`Intravenous Admixtures

`
`It has been estimated that 40% of all drugs administered in
`hospitals are given in the form of injections and their use is
`increasing. Part of this increase in parenteral therapy is due
`to the wider use of intravenous fluids (IV fluids). In the last
`decade the use of IV fluids has doubled, increasing from 150
`million units to 300 million units annually. Not only do IV
`fluids continue to serve as the means for fluid replacement,
`electrolyte-balance restoration and supplementary nutri(cid:173)
`tion, but they also are playing major roles as vehicles for
`administration of other drug substances and in total paren(cid:173)
`teral nutrition (TPN). TPN fluids are finding greater use as
`the means of administering other drugs because of conve(cid:173)
`nience, the means of reducing the irritation potential of the
`drugs and the desirability for continuous and intermittent
`drug therapy. The techniques for providing TPN parenter(cid:173)
`ally have improved steadily in the last decade, and such use
`is increasing markedly. The use of IV fluids for these pur(cid:173)
`poses requires the compounding of specific intravenous ad(cid:173)
`mixtures (parenteral prescriptions) to meet the clinical
`needs of a given patient. However, the combination of drug
`substances in an IV fluid can promote parenteral incompati(cid:173)
`bilities and give rise to conditions not favorable for drug
`stability. A new area of specialization has been created for
`hospital pharmacists who can develop the expertise to pre(cid:173)
`pare these solutions-recognizing their compatibility and
`stability problems and the potential for contamination(cid:173)
`and participate in the administration of the solutions. The
`complex compounding of an order for TPN requires know(cid:173)
`ledgeable personnel capable of making accurate calcula(cid:173)
`tions, compounding and having aseptic technique. The par(cid:173)
`enteral prescription is becoming increasingly important in
`hospitals. Centralized admixture programs are now found
`in 70% of the nation's hospitals having 300 beds or more.
`Equipment available for administering IV fluids has become
`more sophisticated, and has made possible increased accura(cid:173)
`cy of dosage and led to the development of new concepts and
`methods of nutrition and drug therapy.
`
`Intravenous Fluids
`
`Large-volume injections intended to be administered by
`intravenous infusion commonly are called IV fluids and are
`included in the group of sterile products referred to as large(cid:173)
`volume parenterals. These consist of single-dose injections
`having a volume of 100 mL or more and containing no added
`substances. Intravenous fluids are packaged in containers
`having a capacity of 100 to 1000 mL. Minitype infusion
`containers of 250-mL capacity are available with 50- and
`100-mL partial fills for solution of drugs when used in the
`"piggyback" technique (ie, the administration of a second
`solution through a Y-tube or gum-rubber connection in the
`administration set of the first intravenous fluid, thus avoid(cid:173)
`ing the need for another injection site). In addition to the
`IV fluids, this group also includes irrigation solutions and
`solutions for dialysis.
`Intravenous fluids are sterile solutions of simple chemi-
`
`cals such as sugars, amino acids or electrolytes-materials
`which easily can be carried by the circulatory system and
`assimilated. Prepared with Water for Injection USP, the
`solutions are pyrogen-free. Because of the large volumes
`administered intravenously, the absence of particulate mat(cid:173)
`ter assumes a significant role in view of possible biological
`hazards resulting from insoluble particles. Absence of par(cid:173)
`ticulate matter or clarity of IV fluids is as important at the
`time of administration following their manipulation in the
`hospital as it is at the time of manufacture of the injection.
`Limits for particulate matter occurring in IV fluids, or
`large-volume injections used for single-dose infusion, are
`defined in the USP. This represents the first regulatory
`attempt to define limits for particulate matter in paren(cid:173)
`terals. Limits also apply to multiple-dose injections, small(cid:173)
`volume injections or injections prepared by reconstitution
`from sterile solids. The USP defines particulate matter as
`extraneous, mobile, undissolved substances, other than gas
`bubbles, unintentionally present in parenteral solutions.
`The total numbers of particles having effective linear di(cid:173)
`mensions equal to or larger than 10 µm and larger than 25 µm
`are counted. The IV fluid meets the requirement of the test
`if it contains not more than 50 particles per mL which are
`equal to or larger than 10 µm, and not more than 5 particles
`per mL which are equal to or larger than 25 µm in linear
`dimension.
`Intravenous fluids commonly are used for a number of
`clinical conditions. These include
`Correction of disturbances in electrolyte balance.
`Correction of disturbances in body fluids (fluid replacement).
`The means of providing basic nutrition.
`The basis for the practice of providing TPN.
`Use as vehicles for other drug substances.
`
`In both of the latter two cases it has become common prac(cid:173)
`tice to add other drugs to certain IV fluids to meet the
`clinical needs of the patient. Using IV fluids as vehicles
`offers the advantages of convenience, the means of reducing
`the irritation potential of the drug and a method for continu(cid:173)
`ous drug therapy. However, the practice requires that care(cid:173)
`ful consideration be given to the stability and compatibility
`of additives present in the IV fluids serving as the vehicles.
`This approach also demands strict adherence to aseptic
`techniques in adding the drugs, as well as in the administra(cid:173)
`tion of the IV fluids. These procedures are discussed later
`in the chapter. The IV fluids commonly used for parenter(cid:173)
`als are shown in Table I.
`Many disease states result in electrolyte depletion and
`loss. Proper electrolyte concentration and balance in plas(cid:173)
`ma and tissues are critical for proper body function. Elec(cid:173)
`trolyte restoration and balance are achieved most rapidly
`through administration of IV fluids. Required electrolytes
`include sodium and chloride ions, which in normal saline
`more closely approximate the composition of the extracellu(cid:173)
`lar fluid than solutions of any other single salt; potassium,
`the principal intracellular cation of most body tissues and an
`essential for the functioning of the nervous and muscular

`systems as well as the heart; magnesium, as a nutritional
`supplement especially in TPN solutions and phosphate ion,
`important in a variety of biochemical reactions. In addition
`to the number of standard electrolyte fluids shown in Table
`I, a large number of combinations of electrolytes in varying
`concentrations are available commercially, Some of these
`electrolyte fluids also contain dextrose.
`Dextrose Injection 5% (D5/W) is the most frequently used
`IV fluid, either for nutrition or fluid replacement.
`It is
`isotonic and administered intravenously into a peripheral
`vein; l g of dextrose provides 3.4 cal and I L of D5/W
`supplies 170 cal. The body utilizes dextrose at a rate of 0.5 g
`per kg of body weight per hr. More rapid administration
`can result in glycosuria. Therefore, 1 L of D5/W requires
`1 ½ hours for assimilation. The pH range of D5/W can vary
`from 3.5 to 6,5. The wide range permitted is due to the free
`sugar acids present and formed during the sterilization and
`storage of the injection. To avoid incompatibilities when
`other drug substances are added to Dextrose Injection, the
`possible low pH should be considered in using it as a vehicle.
`
`More concentrated solutions of dextrose are available and
`provide increased calorie intake with less fluid volume. Be(cid:173)
`ing hypertonic, the more concentrated solutions may be irri(cid:173)
`tating to peripheral veins. Highly concentrated solutions
`are administered in a larger central vein. Other IV fluids
`used for intravenous admixtures and providing calories in(cid:173)
`clude solutions containing invert sugar. There is some evi(cid:173)
`dence that fructose, unlike dextrose, may be used in diabetic
`patients; the 10% injection is hypertonic and provides 375 cal
`per L. Invert sugar consists of equal parts of dextrose and
`fructose; it is claimed that the presence of fructose promotes
`more rapid utilization of dextrose.
`Intravenous fluids containing crystalline amino acids can
`provide biologically usable amino acids for protein synthesis
`(Chapter 51). Protein contributes to tissue growth, wound
`repair and resistance to infection. The protein requirement
`for the normal adult is 1 g per kg per day; children and
`patients under stress require greater amounts. Attempts
`are made to maintain a positive nitrogen balance, indicating
`that the protein administered is being utilized properly and

`not broken down and eliminated through the urine as creati(cid:173)
`nine and urea, which are normal waste products. In a posi(cid:173)
`tive nitrogen balance patients are taking in more nitrogen
`than they are eliminating. In a negative nitrogen balance
`there is more nitrogen being eliminated through the urine
`regularly than is being administered intravenously. This
`means that tissues are continuing to be torn down and repair
`is not necessarily taking place. Amino Acid Injection can
`afford the total body requirements for proteins by the proce(cid:173)
`dure known as TPN (discussed below) or be used for supple(cid:173)
`mental nutrition by peripheral administration. In addition
`to the amino acids, these nutritional injections also may
`contain dextrose, electrolytes, vitamins and insulin. Fat
`emulsion (Intralipid, Kabi Vitrum AB; Liposyn II, Abbott
`and Trauamulsion; Travenol) sometimes is used concur(cid:173)
`rently but usually administered at another site.
`
`Packaging Systems
`
`Containers for intravenous fluids must be designed to
`maintain solution sterility, clarity (freedom from particulate
`matter) and nonpyrogenicity from the time of preparation,
`through storage and during clinical administration. Con(cid:173)
`tainer closures must be designed to facilitate insertion of
`administration sets through which the injections are admin(cid:173)
`istered, at a regulated flow-rate, into suitable veins.
`IV
`fluids are available in glass and plastic containers; the latter
`may be made from either a flexible or semirigid plastic mate(cid:173)
`rial. IV fluids are supplied in 1000-mL, 500-mL and 250-
`mL sizes in addition to 250-mL capacity containers pack(cid:173)
`aged with 50 or 100 mL of D5/W or Sodium Chloride Injec(cid:173)
`tion for piggyback use.
`IV fluids in glass containers are
`packaged under vacuum, which must be dissipated prior to
`use. For fluid to leave the IV glass container and flow
`through the administration set, some mechanism is neces(cid:173)
`sary to permit air to enter the container. Current flexible
`plastic systems do not require air introduction in order to
`function. Atmospheric pressure pressing on the container
`forces the fluid to flow.
`All glass and plastic containers are single-dose and should
`be discarded after opening even if not used.
`Intravenous
`fluids are packaged with approximately 3% excess fill to
`allow for removal of air from the administration set and
`permit the labeled volume to be delivered from the contain(cid:173)
`er. The containers are graduated at 20-mL increments on
`scales that permit the volume in container to be determined
`either from an upright or inverted position. Glass contain(cid:173)
`ers have aluminum and plastic bands for hanging, while
`plastic containers have eyelet openings or plastic straps for
`attachment to IV poles.

`
`Administration Sets
`
`Administration sets used to deliver fluids intravenously
`are sterile, pyrogen-free and disposable. Although these
`sets are supplied by different manufacturers, each for its
`own system, they have certain basic components. These
`include a plastic spike to pierce the rubber closure or plastic
`seal on the IV container, a drip (sight) chamber to trap air
`and permit adjustment of flow rate and a length (150 to 450
`cm) of polyvinyl chloride tubing terminating in a gum-rub(cid:173)
`ber injection port. At the tip of the port is a rigid needle or
`catheter adapter. An adjustable clamp (screw or roller
`type) on the tubing pinches the tubing to regulate flow.
`Since the gum-rubber port is self-sealing, additional medica(cid:173)
`tion can be added to the IV system at these ports of entry.
`Glass containers that have no air tubes require air-inlet
`filters designed as part of the administration set (Abbott).
`See Figs 85-1 to 85-5.

`to 8-hr period. In some cases an IV fluid is infused slowly
`for the purpose of keeping the vein open (KVO). This will
`allow additional drugs to be administered when required.
`The primary IV fluid also can serve as a vehicle for other
`drugs to be administered, thus becoming an intravenous
`admixture (IV drip) and results in continuous blood levels of
`added drugs once the steady state has been reached.

`
`1. The spike adapter of the administration set is inserted into the
`stopper or seal of the IV container. See Fig. 85-5.
`2. The IV fluid is hung on a stand al bedside and air is purged from
`the administration set by opening the clamp until fluid comes out of
`needle. The tubing is then clamped off. See Fig 85-5.
`3. The venipuncture is made by member of the IV team, floor nurse
`or physician.
`4. The infusion rate is adjusted by slowly opening and closing the
`clamp until the desired drop rate, viewed in the drip chamber, is ob(cid:173)
`tained. The usual running time is4 to 8 hr (usually 125 mL are delivered
`in 1 hr). Drugs such as heparin, insulin, lidocaine or dopamine may be
`present in the IV drip. When potent drugs are present, the flow rates
`will vary depend on the clinical condition of the patient. Sets are
`calculated to deliver 10, 15, 20, 50 or GO drops per mL depending on the
`manufacturer. See Fig 85-5.
`Intermittent administration of an antibiotic and other
`drugs can be achieved by any of three methods: (1) direct
`intravenous injection (IV bolus or push), (2) addition of the
`drug to a predetermined volume of fluid in a volume-control
`device or (3) use of a second container (minibottle, minibag)
`with an already hanging IV fluid (piggybacking).
`Direct Intravenous Injection-Small volumes (1 to 50
`mL) of drugs are injected into the vein over a short period of
`time (1 to 5 min). The injection also can be made through a
`resealable gum-rubber injection site of an already hanging
`IV fluid. This method is suitable for a limited number of
`drugs but too hazardous for most drugs.
`Volume-Control Method-Volume-control sets provide
`a means for intermittent infusion of drug solutions in precise
`quantities, at controlled rates of flow. These units consist of
`calibrated, plastic, fluid chambers placed in a direct line
`under an established primary IV container or more often
`attached to an independent fluid supply. In either case, the
`drug to be administered is first reconstituted if it is a sterile
`solid and injected into the gum-rubber injection port of the
`volume-control unit. It is then further diluted to 50 to 150
`mL with the primary fluid or the separate fluid reservoir.
`Administration of the total drug-containing solution re(cid:173)
`quires 30 to 60 min and produces a peak concentration in the
`blood followed by a valley if the dosage is discontinued. The
`following volume-control sets are available commercially:
`Soluset, Abbott; Buretrol, Baxter and Metriset, McGaw.
`The procedure for setting up an intermittent IV infusion
`with a volume-control set is as follows:
`
`I. Using aseptic technique, the spike of the volume-control set is
`inserted into the primary IV fluid or a separate t1uid container. See Fig
`85-6.
`2. Air is purged from tubing of the volume-control set by opening the
`clamps until fluid comes through.
`3. The clamp is opened above the calibrated chamber and it is filled
`with 25 to 50 mL fluid from the primary IV container or separate fluid
`container.
`4. The clamp is closed above the chamber.
`5. The medication is injected through the gum-rubber port of the
`volume-control unit.
`6. The clamp above the chamber is opened to complete the dilution
`to the desired volume (50 to 150 mL), then closed.
`7. Flow commences when the clamp below the volume-control unit is
`opened.
`Piggyback Method-The piggyback method (Figs 85-7
`and 85-8) refers to the intermittent IV drip of a second
`solution, the reconstituted drug, through the venipuncture
`site of an ~stablished primary IV system. With this setup

`
`the drug can be thought of as entering the vein on "top" of
`the primary IV fluid, hence the designation "piggyback."
`The piggyback technique not only eliminates the need for
`another venipuncture, but also achieves drug dilution and
`peak blood levels within a relatively short time span, usually
`30 to 60 min. Drug dilution helps to reduce irritation, and
`early high serum levels are an important consideration in
`serious infection requiring aggressive drug therapy. These
`advantages have popularized the piggyback method of IV
`therapy, especially for the intermittent administration of
`antibiotics. In using the piggyback technique, the secon(cid:173)
`dary unit is purged of air and its needle inserted into a Y(cid:173)
`injection site of the primary set or into the injection site at
`the end of the primary set. The piggyback infusion is then
`started. Once it is completed, the primary fluid infusion
`will be restarted. See Fig 85-8.
`Primary IV administration sets are available that have a
`built-in check valve for use in piggyback administration.
`When the piggyback is connected to one of these sets and
`started, the check valve automatically closes off the primary
`infusion. When the piggyback runs out, the check valve
`automatically opens, thereby restarting the primary infu(cid:173)
`sion. The check valve works because of pressure differ(cid:173)
`ences. To achieve this difference, the primary container is
`hung lower than the secondary bottle by means of an exten(cid:173)
`sion hanger. See Fig 85-9.
`Manufacturers have introduced minibottles prefilled with
`various antibiotic products; each container is provided with
`a plastic hanger for direct suspension from an IV pole as the
`piggyback solution is adm
