Objective To investigate the surgical methods and clinical effect of repairing forefoot soft tissue defects with free peroneal artery perforator flap in elderly patients.Methods From June,2011 to April,2015,17 cases of forefoot soft tissue defects repaired with free peroneal artery perforator flap in elderly patients.There were 10 cases of male and female in 7 cases with an average age of 65.8 years old ranging from 60 to 74 years.Causes of injury:traffic accident in 7 cases,heavy crushing in 9 cases,electrical bums in 1 case.Injury part:6 cases on the left side and 11 cases on the right side.Metatarsus and phalanges fracture in 9 cases,tendon injury in 5 cases.Defect area:3.0 cm × 4.0 cm-6.3 cm × 11.2 cm.Results All flaps survived.All wounds were primary healing.Skin graft survived for the foot flap donor site,and no complicated with infection.All patients were followed up from 8 to 36 months with an average of 17.6 months.The appearance of flaps were good,slight bloated.The texture and color of the flaps were close to the recipient site.Flap feel were good.Accortling to (AOFAS)criteria system,the AOFAS score of last follow-up was (77.5±13.2).Excellent in 6 cases,good in 9 cases,fair in 2 cases.VAS score was (2.6±0.4).Conclusion The free peroneal artery perforator flap with the advantages of vascular anatomy constant,blood supply is reliable,thickness moderate,etc.It is a useful clinical method to repair forefoot soft tissue defects in elderly patients.

A closed-loop transfusion management system is constructed that covers blood preservation, transportation, transfer, distribution of blood, distribution, clinical blood specimen collection and blood transfusion process, which can monitor the implementation of doctor's advice, view the transport process of blood and blood samples, and record blood transfusion and adverse reaction information. These measurements can play a good effect in reduction of manual records and handover links in blood transfusion management, enhance the blood bank management, guarantee safely using blood, and realize the goal of real-time monitoring and closed-loop management.
