To evaluate early and late complications among victims exposed to indoor fire and smoke inhalation.
An observational, descriptive and prospective longitudinal study of 15 victims of smoke inhalation admitted to the intensive care unit.
Although without significant burns, 13 of the victims were unconscious, with airway injury, abnormal temperature and hypokalaemia, and underwent mechanical ventilation. Initial carbon monoxide concentration averaged 20.4+/-8.3%, dropping to 3.9+/-3.3% 4h later. On the 1st day, two victims recovered and were transferred, and another two died. Creatine kinase levels (2594+/-2455 U/l) correlated with duration of intensive care. Of the remaining 11 patients, 10 had early pneumonia. Steroid treatment was initiated for four patients receiving prolonged mechanical ventilation, because of persistent fever and dry cough without evidence of infection.
Mortality and systemic involvement were related to burn of the upper airway and contact with combustion products. Initial creatine kinase levels emerged as a prognostic marker of injury severity. Bronchoscopy was useful in grading airway injury and obtaining bronchoalveolar culture. Corticosteroids were effective, after the acute phase, in treating non-infectious pulmonary complications.
评估室内火灾烟雾吸入受害者的早期和晚期并发症。
对15名入住重症监护病房的烟雾吸入受害者进行观察性、描述性和前瞻性纵向研究。
尽管没有明显烧伤,但13名受害者昏迷,存在气道损伤、体温异常和低钾血症,并接受了机械通气。初始一氧化碳浓度平均为20.4±8.3%,4小时后降至3.9±3.3%。第1天,两名受害者康复并转出,另外两名死亡。肌酸激酶水平(2594±2455 U/l)与重症监护时间相关。其余11名患者中,10名发生早期肺炎。4名接受长时间机械通气的患者因持续发热和干咳且无感染证据而开始使用类固醇治疗。
死亡率和全身受累与上呼吸道烧伤及接触燃烧产物有关。初始肌酸激酶水平是损伤严重程度的预后标志物。支气管镜检查有助于气道损伤分级和获取支气管肺泡培养物。急性期后,皮质类固醇对治疗非感染性肺部并发症有效。
