Dobutamine can also be used in hypotensive septic shock to increase cardiac output and correct blood flow to the tissues. Dobutamine is not used as often as epinephrine due to its associated side effects, which include reducing blood flow to the gut. Additionally, dobutamine increases the cardiac output by abnormally increasing the heart rate. Steroids
The use of steroids in sepsis is controversial. Studies do not give a clear picture as to whether and when glucocorticoids should be used. The 2016 Surviving Sepsis Campaign recommends low dose hydrocortisone only if both intravenous fluids and vasopressors are not able to adequately treat septic shock. The 2021 Surviving Sepsis Campaign recommends IV corticosteroids for adults with septic shock who have an ongoing requirement for vasopressor therapy. A 2019 Cochrane review found low-quality evidence of benefit, as did two 2019 reviews.During critical illness, a state of adrenal insufficiency and tissue resistance to corticosteroids may occur. This has been termed critical illness–related corticosteroid insufficiency. Treatment with corticosteroids might be most beneficial in those with septic shock and early severe ARDS, whereas its role in others such as those with pancreatitis or severe pneumonia is unclear. However, the exact way of determining corticosteroid insufficiency remains problematic. It should be suspected in those poorly responding to resuscitation with fluids and vasopressors. Neither ACTH stimulation testing nor random cortisol levels are recommended to confirm the diagnosis. The method of stopping glucocorticoid drugs is variable, and it is unclear whether they should be slowly decreased or simply abruptly stopped.
The defect in the TLR4 gene that led to the endotoxin resistant phenotype was discovered to be due to a mutation in the cytoplasm.Controversy occurred in the scientific community over the use of mouse models in research into sepsis in 2013 when scientists published a review of the mouse immune system compared to the human immune system and showed that on a systems level, the two worked very differently; the authors noted that as of the date of their article over 150 clinical trials of sepsis had been conducted in humans, almost all of them supported by promising data in mice and that all of them had failed. The authors called for abandoning the use of mouse models in sepsis research; others rejected that but called for more caution in interpreting the results of mouse studies, and more careful design of preclinical studies. One approach is to rely more on studying biopsies and clinical data from people who have had sepsis, to try to identify biomarkers and drug targets for intervention. Society and culture
Economics
Sepsis was the most expensive condition treated in United States hospital stays in 2013, at an aggregate cost of $23.6 billion for nearly 1.3 million hospitalizations. Costs for sepsis hospital stays more than quadrupled since 1997 with an 11.5 percent annual increase. By payer, it was the most costly condition billed to Medicare and the uninsured, the second-most costly billed to Medicaid, and the fourth-most costly billed to private insurance.
