Repeated tracheal aspiration was highly productive and showed hemoptysis and sustained intraalveolar plasma leakage.
Initially, participants were mechanically ventilated in the volume-induced mode, with a tidal volume of 8 ml per kilogram of body weight, inspiratory flow of 60 litres per minute (square wave), with hyperinflated cuff, positioned in a supine 30-degree head-up position, and underwent tracheal aspiration. Inspiratory oxygen fraction and positive end-expiratory pressure remained unchanged.
Barium swallow examination revealed tracheal aspiration, and gastroesophageal reflux was later confirmed with a milk scan.
