Short time effects of a low-frequency, high intensity magnetic field in the treatment of chronic neck and low back pain.

Introduction: Neck and back pain afflicts millions of people. Magnetotherapy has shown to have anti-inflammatory effects that could act on pain generation, but the literature lacks provide a precise therapeutic protocol. Methods: A high-intensity electromagnetic field with a dedicated applicator was administered to 38 patients with low-back pain and 30 patients with neck pain. The device provides 60 mT and a frequency of 50 Hz for 30 minutes, the session was repeated 4 times. Results: The mean VAS of the low-back pain group decreased from 6.56 to 4.54, with a significant reduction of 30.8%. The mean VAS of the neck pain group decreased from 6.51 to 1.96, with a significant reduction of 69.9%. Discussion: The treatment used showed good results in both groups of the patient, without side effects. The therapeutic protocol adopted is safe, provide rapid relief from the pain and is not time demanding. This treatment could represent an effective non-pharmacologic physical therapy option in the treatment of low-back pain and cervical pain.

Inguinal field block for femoral artery exposure during endovascular aneurysm repair.

PURPOSE: To analyze the feasibility and outcomes of an inguinal field block (IFB) for femoral artery exposure in patients undergoing elective endovascular aneurysm repair (EVAR). METHODS: Between January 2004 and June 2012, 784 patients (597 men; mean age 76 years) underwent elective EVAR via surgical cutdown to the common femoral arteries. The data from these procedures were retrospectively analyzed to determine the technical feasibility of IFB, need for conversion to general anesthesia, mortality, and complication rate. RESULTS: IFB was successfully performed in 768 (97.9%) patients. Conversion from IFB to general anesthesia was necessary in 11 (1.4%) patients owing to patient discomfort (n=3, 0.4%), anxiety (n=5, 0.6%), and persistent patient movement (n=3, 0.4%). The remaining 5 (0.7%) patients underwent EVAR under general anesthesia because they refused IFB. Technical success of EVAR was 99.7%; the mean operation time was 84 minutes and the radiation time was 13 minutes. The mean hospital stay was 3.7 days; no patient required intensive care. At 6 months, there were no reports of local/systemic complications related to IFB, such as infection, seroma, hematoma, nerve injury, or allergic/toxic reactions. CONCLUSION: Our study demonstrated that performing EVAR with femoral cutdown under IFB is a feasible, safe, and effective surgical and anesthetic combination, with very little need for conversion to general anesthesia.
