ObjectivesThis study evaluated the role of ultrasound in postoperative care after major lung resection.BackgroundHigh accuracy of lung ultrasound imaging was proved in various medical fields. The experience with ultrasound after thoracic surgery is limited.MethodsPatients scheduled for major lung resection were consecutively included in a prospective study comparing two modalities of imaging examinations, namely those employing ultrasound and X-ray in the diagnoses of pneumothorax and pleural effusion. Two examinations were performed. One after recovery from anaesthesia, the second before chest tube removal.ResultsForty-eight patients underwent 87 examinations. X-ray and ultrasound examinations showed substantial and fair agreements for pneumothorax (Cohen's kappa coefficients 0.775 and 0.397) and slight and substantial agreements for pleural effusion (Cohen's kappa coefficients 0.036 and 0.611). The sensitivity bounds for pneumothorax were 45.5-58.5 % at the first and 29.7-59.4 % at the second examination. Sensitivity bounds for pleural effusion were 0-86.2 % at the first and 32.6-36.9 % at the second examination. Except for two cases of pneumothorax being missed by X-ray imaging, the rest of mismatches were clinically irrelevant conditions with no impact on clinical decision and patient's outcome.ConclusionThe use of ultrasound can reduce the number of X-ray examinations and thus lower the radiation exposure after major lung resections (Tab. 4, Ref. 30).
