Clinical Presentations II Flashcards
How is an acute GI bleed managed
Hx - pain, associated symptoms, run up to the bleed, PMH (alcohol and reflux), D+A
Airway - speak to patient, check in mouth, suction if required, triple airway manouvure, lay in recovery position if vomiting
Breathing - listen, look and feel, listen to chest and look for equal expansion, resp rate, non-rebreathe 15 litres, saturations
Circulation - HR, ECG, two wide bore cannulas with IV access and bloods (including G+S and cross match and clotting) taken off the back, listen to chest, fluid challenge if shock, ABG
Disability - glucose, eyes, quick neuro exam and GCS
Exposure - remove all clothing, check temp, look for rash, abdo exam quickly (peritonitis, bowel sounds, PR exam)
Urgent call for senior and endoscopist. Might need terlipressin IV then ligation in endoscopy. Might need an IV PPI. Propranolol prophylactic. Stop NSAIDs and blood thinners. Might need colonoscopy if from lower end. Will have upper scope if large lower GI bleed as can be from upper GI.
What are the life threatening causes of upper GI bleeds
Peptic ulcer
Vascular malformations
Varices
Upper GI malignancy
What is the scoring system for upper GI bleeds
Rockall risk scoring system - need endoscopy to complete scoring.
Causes of lower GI bleeds
Upper GI bleeds
Diverticulitis
Colorectal cancer
Angiodysplasia
haemorrhoids
Bowel ischaemia
Anal fissure
IBD
How to manage chronic GI bleeding
Hx - when it started, pain, associated symptoms, abdo tenderness, cachexic, pale, PR exam, weight loss
Ix - FIT test, bloods, colonoscopy and endoscopy, stool sample, (small bowel - video capsule endoscopy)
Rx - treat anaemia (ferrous sulphate) and investigate cause
How to manage haemorrhoids
Hx - bowel habits, pain, associated symptoms, abdo tenderness, PR exam
Ix - clinical
Rx - high fibre diet, anusol, laxatives, band ligation if resistant, haemarrhoidectomy if needed
Strangulated - cant sit down and very painful consider haemorrhoidectomy and conservative management in the meantime.
How to manage anal fissures
Hx - bowel habits pain, associated symptoms (fever for abscess), abdo exam, inspection (cannot manage PR exam, may have discharge),
Rx - high fibre diet, lidocaine, laxatives, GTN
How to manage angiodysplasia
Hx - blood in stools and PR but no abdo pain
Ix - positive FIT, colonoscopy may be negative, capsule endoscopy
Rx - angiographic emblisation or argon plasma coagulation
How to manage nausea and vomiting
Hx - ask about fever, pain, headache, dizziness (labyrinthitis), bowel obstruction, alcohol/drugs, visual issues, haematemesis or malena, full set of obs, D+A and PMH
Ix- fluid status, abdo exam for hernias and bowel movement, AXR, ECG, routine bloods, ABG (if acute), CT head if brain trauma
Rx - treat cause, antiemetics and fluids
How to manage diarrhoea
Hx - ask about pain, fever, blood in stools, length of time, diet, recent travel, stress, immunosuppression, PMH, D+A
Ix - fluid status, obs, abdo exam, PR, stool sample (C diff and MCS), routine bloods, AXR if obstructed picture
Rx - increase fluids, analgesia, review meds, stool chart, isolate if C.diff, find cause
Drugs that cause diarrhoea
Abx
Laxatives
Colchicine
NSAIDs
Digoxin
Iron
Ranitidine
Thiazide diuretics
Propranolol
PPIs
Causes of N+V
DKA
Stomach bug
Raised ICP
Acute abdomen
Ileus
Bowel obstruction
Gastroenteritis
Labyrinthitis
Migraine
Hyperemesis gravidarum
Drug induced
How is infective gastroenteritis managed
Hx - pain, recent food, diarrhoea, vomiting, fever, family members, PMH, D+A, recent travel
Ix - obs, fluid balance, stool sample (MCS and C.diff), routine bloods
Rx - usually supportive but may be given oral rehydration therapy with abx in hospital
How is pseudomembranous ulcerative colitis managed
Hx - pain, fever, dysentery, vomiting, fluid intake, PMH,D+A (especially C antibiotics), usually greeny watery stools
Ix - Obs, fluid balance, routine bloods, stool culture (MCS and C.diff)
Rx - fluids, analgesia, patient isolation!, metronidazole IV and vancomycin oral. Fidazomicin if that doesnt work
How is IBS managed
Hx - pain, diarrhoea, constipation, stress, oral intake, pattern, normal exam
Ix - routine bloods plus calcium and magnesium, faecal calprotectin, TGAA antibodies, TFTs
Rx - diagnosis of exclusion. Reassure, FODMAP, buscopan, and loperamide, SSRI/amitriptyline are second line
How is coeliac disease managed
Hx - abdo pain, bloating, dermatitis herpetoformis, diarrhoea, steatthorea, weight loss, mouth ulcers, sore tongue (B12 deficiency)
Ix - TGAA, duodenal biopsy, folate, b12, RBC, Iron
Rx - gluten avoidance
How is IBD managed
Hx - abdo pain, diarrhoea, bloody stools, fever, weight loss, mouth ulcers, sore joints, pyoderma gangrenosum, abdo obstruction, erythema nodosum, clubbing
Ix - routine bloods, stool culture, faecal calprotectin, b12 (terminal ileal disease), AXR (obstruction), colonoscopy
Rx - depends if UC or crohns, rehydrate, pain relief and correct electrolyte imbalances
Differences between crohns and UC
Crohns - no blood or mucus, entire length of gut, skip lesions, thickness (full), smoking is RF
UC - Continuous inflammation, limited to colon, only superficial, smoking is protective, continuous blood or mucus, use aminosalicylates, PSC
How is UC managed
Mild - oral +/- rectal mesalazine
Moderate/severe - prednisalone
Recovery - mesalazine
Surgery - toxic megacolon or failure to respond to max medical therapy after 5-7 days.
How is Crohns managed
Mild - pred
Moderate/severe - hydrocortisone IV
Recovery - pred/azathioprine
Surgery if strictures or abscesses but never curative
How is constipation managed
Hx - not passing stool, bloating, loss of appetite, pain, hard stool on PR, can ask about hypercalaemia (headaches, stones) and hyperthyroidism (depression, weight gain, heat intolerance), ensure no obstruction (passing wind, no vomiting, abdo pain, shock), if over 40 think MALIGNANCY (weight loss, blood etc)
Ix - fluid balance, drugs review, PR, U+Es, FBC, calcium and magnesium, TFTs if refractory
Rx - Laxatives, increase fluids, ensure eating, fix electrolyte imbalances, reduce opioids, get up and moving. Laxatives- bulk-forming laxative and then add in osmotic then if still difficult to pass add in stimulant. Phosphate enemas are last line. Use osmotic or stimulant if opioid induced.
Medications that induce constipation

Circulation - HR, ECG, two wide bore cannulas with IV access and bloods (including G+S and cross match and clotting, paracetamol levels, viral serology) taken off the back, listen to chest, fluid challenge if shock, ABG
Disability - glucose, eyes, quick neuro exam and GCS
Exposure - remove all clothing, check temp, look for rash, abdo exam quickly (peritonitis, bowel sounds, PR exam)
Call for senior help and reassess ABCDE, investigate with fibroscan, the above blood results and an USS abdo and ascitic tap
Long-term - abx, daily bloods, steroids, lactulose, HDU/ICU
Causes of acute liver failure
Acute - paracetamol overdose, alcoholic hepatitis, Hep B, Hep C, autoimmune hep, ischaemic hepatitis (HF and shock)
