High blood-sugar levels indicate greater chance of death for critically ill patients

10.12.2003


Mayo Clinic Proceedings study emphasizes blood sugar level management



A study in the December issue of Mayo Clinic Proceedings on blood-sugar levels in 1,826 intensive care unit patients showed that hyperglycemia (high blood-sugar levels) increased the patient’s chance of death. The findings have important implications for the management of blood sugar in critically ill patients.

Even a modest degree of hyperglycemia was associated with a substantial increase in deaths in patients with a wide range of medical and surgical diagnoses, says James Krinsley, M.D., director of critical care at The Stamford Hospital in Stamford, Conn., and author of the study.


Hyperglycemia is common in critically ill adults. Standard clinical practice has been to tolerate a moderate degree of hyperglycemia in these patients. However, Dr. Krinsley says the findings from this study suggest a new approach to glucose management in the intensive care unit, and should prompt additional studies.

"Although hyperglycemia can be a marker of severity of illness, it may also worsen outcomes," Dr. Krinsley says. "We think that tight glucose control results in improved vascular function and lower risk of infection."

Dr. Krinsley, who is an associate clinical professor of medicine at the Columbia University College of Physicians and Surgeons, reviewed data for 1,826 patients whose glucose values were obtained during their intensive care unit stay at The Stamford Hospital between Oct. 1, 1999, and April 4, 2002. The lowest death rates occurred in patients whose average glucose levels were in the lower end of the normal range. Death rates increased as the average glucose levels increased. This association was noted among people with and without diabetes.

Based on these findings, a multidisciplinary team at The Stamford Hospital has developed a protocol for intensive monitoring and treatment of glucose levels of patients admitted to the critical care unit. The team is studying whether tighter management of glucose levels in the intensive care unit will result in lower death rates and lower organ system dysfunction. Dr. Krinsley will be reporting those results soon.

An editorial in the same issue of Mayo Clinic Proceedings, authored by Douglas Coursin, M.D., of the departments of Anesthesiology and Internal Medicine at the University of Wisconsin-Madison, and Michael Murray, Ph.D., M.D., of the Department of Anesthesiology at Mayo Clinic in Jacksonville, Fla., says the report provides potentially useful information and the basis for further studies. The study provides some insights into the generalized applicability of normal blood-sugar levels in a wide range of adult intensive care unit patients, say Drs. Coursin and Murray.

The editorialists say randomized controlled studies of a broader and greater range of patients need to be done to allow for analysis of subsets of patients, including critically ill adults and pediatric patients -- be they medical, surgical, transplantation, neurologic, trauma or other patients.


###
The Stamford Hospital is a major teaching affiliate of the Columbia University College of Physicians and Surgeons. In 2002 the National Coalition of Healthcare and the Institute for Healthcare Improvement recognized the hospital’s intensive care unit as one of 11 "best practices" in the nation for its work in integrating a comprehensive data system with multiple clinical protocols to improve patient outcomes.

A peer-reviewed journal, Mayo Clinic Proceedings publishes original articles and reviews dealing with clinical and laboratory medicine, clinical research, basic science research and clinical epidemiology. Mayo Clinic Proceedings is published monthly by Mayo Clinic as part of its commitment to the medical education of physicians. The journal has been published for more than 75 years and has a circulation of 130,000 nationally and internationally.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
