Management of complicated postoperative air-leak - a new indication for the Asherman chest seal.
Postoperative air-leak is a problem which is frequently encountered in thoracic surgery. We describe the utility of the Asherman chest seal, a device used in primary trauma care in the successful management of a complicated postoperative air-leak. The Asherman Chest Seal is a sterile occlusive dressing with a one-way Heimlich valve for treating open pneumothorax in acute settings. ⋯ All six patients had satisfactory expansion of the lungs with cessation of the air-leak. This was achieved without the pain and morbidity of a chest drain and inpatient stay. The Asherman chest seal is a simple but very useful device that has a role in management of complex air-leaks.

Nosocomial infections after off-pump coronary artery bypass surgery: frequency, characteristics, and risk factors.
We evaluated the frequency, risk factors, and characteristics of infections in 360 patients after off-pump coronary artery bypass grafting (OPCABG). A prospective study was performed during the period June 2004-October 2005 at Henry Dunant Hospital, Athens, Greece. C-reactive protein (CRP) and procalcitonin were assayed from 222 patients preoperatively, and 1-3 days following OPCABG. ⋯ The mean increase of CRP and procalcitonin levels in the first two or three days, respectively, after surgery was significantly higher (P<0.05) in patients with infection. Independent risk factors of infection (P<0.05) were history of major nervous system disorder, left ventricular heart failure preoperatively, emergent operation, transfusions of red blood cells during ICU stay, and duration of central venous catheter placement. The identification of risk factors for infection in combination with the appropriate evaluation of the increased CRP and procalcitonin values may help clinicians for the early diagnosis of infection after OPCABG.

Arginine vasopressin is an ideal drug after cardiac surgery for the management of low systemic vascular resistant hypotension concomitant with pulmonary hypertension.
Low systemic vascular resistance (SVR) hypotension concomitant with pulmonary hypertension (PH) is difficult to manage postoperatively because they are often catecholamine-resistant. So, we applied arginine vasopressin (AVP), which is a potent vasoconstrictor in a specific condition, for post-cardiotomy refractory low SVR hypotension concomitant with PH. We treated nine cases of postoperative refractory vasodilatory hypotension concomitant with PH even after conventional treatment that included nitric oxide inhalation and/or intraaortic balloon pump. ⋯ AVP improved systemic circulation (increased systemic blood pressure with maintaining cardiac output) without deterioration of pulmonary hypertension. AVP is an ideal drug for treating refractory low SVR hypotension concomitant with PH. But its indication must be limited.

Case ReportsSuccessful interventional closure of a patent foramen ovale in a pediatric patient supported with a biventricular assist device.
We report on a 16-year-old boy after an event of cardiac arrest and initial treatment with a veno-arterial extracorporeal membrane oxygenator (ECMO). After a short stabilisation period a biventricular assist device (BVAD, Thoratec) was implanted. Although the BVAD was functioning well, the patient showed persisting hypoxemia. ⋯ PFO has to be considered as a cause of arterial hypoxemia in patients supported with ventricular assist devices. The diagnosis of a PFO may be missed under ECMO-treatment. Interventional closure of a PFO can successfully be performed even if the patient is supported with a BVAD.

Effect of preoperative mild renal dysfunction on mortality and morbidity following valve cardiac surgery.
The objective of this study was to investigate the effect of preoperative mild renal dysfunction (RD) not requiring dialysis on mortality and morbidity after valve cardiac surgery (VCS). We studied 681 consecutive patients (2002-2006) who underwent valve cardiac surgery with or without coronary artery bypass graft (CABG). Preoperative RD was calculated with the abbreviated Modification of Diet in Renal Disease formula and was defined as a glomerular filtration rate <60 ml/min/1.73 m(2). ⋯ Preoperative RD was significantly and independently associated with more red blood cell transfusions and longer hospital stay (median 9 vs. 8 days, P<0.001). Mortality was similar in both groups (3.4% vs. 2.3%, P=0.43). Preoperative mild renal dysfunction in patients undergoing cardiac valve surgery is an independent marker of postoperative morbidity.
