Guys if it is in size, what are the pediatric size and the adult size? and is the size the same as the diameter in mm?
like... size 5 is = 5 mm diameter?
I'm not sure what the typical adult sizes are as I am a peds nurse, but here is how the sizing works in the Shiley and Bivona trachs:
Example: "3.0 Neo Shiley": 3.0 refers to mm Id (mm of inner diameter). There is also an outer diameter measurment expressed as mm Od. We only document the mm Id when documenting the trach size.
Example: "4.5 Ped Bivona": Again 4.5 refers to the mm Id.
On the outside of the box of a brand new sterile trach, the size is written in large bold print, ex: "4.0 PED". The specifics such as the inner and outer diameters are written in the fine print on the package insert. The size of the trach is also written on the flange of the trach itself (at least on the Shiley's and Bivona's) and will also just say for example, "4.0 PED".
Shiley and Bivona are two different styles of trachs. Bivonas are used when the child is also on a vent. Shileys are mostly used if the child is not vented. Shiley's can
be used with a vent, just not as convenient as the Bivona.
Neo and Ped refer to the length
of the trach. Neo's are shorter and Ped's are a little longer. Bivona also makes a Ped Long, which is slightly longer than the reg Ped size. And if you ever needed to know that exact length, this is also written on the package insert and expressed in mm.
There is no inner cannula for these style of trach's. We change the whole trach out once per week and as needed for plugging. Shiley's are disposable, we insert a brand new sterile one each week. The Bivona's are reusable. At least 2 are kept in the home to change them out. They are rinsed free of any secretions, then "sterilized", by bringing a pot of water to a boil, removing from the heat source, then placing the trach in the water for 20 minutes, air dried and placed in a clean baggy for use for the next trach change. Obviously this is home care, and the procedures are way different in the hospital.
The smallest size I see in the pediatric population are 3.0 Neo, and the largest size is usually 4.5 Ped. I do have one client who is the size of an adult and he wears a 5.5.
Hope this helps.
