Achieving colonoscopy under general anaesthesia entails the problem of ambulatory-care anaesthesia, in particular because perception of @entity1 's recovery determines to some extent the length of monitoring following colonoscopy. The aims of the study was to assess the quality of @entity1 's recovery after a colonoscopy under general anaesthesia while using @entity1875 , by means of psychomotor-tests. METHODS--Colonoscopy was performed in 40 @entity1 according to the following anaesthetic protocol: induction: @entity1875 2 mg/kg, continuous support: @entity1875 10 mg/kg/h i.v. with a 50 mg bolus in case of insufficient sedation; series of 3 psychomotor-tests were performed the day before and 1 hour, 3 hours and 6 hours after colonoscopy. The 3 psychomotor-tests studied: coordination (Newman test), time-space orientation and short-term memory. RESULTS--Forty @entity1 , 25 females and 15 males, underwent colonoscopy with general anaesthesia for an average time-period of 22 +/- 11 min. The mean dose of @entity1875 used was 286 +/- 102 mg. Awakening was complete in all @entity1 , according to physical criteria such as @entity1662 and cardiovascular status, 20 min after receiving colonoscopy. The average psychomotor-tests results over time were (as percentages of original values) (*P < 10(-3); **P < 0.05): [table: see text] At 6 hours, 35 @entity1 (87.5%) had recovered to their original performance and at 3 hours, 30 @entity1 (75%) retained 90% their former state as measured with 3 psychomotor-tests. Neither by age or sex nor by @entity1875 doses used or length or anaesthesia, the study population differed significantly. CONCLUSION--Three hours after colonoscopy under general anaesthesia using @entity1875 , 30 @entity1 (75%) had recovered at least 90% to their initial performances. Newman test was the most disturbed but there was no predictive factor for the quality of recovery. Psychomotor-tests may be useful before authorizing early discharge after colonoscopy under general anaesthesia but other recommendations about conditions of discharge after sedation must be also implemented.
