What is the motto of the anesthetist?
"The anesthetist's job is either too boring or too exciting"
What are some causes for anesthetic problems?
- human error
- equipment failure
- anesthetic agents
- patient variation factors
Every anesthetic episode has the potential to _____ the patient.
What could cause human error?
- slightly experienced
- incomplete preliminaries
- incorrect administration of drugs
- preoccupied or in a hurry
What does it mean to be slightly experienced?
overconfident beyond their ability
What could a tech fail to complete in the preliminaries?
- obtain an adequate history - lack of details
- perform an adequate PE - miss dyspnea, anemia, dehydration
- lack of access to owner (owner drops off pet)
- owner not questioned properly
- information obtained by not recorded or passed on
How can someone be unfamiliar with protocol or equipment?
- clueless about drugs, dosages, anesthesia machine
- untrained, unlicensed
- performing duties beyond training and ability
How can a tech administer the drugs incorrectly?
- wrong patient weight
- wrong math
- wrong drug
- wrong concentration
- wrong route
- wrong patient
How can a tech be inattentive?
distracted, bored, tired
When should procedures be scheduled in order to cut down on fatigue of the staff?
early in the day when everyone is fresh
Equipment failure is really what? Why?
- human failure
- bc equipment was not checked before use or not maintained properly
What parts of the equipment could fail?
- CO2 absorber
- O2 tank
- endotracheal tube
- pop-off valve
What problems could we have with the CO2 absorber?
How can a CO2 absorber that is not working correctly affect the patient?
- respiratory acidosis
- increased RR, HR
- CNS damage
What could go wrong with the O2 tank and what can we do to fix this?
- could be empty
- check before procedure
What needs to be on in order for the patient to breathe?
O2 tank AND flowmeter
What do we need to check during the procedure for the O2 tank?
check flowmeter, O2 tank, and reservoir bag every 5 minutes
How do we check to make sure the anesthesia is assembled correctly?
trace path of O2 flow
What are some problems we could have iwht the endotracheal tube?
- cuff not inflated
- too small
- in esophagus
What problems could we have with the vaporizer?
- wrong anesthetic liquid
- inaccurate, stick dial
What problems could we have with the pop-off valve?
- left closed after bagging
- results in high pressure in breathing circuit
High pressure in breathing circuit could result in...
- harder to breathe
- pressure on great vessels which impairs blood flow to heart
- possible ruptured alveoli
- can be fatal
How do we prevent too much pressure in the breathing circuit?
keep bag no more than 2/3 full
