Abstract:
Background:It is commonly recommended that patients should refrain from driving for 24 hours after sedation for endoscopy,however,this recommendation has been queried recently. Aims:To investigate the effect of sedation on early postoperative cognitive function in patients undergoing endoscopy. Methods:One hundred adult patients undergoing sedative esophagogastroduodenoscopy ( EGD ) were randomly recruited, and another 100 adult patients undergoing conventional EGD were served as controls. All patients had an education level more than 9 years. Cognitive function was assessed by number connection test-A( NCT-A),number cancellation test and digit symbol test( DST)before propofol sedation or the beginning of endoscopic procedure and was reassessed when the discharge criteria were met. If the results obtained were inferior to those before EGD,a third assessment was taken 30 minutes later until the results recovered or being superior to the baseline levels. Results:All patients completed the first and second assessment,and 124 patients had taken the third assessment. When the discharge criteria were met,result of number cancellation test was inferior to that before EGD in sedation group( P =0. 000 ). Furthermore,the results were analyzed by grouping with age,number cancellation test in young patients and NCT-A in elderly patients were inferior to that before EGD,respectively(P=0. 000 and P =0. 025 ). In control group,none of the results were inferior to those before EGD. The results of the third assessment recovered or being superior to the baseline levels. Conclusions:Early postoperative cognitive dysfunction at discharge is common in patients undergoing endoscopy using propofol sedation,but the impairment will recover by a prolonged staying calm before discharge. The optimal time for discharge and resuming driving remains to be further studied.
