Randomized Controlled Trial Comparative Study
Randomized controlled trial of single-operator vs. two-operator ultrasound guidance for internal jugular central venous cannulation.
Use of ultrasound guidance for central line placement generally requires two operators: one to hold the transducer and the other to guide the needle. The authors propose a single-operator technique and compare it with the two-operator technique for placement of internal jugular central lines. ⋯ This one-person technique appears to be equivalent to the standard two-person technique for successful ultrasound-guided internal jugular central venous catheterization with respect to overall success.

Randomized Controlled Trial Comparative Study
The decision to use topical anesthetic for intravenous insertion in the pediatric emergency department.
Topical anesthetic creams to reduce the pain of intravenous (IV) placement may be more effectively used in the emergency setting if they are applied by nurses in the triage area of the emergency department or soon after the patient is placed into a room. This strategy requires accurate prediction of which patients will require IV placement. The objective of this study was to compare triage nurse judgment regarding IV placement in pediatric patients with a triage prediction rule using chief complaint, referral status, and high-risk medical history. A secondary objective was to evaluate whether the presence of the anesthetic cream placed in triage influenced the subsequent decision to place an IV and thus invalidate the prediction strategy. ⋯ Triage nurse judgment to predict eventual IV placement had greater sensitivity and similar predictive value compared with a prediction model based on medical history and chief complaint. The triage placement of topical anesthetic in pediatric patients did not change the eventual rate of IV placement.
