The cardiopulmonary performance levels in children who are convalescing from thermal injury are unknown. This investigation was designed to evaluate cardiopulmonary function in children with and without inhalation injury. Forty children with a mean time since burn injury of 2.6 +/- 1.9 years and a mean burn size of 44% +/- 22% total body surface area were selected for the study and divided into two groups: inhalation injury (group 1) and non-inhalation injury (group 2). Pulmonary function studies and cardiopulmonary stress testing were completed on all patients. Both groups reached the same endurance level on the treadmill; however, patients in group 1 did so with an increased expired volume, respiratory rate, and ratio of dead space ventilation to total ventilation which indicated that there were greater demands on the respiratory system. Spirometry and lung volumes at rest showed that 64% of patients in group 1 had abnormal lung function compared with only 27% of patients in group 2.
热损伤康复期儿童的心肺功能水平尚不清楚。本研究旨在评估有无吸入性损伤儿童的心肺功能。选取40名烧伤后平均时间为2.6±1.9年、平均烧伤面积为体表面积44%±22%的儿童进行研究，并分为两组：吸入性损伤组（第1组）和非吸入性损伤组（第2组）。对所有患者进行了肺功能研究和心肺应激测试。两组在跑步机上达到了相同的耐力水平；然而，第1组患者达到该水平时呼出量、呼吸频率以及死腔通气与总通气量之比增加，这表明呼吸系统的需求更大。静息状态下的肺活量测定和肺容积显示，第1组64%的患者肺功能异常，而第2组只有27%的患者肺功能异常。
