Study summary

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.

Read the detailed 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.

Study arms

  • Experimental
    group C

    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.

What researchers measure

Primary outcomes

  1. Opioids requirements intraoperatively

    The investigators will document the required dose of opioids intraoperatively

    Time frame: 90 minutes

  2. Pain score in the post-anesthesia care unit (PACU)

    Pain score will be assessed regularly during the stay in the PACU using a pain scoring scale, where the score is interpreted from 0 to 10, in which 0 means no pain and 10 signifies very severe pain.

    Time frame: 120 minutes

  3. Peri-operative complications

    Peri-operative complications related to the caudal block procedure will be documented from the start of the procedure till the discharge from the post-anesthesia care unit.

    Time frame: 210 minutes
