Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To demonstrate in a pilot study the safety and effectiveness during sedation for endoscopic retrograde cholangiopancreatography of the arylcyclohexylamine drug ketamine used in combination with midazolam, as compared to the standard combination of midazolam with pethidine. ; Secondary Objective: To demonstrate the use of side-stream capnography as an adjunct to standard monitoring during sedation for endoscopic retrograde cholangiopancreatography. ;Primary end point(s): The trial will end when 40 to 60 patients have been recruited, approximately half to the study arm of sedation with ketamine and midazolam and approximately half to the control arm of conventional sedation with pethidine and midazolam. | — |
