All endoscopies were completely successfully. Mean total dose of midazolam in group PK and PN was 0.027±0.005 mg/kg and 0.026±0.005 mg/kg, respectively (p=0.469). Mean total dose of propofol in group PK and PN was 7.28±3.03 mg/kg/h and 8.02±2.99 mg/kg/h, respectively (p=0.451). Mean total dose of ketamine in group PK was 1.49±0.61 mg/kg/h. There were no significant differences in the patient and endoscopist satisfaction, procedural pain and recovery time, but the recovery score at 30 min post-procedure in group PK was significantly lower than group PN (p=0.025). Tolerability of the patient and comfort during insertion in group PN were statistically significantly lower than the patients in group PK. Overall and sedation-related adverse event rate in group PN were also significantly higher than in group PK. However, these adverse events were transient and easily treated with no sequelae.
