Noninvasive Ventilation After Coronary Artery Bypass Grafting in Subjects With Left-Ventricular Dysfunction.
BACKGROUND: The use of noninvasive ventilation in patients with left-ventricular dysfunction may increase cardiac performance by decreasing inspiratory effort and left-ventricular afterload. The aim of the present study was to evaluate the acute effects of noninvasive ventilation on centralvenous ox...

The aim of the present study was to evaluate the acute effects of noninvasive ventilation on centralvenous oxygen saturation (...) and blood lactate in subjects with left-ventricular dysfunction during the early postoperative phase of coronary artery bypass grafting. METHODS: This study included 100 subjects during the postoperative phase of elective coronary artery bypass grafting. Blood samples, at 5 time points, were collected to assess tissue perfusion markers (ie, ... and blood lactate) as follows: (1) the intraoperative period (after anesthesia induction); (2) 20 min after ICU arrival, under intermittent mandatory ventilation; (3) 20 min after extubation with spontaneous breathing; (4) after 1 h of noninvasive ventilation; and (5) 20 min after discontinuation of noninvasive ventilation. RESULTS: A significant increase in the blood lactate and a drop in the ... were observed on arrival to the ICU compared with intraoperative values (P < .001). After extubation, during spontaneous breathing, the ... significantly decreased (P = .02), whereas the blood lactate increased, although not significantly (P = .21) compared with intermittent mandatory ventilation on arrival to the ICU. During the application of noninvasive ventilation, the ... significantly increased (P = .048) and the blood lactate significantly decreased (P = .008) compared with spontaneous breathing values after extubation. After noninvasive ventilation discontinuation, the ... and blood lactate did not change compared with measures taken during noninvasive ventilation; higher values of ... were maintained compared with those obtained after extubation (P < .001). CONCLUSIONS: The acute application of noninvasive ventilation improved ... and decreased the blood lactate in subjects with left-ventricular dysfunction during the early postoperative phase after coronary artery bypass grafting. pubtype: Academic Journal doctype: research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
