This study compared the bronchial cuff pressures and volumes required by three different designs of disposable left double-lumen tubes during clinical one-lung ventilation in 48 patients having right thoracotomies. Mallinckrodt, Rusch, and Sheridan design tubes (n = 16 for each) were studied in a randomized fashion using Fr# 35, 37, 39, and 41 sizes (n = 12 for each size). There were no pressure/volume differences between brands during bronchial cuff inflation before endotracheal intubation. Intraoperatively, the Sheridan design required significantly higher mean bronchial cuff pressures: [27.9 cm H2O +/- 17 cm H2O (SD)] than either the Mallinckrodt [17.6 cm H2O +/- 8.5 cm H2O (P = 0.012)] or Rusch [14.1 cm H2O +/- 8.6 cm H2O (P = 0.010)] to achieve one-lung isolation. During prolonged one-lung ventilation, the potential for trauma to the bronchus may be reduced with a Mallinckrodt or Rusch design of left double-lumen tube.
本研究比较了48例行右胸切开术患者在临床单肺通气期间，三种不同设计的一次性左双腔管所需的支气管套囊压力和容量。采用随机方式研究了Mallinckrodt、Rusch和Sheridan设计的导管（每种各16例），使用了Fr# 35、37、39和41尺寸（每种尺寸各12例）。在气管插管前支气管套囊充气期间，各品牌之间的压力/容量无差异。术中，Sheridan设计的导管实现单肺隔离所需的平均支气管套囊压力显著高于Mallinckrodt [17.6 cm H2O +/- 8.5 cm H2O（P = 0.012）]或Rusch [14.1 cm H2O +/- 8.6 cm H2O（P = 0.010）]，分别为[（27.9 cm H2O +/- 17 cm H2O（标准差）]。在长时间单肺通气期间，使用Mallinckrodt或Rusch设计的左双腔管可能会降低支气管创伤的可能性。
