Randomized Controlled Trial Comparative Study
Rescuer fatigue: standard versus continuous chest-compression cardiopulmonary resuscitation.
Continuous chest-compression cardiopulmonary resuscitation (CCC-CPR) has been advocated as an alternative to standard CPR (STD-CPR). Studies have shown that CCC-CPR delivers substantially more chest compressions per minute and is easier to remember and perform than STD-CPR. One concern regarding CCC-CPR is that the rescuer may fatigue and be unable to maintain adequate compression rate or depth throughout an average emergency medical services response time. The specific aim of this study was to compare the effects of fatigue on the performance of CCC-CPR and STD-CPR on a manikin model. ⋯ CCC-CPR resulted in more adequate compressions per minute than STD-CPR for the first 2 minutes of CPR. However, the difference diminished after 3 minutes, presumably as a result of greater rescuer fatigue with CCC-CPR. Overall, CCC-CPR resulted in more total compressions per minute than STD-CPR during the entire 9 minutes of resuscitation.

Randomized Controlled Trial
Emergency department treatment of viral gastritis using intravenous ondansetron or dexamethasone in children.
To compare the efficacy of intravenous ondansetron or dexamethasone compared with intravenous fluid therapy alone in children presenting to the emergency department with refractory vomiting from viral gastritis who had failed attempts at oral hydration. ⋯ In children with dehydration secondary to vomiting from acute viral gastritis, ondansetron with intravenous rehydration improves tolerance of oral fluids after two hours and reduces the hospital admission rate when compared with intravenous rehydration with or without dexamethasone.

Randomized Controlled Trial
Digital versus local anesthesia for finger lacerations: a randomized controlled trial.
To compare the pain of needle insertion, anesthesia, and suturing in finger lacerations after local anesthesia with prior topical anesthesia with that experienced after digital anesthesia. ⋯ Digital and local anesthesia of finger lacerations with prior application of LET to all wounds results in similar pain of needle insertion, anesthetic infiltration, and pain of suturing.
