Abstract:
Morgagni hernia in adults is a rare condition and is associated with complications such as recurrent chest infections, respiratory failure and cardiac tamponade. Its correction represents an anesthetic challenge. Intraoperative esophageal Doppler provides important information in real time about the patient's cardiac function and vascular filling, aiding in decision making by the anesthesiologist. We report a case of a 70-year-old woman, ASA Physical Status-III, and presented with chest pain, dyspnea and hypoxemia. Her chest x-ray revealed opacification of 2/3 of the left hemithorax and 1/2 of the right. Computed tomography confirmed a bilateral Morgagni hernia. The patient underwent immediate corrective surgery. Intraoperative cardiovascular function was monitored with esophageal Doppler. Compression and decompression of thoracic structures produces enormous hemodynamic and respiratory impact. After herniated contents removal it showed an increase in systolic volume and cardiac index and a correction of flow time. Transient arterial hypotension was verified, requiring fluid therapy and vasopressor support. Diaphragmatic defect was corrected and general hemodynamic stabilization was achieved. Patient was discharged asymptomatic. The esophageal Doppler was important in this case because it allowed us to measure fundamental hemodynamic variables in real time, such as cardiac index or systolic volume, and to subsequently act accordingly.
