Enhanced analgesic efficacy and reduced stress response with ropivacaine transversus abdominis plane block in laparoscopic myomectomy.

Background: Managing postoperative pain and stress response was critical in laparoscopic myomectomy, a procedure for uterine fibroids. Ropivacaine transversus abdominis plane block (RTAPB) may offer enhanced analgesic efficacy and reduced stress responses compared to traditional analgesia.

Methods: This retrospective analysis examined 217 patients undergoing laparoscopic myomectomy at Hankou Hospital of Wuhan from June 2020 to September 2023.

Tunable Lamb wave band gaps in two-dimensional magnetoelastic phononic crystal slabs by an applied external magnetostatic field.

This paper theoretically investigates the band gaps of Lamb mode waves in two-dimensional magnetoelastic phononic crystal slabs by an applied external magnetostatic field. With the assumption of uniformly oriented magnetization, an equivalent piezomagnetic material model is used. The effects of magnetostatic field on phononic crystals are considered carefully in this model.
