Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

With voluntary participation, this study requires participants to complete a self-administered cognitive evaluation (SAGE) before surgery to assess baseline cognitive impairment and early dementia; vital signs will be documented prior to surgery. During surgery, participants will receive a standardized general anesthesia regimen as described in the protocol. Several parameters will be measured during surgery, including bispectral monitoring to measure processed EEG. After surgery, fitness for cognitive evaluation will be determined by the Richmond Agitation-Sedation Scale (RASS) scale, and then emergence delirium will be assessed using the CAM-ICU scale. Fitness for discharge from PACU will be determined by an Aldrete score of 9 or more. Postoperative pain will be assessed using the 11-point Numeric Rating Scale (NRS-11). Postoperative nausea and vomiting (PONV) level will also be documented. Postoperative Delirium (POD) assessment will be achieved by administering the memorial delirium assessment scale (MDAS) twice a day starting on day 1 through day 3 postoperatively. Pain NRS-11 score and PONV levels will also be documented at each visit. For microRNA testing, blood probes will be collected in 5mL purple top tube at surgical preadmission and post-surgery days one, two and three. Risks associated with participating in this study include normal risk associated with having surgery and general anesthesia; no greater than minimal risk is associated with blood collection. For the participant, there are no immediate anticipated benefits for participating in this study. The importance of the knowledge that is expected to result includes lower post-operative complications as a result of post-operative delirium, faster recovery, and shorter hospital stay.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
OTHER: Subjects undergoing radical cystectomy
Subjects involved in the study will be evaluated with various non-invasive assessments including the Richmond Agitation-Sedation Scale, pain assessments on a Numeric Rating Scale (NRS-11), and CAM-ICU scale. Blood draws will also take place in order to perform microRNA testing in all subjects participating in the trial. Standardized anesthetic care as described by the approved protocol will be followed for each subject included in this trial.
Behavioral: Assessments
These cognitive assessments will be utilized during the study to evaluate cognitive levels comparing prior to surgery and post-operatively in order to determine if the subject is delirious. BIS monitoring will be utilized for all subjects.
Other Names:
  • SAGE scale, Memorial Delirium Assessment Scale
Procedure: Blood Draw
Subjects will have blood draws at surgical preadmission visit, Day 1, Day 2, and Day 3 post surgery only; one tube containing approximately one teaspoon (5 mL) of blood will be drawn at each visit.
Other: Standardized Anesthetic Care
Standardized anesthetic care will be provided as described by the protocol for each subject consented for this trial.
Other Names:
  • Anesthetic Regimen

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Post-operative delirium
Time Frame: up to 3 days post-operatively
Evaluate the incidence of and risk factors for POD in patients undergoing radical cystectomy utilizing the Memorial Delirium Assessment Scale.
up to 3 days post-operatively

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
microRNA expression
Time Frame: up to 3 days post-operatively
A secondary aim of the study is to obtain estimates and variances of the difference in microRNA expression between 2 groups: delirious patients and non-delirious patients.
up to 3 days post-operatively
