Dex, Des, or Done?
I'm an inhaled agent with low solubility, a pungent odor, and may cause tachycardia when increased too quickly.
What is desflurane?
MAP is most commonly calculated using this formula.
What is (SBP + 2×DBP)/3?
This spinal level corresponds to the umbilicus and is the goal level for a hernia repair block
What is T10?
This IV induction agent is associated with pain on injection, likely due to its lipid formulation.
What is propofol?
An increase in this variable will lower PaCO₂ during controlled ventilation.
What is minute ventilation (or alveolar ventilation)?
I’m an α2-agonist that causes bradycardia, hypotension, and sedation without respiratory depression.
What is dexmedetomidine?
This is the most common cause of intraoperative hypotension immediately after induction.
What is vasodilation (from anesthetic agents)?
Hypotension after spinal anesthesia is primarily caused by blockade of this autonomic system.
What is the sympathetic nervous system?
This opioid has ultra-fast onset and offset due to its ester metabolism by plasma esterases.
What is remifentanil?
A PaO₂ of 55 mmHg on room air suggests this category of hypoxemia.
What is moderate hypoxemia?
I’m an oral acetylcholinesterase inhibitor used in Alzheimer's disease and could prolong succinylcholine block.
What is donepezil?
An increase in afterload will have what effect on stroke volume (all else equal)?
What is decrease it?
This condition occurs if spinal anesthesia ascends too high, potentially affecting phrenic nerve function.
What is high spinal (or total spinal)?
The context-sensitive half-time of this hypnotic agent remains short, even after long infusions.
What is propofol?
This acid-base disturbance presents with low pH, high PaCO₂, and normal HCO₃⁻ acutely.
What is acute respiratory acidosis?
My MAC is about 6.0 and I'm often avoided in patients with reactive airways
What is desflurane?
This hemodynamic parameter is calculated as (MAP – CVP) ÷ CO
What is systemic vascular resistance (SVR)?
The duration of spinal anesthesia with bupivacaine can be prolonged by adding this intrathecal adjunct.
What is epinephrine (or a vasoconstrictor)?
Succinylcholine’s rapid onset and offset make it ideal for RSI—but this genetic condition could prolong its duration.
What is pseudocholinesterase deficiency?
This phenomenon occurs when oxygen administration displaces CO₂ from hemoglobin, decreasing total CO₂ content.
What is the Haldane effect?
I reduce anesthetic requirements and provide cooperative sedation, often used in awake fiberoptic intubations.
What is dexmedetomidine?
These are the two primary determinants of coronary perfusion pressure.
What are aortic diastolic pressure and LVEDP?
Epidural space depth from skin is usually this range in cm in adults, depending on body habitus.
What is 4–6 cm?
This drug is a non-depolarizing NMBD but has one of the fastest onsets of its class due to low potency and high dose.
What is rocuronium?
This is the expected compensatory rise in HCO₃⁻ for a chronic respiratory acidosis.
What is 4 mEq/L increase in HCO₃⁻ per 10 mmHg ↑ PaCO₂?
