ABSTRACT
Objective To explore the clinical significance of combined detection of serum procalcitonin (PCT)and interleukin 6 (IL-6 )in patients with lower limbs long bone open fractures before and after emergency debridement fixation and postoperative reg-ular antibiotics treatment.Methods Patients with lower limbs long bone open fractures within 8-24 h after injury were divided in-to wounds fester group,wounds contamination group and wounds non-contamination group.Serum PCT and IL-6 levels were detec-ted and compared between patients group and control group.Results Before treatment,PCT and IL-6 levels in wounds contamina-tion group and wounds fester group were higher than control group (P0.05).After treatment,PCT and IL-6 levels in wounds fester group and wounds contamination group were decreased,but those in non-contamination group were with a trend of fluctuation.In the first day of treatment,PCT and IL-6 levels in contamination and fester group were higher than control group (P0.05).PCT and IL-6 levels in non-contamination group,compared with control group and levels before treatment,were not significantly different (P>0.05).In the third day of treatment,PCT and IL-6 levels in the three patient groups were higher than control group (P0.05).PCT and IL-6 levels in non-contamination group were significantly higher than the levels before treatment (P0.05). Conclusion Wounds infection could onset in patients combined with lower limbs long bone open fractures and soft tissue open inj u-ry.Dynamic monitoring of PCT and IL-6 levels might be significant for early prediction of bacteria infection,rational use of antibi-otics and promote healing of wounds and fractures.
