Application of intensive blood glucose monitoring in blood glucose management of patients after coronary artery bypass grafting

Objective To investigate the effect of intensive blood glucose monitoring and nursing program on blood glucose variability of patients transferred to general wards after coronary artery bypass grafting (CABG) . Methods A convenient sampling method was used to select 106 patients with coronary heart disease and hyperglycemia who were transferred from the ICU within 72 hours after CABG from Beijing Anzhen Hospital from June to December 2018. They were divided into control group (54 cases) and research group (52 cases) according to the random number table method. The control group was given routine nursing care, and the research group adopted a comprehensive nursing strategy including intensive blood glucose monitoring based on the control group. The average daily blood glucose level (MGL) , standard blood glucose standard deviation (SD) , daily average blood glucose fluctuation range (MAGE) , and blood glucose variation coefficient (CV) of the two groups were compared within 3 days after CABG patients were transferred to the general ward. Results After the patients were transferred from the ICU to the general ward, there were time effects, inter-group effects, and time-group interaction effects in SD; inter-group effects in SD; time- and inter-group effects in MAGE; and inter-group effects and time and group in CV interaction effect. Conclusions Within 1 to 3 days after the patient is transferred from the ICU to the general ward, compared with the conventional nursing group, continued intensive blood glucose monitoring and nursing can reduce the degree of blood glucose variation.
