Providing enough analgesia and amnesia without excessive sedation is an art form which is extremely useful in rural practice. Often only one physician and one nurse are involved, and pains must be taken to avoid general anesthesia with the need for airway protection on the one hand, and oligoanalgesia with the need for assured amnesia on the other. Of course you often have to do the actual procedure as well. One of the most useful aids to simple pediatric orthopedics in my career has been the use of IM ketamine.
The use of propofol remains controversial in the hands of non-anesthetists. The new Emergency Medicine literature continues to be reassuring, but full anesthetic protocols in terms of equipment and monitoring, along with essential skills in life support remain advisable for management of apnoea or hypotension.
This outline only covers drug dosing for procedural sedation. Each facility should have a protocol for setup, monitoring and discharge criteria.
