1. Preoxygenation and safe apnea time
A 56-year-old obese man with obstructive sleep apnea is scheduled for
elective laparoscopic cholecystectomy under general anesthesia. After
induction with propofol and rocuronium, direct laryngoscopy is
unexpectedly difficult. Before intubation, his oxygen saturation was
100% after several minutes of preoxygenation. Which physiologic factor
most directly explains why an obese patient may desaturate more rapidly
during apnea despite adequate preoxygenation?
A. Increased functional residual capacity
B. Decreased oxygen consumption
C. Decreased functional residual capacity combined with increased
oxygen consumption
D. Increased pulmonary compliance
E. Increased alveolar dead space alone
Answer: C. Decreased functional residual capacity combined with
increased oxygen consumption
Rationale: Obesity decreases functional residual capacity, particularly
when the patient is supine, reducing the pulmonary oxygen reservoir
available during apnea. At the same time, oxygen consumption is
increased because of greater metabolic demand. These factors
1
,combine to accelerate arterial desaturation. Preoxygenation increases
the fraction of oxygen within the functional residual capacity, but it
cannot completely eliminate the underlying limitation created by
reduced FRC. Positioning the patient in a head-elevated or ramped
position can improve FRC and laryngoscopic conditions.
2. Propofol-induced hypotension
A healthy 35-year-old woman receives propofol for induction of general
anesthesia. Shortly after administration, her blood pressure decreases
from 125/75 mmHg to 75/40 mmHg, while heart rate remains 68
beats/min. Which mechanism best explains this response?
A. Increased systemic vascular resistance
B. Increased sympathetic nervous system activity
C. Arterial and venous vasodilation with attenuation of sympathetic tone
D. Severe histamine release in all patients
E. Direct myocardial stimulation
Answer: C. Arterial and venous vasodilation with attenuation of
sympathetic tone
Rationale: Propofol commonly causes hypotension through decreased
systemic vascular resistance, venodilation, reduced preload, and
suppression of sympathetic vasoconstrictor responses. Myocardial
depression can also contribute, particularly in patients with limited
cardiac reserve. The absence of compensatory tachycardia is
characteristic because propofol can blunt the normal baroreceptor-
mediated sympathetic response.
3. Malignant hyperthermia
A 22-year-old man develops rapidly increasing end-tidal CO₂,
tachycardia, generalized muscle rigidity, hyperkalemia, and metabolic
2
,and respiratory acidosis shortly after induction with sevoflurane and
succinylcholine. His temperature is initially normal. What is the most
appropriate immediate treatment?
A. Administer IV acetaminophen
B. Administer dantrolene and immediately discontinue triggering
anesthetics
C. Administer calcium gluconate only
D. Increase the concentration of volatile anesthetic
E. Administer succinylcholine to terminate muscle rigidity
Answer: B. Administer dantrolene and immediately discontinue
triggering anesthetics
Rationale: The presentation is classic for malignant hyperthermia, a
hypermetabolic skeletal-muscle disorder involving abnormal calcium
release from the sarcoplasmic reticulum. Early manifestations often
include unexplained rising ETCO₂, tachycardia, rigidity, acidosis, and
hyperkalemia; hyperthermia may occur later. Management requires
immediate discontinuation of volatile anesthetics and succinylcholine,
administration of IV dantrolene, hyperventilation with 100% oxygen,
aggressive treatment of hyperkalemia and acidosis, active cooling
when indicated, and appropriate critical-care monitoring.
4. Local anesthetic systemic toxicity
A patient undergoing an ultrasound-guided brachial plexus block
suddenly develops circumoral numbness, tinnitus, agitation, followed by
generalized tonic-clonic seizure and cardiovascular collapse. Which
treatment is most appropriate?
A. IV lidocaine infusion
B. IV lipid emulsion therapy
C. IV calcium chloride as sole treatment
3
, D. Immediate administration of a volatile anesthetic
E. Large-dose beta blocker
Answer: B. IV lipid emulsion therapy
Rationale: This is local anesthetic systemic toxicity (LAST), usually
caused by excessive plasma concentrations of a local anesthetic from
inadvertent intravascular injection, excessive dosing, or rapid systemic
absorption. Management includes stopping local anesthetic
administration, securing the airway and oxygenation, treating seizures
appropriately, and administering intravenous lipid emulsion for
significant toxicity. Cardiovascular resuscitation should follow
specialized LAST principles because some conventional resuscitation
drugs and doses may worsen toxicity.
5. Spinal anesthesia hypotension
A 72-year-old patient receives spinal anesthesia for hip surgery. Shortly
afterward, blood pressure decreases substantially and heart rate falls to
48 beats/min. What is the primary mechanism responsible?
A. Increased systemic vascular resistance
B. Sympathetic blockade causing arterial and venous dilation
C. Direct myocardial toxicity from bupivacaine
D. Increased circulating catecholamines
E. Pulmonary vasoconstriction
Answer: B. Sympathetic blockade causing arterial and venous
dilation
Rationale: Spinal anesthesia blocks sympathetic efferent pathways,
producing vasodilation and venous pooling below the level of the
block. Reduced venous return decreases preload and cardiac output. If
the block affects cardiac accelerator fibers or produces profound
reduction in venous return, bradycardia may occur. Treatment
