RESUMO
In a effect to prevent nosocomial pneumonia and sepsis, we treated patients with severe multiple trauma with an immunomodulator--beta 1-3 polyglucose (glucan). Forty-one patients with no infection at admission were stratified using Trauma Score and included in a randomized double-blind controlled trial. They were divided into a control group (n = 20) and a glucan group (n = 21). Pneumonia occurred in 11 of 20 patients in the control group and in two of 21 recipients of glucan (p < 0.01). Sepsis occurred in seven of 20 patients in the control group and in two of 21 patients treated with glucan (p < 0.05). Considering patients with pneumonia and sepsis, a decrease was observed in nosocomial infection from 65.0 to 14.4 percent (p < 0.001). The mortality rate related to infection was 30.0 percent in patients in the control group and 4.8 percent in the group treated with glucan (p < 0.05). The general mortality rate, cerebral deaths excluded, was 42.1 percent in the control group and 23.5 percent in the glucan group.
