Evolution of Hemodynamic Parameters After Tooth Extraction and Infiltration of Local Anesthetic with Vasoconstrictor in Healthy and Hypertensive Patients Controlled with Different Antihypertensive Drugs

Abstract: Background: The progressive aging of the population has led to an increased prevalence of chronic diseases and polypharmacy, with arterial hypertension representing one of the most frequent conditions. Consequently, the management of vital signs during dental interventions, such as tooth extractions, has acquired particular clinical relevance. The present study aimed to analyze the hemodynamic impact of vasoconstrictors (VAs) used in local anesthesia (LA) at different procedural stages in patients with pharmacologically controlled hypertension, as well as to compare these effects with those observed in normotensive individuals. Additionally, the study evaluated the influence of antihypertensive medication on hemodynamic responses during dental extraction. Methods: A case–control study was conducted at Dr. Peset University Hospital (Valencia, Spain), including 254 patients—148 hypertensive (controlled with type 1 and 2 antihypertensive therapy) and 106 normotensive controls. Hemodynamic parameters—systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), and oxygen saturation (SO2)—were recorded at four time points: baseline (T1), five minutes post anesthesia with 4% articaine and epinephrine (T2), upon completion of extraction (T3), and one week postoperatively (T4). Results: The SBP remained more stable in normotensive patients, while both groups exhibited a slight DBP decrease at T2, with recovery by T3. In hypertensive patients treated with angiotensin receptor blockers (ARBs), DBP decreased further. Tooth extraction under controlled hypertension conditions caused a mild, clinically insignificant increase in HR. Conclusions: Significant fluctuations in SBP, DBP, and SO2 occurred during dental extraction, underscoring the necessity for vigilant intraoperative monitoring and individualized management of hypertensive patients.
