo-volemia or after it
has been treated.
