Fontan completion in reverse order out of necessity: secondary Glenn after primary extracardiac inferior cavopulmonary artery connection.

The primary extracardiac inferior cavopulmonary connection is an unusual novel palliation for single-ventricle physiology, which we first performed in the setting of unfavourable upper-body systemic venous anatomy for a standard bi-directional Glenn, and in lieu of leaving our patient with shunt-dependent physiology. After an initial 16-month satisfactory follow-up, increasing cyanosis led to the discovery of a veno-venous collateral that was coiled, but, more importantly, to impressive growth of a previously diminutive superior caval vein, which allowed us to perform completion Fontan with a good outcome. Performing the single-ventricle staging in a reverse manner, first from below with a primary inferior cavopulmonary connection, followed by Fontan completion from above with a standard superior caval vein bi-directional Glenn, is also possible when deemed necessary.

Antegrade cerebral perfusion at 25 °C for arch reconstruction in newborns and children preserves perioperative cerebral oxygenation and serum creatinine.

Background: Antegrade cerebral perfusion (ACP) typically is used with deep hypothermia for cerebral protection during aortic arch reconstructions. The impact of ACP on cerebral oxygenation and serum creatinine at a more tepid 25 °C was studied in newborns and children.

Methods: Between 2010 and 2014, 61 newborns and children (<5 years old) underwent aortic arch reconstruction using moderate hypothermia (25.

Percutaneous Closure of Perimembranous Ventricular Septal Defects Using the Second-Generation Amplatzer Vascular Occluders.

Earlier attempts at percutaneous closure of perimembranous ventricular septal defects (Pm VSDs) were abandoned because of incidence of heart block likely as a result of device rigidity and/or oversizing. This is retrospective review and data reporting of patients who underwent percutaneous closure using the softer second-generation Amplatzer vascular occluders; namely the Amplatzer vascular plug, second generation, (AVP II) and the Amplatzer duct occluder, second generation (ADO II) in our institution. A total of 20 patients were identified; AVP II was used in 9 patients and ADO II in 11 patients.

When the bi-directional Glenn is an unfavourable option: primary extracardiac inferior cavopulmonary connection as an alternative palliation.

The superior cavopulmonary anastomosis - bi-directional Glenn - is the standard palliation for single ventricle physiology. When upper body systemic venous anatomic concerns such as superior caval vein stenosis, hypoplasia, or inadequate collateral tributaries are present, a Glenn may be precluded or have a high risk of poor outcome. A primary inferior cavopulmonary connection with an extracardiac conduit is an alternative palliation that provides a generous pathway for pulmonary blood flow, with the additional benefit of including hepatic venous return.

Presurgical fentanyl vs caudal block and the incidence of adverse respiratory events in children after orchidopexy.

Background: 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.

Caffeine in children with obstructive sleep apnea.

Background: Children with obstructive sleep apnea (OSA) have a higher rate of adverse post-extubation respiratory events, such as laryngospasm, upper airway obstruction, apnea, desaturation and/or need for re-intubation. They are overly sensitive to sedatives and narcotics. Although the etiology of OSA is primarily obstruction (mechanical or neuromuscular), a central element may contribute to OSA.

Caudal regional anesthesia, ropivacaine concentration, postoperative analgesia, and infants.

In this randomized, double-blind trial we evaluated the quality and duration of analgesia and motor effects after caudal block using 1 mL/kg of ropivacaine 0.1% (Group 1), 0.15% (Group 2), 0.
