RESUMO
PURPOSE: The occurence of supraventricular arrhythmias associate with an unfavourable prognosis in septic shock. Propafenone could be a feasible antiarrhythmic. MATERIALS AND METHODS: Patients collected over a period of 24months were divided into the three groups based on antiarrhythmic: Group1(amiodarone), Group2(propafenone), Group3(metoprolol). Type of arrhythmia, cardioversion rates, demographic, haemodynamic, laboratory parameters were recorded in the first 24h. The outcome data were compared between the groups. RESULTS: 234 patients (99.1% ventilated) were included, the prevailing arrhythmia was acute onset atrial fibrillation (AF,69.7%). Except for the dosage of noradrenaline (0.35(0.14-0.78) in Group1(n=142)vs 0.25(0.10-0.50),p<0.01 in Group2(n=78)vs 0.14(0.07-0.25)µg/kg·min,p<0.05 in Group3(n=14)) the ejection fraction of left ventricle, rates of renal replacement therapy, arterial lactate and procalcitonin levels were not different between the groups. The cardioversion rate in Group1(74%) was lower than in Group2(89%) and Group3(92%). ICU and 28-day mortalities of Group1 were not significantly higher than in Group2 and Group3. Multivariate analysis demonstrated higher 12-month mortality in Group1 than in Group2 (HR1.58(1.04;2.38),p=0.03). CONCLUSIONS: Propafenone demonstrated a higher cardioversion rate than amiodarone with a similar impact on the outcome. Patients remaining in acute onset arrhythmia did not demonstrate significantly higher ICU, 28-day and 12-month mortalities compared to those successfully cardioverted or to those having chronic AF.

The authors present a case of massive lung bleeding following pulmonary endarterectomy (PEA) that was treated with peripheral veno-venous extracorporeal membrane oxygenation (VV ECMO). The patient repeatedly underwent bronchoscopy for airway blood clot obstruction and finally was successfully weaned off the support. The authors discuss the indications for ECMO in treatment of the most serious complications following PEA, and emphasize the importance of echocardiographic evaluation of the right ventricular function in relation to the indicated type of extracorporeal support. Anticoagulation strategy for patients shortly after the major surgery connected to ECMO is also discussed.
