[Clinical study on the early and short -- term use of antibiotics with broad spectrum in severely burned patients].

OBJECTIVE

To investigate the prevention and treatment effects of early and short -- term use of antibiotics with broad spectrum on postburn severe infection in severely burned patients.

METHODS

Thirty -- five burn patients with TBSA from 50% to 95% were enrolled in the study. The patients were divided into early prevention [20 cases, antibiotics were used started from 6 postburn hours (PBH)] and delayed prevention (15 cases, antibiotics were applied after 48 PBH) groups. Plasma levels of LPS, TNFa and IL -- 8 were dynamically monitored with the concomitant observation of clinical signs of postburn sepsis.

RESULTS

After major burns, the plasma levels of LPS, TNFalpha and IL -- 8 increased evidently and reached the peak values on 3 similar 5 postburn days (PBD). But the levels of all above factors in the early group were obviously lower than those in the delayed group (P < 0.05 similar 0.01). The incidencies of sepsis and internal organ complications within 2 postburn weeks were much lower in the early group than those in the delayed group (P < 0.05). The subeschar bacterial quantification on 4 similar 7 PBD was evidently lower in the early group than that in the delayed group (P < 0.01).

CONCLUSION

Early and short -- term use of antibiotics with broad spectrum in severely burned patients could effectively prevent postburn severe infection and lower down the incidence of internal organ complications.
