Alveolar recruitment strategy and PEEP improve oxygenation, dynamic compliance of respiratory system and end-expiratory lung volume in pediatric patients undergoing cardiac surgery for congenital heart disease.
Optimizing alveolar recruitment by alveolar recruitment strategy (ARS) and maintaining lung volume with adequate positive end-expiratory pressure (PEEP) allow preventing ventilator-induced lung injury (VILI). Knowing that PEEP has its most beneficial effects when dynamic compliance of respiratory system (Crs) is maximized, we hypothesize that the use of 8 cm H(2)O PEEP with ARS results in an increase in Crs and end-expiratory lung volume (EELV) compared to 8 cm H(2)O PEEP without ARS and to zero PEEP in pediatric patients undergoing cardiac surgery for congenital heart disease. ⋯ An alveolar recruitment strategy with relative high PEEP significantly improves Crs, oxygenation, P(a)CO(2)- PETCO(2) difference, and EELV in pediatric patients undergoing cardiac surgery for congenital heart disease.

Review Meta AnalysisUltrasound guided internal jugular vein access in children and infant: a meta-analysis of published studies.
Central venous catheter placement is technically difficult in pediatric population especially in the younger patients. Ultrasound prelocation and/or guidance (UPG) of internal jugular vein (IJV) access has been shown to decrease failure rate and complications related to this invasive procedure. The goal of the present study was to perform a systematic review of the advantages of UPG over anatomical landmarks (AL) during IJV access in children and infants. ⋯ This current meta-analysis does not found the utility of ultrasound during IJV access in children and infants in increasing the success rate and in decreasing complications.

Randomized Controlled Trial Comparative StudyPresurgical fentanyl vs caudal block and the incidence of adverse respiratory events in children after orchidopexy.
There is controversy about the etiology of early postoperative hypoxemia. Age, weight, intubation, surgical procedure, use of muscle relaxants, and/or administration of opioids may affect the incidence of early postoperative hypoxemia. In this prospective, randomized, and single-blinded study, we evaluated whether the administration of caudal analgesia vs i.v. fentanyl affected the number of children who develop postextubation adverse upper airway respiratory events, (upper airway obstruction, laryngospasm) and/or early postoperative hypoxemia. ⋯ Compared to fentanyl, placement of a presurgical caudal block in boys scheduled for orchidopexy was associated with a lower incidence of postextubation adverse upper airway respiratory events and/or early postoperative hypoxemia.
