title: Postoperative infections after major heart surgery and prevention of ventilator-associated pneumonia: a one-day European prevalence study (ESGNI-008).
abstract: Few data have been published on the prevalence of postoperative infection in patients undergoing major heart surgery (MHS). The degree of compliance with standard measures used to prevent them is unknown. This study assessed the prevalence of infections, particularly ventilator-associated pneumonia (VAP), in patients undergoing MHS in 42 institutions from 13 European countries. On the study day, there were 321 postoperative MHS patients, of whom 164 (51%) were mechanically ventilated. The overall prevalence of infection was 26.8%. Lower respiratory tract infections represented 57% of all the infections present on the study day. Other infections included intravenous-catheter-related bloodstream infections (2.8%), surgical site infections (2.2%), urinary tract infections (0.9%) and postoperative mediastinitis (0.9%). Of the mechanically ventilated patients, 55 (33.5%) were not being nursed in a semi-recumbent position, 36 (22%) had heat-moisture exchangers with no antibacterial filters, and intracuff pressure was not monitored in 78 patients (47.6%). Only 13 patients (8%) were given continuous subglottic suctioning, 64 patients (39%) did not receive postural oscillation, and gastric overdistension was not actively prevented in 23 patients (14%). In conclusion, these data from intensive care units across Europe provide information on postoperative infections in an important subset of the patient population, and stress the need for active interventions to prevent VAP in patients undergoing MHS.
