About this study
Official title: Comparison of Propofol-ketamine and Propofol-fentanyl Sedation in Short-term Gynecological Cases
Comparison of fentanyl-propofol and ketamine-propofol combination for sedation in brief gynecological cases
Our study aimed to evaluate ketamine-propofol and fentanyl-propofol combinations in short-term gynecological cases in terms of hemodynamic parameters, recovery, complications, patient and physician comfort.
Read the detailed description
Procedural sedation is widely used in various medical procedures worldwide, aiming to suppress consciousness adequately and provide sufficient analgesia while preserving the patient's cardiorespiratory function during painful or unpleasant interventions (1,2). Many drugs are used alone or in combination for this purpose (e.g., benzodiazepines, opioids such as fentanyl and remifentanil, midazolam, ketamine, propofol, dexmedetomidine) (6). This prospective, randomized, double-blind study will evaluate the effectiveness of ketamine-propofol and fentanyl-propofol combinations during short-term gynecological procedures by comparing the frequency of lower extremity movements in sedated patients.
Participants eligible for the study will include individuals aged 18-65 with American Society of Anesthesiologists (ASA) physical status I or II undergoing short gynecological procedures lasting less than 30 minutes. Participants with allergies to study medications, obesity, or behavioral disorders will be excluded. All participants will provide written informed consent the day before the procedure.
Enrolled participants will be divided into two groups: Group K, receiving ketamine and propofol, and Group F, receiving fentanyl and propofol. Heart rate (HR), arterial blood pressure (ABP), peripheral oxygen saturation (SpO2), Ramsey Sedation Score( 1: Awake; agitated or restless or both, 2: Awake; cooperative, oriented, and tranquil,3: Awake but responds to commands only, 4: Asleep; brisk response to light glabellar tap or loud auditory stimulus,5: Asleep; sluggish response to light glabellar tap or loud auditory stimulus, 6: Asleep; no response to glabellar tap or loud auditory stimulus)( RSS), and Facial Pain Score(0:No hurt- 10:Hurts worst (FPS) will be evaluated at five time points: T1 (pre-induction), T2 (1 minute post-induction), T3 (3 minutes post-induction), T4 (end of surgery), and T5 (30 minutes postoperatively).
) In Group K, ketamine-propofol will be prepared in a 1:1 ratio (both 10 mg/mL) in the same syringe, while in Group F, fentanyl (1-2 mcg/kg) and propofol (1 mg/kg) will be prepared separately. Sedation will be initiated with 0.2 mL/kg of ketofol. Surgery will commence if RSS > 4; if the desired sedation level is not achieved, a rescue dose of 0.5 mg/kg propofol bolus will be administered.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
KetamineDrug
Also called GROUP A
0.5 mg/kg ketamine + 1 mg/kg propofol, Ramsey Sedation Score > 4 will be targeted. For this, if necessary, additional iv 0.5 mg/kg propofol will be administered.
FentanylDrug
Also called GROUP B
1 mcg/kg fentanyl + 1 mg/kg propofol will be administered. Ramsay Sedation Score will be targeted to be > 4. For this, if necessary, additional iv 0.5 mg/kg propofol will be administered.
| Study group | Role | What they receive |
|---|---|---|
| ketamine-propofol | Active comparator | 0.5 mg/kg ketamine + 1 mg/kg propofol will be administered. Ramsey Sedation Score will be targeted to be > 4. For this, if necessary, additional iv 0.5 mg/kg propofol will be administered. Receives: Drug: Ketamine |
| fentanyl-propofol | Active comparator | 1 mcg/kg fentanyl + 1 mg/kg propofol will be administered. Ramsay Sedation Score will be targeted to be > 4. For this, if necessary, additional iv 0.5 mg/kg propofol will be administered. Receives: Drug: Fentanyl |
What is being measured
The primary outcome is the main question the study is designed to answer.
Surgical satisfaction
Surgical satisfaction survey:
Was the level of sedation sufficient during local anesthesia administration? Was the level of sedation sufficient throughout the surgical procedure? Was your verbal communication level with the patient sufficient? Would you recommend this sedation method to other surgeons for this surgical procedure? Would you accept using the same sedation technique for your next surgical procedure with the patient? Scoring: Ratings are based on a scale of 0 to 2, where 0 indicates 'not at all', 1 indicates 'somewhat', and 2 indicates 'completely'. The scores are evaluated on a scale from the lowest '0' to the highest '10'."
Measured: Postoperative procedure
Incidence of lower extremity movement during the procedure
The incidence of lower extremity movement indicative of inadequate sedation or analgesia during the procedure
Measured: intraoperative
Secondary outcomes (1)
Adverse events (such as nausea, vomiting, airway obstruction, apnea, desaturation, respiratory depression, hypotension and bradycardia)
he side effects occurring during the intraoperative and postoperative periods include:
Recall events (recall of events during surgery) Apnea (holding breath for >15 seconds) Desaturation (SpO2 < 96%) Jaw thrust maneuver Bradycardia (heart rate < 50 beats/min) Skin rash
Measured: 30th minute postoperative

The record lists 1 site in Turkey (Türkiye). 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.
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?
Surgical satisfaction (time frame: Postoperative procedure). The study lists 2 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 NCT06412861, which also lists 2 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 20 Aug 2024; AzTrials last refreshed its copy on 8 Nov 2026.
