abstract = {Background: This study aimed to investigate the effects of dexmedetomidine on the post-operative recovery and mental status in patients receiving robotic-assisted thoracic surgery (RATS).
Methods: One hundred patients who received selective RATS under general anesthesia were recruited and assigned into control group (C) and dexmedetomidine group (D). The anesthesia induction and maintenance were consistent between groups. Midazolam, sufentanil, propofol and rocuronium were intravenously injected for anesthesia induction, followed by mechanical ventilation after endotracheal intubation. Sevoflurane inhalation at a minimum alveolar concentration (MAC) of 0.5 was administered, propofol and remifentanil were intravenously injected to maintain the bispectral index (BIS) at 40–60, and rocuronium was intravenously injected once every 30 min. In the D group, dexmedetomidine was intravenously injected after endotracheal intubation, and then it was injected before the end of surgery. In the C group, normal saline of equal volume was injected. The hemodynamic parameters, blood loss, urine volume, time of surgery, time of anesthesia, total dose of propofol, time of thoracic tube indwelling, hospital stay and pulmonary complications were recorded; blood gas analysis was performed after extubation; the QoR-15 and mini-mental state examination (MMSE) questionnaires were employed for the assessment of mental status at 1 and 3 days after surgery.
Results: The mean arterial pressure (MAP), heart rate (HR) and brain oxygenation were similar between groups at different time points (P>0.05). There were no significant differences in the operation time, time of anesthesia and intra-operative urine volume between groups. As compared to the C group, the blood loss and dose of propofol reduced significantly (P},
