According to the Healthcare Cost and Utilization Project, more than 5,000,000 children in the United States had a hospital stay in 2017. Many of them experienced some type of pain. Pain has an immense impact on the mind and body. In addition to the physical sensation of pain, effects include emotional suffering, pulmonary complications, decreased mobility, poor sleep, immune impairment, reduced quality of life, economic costs, and a potential for developing persistent (chronic) pain syndromes. Despite advances in care, many children continue to experience significant pain because of undertreatment and inadequate pain management after surgery. Sparing children the short- and long-term effects of pain requires early recognition and treatment.

Nurses are critical to pain prevention, recognition, and treatment in children. They’re with patients more than any other healthcare professionals and have the opportunity to assess pain throughout their shift. When pain is diagnosed, the nurse can start planning which interventions are most appropriate for individual patients. After interventions are implemented, the nurse should reassess the patient’s pain and response to treatment to evaluate intervention effectiveness.

Nurses have identified barriers (many outside of their control) to pediatric pain management. Czarnecki and colleagues’ 2019 multisite study of barriers to pediatric pain management found commonalities across the United States. The most frequently identified barriers included inadequate provider orders, insufficient time to provide pain medication before a procedure, insufficient premedication orders before procedures, and low priority given to pain management by medical staff. Regardless of role or setting, nurses can be empowered to overcome these barriers and provide optimal pain management. For example, they can use the electronic health record to develop order sets that include analgesic options, reducing barriers to adequate and timely orders. At a system level, nurses can collaborate with interprofessional teams on quality improvement projects to remove barriers that are out of the nurse’s control but within the area of other professionals’ work. In the Czarnecki study, concerns about addiction, limitations in nurses’ ability to assess pain, and a low priority given to pain by nursing staff were rated among the least frequently identified barriers.

Assessment

Historically, pain intensity numbers were viewed as key to patient assessment, and pain was considered the 5th vital sign. Although this was interpreted as requiring a pain score along with other vital signs, a true pain assessment should capture more than just a number. It should describe the patient’s pain experience, including its nature, impact, and context. Parental input can help differentiate pain from anxiety or other sources of distress in pediatric patients.

Pain intensity ratings are one piece of a pain assessment, but function is more important. Among adult patients, pain intensity ratings are being replaced with multidimensional pain assessments. For example, the Clinically Aligned Pain Assessment Tool guides the conversation between nurse and patient, focusing on general comfort, treatment effectiveness, whether pain is getting better or worse, activity level, and sleep quality. The tool can be adapted for use with children. Not all categories may apply to all pediatric patients, so the tool should be individualized and include parental input.

When used, pain intensity ratings should be gathered with developmentally appropriate, reliable, and validated tools. (See Choosing the right pain scale.)

Choosing the right pain scale

Pain scales have been developed for various pediatric populations. Nurses should select scales that are valid, reliable, user friendly, and easy to incorporate into practice. No matter which scale is used, re-assessment after interventions is a necessary component of the pain management plan.

Neonates and infants

Premature infants, starting around 20 weeks gestation, can perceive and respond to pain. To conserve energy, they frequently show a less-robust physical response compared to full-term infants (for example, they are more likely to close their eyes instead of grimacing and often have lower oxygen saturation levels). This unique response requires a scale specific to premature infants.

  • The Premature Infant Pain Profile (PIPP), although less commonly used now because it’s valid only in premature infants ≤ 37 weeks gestation, is well equipped to measure pain in this patient population. The Neonatal Pain, Agitation and Sedation Scale (N-PASS) includes a sedation assessment so that only one scale is needed for infants 23 weeks gestation through 100 days of life. The N-PASS scores pain/agitation from 0 to 10 and sedation from -10 to 0.
  • Scales appropriate for full-term and older infants include the Neonatal Infant Pain Scale, the FLACC (Face, Legs, Activity, Cry, Consolability) scale, Child Facial Coding System, CRIES (Crying, Requires increased oxygen administration, Increased vital signs, Expression, Sleeplessness) score, Children’s Hospital of Eastern Ontario Pain Scale, Riley Infant Pain Scale, and Children and Infants Postoperative Pain Scale.

Toddlers

When possible, self-report scales are preferred over behavioral or observational scales in this patient population. When children communicate pain with words (usually by age 3 to 4 years), many can self-report using faces scales.

  • Several self-report faces scales exist, each with varying levels of validity and reliability. These scales require the child to point to the face that best depicts their pain level. Examples include Faces Pain Scale-Revised (FPS-R) and Wong-Baker FACES pain rating scale. Nurses should use the same scale with a child rather than alternating between scales. The FPS-R has been used with smartphone technology with some success.

School age and adolescents

Many older children (8 years and older) can self-report pain by using a 0 to 10 scale.

  • Numeric rating scales are easy to use and may be verbal (Verbal Numerical Rating Scale) or written (Visual Analogue Scale).

Children with cognitive developmental delays

These children are at increased risk for poor pain assessment and management. Although their pain response may be diminished, no studies have demonstrated a decrease in pain sensation. Voepel-Lewis found that when self-report isn’t possible, facial cues are highly sensitive indicators of postprocedure and postoperative pain. Several scales exist, each with varying levels of reliability and validity.

  • The revised FLACC (r-FLACC) has been validated in children from age 4 to 19 years. Using the original FLACC scale as a base, additional indicators (such as head banging and breath holding) were added, along with space for parents to document any features unique to their child.
  • Another helpful tool is the Individualized Numeric Rating Scale. Caregivers are asked to assign a number to typical pain behavior seen in their child. The scale must be periodically updated because pain signs may change as the child ages.

Intubated and mechanically ventilated children

Very few validated scales exist for this patient population.

  • The COMFORT scale, which Van Dijk and colleagues demonstrated to be reliable and valid, is one of the more commonly used scales in this population. It uses six behavioral and two physiological metrics for a total score from 8 to 40.
  • An American Society of Pain Management Nursing position statement recommends using self-report if possible, evaluating potential sources of pain, assessing patient behaviors, incorporating physiologic measures (keeping in mind that they may not be specific to pain), soliciting input from parents, and assuming pain is present if the child is undergoing a painful procedure or has known reasons for pain.

Treating pain in children and adolescents

Pain management should take an individualized, multimodal (nonpharmacologic and pharmacologic), and interprofessional approach. The Pain Management Best Practices Inter-Agency Task Force identified gaps where multimodal, nonopioid treatment options were underused, especially in acute care settings. This report suggests the need for more guidelines, including a multimodal approach.

Nonpharmacologic approaches

Nonpharmacologic approaches to pain treatment should be tailored to the developmental level of the child and their individual needs. Treatment plans should be developed to effectively manage the child’s pain with an overarching goal of improving function. Involving the patient and family in treatment planning is essential for developing realistic expectations and goals.

The Joint Commission standards encourage hospitals to provide nonpharmacologic pain treatment and monitor intervention outcomes. Frequently, acute pain, especially in the hospital, is treated with a combination of nonpharmacologic and pharmacologic options. In contrast, when working with children and adolescents with persistent pain, nonpharmacologic treatment options frequently are the mainstay of pain treatment.

Nonpharmacologic pain interventions can be categorized as behavioral, cognitive, restorative, and complementary. A child life therapist can work with a child before a procedure or surgery to help facilitate therapeutic play and teach behavioral and cognitive techniques they can use throughout their lives to manage pain or uncomfortable situations. These techniques include deep breathing, self-coping skills, guided imagery, and virtual reality. In addition, music and reduced stimulation can create a soothing environment. (See Age-appropriate options.)

Age-appropriate options

Pediatric-pain-management-Age-appropriate-options

Nonpharmacologic pain management interventions should be age-appropriate.

Infants

  • Breastfeeding
  • Oral sucrose
  • Non-nutritive sucking
  • Swaying (rocking the infant back and forth)
  • Swaddling

Toddlers

  • Bubbles, toys, books, or other objects for distraction
  • Comfort holds (secure hugging by a parent or caregiver that helps the child feel safe and secure, decreases movement, and allows the parent to appropriately participate in the procedure)

School-age children

  • Comfort holds during procedures
  • Video games, toys, books, bubbles, and other objects for distraction

Adolescents

  • Whenever possible, allow adolescents to use their independence, make choices, and apply coping skills they’ve previously acquired.
  • Adolescents may want more privacy or social support from peers and others, compared to other age groups.
  • They may prefer technology (phone or laptop) for distraction.

Restorative therapies, such as physical therapy, occupational therapy, and therapeutic recreation, can help restore a child to optimal function when they’re experiencing acute pain. These therapies are essential for children with persistent pain.

According to Brittner and colleagues, complementary and integrative health modalities, such as massage and acupuncture, are showing some promising effects when used as part of a multimodal approach to treat various types of pain in children. Their evidence supports the safe use of acupuncture in children, and findings suggest this type of integrative approach can be beneficial for improving infant colic, headaches, dysmenorrhea, and other types of pain.

For children of all ages, parental involvement to provide comfort and reassurance is beneficial to both the parent and the child. However, nurses must recognize when parent or caregiver stress and anxiety may be upsetting the child. When that’s the case, nurses can help by providing open channels of communication, sharing information, and involving the parent in their child’s care (bathing, comfort holds, distraction) when possible.

Pharmacologic approaches

A variety of medication classes can be used to treat pain in children. The medication selection should consider the nature (for example, physical or emotional, acute or persistent) and intensity of the pain, its characteristics (for example, sharp, dull), and duration.

Nonopioid analgesics. Nonopioid medications, such as acetaminophen (I.V., oral, or rectal) and nonsteroidal anti-inflammatory drugs (NSAIDs) can be used to treat most types of pain. NSAIDs are recommended for mild to moderate pain and as part of a multimodal treatment plan for severe pain when using stronger analgesics such as opioids. Even in the postoperative setting, scheduled acetaminophen and NSAIDs may provide enough analgesia for children to tolerate pain. When any medication (including over-the-counter [OTC] drugs) is administered to a child, doses must be determined based on weight and age. Some OTCs may be contraindicated for children with certain clinical issues, such as liver or kidney disease and bleeding disorders. Nurses should screen for contraindications and teach parents and caregivers how to use nonopioid analgesics appropriately to help manage their child’s pain.

Adjuvant medications (such as tricyclic antidepressants) or anticonvulsants (such as gabapentin) can be used for persistent neuropathic pain. A study by Baxter and colleagues indicates that these medications can help reduce opioid use to treat postoperative pain in pediatric patients. Some pediatric organizations use low-dose ketamine or lidocaine infusions to help manage acute and neuropathic pain. Benzodiazepines can be used in the acute setting to treat muscle spasms; however, these medications can cause sedation and should be used with extreme caution when given in conjunction with opioids or other sedating medications. Medications such as baclofen or tizanidine, which cause less sedation, may be more appropriate for pediatric patients.

Opioid analgesics. Opioids are reserved for managing severe pain. When prescribed for children, opioids are given orally or intravenously. The oral route is easy and inexpensive, and most short-acting opioids are available in a liquid or tablet form. Some oral opioids, such as hydrocodone, are available only as a combination medication (for example, hydrocodone with acetaminophen). When using combination medications that have acetaminophen, nurses must educate parents and caregivers about the maximum daily dose of acetaminophen for their child to prevent unintentional overdose. Nurses should explain to parents that some cold and flu OTC products contain acetaminophen.

I.V. opioids are used for children who can’t tolerate oral formulations and may be administered as an infusion or an intermittent I.V. push as needed. I.V. opioids also can be given via a patient-controlled analgesia (PCA) pump, which allows patients to safely and effectively administer small amounts of opioid within a specified time period. Some pediatric organizations also use PCA pumps for authorized agent-controlled analgesia. This modality allows authorized and educated nurses and/or caregivers to activate the PCA button for children who can’t do so themselves. A 2015 study by Czarnecki and colleagues showed this modality to be safe and effective, although it may not increase parent satisfaction.

Regardless of administration route, nurses should closely monitor children receiving opioids for side effects and adverse reactions, including increased sedation, which may be the first sign of impending opioid-induced respiratory depression. Nurses should take immediate action to decrease or stop the opioid per provider orders. Common opioid side effects include nausea, pruritus, drowsiness, and constipation. Managing side effects is key to patient comfort. If medications are needed to control side effects, the least sedating option should be used. (See Safe opioid use, storage, and disposal.)

Safe opioid use, storage, and disposal

Pediatric-pain-management-Safe-opioid-use-storage-disposal

Reducing opioid misuse requires appropriate use for pain control as well as safety precautions in the home.

Appropriate opioid use

In a study by Miech and colleagues, a legitimate opioid prescription predicted future opioid misuse in 12th grade students who had little experience with illegal drug use and strongly disapproved of marijuana use. This increased risk of future opioid misuse must be considered when weighing the risks and benefits of prescribing these medications to children. Opioids are appropriately indicated and necessary in some cases, but if pain can be adequately treated without them, they shouldn’t be prescribed. Nurses have a duty to discuss the risks and benefits of any treatment modality with patients and their families, and to inform providers of any identified risks.

Safe opioid storage and disposal

About 70% of the opioids misused by children are prescribed or obtained for free from a relative or friend. A study of U.S. Poison Control Centers by Allen and colleagues found that an average of 32 calls a day are received for unintentional opioid ingestion by children (more than 50% are age 5 years or younger).

When educating patients and families about opioid safety, nurses should include the following points:

  • Secure medications in a locked location. Many retail pharmacies sell medication lockboxes.
  • To ensure no medications are missing, keep a log of the number of opioids on hand and given to the child.
  • Be on the lookout for opioid seekers, including family members, friends, neighbors, and even strangers, who might want to steal unused medications from the home.
  • Transition from opioids to over-the-counter (OTC) pain medications when opioids are no longer needed. For many minor surgeries or injuries, OTC medications may be sufficient to manage pain.
  • Unused medications can be disposed of in a medication drop box using a medication disposal bag, taken to a drug take-back program, or disposed of in household trash after mixing them with undesirable substances such as coffee grounds or cat litter. Nurses can direct families to visit the U.S. Food and Drug Administration website for more information fda.gov/Drugs/ResourcesForYou/Consumers/BuyingUsingMedicineSafely/EnsuringSafeUseofMedicine/SafeDisposalofMedicines/ucm186187.htm.

Regional techniques. Regional anesthesia techniques—such as epidural catheters, spinal anesthesia, peripheral nerve catheters, para­vertebral catheters, and blocks—can improve postoperative pain control in children and reduce opioid use. Many of these techniques, which are being more widely used in the pediatric population, use local anesthetics and other medications that work directly on the nerves to help block the pain. Local anesthetics are nonsedating and have fewer side effects than opioid medications.

Procedural pain control. Critically ill infants experience between seven and 17 painful procedures per day during neonatal intensive care unit stay. A variety of local and topical anesthetics can be used in conjunction with nonpharmacologic pain management techniques to help comfort children during a procedure. Local anesthetic creams, patches, injections, or sprays should be offered to children before a painful procedure unless contraindicated. Involving parents or caregivers to help with comfort holds can help reduce stress and anxiety during a procedure.

Make a difference

Pain management in children continues to be suboptimal, but nurses can make a difference. Their individualized pain assessment using age-appropriate tools, administration of pharmacologic and nonpharmacologic pain treatments, optimal pain management advocacy, and patient and family education are key to relieving pediatric patients’ pain and improving their quality of life.        AN
