ASA Class I
No organic, physiologic, biochemical, or psychiatric disturbances (healthy patient)
ASA Class II
Mild to moderate systemic disturbance. (Heart disease that SLIGHTLY LIMITS physical activity, essential HTN, diabetes, chronic bronchitis, anemia, obesity, age etremes)
ASA Class III
Severe systemic disease that limits acitivity. (Limits activity, poorly controlled essential HTN, diabetes mellitus WITH VASCULAR COMPLICATIONS, angina pectoris, history of previous MI)
ASA Class IV
Severe systemic disease THAT IS CONSTANTLY LIFE THREATENING. (CHF, pers angina pectoris, advance pulm, renal, or hepatic dysfunction)
ASA Class V
Moribound pt, undergoing surgery as a RESUSCITATIVE EFFORT, despite a minimal chance for survival. (uncontrolled hem from ruptured abdominal artery aneurysm, PE, head injury w increased ICP)
ASA Class VI
Declared brain dead pt whose organs are being removed for donor purposes
ASA Class E
Emergency surgery is required (otherwise healthy 30 yo female who needs Dand C for mod persistent hemorrhage

who found the first anesthesia school and when
Agatha Hodgins 1915
where was the first organized educational program

Thyro-mental distance
measure from upper edge of thyroid cartilage to chin with the head fully extended.
short = an anterior larynx
>7cm is usally=easy intubation
<6cm=difficult airway
first step of difficult airway algorithm
assess the likelihood and clinical impact of basic managment problems:
A. Difficult ventilation
B. Difficult Intubation
C. Difficult with Pt Cooperation or Consent
D. Difficult Tracheostomy
Second step of Difficult airway algorithm
- Actively pursue opportunities to deliver supplemental oxygen throughout the process of difficult airway management
Difficult airway algorithm 3. A
awake intubation vs intubation attempts after induction of general anesthesia
Difficult airway algorithm 3. B
Non-invasive technique for initial approach of intubation vs. invasive technique for initial approach to intubation
Difficult airway algorithm 3. C
preservation of spontaneous ventilation vs ablation of spontaneous ventilation.
