Comparing the analgesic effects of ultrasound-guided caudal block and dorsal penile nerve block in pediatric concealed penis correction surgery: a randomized controlled trial.

Background: Effective perioperative analgesia is critical for pediatric patients undergoing concealed penis correction surgery. Despite the utility of regional techniques like caudal block (CB) and dorsal penile nerve block (DPNB), evidence comparing their efficacy in this population remains limited. This study aimed to compare ultrasound-guided CB and DPNB for perioperative analgesia in pediatric concealed penis surgery.

[Infraoccipital needle-knife for cervical vertigo].

Objective: To observe the clinical effect differences between infraoccipital needle-knife and massage for cervical vertigo.

Methods: A total of 366 patients with cervical vertigo were randomly assigned into a needle-knife group (186 cases) and a massage group (180 cases). With cases dropping excluded, 183 cases in the needle-knife group and 176 cases in the massage group were included.
