Onset of Anesthesia in Classical Inferior Alveolar Nerve Block Technique an Observation Study
Abstract
Objective: This study investigates the onset time of anesthesia achieved through the classical inferior alveolar nerve block (IANB) technique, aiming to provide insights into the efficacy and timing of onset for clinical applications.
Methods: An observational study was conducted An observational study was conducted in the month of May 2024 involving 122 patients undergoing dental procedures requiring IANB. After administering the block using the classical technique, the onset of anesthesia was monitored. The primary outcome was the time from injection to the onset of adequate anesthesia, defined as the loss of sensation in the mandibular molar region. Secondary outcomes included variations in onset times related to patient demographics, anatomical factors, and the experience level of the administering clinician.
Results: The average onset time for effective anesthesia was 6.2 minutes, with a range of 3 to 10 minutes. Variability in onset time was observed, influenced by factors such as patient age, anatomical variations, and operator experience. Younger patients and those with less anatomical variation tended to experience faster onset times. Experienced clinicians achieved slightly quicker onset times compared to less experienced practitioners.
Conclusion: The classical inferior alveolar nerve block technique typically achieves effective anesthesia within approximately 6 minutes. Understanding the variability in onset times can assist clinicians in setting realistic expectations for patients and in planning procedural timing. Further research could explore methods to optimize onset times and improve consistency in clinical practice.
