Letter to the editor: “Combination of norepinephrine with phenylephrine versus norepinephrine with vasopressin in critically ill patients with septic shock: A retrospective study”

[...]the volume or type of fluid supplemented changed over different time periods [2]. [...]the indication, initiation timing, and facilities of renal replacement therapy might change over time. Furosemide may be considered after restoration of adequate blood pressure and tissue perfusion. [...]a maximum dose of 0.04 units/min of vasopressin was used in this study, and the SSC guidelines recommend a lower fixed dose of 0.03 units/min vasopressin [5].
