Key result
During dental surgical procedures, 22.2% of patients with normal preoperative blood pressure reached the stage of hypertension intraoperatively, primarily attributed to surgical stress.
Why the study?
The study aimed to evaluate the occurrence of significant changes in systemic blood pressure during surgical-dental procedures.
Does dental surgery with local anesthesia cause significant changes in blood pressure?
Observational (n=135)
No
Does dental surgery with local anesthesia cause significant changes in blood pressure?
Dental surgical procedures induce significant transient increases in blood pressure during the intraoperative period, likely due to surgical stress rather than the type of local anesthetic used.
May support BP monitoring during dental procedures; leaves open whether routine screening improves outcomes in larger cohorts.
The present study aimed to evaluate the occurrence of significant changes in systemic blood pressure (SBP) during surgical-dental procedures. A prospective study was performed with a sample of 135 randomly selected individuals who underwent surgical procedures at the Bucomaxillofacial Surgery Clinic of the Dentistry School of the ESFA (ES) between the second half of 2017 and April 2018. After consent, sociodemographic, lifestyle data, weight and height were obtained through a questionnaire, weighing and measurement, respectively. BP measurements were performed at three moments: preoperative (BP1), intraoperative (BP2) and postoperative (BP3) using a mercury column sphygmomanometer and stethoscope. Values <120/80 mmHg were used as normal values. When BP1 and BP2 were compared, 63.0% remained within normal values and 22.2% reached the stage of hypertension. In the comparison of BP1 and BP3, 66.7% remained normal, and only 7.4% reached the stage of hypertension. When BP2 and BP3 were compared, 53.6% remained within the normality stage and 12.2% reached the stage of hypertension. It was concluded that there were variations in blood pressure, being the largest variation found in BP2, and can be attributed to the stress caused by the surgical act, since no statistically significant connections were found between the changes in blood pressure and the anesthetics used in the research.

Andrade et al. (2021) conducted an observational in Patients undergoing dental surgical procedures (n=135). Dental surgical procedures vs. Preoperative baseline was evaluated on Progression to hypertension intraoperatively (BP2) among patients with normal preoperative blood pressure (BP1) (p=<0.001). During dental surgical procedures, 22.2% of patients with normal preoperative blood pressure reached the stage of hypertension intraoperatively, primarily attributed to surgical stress.
