Brief Summary

Ultrasonography of optic nerve sheath diameter shows a good level of diagnostic accuracy for detecting intracranial hypertension. The aim of this study is to evaluate the effect of continuous epidural block on intracranial pressure in pediatric patients undergoing osteotomy of lower extremity. Forty patients, aged 4 years to 13 years, receiving epidural analgesia before osteotomy will be divided into bolus group (n=30) and infusion group (n=30). Randomly selected patients of the bolus group are given 0.3 ml/kg bolus/hr of 0.15% ropivacaine for epidural analgesia. In contrast, patients in the infusion group are administered 0.3 ml/kg/hr 0.15% ropivacaine at a constant rate for epidural analgesia. The primary endpoint is the difference in the optic nerve sheath diameter after epidural analgesia measured by optic nerve ultrasonography between groups.
