B) acute; histamines and cytokines

Mordercai: And so these patients will also present with lip, tongue and facial swelling, but they do not have any rash. They don’t have itching or IgE to carry out all that stuff is absent, and so this is not a histamine reaction. And so it’s not like with a type one response where you’re going to give antihistamines right away. This is more supportive care and get their airway control.

FFP Airway maintenance C1 inhibitor concentrate Epinephrine; Glucocorticoids Antihistamines Secondary

Mordecai: Now FFP needs to be given to re establish the intravascular volume and then C1 inhibitor concentrate because the issue is a lack of C1 or that compliment one protein and then epinephrine given for cardiovascular support. But then our antihistamines and Glucocorticoids, as I said, they’re not our first line.They’re not as helpful, but they definitely don’t hurt.You’re going to do everything in your power to reduce inflammation.

Q

What effect do inhalation agents have on the immune system? (Select 2 that apply.)

A. Stimulate natural killer (NK) cells
B. Suppress NK cells
C. Enhance phagocyte function
D. Impair phagocyte function
E. Increase the production of red blood cells

A

B. Suppress NK cells → Induce apoptosis of T-cells

D. Impair phagocyte function

it’s unclear what their impact is on tumor cells, but some studies do show that sevoflurane stimulates renal cell carcinoma but also it inhibits small cell carcinoma and so. Just something to keep in the back of your mind if your patient has renal cell carcinoma.
