Ventilator-associated pneumonia (VAP) is a nosocomially acquired infection that has a significant burden on intensive care units (ICUs). We investigated the incidence of VAP in children after cardiac surgery and its impact on morbidity and mortality. A prospective cross-sectional review was performed in the postoperative cardiac patients in pediatric cardiac intensive care unit (PCICU) patients from March 2010 until the end of September 2010. ⋯ VAP incidence is high in children after cardiac surgery mainly by GNB. VAP increases with longer CPB time, administration of TPN, and longer PCICU stay. VAP increases morbidity in postoperative cardiac patients.

Splanchnic oxygen saturation immediately after weaning from cardiopulmonary bypass can predict early postoperative outcomes in children undergoing congenital heart surgery.
This study compared the abilities of cerebral, renal, and splanchnic regional oxygen saturation (rSO2) immediately after weaning from cardiopulmonary bypass (CPB) to predict early postoperative outcomes for children undergoing congenital heart surgery. The study enrolled 73 children (ages 0.1-72 months) undergoing corrective or palliative cardiac surgery requiring CPB. Laboratory and hemodynamic variables were analyzed at the time of successful weaning from CPB. ⋯ However, splanchnic rSO2 was the only independent factor predicting VIS(max) (β = -0.302, P = 0.021), duration of mechanical ventilation (β = -0.390, P = 0.002), and postoperative hospital length of stay (β = -0.340, P = 0.001) by multivariate analyses. Splanchnic rSO2 had a larger receiver operating characteristic area under the curve (AUC) for determining high VIS(max), prolonged mechanical ventilation, and longer postoperative hospital stay (AUC 0.775, 0.792, and 0.776, respectively) than cerebral (AUC 0.630, 0.638, and 0.632, respectively) and renal (AUC 0.703, 0.716, and 0.715, respectively) rSO2. After weaning from CPB, splanchnic rSO2 may be superior to rSO2 measured from brain and kidney in predicting an increased requirement for vasoactive inotropic support, a prolonged mechanical ventilation, and a longer postoperative hospital stay for children.

Tachyarrhythmias after the Norwood procedure: relationship and effect of vasoactive agents.
Tachyarrhythmias are common after the Norwood stage I palliation. The effects of vasoactive medications on the development of post-operative tachyarrhythmias have not been studied. The primary objective was to identify associations between postoperative tachyarrhythmias and vasoactive medication usage after Norwood stage 1 palliation. ⋯ Postoperative tachyarrhythmias are common after the Norwood procedure and are associated with longer ICU and hospital stays. High doses of milrinone, longer duration of epinephrine treatment, and the right ventricle to pulmonary artery shunt were associated with for the development of tachyarrhythmias. Further studies are required to determine the effects of anatomy on post-operative tachyarrhythmias.

Multicenter StudyHealth-related quality of life experienced by children with chromosomal abnormalities and congenital heart defects.
Long-term outcomes are fundamental in advising parents about the potential future of their children with congenital heart disease (CHD). No published reports have described the health-related quality of life (HRQL) experienced by children with chromosomal abnormalities who had surgery in early infancy for CHD. A study was undertaken to assess HRQL among children with chromosomal abnormalities and CHD. ⋯ The children with chromosomal abnormalities and CHD had significantly lower mean total PedsQL (71.3 vs. 87.3; p < 0.0001), Psychosocial Summary (70.3 vs. 86.1; p < 0.0001), and Physical Summary (74.3 vs. 89.2; p = 0.0006) scores. Compared with the matched children, those with chromosomal abnormalities had a significantly lower median total PedsQL (75.0 vs. 84.6; p = 0.03), Physical Summary (79.5 vs. 96.9; p = 0.007), and School Functioning (68.5 vs. 83.0; p = 0.03) scores. A better understanding of the mechanisms and determinants of HRQL in these children has the potential to yield important implications for clinical practice including clarity for treatment decision making as well as determination of targeted supports and services to meet the needs of these children and their families differentially.

Predictors of prolonged length of intensive care unit stay after stage I palliation: a report from the National Pediatric Cardiology Quality Improvement Collaborative.
The objective of this study is to identify predictors of prolonged intensive care unit (ICU) length of stay (LOS) for single ventricle patients following Stage I palliation. We hypothesize that peri-operative factors contribute to prolonged ICU stay among children with hypoplastic left heart syndrome (HLHS) and its variants. In 2008, as a part of the Joint Council on Congenital Heart Disease initiative, the National Pediatric Cardiology-Quality Improvement Collaborative established a data registry for patients with HLHS and its variants undergoing staged palliation. ⋯ Multivariate analysis revealed that lower number of enrolled participants (e.g., 1-10) per site, the presence of pre-operative acidosis, increased circulatory arrest time, the occurrence of a central line infection, and the development of respiratory insufficiency requiring re-intubation were associated with prolonged LOS in the ICU. Prolonged LOS in the ICU following Stage I palliation in patients with HLHS and HLHS variant anatomy is associated with site enrollment, circulatory arrest time, pre-operative acidosis, and some post-operative complications, including central line infection and re-intubation. Further study of these associations may reveal strategies for reducing LOS in the ICU following the Norwood and Norwood-variant surgeries.
