Detailed Description
In this protocol, the investigators will report the percentage of case time in hypotension (defined as Mean arterial pressure (MAP) < 65mmHg). The target MAP will be set at 70mmHg, except for neuro embolisation case where MAP can be higher. The investigators want to demonstrate that the closed-loop system can prevent hypotension at this specific set point.
The Investigators have shown this to be the case in simulation studies and in-vivo animal studies (under submission) but not yet experimentally in a clinical setting. Investigators will recruit their patients from the surgical record that that require a mini-invasive or a non-invasive cardiac output monitoring (EV1000 monitoring using the Flotrac or clearsight system) ; either high risk patients undergoing high risk surgery (vascular-cardiac- Major Abdominal or renal transplant, neuro-endo-vascular surgery (aneuvrysm) and require mechanical ventilation and consent to participate in the study will be included in the study.
The investigators will also test the system in a short series of patients in the ICU setting ( critically ill patients): ideally in 3-4 "types" of patients ( septic patients, neuro ICU patients, ARDS patients and postoperative patients( ideally intubated patients or sedated patients) .The target mean arterial pressure can be different from the 70 mmHg of the surgical patients especially for the neurologic patients (head trauma injury patients or neuro-endovascular surgical patients). In these two subgroups of patients, the target MAP can even vary during the case depending on the surgeons requests (neuro radiologists) or depending on cerebral autoregulation.
Participants will receive standard patient care in that in no way will their anesthetic or surgical procedure will be altered as part of the study, with the exception of vasopressor administration. Fluids will be given as goal directed therapy using the assisted fluid management software present in the EV1000 monitor (only for vascular and abdominal cases).
The closed loop (automated) system will use an infusion pump (Q-Core) and a controller (a computer run index and algorithm developed by Sironis) to make frequent, regular and accurate adjustments to the amount of vasopressor infusion rate the patient receives using feedback from standard operating room monitors at ERASME HOSPITAL Data from this study will also be retrospectively compared to subjects case matched to evaluate differences in MAP time in target, total amount of vasopressor received, and patient outcomes (for patients undergoing high risk surgery and/or neuro endovascular patients)

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
EXPERIMENTAL: Closed-loop
Study patients will receive a baseline crystalloid infusion of 3 cc/kg/hr and all additional fluid management will be performed manually using the assisted fluid management sofware from the EV1000 monitor.
A closed-loop system will automatically administer vasopressor based on the predefined target MAP chosen by the anesthesiologist in charge of the patient
|
Vasopressor admnistration in the closed loop group will be performed via a closed loop (automated) system that will use an infusion pump (Q-Core) and a controller (a computer run index and algorithm developed by Sironis) to make frequent, regular and accurate adjustments to the amount of vasopressor the patient receives using feedback from standard operating room monitors.
