Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
low dose group
Patients in the low dose group are given 1.0 ml/kg of 0.15% ropivacaine for caudal block.
1.0 ml/kg of 0.15% ropivacaine
Randomly selected patients of the high dose group are given 1.5 ml/kg of 0.15% ropivacaine for caudal block before their surgery. In contrast, patients in the low dose group are given 1.0 ml/kg of 0.15% ropivacaine for caudal block before surgery.
high dose group
Patients in the high dose group are given 1.5 ml/kg of 0.15% ropivacaine for caudal block.
1.5 ml/kg of 0.15% ropivacaine
Randomly selected patients of the high dose group are given 1.5 ml/kg of 0.15% ropivacaine for caudal block before their surgery. In contrast, patients in the low dose group are given 1.0 ml/kg of 0.15% ropivacaine for caudal block before surgery.
