Intraoperative hypoxia secondary to pneumothorax: The role of lung ultrasound

: Intraoperative pneumothorax during general anesthesia is a dangerous event. It is a possible cause of sudden intraoperative hypoxia, which can be critical especially in high-risk patients such as those with end-stage heart failure. Early diagnosis and effective treatment are essential. We describe the case of a pneumothorax during cardiac transplantation, diagnosed by ultrasound and immediately treated. A good skill in lung ultrasound is advantageous in the management of intraoperative hypoxia, particularly for prompt diagnosis of pneumothorax.
