title: Experience with pneumonia in acutely burned patients requiring ventilator support.
abstract: Acutely burned patients requiring ventilatory support who developed pneumonia while in the hospital were retrospectively reviewed. The Centers for Disease Control and Prevention (CDC) clinical criteria for pneumonia are based on clinical findings, radiographic findings, and culture data. During an 18-month period, 784 burn patients were admitted. Of these, 145 (18.5%) were placed on ventilators for at least 1 day. Fifty-three (36.6%) patients on ventilators developed acute pneumonia based on CDC criteria. Identification of causative organisms was based on positive cultures from blood or endotracheal aspiration within 3 days of the diagnosis of pneumonia. Thirty-nine patients were diagnosed as having inhalation injury. Forty-seven patients were placed on ventilators before or on the day of admission. Ages ranged from 2 to 82 years (mean, 39). Burn size ranged from 2 to 85 per cent (mean, 29.7%) of total body surface area. The total number of ventilator days was 1310 for the 53 patients, with a mean of 27.7 days. Ten patients had positive blood cultures during the period in which pneumonia was present. Thirty-one different organisms were recovered from blood or tracheal aspirates. The most commonly recovered organism was Pseudomonas aeruginosa. In 30 incidences, polymicrobial cultures were encountered. Initiation of appropriate antimicrobial therapy was begun on the basis of clinical impression and current burn unit experience and revised on the basis of the culture data. Of the 53 patients, 13 (25.5%) died, all while still on ventilators. The other 40 patients survived. Thirty-four were weaned off their ventilators, and 6 were transferred while still on ventilator support.
