Symptom control has to precede
spiritual support. A person can not
think about meaning of his life while
he has pain or keeps being sick.

that improves the quality of life
of patients & their families
facing the problems associated with
life-threatening illness,
through the prevention & relief of suffering
by means of early identification &
impeccable assessment & treatment
of pain & other problems,
physical, psychosocial and spiritual.

Palliative Care Principles
Symptom control
Disease
management
Psycho-social
care
• High quality
• Cost effective care
• Person oriented, not disease oriented
• Holistic in approach
• Multidisciplinary team
![Page 8: dr. Pongparade - Pain Management as Part of Palliative Care](https://reader035.vdocument.in/reader035/viewer/2022062317/5a6d0eec7f8b9a10428b4b19/html5/thumbnails/8.jpg)
Approach To Pain Control in Palliative Care
1. Thorough assessment by skilled and knowledgeable clinician
– History– Physical Examination
2. Pause here - discuss with patient/family the goals of care, hopes, expectations, anticipated course of illness. This will influence consideration of investigations and interventions
3. Investigations – X-Ray, CT, MRI, etc - if they will affect approach to care
4. Treatments – pharmacological and non-pharmacological; interventional analgesia (e.g.. Spinal)
5. Ongoing reassessment and review of options, goals, expectations, etc.

Symptom Management - General Approach
WHY is the patient having this symptom?
In the light of your assessment,Make a TREATMENT planTry to treat the cause at the same time as treating symptomatically
Liaise with the team, patient & familyExplain, educate and supportDocument discussion/decisions/plans
REVIEW / FOLLOW-UP
![Page 12: dr. Pongparade - Pain Management as Part of Palliative Care](https://reader035.vdocument.in/reader035/viewer/2022062317/5a6d0eec7f8b9a10428b4b19/html5/thumbnails/12.jpg)
Pain Assessment
• Listen carefully: What are the words used?
– May deny pain but will admit to having “discomfort”, “aching” or “soreness”
– Do you hurt anywhere?
– Are you uncomfortable?
– How does it affect you?
• Believe the patient “pain is what the patient says hurts….the best judge of a patient’s pain is the patient” Bonica
• Assess for other symptoms: Portenoy: Study of 243 cancer
patients- Average of 11.5 symptoms

PRINCIPLES OF SYMPTOM MANAGEMENT
– When possible, choose a drug treatment that targets the likely underlying cause
– Nausea and vomiting, for example, can be secondary to gastric outlet obstruction, hypercalcemia, increased intracranial pressure, esophagitis, opioid use, or constipation
Try to understand the pathophysiologybehind the symptom
![Page 14: dr. Pongparade - Pain Management as Part of Palliative Care](https://reader035.vdocument.in/reader035/viewer/2022062317/5a6d0eec7f8b9a10428b4b19/html5/thumbnails/14.jpg)
PAIN PROBLEMS HAS TO BE DIAGNOSED AND
DIFFERENTIAL DIAGNOSE
DInflammation from IV site
A Fracture from bone metastasis
B Pressure sore
CConstipation colic

What is the cause of this pain ? • Cancer-related
– Bone
– Nerve compression/infiltration
– Soft tissue infiltration
– Visceral
– Muscle spasm
– Lymphoedema
– Raised intracranial pressure
• Treatment related – surgery: postoperative scars
/adhesions
– Radiotherapy: burns/ fibrosis
– Chemotherapy: neuropathy
• Associated with cancer/ debility– Constipation
– Pressure sores
– Bladder spasms
– Stiff joints
– Post-herpetic neuralgia
• Unrelated to cancer– Arthritis
– Angina
– trauma

ExaminationIt is in itself a powerful, non-verbal message. “ I am interested in you, and this is how I am going to care for you.” and opportunity for
positive comments
( which need to be true)

The needs of the dying
are different from those
who are expected to recover.
When FANTASY stops, the reality begins…
Changed focus of care helps the person begin some of the tasks of life closure.

“When nothing can be done”
‘Caring is the result of an ongoing creativity process. If creativity is arrested or stopped, caring and hope are not possible. You have to restore creativity in order to restore hope”
![Page 29: dr. Pongparade - Pain Management as Part of Palliative Care](https://reader035.vdocument.in/reader035/viewer/2022062317/5a6d0eec7f8b9a10428b4b19/html5/thumbnails/29.jpg)
Clinically, skilled psychosocial and spiritual care can provide a way
out of pharmacologically “intractable” pain without resort
to sedation.

Causes of terminal restlessness
– Uncontrolled pain and other symptoms
– Drugs
– Metabolic
– Infections
– Constipation
– Cerebral causes
– Postictal
– Anxiety– Withdrawal
![Page 31: dr. Pongparade - Pain Management as Part of Palliative Care](https://reader035.vdocument.in/reader035/viewer/2022062317/5a6d0eec7f8b9a10428b4b19/html5/thumbnails/31.jpg)
Terminal sedation
• Sedation should not be intended as a terminal event
• All other options should have been explored first
• The level of sedation is only that required to relieve distress
• Sedation is achieved with sedatives, not opioid
![Page 32: dr. Pongparade - Pain Management as Part of Palliative Care](https://reader035.vdocument.in/reader035/viewer/2022062317/5a6d0eec7f8b9a10428b4b19/html5/thumbnails/32.jpg)
Effective pain management in terminally ill requires
• Understanding of pain control strategies
• Ongoing assessment
• Diagnosis of pain
• Breakthrough pain relief
• Fine adjustment of medications
• Opioid rotation
• Unresolved psychosocial or spiritual issue can be great impact to pain management
