Remimazolam Combined With Oliceridine for Sedation in Elderly Patients Undergoing Gastrointestinal Endoscopy (RMZ-OLI-ENDO)

Descrição detalhada
This is a clinical study conducted at the Baoshan Branch of Renji Hospital, Shanghai Jiao Tong University School of Medicine. The study will strictly adhere to ethical guidelines, and all research activities will be carried out after receiving full approval from the Ethics Committee.
Elderly participants will be enrolled based on predefined inclusion criteria with comprehensive vulnerability assessments. During the gastrointestinal endoscopy procedure, vital signs, particularly oxygen saturation (SpO2) and its duration of depression, will be monitored closely. To address potential educational bias in cognitive assessments, the study will utilize the Mini-Mental State Examination (MMSE) stratified by years of education alongside the Montreal Cognitive Assessment (MoCA) to comprehensively evaluate postoperative cognitive outcomes. Follow-up assessments will be systematically conducted at designated time points (e.g., 1 week, 1 month, 3 months, and 6 months) post-procedure.

Intervenção / Tratamento |
|---|---|
|
Experimental: Remimazolam + Oliceridine Group
Patients in this group will receive a combination of remimazolam and oliceridine for sedation during painless gastrointestinal endoscopy.
Remimazolam will be administered intravenously for induction and maintenance of sedation, titrated to achieve an appropriate depth of anesthesia.
Oliceridine will be administered intravenously to provide stable analgesic cooperation and reduce sedation-related adverse events.
|
Administered intravenously for sedation induction and maintenance during gastrointestinal endoscopy.
The dosage will be titrated according to the patient's sedation depth and clinical response.
Outros nomes:
Administered intravenously before or during the procedure to provide stable analgesic cooperation and optimize procedural sedation quality in elderly patients.

Comparador Ativo: Active Control Group
Patients in this group will receive standard remimazolam monotherapy (or remimazolam combined with traditional opioids) for sedation during painless gastrointestinal endoscopy.
remimazolam will be administered intravenously to induce and maintain the sedation required for the endoscopic procedure, adhering to standard clinical anesthesia management protocols.
|
Administered intravenously for sedation induction and maintenance during gastrointestinal endoscopy.
The dosage will be titrated according to the patient's sedation depth and clinical response.

Medidas de resultados primários
Medida de resultado |
Descrição da medida |
Prazo |
|---|---|---|
|
Incidence of hypoxemia
Prazo: From initiation of sedation induction to completion of the gastrointestinal endoscopic procedure, approximately 30 minutes.
|
The proportion of participants who experience at least one episode of hypoxemia during procedural sedation for gastrointestinal endoscopy.
Hypoxemia is defined as peripheral oxygen saturation (SpO₂) < 90%.
SpO₂ will be continuously monitored throughout the observation period.
|
From initiation of sedation induction to completion of the gastrointestinal endoscopic procedure, approximately 30 minutes.

Descrição da medida |
Prazo |
|---|---|---|
|
Incidence of Hypotension
Prazo: From the pre-induction baseline assessment to transfer to the post-anesthesia care unit, up to 1 hour.
|
The proportion of participants who experience at least one episode of hypotension during procedural sedation.
Hypotension is defined as a decrease in mean arterial pressure (MAP) of more than 20% from the pre-induction baseline.
MAP will be recorded at baseline and monitored throughout the observation period.
|
From the pre-induction baseline assessment to transfer to the post-anesthesia care unit, up to 1 hour.
|
|
Sedation success rate
Prazo: From the start of sedation induction to the completion of the endoscopic procedure
|
The proportion of patients who achieve a satisfactory sedation depth (MOAA/S score ≤ 1) without the need for rescue sedative medications.
|
From the start of sedation induction to the completion of the endoscopic procedure
