Comparative StudyAccuracy and consistency of modern elastomeric pumps.
Continuous peripheral nerve blockade has become a popular method of achieving postoperative analgesia for many surgical procedures. The safety and reliability of infusion pumps are dependent on their flow rate accuracy and consistency. ⋯ Several studies have investigated the accuracy of portable infusion pumps. Using methodology similar to that used by Ilfeld et al, we investigated the accuracy and consistency of several current elastomeric pumps.

Randomized Controlled TrialPreoperative Fascia Iliaca Compartment Block for Positioning Patients With Hip Fractures for Central Nervous Blockade: A Randomized Trial.
Appropriate pain management may positively affect outcome following hip fractures. Positioning patients for spinal anesthesia (SA) can be extremely painful. Peripheral nerve blockades are gaining popularity in this setting. This prospective, randomized study compares the efficacy of fascia iliaca compartment block (FICB) to intravenous (IV) fentanyl for positioning hip fracture patients for SA. ⋯ Performing an FICB before positioning for SA provides superior pain management compared with IVFE administration, facilitates spinal performance, and yields satisfactory postoperative analgesia and wide patient acceptance, hence improving overall quality and efficiency of care.

Observational StudyThe Incidence of Hematoma Formation in Patients With Continuous Femoral Catheters Following Total Knee Arthroplasty While Receiving Rivaroxaban as Thromboprophylaxis: An Observational Study.
Multimodal analgesia, including continuous femoral block, is often used to manage postoperative pain following total knee arthroplasty. To reduce the risk of deep vein thrombosis and pulmonary embolus formation, anticoagulation is also a part of the care for patients who undergo total knee arthroplasty. However, the concurrent use of continuous peripheral nerve block and anticoagulation can lead to hematoma formation. This prospective, single-center, observational study investigated the incidence of hematoma formation, causing neurovascular compromise, for patients with femoral catheters while taking the oral anticoagulant rivaroxaban. ⋯ In this prospective observational study, the concurrent administration of continuous femoral nerve block, the once-daily administration of the anticoagulant rivaroxaban, and the timed removal of the femoral catheter were not associated with hematoma formation resulting in neurovascular compromise at the femoral catheter insertion site or groin area.

Development of an Ultrasound Phantom for Spinal Injections With 3-Dimensional Printing.
This report describes a method for producing anatomically detailed, low-cost ultrasound phantoms of the spine with 3-dimensional printing. An implementation that involves representing a portion of the lumbar spine and the ligamentum flavum with 2 different printing materials and the surrounding soft tissues with agar gel is presented. ⋯ Ultrasound phantoms that are derived directly from patient anatomy have strong potential as learning tools for ultrasound-guided spinal insertions, and they could be used as preprocedural planning tools in cases involving pathologies, implants, or abnormal anatomies. Three-dimensional printing is a promising method for producing low-cost phantoms with designs that can be readily shared across clinical institutions.
