Initial Management Steps for Sepsis
The initial management of sepsis requires immediate resuscitation with at least 30 mL/kg of IV crystalloid fluid within the first 3 hours, administration of broad-spectrum antimicrobials within one hour of recognition, and rapid identification and control of the infection source. 1, 2, 3
Immediate Actions
Recognition and Assessment
- Perform a thorough clinical examination to identify the source of infection, evaluating physiologic variables including heart rate, blood pressure, arterial oxygen saturation, respiratory rate, temperature, and urine output 2
- Measure lactate levels at the time of sepsis diagnosis and repeat within 6 hours if initially elevated 2, 3
- Diagnose sepsis as early as possible to improve outcomes 1
Antimicrobial Therapy
- Administer IV antimicrobials as soon as possible after recognition and within one hour for both sepsis and septic shock 2, 3
- Obtain appropriate routine microbiologic cultures before starting antimicrobial therapy (if no significant delay >45 minutes) 2
- Use empiric broad-spectrum therapy with one or more antimicrobials to cover all likely pathogens 2
- Plan to narrow antimicrobial therapy once pathogen identification and sensitivities are established and/or adequate clinical improvement is noted 2
Fluid Resuscitation
- Administer at least 30 mL/kg of IV crystalloid fluid within the first 3 hours for patients with sepsis-induced hypoperfusion 1, 3
- Use crystalloids as the fluid of choice for initial resuscitation and subsequent intravascular volume replacement 1
- Consider balanced crystalloids or saline for fluid resuscitation 1
- Continue fluid administration using a challenge technique as long as hemodynamic factors improve 1, 3
- Avoid hydroxyethyl starches for intravascular volume replacement 1, 3
Source Control
- Identify or exclude a specific anatomic diagnosis of infection requiring emergent source control as rapidly as possible 1, 2
- Implement required source control interventions as soon as medically and logistically practical after diagnosis 1, 2
- Remove intravascular access devices that are a possible source of sepsis or septic shock after other vascular access has been established 1
Hemodynamic Support
- Target a mean arterial pressure of 65 mmHg in patients requiring vasopressors 2, 3
- Use norepinephrine as the first-choice vasopressor for patients with persistent hypotension despite adequate fluid resuscitation 2, 4, 5
- Consider adding vasopressin or epinephrine when an additional agent is needed to maintain adequate blood pressure 4
- Avoid dopamine except in highly selected patients with low risk of tachyarrhythmias and absolute or relative bradycardia 4
Ongoing Monitoring
- Reassess the patient frequently to evaluate response to treatment and need for escalation of care 2
- Guide resuscitation to normalize lactate in patients with elevated lactate levels as a marker of tissue hypoperfusion 2, 3
- Monitor for signs of adequate tissue perfusion, including capillary refill time, skin mottling, temperature of extremities, peripheral pulses, mental status, and urine output 2
Common Pitfalls and Caveats
- Delaying antimicrobial therapy beyond one hour can significantly increase mortality - ensure rapid administration 2, 3
- Fluid overresuscitation can lead to respiratory impairment and delay organ recovery - carefully monitor for signs of fluid overload 1, 4
- Failing to identify and control the source of infection promptly can lead to persistent sepsis - prioritize source control within 12 hours when possible 1, 2
- Recent evidence suggests that 20-30 mL/kg of initial fluid resuscitation within the first hour may be associated with reduced 28-day mortality compared to higher volumes 6
- Dynamic measures of fluid responsiveness are preferred over static measures when available to guide ongoing fluid therapy 3, 7
By following this algorithmic approach to sepsis management, focusing on early recognition, prompt antimicrobial therapy, adequate fluid resuscitation, source control, and appropriate hemodynamic support, you can significantly improve patient outcomes in sepsis.
