Management of Septic Shock in a Patient with Necrotizing Fasciitis

Vasopressor Therapy

The Society of Critical Care Medicine recommends norepinephrine as the first-line vasopressor for septic shock due to necrotizing fasciitis, with a target mean arterial pressure (MAP) of 65 mmHg 1, 2, 3
Norepinephrine should be administered through central venous access when possible, though peripheral administration is acceptable temporarily while central access is being established, as suggested by medical guidelines 4
If the patient remains hypotensive despite norepinephrine, vasopressin (up to 0.03 U/min) can be added to either raise MAP or decrease norepinephrine dosage, according to the Intensive Care Medicine journal 2, 3
Epinephrine can be considered as an alternative second agent if additional vasopressor support is needed, starting at 0.05 mcg/kg/min and titrating up to 2 mcg/kg/min as needed, based on recommendations from Intensive Care Medicine 2
Dopamine should only be considered in highly selected patients with low risk of tachyarrhythmias or with bradycardia, as stated in Intensive Care Medicine 2, 3
Phenylephrine should be reserved for salvage therapy when other vasopressors have failed, according to Critical Care Medicine 1

Fluid administration should be continued using a challenge technique, giving additional fluid boluses only if hemodynamic parameters improve, as recommended by medical guidelines 4, 5
Balanced crystalloids rather than normal saline should be used to avoid hyperchloremic metabolic acidosis, based on suggestions from medical guidelines 4, 5
Monitoring for signs of fluid overload such as pulmonary crackles, increased jugular venous pressure, and worsening respiratory function is essential, as stated in medical guidelines 4

If the patient shows evidence of persistent hypoperfusion despite adequate fluid loading and vasopressor therapy, dobutamine (up to 20 μg/kg/min) can be considered, according to Intensive Care Medicine 2, 7
For patients who remain in refractory shock despite adequate fluid resuscitation and high-dose vasopressors, IV hydrocortisone at a dose of 200 mg/day can be considered, based on recommendations from Intensive Care Medicine 2, 7
Placement of an arterial catheter as soon as practical for continuous blood pressure monitoring and frequent blood sampling is recommended, as suggested by Intensive Care Medicine and medical guidelines 2, 4

Delaying vasopressor initiation in fluid-refractory hypotension increases mortality, according to Intensive Care Medicine and medical guidelines 3, 4
Overreliance on static measures like central venous pressure alone to guide fluid therapy should be avoided due to poor predictive ability for fluid responsiveness, as stated in medical guidelines 4, 5
Fluid overresuscitation should be avoided as it can delay organ recovery, prolong ICU stay, and increase mortality, based on recommendations from medical guidelines 4, 5
