Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will receive 0.25% levobupivacaine in a volume to be determined by the attending anaesthetist with adrenaline 5 mcg/mL and clonidine 2mcg/mL, via the caudal route, under general anaesthesia. This will be administered as a single shot caudal.

Outcomes
Primary outcome [1] 240519 0
To establish the pharmacokinetics of levobupivacaine via the caudal route, when administered with adrenaline and clonidine. We will obtain up to 6 blood samples per patient and the samples will be batch-analysed for serum levobupivacaine levels at the Biochemistry laboratory at the Royal Melbourne Hospital. NONMEM population pharmacokinetic modelling will be used to analyse this data.

Summary
Brief summary
The aim of this study is to determine how adrenaline and clonidine affect the absorption of levobupivacaine in children having caudal anaesthesia for sub-umbilical surgery. Our study hypothesis is that the absorption of levobupivacaine will be affected when administered in conjunction with adrenaline and clonidine via the caudal route.
