Introduction
Pediatric medicine, as well as pediatric pharmacy, acknowledges the specific healthcare needs of children by providing specialized sterile preparations that are safe and effective for this patient population

Pediatric CSPs
Pediatric CSPs are sterile solutions that typically have a volume of 500 mL or lessthe most commonly prepared pediatric CSPs include IV
push antibiotics, LVP solutions for hydration, and total parenteral nutrition solutions
the physical and chemical properties of parenteral pediatric medications vary somewhat, but most of these medications are generally isotonic, isoosmotic, and pH neutral

Pediatric Dosing
During child growth and development, the biochemical and physiological processes that control drug disposition undergo important changesthis is especially true for the first three years of a child’s
lifeat this young age, drugs may be absorbed or eliminated
more slowly or more rapidly than in adults

Pediatric Dosing…/2
Many factors must be considered when determining pediatric dosing for a patient, including:pediatric anatomy and physiologybody weight or body surface area
(BSA)agediagnosisdrug dispositionorgan functioning

Pediatric Formulations
Pediatric dosing has long been based on adult-strength formulations of medications
This method of dosing continues to be used today, with prescribers using body weight or BSA to help them determine appropriate dosages for parenteral medications

Pediatric Formulations…/2
2012 Paradigm Publishing
The high concentrations of adult-strength medications make reduction to child-sized doses difficult
Topics1111
Pediatric Formulations…/3
Many manufacturers have reformulated certain adult-strength medications into diluted concentrations, or pediatric-strength formulations, making pediatric dose preparation easier and more accurate
2012 Paradigm Publishing
Topics1212
Pediatric Formulations…/4
Regardless of whether the pediatric medication is based on an adult-strength formulation or a pediatric-strength formulation, all drugs for pediatric use are required to undergo studies prior to approval by the Food and Drug Administrationthis federal law—included in a 2007 amendment to the
Federal Food, Drug, and Cosmetic Act— was established to improve the safety and efficacy of pediatric medications
2012 Paradigm Publishing
Topics1313
Administration of Pediatric CSPs
Pediatric CSPs are primarily given as continuous IV infusions or as intermittent doses using the IV push route of administration
Continuous IV Infusion Many pediatric patients receive a continuous IV
infusion during their hospitalizationare generally comprised of an IV base solution to which an
additive, such as potassium chloride, is injected during sterile compounding procedures

the nursing staff to establish a central line or gain IV access through a femoral line or umbilical line

established, nursing personnel use an IV pump programmed to deliver the medication at a flow rate designated by the prescriber

Intermittent CSP Administration Parenteral medications
requiring intermittent dosing are commonly administered by the IV push route

Intermittent CSP Administration…continued Compounded Syringes
compounded syringes are syringes of medication that are compounded in the pharmacy and then sent to a nursing unit for patient administration
are typically sent without an attached needleusing a syringe cap rather than a capped needle is a
precautionary measure taken to avoid a needle stick from the accidental dislodgment of the needle cap during transport

Intermittent CSP Administration…continued Empty Evacuated Containers
often, a pediatric IV push medication is compounded into patient-specific vials or empty plastic bags known as empty evacuated containers (EECs)
useful for neonatal patients whose size dictates further dilution of a pediatric-strength drug with preservative-free (PF) sterile water or NS

EECs have several advantages for nursing and pharmacy personnel:• EECs can still be used if the patient dosage changes• EECs are transported as vials, not as syringes• preparing batches of EECs is easier and more
convenient one disadvantage of EECs is that they are more costly than
the syringe dosage form

continueda buretrol is a special type of tubing that contains a large,
tube-shaped cylinderthe IV push medication is injected into the cylinder, where
it mixes with a specific volume of fluid from the patient’s primary IV solution
the diluted medication is then administered through the tubing via a pump programmed to slowly inject the medication over a preset period

Potential Complications of Pediatric CSPs
All patients receiving parenteral therapy should be monitored for the following complications:nosocomial infectionallergic reaction (including anaphylaxis)phlebitistissuingembolismextravasationcellulitisStevens-Johnson syndromenephrotoxicity

Potential Complications of Pediatric CSPs…/2
Preparation Risks During the compounding of pediatric preparations,
pediatric CSP ingredients must be consideredbenzyl alcohol may cause damage to multiple organ
systems, potentially triggering a life-threatening condition called benzyl alcohol gasping syndrome
for this reason, only preservative- free (PF) ingredients should be used in pediatric CSPs
2012 Paradigm Publishing
Topics2626
Potential Complications of Pediatric CSPs…/3
Preparation Risks…continued The compounding of pediatric CSPs requires
additional oversight to ensure the accuracy of pharmacy calculationsbecause of the small size and delicate nature of pediatric
patients, even minor errors in dosage calculation of a pediatric CSP could be fatal
2012 Paradigm Publishing
Topics2727
Potential Complications of Pediatric CSPs…/4
Administration Risks Because children, especially
neonates, are so small, the total volume of parenteral fluid being administered to this patient population must be significantly smaller than the fluid volumes given to adult patients
2012 Paradigm Publishing
Topics2828
Potential Complications of Pediatric CSPs…/5
Administration Risks…continued If too much fluid were to be administered to a
neonate too quickly (generally referred to as accidental rapid administration), hypervolemia, cardiac arrest, or death may resultthe cause of such an error is most commonly a nursing or
IV pump error
2012 Paradigm Publishing
Topics2929
Potential Complications of Pediatric CSPs…/6
Administration Risks…continued Many hospitals avoid
accidental fluid overload by enacting policies that prohibit the use of 1000-mL IV bags with pediatric patientsin addition, facilities limit the
size of an IV bag to 250 or 500 mL for neonates

USP Chapter <797> Guidelinesfor Pediatric CSPs
IV technicians must adhere to strict dosage verification and aseptic protocols when preparing pediatric CSPsany breach in these protocols may result in medication
errors, sepsis, or, possibly, death for patient recipientsas an IV technician, you bear primary responsibility for the
preparation and integrity of the CSPs

Essential Supplies Most sterile compounding procedures require the
same essential supply items to be available for use in both the anteroom and the clean room

Procedure-Specific Supplies The type, number, and
amount of procedure-specific supply items are determined by the IV technician prior to performing the procedure, based on information provided on the CSP label and the medication additive label

Critical Sites of Essential Supplies and Pediatric CSP Supplies Before beginning preparatory procedures in the
anteroom or clean room, the IV technician must recall the critical sites of the suppliesidentifying the critical site of each supply item helps you
determine the proper procedure for handling the supply item once you have entered the clean room and begin working in the hood
