[Effect of fiberoptic bronchoscopy (FOB) with bronchoalveolar lavage (BAL) on gas exgange in patients after cardiac surgery].

Unlabelled: Fiberoptic bronchoscopy (FOB) has become a commonplace procedure in ICUs in patients after operation. We studied the outcomes of 35 FOBs performed in 26 patients (18 male and 8 female) during their stay in the ICU of "St. Ekaterina" University Hospital in Sofia after cardiac surgery with Cardiopulmonary Bypass.

[Rupture of the sinus of Valsalva--the anesthesiological and resuscitation problems].

The rupture of the sinus of Valsalva is a rare heart disease with a heavy clinical manifestation, the treatment of which is surgical. It is diagnosed with echocardiography and cardiac catheterisation. The anesthesiologist has to answer many and important questions about anesthetic treatment.

[Anesthesiological and resuscitation problems in the surgical treatment of acute massive pulmonary thromboembolisms].

Eleven patients operated on under extracorporal circulation (ECC) following acutely occurring massive pulmonary emboli were studied. The values of the following parameters were registered: pulmonary artery pressure, pulmonary capillary wedge pressure, intrapulmonary shunt and pulmonary vascular resistance. The measurements were carried out before the surgical procedure and in the postoperative period.

[A dynamic study of plasma fibronectin in patients undergoing heart operations under extracorporeal circulation].

In a preliminary analysis the level of plasma fibronective as well as the total protein and albumin were followed dup in cardiac patients. The dynamic changes of values of the parameters perioperatively and up to the 96-th postoperative hour were taken into consideration. The authors make the conclusion that the fibronectine reduction is not specific and reflects not so much the destruction of the heart muscle but the reparation processes following the surgical trauma.

[The dynamics of the more important indices of the external respiration following heart surgery operations].

A retrospective study comprising patients undergone cardiac surgery is done. In the study some measurable parameters of external breathing are followed up. The measurements are carried out by portable respiratory monitor.
