Diabetic Foot Syndrome
DOI: Neuropathy, peripheral artery disease PAD , deformities of the foot related to motor neuropathy and minor foot trauma, infection and osteomyelitis are major threats relating to DFU. This article aims to summarize the current knowledge for the diagnosis and management of patients with DFUs and to increase the awareness of the treating physicians for their prevention, early diagnosis and prompt treatment.
Pathophysiology DFUs can be divided into neuropathic, ischaemic and neuro-ischaemic.
Sympathetic neuropathy results in reduced sweating, skin dryness with cracks and fissures, and increased blood flow to the foot with arteriovenous shunting. Musculoskeletal examination should include foot deformities, joint mobility, muscle wasting and presence of calluses. Common diabetic foot deformities are claw toes metatarsophalangeal joint hyperextension with interphalangeal flexion , hammer toes distal phalangeal extension , prominent metatarsal heads, pes cavus and Charcot arthropathy.
It should be tested over the tip of the hallux bilaterally. ABI is a measure of perfusion at the level of the foot; a portable Doppler ultrasound probe frequency range 5 to 8 MHz and sphygmomanometer cuff are used to measure systolic pressures on the arm, the ankle and pedal circulation posterior tibial, dorsalis pedis and, occasionally, peroneal arteries on both legs.
The ratio of the pressures in the distal circulation to the lower value obtained from the brachial arteries yields an ABI. Identifying tissue viability among patients with DFUs is important, given its association with failure to heal. In addition, failure to successfully determine the level of amputation adds the subsequent risk of perioperative cardiovascular events that can lead to death.
Standard Doppler arterial waveforms, ABI measurement, toe pressures, transcutaneous tissue oxygenation and thermal mapping have been traditionally used to potentially provide regional perfusion information and also to predict amputation levels.
Although all these techniques provide useful information in the assessment of tissue and foot perfusion there is no widely accepted standard for the evaluation of tissue microcirculation and the prediction of wound healing. Nephrogenic systemic fibrosis and exposure to radiation are the main limitations of CT and MR angiography in patients with impaired renal function.
DUS offers easy non-invasive two-dimensional 2D colour images and haemodynamic data using Doppler shift frequency analysis of the arterial tree to the level of the pedal vessels.
It is the easiest of vascular imaging modalities, though its availability may be limited by the expertise of the operator. There is very limited evidence that suggests that DUS is comparable with contrast angiography in planning clinical management.
A functional microcirculation is essential to maintain tissue viability. In current practice, non-invasive technology assessments of tissue viability may be achieved by measuring the TBI or transcutaneous oxygen tension TcPO2. TBI is measured using an optical sensor to detect arterial flow and a cuff connected to a sphygmomanometer in the same way as blood pressure is measured.
TcPO2 measurements are affected by capillary density and are influenced by oedema as well as skin thickness. Infection evaluation DFU infection should be recognized, classified and treated promptly. Prevention Diabetic foot ulcers can often be prevented by careful control of diabetes and proper foot care.
Diabetic Foot Infections
It is important to control blood sugar levels in order to prevent peripheral neuropathy or to stop it from worsening.
People with diabetes should check their feet, including the areas between the toes, daily for sores and cuts.
They should see a doctor immediately if a foot problem develops. Those who cannot see their feet can use a mirror on the floor or a long-handled mirror.
The feet, including the areas between the toes, should be kept clean and dry. People with diabetes should check the bath temperature with their hand.
Toenails should be carefully trimmed with the contour of the toe, and sharp nail edges should be filed smooth. People with peripheral neuropathy should not cut their own nails, and a clinician, such as a podiatrist doctor specializing in foot care , should evaluate them regularly. Footwear should fit properly to avoid friction or pressure.
People with peripheral neuropathy should avoid walking barefoot and should check their footwear for foreign objects before putting them on. Possible treatments Seek appropriate professional care at the first sign of a foot problem.
Avoid putting any pressure on the foot wound.Because this may result in the foot needing to be amputated, preventing ulcers is very important. Traditionally, the ankle brachial index ABI has Foot ulcers and amputations reduce the quality of life, increa This article aims to summarize the current knowledge for the diagnosis and management of patients with DFUs and to increase the awareness of the treating physicians for their prevention, early diagnosis and prompt treatment.
Another priority in diabetes research is the prevention of diabetic foot.
