Why is assisted feeding important if an animal hasn't eaton in 12-24 hours?
the intestinal villi will start to die this will reduce the absorptive rate of any food
118
Why is it important to not let an animal gorge on food if for whatever reason they haven't eaton in a couple days? (e.g. locked in a shed) (2) - explain the first one
they can develop re feeding syndrome where a surge in insulin and rapid change in hormones causes severe clinical signs they are at risk of developing fatty liver disease especially if they've been starved
119
When is an animal classed as Anorexic? - Give and explain an example of anticipated anorexia
where an animal does not eat for 12-24 hours post jaw surgery - we can anticipate that the animal will not want to or be able to eat for a few days
119
State 6 reasons for considering assisted feeding
anorexia anticipated anorexia concerns regarding weight loss or malnutrition increased losses increased requirements bypass precipice areas of GI tract
120
Give an example of what we mean by "increased losses" - Give examples of how these losses can occur (4)
protein loss burns renal disease liver disease chronic diarrhoea
121
Give examples of when an animal has 'increased requirements' (2)
sepsis extensive wound healing
122
Do we bypass healthy bits of the GI tract or just broken sections of the GI tract?
just the broken sections as they heal
123
It is well documented that early attention to nutrition may avoid complications associated with reduced calorie intake, shorten hospitalisation times and aid recovery
123
Should we syringe feed? - why (2)
no force feeding can cause food aversion rabbits are at a higher risk of aspiration due to the stress of syringe feeding
124
When hand feeding: - Where is best to avoid hand feeding patients? - why
in their kennel this is their safe, relaxation and sleep zone so hand feeding them here can cause stress and food aversions
125
State the 3 main types of Assisted Feeding Tubes
nato-oesophageal oesophagostomy percutaneous endoscopic gastronomy
126
Naso-oesophageal Tubes: Describe its placement - Where is it usually best to stop the end of the tube and why? - Is it well tolerated? - Is any anaesthetic required? if so, where
the tube is passed into the nose into the back of the oropharynx into the oesophagus before the cardiac sphincter to avoid oesophagitis from gastric acid splashing into oesophagus yes local anaesthetic on the nose
127
Naso-oesophageal Tube: - How long can it stay in place? - What should we do if the animal still needs assisted feeding after this timeframe? - Is it expensive? Why? - Can the animal be sent home with it in? - What is the main risk?
3-5 days consider switching to a different type of tube relatively cheap because only a small amount of local anaesthetic is used Yes if the owner is well educated it can become dislodged and lead food into the trachea
128
Oesophagostomy: - How is this tube placed? - How long can it be left in? - is it well tolerated? - Is it expensive? Why?
the tube enters the oesophagus through an incision on the left hand side of the neck 3-4 weeks generally more expensive than an NO tube as general anaesthetic is required to place it
129
Oesophagostomy: - Can animal we sent home with it in? (2) - How does the tube size compare to a NO tube? - What is the biggest risk with this type of tube?
yes if the owner is well taught and able to keep incision site clean and change dressings bigger tube so can feed more infection
130
PEG Tube: - How is this tube placed? - Is anaesthetic required? - What is the delay between tube placement and being able to use it? - Why is there a delay? - How long can it be left in place?
it is placed into the stomach through an incision in the body wall yes general anaesthetic is required 7-14 days to allow time for the tube to heal into the body wall to minimise the risk of stomach juices leaking into the abdominal cavity months
131
PEG Tube: - Can the animal go home? - Give an example of a disorder you would use this tube to treat - What is the advantage in terms of type of food for this tube over the other 2? - Why is it so expensive? (3)
yes the owner must be taught how to use it megaoesophagus this tube is wider so can accommodate most types of food blended up general anaesthetic used more equipment required to place it more technically demanding procedure
132
State the name of the 4th type of assisted feeding tube that is less commonly used.
enterostomy tube
132
What foods can we use in the tubes? (3)
liquid foods specific clinical liquid diets critical care diets
133
How can we calculate how much food to feed the patient? - Can very liquid food be administered another way? - What does the decided feeding regime need to fit around? (2)
calculate the RER of the patient find the kcal per ml of the food you are using give 10-15ml per kg per meal can be given via continuous rate infusion the animal clinic working hours
134
State and explain some of the common problems with feeding tubes (5)
blockages dislodging of the tube trauma to the site of tube or the tube itself infection over-granulation
135
What is Over-granulation?
where the tissues start to heal over the tube before you want it to
136
What are the main causes for the problems associated with feeding tubes? (4)
not flushing the tube coughing, sneezing, vomiting chewing, biting, pawing at the tube poor care of the surgical site
137
Feeding the critical patient: - What should you do before each tube feed? - How much of the RER should you give on day 1? - What about on day 2? - What about on day 3?
offer the patient food 1/3 2/3 entire RER
138
Managing the critical patient: - What records should you keep? (5)
the weight of the patient each morning, afternoon and evening the quantity of food and water given a note of how well the feed was tolerated a note when the dressings and stomas need changing or cleaning a clear feeding plan
139
When feeding through a feeding tube, what temperature should the food and water be given at? - Why is it best to not use a microwave? - how best do you get the food to this ideal temperature?
body temperature as it can lead to heat spots take the food out well in advance to warm it to room temperature
