Abstract
Background: Adrenaline functions as a vasoconstrictor in local anesthesia, prolonging the working duration of the anesthetic solution and reducing the risk of lidocaine toxicity. The most common ratio is 1:80,000, but this ratio is not safe for hypertensive patients because it can increase blood pressure.
Objective: This study compares blood pressure before and after using local anesthesia (lidocaine 2% and adrenaline 1:200,000) in hypertensive patients.
Methods: The study employed analytical research involving consecutive sampling and randomized clinical trials after ethical approval. The population of the study consisted of patients who met the inclusion criteria, such as systolic blood pressure between 131 - 161 mmHg and diastolic blood pressure between 81 - 99 mmHg, who underwent closed method extraction with local anesthesia containing lidocaine 2% and adrenaline 1:200.000. Blood pressure was measured with a sphygmomanometer before and after anesthesia injection. The measurement results were recorded and analyzed statistically with a paired T-test.
Results: There was no difference between before and after injection of local anesthesia using lidocaine and adrenaline (1:200,000) in hypertensive patients.
Conclusions: Local anesthesia containing lidocaine and adrenaline 1:200,000 does not change blood pressure, so it is safe for hypertensive patients.
