About this trial
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.

Treatments tested in this trial
Esketamine
DrugIntravenous 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.
Sufentanil
DrugIntravenous sufentanil 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 sufentanil is used as the opioid-based analgesic instead of esketamine.
Treatment groups
Trial outcomes
Primary outcomes
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.
Secondary outcomes
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.
Other outcomes
induction time
Time from administration of the study drug to successful insertion of the endoscope
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).
Patient body movements
Number of patient body movements during the procedure requiring additional propofol administration or interfering with the procedure
Endoscopist satisfaction
Endoscopist satisfaction with sedation conditions, assessed using a 10-point numeric rating scale (1 = extremely dissatisfied, 10 = extremely satisfied).
