Observational Study
Extravasation Risk Using Ultrasound Guided Peripheral Intravenous Catheters for Computed Tomography Contrast Administration.
Ultrasound-guided intravenous catheter (USGIV) insertion is increasingly being used for administration of intravenous (IV) contrast for computed tomography (CT) scans. The goal of this investigation was to evaluate the risk of contrast extravasation among patients receiving contrast through USGIV catheters. ⋯ Patients who received contrast for a CT scan through an USGIV had a higher risk of extravasation than those who received contrast through a standard peripheral IV. Clinicians should consider this extravasation risk when weighing the risks and benefits of a contrast-enhanced CT scan in a patient with USGIV vascular access.

Review Meta Analysis
Near-infrared spectroscopy monitoring during cardiac arrest: a systematic review and meta-analysis.
Tissue oximetry using near-infrared spectroscopy (NIRS) is a noninvasive monitor of cerebral oxygenation. This new technology has been used during cardiac arrest (CA) because of its ability to give measures in low-blood-flow situations. The aim of this study was to assess the evidence regarding the association between the types of NIRS measurements (mean, initial, and highest values) and resuscitation outcomes (return of spontaneous circulation [ROSC], survival to discharge, and good neurologic outcome) in patients undergoing cardiopulmonary resuscitation. ⋯ Patients with good resuscitation outcomes have significantly higher NIRS saturations during resuscitation than their counterparts. The types of NIRS measurements during resuscitation influenced the association between ROSC and NIRS saturation. Prolonged failure to obtain a NIRS saturation higher than 30% may be included in a multimodal approach to the decision of terminating resuscitation efforts (Class IIb, Level of Evidence C-Limited Data).

Randomized Controlled Trial
Double-blind randomized controlled trial of intranasal dexmedetomidine versus intranasal midazolam as anxiolysis prior to pediatric laceration repair in the emergency department.
The objective of this study was to compare anxiolysis with intranasal dexmedetomidine, an alpha-2 agonist, versus intranasal midazolam for pediatric laceration repairs. ⋯ Intranasal dexmedetomidine is an alternative anxiolytic medication to intranasal midazolam for pediatric laceration repairs, performing similarly in our study, except that patients who received dexmedetomidine had less anxiety at the time of positioning for procedure.

The objective was to compare video-assisted laryngoscopy (VAL) to direct laryngoscopy (DL) on success rate and complication rate of intubations performed in a pediatric emergency department (ED). ⋯ We found no difference between DL and VAL with regard to first-pass intubation success rate, complication rate, or rate of successful intubation by ED providers for children undergoing intubation in a pediatric ED.

Multicenter Study Observational Study
Performance of the Pediatric Glasgow Coma Scale Score in the Evaluation of Children with Blunt Head Trauma.
The objective was to compare the accuracy of the pediatric Glasgow Coma Scale (GCS) score in preverbal children to the standard GCS score in older children for identifying those with traumatic brain injuries (TBIs) after blunt head trauma. ⋯ The pediatric GCS for preverbal children was somewhat less accurate than the standard GCS for older children in identifying those with TBI on CT. However, the pediatric GCS for preverbal children and the standard GCS for older children were equally accurate for identifying ciTBI.
