Wound Infiltration with Local Anesthetics Versus Transversus Abdominis Plane Block for Postoperative Pain Management in Gynecological Surgery: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Objective: Postoperative pain management significantly influences recovery speed, hospital stay duration, and healthcare costs. In light of inconsistencies in clinical trial outcomes, we conducted a systematic review and meta-analysis to assess the efficacy of the Transversus Abdominis Plane (TAP) block compared to local anesthetic wound infiltration (WI) for postoperative pain management in gynecological surgery.

Data Sources: Systematic searches were conducted across PubMed/MEDLINE, ScienceDirect, the Cochrane Library, and Web of Science databases to identify all randomized controlled trials comparing TAP block and WI in adult patients undergoing gynecological surgical procedures.

Magnetic Stirring Device for Limiting the Sedimentation of Cells inside Microfluidic Devices.

In experiments considering cell handling in microchannels, cell sedimentation in the storage container is a key problem because it affects the reproducibility of the experiments. Here, a simple and low-cost cell mixing device (CMD) is presented; the device is designed to prevent the sedimentation of cells in a syringe during their injection into a microfluidic channel. The CMD is based on a slider crank device made of 3D-printed parts that, combined with a permanent magnet, actuate a stir bar placed into the syringe containing the cells.
