Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of our study is to determine if monitoring sedation (how asleep patients are under general anesthesia) using a device called a Sedline Monitor affects the amount of anesthesia patients receive.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The main objective of this study is to determine if monitoring sedation using the FDA approved device, Sedline Monitor, affects the amount of anesthesia patients 65 or older receive during surgery. Reducing the anesthetic dose could result in less exposure of anesthetic medications to a high-risk patient population as well as a potential reduction in cost. Subjects will be randomized into either a control group or study group and have the Sedline Monitor placed on their head before the start of their already scheduled surgery. During the surgery, subjects in the control group will receive standard anesthesia care and the study group will receive anesthetic drug doses guided by Sedline Monitor processed EEG characteristics. When the surgery is complete, the Sedline Monitor will be removed and subject participation will be finished. The study team will also collect information about subjects from their medical records and use it for this study.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Study Group

Prior to the induction of anesthesia, the Sedline monitor will be placed on the patient's head to ensure the monitor is working properly. For those in the study group, the monitor will be in full view of the anesthesiologist administering the anesthetic.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Patients undergoing a scheduled surgery (laparotomy, hepatobiliary surgery, gynecologic surgery, and/or urologic surgery procedures) at Indiana University Health University Hospital that is expected to have at least a 3 day post-operative hospital stay.
* ASA class 1, 2, 3, or 4.
* Age 65 years or older.
* Male or Female
* Surgical procedure requiring general anesthesia.

Exclusion Criteria

* Any previous diagnosis of dementia or other cognitive impairment.
* Any patient undergoing emergency surgery.
* Any patient undergoing surgery who is currently an inpatient.
* Patient refusal to participate in study.
* Any patient undergoing surgery that would prevent placement of the Sedline monitor leads (for example - surgery on the patient's forehead/scalp).
* Any physical, mental, or medical conditions which, in the opinion of the investigators, may confound the ability to assess the patient for delirium in the post-operative period.
