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 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.

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.

Randomized Controlled TrialA comparison of the end-tidal sevoflurane concentration for removal of the laryngeal mask airway and laryngeal tube in anesthetized children.
In this study we quantified and compared the optimal sevoflurane concentration required to prevent coughing or moving during or after removal of the laryngeal mask airway (LMA) and the laryngeal tube (LT) in anesthetized children. ⋯ LMA and LT removal in 95% of anesthetized children (aged 8 mo to 12 yr) can be safely accomplished without coughing, moving, or any other airway complications at 0.86 and 0.80 minimum alveolar anesthetic concentration, respectively, and a similar concentration should be used for removal of the LT or LMA in children.

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.
