Triad of nephrotic syndrome? Consequence?
- Proteinuria (> 3g/24hr) causing
- Hypoalbuminaemia (< 30g/L) and
- Oedema
Loss of antithrombin-III, proteins C and S and an associated rise in fibrinogen levels predispose to thrombosis. Loss of thyroxine-binding globulin lowers the total, but not free, thyroxine levels.
Stomas?
- In emergency when the bowel has perforated the risk of an anastomosis is much greater, particularly when the anastomosis is colon-colon.
- End colostomy is often safer and can be reversed later.
- Resection of the sigmoid colon + formation of end colostomy = Hartmans procedure.
- Whilst left sided resections are more risky, ileo-colic anastomoses are relatively safe even in the emergency setting and do not need to be defunctioned.

Starting on warfarin?
- Decide on target INR and duration of therapy
- Consider need for bridging LMWH until INR in target range
- Decide on loading regime
- Standard = 10 mg
- Sensitive - >65 years, ↑baseline INR, cardiac failure, liver disease, nutritional deficiencies, body weight <50kg, etc = 5mg
- Measure INR daily
- Prescribe warfarin based upon INR measurements

What to do when INR is too high and minor bleeding? (epistaxis, haematoma)

What to do if INR too high and major bleeding?
(intracranial, GI bleeding, intraocular, pericardial bleeds, compartment syndrome, shock)
- Stop warfarin
- Re-start when INR <5.0
- IV vitamin K 5-10mg
- Prothrombin complex concentrate (PCC)
What is prothrombin complex concentrate?
AKA: PCC, octaplex
- Produced by fractionation of pooled plasma from non-UK donors
- Contains factors II, VII, IX and X
- IV infusion
- Re-check clotting 20 minutes after injection
3ml/min via syringe driver (10 ml/min if life threatening)
How to monior unfractionated heparin?
APTT
Name some combination insulins?
Humalog Mix50 and Humalog Mix25
Long-acting mixed with a bit of rapid-acting
How to prescribe regular insulin?
- Name of insulin & brand name
- Type of device
- Exact time & units to be given
- Then simply sign!
