Randomized Controlled TrialA prospective randomized trial on the role of perioperative celecoxib administration for total knee arthroplasty: improving clinical outcomes.
Total knee arthroplasty (TKA) is associated with considerable postoperative pain, which, if unrelieved, may result in prolonged hospital stay, inability to participate in rehabilitation programs, poor outcomes, and greater use of healthcare resources. The hypothesis of this study is that perioperative administration of celecoxib will improve analgesic efficacy, with a resultant improvement in short- and long-term clinical outcomes after TKA. ⋯ Perioperative use of celecoxib reduces postoperative pain, opioid consumption, opioid-related adverse effects, and is associated with long-term benefits including improved knee function and less time to achieve effective knee ROM after TKA.

Randomized Controlled TrialThe effects of intravenous granisetron on the sensory and motor blockade produced by intrathecal bupivacaine.
We hypothesized that pretreatment with i.v. granisetron would affect the sensory and motor components of spinal blockade through 5-HT(3) receptor blockade. ⋯ We concluded that i.v. granisetron facilitated a faster recovery of sensory block after bupivacaine subarachnoid anesthesia.

Randomized Controlled TrialA novel vibrotactile display to improve the performance of anesthesiologists in a simulated critical incident.
Current methods of information transfer in the operating room between monitor and anesthesiologist rely on visual and auditory modalities. These modalities can easily become overloaded in a high cognitive workload situation, such as in a critical incident. The use of vibrotactile communication has been shown to improve information transfer in other high cognitive workload environments such as aviation. We designed a novel waist-mounted vibrotactile display to be worn by the anesthesiologist to test if a vibrotactile display could improve the clinical response time to begin treating a simulated case of anaphylaxis when compared with a group using traditional information displays. In addition, we evaluated differences in situational awareness (SA) between the two groups. ⋯ Our study provides evidence that vibrotactile communication can reduce response time to critical incidents.

ReviewAntifibrinolytic therapy in surgery for congenital heart disease.
The efficacy of the serine protease inhibitor, aprotinin, and the lysine analogs, epsilon-aminocaproic acid and tranexamic acid, in reducing bleeding and transfusion in adults undergoing cardiac surgery is well established. Although children undergoing cardiac surgery are clearly at high risk for bleeding and transfusion, the risks and benefits of this therapy for the pediatric population are less well understood. There is a reasonable body of literature examining antifibrinolytic therapy in congenital heart surgery, but the large variability in patients studied, procedures, methods, and dosing schemes makes a quantitative analysis of this literature impractical. ⋯ There is not enough evidence to draw any conclusions about the safety of these drugs in children, although it appears that the risk of anaphylaxis with aprotinin in children may be less than in adults. Dosing schemes used for these drugs have been variable and not always based on sound pharmacologic principles, despite available pharmacokinetic and pharmacodynamic data. Further research should be directed toward establishing safety, evaluating the relative efficacy of the two classes of drugs, proving benefit in specific patient groups, and better defining effective dosing schemes.

Randomized Controlled TrialThe effects of oral ondansetron disintegrating tablets for prevention of at-home emesis in pediatric patients after ear-nose-throat surgery.
Tonsillectomy and adenoidectomy are associated with a frequent incidence of vomiting, both in the hospital and at home. We evaluated the effects of oral ondansetron disintegrating tablets (ODT) on the incidence of at-home emesis in children undergoing tonsillectomy with and without adenoidectomy and with and without bilateral myringotomy and tube insertion. ⋯ At-home use of ODT may prevent emesis in children during the first 3 days after tonsillectomy in children. Patients who require rescue after prophylactic treatment for nausea and vomiting in the hospital may not respond to prophylactic ondansatron ODT at home.
