Ketamine
Latest review conclusion

Compared with etomidate, ketamine probably results in more hemodynamic instability during the peri-intubation period and appears to have no effect on successful intubation on the first attempt or mortality. However, ketamine results in decreased need for the initiation of vasopressor use and decreases adrenal suppression compared with etomidate.

SAM-E
Latest review conclusion

Our results showed that robotic surgery contributed positively to some perioperative outcomes but longer operative times remained a shortcoming. Better quality evidence is needed to guide surgical decision making regarding the precise clinical targets of this innovation in the next generation of its use.
