What is the primary goal of metabolic resuscitation in sepsis?
Restore cellular metabolism and reduce organ dysfunction.
Immediately eradicate the infecting pathogen.
Increase antibiotic concentration in plasma.
Replace lost blood volume.
Metabolic resuscitation aims to correct cellular energy deficits and support organ function rather than directly targeting pathogens or fluid volume. By restoring cellular metabolism, it reduces the downstream effects of sepsis on organ systems.
Which vitamin is primarily used as an antioxidant in sepsis metabolic resuscitation protocols?
Vitamin C
Vitamin D
Vitamin K
Vitamin B12
Vitamin C has potent antioxidant properties that help scavenge free radicals and support endothelial function in sepsis. Other vitamins listed do not have the same high-dose antioxidant role in critical care resuscitation.
What is the main biochemical role of thiamine in septic patients?
Cofactor for pyruvate dehydrogenase to reduce lactate buildup.
Stimulate cortisol production.
Act as a direct vasoconstrictor.
Enhance neutrophil chemotaxis.
Thiamine is a critical cofactor for pyruvate dehydrogenase, which converts pyruvate to acetyl-CoA and prevents lactate accumulation. Without sufficient thiamine, anaerobic metabolism and lactic acidosis worsen in septic patients.
Which corticosteroid is most commonly recommended in sepsis metabolic resuscitation?
Hydrocortisone
Dexamethasone
Prednisone
Methylprednisolone
Hydrocortisone is preferred in septic shock protocols due to its mineralocorticoid activity and support of vasopressor responsiveness. Other corticosteroids are not routinely used for this metabolic approach.
Which metabolic marker is most indicative of tissue hypoperfusion in sepsis?
Elevated blood lactate
High C-reactive protein
Elevated procalcitonin
Increased white blood cell count
Elevated lactate is a direct indicator of anaerobic metabolism and tissue hypoperfusion. While CRP and procalcitonin reflect inflammation or infection, they do not measure perfusion status.
What is the commonly used intravenous dose of vitamin C in sepsis metabolic resuscitation according to the Marik protocol?
1.5 grams every 6 hours
0.5 grams every 6 hours
3 grams every 12 hours
2 grams every 8 hours
The Marik protocol recommends 1.5 g of IV vitamin C every 6 hours to achieve antioxidant and endothelial support. Lower or less frequent dosing has not shown the same effects.
What is the typical intravenous thiamine dosage used in combination with vitamin C for metabolic resuscitation?
200 mg every 12 hours
50 mg every 8 hours
100 mg once daily
500 mg every 6 hours
A thiamine dose of 200 mg IV every 12 hours is commonly used to correct deficiency and support aerobic metabolism. Lower daily doses may be insufficient in septic shock.
When should corticosteroids be initiated in septic shock during metabolic resuscitation?
After persistent hypotension despite adequate fluids and vasopressors
Immediately upon diagnosis of sepsis
Only after 72 hours of antibiotic therapy
When C-reactive protein levels exceed 100 mg/L
Guidelines recommend starting hydrocortisone when septic shock remains refractory to fluids and vasopressors. Early blanket use or waiting for CRP changes does not align with evidence-based approach.
Which mechanism best describes how vitamin C benefits septic patients?
Scavenges free radicals and restores endothelial integrity
Blocks proinflammatory cytokine production at the transcriptional level
Directly kills bacteria in the bloodstream
Enhances renal excretion of lactate
Vitamin C acts as an antioxidant, neutralizing reactive oxygen species and supporting endothelial barrier function. It does not directly kill pathogens or alter transcription of cytokines in this context.
What is a common consequence of thiamine deficiency in septic patients?
Lactic acidosis due to impaired aerobic metabolism
Hyperglycemia from increased gluconeogenesis
Excessive cortisol release
Enhanced protein synthesis
Thiamine deficiency impairs pyruvate dehydrogenase activity, leading to pyruvate accumulation and lactic acidosis. It does not directly cause hyperglycemia or alter cortisol in sepsis.
What minimum percentage of lactate clearance within the first 6 hours is often targeted in septic shock management?
>10% reduction
>5% reduction
>20% reduction
No change
A lactate clearance of over 10% in the first 6 hours is associated with improved outcomes. Smaller reductions may not signify adequate resuscitation, and expecting >20% is often unrealistic.
What is the primary role of hydrocortisone in sepsis metabolic resuscitation?
Enhance vasopressor sensitivity and modulate inflammation
Provide substrate for ATP production
Scavenge reactive oxygen species
Act as a diuretic to reduce fluid overload
Hydrocortisone improves vasopressor responsiveness by upregulating adrenergic receptors and dampens excessive inflammation. It is not an energy substrate or antioxidant.
Which marker best reflects mitochondrial function and aerobic metabolism in septic patients?
Lactate-to-pyruvate ratio
C-reactive protein
Procalcitonin
Serum creatinine
The lactate-to-pyruvate ratio indicates the balance between anaerobic and aerobic metabolism and thus mitochondrial function. CRP and procalcitonin reflect inflammation, not cellular respiration.
What is the proposed synergy between vitamin C and corticosteroids in sepsis?
Vitamin C restores glucocorticoid receptor function, enhancing steroid effects.
Corticosteroids increase renal excretion of vitamin C.
They compete for the same plasma transporters.
Steroids inhibit intestinal absorption of vitamin C.
Vitamin C supports glucocorticoid receptor integrity, improving cellular responsiveness to corticosteroids in septic shock. The other options have no evidence-based support.
What is the impact of delaying metabolic resuscitation with vitamin C and thiamine beyond 24 hours?
Reduced clinical benefit and slower lactate clearance
Improved outcomes due to late immune modulation
No change in patient outcomes
Prevention of adrenal suppression
Studies suggest early administration (within 24 hours) yields more significant lactate clearance and hemodynamic improvement. Delayed therapy shows diminishing returns.
A 68-year-old patient in septic shock remains hypotensive on norepinephrine at 0.2 µg/kg/min after 3 liters of fluids. Which metabolic resuscitation strategy is most appropriate?
Initiate combined IV vitamin C, IV thiamine, and IV hydrocortisone.
Administer high-dose IV vitamin D only.
Increase fluids without metabolic interventions.
Start only broad-spectrum antibiotics and monitor.
In refractory septic shock despite fluids and vasopressors, the triple therapy of vitamin C, thiamine, and hydrocortisone is indicated to support cellular metabolism and vasopressor sensitivity. Monotherapy or fluid-only strategies miss key metabolic support.
In a patient with stage 4 chronic kidney disease, how should vitamin C dosing be adjusted during metabolic resuscitation?
Reduce frequency to 1.5 g every 12 hours to lower oxalate risk.
Maintain 1.5 g every 6 hours without change.
Increase to 3 g every 6 hours to overcome clearance issues.
Discontinue vitamin C entirely.
Renal impairment increases the risk of oxalate accumulation from high-dose vitamin C; reducing frequency helps mitigate this while still providing antioxidant benefit. Complete discontinuation may forgo potential benefit.
A septic patient shows normal lactate but an elevated lactate-to-pyruvate ratio. What does this indicate?
Persistent mitochondrial dysfunction despite adequate perfusion.
Over-resuscitation with fluids.
Early improvement in perfusion.
Renal failure causing false ratios.
An elevated lactate-to-pyruvate ratio with normal lactate suggests impaired mitochondrial oxidative phosphorylation rather than hypoperfusion. The other options do not explain this metabolic pattern.
Clinical trials of high-dose vitamin C (6 g/day) in septic shock have most consistently demonstrated which benefit?
Reduced duration of vasopressor support
Increased 28-day mortality
Higher incidence of acute kidney injury
No change in organ failure scores
Meta-analyses of trials using 6 g/day have shown a shortened need for vasopressors in septic shock. There is no consistent evidence of increased mortality or kidney injury in these studies.
A patient develops confusion and ophthalmoplegia on day 5 of ICU stay after minimal thiamine supplementation. What is the best next step?
Administer high-dose IV thiamine (500 mg TID) for suspected Wernicke's encephalopathy.
Obtain a head CT before any intervention.
Switch to oral thiamine at the same dose.
Start intravenous haloperidol for delirium.
Confusion and eye movement abnormalities suggest Wernicke's encephalopathy, requiring urgent high-dose IV thiamine. Imaging or antipsychotics delay critical therapy.
