Randomized Controlled Trial Comparative Study Clinical TrialThe effect of ketamine on 0.25% and 0.125% bupivacaine for caudal epidural blockade in children.
Forty boys aged from one to five years undergoing orchidopexy were randomly allocated to receive one of two solutions for caudal epidural injection. Group A received 1 ml.kg-1 of 0.125% bupivacaine with ketamine 0.5 mg.kg-1 and Group B received 1 ml.kg-1 of bupivacaine 0.25% with ketamine 0.5 mg.kg-1. ⋯ The time taken to recover the ability to walk was a median of two h in Group A and three h in Group B (P<0.05). There were no differences between the groups in the incidence of urinary retention or postoperative sedation.

Randomized Controlled Trial Comparative Study Clinical TrialRopivacaine 0.25% compared with bupivacaine 0.25% by the caudal route.
We compared in a randomized double-blind study, the postoperative analgesia and degree of motor block produced by the new local anaesthetic ropivacaine, with bupivacaine, for caudal anaesthesia in children. Eighty children, 2-5-years-old, ASA I, received one of two local anaesthetics; either ropivacaine 0.25% (1.0 ml x kg(-1)) or bupivacaine 0.25% (1.0 ml x kg(-1)). They were sedated with a continuous infusion of propofol (200 microg x kg(-1) min(-1). ⋯ The ropivacaine group showed a shorter duration of motor block than the bupivacaine group (P<0.05). The first postoperative analgesic requirement was a mean (sd) of 5 h+/-4.32 after the operation in the ropivacaine group and 5 h+/-3.81 for the bupivacaine group. These findings suggest that caudal anaesthesia with ropivacaine 0.25% in paediatric patients can be effective, with less motor blockade in the postoperative period.

Randomized Controlled Trial Clinical TrialPrevention of postoperative vomiting with granisetron in paediatric patients with and without a history of motion sickness.
A history of motion sickness is one of the patient-related factors associated with postoperative emesis. This prospective, randomized, double-blind, placebo-controlled study was undertaken to assess the efficacy of granisetron, a selective 5-hydroxytryptamine type 3 receptor antagonist, for preventing postoperative vomiting after tonsillectomy in 120 children with (n = 60) and without (n = 60) a history of motion sickness. ⋯ No clinically serious adverse effects due to the study drug were observed in any of the groups. In conclusion, prophylactic antiemetic therapy with granisetron is effective for preventing postoperative emesis in children with a history of motion sickness as well as in those without it.

Randomized Controlled Trial Clinical TrialLaryngeal mask airway use in children with acute burns: intraoperative airway management.
Paediatric patients with acute burns often require many operative procedures in short succession; yet due to inhalation injury or recent extubation their airways may be susceptible to tracheal tube induced damage. We proposed the laryngeal mask airway (LMA) as a useful airway management tool in this setting. In this prospective study, 80 eight (88) patients with mean age (+/- SD) of 7.8 +/- 4.7 years and average percentage total body surface area burned (%TBSA) of 21 +/- 18% had their airways managed with an LMA while in the operating room for 141 procedures. ⋯ The other 10 events include arterial desaturation (n = 3), partial laryngospasm (5), airway obstruction (1) and regurgitation without aspiration (1). In each case, corrective action led to resolution of the problem with no patient morbidity. This series demonstrates the LMA is a safe and efficacious airway management device in the paediatric burn population.

ReviewAnaesthetic implications of thoracoscopic surgery in children.
As the equipment and technique have improved, minimally invasive surgery is being applied to younger and younger children. With the advent of this valuable surgical technique, there are also specific modifications necessary in the anaesthetic technique. ⋯ The following article attempts to address and review the specific anaesthetic implications of thoracoscopic procedures in neonates, infants, and children including the preoperative evaluation, intraoperative care and monitoring, and postoperative issues including analgesia. The techniques of one-lung anaesthesia, commonly required for thoracoscopy, are reviewed as well as consideration of the adverse effects which can occur during thoracoscopy including inadvertent intravascular CO2 embolism.
