Sepsis-associated Hypotension, Septic Shock
Conditions
Brief summary
In hypotensive septic patients with controlled source, an hemodynamic management protocol including hypertonic saline (HS)and terlipressin improves MOD (Multiple Organ Dysfunction) Score by at least 3 points compared to the use of physiologic saline and norepinephrine. The appropriate design for this trial would be factorial. For the time being, will consider de intervention as a whole unit for this pilot study. In the future an appropriately sized factorial multicentric study shall be necessary. Other goals of the pilot study: 1. HS restores preload parameters adequately 2. HS associated with terlipressin normalizes blood pressure in septic shock 3. HS associated with terlipressin maintains plasma sodium levels 130-155mEq/L 4. There is an inverse relationship between plasma sodium and procalcitonin levels 5. HS increases plasma levels of vasopressin (AVP) 6. HS rises levels of cortisol but not of adrenocorticotropic hormone (ACTH)
Interventions
DRUGHypertonic Saline and Terlipressin
Hypertonic saline 3% 7mL/Kg (with a maximum 500 mL)triggered by either Systolic Volume Variation or Pulse Pressure Variation more than 10%; Terlipressin infusion (dilution 1mg in 100mL) triggered by MAP below 70 mmHg for a goal MAP above 70 mmHg
DRUGNormal saline and norepinephrine
Normal saline IV bolus 7mL/kg (with a maximum 500 mL)triggered by either Systolic Volume Variation or Pulse Pressure Variation above 10%; Norepinephrine drip (80 micrograms/mL) to keep MAP at least 70 mmHg

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| MOD (Multiple Organ Dysfunction) Score | daily, as long as the patient stays in the ICU |
Secondary
| Measure | Time frame |
|---|---|
| Hypertonic Saline associated with terlipressin maintains plasma sodium levels 130-155mEq/L | As long as Hypertonic saline plus terlipressin are in use and one week later |
| There is an inverse relationship between plasma sodium and plasma procalcitonin levels measured by a negative Pearson coefficient | As long as the patient stays in the ICU |
| Hypertonic Saline restores IV fluid response parameters (Pulse Pressure Variation or Systolic Volume Variation) adequately | First 48 hours |
| Hypertonic Saline boluses increases plasma levels of vasopressin (AVP) | First week in ICU |
| Hypertonic Saline use rises levels of cortisol but not of adrenocorticotropic hormone (ACTH) | First week in ICU |
| Hypertonic Saline associated with terlipressin normalizes blood pressure in septic shock | First 48 hours |
