Treatment of Renal Colic by Nerve Blockade with Lidocaine Versus Intravenous Dexketoprofen.
To compare non-steroidal anti-inflammatory drugs (NSAIDs) with spinal nerve blockade of related dermatomes using lidocaine for pain palliation of patients admitted to the Emergency Department (ED) with an episode of renal colic. ⋯ Spinal nerve blocks with 2% lidocaine resulted in greater short-term pain relief than intravenous dexketoprofen in ED patients with renal colic. Key Words: Renal colic, NSAID, lidocaine, Nerve blockade.

Comparative StudyFiber-Needle Swept-Source Optical Coherence Tomography for the Real-Time Visualization of the Transversus Abdominis Plane Block Procedure in a Swine Model.
Fascia blocks (eg, the transversus abdominis plane [TAP] block) target the intermuscular fascia layers. Ultrasound techniques have allowed peripheral blocks to be performed with accuracy and safety, however, with limitations. Optical coherence tomography (OCT) is based on low-coherence interferometry. In this study, we examined the ability of OCT to identify the TAP. ⋯ This study introduced a novel needle imaging probe method to identify the transversus abdominis fascia plane in real-time. Quantitative calculation of the attenuation coefficients can further aid objective identification by providing direct confirmation of the tip position, increasing the first-pass success rate, and decreasing the need for needle repositioning. Combining OCT and ultrasound may improve the accuracy of anesthetics placement.
