Random Flashcards
Describe the presentation of DIC
Severely unwell patient eg. sepsis, burns, trauma
Bleeding from everywhere: lines, eyes, ears, mucous membranes
Describe the investigation results in DIC
Abnormal clotting ^ APTT ^ PT ^ D-dimer Low platelets Low clotting factors
Describe the management of DIC
Treat cause
Replace clotting factors: cryoprecipitate, FFP
Describe the presentation of tumour lysis syndrome
Electrolyte abnormalities in patients receiving chemotherapy (specifically haem malignancies)
- High K+
- High urate
- High phosphate
- Low Ca
-> AKI, arrhythmia + cardiac arrest, seizures
Describe the management of tumour lysis syndrome
A to E approach
- IV fluids
- Manage hyperkalaemia: eg Ca gluconate, insulin
- Stop nephrotoxic drugs
- Phosphate binders eg. Aluminium salts
Describe the prevention of tumour lysis syndrome
Lots of fluids
Allopurinol
Describe the causes of upper GI bleeding
Peptic ulcer disease, erosions Mallory Weiss tear Oesophagitis Varices Drugs: NSAIDs, anticoagulants Malignancy Boerhave's perforation
Describe the presentation of upper GI bleeding
-Haematemesis, melaena, pain
-Fe deficiency: fatigue, SOB, reduced exercise
-Blood loss: dizziness, syncope, shock
+/- signs of chronic liver disease
What scoring systems can be used with upper GI bleeding?
Glasgow-Blatchford bleeding scale: characterises patients as high and low risk to determine admission
-Takes into account: Hb, urea, BP + HR, history of melaena/syncope/liver disease/heart failure
Rockall score: risk stratification for rebleeding risk + mortality
-Takes into account age, obs, comorbidities, endoscopy findings
Describe the initial management of upper GI bleeding
A to E approach
A: protect airway
B: high flow O2
C: IV acces with 2 large bore cannulae, take bloods (FBC, U+Es, LFTs, clotting, G+S)
-Give IV fluids while waiting for blood products
-Insert catheter, measure urine output
Further:
- Stop anticoagulation
- CXR, ECG, ABG
- Correct clotting abnormalities
- If variceal: IV terlipressin 2mg/6 hours
- IV antibiotics eg. Tazocin, erythromycin
- Endoscopy + haemostasis (clips, cautery, adrenaline)
-> continue to monitor for rebleed
