Article Abstract
Objective: To characterize penile arterial and venous blood flow in association with caudal block.
Methods: A prospective observational study was conducted in children undergoing primary circumcision at Texas Children's Hospital between September 10, 2020 and November 23, 2021. The penile artery and venous flow velocity were assessed using Doppler ultrasound pre and post caudal block under state-state anesthetic depth.
Results: Ten healthy patients were included in the study with a mean age and weight of 1.3 years and 10.7 kg, respectively. There was no significant difference in mean penile arterial blood flow velocity 0.18 m/s, (95% confidence interval: -1.55 to 1.92; P = .81) or mean dorsal penile vein flow velocity 0.11 m/s (95% confidence interval: -1.12 to 1.33; P = .84) prior to and following caudal block in our pediatric cohort. there was no correlation in the direction of change between the arterial flow and venous flow from before and after caudal block (R = 0.03).
Conclusion: We did not identify an association between penile arterial or venous blood flow and performance of a caudal block in children undergoing circumcision.

Background: The management of post-operative pain while minimizing opioid use remains challenging in thoracic surgery. While intercostal nerve blocks are commonly used, the optimal multimodal approach remains unclear.
Objectives: To evaluate whether adding hydromorphone caudal blockade to intercostal nerve blocks improves post-operative recovery outcomes in thoracic surgery patients.

Opioid stewardship efforts with non-narcotic analgesic regimens in the perioperative setting optimize outcomes. Standardized protocols for pediatric patients undergoing circumcision are lacking. To evaluate current practices, a retrospective chart review was conducted on 354 pediatric patients who underwent circumcision at a children's hospital.

The investigation aimed to reveal potential mechanisms of zinc methionine on the intestinal mucosal function of Salmonella-challenged broilers. Totally, 320 Ross 308 male chicks were divided into 4 treatments, with 8 repetition per group and 10 chicks each. A 2 × 2 factor in a randomized block design was employed to explore the impacts of zinc addition, Salmonella challenge, and their interactions.

Background And Aims: Regional anaesthesia is a component of multimodal analgesia in paediatric surgery, providing effective pain relief. Traditional techniques, such as the caudal block (CB) and, more recently, fascial plane blocks, such as the erector spinae plane block (ESPB), have gained popularity. This systematic review and meta-analysis compares CB and ESPB in paediatric surgeries involving the lower abdomen or lower limbs.

Erector spinae plane block (ESPB) and caudal epidural block (CEB) are two regional anaesthetic techniques used in paediatric surgical analgesia. While CEB is a well-established method, ESPB has gained increasing interest due to its potential for prolonged analgesia. This systematic review and meta-analysis compared the efficacy and safety of ESPB and CEB in paediatric patients undergoing surgery.
