Plantar Pressure Reducing Effect of Diabetic Shoes with Different Rigid Rockers

OBJECTIVE: To determine the most effective type of rigid rocker bottom for prevention of diabetic foot complications according to the different rocker angles and axes of diabetic shoes. METHOD: Thirteen healthy volunteers participated in this study and the plantar peak pressure and pressure time integrals were measured by insole plantar pressure system for subjects either barefoot and wearing rigid rocker shoes with 12 kinds of different rocking angles and rocking points (15, 20, 25, 30degrees and 60, 65, 70% of shoe length). Evaluation was analyzed at M1 (hindfoot), M2 (midfoot), M3 (medial forefoot area), M4 (central forefoot area), M5 (lateral forefoot area), M6 (1st toe area), M7 (lesser toes area) zones respectively. RESULTS: Reduced pressure was observed in all kinds of rockers at central-metatarsal area (p<0.05). But pressure was not significantly changed at lateral metatarsal area in almost all types of rocker. With rocking point at 65 and 70%, pressure was increased at first and lesser toe area in all rocking angles. With rocking point at 60 and 70%, pressure was increased at midfoot area. CONCLUSION: Most effectively reduced pressure was observed with shoe of rocking point at 65% and rocking angle 30degress.

A Study on the Implementation of Medical Telemetry Systems Using Wireless Public Data Network Medical Telemetry System / 대한의료정보학회지

As information communication technology developed we could check our blood pressure, pulsation, electrocardiogram, saturation of arterial oxygen (Sa02) and serologic chemical tests easily at home. It is possible though interlocking the house medical instrument with the wireless public data network. Data from patients can be transmitted to the distant hospital and will be essentially applied through wireless public data network. In this study we measured electrocardiogram (ECG) for the telemetry. We put the EGG function into the movable device and add 900MHz band wireless public data interface, through which patients could record EGG and keep the data at home. We used wireless network modem and NCL (Native Gontrol Language) protocol to contact through wireless network, and 8CR (Standard Context Routing) protocol in the networkto connect to the wired host computer. The host computer checks the recorded individual EGG data and then sends the correspondant reply to the movable device. The study suggests the medical transmit system model utilized by the wireless public data network. The suggestion in the study of telemetry system provides movement and preservation. And it will exam the health condition in distance or at home.

Clinical Study for 20 Cases of Anesthesia for Total Replacement / 대한마취과학회지

We have experienced 20 cases of anesthesia for Total Hip Replacement(Charnleys Lov Frictinn Arthroplasty), which had been done under the Filtered Air Flow System for the prevention of wound contamination due to long term exposure. Preoperative diagnosis was, 7 cases of Hip Joint Tuberculosis, 6 cases of Femur Neck Fracture, 5 cases, of Osteoarthritis of Hip Joint, and 2 cases, of Avascular Necrosis. Average blood loss has 1500 ml for one side operation, and 2400 ml for bilateral one. In 12 cases, hypotensive response was occurred during the application of Acrylic bone cement to the medullary canal of femur, however in 4 cases, hypotensive responses was more prominentafter the application of Acrylic bone cement to the Acetabulum fossa and the rest of cases were no changes in blood pressure and pulse rate whatsoever. In two cases, hypotensive range was over 30%(in compare with preoperative one), but recovery was soon after administration of Effortil corticosteroids, volume expanders etc. There was no mortality.

Cushing's Syndrome due to Adrenocortical Carcinoma: Anesthetic Experience with Two Cases / 대한마취과학회지

Anesthetic experience with unilateral adrenalectomy for two patients (ll-year-old and 19- year-old female) with Cushings syndrome due to adrenocortical carcinoma has been reported. Anesthesia was induced with intravenous thiopental followed by nitrous oxide-oxygen-halothane and Pancuronium (Mioblock) for muscular relaxation. An endotracheal semi-closed circle absorption techniqne with controlled respiration was employed. The Patient tolerated well the anesthesia and surgery with appropriate cardiovascular control using hydrocortisone, whole blood and fluid replacement under continuous monitoring of B.P., E.C.G., C.V.P., and urine output. Importance of optimal preparation of the patient with Cushings syndrome, sufficient sedation, smooth induction, complete analgesia, good mucular relaxation, adequate alveolar ventilation and of proper cardiovascular control has been stressed and discussed together with the hazards of postoperative adrenal insufficiency.
