About

Ultrasound (US) has facilitated the use of caudal block in children and visualization of the needle during insertion. This prospective clinical trial study compares between two different sizes of the used needles, in terms of success rate, number of punctures, detection of the US signs (visualization of the needle, dural displacement, turbulence, and distention), and complications in pediatrics aging between 6-36 months requiring elective lower abdominal and perineal surgeries.

Full description

Ultrasound (US) has facilitated the use of caudal block in children, allowing an initial assessment of the anatomy of the sacrum, including the relationship of the sacral hiatus to the dural sac ending. Real-time US allows visualization of the needle during insertion to reach the dural sac, and to see the turbulence and distention of the layers during injection of the local anesthetic drug.

This prospective clinical trial study compares between two different sizes of the used needles, in terms of success rate, number of punctures, detection of the US signs (visualization of the needle, dural displacement, turbulence, and distention), and complications in pediatrics aging between 6-36 months requiring elective lower abdominal and perineal surgeries.

---

100 participants in 2 patient groups

group C

Experimental group

Description:

After induction of general anesthesia, patients will undergo caudal block by classical Gauge 22 needle under ultrasound guidance using a linear probe 5.5-12 MHz, and Bupivacaine 1 ml/kg of 0.25% will be injected.

Treatment:

Device: The use of classical Gauge 22 needle

Group S

Experimental group

Description:

After induction of general anesthesia, patients will undergo caudal block by Gauge 27 needle under ultrasound guidance using a linear probe 5.5-12 MHz, and Bupivacaine 1 ml/kg of 0.25% will be injected.

Treatment:

Device: The use of classical Gauge 27 needle
