PAIN IN PAEDIATRIC PATIENTS

INTRODUCTION

In the past, doctors thought that babies didnt feel much pain and hence didnt
suffer
However, we know today that children do feel pain (perhaps even more than
adults), and even premature babies can feel pain
Pain in children is often under-recognised and under treated
Nursing staff should be vigilant for pain assessing and recording
Pain in children needs to be addressed and treated adequately
If pain is not treated adequately, it can have a negative impact on the child
Hence, pain should be assessed as the 5th vital sign even in paediatric patients
However, pain assessment (including the tools used) is slightly different in
paediatric patients due to the different age groups

APPROACH TO ASSESSING PAIN IN CHILDREN

There are various ways to approach a child in pain and the suggested approach
for doctors are to using the acronym QUESTT.

Q Question the child

U Use pain rating scales
E Evaluate behavioural and physiological
S changes
T Secure the parents involvement
T Take the cause of pain into account
Take action and evaluate results

1. Question the child

- Health professionals are advised to listen and believe a childs description of
pain. Pain history is taken using the acronym:
o P : Place or site of pain
o A : Aggravating factors
o I : Intensity
o N : Nature and neutralizing factors

2. Use pain rating scales

- Children as young as 4 years can reliably report their pain. When choosing a
pain rating scale, one needs to consider not only the age but also the childs
developmental level, personality and condition. Do not only use the pain
scores in isolation and must take into consideration of parents accounts.

3. Evaluate behavioural and physiological changes

- Infants and young children may not be able to verbalise pain but changes in
behaviour eg. facial expression, body posture, activity, appearance) and
physiological parameters (heart rate, blood pressure, respiratory rate) can be
used as proxy measures for pain.
4. Secure the parents involvement
- It is important to involve parents as they often are able to accurately judge
their childrens pain. In addition, they can contribute in pain management.

5. Take the cause of pain into account

- Before starting any treatment, do consider simple correctable cause of pain
for example a tissued iv line.

6. Take action and evaluate the results

- do not ignore any complaints and action must always be taken. An action
might not necessarily be administering a drug but sometimes just simple
reassurance to parents or patients. You need to reassess the child after
every action.

WHEN SHOULD PAIN BE ASSESSED?

It is recommended that pain should be assessed under the following situations:

1. At regular intervals as the 5th vital sign
o Done when undertaking other routine assessments (other vital signs
like BP, heart rate, respiratory rate and temperature) to avoid
unnecessary distress or disturbance

2. At other times apart from scheduled observations if

o Unexpected intense pain occurs, especially if associated with altered
vital signs
o When indicators of pain are present in an otherwise previously pain
free child
o After procedures

WHO SHOULD BE ASSESSED?

Pain should be assessed in all paediatric patients in the following groups:

1. All inpatients in all medical and surgical wards(including various surgical
disciplines like orthopedics, ophthalmology etc)
2. All daycare patients

TOOLS FOR ASSESSING PAIN IN CHILDREN

The suggested tools for pain assessment in paediatrics are:

o 1 month 3 years : FLACC.

- this is a observational behavioural assessment and can be done by
observing the child for 2-5 minutes.
 o > 3 - 7 years : Wong-Baker FACES Pain Rating Scale
- this is a self report tool whereby a child is asked to choose a face
which best describes his pain. This is a simple and quick measure but
children can sometimes get confused with happiness measure.

o > 7 years : numerical scale

- this is a self report tool whereby the child is asked to rate his pain
based on a numerical scale whereby 0 is no pain, 10 is the worst
pain experience.

(refer Appendix 1,2,3,4)

GUIDELINES IN PAEDIATRIC PAIN MANAGEMENT

Key concepts in pain management 1

1. By the ladder
Enabling a stepwise approach to treatment commencing with non-opiods and
increasing to strong opioids (Refer WHO Analgesic ladder). The level at which a
child enters the ladder is determined by the childs needs, the intensity of pain
and response to previous treatment

2. By the clock
Regular scheduling ensures a steady blood concentration, reducing the peaks
and troughs of pro re nata (prn) dosing

3. By the appropriate route

Use the least invasive route of administration. The oral route is convenient, non
invasive and cost effective.

4. By the child
Individualise treatment according to the childs pain and response to treatment.

METHODS OF PAIN RELIEF

1) Medications

Paracetamol is the most commonly used analgesic for mild to moderate pain.
Oral paracetamol is better than rectal paracetamol because the absorption of
rectal paracetamol is slow and somewhat variable.
NSAIDs like Ibuprofen can be used for mild to moderate pain.
Children appear to have a lower incidence of renal and gastrointestinal side
effects when compared to adults even with chronic administration.
For a vast majority of children, opiods provide excellent analgesia with a wide
margin of safety.
Opiods should be normally be given via the oral or iv route in children. Avoid
intramuscular injections when possible as children might deny they are in pain to
avoid a shot.

Non-opiod analgesics
Paracetamol
Non steroidal anti-inflammatory drugs
Ibuprofen
Naproxen
Diclofenac
Meloxicam
Opiod analgesics
Weak opiod
Tramadol
Strong opiod
Pethidine
Morphine

(refer Appendix 5 & 6 for drug dosages)

2) Non Pharmacological interventions

a) Environmental factors
o Create a child friendly environment. Avoid bright lights or loud noisy places.

b) Other methods
Distractive techniques
o Use age appropriate distraction strategies. This teaches the child to focus on
something other than his pain.
Holding a familiar object (comforter) , such as pillow or soft cuddly toy
Singing; concentrating on nice things; telling jokes; games and puzzles
Blowing out air or bubbles
Reading pop-up books
Playing with a kaleidoscope or a 3D viewer
Breathing out (but not hyperventilating, which may increase anxiety and
induce venoconstriction)
Watching television or a video; playing interactive computer games
 Listening to stories or music (through headphones)

Guided imagery
o Teach the child to imagine that he is in his favourite place and doing his favourite
things.

Information
o Explain to the child what is going to happen during a procedure or surgery, this
might decrease his nervousness and understand the pain that he might feel.

Music and Dance

o Listening to music and dancing can ease the childs pain and take the childs
mind off his pain or illness.

Heat and cold packs

o Some types of pain are decreased by using heat whilst others might improve with
cold

Massage and physical therapy

o Massage, caress or stroking a child might make them more relaxed and soothe
their pain.

Wong-Baker FACES Pain Rating Scale

Explain to the child that each face is for a person who feels happy because he has no
pain (hurt) or sad because he has some or a lot of pain.
- Face 0 is very happy because he doesnt hurt at all.
- Face 1 hurts just a little.
- Face 2 hurts a little more.
- Face 3 hurts even more.
- Face 4 hurts a whole lot.
- Face 5 hurts as much as you can imagine, although you dont have to be crying to feel
this bad.

Ask your child to choose the face that best describes how he is feeling.
Mulitply the score obtained by a factor of 2 to make a total score out of 10.

PAIN AS THE FIFTH VITAL SIGN

Welcome to Hospital ! We understand that every admission to the

hospital is often a traumatic experience not only for the child but also for you as parents or
caregivers. For the child, it often means being in a different environment and having a whole
new range of experiences. There is often a lot of anticipation and fears of possible painful
experiences and the commonest include frequent procedures like blood taking and line
setting, or even an operation. You might worry if your child would be able to sleep or be
comfortable at all during their stay in hospital.

In the past, children especially small babies and infants were believed to be unable to
feel pain. However today we recognize that this is certainly not true and babies who are even
premature have been proven to have the capacity to feel pain. As such, we want to recognize
any pain in your child and to help them.

In order to ensure that your child obtains the best possible pain free hospital stay, we
will be measuring to see if your child is suffering from any pain at regular intervals. This
will be done when the nurses are taking other observations like the measuring heart rate or
blood pressure. We might also need to assess pain in your child under other circumstances for
example soon after an operation or if your child complains of pain. We will assess if your
child is in pain using several methods depending on your childs age. We will need your help
to get a response from your child and your opinion on your childs status.

After getting a pain score, we can then decide with you and/or your child whether any
further interventions or medications are required to make your child more comfortable. If you
have any questions or concerns about procedures or medications, please feel free to speak to
any of us. Help us to make your childs stay a pleasant and pain free one.

KESAKITAN SEBAGAI TANDA VITAL KELIMA

Selamat datang ke Hospital ! Kami memahami bahawa pengalaman

tinggal di hospital mungkin merupakan satu pengalaman yang kurang menyenangkan untuk
anak anda dan juga anda sekeluarga. Anak anda mungkin berasa resah-gelisah kerana dia
berada di dalam satu suasana yang amat berlainan daripada apa yang dia biasa alami.
Seringkali terdapat perasaan ketakutan ataupun kegelisahan kerana dia mungkin mengalami
prosedur-prosedur yang boleh mendatangkan kesakitan seperti pengambilan darah mahupun
memasukkan jarum ke dalam vena, ataupun mungkin satu pembedahan. Anda mungkin
berasa bimbang sama ada anak anda akan dapat tidur dengan lena ataupun berasa selesa
semasa dia berada di hospital.

Pada masa yang lalu, ramai pakar perubatan berpendapat bahawa kanak-kanak kecil
terutama bayi tidak berupaya untuk merasa kesakitan.Walaubagaimanapun, melalui
kemajuan di dalam bidang sains perubatan, kin terdapat bukti bahawa bayi termasuk yang
pramatang oun boleh merasai kesakitan. Oleh yang demikian, kami ingin mengenalpasti
sama ada anak anda mengalami sebarang kesakitan dan sekiranya ya, kami akan cuba
menolong anak anda menangani masalah ini.

Untuk memastikan supaya anak anda sentiasa selesa dan tidak mengalami sebarang
kesakitan semasa di hospital, kami akan mengukur tahap kesakitan anak anda dari masa ke
semasa. Pengukuran tahap kesakitan ini akan dilakukan pada masa-masa yang tertentu
apabila jururawat mengambil tanda-tanda vital yang lain seperti tekanan darah dan tahap
nadi. Kami juga mungkin perlu mengukur tahap kesakitan pada masa yang lain umpamanya
selepas prosedur dijalankan, selepas pembedahan ataupun bila anak anda mengadu kesakitan.
Kami akan mengukur tahap kesakitan dengan menggunakan beberapa kaedah yang berlainan
yang selaras dengan umur anak anda. Bantuan anda akan diperlukan di dalam proses ini
seperti menolong dalam mendapatkan respons dari anak anda ataupun memberi pendapat
anda tentang tahap kesakitan anak anda.

Selepas mendapat tahap kesakitan (pain score), kami akan membuat keputusan
bersama anda dan/ataupun anak anda sama ada sebarang ubat-ubatan ataupun kaedah lain
yang diperlukan untuk meningkatkan keselesaan anak anda. Sekiranya anda mempunyai
sebarang kemusykilan ataupun pertanyaan mengenai sebarang prosedur ataupun ubat-ubatan
anak anda, sila hubungi kami. Bantulah kami untuk memastikan anak anda sentiasa selesa
dan tidak mengalami sebarang kesakitan semasa di hospital
