Revision as of 08:55, 29 January 2010
In medicine, septic shock is a form of sepsis with "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]
Complications
Myocardial dysfunction
Transient myocardial dysfunction may occur in 59% of patients and may resolve within 12 days.[2]
Treatment
Antibiotics
Choosing appropriate antibiotics is associated with better outcomes. Recommendations for choosing antibiotics are available.[3]
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.[4] Similarly, another randomized controlled trial found no difference between vasopressin and norepinephrine.[5]
Corticosteroids
Practice guidelines
Clinical practice guidelines by American College of Critical Care Medicine conclude "hydrocortisone should be considered in the management strategy of patients with septic shock, particularly those patients who have responded poorly to fluid resuscitation and vasopressor agents."[6] In a meta-analysis that was included with the guidelines found greater shock reversal (at day 7) with hydrocortisone and a (insignficant) trend towards benefit in mortality".[6]
Regarding whether the use of steroids should be confined to patients with relative adrenal insufficiency, the guidelines state "ACTH stimulation test should not be used to identify those patients with septic shock or ARDS who should receive GC".[6]
Randomized, controlled trials
The most recent meta-analyses of randomized controlled trials conclude benefit.[7][6] In a meta-analysis that was included with the American College of Critical Care Medicine guidelines found greater shock reversal (at day 7) with hydrocortisone and a (insignficant) trend towards benefit in mortality".[6] Adding fludrocortisone may not help according to a more recent randomized controlled trial.[8]
| Trial | Patients | Interventions | Outcomes | Results for patients with relative adrenal insufficiency |
Comments | |
|---|---|---|---|---|---|---|
| Control | Intervention | |||||
| CORTICUS[9] 2008 |
499 patients • Onset of shock ≤ 72 hours • Adrenal insufficiency: 47% • SAPS II score: 50 • Intratracheal intubation: 100% • Arterial lactate: 4.0 |
200 mg/day of hydrocortisone for 7 days | 28-day mortality | 36% | 39% | In a post hoc analysis, the sickest patients ("systolic blood pressure persisting at less than 90 mm Hg within 30 hours") had better outcomes when given corticosteroids.[9] |
| French study[10] 2002 |
300 patients • Onset of shock ≤ 3 hours • Adrenal insufficiency: 76% • SAPS II score: 59 • Intratracheal intubation: 88% • Arterial lactate: 4.5 |
200 mg/day of hydrocortisone for 7 days 50 microgram/day fludrocortisone |
28-day mortality | 63% | 53% | |
Although the largest and most recent randomized controlled trial (CORTICUS[9]) 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 as compared to the French trial be Annane[10]. In a post hoc analysis of the CORTICUS study, the sickest patients ("systolic blood pressure persisting at less than 90 mm Hg within 30 hours") had better outcomes when given corticosteroids.[9]
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.[10]
Activated protein C
Recombinant human activated protein C, also called drotrecogin alpha, has been shown in a randomized controlled trial to be associated with reduced mortality (number needed to treat (NNT) of 16) in patients with multi-organ failure[11] If this is given, heparin should probably be continued.[12]
Tissue factor pathway inhibitor
Recombinant human tissue factor (thromboplastin) pathway inhibitor, also called tifacogin, was found not to be effective in a randomized controlled trial.[13]
Polymyxin B hemoperfusion
Polymyxin B hemoperfusion may be beneficial according to a systematic review of randomized controlled trials.[14]
