Randomized Controlled Trial
Head position angles to open the upper airway differ less with the head positioned on a support.
The aim of the study was to assess the effects of positioning the head on a support on "head position angles" to optimally open the upper airway during bag-valve mask ventilation. ⋯ In the head-with-a-support group, when compared with the head-without-a-support group, head position angles differed less, indicating a decreased potential for failure during bag-valve mask ventilation with the head on a support. Moreover, in the head-with-a-support group, ventilation parameters differed less between head positions, and ventilation improved. These findings suggest a potential benefit of positioning the head on a support during bag-valve mask ventilation.

Randomized Controlled Trial
Isolated sternal fractures treated on an outpatient basis.
The aim of this study is to investigate the need for admission of patients with isolated sternal fracture (ISF) by prospectively and randomly discharging or admitting them. ⋯ Patients with ISF can be discharged safely as soon as investigations are completed. Extensive myocardial assessment is not needed on the posttraumatic period. Myocardial involvement seems unlikely in patients with ISF, who can be treated with oral analgesics.

Randomized Controlled Trial Comparative Study
Comparison of ketamine-low-dose midozolam with midazolam-fentanyl for orthopedic emergencies: a double-blind randomized trial.
Most of the fractures and dislocations are reduced in the emergency setting. Many drugs are available for procedural sedation and analgesia in the emergency department (ED); however, the adverse effects are still a common problem. The aim of our study was to compare the 2 drug combinations. ⋯ Both drug combinations can be effectively used for procedural sedation and analgesia; however, with lower risk for hypoxia and lower pain scores, KM combination stands as a reasonable choice for orthopedic interventions in the emergency unit.

Randomized Controlled Trial
A randomized, controlled trial to evaluate topical anesthetic for 15 minutes before venipuncture in pediatrics.
The aim of the study was to assess the differences in reported pain from venipuncture comparing liposomal 4% lidocaine with placebo cream in a pediatric population. Other factors assessed were patient anxiety, difficulty of venipuncture, and history of venipuncture. ⋯ Topical liposomal 4% lidocaine cream in this case did not prove to be effective with a 15-minute dwell time under occlusion because there were no differences in pain between study groups.

Randomized Controlled Trial Comparative Study
Optimal external laryngeal manipulation: modified bimanual laryngoscopy.
External laryngeal manipulation (ELM) is commonly used to facilitate laryngeal view during direct laryngoscopy. We evaluated the effectiveness of the newly modified bimanual laryngoscopy, which involves a direct guidance of an assistant's hand by a laryngoscopist, to optimize laryngeal exposure during direct laryngoscopy compared with conventional bimanual laryngoscopy. ⋯ The modified bimanual laryngoscopy is more effective for obtaining the optimal laryngeal view on the first attempt compared with the conventional bimanual laryngoscopy.
