E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Main objective of the trial is to verify whether the antibiotic administration algorithm for prophylactic use in thoracic surgery currently used at the Cardiac surgery department of the University Hospital in Hradec Králové is effective. Furthermore, the aim of this study is to find out whether systemic antibiotic administration reaches sufficient blood levels at the beggining of surgery and corresponds to therapeutic levels that always exceed the minimum inhibitory concentration (MIC).
|
Cílem studie je ověřit, zda je algoritmus podávání antibiotik k profylaktickým účelům u hrudní chirurgie zavedený v současné době na kardiochirurgické klinice FN HK efektivní. Dále je účelem této studie zjistit, zda systémové podání antibiotika dosahuje v krvi na začátku operace dostatečných hladin a odpovídá hodnotám terapeutických hladin vždy převyšujícím minimální inhibiční koncentraci (MIC). |
|
E.2.2 | Secondary objectives of the trial |
Secondary objective of this study is to find out whether repeated administration of antibiotics in the current regimen is abundant. |
Dalším cílem této studie je zjistit, zda není opakované podání antibiotika ve stávajícím režimu abundantní. |

E.5 End points |
E.5.1 | Primary end point(s) |
Parameters of cephalosporin efficacy are evaluated by monitoring the MIC break point (4 mg /l for MSSA). Efficacy parameters are defined by 20 times the level above the MIC of 4 mg/l. Blood levels of cephalosporins will be monitored and the level is expected higher than 350 mg/l after intravenous administrated dose 2 grams.
|
Parametry účinnosti cefalosporinů jsou vyhodnocovány monitorací break pointu MIC, který je nyní pro MSSA stanoven na 4 mg/l. Parametry účinnosti jsou vymezeny 20 násobkem hladiny nad MIC 4 mg/l. Dále bude sledována hladina cefalosporinů v krvi, kdy očekáváme při dávce 2 g i. v. hodnotu nad 350 mg/l.
