Chapter 4 - management of physical symptoms Flashcards
what are some measures to assess performance status?

4) Views on care
5) Barthel index
6) carer measures
what are the 5 phases of illness?
stable unstable deteriorating dying deceased
what is “stable” phase of illness?
Phase where the patients problems and symptoms are adequately controlled by the established plan of care AND further interventions to maintain control and quality of life have been planned AND family/carer situation is relatively stable with no issues apparent
what is the unstable phase of illness?
an urgent change in the plan of care or emergency treatment is required BECAUSE the patient now experiences a new problem that was not anticipated in the original plan and/or the patient experiences a paid increase in the severity of an existing problem and/or the family’s/carers circumstances suddenly change impacting on patient care
what is the deteriorating phase?
the care plan is addressing the patients needs however they require periodic review because the patients overall functional status is declining, and the patient experiences worsening of existing problems and/or the patient experiences a new but anticipated problem and/or the family/carer experience gradual worsening distress that impacts on the patient care
what is the dying phase
death is expected within days
when does the stable phase end?
when the needs of the patient and/or carer increase requiring changes to the existing plan
when does the unstable phase end?
the new plan of care is in place, it has been reviewed and no further changes are required. This does not mean the symptoms/crisis has fully resolved, but there is a clear diagnosis and place of care, AND/OR the death is likely within days
when does the deteriorating phase end?
patient condition has plateaued, or there is an urgent charge in the care plan or emergency treatment, AND/OR family/carers experience a sudden change in their situation that impacts on patient care and urgent intervention is required OR death is likely within days

what are the four types of laxatives?
stimulant
osmotic
faecal softeners
opioid antagonists
what are some examples of stimulant laxatives and how do they work?
Senna

they both rely on bacterial transformation in the large bowel to produce active derivatives and so have little small bowel effect
when should stimulant laxatives be avoided?
intestinal obstruction
give some examples of osmotic laxatives, and explain how they work?
lactulose
movicol/laxido
phosphate enemas
magnesium salts
they are not absorbed from the gut, and they increase water in the lumen by osmotic action, leading to increase in volume and stimulation of the gut wall, causing peristalsis and expulsion of faeces

sodium docusate
glycerol supps
poloxamer
reduce surface tension and improve water penetration of stools
how do you manage faecal impaction?
bisacodyl supps (must be in contact with rectal mucosa)
naloxegol

more than 3 unformed stools in 24 hours
what are common causes of diarrhoea in palliative care setting?
imbalance of laxatives drugs - antacids, NSAIDs, iron preparations, antibiotics C diff faecal impaction - overflow radiotherapy involving abdomen or pelvis (most commonly in 2nd or 3rd week) pancreatic cancer - malabsorption gastrectomy colectomy colonic/rectal tumour endocrine tumours which secrete hormones causing diarrhoea i.e. carcinoid tumour diets high in fibre ibs/ibd
what does pale fat smelly stools suggest?
malabsorption - pancreatic or illeal disease
what does alternating diarrhoea and constipation suggest?
poor laxative therapy
