ABSTRACT
Objective To assess the effects of different administration timing of prophylactic antibiotics on infections after hip arthroplasty. Methods 535 patients having undergone arthroplasty were divided into two groups: the experiment group (n=273)and the control group (n=262): The former groupwere administered with antibiotics until 24 hours postoperatively and the latter until 72 hours postoperatively. The two groups were compared in terms of postoperative infection rate. Results The infection rates in the experimental groupand the control group were 4.396%and 3..817%, with insignificant differencebetween them. Conclusion For those patients undergoing hip arthroplasty, extended administration of antibiotics after operation (over 48 hours) may not reduce the risk of recent the infection rate.
