About this study

The purpose of this study is to clarify whether or not a low-dose propofol infusion can effectively prevent postoperative nausea and vomiting (PONV) in patients who have a documented history of PONV and/or motion sickness.

Read the detailed description

Propofol is administered as both low dose and as sole anesthetic in patients with history of PONV and/or motion sickness. But efficacy of one dose over the other is not studied. This study plans to clarify if propofol in low dose is as effective as its administration as sole anesthetic in patients with history of PONV and/or motion sickness

Being tested
Hybrid anesthesia (propofol + sevoflurane), Propofol only TIVA

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Hybrid anesthesia (propofol + sevoflurane)Drug

    General anesthesia maintained with a continuous low-dose propofol infusion (25 mcg/kg/min) combined with sevoflurane. Anesthetic depth was titrated to a bispectral index (BIS) target of 40-60. No other hypnotic or sedative agents were permitted.

  • Propofol only TIVADrug

    General anesthesia maintained exclusively with intravenous propofol infusion, without the use of volatile anesthetics. Propofol dosing was titrated to maintain a bispectral index (BIS) target of 40-60. No other hypnotic or sedative agents were permitted

What is being measured

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

  1. Number of Subjects Experiencing Post-Operative Nausea/Vomiting (PONV)

    Postoperative nausea and vomiting (PONV) within 24 hours was defined as any episode of nausea, retching, or vomiting occurring from PACU discharge up to 24 hours after surgery. Data were collected using standardized patient questionnaires and follow-up telephone interviews conducted at 24 hours after surgery.

    Measured: 24 hours

Secondary outcomes (2)
  1. Episodes of Post Operative Nausea/Vomiting (PONV)

    PONV in the post-anesthesia care unit (PACU) was defined as any episode of nausea, retching, or vomiting occurring between PACU admission and discharge. Events were documented by PACU nursing staff as part of routine postoperative care.

    Measured: PACU

  2. Use of Antiemetics

    Use of rescue antiemetics was defined as administration of any antiemetic medication beyond standardized prophylaxis (dexamethasone and ondansetron), either during the post-anesthesia care unit (PACU) stay or within 24 hours after surgery. Antiemetic use was obtained from the medical record in the PACU and from patient self-report during standardized follow-up at 24 hours postoperatively. The outcome was analyzed as a categorical variable and reported as the number and percentage of participants requiring rescue antiemetics.

    Measured: 24 hours

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Hybrid anesthesia (propofol + sevoflurane) and Propofol only TIVA in people with Post-operative Nausea and Vomiting, run by Milton S. Hershey Medical Center at 1 site in United States.

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 5 inclusion and 4 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 14 Aug 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 14 Aug 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Subjects Experiencing Post-Operative Nausea/Vomiting (PONV) (time frame: 24 hours). 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 NCT05759481, which also lists 1 linked publication.

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 14 Aug 2026.
