Randomized Controlled Trial
Analgesic efficacy of caudal dexamethasone combined with ropivacaine in children undergoing orchiopexy.
Epidural administration of dexamethasone might reduce postoperative pain in adults. We evaluated whether a caudal block of 0.1 mg kg(-1) dexamethasone combined with ropivacaine improves analgesic efficacy in children undergoing day-case orchiopexy. ⋯ The addition of dexamethasone 0.1 mg kg(-1) to ropivacaine for caudal block can significantly improve analgesic efficacy in children undergoing orchiopexy. Clinical trial registration NCT01604915.

Randomized Controlled Trial
Reduced local immune response with continuous positive airway pressure during one-lung ventilation for oesophagectomy.
Transthoracic oesophagectomy requires prolonged one-lung ventilation causing systemic and local inflammatory responses. Application of continuous positive airway pressure (CPAP) to the collapsed lung potentially reduces pulmonary damage, hypoxia, and consequent inflammation. This randomized controlled trial studied the influence of CPAP applied to the collapsed right lung during thoracoscopic oesophagectomy on local and systemic inflammatory response. ⋯ A significantly lower local immune response was observed during one-lung ventilation when CPAP was applied to the collapsed lung. The findings suggest a beneficial effect of CPAP on the collapsed lung during oesophagectomy with one-lung ventilation.
