Brief summary
The purpose of this study is to evaluate if prediction of general anaesthesia level by the Smartpilot® View device can improve the quality of anaesthesia in patients undergoing hip fracture surgery.
Interventions
DEVICEGeneral anesthesia managed by the Smartpilot® View
General anaesthesia managed by the Smartpilot® View device The intervention consists of administering hypnotics and opioids according to effect-site concentrations and interaction model provided by the Smartpilot® View software for the entire duration of general anaesthesia.
DEVICEGeneral anesthesia managed without the Smartpilot® View
General anaesthesia without using the Smartpilot® View device The anesthetic induction will be performed by propofol or sufentanil and atracurium. The maintenance of anesthesia will be directed by desflurane and sufentanil. The dosages of anesthetics are left to the discretion of the doctor and nurse anesthetists in charge of the patient in the operating room.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of time spent in the appropriate anaesthesia zone | participants will be followed for the duration anesthesia, an expected average of 5 hours (from intubation to recovery) for hip fracture surgery | The appropriate anaesthesia zone is defined as a bispectral index between 45 and 65 and a systolic blood pressure between 80 and 140 mmHg |
Secondary
| Measure | Time frame |
|---|---|
| Dose of sufentanil | participants will be followed for the duration anesthesia, an expected average of 5 hours |
| Time to extubation | end of anaesthesia |
| NASA Task Load Index | participants will be followed for the duration anesthesia, an expected average of 5 hours |
| Morphine consumption | participants will be followed for the duration in recovery room, an expected average of 24 hours |
| Dose of propofol | participants will be followed for the duration anesthesia, an expected average of 5 hours |
| Postoperative Quality Recovery Scale | during recovery room (an expected average of 24 hours) and postoperative days 1 and 3 |
| Length of stay | postoperative day 30 |
| Mortality | postoperative day 30 |
| Incidence of awareness with recall during anaesthesia | postoperative day 1 |
