Eligibility Criteria:
Inclusion Criteria:
* Adult patients ≥18 years-old with persistent vasodilatory shock despite moderate-dose norepinephrine monotherapy, defined as those who require ≥0.1 mcg/kg/min for at least 30 minutes to maintain a MAP between 65-70 mmHg.
* Patients are required to have central venous and arterial catheters present, and they are expected to remain in place for at least the initial 72 hours of study.
* Patients are required to have an indwelling urinary catheter present, and it is expected to remain in place for at least the 72 hours of study.
* Patients must have received 20-30 mL/kg of crystalloid over the previous 24-hour period, as clinically appropriate, and no longer be fluid responsive as per UNMH protocol. By UNMH protocol, lack of fluid responsiveness is considered a failure to increase stroke volume, stroke volume index, cardiac output, or cardiac index (typically measured by non-calibrated pulse contour analysis using a FloTrac device) by at least 10% after a 500-mL crystalloid bolus or a passive leg raise. Patients for whom the treating physicians feel that 20 mL/kg of crystalloid may be clinically inappropriate can qualify for the study if the reason for withholding further IV fluids is documented.
* Patient or (in patients unable to consent) legal authorized representative (LAR) is willing and able to provide written informed consent and comply with all protocol requirements.
* Approval from the attending physician and clinical pharmacist conducting the study.
Exclusion Criteria:
* Patients who are \< 18 years of age.
* Patients diagnosed with acute occlusive coronary syndrome requiring intervention and/or cardiogenic shock.
* Patients with or suspected to have abdominal aortic aneurysm or aortic dissection.
* Acute stroke.
* Patients with acute mesenteric ischemia or those with a history of mesenteric ischemia.
* Patients with known Raynaud's phenomenon, systemic sclerosis, or vasospastic disease.
* Patients on venoarterial extracorporeal membrane oxygenation (VA-ECMO).
* Patients with liver failure with a Model for End-Stage Liver Disease (MELD) score of =/\>30.
* Patients with burns covering \>20% of total body surface area.
* Patients with a history of asthma or chronic obstructive pulmonary disease (COPD) with active acute bronchospasm or (if not mechanically ventilated) with an acute exacerbation of their asthma/COPD requiring the use of inhaled bronchodilators.
* Patients requiring more than 500 mg daily of hydrocortisone or equivalent glucocorticoid medication as a standing dose.
* Patients with an absolute neutrophil count (ANC) of \< 1,000/mm3
* Patients with hemorrhagic shock OR active bleeding AND an anticipated need (within 48 hours of initiation of the study) for transfusion of \>4 units of packed red blood cells.
* Patients with active bleeding AND hemoglobin \< 7g/dL or any other condition that would contraindicate serial blood sampling.
* Untreated venous thromboembolism (VTE) or inability to tolerate pharmacologic VTE prophylaxis.
* Patients with a known allergy to mannitol.
* Patients with an expected survival of \<24 hours, SOFA score ≥ 16, or death deemed to be imminent or inevitable during the admission.
* Either the attending physician or patient and/or substitute decisionmaker are not committed to all active treatment, e.g., do-not-resuscitate (DNR) status.
* Patients who are known to be pregnant at the time of screening. All women ≤50 years-old will need a negative serum pregnancy test (serum quantitative beta-hCG) to enroll.
* Prisoner status
* Patients who are currently participating in another interventional clinical trial.
