Key result
Perfusion index and heart rate variations assessed to determine successful caudal block onset in children.
Why the study?
Caudal blocks are commonly used to reduce intraoperative anaesthetic and analgesic dosages in children, but the efficacy of perfusion index and heart rate variations in predicting block onset and success needed investigation.

Perfusion index vs heart rate variations
Perfusion index may aid pediatric caudal block assessment; hypothesis-generating and requires validation before practice change.
Background To reduce the dosages of the intraoperative anaesthetic and analgesic agents, the caudal block is most frequently used in children. The work aims to investigate the efficacy of perfusion index (PI) and heart rate (HR) variations following the caudal block in determining the onset and appropriateness of the caudal block in children.
