Preoperative Evaluation and Anesthesia Documentation Flashcards
purpose of preop evaluation
evaluate current physical status and optimize the patient for surgery
goals of preop evaluation
obtain medical and surgical hx
evaluate the pt and determine the need for preop studies or consults
formulate and deliver safe anesthetic plan
minimize periop morbid/mortality
optimize pt safety and satisfaction
prevent surgical cancellations and delays
which standards relate to the preop eval and documentation?
standard 2: preanesthesia patient assessment and evaluation
standard 4: informed consent for anesthesia care
standard 5: documentation
what does standard 2 entail?
perform and document or verify documentation of a preanesthesia eval of the pt’s general health, allergies, medication hx, preexisting conditions, anesthesia hx, and any relevant diagnostic tests. Perform and document or verify documentation of an anesthesia focused physical assessment to form the anesthesia plan of care
anesthesia care documentation
- name and facility ID number of pt
- name all anesthesia professionals involved in the pt’s care
- immediate preanesthesia assessment and evaluation
- anesthesia safety checks
- monitoring of the patient
- airway management techniques
- name, dosage, route, and time of admin of drugs and anesthetics
- techniques used and pt positioning
- name and amounts of IV fluids
- IV/intravascular lines inserted
- any complications, adverse reactions, or problems during anesthesia
- status of pt at the conclusion of anesthesia
- documentation in a timely and legible manner
What would be an acceptable modification of the AANA standards?
emergency cases
before the delivery of anesthesia care, the provider is responsible for
- reviewing the available medical record
- interviewing and performing a focused exam of the patient to discuss the medical hx and assess the pt’s physical condition that might affect decisions
- ordering and reviewing pertinent available tests and consultations as necessary
- ordering appropriate preop meds
- ensuring that consent has been obtained
- documenting in the chart that the above has been performed
the record should include documentation of
- patient interview assessing pt and procedure, anticipated dispo, medical, surgical, and anesthetic hx, current meds, allergies, NPO status, advance directives
- appropriate physical exam
- objective diagnostic data
- medical consults
- ASA
- the anesthetic plan
- informed consent
- appropriate premed and prophylactic antibiotic admin
essential components of the anesthesia interview
BMI, allergies, NPO instructions, meds, previous anesthetics/complications, family hx of MH, possibility of pregnancy, systems review, baseline level of cognition, airway assessment
BMI - other name, equation
Quetelet Index
BMI (kg/m^2) = [weight (pounds) / height (inches)^2] x 703
Normal range for BMI
18.5 - 24.99
Overweight BMI
> 25
Obese BMI
> 30
Obese class I BMI
30-34.99
Obese class 2 BMI
35-39.99
Obese class 3 BMI
> 40
preobese BMI
25-29.99
underweight BMI
<18.5
ask allergies to:
drugs, dyes, contrast, latex, foods, and tape
things to consider when asking about allergies
exaggerated immune response or hypersensitivity?
allergen and the type of reaction
side effects
throat or tongue swelling, difficulty breathing?
things to consider/ask when asking about anesthetic and surgical histories:
previous anesthesia/surgeries: type of surgery, type of anesthesia, date, complications (PONV, MH, difficult intubation, awareness/recall, prolonged wakeup, unplanned postop intubation)
did you receive a letter from anesthesia after your surgery?
prolonged sore throat after surgery?
significant weight gain since last surgery?
things to ask about history of MH
family hx of MH?
did they survive?
have you had genetic testing?
purpose of NPO guidelines?
reduce the risk of aspiration
aspiration
accidental inhalation of gastric contents into the lungs = chemical burn of the tracheobronchial tree and pulmonary parenchyma = intense parenchymal inflammatory reaction
patients typically with longer stomach emptying times
diabetics, recent injuries, obesity, abdominal complaints, acid reflux, pregnant
what do we consider emergency/trauma cases in terms of NPO status?
full stomach
increased abdominal pressure/ascites puts patients at risk for
aspiration
clear liquids recommended fast
2 hours
examples of clear liquids
water, black coffee, tea, pulp free juice, carbonated beverages
breast milk recommended fast
4 hours
formula or cows milk, tea, coffee with milk/cream, full liquids, light meal, gum, sweets recommended fast
6 hours
full meal, fried or fatty food recommended fast
8 hours
What is Selleck’s Manuever
straight downward force on the cricoid cartilage and cervical spine
attempts to protect against aspiration
compresses the esophageal lumen between the cricoid cartilage and cervical spine
how much force is used with the selleck’s manuever
30-40 Newtons = 3-4 kg = 6.6-8.8 pounds
baseline physical exam includes
heart/breath sounds, breathing pattern, bruising/scarring, peripheral pulses/edema, vital signs, mental status, sensory/motor deficits, airway
airway assessment
identify hard and soft palate, tonsil, faucial pillars, and uvula
determine Mallampati class (I-IV)
have patient look at you at chin level, open wide, stick tongue out
Mallampati Class I
faucial pillars, hard and soft palate, and uvula
Mallampati Class II
faucial pillars, soft palate, and partial uvula
Mallampati Class III
soft palate and base of uvula
