Design outcomes

Primary

Measure	Time frame
In this study, the main goal is to determine, if a higher rate of colonoscopies without sedation/ with less sedation can be achieved by using warm water instead of air in patients who start colonoscopy without sedation. Each application of sedative medication is documented. In the end the different amounts of sedation can be compared.	—

Secondary

Measure	Time frame
Ancillary criteria are to investigate the number of required patient turns, the time needed for manual stabilisation of the colon by assistants, demand of sedation(number of BOLI), and patient satisfaction based on the specific technique used (water versus air flow).	—
