Comparative Study
A single-center experience of extubation failure in infants undergoing the Norwood operation.
Identify incidence, etiology, and predictors of extubation failure in neonates and infants who underwent Norwood operation with either a modified Blalock-Taussig shunt (mBTS) or a Sano shunt at a single tertiary care, academic children's hospital. ⋯ Extubation failure in children after the Norwood operation is a slow and evolving process occurring as late as 96 hours after extubation and is not associated with an increase in in-hospital mortality. Causes of failed extubation are diverse. Successful weaning from positive pressure ventilation depends on adequate cardiovascular function, the presence of satisfactory ventilatory reserves, and favorable pulmonary mechanics.

Comparative Study
Thoracoscopic talc versus tunneled pleural catheters for palliation of malignant pleural effusions.
A malignant pleural effusion (MPE) is a late complication of malignancy that affects respiratory function and quality of life. A strategy for palliation of the symptoms caused by MPE should permanently control fluid accumulation, preclude any need for reintervention, and limit hospital length of stay (LOS). We compared video-assisted thorascopic (VATS) talc insufflation with placement of a tunneled pleural catheter (TPC) to assess which intervention better met these palliative goals. ⋯ TPC placement was associated with a significantly reduced postprocedure and overall LOS compared with VATS talc. Also, TPC placement was associated with significantly fewer ipsilateral reinterventions. Placement of TPC should be considered for palliation of MPE-associated symptoms.

Comparative Study
Postoperative assessment of laryngopharyngeal dysfunction in neonates after Norwood operation.
The purpose of this study was to evaluate the incidence of vocal cord (VC) and swallowing dysfunction in infants after the Norwood operation and to examine the relationship between laryngopharyngeal dysfunction and postoperative outcomes. ⋯ Vocal cord and swallowing dysfunction are common in infants after the Norwood operation and may increase the need for tube feeding regimens. Modification of surgical techniques for dissection and mobilization of the aorta can significantly reduce the incidence of these adverse outcomes.

Impact of preoperative anemia on outcome in adult cardiac surgery: a propensity-matched analysis.
Preoperative anemia is not considered an operative mortality risk factor by the majority of the risk stratification tools used in cardiac surgery. However, retrospective studies have found associations between preoperative anemia and morbidity and mortality in cardiac operations. The present study compares the postoperative outcome of a group of moderate-to-severe anemic patients with a propensity-matched group of nonanemic patients undergoing cardiac operations. ⋯ Moderate-to-severe preoperative anemia is a risk factor for major morbidity and operative mortality in adult cardiac operations. This finding is confirmative of the role of preoperative anemia in determining adverse events in major noncardiac operations. The exclusion of preoperative anemia from the existing risk scores is probably a statistical consequence of the associated comorbid conditions that confound the specific role of anemia as a risk factor.

An interventional lung assist membrane ventilator (iLA) for arteriovenous extracorporeal CO2 removal was connected to a small-diameter femoral artery by use of a chimney graft in an underweight patient with acute respiratory failure and a previous history of heart-lung transplantation. This concept offers additional therapeutic options in underweight patients requiring extracorporeal CO2 removal with arterial vessels that are too small for percutaneous arterial cannulation with standard-sized percutaneous insertable iLA cannulae.
