E.5 End points |
E.5.1 | Primary end point(s) |
Quantification of cefoxitin blood levels, through samples collected after anesthesia induction. Blood draws are to be taken at skin incision (approximately one hour after cefoxitin bolus), 15 minutes after CPB start (CPB1), at the end of CPB (CPB2) and at the end of surgery. |
Quantificazione dei livelli ematici cefoxitina, attraverso campioni raccolti dopo l'induzione dell'anestesia. I campioni di sangue seriati verranno prelevati in concomitanza dell’incisione cutanea (circa un'ora dopo il bolo di cefoxitina), 15 minuti dopo la procedura chirurgica mediante CPB (CPB1), alla fine della procedura chirurgica mediante CPB (CPb2) e alla fine dell'intervento. Al termine della CPB verrà effettuato un prelievo di ultrafiltrato dalla sacca di raccolta |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The day of prophylactic therapy coincides with the day of the surgical procedure |
Il giorno della terapia profilattica coincidente con il giorno della procedura chirurgica |
|
E.5.2 | Secondary end point(s) |
To compare peak and through values in neonates, infants, children weighting less than 40 kg and children weighting more than 40 kg
To evaluate the impact of CPB volume with respect of patients’ body weight, including the amount of fluids (crystalloids, colloids and hemoderivatives) administered intraoperatively to studied patients, on the enrolled patients
The incidence of post-operative infections in the studied population with particular attention to sensitive bacteria (including methicillin resistant staphylococcus aureus) will be recorded throughout patients’ PCICU admission.
The concentration of cefoxitin in the ultrafiltrate (UF) and their total removal will be evaluated at the end of CPB (UF1) from the total UF volume. The UF volume will be specifically recorded. Antibiotic’s sieving coefficient (SC) will be calculated as UF1/[(CPB1+CPB2)/2]. Antibiotic clearance will be calculated as SC*UF rate (ml/min).Evaluation of adverse events (serious and non-serious) and adverse drug reactions throughout the duration of trial by assessment of physical examination, vital signs, 12-lead electrocardiogram. Serious and non-serious adverse events will be collected intra-operatively. |
Confrontare i livelli plasmatici di cefoxitina nei neonati, bambini di peso inferiore a 40 kg e bambini di peso superiore a 40 kg.
Valutare l'impatto del volume del CPB rispetto al peso corporeo del paziente, compresa la quantità di liquidi (cristalloidi, colloidi e emoderivati), somministrato durante l'intervento per i arruolati
Valutare l'incidenza di infezioni post-operatorie nella popolazione studiata con particolare attenzione ai batteri sensibili (compresi resistente alla meticillina Staphylococcus aureus)
Determinare la concentrazione di cefoxitin nell'ultrafiltrato (UF) e la sua eliminazione totale, alla fine del CPB (UF1), dal volume totale UF. Il volume UF sarà specificamente registrato. Il Coefficiente di sieving dell’antibiotico (SC) sarà calcolato come UF1 / [(+ CPB1 CPb2) / 2]. La clearance dell’antibiotico sarà calcolata come SC * tasso di UF (ml / min) .
Valutare gli eventi avversi (gravi e non gravi) e le reazioni avverse per tutta la durata dello studio attraverso la valutazione dei parametri fisici, dei segni vitali, dell'elettrocardiogramma.
