Clinical Scorecard: Impact of Injection Velocity on the Temporal Changes of Optic Nerve Sheath Diameter During Caudal Block in Pediatric Patients: A Prospective Randomized Study
At a Glance
Category
Detail
Condition
Key Mechanisms
Injection speed influences ONSD dynamics during caudal block.
Target Population
Care Setting
Key Highlights
High-speed injection (1 mL/s) resulted in higher ONSD immediately after injection compared to low-speed (0.1 mL/s).
Low-speed injection produced a more gradual rise in ONSD over time.
Both injection speeds were well tolerated with no adverse events reported.
Guideline-Based Recommendations
Diagnosis
Monitor ONSD as a reflection of transient intracranial pressure changes during caudal block.
Management
Monitoring & Follow-up
Regularly measure ONSD at baseline, immediately after injection, and at 10, 20, and 40 minutes post-injection.
Risks
Transient elevation of intracranial pressure indicated by increased ONSD.
Patient & Prescribing Data
Children aged 1–3 years, ASA physical status I–II.
0.2% ropivacaine at 0.5 mL/kg is used for caudal block.
