RESUMO
Fifteen patients with severe bacterial infection (12 with pneumonia) that developed in the resuscitation unit were subjected to the empirical monotherapy with piperacillin/tazobactam (P/T) or tazocin under an open randomized controlled experiment. P/T was administered intravenously in a dose of 4.5 g every 8 hours for 5 to 12 days (9.3 days on the average). When the monotherapy was not sufficiently efficient the patients were additionally treated with amikacin administered intravenously in a dose of 0.5 g every 8-12 hours. The favourable effect was observed in 14 patients (93 per cent). 7 of them were treated with P/T alone and 7 were treated with P/T in combination with amikacin. The primary pathogens were eradicated in 8 (73 per cent) out of the 11 patients treated with P/T alone. Before the treatment 34 microbial strains were isolated from the patients. 77 per cent of them were susceptible to P/T. The treatment with P/T resulted in eradication of 27 bacterial strains (79 per cent) including 67 per cent of gram-positive organisms and 86 per cent of gram-negative organisms. The adverse effects were recorded in 1 patient on the 6th day of the treatment: skin eruption and pruritus that required the treatment discontinuation. The results showed that the use of P/T in the initial empirical monotherapy of infections in patients under resuscitation conditions could be efficient.
