indicates that early and repeatedexposure to pain leads to adverseneurological outcomes, yet babies inneonatal intensive care have a meanof 16 painful procedures a day, themajority of which are performedwith inadequate analgesia and com-fort measures.2-4

Infants, including preterm babies,for whom intravenous opioid anal-gesics are not indicated, usually aregiven no pain reliever or comfortmeasure for routine minor painfulprocedures.5 Examples of thesepatients include a neonate whosecritical condition is improving aftersurgery, a baby who is being evalu-ated for sepsis in the emergencydepartment, and an infant withnonaccidental trauma who is beingtransferred from the pediatric inten-sive care unit to an acute care unit.

Newborn infants whoare sick experiencemultiple invasive andtissue-damaging pro-cedures in emergency,

acute, and critical care units. Theseprocedures (eg, lancing the heel,suctioning an endotracheal tube)are presumed to be painful andoccur during the early days of lifeas part of stabilizing, diagnosing,and treating a baby’s condition.Although neonates are capable ofmounting powerful physiological,behavioral, hormonal, and meta-bolic responses to nociceptive stim-uli, these responses can be harmfulto an infant’s behavioral and neuro-logical development.1,2 Evidence

radicals.9-20 The destructive interplayof pain, hypoxia, and toxic effectscaused by free radicals leads to pooroutcomes. Table 1 lists conditionsof newborns that are associatedwith these effects.9-20 Nurses mustconsider the long-term deleteriouseffects of repeated unmanaged painfor patients in the NICU, includingpreterm babies.9 Table 2 lists severalroutine invasive and painful proce-dures infants must undergo duringhospitalization. Of these, the heellance is the most common painfulprocedure in NICUs.21

Standard of CareA report22 published in 2000

revealed that only 5% of neonatalunits routinely used analgesia forcommonly performed painful pro-cedures such as venipuncture and

insertion of central catheters. Eightyears later, Bellieni and Buonocore23

reported a 30% increase in painmanagement for similar procedures.This increase is an improvement,albeit an unsatisfactory one, in painmanagement. Full attention tobabies’ personhood, promotion of

infants’ well-being ratherthan solely sur-vival, andincreased moralurgency in pro-viding analgesiahave beendescribed asethical changesthat may resultin effective paincontrol forinfants andbabies.23,24

Oral sucroseis a valuableanalgesic optionfor neonatesundergoingbrief proceduralpain.25 It has arapid onset ofeffects andshort-livedaction, thoughtto be mediatedby the release ofendogenous

brain opioids. Use of the sugar is lowrisk and it is simple to administer.Moreover, this intervention requiresminimal time from busy nurses.

Description and Forms ofOral SucroseSucrose is a disaccharide com-

posed of a-glucose and fructose ina 1:1 ratio.26 It is obtained commer-cially from sugarcane, sugar beets(Beta vulgaris), and other plants.27

Commonly known as table sugar,sucrose is a fine, white, crystallizedodorless substance used extensivelyas a food and sweetener. Table 3 listsdescriptions of oral sucrose in theliterature. The terms are relatively

synonymous for the same solutionand intent for use. The last 2 descrip-tions convey NNS more clearlybecause of the reference to a pacifier.When nurses evaluate the evidence,they should not discount studiesthat describe oral glucose as anintervention, because glucose is acomponent of sucrose. Oral sucrose is a solution of water

and sucrose. Two commercial oral

sucrose preparations are producedin the United States28,29 (Table 4).Ninety-one percent of the centersthat participated in a neonatalintensive care quality improvementcollaborative of 12 NICUs choseSweet-Ease (a prepackaged 11-mLcontainer).30 For the purpose of ourarticle, sucrose for infant analgesiais referred to as oral sucrose.

Research on Oral SucroseThe analgesic effects of sucrose

are not entirely understood. Themechanism of action is thought toinvolve activation of the endoge-nous opioid system (the release ofb-endorphins) through gustatorypathways or taste.31,32 A preabsorp-tive mechanism for sucrose-inducedanalgesia is supported by data on itspain-relieving effects after directapplication to the tongue but notafter administration into the

stomach via a nasogastric tube.31,33

Opioid receptors are present on thetongue, and studies in animals haverevealed analgesia reversal by opi-oid antagonists during noxiousstimulation.32 Conversely, findingsfrom 3 recent studies31,34,35 tend torefute the possibility of an endoge-nous opioid–mediated mechanismof effect of oral sucrose or a sweetsolution. Taddio et al31 found nosignificant difference in the serumconcentrations of b-endorphinsamong preterm infants before andafter a single dose of sucrose.Specifically, the authors31 found nodetectable increase in the serumlevels of the endorphins at the timethe analgesic effects of sucrose wereanticipated. Opioid tolerance wasnot observed in a study in whichinfants received repeated doses ofglucose.34 Finally, Gradin andSchollin35 found that intravenous

injection of an opioid antagonistdid not diminish the analgesic effectsof orally administered glucose givenbefore blood-sample proceduresamong newborn infants. Table 5summarizes the infant pain assess-ment scales that have been used inthe research on oral sucrose.The appropriate group of patients

for sucrose analgesia continues tobe defined. Evidence36 supports theefficacy of sucrose, with or withoutNNS, as a nonpharmacological pain-relieving intervention for minor pro-cedural pain in healthy full-terminfants. Although NNS reduces painbehaviors and heart rate in responseto heel lance, the addition of oralsucrose may result in a superioranalgesic effect.36 Weaknesses in themethods used in some studies con-tribute to the obscurity of the distinctbenefits of oral sucrose in pretermor sick infants.36 Sucrose has anal-gesic effects in infants as young as25 weeks’ gestation, and most of themedical centers in a neonatal paincollaborative study used sucrose invery low-birth-weight infants.33,37-39

Despite the demonstration ofthe effectiveness of oral sucrose invery low-birth-weight infants, someresearchers38,39 suggest that limiting

the administra-tion of oralsucrose toinfants morethan 32 weeks’gestational agemay be judi-cious becauseof possibleadverse effects.Johnston40

described pos-sible long-termadverse effects

associated with the administrationof a 24% solution of oral sucrose toinfants less than 31 weeks’ postcon-ceptional age. Infants who receivedhigh numbers of doses scored lowerthan infants who received fewerdoses on components of the Neu-robehavioral Assessment of thePreterm Infant. In addition, babieswho received more doses of oralsucrose had higher NeurobiologicRisk Scores at 2 weeks’ postnatalage, but they did not have higherscores at discharge. During 54 glucose interventions

(0.3 mL of a 30% oral glucose solu-tion) that were administered toneonates during subcutaneous injec-tions, 7 of the babies experiencedslight (85%-88%) and transient oxy-gen desaturations.41 Five neonatesexperienced oxygen desaturationsduring the administration of glucoseonly, whereas 2 experienced oxygendesaturations during the administra-tion of glucose and a pacifier.41 Thesefindings contrast the absence of oxy-gen desaturations associated with24 administrations of placebo.41

Infants (27-31 weeks’ gestationalage) who received a 24% solution oforal sucrose alone experiencedchoking, coughing, vomiting, or

sustained tachycardia or bradycar-dia.42 None of these adverse eventswere considered clinically important,and none of the babies who receivedoral sucrose and NNS experiencedadverse events.42 McCullough et al25

described adverse events associatedwith administration of oral sucroseto preterm infants in stable condi-tion who had insertion of a nasogas-tric tube. Brief apnea or self-limitingbradycardia occurred in a few infantsas a result of the sucrose adminis-tered or insertion of the tube. Noneof these events were clinically impor-tant or required intervention.Necrotizing enterocolitis and hyper-glycemia have been suspected adverseeffects, the latter more theoreticalthan well documented.38 Oral sucrosehas not been proved to cause eitherof these effects.38

The safety of oral sucrose forvery preterm infants has been afocus of investigation, and the effi-cacy of the sugar in older infantshas been questioned. Scrutiny ofthe literature on pain associatedwith immunization and use of oralsucrose at 2, 4, and 6 months of agehas led experts to conclude that theanalgesic effect of oral sucrose isdiminished at 4 months.30,38,39,43

The appropriate volume of oralsucrose has also been examined,and precise dosing based on age isnot clearly defined. Two independ-ent measurements indicated that thevolume of a 24% solution of sucroseadministered from a pacifier dippedonce was no greater than 0.2 mL.38

Sucrose volumes ranging from 0.5to 2 mL have been effective for anal-gesia for neonates.30,38,39,43,44 Interest-ingly, the analgesic effect is notdetermined by the volume butrather by the infant’s detection of a

sweet taste.38 Investigators38,44 havereported that 0.05 to 0.5 mL of a 24%to 25% solution of sucrose or glucoseis sufficient to provide analgesia.The onset of action of oral

sucrose is 10 seconds, peak actionoccurs at 2 minutes, and the effectpersists approximately 5 to 10 min-utes.37 Because of the rapid onset ofaction, analgesia is not attributableto oral absorption and clearancefrom the circulation. Research on use of oral sucrose

has evolved to include the investiga-tion of more and varied populationsof patients and painful procedures.For example, sucrose moderatelyreduced pain in newborns of bothdiabetic and nondiabetic motherswhen it was used for all medicalprocedures performed in the first 2days after birth.45 However, wheneach procedure was analyzed sepa-rately, sucrose reduced pain forvenipuncture but not for intramus-cular injection of vitamin K or heellance. Findings on the effectivenessof oral sucrose in reducing painand/or distress associated withscreening for retinopathy of prema-turity have been mixed.46,47

Studies other than those con-ducted in a NICU or a newborn nurs-ery have had varied findings on theuse of oral sucrose for non–skin-breaking procedures. For example,oral sucrose had no overall treatmenteffect in infants who were youngerthan 90 days and received the sugarfor bladder catheterization in theemergency department.48 Anotherexample is use of oral sucrose forinsertion of nasogastric tubes.McCullough et al25 reported thatinsertion in neonates evokes a painresponse comparable to that associ-ated with heel lance. In a randomized,

double-blind, placebo-controlledclinical trial,25 a 24% solution of oralsucrose was effective in reducingthe behavioral and physiologicalpain responses to insertion of anasogastric tube in preterm infants.Adverse effects (ie, brief apnea, self-limiting bradycardia) were few andoccurred equally in each group ofpatients, leading to the conclusionthat oral sucrose for this procedureis a safe intervention. Last, analgesia due to oral sucrose

administered for venipuncture maypersist through subsequent care suchas diaper changes.49 Table 6 lists vari-ations in research on oral sucroseanalgesia that make interpreting andimplementing the findings difficult.

dispensing system provides immedi-ate accessibility to clinicians and theretention of administration of oralsucrose as an independent nursingintervention guided by evidence-based pain policies and protocols.

Patient Safety and AdministrationAt one hospital, addition of oral

sucrose to preprinted admissionorders increased use of the sugarfrom 8% to 65% for obtaining bloodsamples at the time of admission.38

Oral sucrose may also be included inadmission order sets and pain man-agement screens or bands withinelectronic documentation systems.The data collection form of the

National Data Base for Nursing Qual-ity Indicators50 for pain assessment-intervention-reassessment cyclesdoes not include oral sucrose as aspecific analgesic intervention.However, the form does have thechoice for Other, and oral sucrosecan be included in this interventionoption. Nurses should have themeans to document oral sucrose asan intervention for pain managementwith reassessment of pain after theintervention. Nurses can documentoral sucrose as a component of apatient’s plan of care and pain edu-cation for an infant’s family. More-over, nurses may support parentsparticipating in this intervention.51

A patient care policy on use oforal sucrose should reflect consen-sus among the following disciplines:nursing, neonatology, general sur-gery, cardiothoracic surgery, painmedicine, critical care medicine, andpharmacy. A policy must specify whocan administer oral sucrose to new-borns when minor invasive proce-dures are performed (eg, radiological

technologists, phlebotomists). Insti-tution-specific factors (eg, productavailability) and parental prefer-ences are important considerationsin evidence-based practice. Table 7is an outline of the components of apolicy on use of oral sucrose. Dunbar and colleagues30 described

the administration of oral sucrosein combination with a pacifierbecause of the added analgesic effectof NNS. The oral sucrose wasdropped precisely onto the tonguewith an oral syringe and then theinfant was given a pacifier, or thesugar was administered by dippingthe pacifier in the sucrose solution.42

Parental Participation inProcedures for Pain ManagementIn light of the number of inva-

sive procedures a hospitalized new-born experiences, not surprisinglyparents of babies in NICUs identi-fied medical procedures as the majorsource of pain.52 Parents desire infor-mation about and involvement withtheir infants’ pain and have described

specific ways in which staff in theNICU can help them and their babiescope with pain.53 Parents who areempowered to administer oral sucroseto their newborn might be lessaffected by the infant’s pain and lessworried about their relationshipwith the infant as a result of painfulexperiences. Nurses are in an idealposition to assess parents’ prefer-ences for being involved in manag-ing infants’ pain and to facilitateparental independence in providingnonpharmacological pain interven-tions as part of patient-family–centered care.

Case ReportsThe following case reports are

about 2 patients treated in unitsother than an NICU or a newbornnursery. The standard of care forminor painful procedures relative toanalgesic medications for infants isrepresented. Age determinants foranalgesic effectiveness are consid-ered as well as the combination oforal sucrose with other nonpharma-cological pain interventions. Incom-plete details on pain control beforethe time covered in these case reportschallenge nurses to consider possibleimplications for the effectiveness orineffectiveness of oral sucrose.

Case Report 1: Oral SucroseEffectiveA newborn boy with coarctation

of the aorta was hospitalized in acardiac intensive care unit. He wasswaddled in a radiant warmer bed.

His parents were consulting with aphysician outside the unit. No anal-gesics had been ordered as part ofthe baby’s treatment plan. Theinfant required percutaneous intra-venous cannulation before surgicalcorrection of the cardiac abnormal-ity. A pacifier dipped in a 24% solu-tion of oral sucrose was provided tothe infant by a nurse 2 minutesbefore the intravenous cannulation.The infant had mild extremity with-drawal in response to the firsttourniquet application; his CRIESscore was 1. The CRIES pain assess-ment scale is used to measure cry,requirement for increased oxygenadministration, increase in vital signs,expression, and sleeplessness.53,54

Scores can range from 0 (no pain) to10 (the worst possible pain). Whena site was chosen for the intravenouscannulation and the procedure wasstarted with a break in the skin, thebaby continued to suck on the oralsucrose pacifier. The pacifier wasredipped and offered to the baby 3times during the procedure and forapproximately 1 minute after thecatheter was secured. The baby sleptthrough most of the procedure. Dur-ing brief wakefulness, his CRIESscore never increased to greater than1. The baby was swaddled again,and he was resting peacefully whenthe parents returned to the bedside.

Case Report 2: Oral Sucrose Ineffective A 4-month-old girl was hospital-

ized in a pediatric intensive care unitwith severe bronchopulmonarydysplasia that necessitated high-frequency oscillatory ventilationand prone positioning. When thebaby’s condition improved, oxygenwas administered via nasal cannula.

She required percutaneous intra-venous cannulation for maintenanceintravenous fluid before transfer toan acute care unit the next morn-ing. The nurse caring for the babyplayed a television channel in theinfant’s room that shows continualimagery scenes accompanied bymusic (eg, waterfalls, green mead-ows). No analgesics were orderedas part of the baby’s treatmentplan. She was soothed only brieflywith oral sucrose for the first tourni-quet application to an extremity.As the procedure went on, with 3unsuccessful attempts at percuta-neous intravenous cannulation, oralsucrose had no effect on the infant’spain, as indicated by no reductionin a CRIES score of 8. Whether ornot adequate pain managementwas provided earlier during hospi-talization for multiple urgent andnecessary invasive procedures,potentially resulting in hyperalge-sia, was not clear. The ineffective-ness of oral sucrose might have beenattributable to the infant’s age.

ConclusionOral sucrose has a valuable role

in reducing procedural pain forinfants. Generally, the sugar is safeand effective for infants who experi-ence minor invasive procedures.Inconsistencies in studies of theanalgesic effects of oral sucrose dur-ing common minor invasive proce-dures may be responsible for thevaried findings. Furthermore, anoptimal dose has yet to be deter-mined. Nurses need to rememberthat oral sucrose reduces, but maynot eliminate, pain. Combining oralsucrose with other nonpharmaco-logical interventions may enhancepain relief. Oral sucrose should not

newborns remains an area of researchand a relevant topic of interest.Additional investigation is neededon repeated administration of oralsucrose, optimal dosing, and use inbabies who have extremely lowbirth weight, are in unstable condi-tion, or are being treated withmechanical ventilation.55 CCN
