support of the anaesthetic patient

Question 1

fluid therapy

Answer 1

intraoperative fluids help maintain bp and ensure adequate tissue perfusion
indicated for patients under anaesthetic for over 30 mins

Question 2

fluids for dehydration

Answer 2

pre op dehydration should be corrected 12-24 hours prior
fluids should be warmed to body temp

Question 3

drug therapy

Answer 3

may be indicated if fluid therapy on its own does not maintain bp and tissue perfusion

Question 4

positive inotropes

Answer 4

increase cardiac contractility
dopamine

Question 5

anticholinergics

Answer 5

increase HR
atropine

Question 6

electrocardiography

Answer 6

ECG
visual representation of cardiac electrical activity

Question 7

when connecting ECG

Answer 7

ensure you have
conduct agent
quiet area
reduced interference

Question 8

intermittent positive pressure vetilation

Answer 8

IPPV
manually ventilating the intubated patient with the O2 bag on the anaesthetic circuit
hypoventilating, apnoeic

Question 9

IPPV technique

Answer 9

watching rise and fall of the chest as the bag is being squeezed and released

Question 10

ventilators

Answer 10

mechanically breaths for an animal which is unable to spontaneously breath
expandable bag is enclosed in an airtight bottle

Question 11

weaning off ventilator

Answer 11

done slowly
assess level of patient spontaneous response
gradually decline bpm - CO2 build up to stimulate respiration
monitor, RR, MM, CRT, HR, ETCO2

Question 12

reduced venous return

Answer 12

IPPV complication
ippv creates positive pressure, putting pressure on vessels causing partial collapse and impended flow

Question 13

Pneumothorax

Answer 13

IPPV complication
lung collapse due to over inflation

Question 14

re expansion pulmonary oedema

Answer 14

IPPV complication
trauma caused by rapid inflation to damaged lung, causing fluid build up

Question 15

respiratory alkalosis

Answer 15

IPPV complication

Question 16

O2 therapy

Answer 16

pre and post op
flow by, mask, nasal prongs, hood, cage

Question 16

intraoperative hypothermia

Answer 16

anaesthetic agents increase heat loss due to CNS depression and alcohol based prep, cold ivf

Question 17

intraop hypothermia

Answer 17

increases anaesthetic depth, delays recovery, cardiovascular depression
minimised by, minimal anaesthetic time, warm ivf, heating aids

Question 18

musculoskeletal and peripheral nervous system support

Answer 18

myopathy and neuropathy
caused by inpropper support of anaesthetised patient
poor positioning and padding, hypotension, excessive force
