Objectives: This study aimed to evaluate pulse pressure fluctuation on dental local anesthetic administration in diabetic patients with and without coronary heart disease undergoing tooth extraction.
Materials and methods: This retrospective study in diabetic patients undergoing tooth extraction included 33 patients with coronary heart disease (mean age 79.3 ± 7.4, 64% male) and 49 patients without coronary heart disease (mean age 78.6 ± 6.5, 29% male). The increase in pulse pressure before and after administration of local anesthetics was compared between diabetic patients with and without coronary heart disease.
Results: Pulse pressure was increased in male diabetic patients with coronary heart disease compared with those without coronary heart disease following administration of 3% prilocaine hydrochloride with felypressin 0.03 IU/mL (prilocaine) (15.6 ± 15.4 mmHg in those with coronary heart disease (n = 11) versus 4.3 ± 10.9 mmHg in those without coronary heart disease (n = 13), p = 0.03).
Conclusions: Prilocaine administration increased pulse pressure in male diabetic patients with coronary heart disease compared with those without coronary heart disease. Further study is needed to reveal the mechanisms involved in the increase in pulse pressure.
Clinical relevance: This is the first study of pulse pressure fluctuation in diabetic patients with and without coronary heart disease following administration of local anesthetics. Our findings can help guide the choice of local anesthetics and serve as a predictor of coronary vascular condition in diabetic patients during dental treatment.
