Perioperative lung ultrasound is a continuously evolving modality with numerous applications for the pediatric anesthesiologist. Lung ultrasound can be used at the bedside, including intraoperatively, to augment traditional physical examination methods of assessing cardiopulmonary structures and identifying the presence of specific and clinically significant pathology. ⋯ With its relative ease of performance, lung ultrasound should be considered in the initial evaluation of intraoperative hypoxemia particularly when traditional modes of evaluation are nonexplanatory. This educational review introduces the basic concepts of lung ultrasound as they relate to pediatric anesthesia patients.

ReviewRisk assessment and optimization strategies to reduce perioperative respiratory adverse events in pediatric anesthesia-Part 1 patient and surgical factors.
Pediatric surgery cases are increasing worldwide. Within pediatric anesthesia, perioperative respiratory adverse events are the most common precipitant leading to serious complications. They can have intraoperative impact on the surgical procedure itself, lead to premature case termination and in addition may have postoperative impact resulting in longer hospitalization stays and costs. ⋯ The incidence of respiratory adverse events increases in children with comorbid respiratory and/or nonrespiratory illnesses. Optimized perioperative patient care, risk-stratified care level choice, and practitioners with appropriate training allow for risk mitigation. This review will discuss patient and surgical risk factors with a focus on common patient comorbid illnesses and review scoring systems to quantify risk.

Bronchopulmonary dysplasia is the most frequent adverse outcome of prematurity. Before implementation of antenatal steroids and surfactant therapy, bronchopulmonary dysplasia was mostly characterized by fibrotic, scarred, and hyper-inflated lungs due to pulmonary injury following mechanical ventilation and oxygen toxicity. With advances in neonatal medicine, this "old" bronchopulmonary dysplasia has changed to a "new" bronchopulmonary dysplasia characterized by an arrest in lung growth, leading to alveolar simplification and pulmonary vascular dysangiogenesis. ⋯ Medical treatment often includes diuretics, steroids, bronchodilators, or oxygen supplementation and in the presence of pulmonary hypertension medication to decrease the pulmonary vascular resistance. Perioperative anesthetic risk is increased in children with pulmonary hypertension. These patients might require additional diagnostic imaging and plans for increased resource allocation such as postoperative intensive care admission.

ReviewModes of ventilation for pediatric patients under anesthesia: A Pro/Con conversation.
The development of sophisticated modes of ventilation for pediatric patients undergoing anesthesia is ongoing; what remains a challenge for the pediatric anesthesiologist is thoughtful selection of the mode(s) of ventilation for a particular patient in the context of the surgical procedure and the goals of the anesthetic. This article provides some historical accounting of a variety of modes of ventilation, defines the terminology of modern ventilatory modes, and reviews in detail the benefits and pitfalls of the specific modes of ventilation and their applicability to the practice of pediatric anesthesiology. In an attempt to debate the Pros and Cons of different modes of ventilation, and to finally resolve the debate "spontaneous vs. controlled ventilation," we share with you a thoughtful conversation of the continuum of modes of ventilation and their applicability to our pediatric anesthesia population.

ReviewNoninvasive ventilation in children: A review for the pediatric anesthesiologist.
Preserving adequate respiratory function is essential in the perioperative period. Mechanical ventilation with endotracheal intubation is widely used for this purpose. In select patients, noninvasive ventilation (NIV) may be an alternative to invasive ventilation or may complement respiratory management. ⋯ HFNO delivers humidified and heated oxygen at rates between 2 and 70 L/min using specific nasal cannulas, and flows are determined by the patient's weight and clinical needs. HFNO can be useful as a method for preoxygenation in infants and children by prolonging apnea time before desaturation, yet in children with decreased minute ventilation or apnea HFNO does not improve alveolar gas exchange. Clinicians experienced with these devices, such as pediatric intensivists and pulmonary medicine specialists, can be useful resources for the pediatric anesthesiologist caring for complex patients on NIV.
