A

<50 cm

17
Q

What are the 4 main surgical procedures that can cause small bowel syndrome?

A

Jejunostomy
Ileostomy
Jejuno-colic anastomosis

18
Q

What are the 2 types of venous access in parenteral nutrition?

A

Central
Peripheral

19
Q

How is peripheral PN feeding given?

A

Via a 22G blue cannula
This contains no lipids and reduced calories, so some oral or nasogastric feeding can be performed

20
Q

How is central PN feeding given?

A

This is inserted via a PICC, a tunnelled catheter or portocath via ultrasound

21
Q

What are PICC lines and where are they inserted?

A

Peripherally Inserted Central Catheter
Inserted into the arm and fed into the entrance to the right atrium

22
Q

What are the 2 types of tunnelled catheters and where are they inserted?

A

Subclavian - Into the subclavian vein
Hickman - Into the internal jugular vein

23
Q

Where are portacaths inserted?

A

They are inserted directly through the chest and into the right atrium

24
Q

What are some complications with catheter insertion?

A

Risk of sepsis, occlusion, displacement or breakage
Also requires immunosuppression

25
Q

What are some liver problems that can occur due to lack of use of the GI tract?

A

Liver steatosis
Fibrosis
Cirrhosis
Portal hypertension

26
Q

What are some gallbladder problems that can occur due to lack of use of the GI tract?

A

Cholelithiasis
Sludge
