Septic shock is a condition in medicine in which sepsis is "associated with hypotension or hypoperfusion despite adequate fluid resuscitation. Perfusion abnormalities may include, but are not limited to lactic acidosis; oliguria; or acute alteration in mental status."[1]

Treatment

Vasopressors

Among the choices for pressors, a randomized controlled trial concluded that there was no difference between the biogenic amines norepinephrine (plus dobutamine as needed for cardiac output) versus epinephrine.[2] Similarly, another randomized controlled trial found no difference between vasopressin and norepinephrine.[3]

Corticosteroids

Comparison of major trials of corticosteroids
  CORTICUS, 2008[4] French study, 2002[5]
Patients - onset of shock within the previous 72 hours within the previous 3 hours
Patients - SAPS II score
(higher is sicker)
50 59
Intervention 200 mg/day of hydrocortisone 200 mg/day of hydrocortisone
50 microgram/day fludrocortisone
28-day survival in control group 69% 27%
Trial results negative positive

Corticosteroids, perhaps if combined with a mineralocorticoid, may reduce mortality among patients who have relative adrenal insufficiency[5] Although the largest and most recent randomized controlled trial was negative, its patients were less sick (as evidenced by less stringent inclusion criteria and less mortality in the control group) and mineralcorticoids were not given as a co-treatment.[4]

The lack of mineralocorticoid in the new study may not be important. In the new trial, the total hydrocortisone per day in the new trial is 200 mg. This equates to 200/250 or 0.8 mg (800 microgram) fludrocortisone (see relative potency table for corticosteroids). The French study by Annane used 50 microgram daily of fludrocortisone.[5]

Activated protein C

Recombinant activated protein C (drotrecogin alpha) has been shown in large randomized clinical trials to be associated with reduced mortality (Number needed to treat (NNT) of 16) in patients with multi-organ failure[6] If this is given, heparin should probably be continued.[7]
