How Does Nasal Packing Stop Nosebleeds?

It is not unusual for an ENT or an Emergency Room physician to see a patient with a very bad nosebleed... the kind that can potentially be life-threatening given how much active bleeding is occurring.

In these situations, nasal packing is the fastest and best way of stopping the nosebleed.

For any type of active bleeding, direct pressure tamponades the bleeding thereby stopping it... whether it be a stab wound to the leg or a bad nosebleed. In essence, direct pressure exerts a certain amount of pressure that exceeds the blood pressure preventing blood flow. The corollary being if the amount of direct pressure being exerted is LESS than the blood pressure, bleeding will still occur.

With nasal packing, pressure is exerted by the packing material and pressed against whatever the bleeding source is within the nose.

My personal favorite packing material is called the rapid rhino made by Arthrocare (I have no financial ties to the company). It is in essence a balloon covered by a bio-compatible self-lubricating fabric. This device is inserted into the nose in a deflated state. 
Once fully inserted into the nose, it is than inflated using a standard syringe. Enough air is inflated into the device such that the pressure exerted by the balloon exceeds the blood pressure of the vessels within the nose.

The key point here is that enough pressure must be exerted by the balloon device. If the patient's blood pressure exceeds the balloon pressure, bleeding will still occur and MORE air must be pushed in. As such, in patients with high blood pressure, more air must be inflated into the balloon device to stop a nosebleed compared to a patient with low blood pressure.

So, here is what it looks like to insert a rapid rhino nasal packing.

Step 1: After hydrating the fabric, the nasal packing is placed at entrance of nose.


Step 2: Nasal packing is fully inserted into the nasal cavity.


Step 3: The nasal packing balloon is than inflated with enough air pressure to stop the nosebleed.


Obviously, blood pressure must also be controlled and the nasal packing can be removed in about 3 days for patients not taking any blood thinners or anti-coagulants (coumadin, plavix, ticlid, pradaxa, aspirin, ibuprofen, etc). For those on such medications, packing may need to be kept in place longer.

Is Whispering Bad for Your Vocal Cords???

For most people, the answer is yes according to research publicized in a New York Times article on Feb 7, 2011.

In the mentioned study, out of a group of 100 patients, 69% exhibited increased supraglottic hyperfunction with whispered voice (ie, it was bad for the voice). 18% had no change and 13% had less severe hyperfunction.

As such, though whispering is not bad for everybody, it is for most people and as such, the safest thing to do if the vocal cords are damaged whether by infection or trauma is to rest your voice. If you have to talk, do not whisper, but rather talk in a soft voice.

The best way to think about injured vocal cords is to talk in an analogy. Laryngitis is like a badly sprained ankle. In this scenario, talking is like walking and screaming is like running. So just like you would rest the sprained ankle and not walk on it in order for it to recover as quickly as possible, you should refrain from talking in order for the laryngitis to recover as quickly as possible. Where does whispering fall in this analogy? Probably equivalent to running on a sprained ankle.
