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 2: Anesthesia-related risk and treatment options.
Perioperative respiratory adverse events are the most common cause of critical events in children undergoing anesthesia and surgery. While many risk factors remain unmodifiable, there are numerous anesthetic management decisions which can impact the incidence and impact of these events, especially in at-risk children. Ongoing research continues to improve our understanding of both the influence of risk factors and the effect of specific interventions. This review discusses anesthesia risk factors and outlines strategies to reduce the rate and impact of perioperative respiratory adverse events with a chronologic based inquiry into anesthetic management decisions through the perioperative period from premedication to postoperative disposition.

ReviewUnderstanding pediatric ventilation in the operative setting. Part II: Setting perioperative ventilation.
Approaches toward lung-protective ventilation have increasingly been investigated in recent years. Despite evidence being found in adults undergoing surgery, data in younger children are still scarce and controversial. ⋯ The modern anesthesia workstation provides such information, with the technical strengths and weaknesses being discussed in a review preceding the present work (see Part I). The present summary aims to provide ideas on how to translate the information displayed on the anesthesia workstation to patient-oriented clinical ventilation settings.

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.
