abstract = "OBJECTIVE: Endotracheal suctioning can cause alveolar collapse and impede ventilation. One reason is the gas flow through a single-lumen endotracheal tube (ETT) provoking a gradient between airway opening and tracheal (P(tr)) pressures. Separately extending the patient tubing limbs of a suitable ventilator into the trachea via a double-lumen ETT should maintain P(tr). Can this technique reduce the side effects? DESIGN AND SETTING: Bench and animal studies in a university hospital laboratory. INTERVENTIONS: A lung model was ventilated via single and double-lumen ETTs. Closed-system suctioning was applied with catheters introduced into the single-lumen ETT or the expiratory lumen of the double-lumen ETT via swivel adapter. Seven anesthetized pigs (lungs lavaged) underwent three runs of ventilation and suctioning through (a, b) an 8.0-mm ID single-lumen ETT, (c) a double-lumen ETT (41Ch outer diameter, OD). In (a) the single-lumen ETT was disconnected for suctioning, in (b) and (c) ventilator mode was set to continuous positive airway pressure mode, and the ETTs remained connected. MEASUREMENTS AND RESULTS: Bench: Suction through single-lumen ETTs impaired ventilation and led to strongly negative P(tr) (common: -10 to -20 mbar); the double-lumen ETT technique maintained ventilation and pressures. Animals: Lung gas content (computed tomography, n=4) and arterial oxygen partial pressure, initially 1462+/-65 ml/532+/-76 mmHg, were significantly reduced by suctioning through single-lumen ETT: to 302+/-79 ml/62+/-6 mmHg with disconnection and to 851+/-211 ml/158+/-107 mmHg with closed suction. With double-lumen ETT they remained at 1377+/-95 ml/521+/-56 mmHg. CONCLUSIONS: The double-lumen ETT technique minimizes side effects of suctioning by maintaining P(tr).",
