Sedation Techniques for Outpatient Colonoscopy
- Conditions
- Colonoscopy
- Interventions
- Device: patient-controlled sedation pumpDevice: target controlled infusion pump
- Registration Number
- NCT04686058
- Lead Sponsor
- Universiti Kebangsaan Malaysia Medical Centre
- Brief Summary
This was a prospective, randomized, single-blind controlled clinical trial comparing three sedative regimens for outpatient colonoscopy.
- Detailed Description
This was a prospective, randomized, single-blind controlled clinical trial comparing target-controlled infusion (TCI) with propofol and patient-controlled sedation (PCS) with propofol, to conventional combination of midazolam and pethidine, in terms of quality and safety of sedation, and patient recovery during outpatient colonoscopy.

Group Intervention Description PCS propofol patient-controlled sedation pump Patient-controlled sedation titrated by the patient to comfort level TCI propofol target controlled infusion pump Target controlled infusion propofol titrated by the investigator intra-procedure, based on the Modified Observer's Assessment of Alertness and Sedation Scale PCS propofol Propofol 10 MG/ML Injection Patient-controlled sedation titrated by the patient to comfort level midazolam and pethidine Pethidine Hydrochloride 50 Mg/mL Solution for Injection Midazolam and pethidine bolus doses administered by the investigator based on clinical parameters and observation TCI propofol Propofol 10 MG/ML Injection Target controlled infusion propofol titrated by the investigator intra-procedure, based on the Modified Observer's Assessment of Alertness and Sedation Scale midazolam and pethidine Midazolam injection Midazolam and pethidine bolus doses administered by the investigator based on clinical parameters and observation
- Primary Outcome Measures
Name Time Method Recovery time to Modified Observer's Assessment of Alertness and Sedation Scale (MOAAS) From time of arrival at the recovery area after completion of colonoscopy, until point of discharge from recovery area, assessed up to 2 hours post arrival at recovery Recovery of patient from sedation when MOAAS 5 is achieved
Recovery time to ambulation From time of arrival at the recovery area after completion of colonoscopy, until the point patient starts to ambulate, assessed up to 2 hours post arrival at recovery Recovery of patient from sedation when patient starts ambulating
Recovery time to discharge From time of arrival at the recovery area after completion of colonoscopy, until the point patient is deemed fit for discharge home, assessed up to 2 hours post arrival at recovery Recovery of patient from sedation when patient is deemed fit for discharge home
Endoscopist satisfaction score After completion of colonoscopy, the endoscopist graded his satisfaction score from the start of colonoscopy, assessed until 2 hours after completion of colonoscopy After completion of colonoscopy, the endoscopist graded on a scale of 1 to 10, ease of the colonoscopy/procedure (1 = very difficult, 10 = very easy), and level of satisfaction (1 = very dissatisfied, 10 = very satisfied) using a 10 cm visual analog scale (VAS).
Patient satisfaction score Patient satisfaction score from start of sedation until point of discharge from recovery assessed until 3 hours from the start of sedation After completion of colonoscopy, the patient graded on a scale of 1 to 10, the level of satisfaction (1 = very dissatisfied, 10 = very satisfied) using a 10 cm visual analog scale (VAS).
Patient willingness to repeat the same sedation technique From patient arrival to recovery post colonoscopy, area until the point of patient discharge, assessed up to 3 hours after arrival at recovery Patient responds yes or no. to willingness of having the same sedation during colonoscopy, in the future
- Secondary Outcome Measures
Name Time Method Rescue analgesic drug requirement From start of sedation, and during the entire duration of colonoscopy, assessed up to 2 hours from the start of sedation Requirement for rescue analgesic or sedative in addition to study drugs/sedatives, during the entire duration of colonoscopy
Total drug consumption Total consumption of all study drugs from the start of sedation, during the entire duration of colonoscopy until completion of colonoscopy, assessed up to 2 hours from the start of sedation Total consumption of all study drugs from the start of sedation, during the entire duration of colonoscopy until completion of colonoscopy
Ease of colonoscopy score during the entire duration of colonoscopy from the start of colonoscopy, assessed up to 2 hours from the start of colonoscopy endoscopist graded on a scale of 1 to 10, ease of procedure (1 = very difficult, 10 = very easy)
Recalled events during colonoscopy Recalled events retrieved from patient, from arrival to recovery area until point of discharge home, assessed up to 2 hours from arrival at recovery The number of recalled events during the entire duration of colonoscopy
Recalled discomfort/ pain during colonoscopy Recalled events of discomfort/pain retrived from the patient, from arrival to recovery area until point of discharge home, assessed up to 2 hours from arrival at recovery The number of recalled events of discomfor/pain during the entire duration of colonoscopy
