- My dad is 61, and reasonably healthy.
- 20 minutes ago, he got stung by a bee, on the ear.
- When he's been stung (or bitten by ants) in the past, the area around the sting/bite has swollen considerably, but he has never gone into anaphylaxis.
- However, I'm concerned that this situation has a larger risk of obstructing the airway, simply because the sting is on his head.
- We removed the stinger within 5 minutes of being stung, and he took a dose of Diphenhydramine (Benadryl).
- He lives in Maricopa, Arizona, US, where (according the the John Hopkins Cornavirus dashboard), there have been 2,491 total COVID-19 cases, and 70 deaths.
- Does anyone know of figure such as "If the patient starts do develop symptoms in their mouth or throat, their risk of full blow anaphylaxis is [X]%?"
- I think that number in particular, is pretty crux-y.
- Which resources should I be referring to.
- How should I be weighing the risks of bringing him to the emergency room in light of the current pandemic?
[Update: it seems like the base-rate of anaphylaxis from bee stings is 3%, when anaphylaxis occurs, it usually starts within within a few minutes.
The key question I have left is if "large local swelling", can block the air ways when it the swelling is on the head or face.]
In such a case, you might get many of the benefits without the covid risks from driving to very close to the ER, then hanging out there and not going in and risking infection unless worse symptoms develop, but being able to act very fast if they do.
From medline plus:
It seems like if you don't have a severe reaction, shortly after the sting, anaphylaxis is pretty unlikely?
But I think that this is with allergens in general, and according to medical news today, swelling from bee stings can occur gradually over the course of 24 or 48 hours.
I'm glad you could already find the answer for it, and I hope your dad gets better.
I'm writing just to say something that has worked for me (I'm also allergic). When I was stung by a wasp, I found that applying a cold compress reduced the swelling considerably, and I recovered in a matter of hours. When it happened before and I didn't use the cold compress, I remember it taking days to recover, and I could not walk properly while it was swelled. Both times I was stung on my ankle.
This paper seems to be exactly what I'm looking for. It deals specifically with airway obstruction as a result of local swelling.
From this factsheet:
According to this paper,
So that seems like a good prior to adjust from.
