1. Glycemic Control, Cardiac Surgery, and Infection Glycemic control after cardiac surgery has been somewhat controversial. Congenital heart defects are the most common birth defects in children with relatively higher postoperative morbidity and mortality are relatively high. Tight glucose control has been hypothesized as a potential mode for preventing or reducing morbidity and mortality. The incidence of hyperglycemia (≥ 126 mg/dL) has been reported to be as high as 90% in some studies. In a study performed in post-cardiac surgery pediatric intensive care unit by Vlasselaers et. al. (Intensive insulin therapy for patients in paediatric intensive care: a prospective, randomised controlled study. Lancet. 2009;373:547-556.) showed that normalizing glucose postoperatively can reduce mortality from 6% to 3%, shorten length of stay, and reduce overall morbidity. A contrasting study published by Agus et. al. (Tight glycemic control versus standard of care after pediatric surgery. N Engl J Med. 2012;367:1208-1219) cardiac surgery patients in two different US centers undergoing cardiopulmonary bypass suggets a different view point. In the study, investigators maintained an aim to achieve a blood glucose of 80-110 mg/dL. They used a subcutaneous glucose monitor and an explicit insulin dosing algorithm. They enrolled 989 patients, 9 of whom were excluded, for a total of 980 children up to 3 years of age. A total of 24 healthcare-associated infections occurred in both groups, with no difference between groups (8.6 vs 9.9 infections per 1000 patient days). Although they normalized glucose more rapidly (6 hours vs 16 hours)
postoperatively, and normoglycemia was maintained for a greater proportion of critical illness phase (50% vs 33%), they still were unable to achieve a significant reduction in healthcare-associated infections. This study shows that a normalization of blood glucose postoperatively in pediatric cardiac surgery patients in the intensive care unit has no impact on postoperative morbidity or mortality. Tight glucose control can raise the risk for hypoglycemia (which was actually rare in this study at 3%) and doesn't produce any benefit for these post-cardiac surgery patients.
2.Vitamin D deficiency is associated with poor outcomes anincreased mortality in severely ill patients. Vitamin D plays a seminal role in many homeostatic mechanisms. In this study, assessement of the correlation between circulating vitamin D levels and mortality rates in critically ill patients is made indicating that low vitamin D levels are common among patients admitted to ICU. Study observed longer survival times among vitamin D sufficient patients. Results indicate that vitamin D concentration may be either a biomarker of survival or a co-factor.
3. Carbon dioxide field flooding reduces neurologic impairment after open heart surgery.
Air emboli released from incompletely deaired cardiac chambers may cause neurocognitive decline after open heart surgery. Carbon dioxide (CO2) field flooding is reported to reduce residual intracavital air during cardiac surgery. A protective effect of carbon dioxide insufflation on postoperative brain function remains unproven in clinical trials. Shorter P300 peak latencies after surgery indicate less brain damage in patients who underwent heart valve operations with CO2 flooding of the thoracic cavity. Even if these findings were not supported by clinical results or neurocognitive test batteries in our cohort, carbon dioxide field flooding has proven efficiency and should be advocated for all patients undergoing open heart surgery.
4. October 14, 2014 (Newest) Insertion and Removal of the Intra-Aortic Balloon Pump
Intra-aortic balloon pump (IABP) counterpulsation has emerged as one of the most effective and most frequently employed methods of mechanical circulatory support. Specifically, it relies on the twin concept of diastolic augmentation and afterload reduction to facilitate the functioning of an ischemic and failing myocardium. The concept was originally proposed by Moulopoulos et al in 1962 and documented improvement in hemodynamic parameters in an experimental animal model. The first clinical report of human use by Adrian Kantrowitz appeared 6 years later in 1968. In the last 4 decades, there have several technological evolutions, which every student and cardiac surgeon must be aware.

- Longer-term survival and health outcomes for children living with congenital heart defects. Paediatrics and Child Health by Knowles Rachel L et al. (Journal subscription required for full article) Abstract: Cardiac function as measured objectively poorly predicts children's activity in daily life and some children are actively limited by personal habit or family concern, which is often inappropriate. Enough is now known about the prevalence of problems that survivors of childhood cardiac surgery experience in the education system that support may be justified, even when the original cardiac condition is no longer an ongoing problem. As mortality after major cardiac surgery in early childhood falls, it becomes clearer that there is a high prevalence of ‘non-cardiac’ problems in survivors. Patient support groups for cardiac children have long lobbied for better access to general paediatric expertise and upcoming organizational changes underwrite this.
- Recent update (Review article): Tetralogy of Fallot repair: Optimal z-score use of transannular patch insertion (TAP). Transannular patching is often required to relieve significant pulmonary annular stenosis during TOF repair. Although recent literature has focused on the deleterious effects of pulmonary regurgitation, inadequate relief of stenosis may increase postoperative morbidity and mortality and re-intervention rate. Patching criteria based on standard pulmonary annular z-score are ambiguous because of the use of varied z-score datasets. This study aims to generate data that could be used to optimise z-score use for patch insertion Criteria that recommends a TAP insertion only when the PA diameter z-score is significantly smaller than -1.3 (i.e. z= -3) may result in significant numbers of patients with an acceptable post-repair gradient.
