119 구급대원들이 사용하는 현장 검사 장비 중 하나인 자가 혈당측정기는 결과 값이 정확해야 환자에게 적절한 처치를 제공할 수 있다. 연구 최초 조사 시점 이후 현재까지도 119 구급대원 현장업무 지침에 현장 검사 장비의 작동 유무, 수량 등을 확인하는 것은 있으나, 장비의 점검에 수량, 작동 여부 등은 있으나 본 연구에서 분석한 정도관리 내용은 없다. 현장검사 장비의 질 관리가 되지 않고 있다는 것은 환자에 대한 부정확한 평가와 이로 인한 불필요한 처치와 과소, 과대처치 또는 환자 상태가 악화될 가능성을 높일 수 있다. 본 연구를 통해, 앞으로 119 구급대원의 혈당측정기를 포함한 모든 현장검사 장비의 사용실태조사가 이루어져야 하고, 119 구급대 현장 업무 지침에 현장 검사 장비 정도관리를 추가하여야 하겠다. 또한, 현장 검사 장비가 관련 지침에 따라서 적절한 질 관리가 이루어져야 하고, 지역에서 관련 업무 전문가나 응급의료지도를 담당하고 있는 지도의사에게 관리되는 것이 합당하겠다.

Recent technical advancement allows noninvasive measurement of blood glucose. In this literature, we reviewed various noninvasive techniques for measuring glucose concentration. Optical or electrical methods have been investigated. Optical techniques include near-infrared spectroscopy, Raman spectroscopy, optical coherence technique, polarization, fluorescence, occlusion spectroscopy, and photoacoustic spectroscopy. Electrical methods include reverse iontophoresis, impedance spectroscopy, and electromagnetic sensing. Ultrasound, detection from breath, or fluid harvesting technique can be used to measure blood glucose level. Combination of various methods is also promising. Although there are many interesting and promising technologies and devices, there need further researches until a commercially available non-invasive glucometer is popular.

Blood glucose curves in the management for diabetic patients have several limitations including intermittent assessment of blood glucose concentration, hospitalization, patient restraint, and repeated phlebotomy. The aim of this study was to apply and evaluate a wireless continuous glucose monitoring system (CGMS) in healthy dogs. Subcutaneous interstitial glucose concentrations in 7 dogs were continuously monitored and recorded by wireless CGMS. During induced hyperglycemia, the interstitial glucose concentrations were compared with whole blood glucose concentrations measured by glucometer and serum glucose concentrations measured by automated chemistry analyzer, respectively. There were no significant differences among interstitial, whole blood and serum glucose concentrations. The interstitial glucose concentrations had a good correlation to serum glucose concentrations. The real-time wireless CGMS is a valuable tool for monitoring system of glucose concentrations in dogs. Use of the CGMS for diabetic patients will provide accurate information over traditional blood glucose curves.

Purpose: The purpose of this study was to investigate differences between a pulmonary aspiration group and a non-pulmonary aspiration group in glucose concentration of tracheal secretions by measuring time and feeding methods. Method: The subjects were 36 ICU patients who were receiving formula via nasogastric tubes and had endotracheal tubes or tracheostomy tubes. Tracheal secretions were collected by connecting suction traps to a suction catheter in three different times(within 1 hour after feeding, between 1 to 2 hours after feeding, and between 2 to 3 hours after feeding) for 2 days, overall six times. Glucose concentration of tracheal secretions was measured with the glucometer(Accucheck II). Results: Glucose concentration of tracheal secretions increased in progression after feeding. The mean of specimens collected last(between two to three hours after feeding) was shown to be the highest value(M=61.61mg/dl) in the pulmonary aspiration group. Significantly(p=.000) more subjects(94.44%) in the pulmonary aspiration group received formula via a 50cc syringe than those in the non-pulmonary aspiration group(22.22%). Conclusion: Critically ill patients may need more time for head-elevation after tube feeding to prevent pulmonary aspiration. In practice, enteral formula should not be given the patients via a $50_cc$ syringe anymore, instead a feeding bag or infusion pump should be used to prevent pulmonary aspiration.

Objective: The purpose of this study is to investigate the elevated blood glucose levels in the postoperative period are associated with an increased risk of deep wound infection in diabetic individuals undergoing lumbar spine surgery. Methods: Of 2896 patients who underwent lumbar spine operations by one surgeon between 1993 and 2002, 329(11.4%) were diabetics. The rate of deep wound infections in diabetic patients was 6.4%, versus 3.2% for nondiabetics. 152 patients had their operation before implementation of the protocol and 177 after implementation. Charts of the diabetic patients were reviewed. Mean blood glucose levels were calculated from documented results of finger-stick glucometer testing. Results: Twenty-one diabetic patients suffered deep wound infection. Infected diabetic patients had a higher mean blood glucose level through the first 2 postoperative days than noninfected patients($230{\pm}6.9$ versus $175{\pm}3.8mg/dL$; p<0.003) and had a long operation time($216{\pm}57.9$ versus $167.5{\pm}42.2$ minute; p<0.05). Multivariable logistic regression showed that mean blood glucose level for the first 2 postoperative days, long operation time, and use of the instrumentation(p<0.02) were all related predictiors of deep wound infection. Institution of a protocol of postoperative continuous intravenous insulin to maintain blood glucose level less than 200mg/dL was began in september 1997. This protocol resulted in a decrease in blood glucose levels for the first 2 postoperative days and a concomitant decrease in the proportion of patients with deep wound infection, from 8.3%(11/132) to 5.1%(10/195) (p<0.02). Conclusion: The incidence of deep wound infection in diabetic patients is reduced after implementation of a protocol to maintain mean blood glucose level less than 200mg/dL in the immediate postoperative period.

Onion (Allium cepa Linn) has been reported to have hypoglycemic activity in human and several animal models. In the present study, we performed intraperitoneal glucose tolerance test (IPGTT) in young (1.5mo) and aged (5 mo) rats treated with onion in order to determine whether aging can influence on the anti-hy-perglycemic effect of onion. In addition, we investigated the hypoglycemic effect of onion in streptozotocin- induced diabetic rats treated with aqueous extracts of onion (500 mg/kg, i.p., daily) for 4 weeks. Blood glucose level was determined in fasted and fed rats by using a glucometer (Johnson & Johnson). In glucose tolerance test, blood glucose level was maximally increased 15 min after glucose load (2 g/kg, i.p.), and recovered to the basal level 3 hr after glucose challenge in young and old rats. The maximum blood glucose levels of young and aged rat were 184$\pm$7.49 and 225.2$\pm$ 12.55 mg/dl, respectively. A single i.p. injection of aqueous extract of onion (1 g/kg) 30 min before glucose challenge significantly decreased blood glucose levels at 15, 30, 60, 90 min after glucose load in aged rats, while the administration of onion did not show any significant effect in young rats. In onion-treated diabetic rats, significant hypoglycemic effect (p<0.05) was observed, and the effect was greater in fasted rats than in fed. In conclusion, these results suggest that anti-hyperlycemic effect of onion can be changed by age and fasting.

To test if the developed ubiquitous health care devices working well and vital information could be collected and monitored systematically through internet and to test if the devices and services could be used further. Kyungwon University, KT Co., Gil Medical Center, LIG Nex1 Co., and Sujeong Health Center conducted an ubiquitous health care demonstration project in Sujeong-Gu, Sungnam, Korea from Mar. 5 to May 16. We developed and applied several medical devices to monitor health of the elderly in their houses through internet. The devices were sphygmomanometer, glucometer, body fat scale, Health Pad, and activity sensor. We distributed the devices to 20 recipients of home care and 7 diabetes patients. After received the devices and were explained how to use them, they used the devices in their houses. The vital signs of the residents were monitored through internet. A nurse monitored and consulted their vital signs in the monitoring center in Kyungwon University during the demonstration period. The consultant called them and consulted on their blood pressure, blood sugar level, and body fat after a few seconds they used the devices as well as provision of recommended contents such as diets and activities through Health Pad. To investigate cognition and satisfaction of the participants for the devices, we surveyed the participants at the end of the demonstration period. For the change in blood pressure, blood sugar level, and activities, we conducted statistical test. After the demonstration period. cognition and satisfaction for the devices and change in blood pressure, blood sugar level, and activities were evaluated. Most of the participants were acknowledged how to use the device and satisfied with the use of the devices. The internet monitoring and services are considered to be promising because most of the participants were satisfied especially because somebody was monitoring their health status. However some weaknesses such as short battery life of the activity sensor, lack of connection of consultations with hospitals, and low understanding on usage of some of the devices need to be complemented.

This study was carried out along with the 1990 6th National Tuberculosis Prevalence Survey in order to estimate the prevalence rate of diabetes mellitus among a representative adult Korean population. Fasting blood glucose was measured by diastix (Ames) using glucometer II for seventy seven percent of the population (30 year old or above) residing in 190 enumeration districts randomly sampled from 146,944 general ED. The prevalence of diabetes mellitus of the population was estimated by projecting the ratio of ${\geq}200mg/dl\;PP_2$ of fasting blood sugar level below 120 mg/dl by sex to the study population. Fasting blood glucose and 2 hr. postprandial blood glucose were measured on about 3000 subsampled individuals, and diabetes mellitus was defined by the WHO criteria-FBG${\geq}120mg/dl\;or\;PP_2{\geq}200mg/dl$ when FBG is below 120mg/dl. The results obtained are as follows : 1. Estimated prevalence(age adjusted) of diabetes mellitus was 4.6% for male and 8.1% for female. The age adjusted mean FBG was $93.9{\pm}26.2mg/dl$ for male and $102.9{\pm}31.5mg/dl$ for female. 2. The prevalence increased as age advanced with peak in $60{\sim}69$ years old age group for both sexes. 3. The mean FBG and estimated prevalence rate of diabetes mellitus varied considerably among the populations of fifteen cities and provinces ; it vaired from $87.0{\pm}17.7\;to\;104.6{\pm}34.5mg/dl$ and 1.2% to 8.9% for males, and from $93.3{\pm}25.3\;to\;116.7{\pm}38.6mg/dl$ and 3.4% to 20.8% for females. 4. The mean FBG and prevalence rates were higher among the rural population than those residing in metropolitan areas. 5. The proportion of the people previously treated among the diabetics was estimated to be a little less than one fifth. 6. Factors strongly associated with FBG were age, sex, family history of D. M., BMI, area and educational level among eleven variables.
