[Show abstract][Hide abstract] ABSTRACT: An 18-year-old male patient was admitted to our hospital because of a high impact trauma. A computed tomography scan showed massive mediastinal bleeding due to a posteriorly located rupture of the aortic arch with formation of a pseudoaneurysm. Although urgent repair was indicated, open cardiac surgery was not feasible, as this would involve full heparinization in a patient with subarachnoid bleeding. The chosen solution was to perform a percutaneous thoracic endovascular aneurysm repair (TEVAR) and a kissing chimney procedure using a U-shape configuration.
[Show abstract][Hide abstract] ABSTRACT: Despite their controversial role, corticosteroids (CS) are frequently administered to patients with H1N1 virus infection with severe respiratory failure secondary to viral pneumonia. We hypothesized that invasive pulmonary aspergillosis (IPA) is a frequent complication in critically ill patients with H1N1 virus infection and that CS may contribute to this complication.
We retrospectively selected all adult patients with confirmed H1N1 virus infection admitted to the intensive care unit (ICU) of two tertiary care hospitals from September 2009 to March 2011. Differences in baseline factors, risk factors, and outcome parameters were studied between patients with and without IPA.
Of 40 critically ill patients with confirmed H1N1, 9 (23 %) developed IPA 3 days after ICU admission. Five patients had proven and four had probable IPA. Significantly more IPA patients received CS within 7 days before ICU admission (78 versus 23 %, p = 0.002). IPA patients also received significantly higher doses of CS before ICU admission [hydrocortisone equivalent 800 (360-2,635) versus 0 (0-0) mg, p = 0.005]. On multivariate analysis, use of CS before ICU admission was independently associated with IPA [odds ratio (OR) 14.4 (2.0-101.6), p = 0.007].
IPA was diagnosed in 23 % of critically ill patients with H1N1 virus infection after a median of 3 days after ICU admission. Our data suggest that use of CS 7 days before ICU admission is an independent risk factor for fungal superinfection. These findings may have consequences for clinical practice as they point out the need for increased awareness of IPA, especially in those critically ill H1N1 patients already receiving CS.

[Show abstract][Hide abstract] ABSTRACT: Cibenzoline is an antiarrhythmic drug used to treat patients with supraventricular or ventricular arrhythmias. Cibenzoline overdose is associated with proarrhythmic and hemodynamic effects such as hypotension and congestive heart failure.
We report a case of cardiogenic shock due to cibenzoline overdose in a patient with progressive renal insufficiency.
The standard treatment of a cibenzoline intoxication is symptomatic, but we used combined hemoperfusion-hemodialysis to treat our patient.
This was associated with a rapid decline in plasma cibenzoline concentration and improvement of the clinical condition. However, only 28.98 mg of an estimated body pool of cibenzoline (447.2 to 806.6 mg) was removed during the 8 hours of treatment.

[Show abstract][Hide abstract] ABSTRACT: In this prospective, randomized, open controlled study we compared the effects on net red blood cell loss of 6% hydroxyethyl starch 130/0.4 (HES: n = 64) and 3% modified fluid gelatin (GEL: n = 68) administered for intravascular volume management in patients undergoing coronary surgery. Blood losses were calculated from determination of circulating blood volume and measurement of preoperative and postoperative hematocrit. Amount of colloids that could be administered was limited to 50 mL/kg. If additional fluids were required, balanced crystalloid solution was used. Anesthetic and surgical techniques were standardized. Both groups were similar with regard to demographic and intraoperative variables. Total study drug was 48.9 +/- 17.2 mL/kg in the HES group and 48.9 +/- 14.6 mL/kg in the GEL group. Total red blood cell loss was 544 +/- 305 mL in the HES group and 504 +/- 327 mL the GEL group. Measured blood losses were also similar in both groups (HES, 19.4 +/- 12.3 mL/kg; GEL, 19.2 +/- 14.5 mL/kg). Exposure to allogeneic blood product was comparable in both groups. In the conditions of the present study, HES 130/0.4 up to 50 mL/kg is a valuable alternative to modified fluid gelatin for plasma volume expansion during and after cardiac surgery.

[Show abstract][Hide abstract] ABSTRACT: Liberalization of stringent guidelines regarding donor selection is acceptable in the case of critical recipient condition. Few cardiac allografts with preexisting accessory atrioventricular pathways have been implanted. We describe the successful radiofrequency modification of the atrioventricular node and ablation of an accessory pathway after cardiac transplantation. Although the previously healthy donor had no history of arrhythmia, the recipient's postoperative course was characterized by multiple bouts of reentry tachycardia. The highly successful catheter-based ablation techniques available to cure this condition favor the use of donor hearts with a preexisting accessory pathway.
