CRRT Complications Flashcards
1
Q
5 H’s
A
- Hypo/hypervolaemia
- Hypothermia
- Hypo/hyperkalaemia
- Harmorrhage
- Haemofilter
2
Q
3 I’d
A
- Ischaemia
- Intruder
- Infection
3
Q
Other complications
A
- acid base balance
- Electrolyte imbalance
4
Q
Hypovolaemia/hyportension cause
A
- May rise during treatment due to an underlying condition (trauma, sepsis, anaphylaxis, CS spine injury)
- Excessive flood removal.
5
Q
Hypervolaemia causes
A
- AKI due to oliguria/ fluid overload.
- Failure to remove adequate amount of fluid during treatment.
- Background infusions.
6
Q
Hypothermia causes
A
- Loss of body temperature via diffusion.
- Patient underlying condition (shock, fulminant hepatic failure)
7
Q
Hypo/hyper electrolyte imbalances
A
- Hypokalaemia = potassium restriction or large GI losses or over clearance via dialysate fluid.
- Hyperkalaemia = patient underlying condition (crush injuries, burns, academia), inadequate therapy rates, dialysate fluid or intravenous fluid.
8
Q
Hypophosphatemia causes
A
- Phosphate is retained by the body and renal failure and is not replaced by Ci-Ca or K2/K4.
- It causes muscle weakness and wasting = respiratory function compromise.
9
Q
Haemorrhage
A
- Excessive anticoagulation.
- Loss of platelets due to absorption and platelet destruction (heparin induced thrombopenia)
- Accidental disconnection.
- Loss of blood through circuit clotting therefore unable to return blood to patient
- Ruptured haemofilter
10
Q
Haemofilter (rupture)
A
To determine whether the kidney is ruptured check the effluent (waste) for blood with a dipstick. If blood is detected, it will indicate a ruptured kidney.
Disconnect the patient and do not return the blood
11
Q
Ischaemia
A
Femoral catheter has made predispose distal ischaemia
12
Q
Intruder (air emboli)
A
Air made into the CRRT circuit due to:
Lo loose connections vented caps on anticoagulation line, during connection disconnection phase.
13
Q
Infection
A
Due to essentially placed Quentin line = risk of developing infection
