ABSTRACT
We describe the case of a 3-year-old boy with a subtotal amputation of the right foot who received treatment for pain via a peripheral catheter positioned at the level of the sciatic nerve (lateral approach).We administered a continuous infusion of 0.2% ropivacaine, 0.4 mg x kg(-1) x h(-1) plus clonidine 0.12 microg x kg(-1) x h(-1) for 21 days. Pain relief was complete and the patient did not require any further rescue analgesia throughout the period even during medications and surgical treatment in our intensive care unit. We discuss the safety and efficacy of the use of a peripheral continuous infusion in children compared with other techniques of analgesia.

UNLABELLED: We investigated three different concentrations of levobupivacaine (0.125%, 0.20%, and 0.25%; n = 20 in each group) for caudal blockade in a prospective, randomized, observer-blinded fashion in children (1-7 yr) undergoing subumbilical surgery. The duration of postoperative analgesia was assessed as the time to first administration of supplemental analgesia (based on a Childrens and Infants Postoperative Pain Scale score of >or=4), and the degree of immediate postoperative motor blockade was determined by use of a 3-point scale. A dose-response relationship was observed both with regard to median duration of postoperative analgesia (0.125%, 60 min; 0.20%, 118 min; 0.25%, 158 min) and the number of patients with evidence of early postoperative motor blockade (0.125%, 0; 0.20%, 4; 0.25%, 8). The 0.125% concentration was associated with significantly less early motor blockade (P = 0.003) but was found to result in a significantly shorter duration of postoperative analgesia (P < 0.05). Based on these results, the use of 0.20% levobupivacaine might represent the best clinical option if a plain levobupivacaine solution is to be used for caudal blockade in children. IMPLICATIONS: The use of 0.125% levobupivacaine for caudal blockade (1 mL/kg) in children (1-7 yr) was associated with less early postoperative motor blockade but a shorter duration of postoperative analgesia compared with 0.20% and 0.25% solutions.
