Nasal Foreign Body

Nasal foreign bodies are surprisingly common. The technique is not too dissimilar to that of removing auricular foreign bodies. In theory, they might be hidden behind a turbinate and tricky to see - and therefore tricky to remove.

1. Mother's Kiss
This works in 60% of cases. Occlude patent nostril. Get Mum to blow into the mouth. You can do this with a BVM if needed - but be careful the pressure isn't too high.

2. Suction
Like with FBs in the ear, gentle suction, can help. I guess glue could too - although I haven't seen any case reports of this.

3. Curved Needles
If you can't find one, as we can never find them in the ED, bend a green needle, and that should help!

4. Foley Catheter
Inflate baloon with 0.5 - 3ml water or air. Insert it behind the foreign body, and then pull. I've never tried this, but it seems to be really frequently used outside the UK!

Ear Foreign Bodies

Extracting foreign bodies from the ear can be very painful, and it is easy to impact them where the auditory canal narrows. 75% of patients with ear foreign bodies are younger than eight.

To start with:
- Check if there's a tympanic membrane perforation. If you can't see whether there is or not, that makes things trickier.
- Position the patient comfortably and securely
- Consider anesthetising the ear - some lignocaine dripped in may well help. Blocks don't tend to be too helpful - if this fails, think about general anaesthesia or sedation.
- Check whether you should be removing this. ENT should help with button batteries, sharp objects, tightly wedged FBs, and FBs you can't remove after multiple attempts.
- When successfully removed, double check you've removed it. Consider prophylactic antibiotic drops.

Potential Methods: 
1. Forceps Removal
If the FB is "graspable" this can be useful.

2. Irrigation
This is especially useful if there is a live insect in the ear. The insect must be killed with alcohol, 2% lignocaine or mineral oil - but hopefully you can check there is no tympanic membrane perforation first. Once the insect is dead, suction might remove it more effectively than grasping or forceps as this can cause shedding. Until the insect is dead, remember it might try to fly towards the otoscope light - this can be uncomfortable for the patient!
Don't irrigate button batteries in the ear.
Don't irrigate organic matter that might swell, and get wedged.
Don't forget to use warm water - as the patient won't thank you if the water is cold, as it can cause vertigo and vomiting. If you're having trouble directing the irrigation, think about getting a cannula (needle out) connected to a syringe (that you can gently flush).

3. Modified Suction
We don't have microsuction like ENT do, but cutting a 12Fr suction catheter short, and then applying gentle suction, may help. Equally, cutting the soft tubing from a butterfly needle, and using that for suction may help.

4. Glue
A bit of wound glue on the end of a syringe or Q tip can adhere to the foreign body and pull it out. You're going to have to be pretty convinced you're going to get the Foreign Body out, and not just stick the FB further to the ear canal! If you do this, it might be worth putting an ear speculum on the foreign body, then guiding the glue in that way - it protects the rest of the ear canal. You really do need a compliant patient.

5. Magnets
A small magnet may help remove a magnetic foreign body.

Collapsed Neonates

Resuscitate
As per appropriate
Adrenaline 10mcg/kg

Prostin -  
    - 5 ng/kg/min if clinically well
    - 20 ng/kg/min if unstable or absent femoral pulses
    - 50-100 ng/kg/min if no response
Apnoea common: 1st hr of Rx, dose
Hypotension may occur with high dose

Prostin
- 5 ng/kg/min if clinically well
- 20 ng/kg/min if unstable or absent femoral pulses
- 50-100 ng/kg/min if no response
Apnoea common: 1st hr of Rx, dose

Hypotension may occur with high dose

Think about Causes
Infection
Group B strep, E Coli - PROM, maternal GBS, fever in labour
Herpes Simplex - GCS, coagulopathy, ALT, family cold sores
MRSA - Unresponsive 1st line antibiotics,+ contact

Cardiac
Coarctation aorta - Systolic arm/leg gradient > 20 mmHg
Hypoplastic Left heart - Poor pulses –may be pink= pulm. overcirculation
Transposition (TGA) - Preductal sats < post ductal sats
TAPVD (obstructed) - Shocked & cyanosed/CXR plethoric
SVT  - HR>220 despite fluid, f ixed HR, narrow QRS
Myocarditis - Cardiac failure, tachycardia, small QRS

Injury 
Intracranial bleed  - Focal neuro signs, fontanel le , retinal bleeds
Intrabdominal bleed - Unexplained anaemia, abdominal bruising

Cardiac

Metabolic
Vomiting, reduced GCS, hypoglycaemia
Stop the feeds. Give fluid and dextrose as highly likely to be fluid depleted
