Design outcomes

Primary

Measure	Time frame
To compare between 0.5ml/kg and 1.0ml/kg drug volumes of local anaesthetics for caudal analgesia on optic nerve sheath diameter in paediatric patients undergoing elective infra umbilical surgery.Timepoint: Measuring optic nerve sheath diameter before caudal block, and 1 minute, 10 minutes and 30 minutes after caudal block.	—

Secondary

Measure	Time frame
To study the changes in vital parameters using 0.5ml/kg and 1.0ml/kg drug volumes of local anaesthetics for caudal analgesia.Timepoint: Measuring the changes in vital parameters before giving caudal analgesia, and 1 minute, 10 minutes and 30 minutes after caudal analgesia.	—
