Abstract:
Objective:To evaluate the anesthetic efficacy of remiazolam combined with alfentanil in the patients undergoing painless gastroscopy.Methods:A total of 400 patients of both sexes, aged 20-64 yr, with body mass index of 18-30 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, scheduled for elective painless gastroscopy, were divided into 2 groups ( n=200 each) using the computer-generated random numbers: remimazolam combined with alfentanil group (group RA) and propofol combined with alfentanil group (group PA).All subjects inhaled oxygen and were denitrogenated by deep inhalation.Alfentanil 7 μg/kg and remimazolam 0.2 mg/kg were intravenously injected in group RA, and alfentanil 7 μg/kg and propofol 1.5 mg/kg were intravenously injected in group PA.When body movement occurred during operation, remimazolam 2.5 mg was intravenously injected in group RA, propofol 0.5 mg/kg was intravenously injected in group PA, and anesthesia was defined as failure when there was still body movement after 3 times of additional injection within 15 min.The success of anesthesia, effective time of sedatives, time of gastroscopy, emergence time, perioperative adverse reactions, and satisfaction score of endoscopic surgeons-anesthesiologists-patients were assessed using visual analog scale score. Results:Compared with group PA, the incidence of hypotension (6.2%/14.0%), bradycardia (6.2%/19.0%), respiratory depression (3.1%/8.0%), injection pain (2.1%/30.0%), postoperative nausea (6.3%/25.0%), fatigue (7.8%/14.0%) was significantly decreased, and the incidence of hiccup (8.3%/1.0%) and patient′ s satisfaction score were increased in group RA ( P<0.05).There was no significant difference between the two groups in the success rate of sedation, effective time of sedatives, time of gastroscopic examination, emergence time, satisfaction scores of anesthesiologists-endoscopic surgeons, and incidence of postoperative vomiting, dizziness, and lethargy ( P>0.05). Conclusions:Compared with conventional anesthesia for painless gastroscopy, remiazolam (0.2 mg/kg) combined with alfentanil (7 μg/kg) has a certain optimization effect in anesthesia for gastroscopy.
