Given Ketamines often very negative effects on the human body (I'm only speculating here) there is a dosage that is referred to by junkies as "Key Holing" where you know you are alive but are unable to move, open your eyes or speak. If that was the dose given...what a pair of brilliant minds It must have taken to correctly give each boy dosage suitable for their body weight to take them to the edge of that state. The good docs were good..no..best..no..very best.
ETA - Ketamine seems to wear off quite quickly - not sure of the effect on humans but I've seen my colts gelded in the paddock after Ketamine and get up and stagger for a few minutes then be walking perfectly (if painfully) within ten minutes.
Based on the Tham Luang sump profile, the worst one was at the beginning. the rest were manageable. Once the boys went through the first sump, the rest would be like strolling downhills, so-to-speak.
