摘　　要：目的探讨长期机械通气对食管面积变化的影响。方法选择62例机械通气患者,按机械通气时间分为短期机械通气(SMV)组和长期机械通气(PMV)组。比较两组患者机械通气脱机当日胸部CT影像图片上胸骨柄及气管分叉后食管面积。对所有患者的机械通气时间与食管面积进行相关性分析。结果PMV组患者的胸骨柄处及气管分叉处食管面积明显大于SMV组(Z分别=-5.91、-3.10,P均<0.05)。所有患者的胸骨柄处及气管分叉处食管面积与机械通气时间有明显相关性(r分别=0.91、0.58,P均<0.05)。结论长期机械通气患者的胸骨柄及气管分叉后食管面积明显增加。Objective To explore the correlation between esophageal cross-sectional area and long-term mechanical ventilation.Methods Totally 62 patients with mechanical ventilation were included and divided into a short-term mechanical ventilation group whose ventilation time shorter than 21 days but longer than 7 days and a long-term mechanical ventilation group whose ventilation time longer than 21 days.The areas of the esophagus behind the manubrium and tracheal bifurcation were compared between the two groups.The correlation between ventilation time and esophageal area was analyzed.Results In the long-term mechanical ventilation group,the esophageal areas behind the manubrium and tracheal bifurcation were larger than those in the short-term mechanical ventilation group(Z=-5.91,-3.10,P<0.05).Correlation analysis showed that the esophageal areas were positively related with the ventilation time(r=0.91,0.58,P<0.05).Conclusion The areas of the esophagus behind the manubrium and tracheal bifurcation is significantly larger in patients with long-term mechanical ventilation,which is correlated with the duration of ventilation.
