BCA Anesthesia Techniques & Patient Management 3

Question 1

Which hemodynamic change is most expected during the induction of neuraxial anesthesia at the T4 level in an otherwise healthy adult?

Accepted Answer

Hypotension and bradycardia

Answer

A T4 block abolishes cardioaccelerator fibers (T1-T4) and causes vasodilation, resulting in both bradycardia and hypotension.

Question 2

A patient develops masseter muscle rigidity immediately after succinylcholine administration. The most appropriate next management step is:

Accepted Answer

Switch to a TIVA technique and monitor temperature and end-tidal CO2

Answer

Masseter spasm after succinylcholine is a potential MH warning sign; discontinuing volatile agents and switching to TIVA while monitoring for MH is the safest immediate strategy.

Question 3

The Mallampati classification assesses which anatomical structures?

Accepted Answer

Visibility of the soft palate, uvula, and faucial pillars

Answer

The Mallampati score classifies airway difficulty based on the visibility of oropharyngeal structures: soft palate, uvula, and faucial pillars.

Question 4

During a laparoscopic procedure, sudden-onset hypotension and hypoxia occur after insufflation. Which diagnosis should be considered first?

Accepted Answer

CO2 gas embolism

Answer

CO2 gas embolism is a serious complication of laparoscopy that can cause sudden cardiovascular collapse and hypoxia due to obstruction of the right heart outflow.

Question 5

Which parameter best guides intraoperative fluid resuscitation in a goal-directed fluid therapy (GDT) protocol?

Accepted Answer

Stroke volume variation (SVV) or pulse pressure variation (PPV)

Answer

SVV and PPV are dynamic predictors of fluid responsiveness that outperform static measures like CVP in mechanically ventilated patients.
