ReviewBenefits and risks of red blood cell transfusion in pediatric patients undergoing cardiac surgery.
As the number of neonates and young infants undergoing cardiac surgery requiring cardiopulmonary bypass (CPB) increases, red blood cell (RBC) transfusion will continue to be an integral part of the practice of pediatric cardiac anesthesiology. The decision of when to transfuse RBCs to these patients is complex and influenced by multiple factors such as size, presence of cyanotic heart disease, complexity of the surgical procedure, and the hemostatic alterations induced by CPB. The known benefits of RBC transfusion include an increase in the oxygen-carrying capacity of blood, improved tissue oxygenation, and improved hemostasis. ⋯ However, a growing number of prospective randomized clinical trials are finding an association between RBC transfusion and an increased risk of morbidity and mortality even with the use of leuko-reduced blood. Thus, it is becoming increasingly important that the decision to transfuse RBCs be made with a thorough understanding of the benefit-to-risk ratio. This review addresses the benefits and risks of RBC transfusion, pertinent data acquired in the setting of congenital cardiac surgery and techniques designed to minimize the need for RBC transfusion.

ReviewPediatric pacemakers and ICDs: how to optimize perioperative care.
An increasing number of pediatric patients with permanent pacemakers and implantable cardioverter defibrillators (ICDs) require cardiac and noncardiac surgery. It is critical that the anesthesiologist caring for these patients understands the management of the device and the underlying heart disease. Children with these devices are more vulnerable to lead failure and inappropriate shocks compared with the adult population. ⋯ Prior consultation with qualified programmers is recommended to enable timely optimization of the device. Magnets may be used in emergency situations but it is important to appreciate the limitations of magnet use on different models of pacemakers and ICDs. Safe and successful perioperative care is dependent upon a well-organized and coordinated multidisciplinary team approach.

ReviewCerebral oximetry for pediatric anesthesia: why do intelligent clinicians disagree?
Reflectance near-infrared spectroscopy has been used to measure cortical tissue oximetry for more than 30 years. In that time, many centers have adopted the routine use of the cerebral oximeter for children having repair of congenital heart lesions, while some prominent academic centers have resisted routine use of these monitors citing lack of definitive evidence for outcome benefit. ⋯ We discuss the peculiarities of evidentiary review for monitoring devices, and the confounding errors that occur when a monitor is evaluated as a therapeutic intervention. We outline the physiologic basis of cerebral desaturation and the shifts in practice that have occurred with implementation of NIRS monitoring.

ReviewRole of transesophageal echocardiography in the management of pediatric patients with congenital heart disease.
Transesophageal echocardiography (TEE) has become a critical diagnostic and perioperative management tool for patients with congenital heart disease (CHD) undergoing cardiac and noncardiac surgical procedures. This review highlights the role of TEE in routine management of pediatric cardiac patient population with focus on indications, views, applications and technological advances.

In recent years, the importance of appropriate intra-operative anesthesia and analgesia during cardiac surgery has become recognized as a factor in postoperative recovery. This includes the early perioperative management of the neonate undergoing radical surgery and more recently the care surrounding fast-track and ultra fast-track surgery. ⋯ Management of the marginal patient requires optimisation of not only cardiac and other attendant pathophysiology, but also every aspect of supportive care. Individualized sedation and analgesia strategies, starting in the operating theater and continuing through to hospital discharge, need to be regarded as an important aspect of perioperative care, to speed the process of recovery.
