Open Access Abstract Introduction Postoperative care after oesophageal tumour resection holds a high risk of respiratory complications. We therefore aimed to determine the value of systemic inflammatory markers in predicting arterial hypoxaemia as the earliest sign of developing lung injury after oesophageal tumour resection. Methods In a prospective observational study 33 consecutive patients were observed for three days T1-T3 after admission T0 to an intensive care unit following oesophageal tumour resection. The daily highest values of the heart rate axillary temperature leukocyte count and PaCO2 were recorded. Serum C-reactive protein and procalcitonin concentrations and the leukocyte antisedimentation rate LAR were determined at T1 and T2. Respiratory function was monitored 6-hourly measurement of the PaO2 FIO2 ratio and the lowest value was recorded at T3. Patients were categorised as normoxaemic or hypoxaemic using the cutoff value of 300 mmHg for PaO2 FIO2. Results Seventeen out of 33 patients were classified as .
