In those aged recovery operation was prolonged because their diaphragmatic palsy made it difficult to wean them from ventilator. Older symptoms but rate did not seem be affected by Phrenic damage no more frequent a lateral thoracotomy median sternotomy. There significant association with type performed, experience surgeon, use bypass topical ice, duration bypass, circulatory arrest aortic cross clamping, patient at time patients who cardiopulmonary risk injury significantly higher undergone previous The 10% frequency determined this prospective study that seen earlier retrospective reports. Direct can used bedside facilitate early accurate diagnosis palsy, results may influence management.
