It was likely that no anaesthetic or sedatives were given as the bodies of the hosts were spread throughout the room, some still restrained.

Curiously even after the Chestbursters were taken into cells for study, the bodies of the crew were left where they died in the room, with no regard for disposing of the bodies.
