Abstract
We assessed the effect of 2% lidocaine with 1:80,000 adrenaline (L + AD) and 3% prilocaine with 0.03 IU/mL felypressin (P + FP) on blood pressure and heart rate in older adults with systemic diseases undergoing dental extraction. This double-blind, randomized crossover study included 22 elderly participants, aged over 65 years. The participants were administered L + AD for one dental extraction and P + FP for the other. Blood pressure and heart rate were recorded immediately, 5, and 10 minutes after local anesthetic administration and the data were analyzed. The systolic and diastolic blood pressures in the P + FP group increased at all measurement points (p < .001). In the L + AD group, the diastolic blood pressure decreased at 5 and 10 minutes after local anesthetic administration (p < .05), whereas the heart rate increased at all measured time points (p < .001). There were statistically significant differences in systolic blood pressure at 5 and 10 minutes after local anesthetic administration and in diastolic blood pressure and heart rate at all time points between the 2 groups. In older adults, P + FP administration increased the systolic and diastolic blood pressures. L + AD administration increased the heart rate and decreased the diastolic blood pressure.
