Sure, but even there you need some reasonable sample size. i.e. a sample of 1 won't be sufficient and more importantly it needs to be reproducible. Inject 1 patient and they wake up, but if you inject 10 others and nothing happens and it may not be effective (not that it's definitely not effective). This would require a then a larger sample size.
