What is the purpose of administering corticosteroids in septic shock?

Administering corticosteroids in septic shock primarily serves to reduce inflammation and restore immune function. In the context of septic shock, there is a pronounced inflammatory response that can lead to tissue damage and organ dysfunction. Corticosteroids, such as hydrocortisone, act as anti-inflammatory agents, helping to modulate the immune response.

By dampening the excessive inflammation, corticosteroids can help stabilize blood pressure, improve vascular responsiveness, and enhance the overall ability of the body to respond to infection. Furthermore, they play a role in counteracting the effects of relative adrenal insufficiency that can occur in critical illness, thus ensuring that the body's stress response is adequately supported.

The other options do not align with the therapeutic role of corticosteroids in septic shock. For instance, increasing blood viscosity, sedating the patient, or improving lung capacity are not the primary outcomes of corticosteroid administration in the management of septic shock.
