Evaluation of two methods of rapid blood-glucose monitoring by unskilled personnel during surgery.
The accuracy of two rapid methods of blood-glucose monitoring without (Haemo-glucotest 1-44) and with a reflectance meter (Hypocount B) was compared using a laboratory method. The assessment was carried out by personnel with no previous experience in measuring blood glucose. Eighty-five percent of the 92 measurements obtained with the hypocount B were within +/- 20% of the laboratory glucose values. Using haemo-glucotest 1-44 strips, 74% of the readings were within +/- 20% of the reference laboratory values. For values below 5.5 mmol/l, there was a tendency for results to be too low, with 77% of the readings below laboratory values -20%. All situations with severe hypoglycaemia were detected with both strips. The study also demonstrates the ineffectiveness of s.c. insulin regimens during surgery. Only 47% of the measured blood glucose values were within the range of 5.5-10 mmol/l and two of ten patients had hypoglycaemia with values below 2.5 mmol/l. Therefore glucose monitoring during surgery in diabetics seems justified. This monitoring can be performed adequately with strips.
