10 Things You Need to Know About Pediatric Analgesia

Make a plan for treating pediatric pain that includes managing unfamiliarity and stress in both the patient and their parents or caregivers

The most complete definition of pain is “an unpleasant sensory and emotional experience associated with, or resembling that associated with, actual or potential tissue damage” (IASP). It is a highly complex and subjective condition in any patient.

With pediatrics, this complexity is intensified by the fact that paramedics don’t encounter pediatric patients as frequently, creating more unfamiliarity and stress. Challenges related to paramedic training and exposure to pediatrics often lead to myths and misconceptions. Here are 10 important things every provider should know about managing pain in children.

1. PEDIATRIC PAIN IS NOT WELL MANAGED

Pain is common in children, with more than a third of out-of-hospital pediatric patients complaining of pain. Two-thirds of that pain is described as intense or severe (Galinski et al 2010). Despite this, children often go without analgesia in the prehospital environment (Rutkowska & Skotnicka-Klonowicz 2015).

This trend is not limited to the prehospital environment. One study of emergency department patients with long bone fracture or burns showed that young age (6 months to 24 months) was associated with receiving no analgesia (Alexander & Manno 2003).

Poorly managed pain has consequences well beyond the patient’s time in the back of the ambulance. Alterations in brain development and stress response can persist throughout childhood, and even routine procedures in the very young can alter future pain perception (AAP 2015).

2. UNDERSTANDING PAIN IS ESSENTIAL IN TREATING PAIN

While there are many theories, the biopsychosocial model suggests that all illness has three major components (Engel). The model has direct applications to understanding and treating pain:

• The biology of pain includes things like tissue damage, inflammation and sensory nerve stimulus.
• The psychology refers to how a person understand the signals received from the nervous system.
• Socially, things like relationships and environmental stressors affect not just the pain experience but how it is expressed (Gatchel).
  
  

3. PAIN IS DIFFERENT IN CHILDREN

Age and level of development have important impacts on how pain is experienced by children. Biologically, there are big differences within the nervous system (especially in newborns). For example, newborns have a weaker inhibitory nervous system. In adults, this “turns down the volume” on noxious stimulus once it has been received by the brain.

Psychologically, a child’s ability to understand pain develops along with age and experience. Limited communication skills make describing pain more difficult. Socially, children rely heavily on parents and caregivers both for support as well as cues on how to navigate new situations.

4. AVOIDING PAIN IS THE FIRST STEP IN TREATING PAIN

The benefits of painful procedures such as blood glucose checks and IV starts require careful consideration. Will the procedure improve the care provided to the patient? Will deferring the procedure to the hospital put the patient at increased risk?

Children with a history of highly emotional responses to pain experience more distress during IV initiation and may benefit from having the procedure done in the more controlled environment within the hospital (McCarthy, et al 2010).

5. PAIN NEEDS TO BE ASSESSED TO BE TREATED

Being able to identify and quantify pain is important. The verbal numeric scale – “On a scale of 1-10, how bad is your pain?” – is a common tool for paramedics, but it may be developmentally inappropriate for younger children who can’t yet quantify their pain with a number.

In this case, a number of published tools, such as the Oucher and FACES scales, use pictures to help young children identify their level of pain. These tools are readily available and are easy to use (Principi 2018). A variety of scoring systems are also available to patients who are nonverbal due to either age or medical condition. If these tools are not readily available, a simplified VNS – “Are you having a little bit of pain or a lot of pain?” – is also an option. Parental perception of pain may also be helpful (von Baeyer, et al 2013).

6. TREATING ANXIETY IS AN IMPORTANT PART OF TREATING PAIN

The influence of anxiety on pain is incredibly complex, and it extends beyond the patient. One example of a simple approach to minimize this anxiety is the set of CARE principles shown in the table below (Lerwick 2016).

The higher the level of anxiety, the more the patient will benefit from intervention. Parent needs should also be addressed, as higher parental anxiety leads to a higher level of distress in children as well (McCarthy, et al 2010).

7. CONSIDER NON-PHARMACEUTICAL TREATMENTS

Basic comfort measures, such as bandaging, splinting and ice or heat, are available to every level of provider and should not be overlooked. Deep breathing, nonprocedural talk, humor and coping statements are beneficial when used by providers and parents alike during needle-related procedures (Campbell 2017). Distraction is also effective during painful procedures (McCarthy, et al 2010).

In neonates, a number of simple interventions have been well researched. Consider swaddling, providing a soother or allowing the baby to breastfeed during procedures such as IV starts. These interventions have demonstrated to reduce crying time and heart rate (AAP).

8. CONSIDER NON-NARCOTIC TREATMENTS

Pain that is refractory to initial treatment steps should be evaluated for non-narcotic analgesia. Broadly speaking, these fall into two categories: acetaminophen and non-steroidal anti-inflammatories (NSAIDs). Both classes of drugs provide analgesia, but through different mechanisms. For example, acetaminophen does not have the anti-inflammatory properties of NSAIDs. This means that acetaminophen can typically be given simultaneously with an NSAID to improve effectiveness.

In newborns, 24% oral sucrose has been extensively studied and provided two to four minutes of analgesia for use with painful procedures (AAP). It is often packaged in 1-2ml containers so that it can be administered one drop at a time. While these are not commonly found in the prehospital world, dextrose solutions of 20-30% could easily be prepared from an amp of D50W and are proven to have a similar effectiveness.

9. CONSIDER NARCOTIC TREATMENT OPTIONS

Commonly available narcotics include drugs like hydromorphone, morphine and fentanyl (Principi 2018). These strong opioids are generally reserved for moderate to severe pain, as they tend to have more immediate side effects.

As their name implies, narcotics generally provide analgesia as a result of their actions on opioid receptors. This class of drug is not better or worse than other forms of analgesia, it is just different. Pain relief can often be improved by combining narcotics with acetaminophen or NSAIDs.

10. HAVE A PLAN TO MANAGE PAIN

Having a stepwise approach to managing pain means treatment will be consistent and comprehensive:

1. Assess for the presence and severity of pain. This is necessary to both justify treatment as well as assess the effectiveness of interventions.
2. Consider non-pharmaceutical interventions. This includes addressing patient and family anxiety, as well as providing basic comfort measures. These options are available to all providers and are the initial steps of care for any child in distress. It is important to document these steps.
3. Consider non-narcotic interventions such as acetaminophen or NSAIDs.
4. Consider narcotic analgesia for patients with moderate to severe pain. This can be done simultaneously with the other steps, but it should never be done instead of the other steps.

Remember that the pain experience is much different for children than it is for adults. Just because the patient cannot or does not tell you about pain does not mean they aren’t experiencing it. But don’t be intimidated. Using these steps, you can effectively assess and manage your pediatric patients’ pain.
