Randomized Controlled Trial Observational Study
Comparison of the perfusion index as an index of noxious stimulation in monitored anesthesia care of propofol/remifentanil and propofol/dexmedetomidine: a prospective, randomized, case-control, observational study.
Dexmedetomidine, one of the sedatives, has an analgesic effect. We aimed to investigate postoperative analgesia with dexmedetomidine as adjuvants for procedural sedation using perfusion index (PI). ⋯ We could not find a significant correlation between PI and NRS score for postoperative pain control. Using PI as a single indicator of pain is insufficient.

Randomized Controlled TrialEffect of lidocaine or dexmedetomidine on postoperative recovery in elder patients undergoing colorectal surgery.
Opioid sparing techniques have been shown to promote gastrointestinal recovery, shorten length of stay (LOS), and reduce opioid-related complications. We investigated whether intraoperative intravenous lidocaine or dexmedetomidine infusion could improve gastrointestinal recovery in elderly patients undergoing laparoscopic colorectal surgery. ⋯ Intraoperative intravenous lidocaine infusion accelerated return of the bowel function in elderly patients undergoing elective colorectal surgery.

Randomized Controlled Trial
A randomised controlled trial of dexmedetomidine for delirium in adults undergoing heart valve surgery.
Dexmedetomidine might reduce delirium after cardiac surgery. We allocated 326 participants to an infusion of dexmedetomidine at a rate of 0.6 μg kg-1 for 10 min and then at 0.4 μg.kg-1 .h-1 until the end of surgery; 326 control participants received comparable volumes of saline. ⋯ Postoperative renal impairment (Kidney Disease Improving Global Outcomes stages 1, 2 and 3) was detected in 46, 9 and 2 participants after dexmedetomidine and 25, 7 and 4 control participants, p = 0.040. Intra-operative dexmedetomidine infusion did not reduce the incidence of delirium after cardiac valve surgery but might impair renal function.

Randomized Controlled Trial
Dexmedetomidine improves lung compliance in patients undergoing lateral decubitus position of shoulder arthroscopy: A randomized controlled trial.
The improvement of oxygenation and pulmonary mechanics in patients under general anesthesia can be achieved by dexmedetomidine (DEX) infusion. However, its role in patients undergoing lateral supine shoulder arthroscopy has not been thoroughly studied. This study aimed to evaluate the effect of DEX on lung compliance in patients undergoing shoulder arthroscopic surgery in a lateral decubitus position. ⋯ DEX can improve lung compliance and reduce airway pressure and platform pressure of patients undergoing shoulder arthroscopy in the lateral position under general anesthesia.

Randomized Controlled TrialDexmedetomidine and Propofol Sedation in Critically Ill Patients and Dose Associated 90-day Mortality: A Secondary Cohort Analysis of a Randomized Controlled Trial (SPICE-III).
Rationale: The SPICE III (Sedation Practice in Intensive Care Evaluation) trial reported significant heterogeneity in mortality with dexmedetomidine treatment. Supplemental propofol was commonly used to achieve desirable sedation. Objectives: To quantify the association of different infusion rates of dexmedetomidine and propofol, given in combination, with mortality and to determine if this is modified by age. ⋯ Conclusions: In patients ⩽65 years of age sedated with dexmedetomidine and propofol combination, preferentially increasing the dose of propofol was associated with decreased adjusted 90-day mortality. Conversely, increasing dexmedetomidine may be associated with increased mortality. Clinical trial registered with www.clinicaltrials.gov (NCT01728558).
