ABSTRACT
BACKGROUND: The STG-22 is the only continuous blood glucose monitoring system currently available. The aim of this study is to determine the accuracy and reliability of the STG-22 for continuously monitoring blood glucose level in post-surgical patients. METHODS: Fifty patients scheduled for routine surgery were studied in surgical intensive care unit (ICU) of a university hospital. After admission to the ICU, the STG-22 was connected to the patients. An attending physician obtained blood samples from a radial arterial catheter. Blood glucose level was measured using the ABL800FLEX immediately after blood collection at 0, 4, 8, and 16 h post-admission to the ICU (total of 200 blood glucose values). RESULTS: The correlation coefficient (R2) was 0.96. In the Clarke error grid, 100% of the paired measurements were in the clinically acceptable zone A and B. The Bland and Altman analysis showed that bias+/-limits of agreement (percent error) were 0.04(0.7)+/-0.35(6.3) mmol (mg/dl) (7%), -0.11(-2)+/-1.22(22) (15%) and -0.33(-6)+/-1.28(23) (10%) in hypoglycemia (<70(3.89) mmol (mg/dl), normoglycemia (3.89(70)-10(180) mmol (mg/dl), and hyperglycemia (>10(180) mmol (mg/dl), respectively. CONCLUSIONS: The STG-22 can be used for measuring blood glucose level continuously and measurement results are consistent with intermittent measurement (percentage error within 15%). Therefore, the STG-22 is a useful device for monitoring in blood glucose level in the ICU for 16 h.

A descriptive correlational study was used to evaluate the correlation/agreement of oral and axillary temperature measurements to patient core temperatures obtained in the OR. Data collectors recorded oral or axillary patient temperature from 752 patients on admission and discharge from the PACU. Results indicated that there was a moderate correlation between each of the current devices and core temperature, but no agreement between core temperature and either device. Recommendations were made to use just one device throughout the organization, or to use the device used on admission throughout the hospitalization.

A variety of illnesses and other complications have been attributed to problems resulting from use of medical devices, implants, and instruments. A new law has implications for all health care facilities using medical devices. The Safe Medical Devices Act (SMDA) of 1990 mandates the reporting of complications related to the use of medical devices to the United States Food and Drug Administration. Reporting requirements of the SMDA could challenge the efficiency of information systems in health care facilities and add to the responsibilities of staff nurses. In the following article, the author discusses some implications of the new law.
