---|---|---|
Which MAP targets to stabilize the macrocirculation? | MAP ≥ 65 mmHg | What is the best timing for MAP intervention in sepsis? and until when? Could “permissive hypotension” be considered as in the case of trauma? for which reason(s) and target(s)? |
How much fluid resuscitation and when? | From “time of presentation” or “time zero,” 30 mL/kg at least within 1 h | Should we prioritize fixed minimum fluid resuscitation or dynamic personalized reassessment of circulation status? |
Which fluid(s)? | Crystalloids | Beyond balanced versus unbalanced crystalloid fluid selection, should we prefer acetate- or lactate-buffered solutions? |
How long? | After the initial 1-h interventions, further fluid administration needs patients’ assessment for responsiveness | What “gauge for a filled tank”? |
Which vasoactive (± inotropic) drug(s)? | NE is recommended as a 1st choice vasopressor. AVP or E can be added to help reaching the target (i.e., MAP) and spare NE | Within a “hour-1 bundle” strategy, should we trade-off less fluids and more vasoactive drugs to vice versa? |
When? | Dobutamine only if target not reached after adequate fluid loading and use of vasoactive drugs | Are vasopressor combinations able to reach high MAP levels without detrimental cardiac side effects? |
As early as during the initial fluid resuscitation period, to achieve the target MAP ≥ 65 mmHg ASAP | With NE as the currently recommended first-line vasopressor is “decatecholaminization” feasible and safe? |
