As part of the effort to rescue the 12 boys and their soccer coach from Tham Luang cave last year in Thailand, rescue divers gave the boys "unspecified doses of ketamine," according to CNN.

According to details of the rescue released in a medical journal Thursday, the boys were given unspecified doses of ketamine, also known as party drug Special K, by the rescue divers as they were taken out of Tham Luang cave.
Reports at the time had suggested that the children, who had been trapped for two weeks, were sedated during the operation, but officials gave few details.
"We had to use the means that could keep the children not to be panicky while we were carrying them out," Thai Navy SEAL commander Rear Adm. Arpakorn Yookongkaew told CNN shortly after the rescue. "Most importantly, they are alive and safe." …
The medics said ketamine was a good choice to give to the boys, given the risk of hypothermia, as ketamine impairs shivering and is associated with smaller drops in core body temperature.
