anaesthetics 1 Flashcards
consequences of untreated pain
increased BP
increased HR
perip MI nausea
inability to cough and clear secretions - pneumonia
inability to move around - DVT, pressure sores
WHO pain ladder
paracetoma
NSAIDs
IM opioids
PCA patient controlled analgesia when can’t give oral opiods
complications of opiods
nausea and vom
over sedation
hypotension
resp depression - late in spinal/epidural
resp depression if RR <10
RR< 8
v drowsy
oxygen 6L/min
Oxygen 6L/min and stop opiod
nagoxon 1ml every min till RR >10
peripheral nerve blockade lasts how long
12-48 hours
epidural infusion anaesthesia hypotension management
elevation of legs oxygen fluids stat if severe IV ephedrine 3-6mg if low pressure metaraminol 0.5mg if fast HR
Epidural infusion cx
resp Depression itch - low dose nagoxon or chlorppheramine urinary retention - catheter motor block inadequate analgesia
post op care
hypotension resp - low oxygen GI n/v CNA - delayed return of consciousness urinary - post op oliguria
hypovalaemic shock
loss of blood
plasma - burns
fluid - GI obstruction
cariogenic shock
post MI - pump failure severe arrhthmias PE tension pneumothorax cardiac tamponade
vasogenic shock
anaphylaxis
severe sepsis
neurogenic shock
high spinal cord transaction
vaso vagal attack - fainting
brain death common causes
head injury
intracranial team
cerberal hypoxia
brain death diagnosis
two senior doctors
two sets of tests
brain death clinical signs
no pupillary response to light absent corneal reflexes absent caloric reflexes no motor responses in the distribution of cranial nerves no cough or gag reflex
