Torment Management In Palliative Care Mike Harlos MD, CCFP, FCFP Professor and Section Head, Palliative Medicine, University of Manitoba Medical Director, WRHA Palliative Care Medical Director, Pediatric Symptom Management Service

Slide 2

Pain An offensive tangible and enthusiastic experience connected with genuine or potential tissue harm, or depicted as far as such harm. Worldwide Association for the Study of Pain

Slide 3

Clinical Terms For The Sensory Disturbances Associated With Pain Dysesthesia – An unpalatable irregular sensation, whether unconstrained or evoked. Allodynia – Pain because of a boost which does not ordinarily incite agony, for example, torment brought about by light touch to the skin Hyperalgesia – An expanded reaction to a jolt which is regularly excruciating Hyperesthesia - Increased affectability to incitement, barring the extraordinary faculties. Hyperesthesia incorporates both allodynia and hyperalgesia, yet the more particular terms ought to be utilized wherever they are material.

Slide 4

Approach To Pain Control in Palliative Care Thorough appraisal by gifted and learned clinician History Physical Examination Pause here - talk about with patient/family the objectives of consideration, trusts, desires, foreseen course of sickness. This will impact thought of examinations and intercessions Investigations – X-Ray, CT, MRI, and so on - in the event that they will influence way to deal with consideration Treatments – pharmacological and non-pharmacological; interventional absense of pain (e.g.. Spinal) Ongoing reassessment and audit of choices, objectives, desires, and so on

Slide 5

Visceral Somatic bones, joints connective tissues muscles Organs – heart, liver, pancreas, gut, and so forth. Deafferentation Sympathetic Maintained Peripheral TYPES OF PAIN NEUROPATHIC NOCICEPTIVE

Slide 6

Somatic Pain Aching, frequently steady May be dull or sharp Often more terrible with development Well restricted Eg/Bone & delicate tissue mid-section divider

Slide 7

Visceral Pain Constant or crampy Aching Poorly confined Referred Eg/CA pancreas Liver container distension Bowel check

Slide 8

FEATURES OF NEUROPATHIC PAIN

Slide 9

Pain Assessment

Slide 10

"Depicting torment just regarding its power resemble portraying music just as far as its clamor" von Baeyer CL; Pain Research and Management 11(3) 2006; p.157-162

Slide 11

PAIN HISTORY Description: seriousness, quality, area, fleeting elements, recurrence, irritating & reducing components Previous history Context: social, social, enthusiastic, profound elements Meaning Interventions: what has been attempted?

Slide 12

Example Of A Numbered Scale

Slide 13

Medication(s) Taken Dose Route Frequency Duration Efficacy Adverse impacts

Slide 14

Physical Exam In Pain Assessment Inspection/Observation "You can watch a great deal just by watching" Yogi Berra Overall impression… the "gestalt"? Outward appearance: Grimacing; wrinkled temples; seems restless; level influence Body position and unconstrained development: there might position to secure excruciating zones, restricted development because of torment Diaphoresis – can be brought about by torment Areas of redness, swelling Atrophied muscles Gait Myoclonus – perhaps showing opioid-instigated neurotoxicity

Slide 15

Physical Exam In Pain Assessment Palpation Localized delicacy to weight or percussion Fullness/mass Induration/warmth

Slide 16

Physical Exam In Pain Assessment Neurological Examination Important in assessing torment, because of the likelihood of spinal line pressure, and nerve root or fringe nerve sores Sensory examination Areas of deadness/diminished sensation Areas of expanded affectability, for example, allodynia or hyperalgesia Motor (quality) exam - alert if hard metastases (may crack) Deep ligament reflexes – force, symmetry Hyperreflexia and clonus: conceivable upper engine neuron sore, for example, spinal line pressure or cerebral metastases. Hyoporeflexia - conceivable lower engine neuron hindrance, including sores of the cauda equina of the spinal rope or leptomeningeal metastases. Sacral reflexes – reduced rectal tone and truant butt-centric reflexes may demonstrate cauda equina contribution of by tumor

Slide 17

Physical Exam In Pain Assessment Other Exam Considerations Further regions of center of the physical examination are controlled by the clinical presentation. Eg: assessment of pleuritic mid-section torment would include a point by point respiratory and mid-section divider examination.

Slide 20

3 By the 2 Clock 1 W.H.O . Pain relieving LADDER Strong opioid +/ - adjuvant Weak opioid +/ - adjuvant Pain continues or expands Non-opioid +/ - adjuvant

Slide 21

STRONG OPIOIDS most normally utilize: morphine Hydromorphone (Dilaudid ®) transdermal fentanyl (Duragesic®) oxycodone Methadone DO NOT utilize meperidine (Demerol â ) long haul dynamic metabolite normeperidine ® seizures

Slide 22

OPIOIDS and INCOMPLETE CROSS-TOLERANCE change tables expect that resilience to a particular opioid is completely "traversed" to different opioids. cross-resilience flighty, particularly in: high measurements long haul use separate figured dosage in ½ and titrate

Slide 23

TITRATING OPIOIDS measurement increment relies on upon the circumstance measurements ­ by 25 - 100% EXAMPLE: (measurements in mg q4h)

TOLERANCE PSYCHOLOGICAL DEPENDENCE/ADDICTION PHYSICAL DEPENDENCE

Slide 28

TOLERANCE A typical physiological wonder in which expanding measurements are required to deliver the same impact Inturrisi C, Hanks G. Oxford Textbook of Palliative Medicine 1993: Chapter 4.2.3

Slide 29

PHYSICAL DEPENDENCE An ordinary physiological wonder in which a withdrawal disorder happens when an opioid is unexpectedly suspended or an opioid opponent is controlled Inturrisi C, Hanks G. Oxford Textbook of Palliative Medicine 1993: Chapter 4.2.3

Slide 30

PSYCHOLOGICAL DEPENDENCE and ADDICTION An example of medication use portrayed by a kept needing for an opioid which is show as habitual medication looking for conduct prompting a staggering contribution in the utilization and obtainment of the medication Inturrisi C, Hanks G. Oxford Textbook of Palliative Medicine 1993: Chapter 4.2.3

Slide 31

Changing Route Of Administration In Chronic Opioid Dosing po/sublingual/rectal courses SQ/IV/IM courses decrease by ½

Slide 32

Using Opioids for Breakthrough Pain Patient must feel in control, enabled Use forceful measurements and interim Patient Taking Short-Acting Opioids: 50 - 100% of the q4h dosage, given q1h prn Patient Taking Long-Acting Opioids: 10 - 20% of aggregate every day dosage given, q1h prn with short-acting opioid planning

Slide 33

Opioid Side Effects Constipation – need proactive diuretic use Nausea/retching – consider treating with dopamine opponents and/or prokinetics (metoclopramide, domperidone, prochlorperazine [Stemetil], haloperidol) Urinary maintenance Itch/rash – more awful in kids; may require low-measurements naloxone imbuement. May attempt antihistamines, however not awesome achievement Dry mouth Respiratory sorrow – remarkable when titrated because of side effect Drug communications Neurotoxicity (OIN): wooziness, myoclonus ® seizures

Slide 35

Delirium Hyperalgesia Opioids Increased Agitation Opioids Increased Misinterpreted as Disease-Related Pain Misinterpreted as Pain Spectrum of Opioid-Induced Neurotoxicity Opioid resistance Mild myoclonus (eg. with resting) Seizures, Death Severe myoclonus

Slide 36

OIN: Treatment Switch opioid (pivot) or diminish opioid measurement; typically much lower than anticipated dosages of exchange opioid required… frequently utilize prn at first Hydration Benzodiazepines for neuromuscular excitation

Slide 37

Adjuvant Analgesics initially created for non-pain relieving signs along these lines found to have pain relieving action in particular agony situations Common uses: torment ineffectively receptive to opioids (eg. neuropathic torment), or with expectations of bringing down the aggregate opioid measurement and in this manner alleviate opioid reactions.

Slide 38

Adjuvants Used In Palliative Care General/Non-particular corticosteroids cannabinoids (not yet usually utilized for agony) Neuropathic Pain gabapentin antidepressants ketamine topiramate clonidine Bone Pain bisphosphonates (calcitonin)

Slide 39

CORTICOSTEROIDS AS ADJUVANTS ¯ aggravation ¯ edema ¯ unconstrained nerve depolarization } ¯ tumor mass impacts

Slide 40

CORTICOSTEROIDS: ADVERSE EFFECTS

Slide 41

DEXAMETHASONE negligible mineralcorticoid impacts po/iv/sq/?sublingual courses maybe can be given once/day; regularly given all the more as often as possible If an intense course is stopped inside 2 wks, adrenal concealment not likely

Slide 42

Treatment of Neuropathic Pain Pharmacologic treatment Opioids Steroids Anticonvulsants – gabapentin, topiramate TCAs (for dysesthetic torment, esp. in the event that dejection) NMDA receptor adversaries: ketamine, methadone Anesthetics Radiation treatment Interventional treatment Spinal absense of pain Nerve pieces

Slide 43

Gabapentin Common Starting Regimen 300 mg hs Day 1, 300 mg offer Day2, 300 mg tid Day 3, then progressively titrate to impact up to 1200 mg tid Frail patients 100 mg hs Day 1, 100 mg offer Day 2, 100 mg tid Day 3, then slowly titrate to impact

Slide 44

Incident Pain happening as an immediate and quick result of a development or action

Slide 45

Circumstances In Which Incident Pain Often Occurs Bone metastases Neuropathic torment Intra-abd. malady irritated by breath "occurrence" = breathing cracked viscus, peritonitis, liver discharge Skin ulcer: dressing change, debridement Disimpactio
