About this study
patients may appear serious perineal itching, after injection of dexamethasone sodium phosphate injection its incidence is about 25% ~ 100%, and the incidence of the discomfort in females was much higher than that of the maleTo investigate the effect of propofol pretreatment on perineal pruritus induced by dexamethasone sodium phosphate injection and explore the possible machanisms.
Read the detailed description
40 patients scheduled for selective surgery,aged 18-65years,ASA physical status I~II,BMI 18~30kg/m2 were selected in this study.The patients were equally randomized into two groups: propofol (P) group and normal saline (N) group, 20 cases in each group. Before anesthesia induction, M group received intravenous injection of 0.3mg/kg propofol , while N group received corresponding intravenous normal saline of the same volume. After 1 min, both groups received intravenous injection of dexamethasone sodium phosphate injection of 10mg. The anesthesiologist assessed perineal irritation in both groups and recorded Ramsay scores,the number of cases, visual analogue scale(VAS) scores ,duration of itching and observed the occurrence of adverse reactions such as dizziness, hypotension and respiratory depression in the two groups.

Secondary outcomes (1)
the occurrence of adverse reactions
the occurrence of adverse reactions such as dizziness, hypotension and respiratory depression in the two groups

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Propofol and normal saline in people with Pruritus, run by Yangzhou University at 1 site in China.
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 1 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 25 Feb 2022. 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 China. 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. Some participants in this study may receive a placebo. 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?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
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?
visual analogue scale(VAS) scores (time frame: in 3min). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 25 Feb 2022; AzTrials last refreshed its copy on 7 Nov 2026.
