Diabetic Foot Ulcers Clinical Trial
Official title:
The Effect of Combination Therapy of Oral Methylene Blue and Platelet-rich Plasma-fibrin Glue in Patients With Non-healing Diabetic Foot Ulcer: a Pilot Study
The aim of this study is to evaluate the chance of non-healing diabetic foot ulcers repair by improving the condition of lack of oxygen or hypoxia in the wound area caused by diabetes using methylene blue along with the use of platelet-rich plasma-fibrin glue as an effective treatment for wound healing.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | The healing rate of the ulcer | Measurement of wound area with a ruler | 4 weeks | |
Primary | Wound Size | Wound size will be measured with a ruler for length, and width as well as with digital imaging. Wound size will be assessed in digital images taken of the wound. | 4 weeks | |
Secondary | TcPO2 at baseline and after the intervention | Transcutaneous oxygen tension (TcpO2) provides information about blood perfusion in the tissue immediately below the skin. (blood pressure, measured in millimeters of mercury (mmHg)) | 4 weeks | |
Secondary | Oxygen saturation at baseline and after the intervention | Blood must contain a normal concentration of hemoglobin. that hemoglobin must be >95 % saturated with oxygen in arterial blood (sO2(a) >95 %) | 4 weeks | |
Secondary | Blood pressure (systolic and diastolic) | The pressure of the blood in the circulatory system | 4 weeks | |
Secondary | The resting systolic toe pressure (TP) at baseline and after the intervention | The toe cuff with the sphygmomanometer is slowly inflated until the waveform flattens (generally between 150-200 mmHg), then is inflated a further 20 mmHg.
