Design outcomes

Primary

MeasureTime frame
Sensitivity of preoperative 75g-OGTT to predict intraoperative hyperglycemia End of surgery Calculation of sensitivity base on preoperative OGTT classification and the occurrence of intraoperative hyperglycemia. Data collected via pre-op blood tests and hourly intraoperative POC- glucose.

Secondary

MeasureTime frame
Effect of intraoperative hyperglycemia on surgical outcomes. post operative period at hospital discharge, 30 days post operation. Comparison of postoperative outcomes between patient who developed intraoperative hyperglycemia and who did not, using appropiate statistical analyses .
