Validation Study: Utilization of Blood from the Oral Surgical Extraction Site for Perioperative Blood Glucose Monitoring

Blood glucose (BG) monitoring is an essential component of perioperative patient management under general anesthesia. This study demonstrates that BG levels obtained from oral surgical extraction sites are statistically comparable to samples obtained from the venous and ear pinna sites. Utilizing the oral surgical extraction site for BG measurement offers a practical alternative, thereby reducing the need for frequent venipuncture or ear pinna capillary puncture. In this study, 51 patients (38 canines and 13 felines) had BG measurements obtained from their oral surgical extraction sites, peripheral venous sites and ear pinnae resulting in 153 total samples. The analysis revealed there was no statistically significant difference in BG measurements between sampling sites. This study showed that oral surgical extraction sites provide a viable and accessible alternative for BG monitoring in feline and canine patients.
