Ultrasound assessment of cranial spread during caudal blockade in children: Effect of different volumes of local anesthetic

Conclusion: In conclusion, the ultrasound assessment of local anesthetic spread after a caudal block showed that cranial spread of the block is dependent on the volume injected into the caudal space. Since there was no difference between 1 ml/kg and 1.25 ml/kg, to achieve a dermatomal blockade up to thoracic level, we might have to increase the dose beyond 1.25 ml/kg, keeping the toxic dose in mind.
