Randomized Controlled Trial Comparative Study Clinical TrialCaudal anesthesia for minor pediatric surgery: a prospective randomized comparison of ropivacaine 0.2% vs levobupivacaine 0.2%.
Previous published data comparing ropivacaine 0.2% with levobupivacaine 0.25% have suggested that ropivacaine might be associated with less early postoperative motor blockade compared with levobupivacaine. The aim of the present study was to further investigate this issue comparing equal concentrations (0.2%) of ropivacaine and levobupivacaine in children undergoing minor subumbilical surgery. ⋯ A 0.2% concentrations of ropivacaine or levobupivacaine are clinically very similar with regard to postoperative analgesia and unwanted postoperative motor blockade in children undergoing minor subumbilical surgery.

Randomized Controlled Trial Clinical TrialIntraoperative low-dose S-ketamine has no preventive effects on postoperative pain and morphine consumption after major urological surgery in children.
Clinical studies suggest low-dose ketamine may have preemptive effects on postoperative pain in adults. The objective of this study was to determine whether intraoperative low-dose S-ketamine reduces postoperative pain and morphine consumption in children undergoing major urological surgery. ⋯ Intraoperative low-dose S-ketamine had no effect on morphine consumption during the first 72 h after surgery. The differences in pain intensity and time to first PCA use probably reflect additional sedation and antinociceptive effects of S-ketamine rather than a true 'prevention' of pain.

Randomized Controlled Trial Clinical TrialThe addition of clonidine 2 microg.kg-1 does not enhance the postoperative analgesia of a caudal block using 0.125% bupivacaine and epinephrine 1:200,000 in children: a prospective, double-blind, randomized study.
In this prospective, randomized, double-blind study, we compared the efficacy of 0.125% bupivacaine and epinephrine 1:200,000 with and without clonidine 2 microg.kg-1 for 'single shot' pediatric caudal analgesia. ⋯ We found that the addition of clonidine 2 microg.kg-1 to 0.125% bupivacaine with fresh epinephrine 1:200,000 for caudal analgesia did not significantly delay the time to first rescue analgesic or decrease the overall need for rescue analgesics in children 2-8 years undergoing surgical procedures below the umbilicus.

Randomized Controlled Trial Comparative Study Clinical TrialSevoflurane (12% and 8%) inhalational induction in children.
Sevoflurane induction of anesthesia is frequently used in children. Rapidly performed inhalational induction may reduce excitation during early anesthesia. Increasing the total anesthetic MAC delivered to patients can be achieved by increasing volatile concentration or adding nitrous oxide. The latter reduces inspired oxygen concentration delivered, which may not be desirable. Even 8% sevoflurane induction is associated with excitation. A system capable of delivering 12% sevoflurane using two tandem vaporizers has been developed. ⋯ Twelve percent sevoflurane offers a smoother anesthesia induction than 8% in children of this age with no additional consequences for the cardiovascular system.
