Pericardiocentesis, thoracentesis, and paracentesis
Objectives/indications The presence of a pericardial effusion, pleural effusion, or ascites may warrant emergent drainage via pericardiocentesis, thoracentesis, or paracentesis, respectively. Though these are rare conditions in children, point-of-care ultrasound…
Pulmonary ultrasound
