The aim of this clinical study was to compare the efficacy and safety of two different doses of remimazolam with propofol for sedation during colonoscopy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Patients and methods<\/jats:title>\n                    <jats:p>\n                      225 subjects, aged 18 to 80\u2009years, with American Society of Anesthesiology physical status I-III, were scheduled to undergo colonoscopy. All the subjects were randomly assigned to three groups, Low-Rem group (low dose remimazolam, 0.15\u2009mg\/kg, iv,\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200975), High-Rem group (high dose remimazolam, 0.2\u2009mg\/kg, iv,\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200975), and Propofol group (propofol 2\u2009mg\/kg, iv,\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200975). Every individual in this trial was given nalbuphine hydrochloride (0.2\u2009mg\/kg, iv) before administration of remimazolam or propofol. The primary outcome was the success rate of sedation. Haemodynamic parameters and adverse events were recorded to evaluate safety. Satisfaction of sedation from patients, anesthesiologists and gastroenterologists were also recorded.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The success rate of colonoscopy procedure was 100% in both High-Rem and Propofol groups, but it was 89% in Low-Rem group (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&amp;lt;\u20090.05). Furthermore, the induction time of anesthesia was shorter in Propofol group, when compared to the Low-Rem group and the High-Rem group (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&amp;lt;\u20090.05). The recovery time in Low-Rem group, High-Rem group, and Propofol group was 2.33, 2.43, and 3.21\u2009min (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&amp;lt;\u20090.05) respectively, and the time of discharge was 25.00, 25.01, and 27.56\u2009min (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&amp;lt;\u20090.05) respectively. Simultaneously, the incidence of adverse events such as hypotension, bradycardia, and respiratory depression in the remimazolam groups were significantly lower than that in the propofol group. No significant differences were observed among the three groups in Ramsay scale, BPS-NI scale, and Limb movement classification. Moreover, patients, anesthesiologists, and gastroenterologists were all satisfied with the sedation process.\n                    <\/jats:p>\n                  <\/jats:sec>\n
