Abstract:
INTRODUCTION:Incision and drainage of symptomatic emergency patients with facial swelling is painful even after local anesthetics are administered. The purpose of this prospective, randomized, double-blind study was to compare the pain of infiltration and the pain of an incision and drainage procedure of a buffered versus a nonbuffered 4% lidocaine formulation in symptomatic emergency patients presenting with a diagnosis of pulpal necrosis, associated periapical area, and an acute clinical swelling. METHODS:Eighty-eight emergency patients were randomly divided into 2 groups to receive 2 intraoral infiltration injections (mesial and distal to the swelling) of either 4% lidocaine with 1:100,000 epinephrine buffered with 0.18 mL 8.4% sodium bicarbonate using the Onpharma (Los Gatos, CA) buffering system or 4% lidocaine with 1:100,000 epinephrine. Subjects rated the pain of needle insertion, needle placement, and solution deposition for each injection using a 170-mm visual analog scale. An incision and drainage procedure was performed, and subjects rated the pain of incision, drainage, and dissection on a 170-mm visual analog scale. RESULTS:No significant differences between the buffered and nonbuffered 4% lidocaine formulations were found for needle insertion, placement, and solution deposition of the infiltration injections or for the treatment phases of incision, drainage, and dissection. CONCLUSIONS:Buffering a 4% lidocaine formulation did not significantly decrease the pain of infiltrations or significantly decrease the pain of the incision and drainage procedure when compared with a nonbuffered 4% lidocaine formulation in symptomatic patients with a diagnosis of pulpal necrosis and associated acute swelling.
