High pre-op blood sugar levels increases risk of blood clots

Patients who have high blood sugar levels before undergoing surgery run an increased risk of developing post-operative blood clots, deep vein thrombosis and pulmonary embolism, a new US study reveals.

Patients who have high blood sugar levels before undergoing surgery run an increased risk of developing post-operative blood clots, deep vein thrombosis and pulmonary embolism, a new US study reveals.

Researchers in Philadelphia examined records of nearly 6,500 hip or knee replacement patients admitted to a hospital between 2003 and 2005 and asked what happened to patients with high blood glucose levels,which was not controlled well prior to surgery.

Of these patients, 38 had very high blood glucose on the day on the day of surgery and around 11% of this groupdeveloped a pulmonary embolism post-surgery.

The authors say the data suggests that if an individual has high blood glucose and is coming for surgery, he or she should be receive treatment to recommended levels before going ahead with the operation.

Results of the study were reported at the annual meeting of the the American Society of Anaesthesiologists in Chicago on October 15 2006.
