Clinical Trials

  • Multicenter Perioperative Opioid Pharmacogenetic Study Not Recruiting

    The purpose of this research study is to identify factors and genes (the DNA material that determines the makeup of the human body) that may be associated with how children respond to pain medication. Specifically, the investigators want to study factors that may be associated with pain sensitivity, morphine requirement after surgery and side-effects from morphine and other pain medications. The investigators expect that the information obtained in this research study will help us to develop more effective, safe, and tailored treatment options in the future.

    Stanford is currently not accepting patients for this trial. For more information, please contact R J Ramamurthi, (650) 776 - 6297.

    We report the use of dexmedetomidine for laryngoscopy, rigid bronchoscopy, and tracheal extubation in the operating room in two children who had undergone tracheal reconstruction 1 week previously. Dexmedetomidine in combination with propofol provided appropriately deep anesthesia during these brief but stimulating procedures without cardiovascular or respiratory depression.

  • Clonidine for the prevention of emergence agitation in young children: efficacy and recovery profile PEDIATRIC ANESTHESIA Malviya, S., Voepel-Lewis, T., Ramamurthi, R. J., Burke, C., Tait, A. R. 2006; 16 (5): 554-559


    Emergence agitation (EA) is a common postoperative problem in young children who have received sevoflurane and isoflurane for general anesthesia. This randomized, double-blinded study evaluated the efficacy of intraoperative clonidine in reducing EA, and describes its recovery profile.With Institutional Review Board approval and informed consent, children undergoing brief, minimally painful procedures were studied. All children received preemptive analgesia with acetaminophen and ketorolac, sevoflurane for induction, and isoflurane for maintenance of anesthesia. Children received either 2 clonidine or placebo intravenously (i.v.) following induction of anesthesia. Children were observed postoperatively for behavior and side effects, and their parents were telephoned the next day to determine postdischarge recovery characteristics.One hundred and twenty children were included in this study: 59 of whom received clonidine, and 61 placebo; 41% of those in the placebo group exhibited moderate-severe EA compared with only 22% of those in the clonidine group (P < 0.03). Compared with those who received placebo, children who received clonidine awakened more slowly (22 min vs 14 min), had a longer postanesthesia care unit stay (57 min vs 46 min), and experienced sleepiness more frequently after discharge (75% vs 39%; all comparisons significant at P < 0.03). There were no adverse cardiorespiratory events in either group.Findings demonstrate that i.v. clonidine administered after induction of anesthesia significantly reduces the incidence of EA in young children, but is associated with sleepiness postoperatively.
