For the [[operating room]] management, the basis is the surgical [[suite]], and evaluation can be divided into the duration of [[anesthesia]], [[operation time]], [[operating room time]], and [[operating room preparation time]]. Anesthesia duration is divided into four moments: anesthetic [[induction]], [[maintenance]], [[awakening]], and [[recovery]]. The operative time consists of [[dieresis]], [[hemostasis]], [[exeresis]], and [[suture]]. [[Operating room]] time includes patient stay, from arrival to exit. Operating room preparation time ([[turnover]]) is the time between one patient leaving and another entering, including cleaning and replacing the necessary material. The lengthiest stage during a procedure is anesthesia.
