title: Relative incidence of phlebitis caused by continuous intravenous infusion of cephapirin and cephalothin.
abstract: In a single-blinded study, two groups of 10 healthy subjects were given cephapirin or cephalothin by continuous intravenous infusion for 5 days, 0.5 g every 6 hr for the first day and then 1.0 g every 6 hr for 4 days. Eight of the cephalothin subjects and two of the cephapirin subjects developed phlebitis. Phlebitis was more severe in the cephalothin group and developed more rapidly, necessitating vein changes six times more often than in the cephapirin group. The less irritating properties of cephapirin demonstrated in this study indicate it may be the more useful cephalosporin analogue for intravenous therapy.
