An interventional study of Esketamine and Sufentanil in Biliary Tract Diseases and Procedural Sedation and Analgesia, sponsored by Ren Da. Not yet recruiting. Open to participants aged 18 Years to 90 Years. Per ClinicalTrials.gov, last updated 2026-07-14.
Sponsored by Ren Da · Not applicable, Interventional, and Treatment
This study compares two anesthesia medications, esketamine and sufentanil, used together with propofol during ERCP procedures. The goal is to find out which combination provides better safety and comfort for people undergoing ERCP.
Participants will be randomly assigned to receive either esketamine or sufentanil during sedation. Researchers will monitor blood oxygen levels, blood pressure, and recovery time during and after the procedure to evaluate safety and effectiveness.
This randomized controlled trial compares the effects of intravenous esketamine and intravenous sufentanil as adjuncts to propofol sedation in patients undergoing endoscopic retrograde cholangiopancreatography (ERCP).
The study aims to evaluate differences in intraoperative hemodynamic stability, oxygenation, sedation quality, and recovery profiles between the two sedation strategies.
Participants will be randomly assigned to receive either esketamine or sufentanil in combination with propofol during the ERCP procedure. Sedation will be titrated to achieve an adequate level of sedation based on clinical assessment.
Standard monitoring will be applied throughout the procedure, including continuous pulse oximetry and non-invasive blood pressure measurement at predefined time points. Hemodynamic instability, including hypotension and oxygen desaturation, will be managed according to predefined clinical protocols.
Adverse events will be recorded throughout the perioperative period and assessed for severity and relatedness to the study interventions.
The study is designed to reflect routine clinical anesthesia practice while systematically comparing two commonly used adjunct analgesic strategies for procedural sedation in ERCP patients.
59 studies on the registry are indexed under Biliary Tract Diseases; 12 are open to participants now.
This study's planned enrollment of 530 is above the median of 84 across 37 interventional studies indexed under Biliary Tract Diseases.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Participants receive intravenous esketamine in combination with propofol for procedural sedation during ERCP. Esketamine is administered as an adjunct analgesic during induction of sedation, while propofol is continuously infused and titrated according to clinical sedation requirements.
Drug: Esketamine
Participants receive intravenous sufentanil in combination with propofol for procedural sedation during ERCP. Sufentanil is administered as an adjunct analgesic during induction of sedation, while propofol is continuously infused and titrated according to clinical sedation requirements.
Drug: Sufentanil
Intravenous esketamine is administered as an adjunct analgesic during induction of sedation for ERCP. It is used in combination with continuously infused propofol, with dosing titrated to achieve adequate procedural sedation. This regimen differs from the comparator arm in that esketamine is used as the primary analgesic agent instead of an opioid.

Incidence of intraoperative hypoxemia
Hypoxemia is defined as peripheral oxygen saturation (SpO₂) \< 90% lasting ≥ 10 seconds. Peripheral oxygen saturation (SpO₂) were recorded at six predefined time points: T0, T1, T2, T3, T4, T5.
Time frame: Six time points:T0, upon arrival in the procedure room (baseline); T1, after anesthesia induction; T2, when the endoscope passed the vocal cords; T3, when the endoscope passed the duodenal papilla; T4, at the end of the procedure; and T5, upon recovery.
Incidence of intraoperative hypotension
Hypotension was defined as a reduction in mean arterial pressure (MAP) of ≥30% from baseline or a systolic arterial pressure (SAP) \<90 mmHg. Systolic arterial pressure (SAP), diastolic arterial pressure (DAP), and mean arterial pressure (MAP) were recorded at six predefined time points: T0, T1, T2, T3, T4, T5.
Time frame: Six time points:T0, upon arrival in the procedure room (baseline); T1, after anesthesia induction; T2, when the endoscope passed the vocal cords; T3, when the endoscope passed the duodenal papilla; T4, at the end of the procedure; and T5, upon recovery.
induction time
Time from administration of the study drug to successful insertion of the endoscope
Time frame: During anesthesia induction
Recovery time
Time from discontinuation of propofol administration to recovery of consciousness, defined as achieving an Observer's Assessment of Alertness/Sedation (OAA/S) score of 5. The score ranges from 1 to 5, with higher scores indicating a higher level of alertness. Recovery was defined as achieving an OAA/S score of 5 (responds readily to name spoken in a normal tone).
Time frame: From the end of the procedure to recovery from sedation
Patient body movements
Number of patient body movements during the procedure requiring additional propofol administration or interfering with the procedure
Time frame: Throughout the procedure
Endoscopist satisfaction
Endoscopist satisfaction with sedation conditions, assessed using a 10-point numeric rating scale (1 = extremely dissatisfied, 10 = extremely satisfied).
Time frame: Immediately after completion of the procedure
Patient satisfaction
Patient satisfaction with the anesthesia experience, assessed using a 10-point numeric rating scale (1 = extremely dissatisfied, 10 = extremely satisfied)
Time frame: Before discharge from the recovery room (PACU)
Total propofol dose
The total amount of propofol administered during the procedure, including the induction dose and additional doses required to maintain adequate sedation
Time frame: From induction of sedation to the end of the procedure
Aldrete recovery score
Recovery from sedation was assessed using the modified Aldrete recovery score, which evaluates activity, respiration, circulation, consciousness, and oxygen saturation. The score ranges from 0 to 10, with higher scores indicating better recovery
Time frame: Upon arrival at the post-anesthesia care unit (PACU) and before discharge from PACU
Airway intervention
The need for airway interventions to manage sedation-related respiratory compromise, including chin lift, jaw thrust, oral airway insertion, or mask ventilation during the procedure
