(June 16, 2009 - Insidermedicine) From Québec - According to research in the journal Circulation, severe obesity can increase the risk of surgical complications. The researchers note that physical examination and electrocardiogram often underestimate cardiac dysfunction in those that are obese. Also, bariatric surgery has become increasingly in demand and is associated with higher risks of cardiac complications than other forms of surgery.

From Switzerland - According to research in the Archives of Surgery, punctures in surgical gloves may increase the risk of surgical site infections. In a study of over 4,100 surgical procedures, researchers found that patients who were not treated with antibiotic prophylaxis had a four times increased risk of infection if gloves were punctured during a procedure. Overall, the rate of surgical site infection was 4.5%.

And finally, from Maryland - According to research in the Annals of Internal Medicine, the risk of complications associated with colonoscopy increases with age. In a study of over 53,000 adults over the age of 70, researchers found that the risk of gastrointestinal bleeding or perforation was 75% higher among those aged 80 to 84 than those aged 66 to 69. Colonoscopy is not recommended for those older than 85.
