Session 11 Flashcards
normal induction sequence (3)
pre-op
induction
extubation
8 phases of induction
anxiolysis
pt to room/table
monitors attached
pre-oxygenated
anesthetic time out
induction
airway management
prepare for incision
anxiolysis
fear
anxiolysis medications
versed (1-2mg up to 4mg)
fentanyl (25-50mcg)
versed should not be given to
elderly pts
progresses dementia/alzheimers
move to operating table
do not let IV get pulled out
move to operating table steps
- untie knots
- lock gurney and table
- pt move over
- ensure pt doesnt move too far
- secure pt w/belt
monitors
1) NIBP (3-5 min inter)
2) EKG (5 lead std)
3) pulse ox (iv arm ring)
4) temp
5) capnography (tight seal on mask, have pt exhale forcefully)
6) O2 analyzer (w/cap)
7) PNS (post induction)
Pre-Oxygenation
flush out nitrogen in alveoli
maximally saturate the hemoglobin/blood w/O2
denitrogenation
Situations where hypoxia can quickly occur
- supine obese pts
- sedation (drug induced)
- paralysis
PreOx Method: Tidal Volume Ventilation
*most effective
vol of air inhaled and exhaled w/normal breathing
3+ mins w/good seal
PreOx Method parameters
FiO2 100%
O2 10-12L/min
open APL valve
facemask seal
PreOx Method: Vital Capacity Ventilation
max vol of gas that can be exhaled following maximal inspiration
4 breaths over 30 sec
or
8 breaths over 60 sec
PreOx issues
claustrophobic pts
blow by technique w/higher %O2
or
have pt hold mask
How do we confirm pre-Ox successful?
EtO2 > 85%
SpO2 (not perfect measurement)
Anesthesia Time Out Steps (8)
- Name/Dob/Surgery
- allergies
- pre-op meds/proceds
- Plan
- general vs MAC
- LMA vs ETT
- suction, O2, monitors, vaporizers
- Additional procedures
- sequential compression devices
- misc items
induction overal steps (14)
- Pt head tilt/chin lift
- give meds
- confirm asleep verbal
- eyelid reflex test
- test ventilate
- tape eyes
- paralytic
- DL or LMA
- Ventilator
- Volatile agent
- reduce fresh gas flw
- tem p probe/PNS
- Position accordingly
- warming device
how to speed up induction speed
increase %
increase FGF
increase RR or TV (increase minute vent)
additional procedures to perform post inductions
PIV
A Line
Central Line
Foley
Block
sequential compression device prevent
DVT
common induction medications
fentanyl
lidocaine
propofol
rocuronium(post reflex check)
fentanyl onset
3-7 mins
fentanyl alleviates
alleviates sympathetic response to intubation
lidocaine induction effect
helps attentuate sting of propofol
lg doses reduce airway reflexes
lidocaine mechanism
Na+ antagonist
blocks nerve impulses
propofol effect
stings
high-lipid solubility
== fast speed
