Identifying complications early and ‘at risk' patients may allow us to target more effective therapy. Thus we evaluated the viability of a novel portable device to measure dynamic thoraco-abdominal/lung function immediately after lung resection.METHODS: Structured Light Plethysmography (SLP) measures both rib cage and abdominal motion using a light grid which is simultaneously ‘seen' by a digital vision system. Grid movement during breathing is analysed and displayed in terms of regional thoraco-abdominal movement parameters as well as a 3D reconstruction. Measurements were made during quiet breathing, before and up to 4 days post operatively.RESULTS: 9 male patients with a mean age of 72 (range from 63 to 82) years, who underwent lung resection either via VATS (n:4) or Thoracotomy (n:5) were recruited. 96 % of all planned measurements could be performed, all without complications or discomfort to patients. SLP detected a significant reduction in the rib cage contribution to overall ventilation on the operated side in all patients one day after surgery compared to pre-operative measures (7% +/- 5.4 % p<0.001). This impairment was more marked following Thoracotomy (9% +/- 5% p<0.001) than VATS (4.5% +/- 4.6% p<0.001) and did not significantly improve prior to hospital discharge.CONCLUSION: SLP is a feasible, acceptable safe technique that can detect immediate regional changes in ventilation following lung resection and differentiate types of surgery. Further studies are required to determine usefulness of measures. ER -
