In a scenario involving a rapid sequence intubation with hemodynamic instability, which adjustment would most likely reduce the risk of further instability?

• A. Reduce the dose of the paralytic agent
• B. Increase the dose of the induction agent
• C. administer a large fluid bolus before induction
• D. administer push-dose vasopressor after induction

Answer: (A)

Minimizing the cardiovascular perturbations that can occur during airway management is essential when the patient is hemodynamically unstable. In rapid sequence intubation, the combination of induction and paralysis can cause a drop in blood pressure and other instability. Using a smaller dose of the paralytic agent helps limit the depth and abruptness of neuromuscular blockade, which in turn reduces the likelihood of sudden hemodynamic swings associated with a large or rapid paralytic effect. This approach aims to achieve quick, safe intubation while avoiding additional cardiovascular stress.

Increasing the induction dose would more likely worsen hypotension in an unstable patient. Administering a large fluid bolus before induction risks fluid overload and pulmonary edema. Relying on a vasopressor after induction addresses BP after instability has occurred but does not prevent the instability during the induction–paralysis sequence.
