Nam K, Park JB, Park WB, et al. - Via performing a retrospective, single center, before-and-after study, researchers here examined how subglottic secretion drainage during and after cardiac surgery affects postoperative ventilator-associated pneumonia (VAP). Among adult patients undergoing cardiac surgery from January 2013 to December 2018, use of conventional and subglottic suctioning endotracheal tubes was made in the control and intervention groups before and after a change in institutional policy, respectively. In the intervention group, patients underwent subglottic secretion drainage continuously during surgery and intermittently after surgery. Outcomes revealed that the risk of VAP, identified by the National Healthcare Safety Network surveillance definition algorithm, reduced after surgery in correlation with performing routine perioperative subglottic secretion drainage using subglottic suctioning endotracheal tubes in patients undergoing cardiac surgery.
