In a double-blind study with each patient as his own control, 1 g of cefazolin and 2 g of cephalothin were administered intravenously every 6 h to 20 patients in opposite arms for a period of 48 h each. The degree of phlebitis was significantly more severe with cephalothin than with cefazolin (P < 0.05); however, neither the incidence of phlebitis nor the time of onset of phlebitis was significantly different between the two drugs.
在一项以每位患者自身作为对照的双盲研究中,对20名患者的双臂分别每6小时静脉注射1克头孢唑林和2克头孢噻吩,各持续48小时。头孢噻吩所致静脉炎的严重程度显著高于头孢唑林(P<0.05);然而,两种药物的静脉炎发生率及静脉炎发作时间并无显著差异。
