Randomized Controlled Trial Comparative Study Clinical TrialAnalgesia for circumcision in a paediatric population: comparison of caudal bupivacaine alone with bupivacaine plus two doses of clonidine.
Clonidine is often used to improve the duration and quality of analgesia produced by caudal epidural blockade, although the optimum dose of clonidine with bupivacaine remains uncertain. ⋯ For paediatric circumcision, under general anaesthesia, the addition of clonidine 2 microg x kg(-1) to low volume (0.5 ml x kg(-1)) caudal anaesthetics has a limited clinical benefit for children undergoing circumcision.

Randomized Controlled Trial Comparative Study Clinical TrialDownfolding of the epiglottis induced by the laryngeal mask airway in children: a comparison between two insertion techniques.
The purpose of this study was to compare the incidence of the downfolding of the epiglottis in children during insertion of the laryngeal mask airway (LMATM) using the standard technique and an alternative technique with the cuff partially inflated. ⋯ The partially inflated cuff insertion technique does not increase the incidence of the downfolding of the epiglottis in children and would be an acceptable alternative to the standard technique.

Randomized Controlled Trial Comparative Study Clinical TrialPressure versus volume-controlled ventilation with a laryngeal mask airway in paediatric patients.
The utility of positive pressure ventilation with the laryngeal mask airway (LMA) in children was described previously, but the possibility of gastric insufflation, related to high peak airway pressure, continues to be a disadvantage. In this prospective study, inspiratory pressures, air leak and signs of gastric insufflation were compared between volume-controlled ventilation (VCV) and pressure-controlled ventilation (PCV) using an LMA. ⋯ During general anaesthesia in children using an LMA, PCV offers lower peak inspiratory airway pressures while maintaining equal ventilation compared with VCV. Although no signs of gastric insufflation were detected in both groups, the lower pressures might be significant in patients with reduced chest wall or lung compliance.

Randomized Controlled Trial Comparative Study Clinical TrialHow to prolong postoperative analgesia after caudal anaesthesia with ropivacaine in children: S-ketamine versus clonidine.
The aim of the study was to determine whether caudal S-ketamine or clonidine prolonged analgesia together with ropivacaine. ⋯ This study demonstrates that S-ketamine 0.5 mg x kg(-1) when added to 0.2% caudal ropivacaine provides better postoperative analgesia than clonidine without any clinically significant side-effect.

Case ReportsLife threatening cardiopulmonary failure in an infant following protamine reversal of heparin after cardiopulmonary bypass.
Life threatening cardiopulmonary failure following protamine reversal of heparin after cardiopulmonary bypass (CPB) was reported to occur in adults but rarely in children. Atrial septal defect closure was performed in a 6-week-old infant erroneously suspected to suffer from right atrial thrombosis in addition. ⋯ Inhaled nitric oxide, together with high frequency oscillation ventilation supplemented by intravenous prostacycline, enabled complete recovery of cardiopulmonary and neurological function. Life threatening cardiovascular compromise after intravenous protamine can occur even in young infants which then require challenging paediatric critical care.
