    • Sodium Bicarbonate Administration Did Not Improve Hemodynamic Variables in Patients with Lactic Acidosis, But Did Not Worsen Tissue Oxygenation
  • French Multi-Center, Randomized BICAR-ICU Trial of Sodium Bicarbonate for ICU Patients with Severe Acidemia and Lactic Acidosis (Lancet, 2018) [MEDLINE]: n = 389 (from 26 French ICU’s)
    • Total Group
      • Sodium Bicarbonate Therapy for Severe Acidemia (pH ≤7.20, pCO2 ≤45 mm Hg, Serum Bicarbonate ≤20 mmol/L, SOFA ≥4. Arterial Lactate ≥2 mmol/L) Targeting a Serum pH >7.30 Did Not Significantly Decrease the 28-Day Mortality Rate (45%), as Compared to Control (54%)
      • Sodium Bicarbonate Did Not Decrease the Occurrence of at Least One Organ Failure at Day 7
    • Prespecified Acute Kidney Injury Network Group (with a Score of 2-3)
      • Sodium Bicarbonate Therapy Decreased the Mortality Rate (46%), as Compared to Control (63%)
      • Sodium Bicarbonate Decreased the Occurrence of at Least One Organ Failure at Day 7
    • Metabolic Alkalosis, Hypernatremia, and Hypocalcemia were Observed More Frequently in the Bicarbonate Group than in the Control Group
  • Pilot Randomized Double-Blind Clinical Trial of Sodium Bicarbonate Therapy for Metabolic Acidosis in the Intensive Care Unit (Crit Care Med, 2023) [MEDLINE]: n = 30
    • At Day 7, Patients in the Sodium Bicarbonate and Placebo Group Had a Median of 132.2 (85.6-139.1) and 97.1 (69.3-132.4) Hours Alive and Vasopressor-Free, Respectively (Median Difference 35.07; 95% CI: -9.14 to 79.28; p = 0.131)

Recommendations (Surviving Sepsis Campaign: International Guidelines for Management of Sepsis and Septic Shock 2021) (Crit Care Med, 2021) [MEDLINE]

  • For Adults with Septic Shock and Hypoperfusion-Induced Lactic Acidemia, Sodium Bicarbonate Therapy to Improve Hemodynamics or to Decrease Vasopressor Requirement is Not Recommended (Weak Recommendation, Low Quality of Evidence)
  • For Adults with Septic Shock and Severe Metabolic Acidemia (pH ≤ 7.2) and Acute Kidney Injury (AKIN Score 2-3), Sodium Bicarbonate Therapy is Recommended (Weak Recommendation, Low Quality of Evidence)

Blood Pressure Target

Clinical Efficacy

  • French SEPSISPAM Trial Examining Blood Pressure Targets in Septic Shock (NEJM, 2014) [MEDLINE]
    • MAP Target 80-95 mm Hg Had No 28-day Mortality (and 90-Day Mortality) Benefit, as Compared to MAP Target 65-70 mm Hg
    • Incidence of Newly Diagnosed Atrial Fibrillation was Higher in the MAP Target 80-95 mm Hg Group
    • In Patients with Chronic Hypertension, Those in the MAP Target 80-95 mm Hg Group Required Less Hemodialysis than Those in the MAP Target 65-70 mm Hg Group: however, no difference in mortality rate was observed
  • Systematic Review of Blood Pressure Target in Sepsis (Shock, 2015) [MEDLINE]
    • MAP Target of 80-85 mm Hg vs 65-70 mm Hg Had No Effect on 28-Day Mortality Rate
    • MAP Target of 80-85 mm Hg Increased the Risk of Atrial Fibrillation and a Lower Risk of Hemodialysis in Hypertensive Patients
    • Crossover Trials Suggested MAP Target of 80-85 mm Hg (Achieved by Increasing Vasopressor Doses) Increased Heart Rate and Cardiac Index Without an Effect on Serum Lactate
  • Critical Review of the Currently Recommended Blood Pressure Target of 65 mm Hg in Sepsis (Crit Care Med, 2015) [MEDLINE]
    • While MAP Target of >65 mm Hg is Appropriate in Most Patients, MAP Target of 75-85 mm Hg Decreases the Risk of Acute Kidney Injury in Patients with a History of Hypertension
  • Trial of Higher vs Lower Blood Pressure Targets for Vasopressor Therapy in Shock (Intensive Care Med, 2016) [MEDLINE]
    • In the Subgroup of Patients >75 y/o, Mortality was Decreased with MAP Target of 60–65 mmg Hg (13%) vs 75–80 mm Hg (60%)

Recommendations (Surviving Sepsis Campaign: International Guidelines for Management of Sepsis and Septic Shock 2021) (Crit Care Med, 2021) [MEDLINE]

  • For Adults with Septic Shock (on Vasopressors), Initial Mean Arterial Pressure (MAP) Target of ≥65 mm Hg is Recommended Over a Higher MAP Target (Strong Recommendation, Moderate Quality of Evidence)
    • However, Consideration of a Higher MAP Target (75-85 mm Hg) Might Be Appropriate in Patients with a History of Hypertension as This Intervention Might Decrease the Risk of Acute Kidney Injury Requiring Hemodialysis (NEJM, 2013) [MEDLINE]

Intravenous Fluid Resuscitation Strategy

History

  • Intravenous Fluid Resuscitation was First Described During the Cholera Outbreaks of the 1830’s (Emerg Med Clin North Am, 2020) [MEDLINE] (Open Access Emerg Med, 2022) [MEDLINE]
  • Intravenous Fluid Resuscitation Became Standard Practice During the Early 1900’s

Rationale

  • In the Setting of Sepsis, Increased Serum Lactate is a Marker of Impaired Microcirculatory Flow with Tissue Hypoxia (see Lactic Acidosis)
    • However, There are Scant Data that Tissue Hypoxia Occurs in Patients with Sepsis
    • In Addition, Increasing Oxygen Delivery in Patients with Sepsis Does Not Increase Oxygen Consumption
    • Increased Serum Lactate Levels are Associated with Worse Outcome (Crit Care Med, 2015) [MEDLINE]

Clinical Efficacy of Early Goal-Directed Therapy

  • Rivers Early Goal-Directed Therapy Trial (NEJM, 2001) [MEDLINE]
    • Goal-Directed Therapy Protocol was Triggered by Presence of SIRS Criteria + Systolic BP ≤90 mm Hg or Serum Lactate ≥4 mmol/L

    • Early Goal-Directed Therapy (Used for First 6 hrs of Emergency Department Care) Decreased 28-Day Mortality in Severe Sepsis and Septic Shock
    • As Compared to Standard Therapy, Early Goal-Directed Therapy Group (from 7-72 hrs) Resulted in Higher pH, Lower Base Deficit, Lower Lactate Concentration, and Significantly Higher Mean Central Venous Oxygen Saturation (ScvO2)
  • EMShockNet Trial (JAMA, 2010) [MEDLINE]
    • In Patients with Severe Sepsis/Septic Shock Treated to Normalize Central Venous Pressure/Mean Arterial Pressure, Additional Management to Normalize Lactate Clearance vs Management to Normalize Central Venous Oxygen Saturation Did Not Improve In-Hospital Mortality

    • With Early Diagnosis of Septic Shock, Early Goal-Directed Therapy Did Not Improve 90-Day All-Cause Mortality, as Compared to Usual Care
    • Early Goal-Directed Therapy Group Manifested Significantly Worse Organ-Failure Scores, More Days Receiving Advanced Cardiovascular Support, and Longer ICU Stays
    • Early Goal-Directed Therapy Increased Treatment Intensity (With Increased Use of Intravenous Fluids, Vasoactive Drugs, and Red Blood Cell Transfusions)
    • Early Goal-Directed Therapy Increased Costs (the Probability That it Was Cost-Effective Was <20%)
  • Systematic Review and Meta-Analysis of Early Goal-Directed Therapy in Septic Shock (by the the ARISE, ProCESS and ProMISe Investigators) (Intensive Care Med, 2015) [MEDLINE]

  • Meta-Analysis and Trial Sequential Analysis of Early Goal-Directed Therapy in Septic Shock (J Intensive Care Med, 2018) [MEDLINE]
    • Adults with Severe Sepsis and Septic Shock Who Received Early Goal-Directed Therapy Had a Lower Mortality Rate than Those Who Received Usual Care
      • The Benefit May Mainly Be Attributed to Treatments Administered within the First 6 hrs

    • Very Poor Relationship Between CVP and Blood Volume, As Well as the Inability of CVP/DeltaCVP to Predict the Hemodynamic Response to an Intravenous Fluid Challenge
    • Despite Widely-Used Clinical Guidelines Recommending the Use of Central Venous Pressure (CVP), the Central Venous Pressure (CVP) Should Not Be Used to Make Clinical Decisions Regarding Fluid Management

    • Although Authors Identified Some Positive and Negative Predictive Values for Fluid Responsiveness for Specific Low and High Values of Central Venous Pressure (CVP), None of the Predictive Values were >66% for Any Central Venous Pressure (CVP) from 0-20 mm Hg
    • Central Venous Pressure (CVP) in the Normal Range (Especially in the 8-12 mm Hg Range) Does Not Predict Fluid Responsiveness

Clinical Efficacy-Fluid Balance/Targeted Fluid Minimization

  • Trial of Two Fluid Management Strategies in Acute Lung Injury (NEJM, 2006) [MEDLINE]
    • Although There was No Significant Difference in the Primary Outcome of 60-Day Mortality, the Conservative Fluid Management Strategy Improved Lung Function and Shortened the Duration of Mechanical Ventilation and intensive Care without Increasing Nonpulmonary Organ Failures

    • At 90 Days After Randomization, Number of Days Alive without Life Support and Days Alive and Out of the Hospital were Similar in Both Groups
    • Serious Adverse Events were Similar in Both Groups
    • Critique: patients received median of 3 liters of fluid prior to randomization, which could have influenced the results
  • Crystalloid Liberal or Vasopressors Early Resuscitation in Sepsis (CLOVERS) Multicenter Unblinded Superiority Trial of Early Restrictive (Prioritizing Vasopressors and Lower Intravenous Fluid Volumes) or Liberal Fluid (Prioritizing Higher Volumes of Intravenous Fluids Before Vasopressor Use) Management for Sepsis-Induced Hypotension (NEJM, 2023) [MEDLINE]: n = 1,563 (at 60 centers)
    • Less Intravenous Fluid was Administered in the Restrictive Fluid Group than in the Liberal Fluid Group (Difference of Medians -2134 ml; 95% CI: -2318 to -1949), Whereas the Restrictive Fluid Group Had Earlier, More Prevalent, and Longer Duration of Vasopressor Use

    • Six Trials with Predefined Definitions of Serious Adverse Events Demonstrated Relative Risk of 0.95 (97% CI, 0.83-1.07; Low Certainty Evidence)
    • Health-Related Quality of Life was Not Reported
    • In Adult Patients with Sepsis, Lower Intravenous Fluid Volumes Probably Result in Little to No Difference in All-Cause Mortality, as Compared to Higher Intravenous Fluid Volumes
      • However, the Interpretation is Limited by Imprecision in the Estimate, Which Does Not Exclude Potential Benefit or Harm
      • Evidence Suggests Lower Intravenous Fluid Volumes Result in Little to No Difference in Serious Adverse Events

  • Phenylephrine Use Should Be Limited in Sepsis Until Further Data are Available
    • However, the 2012 Surviving Sepsis Guidelines Stated that Phenylephrine was Not Recommended, Except When Norepinephrine is Associated with Arrhythmias, Cardiac Output is High with Low Mean Arterial Pressure, or as Salvage Therapy When Combined Inotropes/Vasopressors Fail to Achieve Mean Arterial Pressure Targets (Grade 1C Recommendation) (2012 Surviving Sepsis Guidelines; Crit Care Med, 2013) [MEDLINE]

Recommendations (Surviving Sepsis Campaign: International Guidelines for Management of Sepsis and Septic Shock 2021) (Crit Care Med, 2021) [MEDLINE]

  • For Adults with Septic Shock, Terlipressin is Not Recommended (Weak Recommendation, Low Quality of Evidence)
  • For Adults with Septic Shock and Cardiac Dysfunction with Persistent Hypoperfusion Despite Adequate Volume Status and Arterial Blood Pressure, Addition of Dobutamine to Norepinephrine or Using Epinephrine Alone is Recommended (Weak Recommendation, Low Quality of Evidence)
    • Dobutamine Should Not Be Used Target a Supranormal Cardiac Output
    • Monitoring Response in Indices of Perfusion to a Measured Dobutamine-Induced Increase in Cardiac Output is Recommended
  • For Adults with Septic Shock and Cardiac Dysfunction with Persistent Hypoperfusion Despite Adequate Volume Status and Arterial Blood Pressure, Levosimendan is Not Recommended (Weak Recommendation, Low Quality of Evidence)
  • For Adults with Septic Shock, Invasive Arterial Blood Pressure Monitoring is Recommended Over Noninvasive Arterial Blood Pressure Monitoring, as Soon as Practical and if Resources are Available (Weak Recommendation, Very Low Quality of Evidence)
  • For Adults with Septic Shock, Starting Vasopressors Peripherally is Recommended to Restore Mean Arterial Pressure, Rather than Delaying Vasopressor Initiation Until a Central Venous Line is Placed (Weak Recommendation, Very Low Quality of Evidence)

    • Primary Composite Outcome of Death in Hospital or Discharge to Hospice Occurred Among 47.2% of Patients Treated with Hydrocortisone-Fludrocortisone vs 50.8% Treated with Hydrocortisone Alone (Adjusted Absolute Risk Difference, -3.7%; 95% CI, -4.2% to -3.1%; P < 0.001)
    • In this Comparative Effectiveness Cohort Study in Adult Patients with Septic Shock Who Began Hydrocortisone Treatment, the Addition of Fludrocortisone was Superior to Hydrocortisone Alone
  • Systematic Review With Bayesian Network Meta-Analysis of Randomized Controlled Trials of Fludrocortisone in Addition to Hydrocortisone in Adult Patients With Septic Shock (Crit Care Med, 2023) [MEDLINE]: n = 95,841 (from 19 studies)
    • Hydrocortisone Plus Fludrocortisone Demonstrated the Lowest Short-Term Mortality vs Placebo (Odds Ratio 0.79; 95% Credible Interval: 0.64-0.99; Number Needed to Treat 21, Range: 12-500; Low Certainty of Evidence) in Terms of Informative Priors
    • Surface Under the Cumulative Ranking Curve Values for Hydrocortisone Plus Fludrocortisone, Hydrocortisone Alone, and Placebo were 0.9469, 0.4542, and 0.0989, Respectively
    • Consistent Results were Observed in Randomized Controlled Trials Alone and Those Using a Daily Hydrocortisone 200 mg Dose
    • Although Gastroduodenal Bleeding or Superinfection Demonstrated No Clear Increase, Hyperglycemia Risk Increased
    • The Odds Ratios were 0.53 for Placebo vs Hydrocortisone Plus Fludrocortisone and 0.64 for Placebo vs Hydrocortisone Alone, with Very Low Certainty of Evidence

Recommendations (American College of Critical Care Medicine Consensus Statement on the Diagnosis and Management of Corticosteroid Insufficiency in Critically Ill Adult Patients, Crit Care Med, 2008) [MEDLINE]

  • General Comments: involved a multi-disciplinary, multi-specialty group from the membership of the Society of Critical Care Medicine, the European Society of Intensive Care Medicine, and international experts in endocrinology
  • Use of Adrenocorticotrophic Hormone (ACTH) Stimulation Test
    • Adrenocorticotrophic Hormone (ACTH) Stimulation Test Should Not Be Used to Identify Those Patients with Septic Shock/ARDS Who Should Receive Glucocorticoids
  • Agents
    • Hydrocortisone (50 mg q6hrs IV for ≥7 Days) is Recommended for Septic Shock
    • Dexamethasone is Not Recommended to Treat Critical Illness-Related Corticosteroid Insufficiency
    • Methylprednisolone (1 mg/kg/day for ≥14 Days) is Recommended in Patients with Severe Early Acute Respiratory Distress Syndrome
  • Administration
    • Glucocorticoids Should be Weaned and Not Stopped Abruptly
    • Reinstitution of Treatment Should Be Considered with Recurrence of Signs of Sepsis, Hypotension, or Worsening Oxygenation
  • Glucocorticoids in the Management of Patients with Community-Acquired Pneumonia, Liver Failure, Pancreatitis, Those Undergoing Cardiac Surgery, and Other Groups of Critically Ill Patients Requires Further Investigation

Recommendations (Surviving Sepsis Campaign: International Guidelines for Management of Sepsis and Septic Shock 2021) (Crit Care Med, 2021) [MEDLINE]

  • For Adults with Septic Shock and Ongoing Vasopressor Requirement, Intravenous Corticosteroids are Recommended (Weak Recommendation, Moderate Quality Evidence)
    • It is Suggested that Intravenous Corticosteroids Should Be Initiated at a Dose of Norepinephrine or Epinephrine ≥0.25 μg/kg/min at Least 4 hrs After Initiation
    • Recommended Hydrocortisone Dosing: 50 mg q6hrs IV (Weak Recommendation, Low Quality of Evidence)
    • The 2012 Surviving Sepsis Guidelines Recommended that if Hydrocortisone is Used, it Should Be Tapered When Vasopressors are No Longer Required (Grade 2D Recommendation) (2012 Surviving Sepsis Guidelines; Crit Care Med, 2013) [MEDLINE]
    • The 2012 Surviving Sepsis Guidelines Recommended that ACTH Stimulation Testing Should Not Be Used to Identify Adults with Septic Shock Who Should Receive Hydrocortisone (Grade 2B Recommendation) (2012 Surviving Sepsis Guidelines; Crit Care Med, 2013) [MEDLINE]

Recommendations (2024 Focused Update: Guidelines on Use of Corticosteroids in Sepsis, Acute Respiratory Distress Syndrome, and Community-Acquired Pneumonia) (Crit Care Med, 2024) [MEDLINE]

  • Administration of Corticosteroids is Suggested for Adult patients with Septic Shock (Conditional Recommendation, Low Certainty Evidence)
    • In Prior 2017 Recommendations
      • Administering Corticosteroids were Not Suggested in Adult Patients with Sepsis without Shock (Conditional Recommendation, Moderate Quality of Evidence)
  • Administration of High Dose/Short Duration Corticosteroids (>400 mg/d Hydrocortisone Equivalent for <3 Days) is Not Recommended for Adult Patients with Septic Shock (Strong Recommendation, Low Certainty) (Strong Recommendation, Moderate Certainty Evidence)
