After obtaining the approval of ethical committee and parental written informed consent, a total of 70 children undergoing elective lower abdominal surgeries under caudal epidural anaesthesia were included in the study. After having met inclusion and exclusion criteria, patients were randomized based on computer generated randomization table into one of the two groups.  Group A: Caudal block by traditional method and whoosh test.  Group B: Caudal block using ultrasound. A thorough pre-anaesthetic evaluation was done. Detailed medical and personal history was obtained. A detailed physical examination was done. In the present study we found no statistically significant difference between group A and group B with regards to mean age (33.49±22.61 and 37.71±23.63 months respectively; p = 0.44), mean weight (11.31±3.97 and 11.74±3.48 kgs respectively; p = 0.63). In the present study, only 4 patients in group A had increase in heart rate of >15% from baseline value while none in group B and was statistically nonsignificant (p<0.122).
