  1. Nausea & Vomiting ‘made easy’

  2. First steps • What is the cause? • Non-medical treatment • Medical treatment • 1st line • Other options

  3. Scale of the problem • Occurs in 40-70% patients with advanced cancer • 1/3 will have more than 1 contributing factor • 1/3 will need more than 1 anti-emetic

  4. Non-medical treatment • Calm environment & good ventilation • Frequent small snacks • Avoid sight & smell of food eg cooking

  5. Gastric stasis - causes • Drugs • Opioids • ‘Squashed stomach syndrome’ • tumour, enlarged liver, ascites • Outflow obstruction • tumour

  6. Gastric stasis - symptoms • Epigastic discomfort • Fullness • Early satiety • Exacerbated by eating / relieved by vomiting • Large volume vomits (undigested food)

  7. Gastric stasis - management • Prokinetic agent metoclopramide 10-20mg tds (oral) 40-80/24hrs sc infusion • Also consider • Domperidone (less side effects but not sc) • PPI to reduce acidity • Steroids 8-12mg dexamethasone for 7 days • 2nd line • Cyclizine 50mg tds po/sc (150mg/24hrs sc infusion) bowel distension

  8. Chemically-induced nausea - causes • Drugs (10-30% on inititation of opioid) • antibiotics, anticonvulsants, antidepressants, cytotoxics, steroids, digoxin, NSAID’s • Metabolic • renal or hepatic failure, hypercalcaemia, hyponatraemia, ketoacidosis • Toxins • ischaemic/obstructed bowel, tumour effect, infection

  9. Chemically-induced nausea - symptoms • Constant nausea • Vomiting is variable in volume & timing • May be other features of drug toxicity

  10. Chemically-induced nausea - management • Haloperidol po/sc 1.5-3mg od/bd 2.5-10 mg/24hrs sc infusion • Also consider • Correct the correctable • Metoclopramide (gastric stasis) 10mg tds

  11. Raised intracranial pressure – causes • Intracranial tumour • Cerebral oedema • Intracranial bleed • Meningeal infiltration by tumour • Skull metastases • Cerebral infection

  12. Raised intracranial pressure – symptoms • Nausea worse in the morning • Headache • Nausea and/or vomiting provoked by head movement

  13. Raised intracranial pressure – management • Cyclizine 50mg tds (oral) 150mg/24hr sc infusion • Also consider • High dose steroid: dexamethasone 16mg od • Hyoscine hydrobromide • Kwells 300mcg qds • 0.8-3.6mg/24hr sc infusion

  14. If at first you don’t succeed… • Consider adding a second agent • Different mechanisms of action eg haloperidol with cyclizine • Avoid antagonistic action cyclizine counteracts the prokinetic affect of metoclopramide • Consider levomepromazine • ‘broad spectrum’ antiemetic • 6.25-12mg (1/4 -1/2 tablet)po or 5-25 mg sc/sc infusion over 24hrs

  15. Summary • Gastric stasis • metoclopramide • Chemically-induced • haloperidol • Raised intracranial pressure • cyclizine • Consider additional or 2nd line treatment • Don’t forget the effect of anxiety & pain
