ABSTRACT

Introduction: Preoperative laboratory tests are routinely ordered as part of the perioperative assessment protocol in oral surgery procedures, in order to identify asymptomatic or symptomatic pathologies and so avoid perioperative complications. Objective: To identify the type and frequency of abnormalities detected in the routine preoperative laboratory tests requested for candidates for oral surgery under local anesthesia. Material and methods: The routine preoperative laboratory tests (complete blood count, blood chemistry, and coagulation tests) of 160 consecutive adult patients (≥ 16 years old) of ASA (American Society of Anesthesiologists) physical status I and II and who were candidates for oral surgery under local anesthesia were reviewed. Abnormalities in baseline values were identified and the clinical significance of these results determined, based on the cutoff values for disease diagnosis. Results: One hundred two patients (64%) were found to have at least one preoperative laboratory test in which one or more of the baseline values showed abnormalities; of these, 50 (31%) of the results had a clinical impact. Patients aged ≥ 40 and ASA I patients displayed a higher frequency of clinically significant abnormalities (80 and 66% of cases, respectively). The most common finding was hypercholesterolemia (30% of cases). Conclusions: The results obtained in this study highlight the importance of using routine preoperative laboratory tests in oral surgery to detect asymptomatic or symptomatic abnormalities requiring prior management and so prevent perioperative complications.
