Acute renal failure (ARF) is an unusual and severe complication which may occur in patients following cardiac surgery. The incidence of ARF is from 1% to 15% (according to some authors up to 40%). The ARF, occurring in the postoperative period and requiring dialysis is an important risk factor for early mortality, while the overall mortality due to this complication is as high as 40% (40% to 90%). ⋯ The incidence of ARF in patients undergoing cardiac surgery was low (2.1%). The incidence of severe ARF (which must be treated with dialysis) was 0.3%. We compared the data obtained at our hospital with those obtained 17 years ago and found a reduction in the incidence of severe ARF after cardiac surgery (0.3% vs. 4%).

The diagnosis of acute myocardial infarction (AMI) and unstable angina is based on typical clinical signs, electrocardiogram (ECG) changes, and serial measurements of characteristic serum enzymes, especially troponins. Today, newer biochemical markers are used in assessing these conditions, as well as minor myocardial damage (MMD). ⋯ CK-MBact (92.3%) showed the highest specificity, followed by c-TnI (88.5%) and c-TnT (75.6%). The sensitivity was low for all markers analyzed. Concerning specificity, CK-MBact proved to be the best biologic marker for the assessment of MMD, followed by c-TnI and c-TnT. Correct clinical assessment according to marker accuracy and discrimination can be achieved by use of c-TnI, however, with a moderate degree of accuracy and discrimination for the detection of MMD in critically ill patients admitted to ICU.

To determine whether sequential change in coagulation parameters such as activated partial thromboplastin time (aPTT), prothrombin time (PT), platelets count and fibrinogen level may predict the outcome of patients in sepsis. ⋯ The coagulation parameters PT, aPTT, platelet count and fibrinogen level can not serve as predictors of outcome in patients with sepsis. Further studies including more discerning coagulation parameters: AT III, D-dimer, soluble fibrin monomer, thrombin/antithrombin complex, plasmin/antiplasmin complex, fibrinopeptid A, fibrinopeptid B are necessary to evaluate whether these procoagulant and anticoagulant factors may help in predicting outcome and severity of sepsis.

It is not precisely defined which group of non-cardiac surgery patients should undergo transthoracic echocardiography in preoperative preparation. This study was prospectively performed to find out whether the routine use of echocardiography is justified in patients scheduled for lung resection, and to assess its role in cardiac risk evaluation. ⋯ Transthoracic echocardiography is not justified in the routine preoperative preparation of thoracosurgical patients classified as ASA III with clinically minor and intermediate indexes of increased cardiovascular risk. It should be done in selected patients, primarily those that have history data and clinical picture consistent with major indices of an increased cardiovascular risk.

The incidence of congenital diaphragmatic hernia (CDH) is about 4.8/10,000 live births. Its typical clinical presentation is respiratory distress occurring immediately after birth or in the first few hours or days of a child's life. It is characterized by a high mortality rate. ⋯ Surgical occlusion of CDH may in older children result in an improved vital capacity, as such cases are rarely associated with major pulmonary hypoplasia. Complications resulting from surgical treatment of CDH in older children are more likely to occur in the gastrointestinal system, as a consequence of the associated bowel malrotation and inadequate bowel fixation. Finally, these two cases corroborate the diagnostic value of accurate history taking and thorough physical examination.
