Points to Cover • Steroids • Dose • Adverse effects • Counselling • Thromboprophylaxis • Laxatives
Steroids • Reduce inflammation around the tunour & cord oedema • Reduce pain • Preserve neurological function • Increase number of patients who remain ambulatory • High dose initially • Reduce rapidly • Where good results possible to stop steroid treatment completely
Choice and dose of steroid • Use dexamethasone • Dose is 16mg per day divided into 2 doses (N.B.= approx 100mg prednisolone) • Trials compared 16mg per day with 96mg per day showed more side-effects with higher dose • Give after Breakfast and Lunch. • Reduce dose over 2 weeks • can cause problems if stopped suddenly. • If symptoms worsen increase dose/reduce more slowly. • Some patients may be on maintenance steroids.
Adverse Effects • Gastric irritation • Take after food. • PPI cover • Lansoprazole 15mg OD • Only for the duration of the steroids. • Increased Appetite • Impaired glucose tolerance • Mood disturbances • Fluid retention
Long-term adverse effects • Osteoporosis • Muscle weakness • Reduced healing/ability to fight infection • Care around people with chicken pox/ measles/influenza • Glaucoma • Impaired healing • “Cushing’s Syndrome”……
Points to remember • Take steroids with or after food • Avoid take steroids later than 4pm • Dexamethasone can be dispersed in water & given via PEG/NG (off license) • Dexamethasone liquid is available • If the patient has had other courses of steroids in the last year they may need to reduce the dose more slowly • Avoid contact with anyone with suspected chicken pox or shingles. • Check the patient understands how to reduce their dose.
Thromboprophylaxis • Active Cancer • Reduced Mobility • Inpatient hospital stay = VTE Risk • Prescribe thromboprophylaxis unless contra-indicated. • Consider if thromboprophylaxis is indicated on discharge – immobility?
Laxatives • Constipation often associated with mSCC • Can be one of the presenting symptoms • Maintaining regular bowel action is important for patient comfort • Psychological issues also need to be overcome e.g. patients embarrassment at needing to be assisted with toileting
Laxatives • Oral laxatives may be ineffective or inappropriate • Reflex bowel • Patient has little/no awareness of bowel fulness • Reflex function of the rectum remains • Fast acting rectal measures most appropriate • Bisacodyl suppositories or sodium citrate enemas (15-30mins to effect) • If hard stools, glycerol suppository • Flaccid bowel • May need digital removal • No laxatives recommended
