Which monitoring approach is emphasized for septic shock management during anesthesia?

• A. Intermittent noninvasive blood pressure measurements only.
• B. Continuous hemodynamic monitoring, including arterial line and central venous access.
• C. No monitoring unless hypotension occurs.
• D. Telemetry only.

Answer: (B)

In septic shock during anesthesia, the patient’s hemodynamics are highly unstable and can change rapidly with shifts in preload, afterload, and cardiac function. Real-time data are essential to guide fluids, vasopressors, and inotropes to maintain adequate tissue perfusion.

An arterial line gives beat-to-beat blood pressure and allows frequent arterial blood sampling, which is crucial for accurately targeting mean arterial pressure and for monitoring oxygenation and acid-base status as therapy is titrated. Central venous access provides rapid administration of vasoactive drugs and fluids, and it allows monitoring of central venous pressures to gauge preload and, when available, central venous oxygen saturation to assess the balance between oxygen delivery and consumption. This invasive setup supports dynamic, goal-directed management better than intermittent measurements or noninvasive telemetry in a high-risk, rapidly changing situation.

Intermittent noninvasive monitoring could miss critical shifts and delaying treatment until hypotension is evident is unsafe in septic shock. Telemetry alone also lacks the necessary hemodynamic data to guide fluid and vasoactive therapy.
