Retrospective study to examine the effects of chronic antihypertensive medications on vasopressor dosing in septic shock
This will be a retrospective four-cohort study. The four cohorts will be septic shock patients that were: 1) not on either a chronic β-blocker or chronic angiotensin-converting-enzyme inhibitor (ACE-Inhibitor), 2) on chronic β-blocker, 3) on ACE-Inhibitor, and 4) on both chronic β-blocker and ACE-inhibitor

Total Vasopressor Dose
The primary objective is to determine the effect of chronic β-blocker or ACE-inhibitor on vasopressor dosing in the first 48 hours of septic shock. Vasopressor types and cumulative doses including: norepinephrine, epinephrine, phenylephrine, dopamine, and vasopressin. Epinephrine, phenylephrine, and dopamine will be converted to norepinephrine equivalents in concordance with other literature: 100 mcg dopamine equivalent to 1 mcg norepinephrine, 1 mcg epinephrine equivalent to 1 mcg norepinephrine, and 2.2 mcg phenylephrine equivalent to 1 mcg norepinephrine
Time frame: 48 hours
30 mL/kg Fluid Within 6h
Number of Participants with 30 mL/kg Fluid Within 6 Hours
Time frame: 48 hours
Inotrope Use
Cumulative inotrope use at different time points (total mg). Example inotropes include dobutamine and milrinone
Time frame: 6, 12, 24, 48 hours
Hydrocortisone Use
Cumulative hydrocortisone (mg) use at different time points
Time frame: 6, 12, 24, 48 hours
Cumulative Vasopressor Dose for Patients Receiving Other Antihypertensives
To determine cumulative vasopressor dose at various time points of patients on chronic calcium channel blocker or other antihypertensives (i.e., hydralazine, clonidine, angiotensin-receptor-blocker (ARB), etc). Vasopressor types and cumulative doses including: norepinephrine, epinephrine, phenylephrine, dopamine, and vasopressin. Epinephrine, phenylephrine, and dopamine will be converted to norepinephrine equivalents in concordance with other literature: 100 mcg dopamine equivalent to 1 mcg norepinephrine, 1 mcg epinephrine equivalent to 1 mcg norepinephrine, and 2.2 mcg phenylephrine equivalent to 1 mcg norepinephrine
Time frame: 6, 12, 24, 48 hours

6-hour Vasopressor Dose
Vasopressor types and cumulative doses including: norepinephrine, epinephrine, phenylephrine, dopamine, and vasopressin. Epinephrine, phenylephrine, and dopamine will be converted to norepinephrine equivalents in concordance with other literature: 100 mcg dopamine equivalent to 1 mcg norepinephrine, 1 mcg epinephrine equivalent to 1 mcg norepinephrine, and 2.2 mcg phenylephrine equivalent to 1 mcg norepinephrine
Time frame: 6 hours
12-hour Vasopressor Dose
Vasopressor types and cumulative doses including: norepinephrine, epinephrine, phenylephrine, dopamine, and vasopressin.

Time frame: 12 hours
24-hour Vasopressor Dose
