Filter by:Foot surgery is a painful surgery that is usually scheduled in outpatients. A good management of analgesia is the crucial point. Regional anesthesia (RA) is the gold standard, that provides good anesthesia and a long duration of analgesia. The sciatic nerve block (or its branches) is the most adapted analgesic technique. Limitation of proximal sciatic block is the motor block of the ankle and results in the impossibility, for the patient, to walk during the early post-operative period. Distal block of the sciatic nerve (tibial and fibular nerve blocks), at the level of the ankle, has been proposed to maintain the mobility of the ankle, to make deambulation with crutches easier. Nevertheless, the lack of sensibility of the heel remains a limitation for early walking, even with adapted shoes (ie : Barouk). A specific anesthesia of the distal part of the foot, respecting the heel, could be the best option to provide an early deambulation and a suitable analgesia. Ultrasound identification and specific anesthesia of the branches supplying the distal part of the foot (medial and lateral plantar nerves) could meet this dual objective : good anesthesia and suitable analgesia for early deambulation. This study is a feasibility study of a specific block of the plantar branches of the tibial nerve, to preserve the sensibility of the heel, in case of foot surgery. The safety of the procedure will be assessed according to the rate of postoperative dysesthesia.
Foot ulcers develop in diabetics with neuropathy because of cumulative injury over the course of several days. These patients do not feel pain, and do not recognize their foot is being injured until a wound develops. Areas about to ulcerate become inflamed and “hot spots” can be identified. This study’s purpose is to evaluate the effectiveness of a home infrared temperature probe designed to forewarn patients that an area on the foot is inflamed so they can take preventive measures. The study will evaluate the incidence of diabetic foot ulcers among high-risk patients, evaluate the cost of home temperature monitoring compared to standard therapy, and evaluate patient satisfaction. 180 diabetics at high-risk of having foot complications will be randomized into 3 treatment arms: 1) standard therapy consisting of regular foot care; 2) standard therapy plus recording of a structured foot evaluation using a hand mirror; and 3) standard therapy plus infrared home temperature assessment to identify “hot spots.” Device patients will measure temperatures at 6 sites on the foot each day. When temperatures are elevated >4°F patients will contact the research nurse and decrease activity. The primary study outcome will be incident foot ulcers and Charcot fractures.
