Abstract
PurposeSignificant vasovagal reaction is one of the untoward events in the course of simple extractions. The present study then aimed to record the patients’ heart rate during the extraction procedure.Materials and methodsInformed consents were obtained in advance. Patients were placed in the dental chair and their heart rate was measured before /and prior to the anesthetic injection, during, and after dental extraction on a pulse oxymeter device. Data were analyzed using paired t-test.ResultsSixty one patients were included. The mean heart rates of these patients prior, during, and after extraction were 88, 86 and 81, respectively. Two by two comparisons showed a significant decrease in the mean heart rate during extraction compared to the baseline and also after extraction compared to both before and during extraction (p < 0.05 for all three).ConclusionsDespite the presence of sufficient local anesthesia and performing the extraction with the least trauma, a significant decrease in heart rate is evident.
Highlights
Two by two comparisons showed a significant decrease in the mean heart rate during extraction compared to the baseline and after extraction compared to both before and during extraction (p < 0.05 for all three)
It has been discussed that tooth avulsion is the most critical point of the extraction procedure in terms of hemodynamic alterations [1,2]
Different authors have found that in healthy normotensive patients, slight elevations of Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) occur up to the moment of extraction followed by a decreased SBP and DBP to levels even lower than those recorded at baseline [1,2]
Summary
It has been discussed that tooth avulsion is the most critical point of the extraction procedure in terms of hemodynamic alterations [1,2]. Different authors have found that in healthy normotensive patients, slight elevations of Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) occur up to the moment of extraction followed by a decreased SBP and DBP to levels even lower than those recorded at baseline [1,2]. This is thought to be attributable to the release of endogenous adrenaline as a reaction to the noxus [5,6]. Heart Rate (HR) and Blood Pressure (BP) and other clinical hemodynamic alterations throughout the extraction procedures are a factor of
