简要总结
This is a study about the dynamics and effects of different types of blocks (intraoral conduction anesthesia of the alveolar nerve and extraoral US block of the mandibular nerve) for extraction of lower third molars.
详细描述
Standard method of anesthesia for extraction of horizontally positioned lower thirdmolars is intraoral conduction anesthesia of the inferior alveolar nerve. However, the analgesiceffect of block is short and it is necessary to use analgesics. In this prospective clinical study,analgesic effect of ultrasound (US) -guided extraoral block of mandibular nerve will beinvestigated, in order to prolong pain-free time and reduce the use of analgesics associated withrisks (bleeding, hepatotoxicity).
Characteristics of alveolar nerve block and US block of the mandibular nerve will becompared, such as: pain during application of anesthesia, amount of anesthetic, duration ofanesthesia, need to use analgesics, time to and level of pain when using analgesics, andcomplications
