Comparison of glycemic control methods in open heart surgery

Noting the need for less laborious methods of blood sugar control during open-heart surgery, particularly in diabetic patients at higher risk of developing complications, co-principal investigators Roland Kaddoum and Amro Khalili and their colleagues evaluated an automated blood glucose monitoring system. They found that the automated glucose pump effectively kept diabetic patients within predefined glucose ranges during surgery. The study was published in BMC Anesthesiology.

The researchers recruited patients between the ages of 40 and 75 and randomized them to receive either the experimental automated system or the conventional technique. According to the article, the researchers observed that the proportion of patients remained between 7.8 and 10 mmol.l-1 was not statistically different between the two groups.

However, they noted that 14 (26.7%) patients in the experimental group maintained their blood sugar levels within a safe range of 6.7 to 10 mmol.l-1significantly higher than the 5 (17.2%) patients in the control group who did (P=.025).

In addition, 17 (58.6%) patients in the control group experienced at least one intraoperative hyperglycemic event, compared to 5 (17.2%) in the experimental group (P

Overall, the authors determined that the automated blood glucose monitoring system kept most diabetic patients undergoing open-heart surgery within a predefined perioperative blood glucose range, with very low rates of hyperglycemia and hypoglycemia. . They proposed that this method “is less laborious in terms of the interventions of the anesthesiologist”.
