Measurement of Diaphragmatic Dysfunction After Thoracic Surgery

Measurement of Diaphragmatic Dysfunction in Patients Undergoing Thoracic Resection Surgery for Lung- or Esophageal Cancer

This study aims to measure diaphragmatic dysfunction with ultrasonography and nerve stimulation of the phrenicus nerve, in patients undergoing thoracic surgery for lung and esophageal cancer, and correlate measures of diaphramatic function to clinical postoperative endpoints.

Inclusion Criteria:

• Scheduled thoracic resection Surgery for lung- or esophagus cancer. For lung cancer patients, at least one lung lobe has to scheduled for resection

Exclusion Criteria:

• Known Diaphragmatic Dysfunction
• Neuromuscular Disease
• Pleural Effusion > 1cm
• Pneumothorax
• Known Phrenic Nerve Palsy
