Symptom Management - approach
What, where, why, exacerbating/relieving factors
Measurement of symptoms
Impact of symptoms
Which to treat first?
Reversible?
Aim – improve quality of life
Burden or benefit?

Factors to consider Abnormal physiology
- cachectic - organ failure (Renal) - multiple comorbidities
Polypharmacy – drug interactions
Route of administration
Priority – QoL vs survival

Breathlessness

Dyspnoea defined…
A subjective experience of breathing discomfort that consists of qualitatively distinct sensations that vary in intensity.
…. derives from interactions among multiple physiological, psyc
hological, social, and environmental factors and may induce secondary psychological and behavioral responses.’ ATS 1999

Non-pharmacological management

Evidence base?

Evidence for pharmacological rx
![Page 15: Dr. Mariam George - · PDF fileSymptom Management - approach What, where, why, exacerbating/relieving factors Measurement of symptoms Impact of symptoms Which to treat first?](https://reader033.vdocuments.us/reader033/viewer/2022052917/5a9e499b7f8b9a6a218d3758/html5/thumbnails/15.jpg)
Opiates ease dyspnoea without hastening death
Dampeners or modulators of a complex system, wherein a counterbalance is needed to offset particular response cascades
Patient goes to the loo Increased metabolic demand
High CO2 (metabolic stimulus) increases respiratory drive
![Page 16: Dr. Mariam George - · PDF fileSymptom Management - approach What, where, why, exacerbating/relieving factors Measurement of symptoms Impact of symptoms Which to treat first?](https://reader033.vdocuments.us/reader033/viewer/2022052917/5a9e499b7f8b9a6a218d3758/html5/thumbnails/16.jpg)
Facts…
Treat the treatable : consider Dexamethasone
Opiates - the only pharmacological intervention proven to provide relief
Nanodoses of opiates as small as 8mg cocodamol/ 0.5mg oramorph would help
Lorazepam useful only in acute panic moments – short term role.
Non-pharmacological measures better (unless dying)
Avoid fentanyl products

Cough
Treat the cause
Cancer - Chemo/RT Infection - Antibiotics/decongestant Post nasal drip - antihistamine/ steroids/ bronchodilator Reflux - PPI/ Prokinetic
Chronic cough > 8wks history
Wet cough: Aid expectoration to ease efforts - Steam inhalation / Physiotherapy - Expectorants : Saline nebs / Carbocisteine 750mg tds - Avoid cough suppressants unless poor sleep at night
Dry cough: Simple linctus, Antitussive - Codeine linctus (15-30mg, 3-4 x daily) / Morphine (2.5-5mg qds) - 2% Lidocaine 5ml Nebulized - Inhaled Sodium cromoglycate 10mg - Diazepam 5mg nocte

Haemoptysis 1/3rd lung cancer patients
Massive haemoptysis rare (3%)
SCC lying centrally or cavitating lesion
Rule out Clotting deficiency/disorder
Management: Radiotherapy (good response)
Oral tranexamic acid 1gm tds, continue for 1wk after bleed stops, then discontinue.
Stop if ineffective after a week.
Continue long term (500mg tds) only if recurrence.

Pain
An unpleasant sensory or emotional experience associated with actual or potential tissue damage or described in terms of such damage… (International Association for the Study of Pain) SUBJECTIVE

Pain
Careful assessment and diagnosis of cause
Drugs according to Analgesic Ladder
Persisting pain
SEEK SPECIALIST INPUT! Oncological or anaesthetic/surgical interventions

Management… 4/1/17: Screaming – IV diamorphine,
Oxycodone dose 15mg BD
5/1/17 : Agony, IM morphine, doubled Gabapentin;
5/1/17: My r/w: Advised not to twist, Oxynorm pre movement, Oxycontin, Gabapentin, Lorazepam instead of Diazepam, Oxycodone sc prn
7/1/17: Screaming - Medical team wanting to give Morphine/Abstral
Naproxen commenced
RT from 9th -12th, Oxycontin 30mg BD on d/c.

Pain management - Key points Counsel the patient from the onset
Pain diary/ drug chart
Lower doses if frail/elderly/renal impairment
One change at a time!
Parenteral administration
Transdermal patches
Pain + Nausea + Constipation +/- delirium
Always think – SIDE EFFECTS
Naloxone

In summary… Contextual history is key
Breathlessness, cough and pain
Complex physiology behind respiration
Non-pharmacological management in dyspnoea
Cough/ Haemoptysis /Pain
Gradual titration of Opiates
