“…When adequate C‐fibre activity is present, the oxygen tension will be higher than when there is reduced C‐fibre activity (15). In support of this proposition, skin oxygen tension correlates well with healing rates (34–36). When sensors are at 39°C, the measured oxygen tension reflects basal oxygen tension (15).…”

A new therapy using sensory nerve stimulation [International Patent Application Number PCT/AU2004/001079: "nerve function and tissue healing" (Khalil, Z)] has been developed in our vascular physiology laboratory. This treatment has been found to improve the deficient sensory nerve function and associated deficient wound healing of older persons to levels seen in young people. An 82-year-old man with a small but persistent venous leg ulcer for 18 months, despite apparently appropriate wound dressings and compression therapy, was seen in a specialist wound management service. The patient's sensory and microvascular function was assessed in great detail using the vascular physiology laboratory techniques, and he was provided the sensory nerve stimulation therapy in addition to conventional therapy. His wound healed after 4 weeks. We report the case here. Prior to nerve stimulation therapy, cutaneous sensation, microvascular blood flow and oxygen tension were found to be reduced near the ulcer when compared with the opposite, non ulcerated leg. After therapy, oxygen tension and microvascular blood flow had improved. This case provides further evidence that sensory nerve stimulation therapy at the stipulated parameters improves wound healing. The observation that sensory nerve function improved provides support for the notion that improvement in healing is mediated by improved nerve function.

“…[24][25][26] Several studies show that an increase in transcutaneous oxygen of 10 mm Hg while breathing 100% oxygen in a hyperbaric chamber can also be used as a predictive value for amputation healing. [27][28][29] If these parameters are not met, a vascular referral is warranted.…”

It is estimated that approximately 23.6 million people in the United States have diabetes mellitus. With adequate control of this disease and appropriate foot care and basic surveillance, many patients can lead active and healthy lifestyles. However, some patients experience complications associated with poorly controlled glucose levels, including lower-extremity ulcerations and infections. When conservative measures have failed in treating these conditions, a lower-extremity amputation is an option for patients seeking to gain maximal functional recovery. A complete preoperative workup includes assessment of healing potential and preoperative ambulatory status, control or optimization of comorbidities when possible, and determination of amputation level using modern diagnostic modalities. Once the decision to proceed with an amputation has been made, it is important to choose an appropriate level of amputation and practice sound surgical technique. This article describes the preoperative evaluation and operative techniques involved in performing amputations on diabetic patients and reviews the current literature on the most common lower-extremity amputations performed in the care of infections in the feet of patients with diabetes mellitus.

“…Therefore, it can give false readings unless the influence of direct pressure on to the electrode is diffused over a larger area. Moreover, there is some difficulty in attaching any importance to low tcPO 2 values (0 -35 mmHg), as this does not preclude tissue survival [48] at the site of measurement.…”

Pressure ulcers cause great pain and suffering to patients as well as unnecessary strain on nursing staff. Their treatment is both costly and time consuming. Every effort therefore should be directed towards their prevention. Understanding of the aetiology of pressure ulcers is still incomplete and assessment of devices aimed at prevention is difficult. Over the years, numerous parameters, including interface pressure and transcutaneous blood gas measurements, have been used to evaluate mattresses and cushions. However, the quality of the data gathered is variable and its clinical interpretation remains unsatisfactory. It could be said that the science of evaluation of support surfaces is still at a formative stage, as clinical validation of many of the approaches has yet to be carried out.
