In one of the most disturbing revelations in the newly released Senate report on the CIA's "enhanced interrogation" program, the CIA was found to have used "rectal feeding" and rectal rehydration to impose their will on detainees.
"CIA medical officers discussed rectal rehydration as a means of behavior control," the report reads. "As one officer wrote, '[w]hile IV infusion is safe and effective, we were impressed with the ancillary effectiveness of rectal infusion on ending the water refusal in a similar case."
In other words, while using a saline drip delivered via IV worked just as well, the CIA found that detainees were more likely to end resistance after the use of rectal rehydration.
The same officer described the procedure, writing that "regarding the rectal tube, if you place it and open up the IV tubing, the flow will self-regulate, sloshing up the large intestines."
