Randomized Controlled Trial Clinical TrialTechnique to reduce air leaks after pulmonary lobectomy.
Patients undergoing pulmonary resections often present postoperative air leaks of varying magnitude and duration; this complication is more frequent with incomplete or absent interlobar fissures. Small leaks close spontaneously within 5-7 days; larger leaks may persist longer and could be associated with increased morbidity and prolonged hospitalization. We evaluated the role of different techniques to complete interlobar fissures before pulmonary lobectomy to prevent postoperative air leaks and reduce hospital stay and costs. ⋯ The use of GIA staplers and pericardial sleeves to complete interlobar fissures for pulmonary lobectomy significantly reduces the duration of postoperative air leaks and hospital stay; no complications were associated with this technique.

Cerebral oxygenation during paediatric cardiac surgery: identification of vulnerable periods using near infrared spectroscopy.
Neurologic sequelae remain a well recognised complication of paediatric cardiac surgery. Monitoring of cerebral oxygenation may be a useful technique for identifying vulnerable periods for the development of neurologic injury. We sought to measure regional cerebral oxygenation in children undergoing cardiac surgery using near infrared spectroscopy to ascertain such vulnerable periods. ⋯ These observations suggest that the pre- and early post-bypass periods are vulnerable times for provision of adequate cerebral oxygenation. Near infrared spectroscopy is a promising tool for monitoring O2 supply/demand relationships especially during circulatory arrest.

Long-term prognosis of surgically-treated aortic aneurysms and dissections in patients with and without Marfan syndrome.
Aortic aneurysms and dissections are the leading causes of premature death in Marfan syndrome (MfS). This study aims to compare long-term results of surgically treated aortic aneurysms and dissections in patients with and without MfS in respect to early and late prognosis. ⋯ Surgical treatment of aortic disease in MfS patients is associated with a high risk of redissection and recurrent aneurysm. If the ascending aorta needs to be replaced, we recommend the composite graft technique and a more aggressive approach to reduce the frequency of distal reoperations. In order to reduce the high reoperation rate in MfS patients, frequent clinical follow-up may contribute to improve life expectancy in MfS patients.

von Willebrand factor and urinary albumin excretion are possible indicators of endothelial dysfunction in cardiopulmonary bypass.
Experimental evidence suggests that cardiopulmonary bypass (CPB) associated inflammatory response leads to endothelial injury and increased permeability, but this has been difficult to show clinically. We have investigated the use of von Willebrand factor (vWF), and urinary albumin excretion, as measured by the urinary albumin creatinine ratio (ACR), to demonstrate this. ⋯ These results demonstrate that endothelial permeability and injury, as measured by urinary albumin excretion and vWF, respectively, are related and the use of these easily detectable and sensitive biochemical markers warrants further investigation.

Cardiac troponin I as an early marker of myocardial damage after coronary bypass surgery.
To evaluate the performance of cardiac specific markers, cardiac troponin I (cTnI) and CK-MB by mass assay (CK-MB mass), for the early diagnosis of myocardial ischemia and/or infarction after coronary bypass surgery. ⋯ As soon as 6 h postoperatively, cTnI and CK-MB by mass assay were able to separate those patients with an uneventful recovery from those with significant ischemia. This is particularly useful in frequent cases when the ECG is difficult to interpret.
