Peripheral Nerve Stimulation in Diabetic Patients

Diabetic Polyneuropathy

The prevalence of diabetes mellitus (DM) in industrialized countries is estimated to be about 7.3% and its incidence has been growing in recent years. The prevalence of diabetic neuropathy in the diabetic patient population is up to 50%. When limb surgery is necessary, it is reasonable to assume that diabetic patients will benefit from a peripheral regional anesthesia because of the severe comorbidities associated with DM. On the other hand, the use of regional anesthesia (RA) has generally not been recommended in patients with preexisting neuropathies mainly because of medical liability issues, as worsening neuropathy could be attributed to nerve damage caused by the regional anesthetic. The current state of the art of peripheral regional anesthesia for the identification of correct placement of an injection needle suitably close to the target nerve is to elicit a motor response by current injection through the needle. Constant reduction of the current as the nerve is approached ensures close proximity so that an effective nerve block is obtained when the local anesthetic is delivered through the needle, and absence of a motor response at 0.3 mA is generally accepted as a safety marker to avoid harmful intraneural injection. An important deficit in our understanding is whether diabetic neuropathy influences the stimulation parameters for peripheral nerve stimulation (PNS), possibly decreasing safety. The currently proposed research is guided by the hypothesis that nerves in patients with DM are more resistant to stimulation and the current thresholds for PNS have to be set much higher to prevent injections from occurring within the epineurium. The investigators will examine the effect of DM on nerve excitability in a blinded, prospective, observational case control trial. Accordingly, the investigators have defined following aims: Specific Aim 1: To characterize the required stimulation current in patients with and without diabetes mellitus. Specific Aim 2: Follow-up to examine if the rate of adverse neurologic events is higher in diabetic patients. Specific Aim 3: Guided by the results, formulate recommendations for the performance of regional anesthesia in patients with a history of DM. These experiments will provide better understanding of the needle-current-nerve relationship during peripheral nerve stimulation. Findings from this study will have a major impact on patient safety, especially in the subgroup with preexisting neuropathy, undergoing regional anesthesia.

Diabetic Foot UlcerDiabetic Neuropathy Peripheral

This study evaluates the effects of a physiotherapy protocol (manual therapy and exercise) in the prevention of diabetic foot ulcers in patients with diabetic neuropathy. A group of participants will receive a physiotherapy protocol added to their usual medical treatment and the other group will not receive physiotherapy treatment.

Magnetic Resonance Diagnostics of Diabetic Peripheral Neuropathy

Diabetes MellitusType 18 more

This project aims to develop high field MR techniques to detect nerve lesions in diabetic patients. The MRI findings will be compared to results from conventional evaluations and nerve conduction studies to determine the validity as part of a clinical practice.

In Vivo Corneal Confocal Microscopy for Non-invasive Assessment of Diabetic Peripheral Neuropathy...

Diabetic Peripheral Neuropathy

Clinical in vivo confocal microscopy (IVCM) is a relatively new technique of corneal evaluation that permits non-invasive imaging of corneal structures on the cellular level. Precise anatomic characterization of corneal structures, including corneal nerves, can be rapidly performed with high resolution.

Cardiovascular Autonomic NeuropathyDiabetic Autonomic Neuropathy1 more

The purpose of this study is to measure the prevalence and severity of cardiac autonomic neuropathy (CAN), diabetic autonomic neuropathy (DAN) which in non-diabetics is termed advanced nervous system (ANS) dysfunction, and autonomic dysfunction as well as the overall sympathovagal balance (SB) in the CEFH population of diabetic patients versus non-diabetic patients undergoing elective vitreoretinal surgery.

Thermal Screening for Early Diabetic Peripheral Neuropathy (DPN)

Diabetic NeuropathiesDiabetic Foot1 more

The goal of this research is to develop better tools for diagnosing illness of the feet and legs of people who have diabetes. Investigators will use thermal videos of the foot to aid in the refinement of a system designed to detect signs of diabetic peripheral neuropathy (DPN). The team of investigators will also look at diabetic eye disease and how it might relate to diabetic foot disease.
