Oxygen desaturation during maximal stair-climbing test and postoperative complications after major lung resections.
Non-univocal conclusions have been published regarding the definition of oxygen desaturation in relation to postoperative outcome. We aimed to verify whether oxygen desaturation during a maximal stair-climbing test was associated with postoperative cardiopulmonary complications and to assess which definition of oxygen desaturation (oxygen saturation <90% or desaturation >4% with respect to rest level) discriminated better between complicated and uncomplicated patients. ⋯ A stair-climbing test is an intense constant workload exercise, challenging a large amount of muscle mass, and appears particularly appropriate to elicit oxygen desaturation, which in turn may be a reliable marker of deficits in the oxygen transport system. A desaturation >4% appears a better cut-off definition than a saturation level <90% in predicting the occurrence of complications. The risk of complications was approximately two-fold higher in patients with oxygen desaturation >4% at peak exercise.

Esmolol before 80 min of cardiac arrest with oxygenated cold blood cardioplegia alleviates systolic dysfunction. An experimental study in pigs.
Myocardial dysfunction after reperfusion can be a clinical problem in the early postoperative phase after on-pump cardiac surgery. The aim was, in an experimental setting, to investigate if administration of the beta-adrenergic receptor blocker esmolol prior to cross-clamping for 80 min with cold oxygenated blood cardioplegia would improve myocardial protection and early postoperative function. ⋯ Esmolol administered prior to cold oxygenated cardioplegic arrest alleviates left ventricular dysfunction in the early hours after cardiopulmonary bypass.

Randomized Controlled TrialPreoperative pulmonary rehabilitation in patients undergoing lung resection for non-small cell lung cancer.
The impact of short-term preoperative pulmonary rehabilitation on exercise capacity of patients with chronic obstructive pulmonary disease undergoing lobectomy for non-small cell lung cancer is evaluated. ⋯ Short-term preoperative pulmonary rehabilitation could improve the exercise capacity of patients with chronic obstructive pulmonary disease who are candidates for lung resection for non-small cell lung cancer.

Biventricular repair in children with complete atrioventricular septal defect and a small left ventricle.
Biventricular repair of complete atrioventricular septal defect (CAVSD) with small left ventricle aims to restore the normal loading conditions of the left ventricle. This report retrospectively evaluates the outcome of biventricular repair in 19 children with CAVSD and a small left ventricle. ⋯ Biventricular repair of CAVSD with small left ventricle in infants and children whose LAR is >0.65, although not without risks, improve patients' functional and clinical status even in long-term follow-up. Particular caution should be taken in patients with LAR of <0.65, since these are patients who may not be amenable to biventricular repair, but for whom univentricular palliation may be more suitable.

Case ReportsPlacental transmogrification of the lung presenting as giant bullae with soft-fatty components.
A 44-year-old man presented with progressive dyspnea and a previous pneumothorax. Chest CT scan showed a mediastinal shift due to giant bullae containing soft tissue and fatty components in the left lower lung lobe, and a right upper lung lobe partially collapsed. The pulmonary function tests revealed forced vital capacity (FVC) 53% (of the predicted) and forced vital capacity in 1s (FEV1) 52%. ⋯ The pathological examination showed a placental transmogrification of the lung (PTL). One month after the surgery, the patient was asymptomatic, the pulmonary function tests normalized and the upper lobe was well expanded. In conclusion, we described the first CT finding of soft tissue and fatty components within the PTL-related bullae, and the PTL should be considered in the differential diagnosis of pulmonary lesions with soft-fatty and air components.
