Objective: To explore the effect and complications of esketamine combined with ultrasound-guided nerve block in children with lower extremity fractures.
Methods: 120 children with fractures of lower extremities were included into the observation group (OG) and control group (CG) according to the specific anesthesia method. The OG was given esketamine combined with ultrasound-guided nerve block, and the CG was given ultrasound-guided nerve block combined with general anesthesia. Serum norepinephrine (NE), epinephrine (E), renin (R), mean arterial pressure (MAP), heart rate (HR), oxyhemoglobin saturation (SpO) and respiration rate (RR) were measured before, at 10, 20, and 30 min after anesthesia. The incidence of clinical complications and the anesthetic effects were compared between the two groups. The mini-mental state examination (MMES) scale was performed to evaluate the cognitive function of children in the two groups before and after surgery.
Results: At 10 min and 20 min after anesthesia, the CG showed higher MAP and HR than the OG (<0.05); however, RR and SpO showed no difference between the two groups (>0.05). At 30 min after anesthesia, HR and MAP were not significantly different between the two groups (>0.05); NE, E, and R showed no significant difference before surgery (>0.05), which were higher in CG than those in the OG after surgery (<0.05). The success rate of nerve block and anesthesia were 91.67% and 85.00%, respectively in the OG, which were higher than 88.33% and 83.33% in the CG (>0.05). The OG had a complication rate of 8.33%, significantly lower than that of 20.00% in the CG (<0.05).
Conclusion: Esketamine combined with ultrasound-guided nerve block anesthesia was superior to ultrasound-guided nerve block combined with general anesthesia in children with lower extremity fractures, with fewer compilations.

Purpose: To evaluate the feasibility, safety, and short-term (3-month) results of transperineal prostate thermal ablation (TPTA) as a minimally invasive outpatient treatment for benign prostatic hyperplasia (BPH).
Materials And Methods: A prospective nonrandomized study of 25 patients with lower urinary tract symptoms secondary to BPH seeking care at 2 interventional radiology centers between March and July 2024. TPTA was performed using a 17G radiofrequency needle with a 10-mm active tip under unconscious sedation combined with bilateral perineal and periprostatic nerve blocks.
A 78-year-old woman with a prosthetic hip dislocation underwent a pericapsular nerve group block for regional anesthesia. The hip spontaneously reduced before manual intervention, likely due to the block's analgesic and muscle-relaxing effects. Compared to other techniques, this block effectively targets hip innervation while sparing motor function.

Background: Postoperative pain remains a significant problem in patients undergoing donor nephrectomy despite reduced tissue trauma following laparoscopic living donor nephrectomy (LLDN). Inadequately treated pain leads to physiological and psychological consequences, including chronic neuropathic pain.
Materials And Methods: This randomized controlled double-blinded trial was conducted in sixty-nine (n = 69) participants who underwent LLDN under general anesthesia.

Background/importance: Local anesthetic (LA) mixtures are used in peripheral nerve blocks (PNB) to improve onset, though study results remain conflicting.
Objective: This systematic review and meta-analysis compared the efficacy outcomes of long-acting LA to their mixture with shorter-acting LA in ultrasound-guided PNB. The primary outcome was sensory block onset.

Objective: To evaluate the clinical efficacy of ultrasound-guided needle knife release with different pathways for carpal tunnel syndrome (CTS).
Methods: Sixty CTS patients were randomly divided into a transverse group and a longitudinal group, with 30 patients in each group. The transverse group received the needle knife release under ultrasound above and below the median nerve along the short axis, while the longitudinal group received the needle knife release under ultrasound above the median nerve along the long axis.
