This study aimed to develop and assess the effectiveness of a protocol for antibiotic prophylaxis based on preoperative kidney function in patients undergoing open heart surgery.
We established a protocol for antibiotic prophylaxis based on preoperative kidney function in patients undergoing open heart surgery. This novel protocol was assessed by comparing patients undergoing open heart surgery before (control group; n = 30) and after its implementation (protocol group; n = 31) at Kyoto University Hospital between July 2012 and January 2013.
Surgical site infections (SSIs) were observed in 4 control group patients (13.3 %), whereas no SSIs were observed in the protocol group patients (P < 0.05). The total duration of antibiotic use decreased significantly from 80.7 ± 17.6 h (mean ± SD) in the control group to 55.5 ± 14.9 h in the protocol group (P < 0.05). Similarly, introduction of the protocol significantly decreased the total antibiotic dose used in the perioperative period (P < 0.05). Furthermore, antibiotic regimens were changed under suspicion of infection in 5 of 30 control group patients, whereas none of the protocol group patients required this additional change in the antibiotic regimen (P < 0.05).
Our novel antibiotic prophylaxis protocol based on preoperative kidney function effectively prevents SSIs in patients undergoing open heart surgery.
