About this study

The purpose of this pilot study was to compare two commonly employed intravenous drug combinations; I) nitrous oxide, midazolam, fentanyl, and ketamine and II) the same combination with substitution of propofol for ketamine, for use during wisdom teeth extraction. Measures of recovery, amnesia testing 20 minutes after induction and after completion of recovery tests, patient satisfaction, and surgeon satisfaction will be evaluated. The data from this pilot study will be used to obtain preliminary estimates of effect sizes and to select primary and secondary endpoints for the design of a larger scale and more definitive trial of the two anesthetic approaches.

Read the detailed description

The widespread application of various ambulatory anesthetic techniques has paralleled the rapid rise of ambulatory surgery. It has been estimated that over half of all elective surgery is performed in an ambulatory setting. In addition, well over 3,000,000 intravenous sedations are administered in dental offices annually where local anesthesia is obtainable to control intraoperative pain. These intravenous sedation techniques have historically been an integral part of pain and anxiety control in the dental setting and have now gained widespread application in all of ambulatory surgery. A number of intravenous anesthetic techniques have been developed to achieve sedation levels ranging from conscious sedation where patients respond purposefully to verbal commands to deep sedation where patients cannot be easily aroused and protective reflexes may be altered. The goal of all of these techniques is to create a comfortable environment for the patient and a cooperative patient for the surgeon. Ideal technique should pose minimal physiologic challenge to the patient while providing amnesia for the procedure. Most of the intravenous sedation techniques in widespread use include a combination of drugs. These combinations function in an additive if not synergistic way. The pharmacological properties of their constituents achieve this ideal. The most frequently used drug when used alone and the most common to the various combinations is midazolam, a benzodiazepine. Midazolam has been shown to provide safe sedation with reliable anterograde amnesia. The duration of these effects is dose dependent. A short acting narcotic, usually fentanyl, is often times included to increase sedation levels and to add a modicum of analgesia. Other short acting agents can also be included to deepen the sedation level. These agents are usually added in incremental doses as the surgical setting requires. Both propofol and ketamine can induce general anesthesia but in significantly smaller doses provide additional sedation. These two agents come from different drug classes. Proponents of each cite advantages and disadvantages. Nitrous oxide is also commonly used in the dental setting.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Patient Satisfaction

    Patient satisfaction was assessed using a patient evaluation survey administered following the procedure just prior to discharge. The survey consisted of 3 questions, 1 categorical and 2 ordinal. For purposes of this study, the 2 ordinal measures: "How do you feel now?" and "I would recommend this type of intravenous sedation to my family/friends" will be scored from 1-3 and 1-4, respectively for an overall possible scoring range of 2-7. Higher scores are associated with increased patient satisfaction. Satisfaction scores will be summarized by study arm.

    Measured: Postoperatively, approximately 1 hour on day of procedure

  2. Surgeon Satisfaction

    Surgeon satisfaction will be assessed by a surgeon's satisfaction survey administered following the procedure. The survey consisted of 3 questions which asked the surgeon to assess their level of satisfaction with the sedation regimen during local anesthesia, during the surgery, and overall satisfaction. Each of the three were rated as 1 ("Poor"), 2 ("Adequate"), or 3 ("Excellent") for an overall possible scoring range of 3-9. Higher scores are associated with increased surgeon satisfaction. Surgeon satisfaction scores will be summarized by study arm.

    Measured: Postoperatively, approximately 1 hour

  3. Recovery - Paper Test

    Recovery will be assessed using a simple repeated measure paper and pencil test (PS Form 9a). This test presented participants with 25 rows of numbers. Each row consisted of a circled number at the beginning of the string of numbers. Patients were asked to cross out each number in a row that is like the circled number. The number of successfully completed rows were tabulated for each patient and change from baseline was summarized by study arm.

    Measured: Change from preoperatively to postoperatively, approximately 2-3 hours total on day of procedure

  4. Recovery - One Leg Standing Test

    Recovery will also be assessed by way of a 30 second one leg standing test administered prior to and following induction of anesthesia. The percentage of participants who are able to stand for at least 30 seconds will be summarized by study arm.

    Measured: Change from preoperatively to postoperatively, approximately 2-3 hours total on day of procedure

  5. Amnesia - Visual Stimuli

    Amnesia will be evaluated by interrupting the procedure momentarily at specific intervals (approximately 20 minutes after induction and after completion of recovery test). Amnesia for visual stimuli will be assessed by having the patient verbally identify common objects (i.e., cup, pen, tape, and keys) presented during surgery. Patients will be asked to recall the items postoperatively. Recall of visual stimuli will be summarized by study arm using basic descriptive statistics.

    Measured: Intraoperatively and postoperatively, up to 1-2 hours on day of procedure

  6. Amnesia - Tactile Stimuli

    Amnesia will be evaluated by interrupting the procedure momentarily at specific intervals (approximately 20 minutes after induction and after completion of recovery test). Amnesia for tactile stimuli will be assessed by touching the patient with a pin on one of their four limbs and asking for recall. Recall of tactile stimuli will be summarized by study arm using basic descriptive statistics.

    Measured: Intraoperatively and postoperatively, up to 1-2 hours on day of procedure

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 27 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Patient Satisfaction (time frame: Postoperatively, approximately 1 hour on day of procedure). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06867068, which also lists 25 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Mar 2026.
