Morphometric analysis of the lungs and heart of a male infant who died at 33 months of age of bronchopulmonary dysplasia after prematurity and respiratory distress syndrome and its treatment is presented. Alveolar internal surface area was 8.4 m2 compared to 15.3-27.8 for age-matched controls. The number of alveoli was 19 x 10(6) (123.3-172.5 x 10(6) for controls); however, the mean small airway diameter, 0.44 mm was normal, and small airway abnormalities were minimal. There was marked muscular hypertrophy of the right ventricle.
本文介绍了一名33个月大男婴的肺和心脏的形态计量学分析。该男婴早产并患有呼吸窘迫综合征，之后死于支气管肺发育不良。其肺泡内表面积为8.4平方米，而年龄匹配的对照组为15.3 - 27.8平方米。肺泡数量为19×10⁶（对照组为123.3 - 172.5×10⁶）；然而，平均小气道直径0.44毫米是正常的，小气道异常极少。右心室有明显的肌肉肥大。
