Volume-time curve: an alternative for endotracheal tube cuff management.

摘要: BACKGROUND: Despite numerous studies on endotracheal tube cuff pressure (CP) management, the literature has yet to establish a technique capable of adequately filling with an appropriate volume air while generating low CP in less subjective way. The purpose this prospective study was evaluate and compare levels required fill tubes using 2 different techniques (volume-time curve versus minimal occlusive volume) immediate postoperative period after coronary artery bypass grafting. METHODS: A total 267 subjects were analyzed. After surgery, lungs ventilated controlled continuous mandatory ventilation, same ventilatory parameters adjusted. Upon arrival ICU, completely deflated re-inflated, at point adjusted one randomly selected techniques: volume-time volume. We measured injected into cuff, CP, expired tidal mechanical ventilation application each technique. RESULTS: demonstrated significantly lower compared (P < .001). Nosignificantdifferencewasobservedintheexpiredtidalvolumebetweenthe2techniques(P.052). However, when submitted technique, 17% (n 47) experienced leakage as observed by graph. CONCLUSIONS: associated Therefore, may be more reliable alternative for management. Key words: pressure; leakage; curve; technique; management; surgery.
