Recently, a new software program for anesthesia has been developed, called Smart Pilot View. This program monitors the patient, the anesthetic drugs given, and the calculated depth of the anesthesia. The purpose of this study is to determine whether the use of this program improves the quality of anesthesia.
||Observational Model: Case Control
Time Perspective: Prospective
||Utility of the Smart Pilot View in Clinical Practice: A Two Center Prospective Observational Study
Primary Outcome Measures:
Secondary Outcome Measures:
- Total anesthetic drug doses [ Time Frame: up to 1 week From start of induction until discharge from post-anesthesia care unit (PACU) ] [ Designated as safety issue: No ]
- Mean intra-operative Noxious Stimulation Response Index (NSRI) [ Time Frame: 1 day During surgery (until skin closure) ] [ Designated as safety issue: No ]
The Noxious Stimulation Response Index (NSRI) is based on a hierarchical interaction propofol-remifentanil model. With this model, the predicted propofol and remifentanyl concentrations can make a prediction about a respons to a certain stimulus, such as shaking and shouting, or a noxious stimulus.
- Number of doses of vasoactive substances [ Time Frame: up to 1 week From start of induction until discharge from post-anesthesia care unit (PACU) ] [ Designated as safety issue: No ]
The number of doses of vasoactive substances given to maintain an adequate perfusion pressure.
- Number of events with motor and vegetative (tearing, sweating) responses [ Time Frame: up to 1 week From start of induction until discharge from post-anesthesia care unit ] [ Designated as safety issue: No ]
The total number of events in which the patient displays vegetative reactions such as tearing and sweating, in respons to a noxious stimulus during surgery.
- Recovery times (skin closure to extubation; skin closure to orientation) [ Time Frame: up to 1 week From end of surgery (skin closure) until discharge from post-anesthesia care unit (PACU) ] [ Designated as safety issue: No ]
The time it takes for the patient to recover from anesthesia: the time from skin closure until the patient is sufficiently awake to be extubated, and the time from skin closure until full orientation of the patient.
- Early postoperative pain control measured by visual analog scale and total morphine dose [ Time Frame: up to 1 day From end of surgery (skin closure) until discharge from post-anesthesia care unit (PACU) ] [ Designated as safety issue: No ]
Assess the adequacy of pain control during the early postoperative stage, measured by the visual analog scale and the total dose of morphine immediately postoperatively and during PACU stay.
- Workload of anesthesist, measured by the NASA Taskload Index [ Time Frame: up to 1 day From start of induction until transportation to PACU ] [ Designated as safety issue: No ]
Assess the workload the anesthetist experiences while working with the Smart Pilot View
