INS and Hyperglycemia: This difference can be explained if we consider the different rates of absorption and conversion of the precursors used into glucose for treatment in groups A and B. According to Herdt and Emery [23] an i.v. infusion of glucose immediately causes an increase in blood glucose concentration resulting in transient hyperglycaemia, which we did not observe in our research as a consequence of the insulin subcutaneous infusion immediately after the glucose infusion, since this promotes the rapid glucose uptake and utilization by peripheral tissues [14].
