Correction: An updated “norepinephrine equivalent” score in intensive care as a marker of shock severity

Abstract

Correction: Critical Care (2023) 27:29 https://doi.org/10.1186/s13054-023-04322-y

Following publication of the original article [1], the authors would like to correct the correction rate for metaraminol which is 1/8 under the heading Proposed updated norepinephrine equivalent score, Figure 1 and Table 1.

The sentences currently reads:

A randomized trial compared metaraminol and norepinephrine in septic shock [38]. Based on the findings of this trial suggesting 2.5 μg/kg/min of metaraminol corresponded to 0.3 μg/kg/min of norepinephrine, we defined a correction factor of 8 to metaraminol dose in μg/kg/min.

The sentences should read:

A randomized trial compared metaraminol and norepinephrine in septic shock [38]. Based on the findings of this trial suggesting 2.5 μg/kg/min of metaraminol corresponded to 0.3 μg/kg/min of norepinephrine, we defined a correction factor of 1/8 to metaraminol dose in μg/kg/min.

The incorrect Figure 1:

The given sentences under the heading Proposed updated norepinephrine equivalent score, Figure 1 and Table 1 have been updated in this correction article and the original article [1] has been corrected.
