Point of Care Ultrasound to Evaluate Diaphragmatic Function in Children Undergoing Thoracic Surgery

Overview

In children undergoing pulmonary resection, the diaphragm function is evaluated using ultrasound before and after surgery to evaluate the incidence of diaphragm dysfunction after pulmonary resection. In addition, we examine if there is a relationship between diaphragmatic dysfunction and pulmonary complications, including postoperative lung atelectasis.
