KETAMINE, KIDS, AND DOSING
While legal authorities looked on, two white men injected a young brown-skinned child with a big dose of ketamine.
They then handcuffed him and deliberately shoved his face underwater.
The child lived.

Actually, this happened to *12 children*, all of whom lived.
And the two men, an anesthesiologist and a veterinarian, are the closest thing to a Neil Armstrong/Bruce Wayne hero mashup you could imagine.

Let’s talk about the #ketamine dosing
Ketamine is taking some of the heat for deaths in police ± EMS custody.
The heartbreaking case of Elijah McClain is only *one* of the most well-known cases.

Was McClain killed by too high a dose of ketamine?
McClain weighed 65 kilos, so the dose was 7.7 mg per kilogram.
Standard IM dosing can be up to 5 mg/kg, so about 50% higher than recommended. https://www.thedenverchannel.com/news/investigations/aurora-paramedics-gave-maximum-dose-of-ketamine-even-when-patients-weight-was-unknown

OTOH, kids who have received 5-100 - fold overdoses (no type) have done just fine, no deaths.
Pretty safe drug even when you give a funk-ton of it! https://www.sciencedirect.com/science/article/abs/pii/S0196064499800511

Back to Thailand.
How did the docs calculate the right ketamine dose for each kid?
A scale?
Broselow tape?
Nah.
Sorta sounds like they held up a thumb and squinted

Let's try to back-calculate their mg/kg ketamine doses
The Thai kids were 11-16 years old, from a rural background, definitely lower socio-economic context, probably means they were overall lower weight...

So ballparking their range of weights.
At 18 years of age, the average weight of an urban, *higher* socio-economic-status Thai boy is 58 kg... https://pubmed.ncbi.nlm.nih.gov/2738501/
At 18 years of age, the average weight of an urban, *higher* socio-economic-status Thai boy is 58 kg... https://pubmed.ncbi.nlm.nih.gov/2738501/
… while 10-11 y.o. Thai boys are are about 30-36 kg. https://content.sciendo.com/view/journals/abm/8/6/article-p799.xml?language=en
So roughly:
The loading dose could range from 125/58 = 2.2 mg/kg for the biggest kid, to 100/30 = 3.3 mg/kg for the smallest.
If they choose a 125 mg syringe for a 30 kid, could be up to 4.2 mg/kg!

If they choose a 125 mg syringe for a 30 kid, could be up to 4.2 mg/kg!
And that’s just the loading dose!
Each kid was supposed to get maintenance half-dose injections on their way out of the cave.
So the total dose could have gone from 4.4 mg/kg, maybe all the way up to 8.25 mg/kg.
Hard to say. They weren't doing a lot of charting.

Feel free to check my math
Oh BTW
These kids didn’t swim out of the cave, they were *dragged*
The doctors handcuffed their arms, shackled their feet, slapped on a full-face Scuba mask, and pulled them through the cave as an inert bundle.

What about monitoring the sedated patients?
Ha.
They didn’t have cardiac monitoring, end-tidal CO2, or even an oxygen saturation.
They monitored for “physically moving to the point of being a problem”

So these kids got stout doses of ketamine, while handcuffed underwater, with basically no cardiovascular monitoring.
And they all lived.
And they all lived.
Elijah was in a modern mobile ICU, with sophisticated monitoring equipment and oxygenation/ventilation devices.
He died.
He died.
