在粒细胞显著减少的患者,当发生细菌感染时,其治疗颇为困难。其减少的程度与感染发生的频率以及病情严重程度相关。粒细胞在1,000/mm~3以下时易发生感染,500/mm~3以下时多发生严重感染,100/mm~3以下极易发生致命的感染。作者在近3年内应用大剂量羧苄青霉素或并用其他抗菌素和丙种球 In patients with markedly reduced granulocytes, treatment is quite difficult when a bacterial infection occurs. The extent of this reduction is related to the frequency of the infection and the severity of the disease. Granulocytes in 1,000 / mm ~ 3 below prone to infection, more than 500 / mm ~ 3 when the most serious infections, 100 / mm ~ 3 following the most vulnerable to fatal infections. The authors applied high-dose carbenicillin in combination with other antibiotics and gamma bulbs in the last three years
