Descending aortic and innominate artery cannulation for aortic arch repair with mildly hypothermic continuous cardiopulmonary bypass in infants and children.

A technique is described for exposure of the descending aorta, allowing separate arterial cannulation for perfusion of the upper and lower body during reconstruction of the aortic arch, maintaining continuous full-flow cardiopulmonary bypass to the entire body. This single technique is applicable to all aortic arch pathologies and allows an unhurried aortic reconstruction in an unobstructed field.

Newborn aortic arch reconstruction with descending aortic cannulation improves postoperative renal function.

Background: A clinically driven transition in perfusion technique occurred at Children's Hospital and Medical Center, Omaha, Nebraska, from primarily selective cerebral perfusion bracketed by brief periods of deep hypothermic circulatory arrest to a technique of dual arterial perfusion including innominate artery and descending aortic cannulation (DAC), with continuous mildly hypothermic (>30 °C) full-flow cardiopulmonary bypass to the entire body. This study retrospectively compared outcomes in a recent cohort of neonates undergoing aortic arch reconstruction with the two techniques.

Methods: The clinical records of 142 consecutive neonates undergoing operations involving aortic arch reconstruction at a single institution between April 2004 and September 2012 were reviewed.

Successful use of venovenous extracorporeal membrane oxygenation for complicated H1N1 pneumonia refractory to mechanical ventilation.

In April 2009, novel H1N1 influenza A pneumonia was initially identified in young adults by the Mexican Health Ministry. Previously healthy patients progressing to multisystem organ failure were common. Worldwide, hospitals reported surges in intensive care admissions during the initial phase of the pandemic.

Extended support with the Terumo Baby-RX oxygenator.

The Terumo Baby-RX, a new-generation low prime oxygenator, recently has entered the perfusion market in North America. This oxygenator is designed exclusively for neonates and infants and has the smallest priming volume of any clinically available oxygenator. The BABY-RX also is treated with X Coating, Terumo's biocompatible, hydrophilic polymer surface coating that reduces platelet adhesion and protein denaturation.

A technique for performing antegrade selective cerebral perfusion without interruption of forward flow or cannula relocation for pediatric aortic arch reconstruction.

New technology and advances in extracorporeal bypass circuitry and surgical techniques have drastically improved outcomes in infants with congenital heart defects. Hypothermia with circulatory arrest has fallen out of favor in many institutions over the last decade in part from data implicating even short circulatory arrest times to long-term neurologic sequelae. Implementing continuous cerebral perfusion techniques for aortic arch reconstruction is desirable in ameliorating neurologic complications because long-term survival of complex defects can be more routinely achieved.
